Organic dyes with persistent delayed fluorescence and ultralong phosphorescence
A team of researchers from Lithuania has developed organic dyes showing a particularly long afterglow after being excited by light. Doping a polymer with newly synthesized diboraanthracene dyes resulted in an intense red or blue–green dual afterglow, which was composed of persistent thermally ...
Some reactions in the reverse Krebs cycle can also be run under meteorite catalysis
Naturally occurring chemical reactions may have evolved into the biochemical processes we know today. A team of researchers has now discovered that a reaction sequence from the so-called reverse Krebs cycle—a fundamental biochemical process—can also take place without enzymes. The team writes in ...
Low toxicity, high efficiency: ZnSe/ZnS quantum dots as photocatalysts
Chemistry is increasingly making use of the trick plants can do with photosynthesis: driving chemical reactions that run poorly or do not occur spontaneously at all with light energy. This requires suitable photocatalysts that capture light energy and make it available for the reaction. In the ...
Efficient titanium-based catalyst used to produce PEF, the biobased alternative to PET
One possible replacement for drink containers made from PET is polyethylene furandicarboxylate (PEF), made from renewable resources. However, the production of the raw material for PEF from biomass is still rather inefficient. A new titanium-based photocatalyst could be about to change this, ...
Rare-earth metals are indispensable for many technical products, from smartphones, laptops, batteries, electromotors, and wind turbines, to catalysts. In the journal Angewandte Chemie, a Japanese team has now introduced a molecular “cage” with “caps” that can be used to selectively “confine” ...
Clearer reporting of negative experimental results would improve reaction planning in chemistry
Databases containing huge amounts of experimental data are available to researchers across a wide variety of chemical disciplines. However, a team of researchers have discovered that the available data is unsuccessful in predicting the yields of new syntheses using artificial intelligence (AI) ...
Encapsulated peptide blocks communication and virulence of resistant Staphylococcus
Antibiotic-resistant hospital pathogens are not to be underestimated as a health risk. A research team has now introduced a new approach for treating multiple-drug resistant Staphylococcus in the journal Angewandte Chemie. It is based on a synthetic peptide that reduces the virulence of the ...
Luciferin synthesis and organophosphate detection by a luminescent enzymatic cascade
A luminescence reaction modeled on fireflies can detect contamination with organophosphates with high sensitivity, ease, and low cost. At the center of this technology is a new enzymatic method for the synthesis of analogues of luciferin, the substance that makes fireflies glow. As reported by a ...
Relief for Oceans and Landfills?
More than eight million tons of plastic end up in the oceans every year—a serious danger for the environment and health. Biodegradable bioplastics could provide an alternative. In the journal Angewandte Chemie, a research team has now introduced a new method for the production of protein-based ...
Spider silk Janus fibers could attract nerve cells and stimulate their growth
Spider silk has enormous potential in regenerative medicine thanks to being a natural fiber that is tough, stable, and biodegradable. Researchers have now produced double-sided spider silk fibers, which could provide damaged nerve or muscle cells with a platform for growth. As the researchers ...
q&more – the networking platform for quality excellence in lab and process
The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge.
