A method of treating a biological tissue that enables dry storage of said tissue is disclosed. In one embodiment, the method comprises contacting the biological tissue with a non-aqueous treatment solution comprising a polyhydric alcohol and a C1-C3 alcohol and removing a portion of the treatment solution from the solution-treated biological tissue. Also disclosed is biological tissue prepared using the above process and prosthetic devices made with such tissue.

Disclosed is a method of producing hydrogen from oxygenated hydrocarbon reactants, such as methanol, glycerol, sugars (e.g. glucose and xylose), or sugar alcohols (e.g. sorbitol). The method takes place in the condensed liquid phase. The method includes the steps of reacting water and a water-soluble oxygenated hydrocarbon in the presence of a metal-containing catalyst. The catalyst contains a metal selected from the group consisting of Group VIIIB transitional metals, alloys thereof, and mixtures thereof. The disclosed method can be run at lower temperatures than those used in the conventional steam reforming of alkanes.

The disclosed inventions include microalgal biomass high in protein and fiber, wherein the biomass has been manufactured through heterotrophic fermentation. The materials provided herein are useful for the manufacture of meat substitutes and meat enhancers, as well as other food products that benefit from the addition of digestible protein and dietary fiber. Structural properties of foods are enhanced through the use of such materials, including texture and water retention properties. High in protein and fiber food materials of the invention can be manufactured from edible and inedible heterotrophic fermentation feedstocks, including corn starch, sugar cane, glycerol, and depolymerized cellulose.

The invention relates to a gel pad and a uv-curing production method thereof. This invention, including the gel bag, is characterized in that the gel bag is filled with gel which is prepared from gel monomers, a cross-linking agent and a photoinitiatorandwater prepared from the UV curving. The gel consists of monomers, cross-linking agents, cross-linking agents, photo initiators and water. The said monomer are two or more than two of an acrylic acid alkali metal salt, ester generated by methacrylic acid ,acrylamide ,methacrylamide and AMPS(2-acrylamide-2-methyl-propanesulfonic acid ). The said cross-linking agent is a non-conjugated double bond compound which is polyol(glycerol )N,N'-methylene bisacrylamide. The said photoinitiator is a cracking type initiator or a photosensitive initiator or a cationic initiator. The advantages of the method are that the production process is simple, the gel solidification is fast and the gel pad produced is flattened.

Porous polymeric membranes including Halar (poly (ethylene chlorotrifluoroethylene)) and related compounds and the methods of production thereof which avoid the use of toxic solvents. Preferred solvents, coating agents and pore forming agents are citric acid ethyl ester or glycerol triacetate. The membranes may be in the form of a hollow fiber or flat sheet, and may include other agents to modify the properties of the membrane, such as the hydrophilic / hydrophobic balance. Leachable agents may also be incorporated into the membranes.

Synthetic absorbable sutures are filled with a stabilizing agent, preferably a mixture of glycerol and calcium lactate, and inserted into a retainer having a narrow convoluted passageway. The retainer is inserted into an open foil pouch with a package stabilizing element such as a paper sheet filled with stabilizing agent. The package containing the suture, retainer and package stabilizing element is sterilized, aerated, equilibrated to a relatively high moisture level, and sealed. Long lengths of suture and doubled-over and tripled-over suture may be withdrawn from the retainer with low force without damaging the suture. Bends and kinks in the suture are prevented so as to provide a synthetic absorbable suture having highly desirable out of package hand and feel. The suture an removed from the package exhibits improved tissue drag characteristics.

A triglyceride-to-fuel conversion process including the steps of (a) preconditioning unsaturated triglycerides by catalytic conjugation, cyclization, and cross-link steps; (b) contacting the modified triglycerides with hot-compressed water containing a catalyst, wherein cracking, hydrolysis, decarboxylation, dehydration, aromatization, or isomerization, or any combination thereof, of the modified triglycerides produce a crude hydrocarbon oil and an aqueous phase containing glycerol and lower molecular weight molecules, and (c) refining the crude hydrocarbon oil to produce various grades of biofuels. A triglyceride-to-fuel conversion process further including the steps of (a) carrying out anaerobic fermentation and decarboxylation / dehydration, wherein the anaerobic fermentation produces hydrogen, volatile acids, and alcohols from fermentable feedstocks, and the decarboxylation / dehydration produces alkenes from the volatile acids and alcohols, respectively; (b) feeding the alkenes to the cyclization process; (c) feeding the hydrogen to the post refining process; and (d) recycling the aqueous phase containing glycerol to the decarboxylation / dehydration process. A biofuel composition including straight-chain, branched and cyclo paraffins, and aromatics. The paraffins are derived from conversion of triglycerides. The aromatics are derived from conversion of either triglycerides, petroleum, or coal.

Deicing compositions comprised of glycerol-containing by-products of triglyceride processing processes are disclosed.
