Graphene-related materials (GRMs) are often used to reinforce polymers. In small concentrations of up to five weight percent, GRMs can significantly enhance the strength, electrical conductivity and thermal transport of composites for a variety of applications. However, being a relatively new set of materials, graphene and GRMs need to be carefully assessed in order to identify potential adverse effects prior commercialization.
A federal grant program to impel the global competitiveness of the United States by expediting the manufacture of high-tech materials has granted $1.8 million to Indiana University scientists who discovered the brightest-known fluorescent solid materials in the world.
Bioethanol production has the potential to replace petrochemical-derived fuels for sectors such as the automotive industry. A new paper appearing in Energies has explored the production of this alternative fuel from bacteria and fungi. Researchers from the Department of Chemical Engineering at Ariel University in Israel have contributed to the paper.
A team of researchers led by the University of Minnesota Twin Cities has addressed a long-standing puzzle about strontium titanate, an odd metal oxide that can function as an insulator, a semiconductor, or a metal.
Scientists who study materials can be divided into three categories. "You have people who make things, people who make things do things, and people who try to understand why things do what they do," said Jim De Yoreo, a Battelle fellow at Pacific Northwest National Laboratory (PNNL). He places himself into the third category.
Writing in Materials, scientists have presented a multi-analytical study on Nuragic bronze statues. The study shines light on ancient metallurgical techniques and superficial treatments of bronze statues from this period.
In an article recently published in the journal Dental Materials, researchers discussed the role of a novel selective protease inhibitor in slowing the monomer inspired by mussels, i.e., dentine collagen breakdown.
Engineers have encountered difficulty in studying the basic properties of the materials involved as thermoelectric electronic, and computer technologies have been miniaturized to nanometer scale. And in many cases, targets are too small to be seen with optical instruments.
An international collaborative group, for the first time, has been successful in reproducing a topological change of viscous fingering in a numeric manner.
Superconductors are materials with no electrical resistance whatsoever, commonly requiring extremely low temperatures. They are used in a wide range of domains, from medical applications to a central role in quantum computers. Superconductivity is caused by specially linked pairs of electrons known as Cooper pairs.
