Copper-silver-gold nanostructure gives carbon-capture-and-utilization a boost
“We thought if two metals were producing good results, then perhaps three metals would be even better”
18-Mar-2022
Chemists have developed a nano-scale structure that combines copper, gold and silver to work as a superior catalyst in a chemical reaction whose improved performance will be essential if carbon capture and utilization efforts are to succeed in helping to mitigate global warming. In the face of ...
Impossible material made possible inside a graphene sandwich
Towards new 2D materials
21-Jan-2022
Atoms bind together by sharing electrons. The way this happens depends on the atom types but also on conditions such as temperature and pressure. In two-dimensional (2D) materials, such as graphene, atoms join along a plane to form structures just one atom thick, which leads to fascinating ...
The next big thing: A new technology for directly converting carbon dioxide into pure formic acid
Novel electrochemical device based on solid-state electrolyte
05-Jan-2022
Anthropogenic emissions of carbon dioxide bring a series of climatic and environmental problems including global warming. Artificially upcycling of carbon dioxide into value-added fuels and chemicals, powered by "green electricity" of renewable energy, provides an elegant route to close the ...
Machine learning deployed to fast-track industrial optimization process
Minimization of defects in ALD passivation films with only two steps through Bayesian optimization
16-Dec-2021
An interdisciplinary team of researchers at the Max Planck Institute for Intelligent Systems, the Max Planck Institute for Solid State Research, the Technical University of Munich, and Robert Bosch GmbH deploy Bayesian Machine Learning methods to fast-track the optimization process of coating ...
3D printing approaches atomic dimensions
A new electrochemical technique makes the production of complex metallic objects at the nanoscale possible
22-Nov-2021
In recent years 3D printing, also known as additive manufacturing, has established itself as a promising new manufacturing process for a wide variety of components. Dr Dmitry Momotenko, a chemist at the University of Oldenburg, has now succeeded in fabricating ultrasmall metal objects using a new ...
A new generation of particle accelerators aims at taking cancer therapy, drug detection and material analysis to a higher level
Additively manufactured copper components for linear accelerators
04-Nov-2021
World first: Fraunhofer IWS for the very first time prints quadrupole components for linear accelerator.These linear accelerators are so compact that they are becoming affordable even for smaller hospitals, airports and laboratories. To support this development, the Fraunhofer Institute for ...
The importance of good neighbors in catalysis
Are you affected by your neighbours? So are nanoparticles in catalysts
04-Nov-2020
New research from Chalmers University of Technology, Sweden, published in the journals Science Advances and Nature Communications, reveals how the nearest neighbours determine how well nanoparticles work in a catalyst. "The long-term goal of the research is to be able to identify ...
Effective pathway to convert CO2 into ethylene discovered
Promising way to to transform ethylene production into a greener industry
24-Sep-2020
A research team from Caltech and the UCLA Samueli School of Engineering has demonstrated a promising way to efficiently convert carbon dioxide into ethylene -- an important chemical used to produce plastics, solvents, cosmetics and other important products globally. The scientists developed ...
Copper ion unlocks magnesium's potential in next-generation battery
New magnesium battery demonstrates dramatic improvement of performance
14-May-2020
Researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have come a step closer to making a viable, high-output battery based on magnesium (Mg), an element the United States Geological Survey reports is far more abundant than ...
Lighting material of the future
Green luminescent substance is a hot candidate for producing OLEDs
07-May-2020
At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale - that means it is practically made for use in large-area room ...
