10/09/2019There's nothing new in treating water by sorption of organic solvents such as trichloroethylene (TCE). But finding a method that neutralizes these contaminants, instead of just shifting them somewhere else, is no mean feat. A team led by Anna Śrębowata, has improved a flow method of catalytic hydrotreatment, that is, transforming TCE into environmentally friendly hydrocarbons. ...
10/09/2019An international team of researchers has reported a new way to safeguard drones, surveillance cameras and other equipment against laser attacks, which can disable or destroy the equipment. The capability is known as optical limiting.
09/09/2019A team including Oak Ridge National Laboratory and University of Tennessee researchers demonstrated a novel 3D printing approach called Z-pinning that can increase the material's strength and toughness by more than three and a half times compared to conventional additive manufacturing processes.
09/09/2019In power electronics, semiconductors are based on the element silicon - but the energy efficiency of silicon carbide would be much higher. Physicists of the University of Basel, the Paul Scherrer Institute and ABB explain what exactly is preventing the use of this combination of silicon and carbon in the scientific journal Applied Physics Letters.
06/09/2019Many industrial buildings rely on ultrasound instruments that continually monitor the structural integrity of their systems without damaging or altering their features. One new technique draws on laser technology and candle soot to generate effective ultrasonic waves for nondestructive testing and evaluation.
06/09/2019Scientists at Tokyo Institute of Technology (Tokyo Tech) find a simple method for producing atomically thin layers of oxidized borophene, a promising 2D boron-based nanomaterial that could serve in a variety of fields.
05/09/2019The new study explores the subtle interplay of the primary components of such devices and outlines a theoretical framework for understanding the underlying fuel-forming reactions. The results suggest strategies for improving the efficiency and performance of such hybrid technologies, bringing them a step closer to commercial viability.
05/09/2019For the first time, researchers have managed to view previously inaccessible details of certain chemical processes. They have shown there are significant discrete stages to these processes which build on our knowledge of chemical synthesis. These details could aid in the development of methods to synthesize chemicals with greater control and precision than ever before. ...
04/09/2019Scientists from the CNRS and Aix-Marseille Université have recently shown how valuable light-sensitive macromolecules are: when exposed to the right wavelength of light, they can be transformed so as to change, erase or decode the molecular message that they contain. The results of this research were published on Sept. 4, 2019, in Nature Communications.
04/09/2019An electrocatalysis reactor built at Rice University recycles carbon dioxide to produce pure liquid fuel solutions using electricity. The scientists behind the invention hope it will become an efficient and profitable way to reuse the greenhouse gas and keep it out of the atmosphere.
