Fuel cell materials studied for many kinds of environments
Hydrogen is the key ingredient in fuels for fuel cells, but today's fuels -- diesel or regular gasoline, natural gas, or methanol -- can be used as the source of hydrogen protons to pass through a membrane to the oxygen side of the fuel cell, where electrochemical energy, water and heat are produced.

Rx for contact lenses: Mobility + lubricity = comfort and safety
Contact lens comfort and safety should be enhanced by greater lens mobility and lubricity, according to research by Clayton Radke, Ph.D., at the University of California, Berkley. The findings are presented in the July issue of Industrial & Engineering Chemistry Research, a peer-reviewed journal of the American Chemical Society. (2001-05-03)

Artificial muscles release medicine from tiny implants
Scientists have come one step closer to creating 'smart' medical implants with the development of tiny artificial muscles at Ohio State. Researchers here have designed implantable capsules perforated with microscopic holes to dispense medication, with each hole guarded by a tiny ring of artificial muscle made of soft, gel-like plastic.

Bone produced from skin and gum tissue
Using engineered skin and gingiva (gum tissue) cells, researchers at the University of Michigan School of Dentistry have produced complete bones with the same hard outer coating, spongy interior and marrow core as naturally produced bone. (2000-05-18)

Improved biodegradable hydrogels
Two novel biodegradable hydrogels developed by a Cornell University fiber scientists have potential applications for controlling and delivering many kinds of medications inside and outside the body, for anchoring biological substances such as skin and vascular tissues and may even be used to introduce viruses to the body for gene therapy.

Ph.D. Degree Research Results In Patent For Low-Cost Pharmaceutical Filters Made From Seafood Waste
Virginia Tech student Jason Todd's dissertation research has resulted in a new, low-cost process for purifying proteins using a seafood byproduct. Chitosan beads with a patented ligand attachment are used to capture antibodies from blood serum or cell cultures. Such antibodies are used in diagnosis and treatment of diseases, as well as testing for drug abuse. (1999-05-24)

New Contact Lens Material Could Lessen Risk Of Eye Infection
New materials that may extend the wear of contact lenses and lessen the risk of eye infection will be described by researchers from the University of California, Berkeley. (1999-03-23)

Tiny Coated Beads Could 'Explosively' Release Drugs On Cue Within Tumors
Researchers at Duke University and Access Pharmaceutical Inc. of Dallas, Texas, are jointly devising microscopic beads that can dump drugs directly onto tumors by mimicking the way substances are secreted within cells (1997-04-16)
