Ultrafast dissociation of molecules studied at BESSY II

Findings could deepen our understanding of chemical reactions at the molecular level

04-Dec-2024 - For the first time, an international team has tracked at BESSY II how heavy molecules – in this case bromochloromethane – disintegrate into smaller fragments when they absorb X-ray light. Using a newly developed analytical method, they were able to visualise the ultrafast dynamics of this ...

Hydrogen chloride can now be stored, processed, and electrolyzed safely thanks to breakthrough

New method paves the way for safer, more sustainable hydrogen and base chemical production

05-Apr-2024 - A research team at Freie Universität Berlin led by Professor Sebastian Hasenstab-Riedel has successfully developed a method for storing and electrolyzing gaseous hydrogen chloride in the form of an ionic liquid. The method allows the hydrogen chloride created as a by-product in traditional ...

New material will make locally flexible diodes possible

Temperature changes material characteristics: Researchers find new material with significant potential for electronics applications

08-Nov-2022 - Diodes allow directed flows of current. Without them, modern electronics would be inconceivable. Until now, they had to be made out of two materials with different characteristics. A research team at the Technical University of Munich (TUM) has now discovered a material that makes it possible to ...

Halogens emitted from oceans amplify global warming of methane in the atmosphere

Iodine, bromine and chlorine transferred from the ocean have increased the lifetime and greenhouse effect of this gas by 6% to 9% over the century.

23-May-2022 - An international team, led by researchers from the Spanish National Research Council (CSIC), has performed climate-related chemistry simulations to assess the impact of oceanic emissions of halogenated compounds (iodine, bromine and chlorine) on methane in the atmosphere, the second most ...

Stanford researchers make rechargeable batteries that store six times more charge

Serendipitous discovery: "It took us about at least a year to really realize what was going on"

01-Sep-2021 - An international team of researchers led by Stanford University have developed rechargeable batteries that can store up to six times more charge than ones that are currently commercially available. The advance, detailed in a new paper published Aug. 25 in the journalNature, could accelerate the ...

Novel Technique to Produce Cheaper and More Efficient Chlorine

12-Mar-2020 - Chlorine (Cl₂) is one of the most widely used industrial chemicals in the world today, with75 million tons produced annually.A team of researchers, affiliated with UNIST has recentlyfound a way to make the manufacture of chlorine more efficient andaffordable. This is expected to be of great ...

How ice particles promote the formation of radicals

Chemistry in clouds

10-Dec-2018 - Certain molecules with fluorine, chlorine or bromine, together with water, can release harmful substances into the atmosphere. The production of chlorofluorocarbons, which damage the ozone layer, has been banned as far as possible. However, other substances can also tear holes in the ozone layer ...

Improved understanding of industrial electrode processes

The findings could help save carbon dioxide in the future

24-Aug-2018 - In the industrial production of chlorine, recently special electrodes have been introduced, which consume much less current than conventional systems. The method requires oxygen which is introduced into hot, highly concentrated sodium hydroxide solution, in which it is poorly soluble. It is still ...
