Reactions without solvents

16-Mar-2023

A combination of photochemistry and mechanochemistry saves 98 per cent solvent and 80 per cent energy in a number of reactions. What’s more, the process takes less time than it does in solution. Light-driven chemical reactions so far were usually conducted with large amounts of solvents that are ...

How to trigger chemical reaction without the use of solvent

01-Feb-2023

Bottle, glass tube and solvent, those are what we usually find in a chemistry lab or industry. Chemistry using solvents, or liquid based materials is the traditional way of synthesis. Although it is very efficient, an inevitable question is how to recycle solvent safely and environment friendly? ...

Advanced milling technique produces slow-release soil nutrient crystals

13-May-2022

A purely mechanical method can produce a novel, more sustainable fertiliser in a less polluting way. That is the result of a method optimised at DESY's light source PETRA III. An international team used PETRA III to optimise the production method that is an adaptation of an ancient technique: by ...

Nanometer-sized corundum particles can now be produced amazingly easily

01-Nov-2019

Automotive catalysts, among others, and materials for dental implants could become more robust and easier to manufacture than ever before. This is because chemists at the Max-Planck-Institut für Kohlenforschung in Mülheim an der Ruhr have found a way to produce corundum (also known as ...
