The flubber of the future? It's under development at the University of North Texas (UNT). The so-called "smart gel" has become the catch phrase for water-based, gelatin-like polymers created in labs. The gels have physical properties that change in response to temperature, light, pH and acidic balances, and electric fields. Dr. Zhibing Hu, an associate professor of physics at UNT, heads the research. His work incorporates different materials on a hydrogel surface so that it can change into a specific pattern when induced by a certain stimulus. Gels made to date show lattice or other surface patterns that remain visible or invisible by simply switching between room and body temperature. Possible future uses for this type of gel include acting as an optical gauge that monitors environmental conditions, such as metal ions in water, or as a miniature sensor that can detect enzyme activity. Toys or signs with designs and wording that appear and disappear in response to changing temperatures also would be a possibility. E-mail firstname.lastname@example.org.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
