UJ researchers take a novel step to change hydrogenation into a safe, low energy process. They use a very stable three phase emulsion to transform a toxic waste product into valuable feedstock. The process does not require flammable, compressed hydrogen gas. The emulsion catalysis efficiently hydrogenates nitrobenzene at room temperature to output aniline. Aniline is widely used in the pharmaceutical industry. The bi-metallic hydrogenation catalyst is fully recovered afterwards.
Applying compost in apple orchards could reduce the need for synthetic fertilizer.
More than half of the structures in the contiguous United States are exposed to potentially devastating natural hazards such as floods, tornadoes and wildfires. Increasing temperatures and environmental changes contribute to this trend, according to a new study in the AGU journal Earth's Future.
As you drive down the highway, you may notice an increasing number of hybrid and electric vehicles. Alternative energy automobiles are on the rise contributing to the global effort to reduce carbon emissions. As we move together down this road, researchers are looking to determine new solutions to this ongoing problem.
Columbia Engineering researchers who are leading experts in computer security recently presented two major papers on memory safety that make computer systems more secure at the International Symposium on Computer Architecture. This new research, which has zero to little effect on system performance, is already being used to create a processor for the Air Force Research Lab.
The study predicts flow and temperature in river networks.
UCL experts have created a mathematical model of urban car use, and have concluded that current levels of city car use are unsustainable as populations grow.
Researchers from Northwestern Engineering and the University of Messina in Italy have developed a new magnetic memory device based on antiferromagnetic materials that could bolster memory-intensive computing applications, including artificial intelligence and cryptocurrency mining.
Engineers at Duke University have devised a system for manipulating particles approaching the miniscule 2.5 nanometer diameter of DNA using sound-induced electric fields. Dubbed "acoustoelectronic nanotweezers," the approach provides a label-free, dynamically controllable method of moving and trapping nanoparticles over a large area. The technology holds promise for applications in the fields ranging from condensed matter physics to biomedicine.
The mystery of an exotic kind of supraconductivity has been solved -- by showing that it just does not exist. An effect, which has been celebrated since the 1990s has now been shown to be standard superconductivity. Still, this realization leads to important new ideas.
