摘要： In particles removal with extremely high filtration efficiency and the ability to block submicron airborne particles by a sieving mechanism is provided. This novel nanoporous filter advantageously combines extremely high transmittance for visible light and ultraviolet light, reusability after cleaning or disinfection by ultraviolet irradiation or simple washing, a customizable sieving pore size ranging from a few nanometers to 500 nanometers, and the ability to carry bactericidal, virucidal or other reagents or particles on the nano or micro scale.

摘要： A polymer composition for producing gel extruded articles is described. The polymer composition contains at least three different polyethylene polymers, namely a lower molecular weight polyethylene polymer, a mid-range molecular weight polyethylene polymer, and a high molecular weight polyethylene polymer. Combining the different polyethylene polymers in different ratios can optimize not only mechanical properties but improve processing.

摘要： A membrane-based desorption cooling method for passive thermal management is presented. The module includes: (i) a covering layer for thermally conducting and transferring heat from a device to a solution; (ii) a solution layer for confining H2O/absorbent mixtures in a multi-compartment frame; (iii) a membrane layer configured to act as an interface between the solution and air; and (iv) a supporting layer configured to increase the mechanical strength and including apertures to permit mass transfer from the membrane through the supporting layer. The present membrane-based desorption cooling module is able to be used for thermal management of solar photovoltaic (PV) panels, electronics, batteries, or any other devices that require heat removal.

摘要： A cleaning system includes a planar material beneath a soiled grow table. The planar material is non-porous except for a drain. Above the planar material is a plate layer including at least two layers of runners arranged in a grid where each successive layer is offset at an angle with respect to the grid of a previous layer. The plate layer rests upon the non-porous material. An upper layer covers the plate layer and has a plurality of holes. A roller table is provided for slideably supporting the grow table. Nozzles are positioned over the grow table and is/are interfaced to a pump for receiving and spraying liquid from the pump downwardly towards the grow table. The liquid and impurities (e.g., soil, leaves) fall to the upper layer and through the plurality of holes for cleaning and filtering the liquid before the liquid is returned to the pump.
