Nature Communications, Published online: 05 June 2026; doi:10.1038/s41467-026-74020-0 Monitoring structural changes in enzymes is essential for elucidating the mechanisms and dynamics of enzymatic catalysis, however, the transient conformational fluctuations involved in catalytic processes typically occur on microsecond-to-millisecond timescales, posing significant challenges for detection via co…

A new prototype takes mass spectrometry from analyzing a few molecules at a time to handling billions at once. Mass spectrometry is already a cornerstone technology for identifying what molecules are present in a sample and how much of each is there. However, most current instruments still examine molecules one at a time or in [...]

Scientific Reports, Published online: 05 June 2026; doi:10.1038/s41598-026-52414-w Unraveling the corrosion-mitigating action of cyclobenzaprine hydrochloride on carbon steel in acidic media: integrated experimental and multiscale molecular perspectives

Pioneering scientists have created a miniature nuclear fireball and uncovered a surprise discovery in the realm of chemical reactions. Research conducted at Lawrence Livermore National Laboratory sought to fill potential gaps in knowledge of nuclear fallout models, with findings published in Analytical Chemistry. The study examined the behaviour of uranium, cerium, and caesium as these elements u…

Nature Communications, Published online: 03 June 2026; doi:10.1038/s41467-026-73890-8 Iron pentacarbonyl undergoes CO dissociation under UV excitation. While prior works suggested preferential loss of axial ligands, MeV ultrafast electron diffraction experiments show photolysis affects random CO ligands via a Berry pseudorotation.

Phenomenex Inc., a Danaher Company and a global leader in the research and manufacture of advanced technologies for the separation sciences, today introduced the Endrix Long Life LC column, a new liquid chromatography solution engineered for extended column lifetime and consistent performance in demanding analytical workflows

Environmental contamination from heavy metals, pesticides, pharmaceutical residues, per- and polyfluoroalkyl substances (PFAS), and microplastics poses grave risks to human health and ecosystems. Classical analytical methods, including flame atomic absorption spectrometry (FAAS), gas chromatography-mass spectrometry (GC-MS), and high-performance liquid chromatography (HPLC), offer high accuracy b…

This study presents experimental shock tube laser absorption spectroscopy data to validate high-pressure and high-temperature chemical kinetic mechanisms for mixtures of H 2 /air, NH 3 /air, and H 2 /CO/NO 2 /air diluted in argon (95-98%) at high pressures (5, 10, 25 bar) and high temperatures (1000 to 2150 K). The mixtures were at equivalence ratios of 0.5, 1.0, and 1.5 to cover the range of pos…

IntroductionThis research examines the dielectric and electrical properties of binary mixtures of acetaminophen (APAP) with Dimethyl Sulfoxide (DMSO) as a means to comprehend their molecular interactions, polarization behaviour, and charge transport mechanisms that are characteristic of pharmaceutical systems.MethodsThe binary mixtures were examined with the help of a broadband dielectric spectro…

Protein phosphorylation, a key post-translational modification, plays a crucial role in regulating cellular activities in eukaryotes. Dysregulation of phosphorylation is closely linked to the pathogenesis of various diseases Recent advancements in phosphoproteomics have driven substantial improvements in mass spectrometry technologies, enrichment strategies, and data analysis methodologies, there…

We've launched new open-access digital tools to help chemists optimise experiments faster, reduce failed runs and accelerate successful flow chemistry development. The post Flow Chemistry Without the Guesswork: Free New Calculators from Asynt Flow appeared first on Asynt .

The residues of heavy metals, pesticides and mycotoxins in 42 types of traditional Chinese medicine formula granules (TCMFGs) were determined by inductively coupled plasma mass spectrometry (ICP-MS), high-performance liquid chromatography tandem mass spectrometry (HPLC-MS) and gas chromatography tandem mass spectrometry (GC-MS). The results showed that the detection rate of seven types of heavy m…
