摘要:
A library of materials is screened for mechanical properties such as strength, tack or other properties. A library of materials is provided. A stimulus such as a stress or force is provided to each member of the library. A response (e.g., a strain) of each of the materials due to the stimulus is measured and the response, the stimulus or both are recorded and related to provide data. Thereafter, the data is analyzed to reach conclusions regarding properties of the material samples.

摘要:
A method for evaluating a test fluid as a fabric care composition or as a component thereof. The method includes providing a test sheet of fabric comprising a plurality of test regions and simultaneously contacting each of the plurality of test regions with a different test fluid. The method further includes screening the plurality of test regions or the contacted test fluids for a fabric property of interest to evaluate the relative efficacy of the different test fluids.
摘要:
A sensor-array based materials characterization apparatus for characterizing one or more material properties of at least five test samples, wherein the apparatus includes a sensor array disposed on a substrate; electronic test circuitry for sending electrical signals to and receiving electrical signals from the sensor array; electronic circuitry for routing signals between selected sensors and the electronic test circuitry; and a computer or processor electrically coupled to electronic test circuitry and electronic circuitry.
摘要:
Methods of nanometer pattern formation and transfer onto a selected substrate are provided wherein a selected block copolymer is coated onto the selected substrate and a component of the block copolymer is chemically modified or physically removed so that the dense periodic pattern of the block copolymer can be transferred onto the selected substrate. Substrates prepared by these methods are also provided.
摘要:
The present invention provides crosslinked amine polymers effective for binding and removing bile salts from the gastrointestinal tract. These bile acid binding polymers or pharmaceutical compositions thereof can be administered to subjects to treat various conditions, including hypercholesteremia, diabetes, pruritus, irritable bowel syndrome-diarrhea (IBS-D), bile acid malabsorption, and the like.
摘要:
The present invention provides methods and compositions for the treatment of ion imbalances using core-shell composites and compositions comprising such core-shell composites. In particular, the invention provides core-shell particles and compositions comprising potassium binding polymers, and core-shell particles and compositions comprising sodium binding polymers, and in each case, pharmaceutical compositions thereof. Methods of use of the polymeric and pharmaceutical compositions for therapeutic and/or prophylactic benefits are also disclosed. The compositions and methods of the invention offer improved approaches for treatment of hyperkalemia and other indications related to potassium ion homeostasis, and for treatment of hypertension and other indicates related to sodium ion homeostasis.
摘要:
The present invention is directed to crosslinked cation exchange polymers comprising a fluoro group and an acid group, pharmaceutical compositions of these polymers, compositions of a linear polyol and a salt of such polymer. Crosslinked cation exchange polymers having beneficial physical properties, including combinations of particle size, particle shape, particle size distribution, viscosity, yield stress, compressibility, surface morphology, and/or swelling ratio are also described. These polymers and compositions are useful to bind potassium in the gastrointestinal tract.
