Forward osmosis membrane for seawater desalination and method for preparing the same
A forward osmosis membrane for seawater desalination and a method for preparing the same. The forward osmosis membrane has a composite membrane structure including a nonwoven fabric layer; a hydrophilic polymer layer; and a polyamide layer. The hydrophilic polymer layer formed on the nonwoven fabric layer facilitates an inflow of water from the feed water to the draw solution to enhance flux and realize high water permeability in the direction of osmosis. The polyamide layer not only secures contamination resistance and chemical resistance but also minimizes the back diffusion of salts of the draw solution in the direction of reverse osmosis. Hence, the forward osmosis membrane of the present invention is greatly useful for desalination of high-concentration seawater.
External penile prosthesis for augmenting male potency
An elastomeric device for improving the erection of the human penis may include a frustoconical collar sized to receive and snugly jacket the user's penis and apply effective pressure on the dorsal penile veins, and a radially extending pubic shield adapted to overlay the pubic area of the user. An elastic strap attached to the pubic shield may encircle the underside of the scrotum to apply effective pressure on the deep veins behind the scrotum and to retain the device on the user's penis during sexual activity. When used in combination with a conventional vacuum erection device, substantially airtight seals are established around the open end of the vacuum device, the base of the penis, and the anterior sealing surface of the pubic shield during evacuation pumping. Related methods are also described.

CORE-SHELL MICRONEEDLE PLATFORM FOR TRANSDERMAL AND PULSATILE DRUG/VACCINE DELIVERY AND METHOD OF MANUFACTURING THE SAME
A core-shell microneedle system and a method of manufacturing the microneedle system provides a pulsatile drug delivery system which is programmed to release drugs/vaccines at predictable times using biodegradable polymers and with controllable dosages. This microneedle system can be fully embedded into the skin and then release drugs/vaccines as sharp bursts in a timely manner, similar to multiple bolus injections.
NANOPOROUS COMPOSITE SEPARATORS WITH INCREASED THERMAL CONDUCTIVITY
Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise Al.sub.2O.sub.3, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO.sub.2, SiO.sub.2, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent. Once dried, the coating may be removed from the substrate, thus forming the nanoporous composite separator. A nanoporous composite separator may provide increased thermal conductivity and dimensional stability at temperatures above 200° C. compared to polyolefin separators.
