Cheap water treatment

10/09/2019

There'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. ...

Layering on the strength

09/09/2019

A 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.

Silicon as a semiconductor: Silicon carbide would be much more efficient

09/09/2019

In 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.

Laser-based ultrasound approach provides new direction for nondestructive testing

06/09/2019

Many 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.

Chemistry in motion

05/09/2019

For 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. ...

Secret messages hidden in light-sensitive polymers

04/09/2019

Scientists 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.

Rice reactor turns greenhouse gas into pure liquid fuel

04/09/2019

An 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.
