The world fell in love with plastics because they're cheap, convenient, lightweight and long- lasting. For these same reasons, plastics are now trashing the Earth. Colorado State University chemists have announced in the journal Science another major step toward waste-free, sustainable materials that could one day compete with conventional plastics.
Researchers at Carnegie Mellon University have used an inexpensive 3-D printer to produce flat plastic items that, when heated, fold themselves into predetermined shapes, such as a rose, a boat or even a bunny. Lining Yao, assistant professor in the Human-Computer Interaction Institute, said these self-folding plastic objects represent a first step toward products such as flat-pack furniture that assume their final shapes with the help of a heat gun.
Jin-Kyu Rhee, associate professor at Ewha Womans University in South Korea, will discuss his new research and the potential of 3-D printing technology for food production at the American Society for Biochemistry and Molecular Biology annual meeting during the 2018 Experimental Biology meeting to be held April 21-25 in San Diego.
An improved performance (activity, selectivity and stability) catalyst for the LA hydrogenation reaction is developed based on carbon supported ruthenium with low metal particle size (1.2 nm).
Antifreeze glycoproteins (AFGPs), produced by polar fishes, are known as the inhibitor of ice growing while its mechanism has remained a mystery. Using molecular simulations, scientists have identified a unique molecular binding mechanism that helps keep non-mammalian creatures in sub-zero temperatures from freezing. The finding has potential future applications for better preserving food and biological tissue under extreme temperatures.
Engineers at the US Army Research Laboratory and the University of Maryland have developed a technique that causes a composite material to become stiffer and stronger on-demand when exposed to ultraviolet light.
Some Illinois researchers working on artificial muscles are seeing results even the fittest individuals would envy, designing muscles capable of lifting up to 12,600 times their own weight. Assistant professor of mechanical science and engineering Sameh Tawfick, Beckman postdoctoral fellow Caterina Lamuta, and Simon Messelot recently published a study on how to design super strong artificial muscles in the journal Smart Material and Structures. The new muscles are made from carbon fiber-reinforced siloxane rubber and have a coiled geometry.
Scientists developed a versatile modification method of graphene without destroying it, which can build strong covalent bonds with polymers. Conductive materials obtained through such method are promising for the development of flexible organic electronics.
Using caffeine as a catalyst, MIT researchers have devised a way to create gummy, biocompatible gels that could be used for drug delivery and other medical applications.
Researchers at the University of Washington have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities.
