Using a genetic algorithm to uncover new catalyst molecules for organic synthesis
A team of researchers have used a computational method inspired by evolution to discover an organic catalyst with better performance than known catalysts. As the team reports in the journal Angewandte Chemie, a genetic algorithm suggested new, catalytically active molecular structures for a ...
A complete wet chemistry laboratory in suitcase format: Artificial intelligence finds new materials in record time
A team of chemical engineering researchers has developed a self-driven lab that is capable of identifying and optimizing new complex multistep reaction routes for the synthesis of advanced functional materials and molecules. In a proof-of-concept demonstration, the system found a more efficient ...
A special catalyst enables a “dream reaction”
Menthol and cannabinoids are important for the chemical industry. A team led by Prof. Benjamin List has now found a new way to synthesize both substances - cheaper and more efficient than before. Our toothpaste contains it, you can find it in cold remedies, and it makes our chewing gum tasty: ...
Reactions without solvents
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 ...
First synthesis of a compound with aromatic nitrogen rings
For the first time, a compound containing aromatic rings of nitrogen atoms has been synthesized. The compound of nitrogen and potassium was produced under extremely high pressures and temperatures. It has a very complex structure, but its major building block is the planar ring of six nitrogen ...
This might be helpful to tackle synthesis problems
Vladimir Vasilyevich Markovnikov was a 19th century Russian chemist who worked at the universities of St. Petersburg, Odessa and Moscow, among others. The so-called Markovnikov rule, well known already with young students of chemistry, is named after him. This rule says that when protic acids are ...
Potential applications in food, cosmetics and pharmaceutical industries
A team of scientists led by Professor Tanja Gulder at Leipzig University’s Institute of Organic Chemistry, together with colleagues from the University of Regensburg, has developed a simplified and efficient method for the artificial production of terpenes. Terpenes are a very extensive and ...
Flexible polymers made with a new generation of the Nobel-winning “click chemistry” reaction find use in capacitors and other applications
Society’s growing demand for high-voltage electrical technologies – including pulsed power systems, cars and electrified aircraft, and renewable energy applications – requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical ...
Young Bayreuth scientists give names to new classes of substances
N-Heterocyclic compounds are central active ingredients of many drugs and at the same time important building blocks of new organic materials for the energy transition. Researchers at the University of Bayreuth, led by Prof. Dr. Rhett Kempe, now present in "Nature Communications" a concept for ...
AI and human touch combine to revolutionize chemical synthesis
With a big assist from artificial intelligence and a heavy dose of human touch, Tim Cernak's lab at the University of Michigan made a discovery that dramatically speeds up the time-consuming chemical process of building molecules that will be tomorrow's medicines, agrichemicals or materials. The ...
