PREPARATION OF CHITIN NANOCRYSTALS AND NANOWHISKERS FROM CRUSTACEAN BIOMASS USING IONIC LIQUID CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Application Serial No. 63/253,307, filed October 7, 2021, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD OF THE INVENTION [0002] The present invention relates in general to the field of preparing chitin nanocrystals and/or nanowhiskers (chitin derivatives that differ in dimensions), and more particularly, to a novel method for preparing chitin nanocrystals and nanowhiskers from chitinous biomass using ionic liquids in a single step. STATEMENT OF FEDERALLY FUNDED RESEARCH [0003] None. BACKGROUND OF THE INVENTION [0004] Without limiting the scope of the invention, its background is described in connection with chitin. Chitin nanocrystals and nanowhiskers are derivatives of chitin and are typically obtained through acid hydrolysis of chitin. [0005] Chitin. Chitin is one of the main components in the exoskeleton of shellfish. Wastes from crab, lobster, crayfish, shrimp, and krill are the most important source of chitin. Chitin is also present in insects and cell walls of fungi, ² skeleton of sponges, inner skeleton of squid and cuttlefish, mushrooms, and insects (such as fly larvae). In crustacean biomass, chitin content ranges between 8 and 40%, ¹ in mushrooms chitin content is less than 20%, and in insects up to 20%. Chitin is a linear polysaccharide, and the second most abundant natural polymer after cellulose. ³ This natural polymer is made of N-acetyl-D-glucose-2-amine units that are linked together in β-1,4 manner. Native chitin is highly crystalline and occurs in three forms that depend on its origin and are identified as α-, β- and γ-chitin. Chitin from shrimp shells is α-form. In both α- and β- forms, the chitin chains are organized in sheets where they are tightly held by a number of intra-sheet hydrogen bonds, but in α-chitin, all chains are arranged in an antiparallel fashion. ^5,6 [0006] The various forms of chitin can be differentiated by powder X-ray diffraction (pXRD) technique, Fourier-Transform Infrared Spectroscopy (FTIR), and Solid-state Cross-Polarization Magic Angle Spinning Carbon-13 Nuclear Magnetic Resonance (CP/MAS – NMR) Spectroscopy. ⁷ Hierarchical fibrillar structure of chitin is as follows: at the molecular level it is the polymeric chain, and arrangement of 18–25 of such chains in the form of narrow and long crystalline units form nanofibrils with a diameter ranging from 2.5 to 2.8 nm and about 300 – 500 nm length. These nanofibrils are clustered into chitin–protein microfibrils of about 25–300 nm in diameter. ⁸ In crustacean biomass, the matrix that surrounds chitinous tissues contains proteins and is extensively mineralized (e.g., crustacean shells), whereas in insect biomass chitin exist with proteins, and in mushrooms chitin co-exists with glucans. [0007] In industrial processing, chitin is extracted from chitinous biomass by alkaline treatment (deproteinization) to solubilize proteins and by acid treatment (demineralization) to dissolve minerals. ⁹ Sometimes, a decolorization is also carried out to remove astaxanthin pigment. Ionic liquids are also used for isolation of pure chitin using a series of extraction steps (i.e., with 1-ethyl- 3-methylimidazolium acetate [C ₂ mim][OAc]). The chitin derivative, chitosan, is a deacetylated form of chitin produced by reflux of chitin in excess sodium hydroxide aqueous solution. ² Thus, it is a linear polysaccharide composed of randomly distributed β-(1,4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). Chitosan it is not relevant to the present invention. [0008] Ionic liquids thus far have been used for dissolution of chitin (i.e., as solvents for chitin), ¹⁵ and extraction of chitin through solubilization of the polymer in ionic liquids. These so-called “dissolving” ILs (see, e.g., U.S. Patent Publication No.20190040209) are used for the isolation of purified chitin polymer, but not for formation of nanocrystals and nanowhiskers. If chitin is solubilized, the prepared solutions subsequently enable the products technology platform based on “solution processing” (shaping chitin solutions into different materials). ^16-23 For dissolution of chitin to occur, this hydrogen bonding network of the polymer first needs to get disrupted. [0009] Another type of ILs is so-called “pulping” ILs (Patent No. 10,100,131) that are used to isolate chitin polymer. [0010] The only art uses the formation of nanowhisker-films (not individual whiskers) from purified chitin using 1-allyl-3-methylimidazolium bromide IL, ²⁴ prepared through initial dissolution of chitin, coagulation with methanol, and formation of gels. This dissolution method utilizes pure chitin polymer, and not biomass. [0011] Preparation of Chitin Nanowhiskers from Purified Chitin. The preparation of chitin nanofibers or nanocrystals and nanowhiskers from the complex hierarchy of chitinous biomass involves various steps. Chitin does not occur alone in living organisms, but always coexists with some other compounds. As opposed to cellulose, where two other components of biomass, hemicellulose and lignin (which are also polymeric by nature and can easily undergo hydrolysis simultaneously with cellulose), chitinous biomass contains proteins and (often but not always) minerals, that must be removed prior to making nanocrystals and nanowhiskers. At present, the major sources of chitin in industry are the shell wastes of crabs and shrimps. The shell wastes are mainly made up of chitin (20−30%), proteins (30−40%), calcium carbonate (30−50%), and lipids and astaxanthin (<1%). ²⁵ Overall process for preparation of chitin from shell wastes usually includes four main steps, as shown in FIG.1B (Prior Art), which requires: (1) removal of proteins with dilute NaOH (deproteinization), (2) removal of minerals in dilute HCl (demineralization), (3) extraction of astaxanthin and lipids with organic solvents such as acetone and ethanol (decolorization), and often (4) bleaching with NaClO to obtain purified chitin. The purified chitin can be used in preparation of suspension of chitin whiskers in strong acid aqueous medium. [0012] Therefore, all methods include the preparation of purified chitin prior to preparation of nanocrystals and nanowhiskers. The extra step of chitin isolation adds cost and thus for practical commodity materials and applications, it would be advantageous to be able to conduct preparation of nanocrystals and nanowhiskers directly from the original chitinous biomass. There are few reports where nanocrystals and nanowhiskers seem to be produced from biomass (see a Table from reference [26]), however, the thorough analysis revealed that purified chitin was first isolated prior ChNCs preparation in all reported cases (Table 1), and from the biomass source was provided, to distinguish between chitins of different origins. Obtained chitin was processed by acid hydrolysis, TEMPO, or other types (i.e., periodinate) of oxidations. There are many cases of chitin nanowhiskers production in literature and Table 1 is, by no means, an exhaustive and/or complete list of reported methods, but rather provides few representative examples.

Before preparing chitin nanocrystals and nanowhiskers, chitin has to be isolated or extracted from biomass. 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation: Chitin nanocrystals and nanowhiskers were also prepared from pure chitin by 2,2,6,6- tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation of α-chitin in water at pH 10. Periodate-anions mediated oxidation: For isolating nanocrystals and nanowhiskers from chitin- containing starting material (chitin is used in the example) chitin was exposed to an oxidative effect of periodate anions in an aqueous suspension with pH > 7.0, for a period of at least one day (in the actual patent 60% yield was obtained after 30 days). Persulfate oxidation: ^{Error! Bookmark not defined.} Chitin flakes are oxidized by ammonium persulfate oxidant with vigorous stirring. Deep Eutectic Solvents (DES): Alpha α-chitin from shrimp shells, betaine hydrochloride and ferric chloride hexahydrate are continuously mixed to prepare DES, chitin is added in, and heated. [0014] Despite these advancements, a need remains for novel methods for making chitin nanocrystals and nanowhiskers.

DETAILED DESCRIPTION OF THE INVENTION [0057] While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention. [0058] To facilitate the understanding of this invention, a number of terms are defined below. Terms defined herein have meanings as commonly understood by a person of ordinary skill in the areas relevant to the present invention. Terms such as “a”, “an” and “the” are not intended to refer to only a singular entity, but include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments of the invention, but their usage does not delimit the invention, except as outlined in the claims. [0059] Provided herein are methods related to chitin nanocrystals and nanowhiskers and particularly, but not exclusively, to methods for producing individual chitin nanocrystals and nanowhiskers from biomass, without prior isolation of raw chitin polymer using ionic liquid. The resulting chitin nanocrystals and nanowhiskers comprise a high aspect ratio, are highly crystalline, and of high thermal stability. The method also stands out due to a high, >70% yield based on amount of chitin present in biomass. In certain aspect, the present invention includes the isolation of purified chitin nanocrystals and nanowhiskers with a 30, 40, 50, 55, 60, 65, 70, 75, 79, 80 or greater percent yield. [0060] As used herein, the term “ionic liquids” refers to compounds that contain ionized species (i.e., cations and anions) that generally have a melting point below about 100°C. The anionic components in the mixture can be the same or different. Examples of ionic liquids are organic salts containing one or more cations that are typically ammonium, imidazolium, or pyridinium ions; although, many other types are known and disclosed herein. When referring to ionic liquid mixtures, these are crude ionic liquids. and can contain impurities such as solvent or water. [0061] Properties of ionic liquids are high liquid range, non-volatility, non-flammability, high thermal stability. For a review of ionic liquids see, for example, Welton, Chem Rev., 99, 2071- 2083, 1999. Ionic Liquids. Ionic liquids (ILs, organic salts with melting points below 100 °C ¹² ) are special class of solvents. IL technologies of biomass processing in general, and chitin processing in particular, have built an enormous quantity of technical reports (for recent reviews, please see: Silva et al. ¹³ and Jaworska et al. ¹⁴ ). [0062] Ionic liquids can be impure and include solvent molecules in the amount for example, <10 %, <5.0%, <4.0%, <3.0%, <2.0%, or <.01%, however, these solvent molecules are not required to be present in order to form the ionic liquids. The solvent molecules might include water-soluble alcohols, ketones or aldehydes such as ethanol, methanol, 1- or 2-propanol, tert-butanol, acetone, methyl ethyl ketone, acetaldehyde, propionaldehyde, ethylene glycol, propylene glycol, dimethyl sulfoxide, dimethyl formamide, acetamide, hexamethyl phosphoramide, N-Methylmorpholine N- oxide (NMMO), the C ₁ -C ₆ alkyl and alkoxy ethylene glycols and propylene glycols such as 2- methoxyethanol, 2-ethoxyethanol, 2-butoxyethanol, diethyleneglycol, and the like. [0063] Chitin Nanowhiskers. Chitin nanocrystals and nanowhiskers are high performance nanomaterials that can be prepared from purified chitin. They are rod- or whisker-shaped particles that have dimensions selected from: 5–20 nm in width, 50–500 nm in length, and/or a high aspect ratio (10–100) depending on the source. ¹⁰ In suspension, ChNCs tend to aggregate into irregular shapes with a wide particulate distribution ranging from 20 to 2,000 nm. They are different from chitin nanofibers (ChNFs) that have a diameter of about 5 – 20 nm but lengths in the micron scale. The particle size of ChNCs is one of the principal parameters that influences all properties of these nanoscale materials and determines their diffusivity, viscosity in a solution, uniformity, and chirality. Chitin nanowhiskers have been emerging as sustainable materials with unique properties like high aspect ratio, high modulus (200 GPa ¹¹ ), stiffness, strength, non-toxicity, biodegradability, crystallinity, biocompatibility, high binding energy and liquid-crystalline behavior. As a rigid whisker-shaped nanomaterial, ChNWs are an ideal candidate for preparing nanocomposites as reinforcement materials for different polymeric matrices. ChNCs have a high potential in production of regenerative and bio-degradable materials in various technical fields. [0064] Present Invention. Provided herein is a technology related to chitin nanocrystals and nanowhiskers and particularly, but not exclusively, to methods for producing individual chitin nanocrystals and nanowhiskers from biomass, without prior isolation of raw chitin polymer using ionic liquid. The resulting chitin nanocrystals and nanowhiskers comprise a high aspect ratio, are highly crystalline, and of high thermal stability. The method also stands out due to a high, 70% yield based on amount of chitin in biomass. [0065] Biomass. As used herein, the term “chitinous biomass” means any source of chitin derived from marine or anthropod exoskeleton, squid pen, fungi, mushrooms, etc. Non-limiting examples of biomass include the shells of crustaceans: shrimp, crab, crawfish, prawns, lobster biomass, squid pen, fly larvae, or a mixture thereof. When the biomass is a chitin-containing biomass, the biomass can be any biomass either in a processed, derivatized, pure, or impure form. In a preferred aspect the biomass is a crustacean biomass. [0066] Ionic Liquid. In this process, ILs act as a hydrolyzing agent. For the purpose, strongly “Brönsted Acidic Ionic Liquids” are suitable. ³⁹ An acidic IL can be defined as a low melting ionic salt with acidic characteristics of Brönsted type. A “Bronsted acid” is an acidic compound capable of donating a proton to an appropriate base. ILs may contain one or more types of cations and one or more types of anions, which are described below. The acidic function(s) or group(s) can be either in the cation, anion, or both. [0067] As used herein, the term “protic ionic liquid” describes an ionic liquid formed by the protonation of a base with a Bronsted acid to form a salt. In turn, a “Brönsted acid” is an acidic compound capable of donating a proton to an appropriate base. [0068] Anion: An anion for a contemplated ionic liquid cation can be Bronsted-acidic anion. the acidic IL with [RSO ₄ ]- -anion, where R = C1-C6 alkyl or a C1-C6 alkoxyalkyl group, or substituted alkyl/ alkoxyalkyl the acidic IL with [RSO3]- - anion, where R = C1-C6 alkyl or a C1-C6 alkoxyalkyl group, or substituted alkyl/ alkoxyalkyl the acidic IL with [H ₂ PO ₄ ]- -anion; the acidic IL with [R1R2PO4]- -anion, where R1 and R2 = independently C1-C6 alkyl or a C1-C6 alkoxyalkyl group, or substituted alkyl/ alkoxyalkyl [0069] Cations Imidazolium or substituted imidazolium Ammonium or substituted ammonium Pyridinium or substituted pyridinium Brönsted Acidic Ionic Liquids with Acidic Hydrogens on a Functional Group alkane sulfonic acid group —SO ₃ H is covalently tethered to the IL cation Examples (can be any cation mentioned below) Protic Acidic Ionic Liquids with Acidic Hydrogens on Cation and Anion Combinations of anything from above [0070] Example 1: [0071] Shrimp shells were ground, sieved to < 150 µm, and dried in the oven at 50°C overnight. Ionic liquid 1-butyl-3-methylimidazoulim hydrogen sulfate [C4mim][HSO4] (48.5 g) was added to 1.5 g chitinous biomass, the obtained paste thoroughly mixed, capped, wrapped with parafilm and left for 48 h. After 48 hours, water was added to the reactions (16.7 mL). When water was added, the reaction produced large amount of foam. Reaction was subjected to 110°C heating in oil bath, for another 48 hours, then quenched with 50 mL water. The solution was poured into beaker, more water added (50 mL water), resulting suspension was mixed, transferred into test tubes, and centrifuged (Eppendorf 5430 R, rotor CE 11017, 7830 rpm). The precipitate was repeatedly washed through several water addition-centrifugation cycles (water decanted, 2x45 mL fresh water added, particles dispersed and suspension centrifuged) until pH 6-7 (total 6 cycles). The resulting suspension was ultrasonicated with 30 second cycles, for overall 10 min. To quantify the amount of ChNCs, half of the suspension was freeze-dried. Yield of chitin-nanocrystals and nanowhiskers 79% was obtained. [0072] Example 2 [0073] Crab and lobster shells (mixture) were ground, sieved to < 150 µm, and dried in the oven at 50°C overnight. Ionic liquid 1-butyl-3-methylimidazoulim hydrogen sulfate [C4mim][HSO4] (48 g) was added to 2 g chitinous biomass, the obtained paste thoroughly mixed, capped, wrapped with parafilm and left for 48 h. After 48 h, water was added to the reactions (16 mL). When water was added, the reaction produced large amount of foam. The reaction was subjected to 110°C heating in oil bath, for another 48 h, then quenched with 50 mL of water. The solution was poured into beaker, more water added (50 mL water), the resulting suspension was mixed, transferred into test tubes, and centrifuged (Eppendorf 5430 R, rotor CE 11017, 7830 rpm). The precipitate was repeatedly washed through several water addition-centrifugation cycles (water decanted, 2x45 mL fresh water added, particles dispersed and suspension centrifuged) until pH 6-7 (total 6 cycles). The resulting suspension was ultrasonicated with 30 s cycles, for overall 10 min. To quantify amount of ChNCs, half of the suspension was freeze-dried. Yield of chitin-nanocrystals and nanowhiskers 81% was obtained. [0074] Example 3 [0075] Dried mushrooms were ground, sieved to < 150 µm, and dried in the oven at 50°C overnight. Ionic liquid 1-butyl-3-methylimidazoulim hydrogen sulfate [C4mim][HSO4] (48 g) was added to 2 g mushroom biomass, the obtained paste thoroughly mixed, capped, wrapped with parafilm and left for 24 h. After 24 h, water was added to the reactions (14 mL). No foam was formed. The reaction was subjected to 100°C heating in oil bath, for 24 h, then quenched with 40 mL of water. The solution was poured into beaker, more water added (50 mL water), the resulting suspension was mixed, transferred into test tubes, and centrifuged (Eppendorf 5430 R, rotor CE 11017, 7830 rpm). The precipitate was repeatedly washed through several water addition- centrifugation cycles (water decanted, 2x45 mL fresh water added, particles dispersed and suspension centrifuged) until pH 6-7 (total 6 cycles). The resulting suspension was ultrasonicated with 30 s cycles, for overall 10 min. The suspension was freeze-dried.

FIG. 3 is a High-Resolution Atomic Force Microscopy (AFM) Topography Image (Asylum Research MFP- 3D™, 5 µm scale) of chitin nanocrystals and nanowhiskers obtained from shrimp shell biomass. FIG. 4 is a High-Resolution Atomic Force Microscopy (AFM) Topography Image (Asylum Research MFP-3D™, 2.5 µm scale) of chitin nanocrystals and nanowhiskers obtained from shrimp shell biomass. [0077] FIG. 5 shows a Fourier transform infrared spectra (FTIR) of shrimp shell biomass (red), commercial chitin (green) and chitin nanowhiskers (blue) obtained from shrimp shell biomass. FIG.6 shows a Fourier transform infrared spectra (FTIR) of crab and lobster mixed biomass (red), commercial chitin (green) and chitin nanowhiskers (blue) obtained from crab and lobster mixed biomass. FIG. 7 shows a Powder X-ray diffraction (PXRD) of shrimp shell biomass (red), commercial chitin (green) and chitin nanowhiskers (blue) obtained from shrimp shell biomass. FIG.8 shows a Powder X-ray diffraction (PXRD) of shrimp shell biomass (red), commercial chitin (green) and chitin nanowhiskers (blue) obtained from crab and lobster mixed biomass. [0078] Thus, the present invention allows formation of chitin nanowhiskers directly from biomass, allows making nanowhiskers in a single step, eliminates use of hydrochloric acid from chemical synthesis, and/or eliminates hazardous solvents from chemical synthesis. The method taught herein does not require prior isolation of chitin from crustacean biomass, and is a “green” method that does not use hazardous solvents. [0079] Further, the present invention obtains chitin nanowhiskers without the use of hydrolysis with using strong acids (e.g., 2.5 - 4 N hydrochloric acid), TEMPO-mediated oxidation; ultrasonication; and/ or mechanochemistry. One of more of these methods causes mechanical damage to the chitin nanowhiskers, has a reduced yield, and requires the use of more than one step for the isolation of the chitin nanowhiskers. [0080] It is contemplated that any embodiment discussed in this specification can be implemented with respect to any method, kit, reagent, or composition of the invention, and vice versa. Furthermore, compositions of the invention can be used to achieve methods of the invention. [0081] It will be understood that particular embodiments described herein are shown by way of illustration and not as limitations of the invention. The principal features of this invention can be employed in various embodiments without departing from the scope of the invention. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, numerous equivalents to the specific procedures described herein. Such equivalents are considered to be within the scope of this invention and are covered by the claims. [0082] All publications and patent applications mentioned in the specification are indicative of the level of skill of those skilled in the art to which this invention pertains. All publications and patent applications are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. [0083] The use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.” The use of the term “or” in the claims is used to mean “and/or” unless explicitly indicated to refer to alternatives only or the alternatives are mutually exclusive, although the disclosure supports a definition that refers to only alternatives and “and/or.” Throughout this application, the term “about” is used to indicate that a value includes the inherent variation of error for the device, the method being employed to determine the value, or the variation that exists among the study subjects. [0084] As used in this specification and claim(s), the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”) or “containing” (and any form of containing, such as “contains” and “contain”) are inclusive or open- ended and do not exclude additional, unrecited elements or method steps. In embodiments of any of the compositions and methods provided herein, “comprising” may be replaced with “consisting essentially of” or “consisting of”. As used herein, the phrase “consisting essentially of” requires the specified integer(s) or steps as well as those that do not materially affect the character or function of the claimed invention. As used herein, the term “consisting” is used to indicate the presence of the recited integer (e.g., a feature, an element, a characteristic, a property, a method/process step or a limitation) or group of integers (e.g., feature(s), element(s), characteristic(s), propertie(s), method/process steps or limitation(s)) only. [0085] The term “or combinations thereof” as used herein refers to all permutations and combinations of the listed items preceding the term. For example, “A, B, C, or combinations thereof” is intended to include at least one of: A, B, C, AB, AC, BC, or ABC, and if order is important in a particular context, also BA, CA, CB, CBA, BCA, ACB, BAC, or CAB. Continuing with this example, expressly included are combinations that contain repeats of one or more item or term, such as BB, AAA, AB, BBC, AAABCCCC, CBBAAA, CABABB, and so forth. The skilled artisan will understand that typically there is no limit on the number of items or terms in any combination, unless otherwise apparent from the context. [0086] As used herein, words of approximation such as, without limitation, “about”, "substantial" or "substantially" refers to a condition that when so modified is understood to not necessarily be absolute or perfect but would be considered close enough to those of ordinary skill in the art to warrant designating the condition as being present. The extent to which the description may vary will depend on how great a change can be instituted and still have one of ordinary skilled in the art recognize the modified feature as still having the required characteristics and capabilities of the unmodified feature. In general, but subject to the preceding discussion, a numerical value herein that is modified by a word of approximation such as “about” may vary from the stated value by at least ±1, 2, 3, 4, 5, 6, 7, 10, 12 or 15%. [0087] Additionally, the section headings herein are provided for consistency with the suggestions under 37 CFR 1.77 or otherwise to provide organizational cues. These headings shall not limit or characterize the invention(s) set out in any claims that may issue from this disclosure. Specifically, and by way of example, although the headings refer to a “Field of Invention,” such claims should not be limited by the language under this heading to describe the so-called technical field. Further, a description of technology in the “Background of the Invention” section is not to be construed as an admission that technology is prior art to any invention(s) in this disclosure. Neither is the “Summary” to be considered a characterization of the invention(s) set forth in issued claims. Furthermore, any reference in this disclosure to “invention” in the singular should not be used to argue that there is only a single point of novelty in this disclosure. Multiple inventions may be set forth according to the limitations of the multiple claims issuing from this disclosure, and such claims accordingly define the invention(s), and their equivalents, that are protected thereby. In all instances, the scope of such claims shall be considered on their own merits in light of this disclosure, but should not be constrained by the headings set forth herein. [0088] All of the compositions and/or methods disclosed and claimed herein can be made and executed without undue experimentation in light of the present disclosure. While the compositions and methods of this invention have been described in terms of preferred embodiments, it will be apparent to those of skill in the art that variations may be applied to the compositions and/or methods and in the steps or in the sequence of steps of the method described herein without departing from the concept, spirit and scope of the invention. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope and concept of the invention as defined by the appended claims. [0089] To aid the Patent Office, and any readers of any patent issued on this application in interpreting the claims appended hereto, applicants wish to note that they do not intend any of the appended claims to invoke paragraph 6 of 35 U.S.C. § 112, U.S.C. § 112 paragraph (f), or equivalent, as it exists on the date of filing hereof unless the words “means for” or “step for” are explicitly used in the particular claim. [0090] For each of the claims, each dependent claim can depend both from the independent claim and from each of the prior dependent claims for each and every claim so long as the prior claim provides a proper antecedent basis for a claim term or element.
