Researchers at the ARC Centre of Excellence in Exciton Science have made an important discovery with significant implications for the future of solar cell material design.
Plastics are often derived from petroleum, contributing to reliance on fossil fuels and driving harmful greenhouse gas emissions. To change that, Great Lakes Bioenergy Research Center (GLBRC) scientists are trying to take the pliable nature of plastic in another direction, developing new and renewable ways of creating plastics from biomass.
A team led by David Mooney at Harvard's Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engineering and Applied Sciences (SEAS) is now reporting in Nature Biotechnology a material-based T-cell-expansion method using APC-mimetic biomaterial scaffolds, which helps achieve greater expansion of primary mouse and human T cells than existing methods.
Scientists at the University of Washington announced that they have built and tested a new biomaterial-based delivery system -- known as a hydrogel -- that will encase a desired cargo and dissolve to release its freight only when specific physiological conditions are met.
TUAT researchers have achieved the new synthetic route of conjugated tetraenes from inexpensive and easily available 1,3-butadiene and substituted acetylenes by a one-pot approach under mild conditions. This is the most straightforward synthetic method ever reported. This new method has been published in the ACS journal, Organometallics.
Material chemists in the Kingdom of Saudi Arabia have developed a superporous solid made up of a patchwork of metal ions and organic linkers (a metal-organic framework, or MOF) that can suck up to 200 percent of its own weight in atmospheric moisture. The technology, presented Jan. 11 in the journal Chem, could be applied to regulating humidity levels, particularly in confined environments such as aircraft cabins and air-conditioned buildings.
Scientists are one step closer to artificial muscles. Orthotics have come a long way, yet innovation lapsed when it came to compensating for muscle power -- until now. A collaborative research team has designed a wearable robot to support a person's hip joint while walking. The team, led by Minoru Hashimoto, a professor at Shinshu University in Japan, published the details of their prototype in Smart Materials and Structures.
A research team at Kyushu University's International Institute for Carbon-Neutral Energy Research (I2CNER) developed a flow-type polymer electrolyte cell for power storage. The cell reduces oxalic acid (OX) to glycolic acid, which has a higher volumetric energy-storage capacity than hydrogen gas. Newly fabricated TiO2 cathode enhanced the speed and efficiency of OX reduction. This competitive energy-storage device could be used to balance out the fluctuations in renewable power supplies.
UCSB mechanical engineer Daniel Gianola and colleagues predict how seemingly disparate disordered materials fail, using 'softness' as a criterion.
Materials chemists have been trying for years to make a battery that can store solar energy in chemical bonds rather than electrons, releasing the energy later as heat. Now a group of materials chemists at the University of Massachusetts Amherst led by Dhandapani Venkataraman, with Ph.D. student and first author Seung Pyo Jeong and others report that they have solved a major hurdle by developing a polymer-based system.
