Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources — such as solar and wind — promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene, ethanol and acetic acid are particularly useful as feedstocks for the chemical industry and powering vehicles.

Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also allows for the efficient and high-quality growth of crystals at a lower cost. Scientists can make semiconductors more efficiently with a reduced need for raw materials and power. Researchers from Nagoya University in Japan led the study, which was published in Scientific Reports.

Controlling the crystal phase of cobalt nanoparticles leads to exceptional catalytic performance in hydrogenation processes, report scientists from Tokyo Tech. Produced via an innovative hydrosilane-assisted synthesis method, these phase-controlled reusable nanoparticles enable the selective hydrogenation of various compounds under mild conditions without the use of harmful gases like ammonia. These efforts could lead to more sustainable and efficient catalytic processes across many industrial fields.

Physical chemist Alexandrova is known for her research in theoretical and computational chemistry, particularly focusing on the electronic structure and dynamics of complex systems. Her work often involves the development and application of computational methods to understand and predict the behavior of materials and molecules.

The propagation of information can speed up over time in systems of certain quantum particles, a theoretical analysis by RIKEN physicists has revealed.

Researchers at the Institute of Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: they were able to entangle three particles of light in a high-dimensional quantum property related to the "twist" of their wavefront structure.
