DETAILED DESCRIPTION
[00027] Compositions comprising non-fluorinated polyhedral oligomeric silsesquioxane (POSS)-based compounds, and related articles, methods, and kits, are generally described. In an exemplary set of embodiments, the non-fluorinated POSS-based compound comprises a POSS molecule functionalized with a variety of suitable functional groups, including, for example, polydialkylsiloxane (e.g., polydimethylsiloxane) groups, tris(trialkylsiloxy)silane (e.g., tris(trimethylsiloxy)silane) groups, (meth)acrylate groups, phenyl groups, substituted phenyl groups, amine groups, azide groups, isocyanate groups, -C1-C10 alkyl groups, allyl groups, alcohol groups, epoxy groups, thiol groups, and/or acidic groups. In some cases, the structure of the non-fluorinated POSS -based compound may advantageously be tuned depending on a particular application. For example, in some embodiments (e.g., wherein a hydrophobic and/or low surface energy material is desirable), the POSS molecule comprises one or more polydialkylsiloxane groups. In some embodiments (e.g., wherein a material capable of crosslinking is desirable), the POSS molecule comprises one or more (meth)acrylate groups. [00028] In some embodiments, the non-fluorinated POSS-based compound is configured such that each silicon atom of the POSS molecule is functionalized with the same functional group. In other embodiments, the non-fluorinated POSS-based compound is multifunctional such that each silicon atom of the POSS molecule is functionalized with a functional group, wherein at least two functional groups are different (e.g., chemically different). Advantageously, the multifunctionalized POSS-based compound may have multiple functionalities and/or uses. For example, in some embodiments (e.g., wherein both a hydrophobic and/or low surface energy material and a material capable of crosslinking is desirable), the POSS molecule comprises one or more polydialky I siloxane groups and one or more (meth)acrylate groups. Other combinations of functional groups are possible and a person of ordinary skill in the art would be capable of selecting such functional groups depending on the particular application, based upon the teachings of this specification.
[00029] According to some embodiments, the non-fluorinated POSS-based compound is configured such that at least one functional group of the POSS molecule is a bridging moiety to another POSS molecule. For example, in some embodiments, the POSS-based compound comprises a first POSS molecule functionalized with one or more (meth)acrylate groups that form a bond to a second POSS molecule. In some cases, embodiments in which at least one functional group of the POSS molecule is a bridging moiety to another POSS molecule advantageously provides extended structures of POSS-based dimers, oligomers, and/or polymers. In some embodiments, each monomer of the POSS-based dimer, oligomer, and/or polymer has the same or different functionalities. [00030] In some embodiments, the non-fluorinated POSS-based compounds described herein are used as additives in compositions comprising one or more base polymers (e.g., resins such as epoxy-containing resins and/or (meth)acry late-containing resins). In some embodiments, the non-fluorinated POSS-based additive is configured to interact (e.g., crosslink) with the one or more base polymers. In some embodiments, the use of a non-fluorinated POSS-based additive results in the composition having an advantageously low surface energy, e.g., as compared to a composition that is otherwise equivalent but does not comprise the non-fluorinated POSS-based additive. For example, in some embodiments, a composition comprising the non-fluorinated POSS-based compound has a coefficient of friction less than or equal to 0.1. In some embodiments, the resulting compositions are used as coatings on a wide variety of substrates, including, for example, glass, ceramics, metals, metal oxides, and/or polymers.
[00031] While much of the description herein and below generally relates to POSS-based compounds comprising POSS molecules having 8 Si tetrahedral vertices (T vertices), those of ordinary skill in the art would understand, based upon the teachings of this specification, that other lower-order and/or higher-order POSS molecules are also possible. For example, in some embodiments, POSS molecules comprising 4 Si T vertices, 6 Si T vertices, 10 Si T vertices, and/or 12 Si T vertices, or more, are possible. As such, the concepts described herein are, in some embodiments, applicable to POSS molecules comprising 4 Si T vertices, 6 Si T vertices, 8 Si T vertices, 10 Si T vertices, and/or 12 Si T vertices. In some embodiments, a POSS-based compound (e.g., a POSS-based additive) comprises a plurality of POSS molecules, each POSS molecule having the same or different number of Si tetrahedral vertices. In an exemplary set of embodiments, each POSS molecule has 8 Si T vertices as depicted in Formula (I), below.
[00032] In some embodiments, the POSS molecule has a formula as in SizO1.5zR1 z, where each R1 is the same or different and is selected from the group consisting of-O-Si(R2)2-(R3)x- Si(R2)2-O-[Si(R2)2-O]n-Si(R2)3, -O-Si(R2)2-(R3)x-Si(OSi(R2)3)3, -O-Si(R2)2-(R3)x-O-C(O)- C(CH3)(CH2), -O-Si(R2)2-(R3)x-C(O)-O-(R3)x- -O-Si(R2)2-(R3)x-O-CH2CHCH2, -(R3)x-C6H5, - (R3)x-C6H4-(R3)x-(R2)y,-(R3)x-NH2, -(R3)x-NH-R2, -(R3)x-N3, -(N)=C=O, -(R3)x-(R2)y, -(R3)x- OH, -(R3) X-(C2H4O), and — (R3)x-SH, any of which may be optionally substituted, wherein each R2 is the same or different and is selected from the group consisting of hydrogen, deuterium, - C1-C10 alkyl, -C2-C10 alkenyl, -C3-C10 alkynyl, and aryl, any of which may be optionally substituted, and wherein each R3 is the same or different and is selected from the group consisting of a bond, oxygen, C(O), -C1-C10 alkylene-, -C2-C10 alkenylene-, -C3-C10 alkynylene- and aryl, any of which may be optionally substituted.
[00033] In some embodiments z is greater than or equal to 4, greater than or equal to 5, greater than or equal to 6, greater than or equal to 7, greater than or equal to 8, greater than or equal to 9, greater than or equal to 10, greater than or equal to 11, or greater than or equal to 12.

[00155] Turning to the figures, specific non-limiting embodiments are described in further detail. It should be understood that the various systems, components, features, and methods described relative to these embodiments may be used either individually and/or in any desired combination as the disclosure is not limited to only the specific embodiments described herein.
[00156] FIG. 1 shows, according to some embodiments, a schematic diagram of an exemplary article. In some embodiments, article 100 comprises substrate 110 comprising at least one surface 120. Suitable substrate materials are described in greater detail elsewhere herein.
[00157] In accordance with some embodiments, composition 130 is disposed on at least a portion of at least one surface 120 of substrate 110 such that composition 130 coats at least the portion of at least one surface 120 of substrate 110. In some embodiments, composition 130 comprises a low surface energy material comprising a POSS-based compound, as described in greater detail elsewhere herein.
[00158] The composition coating the surface of the substrate may have any of a variety of suitable thicknesses. Referring to FIG. 1, for example, composition 130 coating at least the portion of at least one surface 120 of substrate 110 has thickness 132. In some embodiments, the composition coating the surface has an average thickness of greater than or equal to 5 nm, greater than or equal to 10 nm, greater than or equal to 20 nm, greater than or equal to 30 nm, greater than or equal to 40 nm, greater than or equal to 50 nm, greater than or equal to 60 nm, greater than or equal to 70 nm, greater than or equal to 80 nm, or greater than or equal to 90 nm. In some embodiments, the composition coating the surface has an average thickness of less than or equal to 100 nm, less than or equal to 90 nm, less than or equal to 80 nm, less than or equal to 70 nm, less than or equal to 60 nm, less than or equal to 50 nm, less than or equal to 40 nm, less than or equal to 30 nm, less than or equal to 20 nm, or less than or equal to 10 nm.
Combinations of the above recited ranges are possible (e.g., the composition coating the surface has an average thickness of greater than or equal to 5 nm and less than or equal to 100 nm, the composition coating the surface has an average thickness of greater than or equal to 40 nm and less than or equal to 60 nm). Other ranges are also possible. In some embodiments, the average thickness of the composition coating the surface is determined by ellipsometry.
[00159] While composition 130 coating surface 120 of substrate 110 is depicted in FIG. 1 as a smooth layer of uniform thickness, those of ordinary skill in the art would understand that this is for illustration purposes only and the thickness of the composition coating the surface of the substrate may have a particular roughness and/or may vary in thickness, in accordance with some embodiments. In some embodiments, the composition coating the surface of the substrate is of relatively uniform thickness (e.g., within less than or equal to 10% of the total thickness) over at least a substantial portion of the surface of the substrate (e.g., greater than or equal to 75% of the surface area of the surface of the substrate on which the composition is disposed). [00160] According to certain embodiments, the composition coating the surface of the substrate may comprise a plurality of features. In some embodiments, for example, the composition coating the surface of the substrate comprises a plurality of microscale and/or nanoscale features. In some embodiments, the plurality of features may advantageously render the composition more hydrophobic as compared to a composition that does not comprise the plurality of microscale and/or nanoscale features but is otherwise equivalent. For example, in some embodiments, a composition comprising a plurality of features may have a water contact angle greater than or equal to 120°.
[00161] In some embodiments, the plurality of features comprise at least one member selected from the group consisting of particles, amorphous particles, substantially spherical particles, posts, nanoneedles, microneedles, nanograss, micrograss, pores, grooves, ridges, and/or combinations thereof. According to some embodiments, the plurality of features may be formed as the composition is deposited on the surface of the substrate.
[00162] According to some embodiments, at least a portion of the composition comprising the low surface energy material is immobilized on at least the portion of the at least one surface of the substrate. Referring to FIG. 1, for example, at least a portion of composition 130 is immobilized on at least the portion of at least one surface 120 of substrate 110.

[00163] In some embodiments, an article comprising the composition comprising the POSS-based compound is substantially non-fluorinated. For example, in some embodiments, the article comprises fluorine in an amount less than or equal to 5 wt.%, less than or equal to 4 wt.%, less than or equal to 3 wt.%, less than or equal to 2 wt.%, less than or equal to 1 wt.%, less than or equal to 0.5 wt.%, or less than or equal to 0.2 wt.% versus a total weight of the article. In some embodiments, the article comprises fluorine in an amount greater than or equal to 0 wt.%, greater than or equal to 0.2 wt.%, greater than or equal to 0.5 wt.%, greater than or equal to 1 wt.%, greater than or equal to 2 wt.%, greater than or equal to 3 wt.%, or greater than or equal to 4 wt.% versus a total weight of the article. Combinations of the above recited ranges are possible (e.g., the article comprises fluorine in an amount less than or equal to 5 wt.% and greater than or equal to 0 wt.% versus a total weight percent of the article, the article comprises fluorine in an amount less than or equal to 2 wt.% and greater than or equal to 1 wt.% versus a total weight of the article). Other ranges are also possible.
[00164] In some non-limiting embodiments, the article comprising the composition comprising the POSS-based compound is non-fluorinated such that the article comprises fluorine in an amount of 0 wt.% versus a total weight of the article. [00165] According to some embodiments, the substrate is optically transparent. The substrate may have any of a variety of suitable percent optical transmittances. In some embodiments, for example, the percent optical transmittance of the substrate is greater than or equal to 90%, greater than or equal to 92%, greater than or equal to 94%, greater than or equal to 96%, greater than or equal to 98%, or greater than or equal to 99%.

Other ranges are also possible. According to some embodiments, the percent optical transmittance of the substrate is determined using a spectrophotometer.
[00166] The substrate may comprise any of a variety of suitable materials. In some embodiments, for example, the substrate comprises glass, a ceramic, a metal, a metal oxide, a polymer (e.g., an acrylic polymer, a plastic), an electronic component (e.g., a silicon wafer), and/or combinations thereof. Other materials are also possible.
[00167] According to some embodiments, a method of coating a substrate is described. FIG. 2 shows, according to some embodiments, a schematic diagram of an exemplary method of coating a substrate.
[00168] In some embodiments, step 202 of method 200 comprises providing substrate 110 comprising at least one surface 120. According to some embodiments, the method comprises activating at least a portion the substrate. In some embodiments, for example, the substrate is activated by exposing the substrate to a plasma of inert gas, such as, but not limited to, argon (Ar), neon (Ne), helium (He), nitrogen (N2), oxygen (O2), water (H2O), and/or mixtures thereof. In some embodiments, the substrate is activated by corona treatment. In some embodiments, the substrate is activated by mechanically treating the surface (e.g., with a metal oxide). In some embodiments, the substrate is activated by acid etching (e.g., with piranha solution (a mixture of sulfuric acid and hydrogen peroxide), hydrofluoric acid, and/or hydrochloric acid). Without wishing to be bound by any particular theory, as a result of activating the substrate, the density of hydroxyl (-OH) moieties on the surface of the substrate is increased, thereby facilitating immobilization (e.g., bonding) of at least a portion of the composition on the surface of the substrate, as described in greater detail elsewhere herein.
[00169] Step 204 of method 200 comprises, in accordance with some embodiments, disposing (e.g., depositing) composition 130 on at least a portion of at least one surface 120 of substrate 110 such that composition 130 coats at least the portion of at least one surface 120 of substrate 110. In some embodiments, as described in greater detail elsewhere herein, as a result of disposing the composition on at least a portion of the at least one surface of the substrate, at least a portion of the composition is immobilized on (e.g., bound to) the surface of the substrate, as described in greater detail elsewhere herein.
[00170] According to some embodiments, although not shown in the figures, the composition is disposed (e.g., deposited) on at least a portion of more than one surface of the substrate (e.g., two surfaces of the substrate, three surfaces of the substrate, four surfaces of the substrate, etc.).
[00171] Depositing the composition on at least the portion of the at least one surface of the substrate may comprise any of a variety of suitable deposition methods. According to some embodiments, for example, depositing the composition comprises spraying (e.g., spray coating), spinning (e.g., spin coating), dipping (e.g., dip coating), wiping, chemical vapor deposition (CVD), physical vapor deposition (PVD), and/or combinations thereof.
[00172] Step 206 of method 200 comprises, in some embodiments, applying heat 132 to composition 130 after depositing composition 130 on at least the portion of at least one surface 120 of substrate 110. In some embodiments, for example, applying heat to the composition comprises curing and/or annealing the composition. Other methods of applying heat to the composition are also possible.
[00173] The composition may be heated (e.g., cured) to any of a variety of suitable temperatures. In some embodiments, for example, the composition is heated to a temperature of greater than or equal to 25 °C, greater than or equal to 50 °C, greater than or equal to 75 °C, greater than or equal to 100 °C, greater than or equal to 110 °C, greater than or equal to 120 °C, greater than or equal to 130 °C, or greater than or equal to 140 °C. In some embodiments, the composition is heated to a temperature of less than or equal to 150 °C, less than or equal to 140 °C, less than or equal to 130 °C, less than or equal to 120 °C, less than or equal to 110 °C, less than or equal to 100 °C, less than or equal to 75 °C, or less than or equal to 50 °C. Combinations of the above recited ranges are possible (e.g., the composition is heated to a temperature of greater than or equal to 25 °C and less than or equal to 150 °C, the composition is heated to a temperature of greater than or equal to 120 °C and less than or equal to 140 °C). Other ranges are also possible.
[00174] The composition may be heated (e.g., cured) to any of the aforementioned temperatures for any of a variety of suitable times. In some embodiments, for example, the composition is heated for greater than or equal to 1 minute, greater than or equal to 30 minutes, greater than or equal to 1 hour, greater than or equal to 5 hours, greater than or equal to 10 hours, greater than or equal to 24 hours, greater than or equal to 48 hours, or greater than or equal to 72 hours. In some embodiments, the composition is heated for less than or equal to 96 hours, less than or equal to 72 hours, less than or equal to 48 hours, less than or equal to 24 hours, less than or equal to 10 horns, less than or equal to 5 hours, less than or equal to 1 hour, or less than or equal to 30 minutes. Combinations of the above recited ranges are possible (e.g., the composition is heated for greater than or equal to 1 minute and less than or equal to 96 hours, the composition is heated for greater than or equal to 10 horns and less than or equal to 24 hours). Other ranges are also possible.
[00175] In some embodiments, the amount of time that the composition is heated (e.g., cured) depends on the temperature at which the composition is heated. In some embodiments, for example, higher heating temperatures (e.g., greater than or equal to 100 °C) are associated with shorter heating times (e.g., less than or equal to 1 hour). In some embodiments, lower heating temperatures (e.g., less than or equal to 75 °C) are associated with longer heating times (e.g., greater than or equal to 5 hours).
[00176] In some embodiments, the amount of time that the composition is heated (e.g., cured) and/or the temperature at which the composition is heated depends on the substrate on which the composition is disposed (e.g., deposited). In some embodiments, for example, higher- heating temperatures (e.g., greater than or equal to 100 °C) and shorter heating times (e.g., less than or equal to 1 hour) are associated with compositions disposed on glass substrates. In some embodiments, lower heating temperatures (e.g., less than or equal to 75 °C) and longer heating times (e.g., greater than or equal to 5 hours) are associated with compositions disposed on polymer (e.g., plastic) substrates.
[00177] According to some embodiments, applying heat 132 to composition 130 disposed on at least the portion of at least one surface 120 of substrate 110 results in article 100, as shown in step 208 of method 200.
[00178] According to some embodiments, a kit is described. In some embodiments, the kit comprises a low surface energy material comprising a POSS-based compound, as described herein in greater detail. According to some embodiments, the low surface energy material is provided as a solid, and the kit comprises one or more solvents configured to dissolve the low surface energy material. In other embodiments, the low surface energy material is provided in solution. For example, in some embodiments, the kit comprises the low surface energy material pre-dissolved in one or more solvents and ready for application onto a surface of a substrate.
[00179] In some embodiments, the kit comprises one or more precursors configured to form a POSS-based compound. For example, in some embodiments, the kit comprises a precursor POSS molecule, one or more precursor compounds comprising one or more functional groups, and one or more catalysts. In other embodiments, the kit comprises one or more silicon- containing precursor compounds comprising one or more functional groups and one or more catalysts.
[00180] In some embodiments, the one or more precursors configured to form the POSS- based compound and/or the one or more catalysts is provided as a solid, and the kit comprises one or more solvents configured to dissolve the one or more precursors. In other embodiments, the one or more precursors configured to form the POSS-based compound and/or the one or more catalysts are provided in solution.

In some embodiments, for example, the kit comprises one or more base polymers. In some embodiments, the one or more base polymers comprise an epoxy and/or a (meth)acrylate such that the one or more base polymers are configured to interact with the POSS-based compound.
[00182] Definitions of specific functional groups and chemical terms are described in more detail below. For purposes of this invention, the chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75th Ed., inside cover, and specific functional groups are generally defined as described therein and are incorporated herein by reference in their entirety.

[00183] It will be appreciated that the compounds, as described herein, may be substituted with any number of substituents or functional moieties. In general, the term “substituted” whether preceded by the term “optionally” or not, and substituents contained in formulas of this invention, refer to the replacement of hydrogen radicals in a given structure with the radical of a specified substituent (e.g., a substituent which upon substitution results in a stable compound, such as a compound which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, or other reaction). When more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position.
[00184] As used herein, the term “substituted” is contemplated to include all permissible substituents of organic compounds, “permissible” being in the context of the chemical rules of valence known to those of ordinary skill in the art, and includes any of the substituents described herein that results in the formation of a stable compound. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and nonaromatic substituents of organic compounds. For purposes of this invention, heteroatoms such as nitrogen may have hydrogen substituents and/or any permissible substituents of organic compounds described herein which satisfy the valencies of the heteroatoms and results in the formation of a stable moiety. Furthermore, this invention is not intended to be limited in any manner by the permissible substituents of organic compounds. Combinations of substituents and variables envisioned by this invention are preferably those that result in the formation of stable compounds useful in POSS-based compounds and/or coating applications. The term “stable”, as used herein, preferably refers to compounds which possess stability sufficient to allow manufacture and which maintain the integrity of the compound for a sufficient period of time to be detected and preferably for a sufficient period of time to be useful for the purposes detailed herein.

In some embodiments, an alkyl group has 1 to 3 carbon atoms (“C1-C3 alkyl”). In some embodiments, an alkyl group has 1 to 2 carbon atoms (“C1-C2 alkyl”). In some embodiments, an alkyl group has 1 carbon atom (“C1 alkyl”).
[00186] In some embodiments, an alkyl group has greater than or equal to 1 carbon atom. For example, in some embodiments, an alkyl group has greater than or equal to 1 carbon atom, greater than or equal to 2 carbon atoms, greater than or equal to 3 carbon atoms, greater than or equal to 4 carbon atoms, greater than or equal to 5 carbon atoms, greater than or equal to 6 carbon atoms, greater than or equal to 7 carbon atoms, greater than or equal to 8 carbon atoms, greater than or equal to 9 carbon atoms, or greater than or equal to 10 carbon atoms. In some embodiments, an alkyl group has less than or equal to 20 carbon atoms, less than or equal to 10 carbon atoms, less than or equal to 9 carbon atoms, less than or equal to 8 carbon atoms, less than or equal to 7 carbon atoms, less than or equal to 6 carbon atoms, less than or equal to 5 carbon atoms, less than or equal to 4 carbon atoms, less than or equal to 3 carbon atoms, or less than or equal to 2 carbon atoms. Combinations of the above recited ranges are possible (e.g., an alkyl group has greater than or equal to 1 carbon atom and less than or equal to 20 carbon atoms, an alkyl group has greater than or equal to 4 carbon atoms and less than or equal to 6 carbon atoms). Other ranges are also possible.
[00187] In some embodiments, an alkyl group has 1 to 6 carbon atoms (“C1-C6 alkyl”). Examples of C1-C6 alkyl groups include methyl (C1), ethyl (C2), n-propyl (C3), isopropyl (C3), n- butyl (C4), tert-butyl (C4), sec-butyl (C4), iso-butyl (C4), n-pentyl (C5), 3-pentanyl (C5), amyl (C5), neopentyl (C5), 3-methyl-2-butanyl (C5), tertiary amyl (C5), and n-hexyl (C6).

[00190] It should be understood that affixing the suffix “-ene” to a group indicates the group is a divalent moiety. For example, alkylene is the divalent moiety of alkyl (e.g., an acyclic carbon or a saturated acyclic carbon chain represented by the formula -CnH2n-), alkenylene is the divalent moiety of alkenyl (e.g., an acyclic carbon chain which contains a carbon-to-carbon double bond represented by the formula -CnH2n-2-), and alkynylene is the divalent moiety of alkynyl (e.g., an acyclic carbon chain which contains a carbon-to-carbon triple bond represented by the formula -CnH2n-4-). Affixing the suffice “-yne” to a group indicates the group is trivalent moiety (e.g., alkylyne is the trivalent moiety of alkyl, alkenylyne is the trivalent moiety of alkenyl, and alkynylyne is the trivalent moiety of alkynyl).
[00191] As used herein, the term “halogen” refers to fluorine (fluoro, -F), chlorine (chloro, -Cl), bromine (bromo, -Br), or iodine (iodo, -I).
[00192] As used herein, the term “hydroxy” or “hydroxyl” refers to an -OH group.

[00242] While several embodiments of the present invention have been described and illustrated herein, those of ordinary skill in the ail will readily envision a variety of other means and/or structures for performing the functions and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the present invention. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the teachings of the present invention is/are used. Those skilled in the art will recognize or be able to ascertain using no more than routine experimentation, many equivalents to the specific embodiments of the invention described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, the invention may be practiced otherwise than as specifically described and claimed. The present invention is directed to each individual feature, system, article, material, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, and/or methods, if such features, systems, articles, materials, and/or methods are not mutually inconsistent, is included within the scope of the present invention. [00243] In cases where the present specification and a document incorporated by reference include conflicting and/or inconsistent disclosure, the present specification shall control. If two or more documents incorporated by reference include conflicting and/or inconsistent disclosure with respect to each other, then the document having the later effective date shall control.
[00244] All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.
[00245] The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” [00246] The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified unless clearly indicated to the contrary. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A without B (optionally including elements other than B); in another embodiment, to B without A (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
[00247] As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or" as used herein shall only be interpreted as indicating exclusive alternatives (i.e., “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
[00248] As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
[00249] In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.
