The formation of a new exporanet can cause chemical inconsistencies in paired stars
Image of a protoplanetary disc from Alma. Credit: Alma (ESO/NAOJ/NRAO) A common star, or star traveling together, can provide insight into the processes that other stars cannot. Differences in brightness, trajectory and chemical composition suggest a variety of characteristics, and scientists are beginning to misuse them. A new paper by researchers from Australia, China, the US and Europe was submitted…

Chemical Recycle Turn turns silicone into pure building blocks and promising infinite reuse
A general strategy for chemical recycling of silicon polymers. Credit: nAm’cứcvũet al Research conducted by CNRS researchers explains new ways to recycle silicon waste (caulking, sealants, gels, adhesives, cosmetics, etc.). It could significantly reduce the environmental impact of the sector. This is the first universal recycling process that returns all kinds of spent silicon materials to their previous state in…

Microscopy breaks the barriers to nanoscale chemical imaging
SIMIP enables high-resolution images rich in both chemical and spatial information. Quantum cascade lasers (QCLs) excite molecular vibrations, while spatial light modulators (SLMs) produce striped light patterns projected onto the sample. Scientific CMO (SCMOS) cameras capture modulated fluorescent signals. It is processed using Hessian SIM and sparse deconvolution algorithms to generate high-resolution chemical and structural images. Subtracting the hot image…

Artistic single-atom catalysts can enable sustainable chemical and pharmaceutical synthesis
a) Rational design of ASACs for cross-linking reactions. M1 represents a foreign single metal atom introduced into a reducing carrier. (b) As a representative example, using a single atom of PD1 fixed to the material CEO2, this panel illustrates the evolution of the dynamic structural and valence states of the PD1 ASAC. These changes help to avoid the usual challenges…

“Democratic Chemistry Analysis”: Using machine learning and robotics to identify chemical compositions from images
Microscopic images of potassium nitrate. Credit: Oliver Steinbock A chemist at Florida State University has created a machine learning tool that can identify the chemical composition of a dry salt solution from an image with 99% accuracy. By preparing thousands of samples and artificial intelligence using robotics to analyze the data, we created a simple and inexpensive tool that expands…
