COATED BIOLOGICAL COMPOSITION
A coated biological composition has a mixture of biologic material and a volume of a liquid protectant. The mixture of biologic material has non-whole cellular components or whole cells or combinations of the non-whole cellular components and whole cells, wherein the mixture is compatible with biologic function. The volume of a liquid protectant is intermixed with the mixture of biologic material, wherein the liquid protectant forms a coating externally enveloping each of the non-whole cellular components, if any, and each of the whole cells, if any, of the mixture of biologic material, to form the coated biological composition. The coated biological composition is frozen and thereafter thawed and then frozen a second time for storage or frozen at least once and thawed and stored under refrigeration above freezing, or frozen and thawed and then concentrated by drying, or while frozen without thawing lyophilized for ambient or room temperature storage.
Alkaline pH-modified edible casein-based films and coatings, and method for the making thereof
Improved casein-based films are produced by adjusting the pH of a film-production suspension. The film-production suspension may contain a casein source, a plasticizer, and optionally a strengthening additive. The adjustment of the pH may be accomplished by the addition of an alkaline additive, such as a base, to achieve a desired pH value. The improved casein-based films have improved physical properties as compared to those produced without a pH-adjusted film-production suspension at least in part due to the chemical and structural changes imparted by the change in pH.
USE OF NANOPOROUS CARBON MEMBRANES FOR SEPARATING AQUEOUS/ORGANIC MIXTURES
The invention relates to the extraction of organic compounds from mixtures of said compounds with water, using a nanoporous carbon membrane. The invention can be used in any field where it is desired to separate an organic compound of interest from water, such as the drying of alcohols or alkanes.

Method for separating and washing of microparticles via a stratified coflow of non-Newtonian and Newtonian fluids
The present invention relates to a method for separating and washing microparticles via a stratified co-flow of non-Newtonian fluid and Newtonian fluid, wherein the Newtonian fluid as well as the non-Newtonian fluid may flow into a transfer channel formed in a fluid chip at a predetermined flow rate ratio matching with an effective diameter of the target particles contained in the non-Newtonian fluid, thereby inducing a change in positions of particle focusing points with respect to the target particles within the stratified co-flow thereof formed in the transfer channel. As a result, it is possible to more easily separate only the target particles among the microparticles contained in the non-Newtonian fluid toward the Newtonian fluid without using an additional device and human power, or transfer the target particles contained in the non-Newtonian fluid toward the Newtonian fluid for washing the same. Accordingly, since native biofluids used in the studies and clinical experiments are mostly non-Newtonian fluid, it is possible to directly separate and wash the target particles without a need of changing a solution for containing cells/particles or additional diluting the same for executing experiments. If the native biofluids as the non-Newtonian fluid lack a relaxation time, any artificial polymer could be simply added thereto in order to increase the relaxation time, thereby greatly increasing an amount of treatment per time. Further, since high working efficiency can be achieved in a wide range of flow rate, high efficient separation and washing processes may be achieved by a simple hand work of pushing and pumping an injector alone, without any accurate pumping device.
STABILIZATION OF POLYHYDRIC ALCOHOLS BY STEAM INJECTION
A method for separating monoethylene glycol (MEG) from one or more oxygenates. The method includes providing a stream comprising MEG and one or more oxygenates to a distillation column, providing a water feed stream to a bottom of the distillation column, and removing a recovery stream comprising MEG from the distillation column. The distillation column is operated at higher temperatures than the thermal stability of MEG and the one or more oxygenates.
Fatty glyceride preparation method
The present invention provides a fatty glyceride preparation method, comprising converting fatty acid short-chain alcohol ester into fatty glyceride basic mixture by sequentially carrying out a normal-pressure reaction and a vacuum reaction in the nitrogen condition in the temperature of 80 C. to 150 C.; and meanwhile adding a basic catalyst and glycerin or adding a basic catalyst and a glycerin derivative into the fatty acid short-chain alcohol ester, so as to implement a conversion from the fatty acid short-chain alcohol ester to the fatty glyceride. Conditions of the preparation method are relatively moderate, and the structure of the fatty acid is not damaged in the reactions; the yield of the glyceride is high, compositions of the glyceride are stable and controllable, glyceride products having a high content of triacylglycerol can be obtained; the process is simple, costs are low, and the fatty glyceride is applicable to industrial production.
Process for recovery of glycerol from biodiesel production streams
The present invention relates to a process for treating a glycerol solution comprising fatty acid soaps obtained in a biodiesel production process, to obtain a glycerol enriched phase.

Oxopiperazine helix mimetics for control of Hypoxia-Inducible gene expression
The present invention relates to oxopiperazines that mimic helix B of the C-terminal transactivation domain of HIF1. Also disclosed are pharmaceutical compositions containing these oxopiperazines and methods of using these oxopiperazines (e.g., to reduce gene transcription, treat or prevent disorders mediated by interaction of HIF1a with CREB-binding protein and/or p300, reduce or prevent angiogenesis in a tissue, induce apoptosis, and decrease cell survival and/or proliferation).
