摘要:
An improved cell culture monitoring system and method that detects cell growth and concentration in a dynamic environment of incubator/shaker. In order to reduce power consumption and make a wireless cell culture monitoring system practical, several methods of temperature compensation are used to replace a method of controlling the temperature of sensing module. Furthermore its power consumption can be significantly reduced by using an adaptive and synchronized light pulse detection technique.
摘要:
This application describes a novel technology in drug discovery and drug-based imaging/detection: the wrapping technology. This technology is based on identified singularities in the structure of soluble proteins. In contrast with drug-design approaches based on standard structural considerations, the packing of a protein, or more precisely, its dehydron pattern, may be used as a selectivity filter to design small-molecule inhibitors. The wrapping technology described herein is a novel form of rational drug design for avoiding side effects in drug therapy and sharpening the inhibitory impact of drugs on the oncokinome.

The disclosure relates to catalytically active carbocatalysts, e.g., a graphene oxide or graphite oxide catalyst suitable for use in a variety of chemical transformations. In one embodiment, it relates to a method of catalyzing a chemical reaction of an organic molecule by reacting the organic molecule in the presence of a sufficient amount of graphene oxide or graphite oxide for a time and at a temperature sufficient to allow catalysis of a chemical reaction. According to other embodiments, the reaction may be an oxidation reaction, a hydration reaction, a dehydrogenation reaction, a condensation reaction, or a polymerization reaction. Some reactions may include auto-tandem reactions. The disclosure further provides reaction mixtures containing an organic molecule and graphene oxide or graphite oxide in an amount sufficient to catalyze a reaction of the organic molecule.
摘要:
A fiber is obtainable from or comprises an ethylene/α-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re>1481−1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven or non-woven fabrics can be made from such fibers.

This invention relates to polyolefin compositions. In particular, the invention pertains to elastic polymer compositions that can be more easily processed on cast film lines, extrusion lamination or coating lines due to improved resistance to draw resonance. The compositions of the present invention preferably comprise an elastomeric polyolefin resin and a high pressure low density type resin.
摘要:
Described herein are composite compositions and methods for making such compositions. The composition includes or is the reaction product of a cellulosic material, an organic component, and a thermoplastic. Some useful organic components include a silane-containing polymer. Some of the compositions have improved physical properties such as tensile properties, improved strength, and reduced water absorption.
摘要:
The present invention provides a bicomponent fiber having increased surface roughness. The fiber includes a first polymer and a composite, wherein the composite forms a layer which forms at least a portion of the fiber's surface. The composite is formed by a second polymer and a filler, where an average particle size of the filler can be greater than a thickness of the layer formed by the composite. The fibers can have a round, oval, trilobal, triangular, dog-boned, flat or hollow shape and a symmetrical or asymmetrical sheath/core or side-by-side configuration. When the fiber has a sheath/core configuration, the composite can form the sheath, and the average particle size of the filler can be greater than the thickness of the sheath.
