This disclosure provides systems, methods, and apparatus related to thermoelectric polymer aerogels. In one aspect, a method includes depositing a solution on a substrate. The solution comprises a thermoelectric polymer. Solvent of the solution is removed to form a layer of the thermoelectric polymer. The layer is placed in a polar solvent to form a gel comprising the thermoelectric polymer. The gel is cooled to freeze the polar solvent. The gel is placed in a vacuum environment to sublimate the polar solvent from the gel to form an aerogel comprising the thermoelectric polymer.

Provided herein is a superabsorbent polyHIPE composition-of-matter comprising a majority of ionizable pendant groups, capable of absorbing up to 300-fold by mass water while exhibiting a notable mechanical strength in both the dry and wet form, as well as various uses thereof.

The present invention provides for concentrated aqueous silk fibroin solutions and an all-aqueous mode for preparation of concentrated aqueous fibroin solutions that avoids the use of organic solvents, direct additives, or harsh chemicals. The invention further provides for the use of these solutions in production of materials, e.g., fibers, films, foams, meshes, scaffolds and hydrogels.

The present invention relates to a porous silicone body having communicating pores and a three-dimensional network silicone skeleton that forms the pores, wherein the silicone skeleton is formed by polymerization of a bifunctional alkoxysilane and a trifunctional alkoxysilane, and the proportion of unreacted parts in the silicone skeleton is 10 mol % or less. The porous silicone body of the present invention has high flexibility and high heat resistance, and further has excellent recoverability of heat-resistant cushioning properties.

A BAK removal device is constructed as a plug of microparticles of a hydrophilic polymeric gel that displays a hydraulic permeability greater than 0.01 Da. The polymer hydrophilic polymeric gel comprises poly(2-hydroxyethyl methacrylate) (pHEMA). The particles are 2 to 100 μm and the plug has a surface area of 30 mm.sup.2 to 2 mm.sup.2 and a length of 2 mm to 25 mm and wherein the microparticles of a hydrophilic polymeric gel has a pore radius of 3 to 60 μm.

The invention provides compositions featuring chitosan and polyethylene glycol and methods for using such compositions for the local delivery of biologically active agents to an open fracture, complex wound or other site of infection. Advantageously, the chitosan-PEG compositions can be loaded with one or more antimicrobial agents, including hydrophobic agents, and can be tailored to the needs of particular patients at the point of care (e.g., in a surgical suite, clinic, physician's office, or other clinical setting).

A compound made by copolymerizing a poly(N-isopropylacrylamide) chain transfer agent, an acrylate salt, and a polyethylene glycol diacrylate. A compound made by copolymerizing a polyethylene glycol, a glycerol ethoxylate, and an aliphatic diisocyanate.

The present invention relate to three dimensional porous polysaccharide matrices able to induce mineralisation of a tissue in osseous site, as well as in non-osseous site, in the absence of stent cells or growth factors.

Mechanically strong, biodegradable and reusable aerogels are disclosed, which can be made with a cross-linked cellulose ester, and which exhibit a low density and high porosity. The aerogels disclosed herein may be used as sorbent materials and can be modified with a hydrophobic and/or oleophilic agent.

A method of manufacturing a thermally insulating product comprises: (a) forming a mixture comprising solvent and gel network former and optionally foaming agent; (b) dispersing a thermally insulating filler in the mixture; and (c) drying the mixture to form the thermally insulating product.
