However, these substances are difficult to work with due to their unpleasant smell and oxidizability in air. Now, a research team has found a way to produce sulfinate esters through the direct oxidation of thioesters, which are easily accessible and stable. Their findings will help expand the field of organosulfur chemistry and hopefully lead to new applications in pharmaceuticals.

As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.

Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed themselves. The catalytic reaction usually occurs on the reactive -- and expensive -- metal, but on some catalysts, hydrogen atom-like equivalents literally spill from the metal to the oxide. These hydrogen-on-oxide species are called 'hydrogen spillover.'

Thus, the formation of sulfuric acid in the gas phase directly affects the radiative forcing and Earth's climate. In addition to the known formation from sulfur dioxide, researchers have now been able to demonstrate through experiments that there is another formation pathway that has been speculated about for decades. Sulfuric acid in the atmosphere can also be formed directly by the oxidation of organic sulfur compounds. This new production pathway can be responsible for up to half of the gaseous sulfuric acid formation over the oceans and is thus of high importance for climate projections -- especially over the oceans of the Southern Hemisphere.

Xiaowei Teng, the James H. Manning professor of Chemical Engineering at WPI, has discovered a new redox chemistry empowered by chloride ions for the development of seawater green batteries.

In a new study, a team prompted a popular AI model, ChatGPT, to perform one particularly time-consuming task: searching scientific literature. With that data, they built a second tool, a model to predict experimental results.

The industrial production thereof is mainly performed by means of interfacial polymerization reacting highly reactive phosgene with alcohol at the interface of water and an organic solvent. However, because phosgene is extremely toxic, a synthesis method not employing it has been actively studied from the perspective of safety.

It is usually produced via batch manufacturing, but this multistep process is time-consuming, wasteful and requires very specialized facilities. Now, researchers have manufactured cefazolin using the continuous-flow method. This method is cheaper, quicker, less wasteful and more flexible in terms of how much drug can be produced when it's needed. Improving access to cefazolin is vital for global health and particularly relevant for countries such as Japan, which experienced a shortage in 2019.

A team has made a bio-based polymer blend that's compostable in both home and industrial settings.

The fabric, a blend of plastic and cotton, has been difficult for the industry to separate and therefore recycle. Now, a group of young chemists has invented a green and surprisingly simple solution using a single household ingredient.
