Artificial intelligence could ‘revolutionise’ chemistry but researchers warn of hype | News
Artificial Intelligence can revolutionise science by making it faster, more efficient and more accurate, according to a survey of European Research Council (ERC) grant winners. And while the report looks at the impact of AI on all scientific fields, the field of chemistry, in particular, can be expected to benefit greatly from the revolution, say…

Pharmaceuticals roundup 2023 | Business
Legislation caused consternation for the pharmaceutical industry in both the EU and the US in 2023. First, the EU’s delayed draft pharmaceutical legislation was finally published in late April. Notable proposals include a reduction in the number of scientific committees at the European Medicines Agency (EMA). The EMA would have to be notified more quickly…

Chemicals roundup 2023 | Business
The chemical sector racked up losses this year as it came up against a cluster of challenges including high operating costs, low demand and an overabundance of production capacity. The year was particularly brutal in Europe where inflation and energy prices crimped demand for chemicals. In response to evaporating earnings, companies settled firmly into…

New Technique Allows Diapers To Be Recycled 200 Times Faster
Superabsorbers become liquid under UV light after they have taken up sufficient water. Then, they can be reused. Credit: Ken Pekarsky, KIT Water and UV radiation effectively and swiftly break down the crosslinked polymers in diaper liners without the use of any chemicals. This process allows the recycled plastic molecules to be repurposed for diverse…

Fast flow-chemistry set-up facilitates sulfur-fluoride click chemistry | Research
A fast flow chemistry method makes the production of sulfuryl fluoride quicker and safer. This gaseous reagent is useful in the synthesis of click-ready reagents, then easily functionalised into a myriad of chemical compounds, including peptides and proteins. Most reactions take place in less than two minutes, in a site-selective manner – a great opportunity…

Enhanced photocatalytic degradation of methylene blue dye using eco-friendly synthesized rGO@ZnO nanocomposites
Characterization of synthesized materials Optical properties Experiments were conducted using a UV–Visible spectrophotometer to examine the optical characteristics of G, GO, rGO, ZnO, and rGO@ZnO NCs (Fig. 4). G, GO, and rGO were dispersed in deionized water, and G demonstrated an absorption peak near 270 nm. Subsequently, the oxidation of G to GO was ascribed to the…

First discovery of charcoal-based prehistoric cave art in Dordogne
A large number of Carbon (charcoal)-based black graphical entities was discovered by our team between the 27th and the 29th of February 2020 in the décor of the main galleries of the Font-de-Gaume cave, Dordogne, Southern France. The Dordogne is one of the world’s richest regions in terms of decorated Paleolithic caves such as the…

Resource-efficient and climate-friendly with sodium-ion batteries
The transition to a society without fossil fuels means that the need for batteries is increasing at a rapid pace. At the same time, the increase will mean a shortage of the metals lithium and cobalt, which are key components in the most common battery types. One option is a sodium-ion battery, where table salt…
