    Abstract: The present invention provides a self-healing biocompatible elastomer comprising polymeric chains comprising units of formula (A1), wherein R1 is selected from the group consisting of a linear (C2-C20) alkylene and —R4-S—S—R4′-, wherein R4 and R4′ are independently a linear (C1-C10) alkylene; R2 is a linear or cyclic (C4-C10) alkylene; and R3 is selected from the group consisting of a polybutadiene, a polybutene, a polyethylene, a polypropylene, and a polyisoprene, wherein the elastomer is crosslinked by hydrogen bonds between urethane linkages. Further provided is a one-pot method for preparing a self-healing biocompatible elastomer. The invention further provides an antibacterial composition and a wound dressing comprising the self-healing biocompatible elastomer. Formula (A1)

    Abstract: A high-efficiency, motorless purge system for closed-cycle absorption heat pumps, adapted for both absorption heat transformers and absorption chillers, using a series of valves to control the entry and exit of absorbent solution into a low-pressure, secondary absorption vessel. A small percentage of the total circulating solution is forced under pressure into the secondary absorption vessel via a spray nozzle, causing adiabatic absorption of absorbate vapor by the solution. Non-condensable gases accumulate in the secondary absorber until a certain vapor pressure is reached, upon which, gas, and possibly liquid, are transferred to an exhaust vessel having an exit vent for non-condensable gases. In an absorption chiller system, the secondary absorber has an internal heat exchanger to lower the temperature of the solution within, to facilitate the absorption process.

    Abstract: A dielectric gradient metasurface optical device provides optical wavefront shaping using an ultrathin (less than 100 nm thick) layer of nanoscale geometric Pancharatnam-Berry phase optical elements deposited on a substrate layer. The optical elements are nanobeams composed of high refractive index dielectric material. The nanobeams have uniform size and shape and are arranged with less than 200 nm separations and spatially varying orientations in the plane of the device such that the optical device has a spatially varying optical phase response capable of optical wavefront shaping. The high refractive index dielectric material may be materials compatible with semiconductor electronic fabrication, including silicon, polysilicon, germanium, gallium arsenide, titanium dioxide, or iron oxide.
