Polyurethane foam is found in mattresses, furniture and many other products, and it produces a waste stream that is difficult to recycle. However, a team from the University of Twente has now presented a sustainable method in Green Chemistry for converting this widely used material into reusable building blocks.
Sjoerd Rijpkema doesn’t quite understand the exceedingly detailed questions that PhD candidates get during their promotion ceremony. However, he recently came across a promotion with a markedly different approach.
A team from Utrecht University functionalises the C-H-bonds in polyolefins using just UV light without the need for solvents or catalysts, they report in JACS.
These essential building blocks are found in medicines and commonly used insecticides, but they are also difficult to synthesise: alkylidenecyclopropanes. In Nature, an international team presents a new method that makes producing these ring-shaped carbon structures much more efficient.
Using triazine-thiol exchange, a group from Nijmegen was able to program cysteine modifications in peptides by varying the pH, they report in ChemistryEurope.
The 3D bioprinting of functional tissues is a complex, step-by-step process that depends on the designer. Now, however, biomedical engineers at Utrecht University have developed new technology published in Nature that integrates advanced imaging and artificial intelligence, enabling the 3D bioprinter to observe and analyse.
Leuven researchers have found a way to transform toluene into nitriles using electrochemistry, ammonia and… water! They report on this simple and potentially environmentally friendly procedure in ChemElectroChem.
Oyster mushrooms cleaning ditches and trenches. This is the solution with which MycoFarming aims to establish itself. Their biological filtration method cleans the water as the fungi grow, providing an innovative, sustainable solution to the nitrogen crisis that does not place a heavy burden on agricultural production or the environment.
Everything about publishing science is now digital, except for the price tag. Sjoerd Rijpkema wonders how long this can be sustained.
Vivici is entering the food market by producing high-quality, sustainable protein through precision fermentation. Founded in 2023, Vivici has already made significant progress. The next step is to convince as many customers as possible. ‘The food business is a business based on trust.’
Creaflow is developing a flow plate reactor that is ideal for photochemical and electrochemical processes. It is easy to vary and highly scalable. ‘As a start-up, we were quickly embraced by the market.’
