Semiconductor photocatalyst helps to realize borylation reaction
Credit: Angewandte Chemie International Edition (2023). DOI: 10.1002/anie.202306846 A research group led by Prof. Dai Wen from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has realized borylation reactions involving N-heterocyclic carbene boranes (NHC-BH3) with a simple and efficient heterogeneous photocatalytic system, enabling synthesis of high-value transformations including hydroboration…

Mandatory events aren’t relaxing | Careers
If you’re not a fan of HR blogs, you might not have heard of this year’s supposed hot workplace trend: proactive rest. This can mean a variety of different things, but it essentially boils down to employers trying to give their employees some kind of break before they burn out. The concept seems to be…

Quantum Device Used To Slow Down Chemical Reaction by 100 Billion Times
Scientists at the University of Sydney used a quantum computer to slow and directly observe a key chemical reaction process, unveiling details previously unseen due to rapid timescales. This breakthrough offers new insights for materials science, drug design, and other fields. What happens in femtoseconds in nature can now be observed in milliseconds in the…

Research team clarifies mode of action of cannabinoids in inflammation
Graphical abstract. Credit: Cell Chemical Biology (2023). DOI: 10.1016/j.chembiol.2023.08.001 While the German government is planning to relax legislation on the use of cannabis, researchers from the Friedrich Schiller University Jena, together with colleagues from Italy, Austria and the U.S., have identified the mode of action underlying anti-inflammatory effects demonstrated by cannabinoids. A few… Continue Reading…

Researchers break down, rebuild polyurethane to make new foam
Credit: Macromolecules (2023). DOI: 10.1021/acs.macromol.3c01116 Polyurethane plastics are ubiquitous, used everywhere from mattresses to shoes. But once these products are no longer wanted, these materials litter landfills and oceans across the world. Now, a group of researchers at Northwestern University has developed a new recycling method for polyurethane foams, one of the most common types…

Overcoming the challenges to synthesising iron–sulfur proteins outside the glovebox
Iron-sulfur (Fe-S) proteins, essential to all life forms, are difficult to synthesise due to the complicated molecular machinery involved and sensitivity of Fe-S clusters to oxygen. In a new study, a team of researchers devised an innovative protocol for synthesising mature Fe-S proteins, by bringing together a recombinant sulfur assimilation (SUF) system and an oxygen-scavenging…

A first for ferrocene: Organometallic capsule with unusual charge-transfer interactions
Ferrocene is an emergent organic-metal hybrid compound, and its accidental discovery has led to the rapid development of organometallic chemistry. Aside from its interesting structure, which consists of an iron atom sandwiched between two pentagonal organic rings, ferrocene has remarkable redox-responsive properties. Simply put, one can make ferrocene-based compounds reversibly switch between different oxidation states…

Enhanced chemical weathering: A solution to the climate crisis?
The Earth is getting hotter and consequences have been made manifest this summer around the world. Looking back in geological history, global warming events are not uncommon: Around 56 million years ago, during the period known as the Paleocene-Eocene Thermal Maximum (PETM), the temperatures rose by an average of 5 to 8 degrees Celsius. This…
