Hydrogen research fuels new solar ideas for green energy (10/12/2019)
New
research led by Curtin University explores the use of methanol as a storage for
hydrogen fuel, providing a potential green option for the extraction and
creation of this zero pollution energy source.
Green hydrogen: Research to enhance efficiency (10/12/2019)
Laboratory
experiments and a parabolic flight campaign have enabled an international team
of researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) to gain new
insights into water electrolysis, in which hydrogen is obtained from water by
applying electric energy. Water electrolysis could play a key role in the
energy transition if efficiency improvements can be achieved. The findings
published recently in the journal Physical Review Letters offer a possible
starting point for enhancing the environmental impact of hydrogen-based
technologies.
New function for plant enzyme could lead to green chemistry (10/12/2019)
Scientists
at the U.S. Department of Energy's Brookhaven National Laboratory have
discovered a new function in a plant enzyme that could have implications for
the design of new chemical catalysts. The enzyme catalyzes, or initiates, one
of the cornerstone chemical reactions needed to synthesize a wide array of
organic molecules, including those found in lubricants, cosmetics, and those
used as raw materials for making plastics.
Simple experiment explains magnetic resonance (10/12/2019)
Physicists
at University of California, Riverside, have designed an experiment to explain
the concept of magnetic resonance. The project was carried out by undergraduate
students in collaboration with local high school teachers.
Research shows ramping up carbon capture could be key to mitigating climate change (10/12/2019)
As
the world gathers in Madrid to discuss how to reduce greenhouse gas emissions
to fight climate change, a newly released study makes the case that trapping
emissions underground could go a long way toward solving the problem.
A new memristor-based neural network inspired by the notion of associative memory (10/12/2019)
Classical
conditioning is a psychological process through which animals or humans pair
desired or unpleasant stimuli (e.g., food or a painful experiences) with a
seemingly neutral stimulus (e.g., the sound of a bell, the flash of a light,
etc.) after these two stimuli are repeatedly presented together. Russian
psychologist Ivan Pavlov studied classical conditioning in great depth and
introduced the idea of "associative memory," which entails building
strong associations between the pleasant/unpleasant and neutral stimuli.
Researchers develop generator that uses substance to convert waste heat into clean electricity (10/12/2019)
UT
Dallas researchers have developed a generator prototype that uses liquid metal
to convert waste heat into clean electricity. From left: Electrical engineering
doctoral students Tianyu Chen and Mahshid Khoshlessan, and Dr. Babak Fahimi,
Distinguished Chair in Engineering and professor of electrical engineering,
monitor the performance of a smart variable speed motor, which can follow
commands wirelessly.
Intel Introduces cryogenic control chip 'Horse Ridge' to enable control of multiple quantum bits (10/12/2019)
Intel
has announced the development of a cryogenic control chip it calls "Horse
Ridge." The chip is can control multiple qubits in a quantum computer. In
its announcement, Intel claims that development of the chip represents a major
milestone on the path toward a truly viable quantum computer. Also, as part of
its announcement, Intel claims that other players in the quantum computer
development world have neglected an important part of any such computer—a way
to control many qubits at the same time.
Artificial cells act more like the real thing (08/12/2019)
Protocells—artificial
cells—that are active and mimic living cells by moving independently and that
are biocompatible and enzymatically active are now possible using an improved method
developed by Penn State researchers.
Electron correlations in carbon nanostructures (07/12/2019)
New materials are needed to further reduce the size of electronic components and thus make devices such as laptops and smartphones faster and more efficient. Tiny nanostructures of the novel material graphene are promising in this respect. Graphene consists of a single layer of carbon atoms and, among other things, has a very high electrical conductivity. However, the extreme spatial confinement in such nanostructures influences strongly their electronic properties.
