Electrochemical reactions, which will play an important role in the future of energy supply, can now be explained in detail
Electrochemistry is playing an increasingly important role: Whether it is fuel cells, electrolysis or chemical energy storage, chemical reactions controlled by electric current are used. The decisive factor in all these applications is that the reactions are as fast and efficient as possible. An ...
Molecular approach enables light-driven photochemistry in the dark for the first time
Using the energy from the sun as efficiently as nature does and converting it into chemical energy could drastically reduce global CO2 emissions. A research team from the Leibniz Institute of Photonic Technology (Leibniz IPHT) and the Friedrich Schiller University Jena has now come one step ...
Green, sustainable and biodegradable polymers
Lemonade, juice and mineral water often come in PET bottles. While these are practical and functional, their production is complex and not necessarily sustainable. The starting material for terephthalic acid, which is used to produce saturated polyesters such as PET (Polyethylene terephthalate), ...
The nanofluid is made from commercially available sodium using household blender
Researchers from the University of Houston have demonstrated that an inexpensive and non-toxic nanofluid can be used to efficiently recover even heavy oil with high viscosity from reservoirs. The nanofluid, made in a common household blender using commercially available sodium, allowed for ...
Recent years have witnessed explosive development in electrochemical CO2 reduction into valuable chemicals or fuels. The CO2 electroreduction is considered as a promising route to utilize renewable electricity from intermittent energy, such as solar, winder, geothermal power, etc. Designing ...
Voltage can be used for chemical reactions: New model for pyroelectric reactions developed
Pyroelectricity is a phenomenon in physics in which heat can be converted into electricity via certain crystals or into a voltage that can be used for chemical reactions. While the first application is already used in devices such as motion detectors today, the second application, although ...
New technique to reassemble, revivify, and reuse a catalyst
The future economy based on renewable and sustainable energy sources might utilize battery-powered cars, large-scale solar and wind farms, and energy reserves stored in batteries and chemical fuels. Although there are examples of sustainable energy sources in use already, scientific and ...
Barrier to building ultra-fast battery energy storage systems knocked down
For years, researchers have aimed to learn more about a group of metal oxides that show promise as key materials for the next generation of lithium-ion batteries because of their mysterious ability to store significantly more energy than should be possible. An international research team, co-led ...
Electrochemical CO2 reduction reaction (CO2RR) is a promising approach to convert CO2 into useful chemicals. A research team led by Prof. ZHANG Suojiang from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences prepared a manganese (Mn) single-atom catalyst (SAC) with ...
Machine learning models can rapidly and accurately estimate key chemical parameters related to molecular reactivity
Creating computers that can teach themselves how chemical structure dictates the fundamental properties of molecules and then using that knowledge to predict the properties of novel molecules could help to design cleaner energy and industrial systems. KAUST researchers have developed a machine ...
