Direct evidence for strong crossover of collective excitations and positive sound dispersion in the supercritical state [PDF]
J. Phys.: Condens. Matter 28 43LT01 (2016), 2015 Supercritical state has been viewed as an intermediate state between gases and liquids with largely unknown physical properties. Here, we address the important ability of supercritical fluids to sustain collective excitations. We directly study propagating modes on the basis of correlation functions calculated from extensive molecular dynamics ...

ELECTROPHORESIS, Volume 43, Issue 23-24, Page 2334-2350, December 2022., 2022 Abstract The analytical requirements for food testing have increased significantly in recent years. On the one hand, because food fraud is becoming an ever‐greater challenge worldwide, and on the other hand because food safety is often difficult to monitor due to the far‐reaching trade chains.

Metal‐Free, Selective Ortho‐Deuteration of N‐Heterocyclic Oxides
Advanced Synthesis &Catalysis, EarlyView.Abstract Replacing hydrogen with deuterium raises the activation energy for C−D bond cleavage. This approach has gained attention in drug design, especially to protect the ortho‐position of pyridines, which are susceptible to enzymatic oxidation.

Angewandte Chemie, EarlyView.A tandem process was developed to convert polyethylene (PE) into n‐alkanes by coupling PE hydrogenolysis with methanol aqueous phase reforming (APR). Utilizing a bimetallic Ru−Pt/TiO2 catalyst, the process achieved 85.1 % PE conversion and 81.0 % selectivity toward liquid fuels and lubricant oils, reducing reliance on fossil fuels through eco‐friendly ...

Ferrocene derivatives with planar chirality and their enantioseparation by liquid‐phase techniques
ELECTROPHORESIS, Volume 44, Issue 1-2, Page 158-189, January 2023., 2023 Abstract In the last decade, planar chiral ferrocenes have attracted a growing interest in several fields, particularly in asymmetric catalysis, medicinal chemistry, chiroptical spectroscopy and electrochemistry. In this frame, the access to pure or enriched enantiomers of planar chiral ferrocenes has become essential, relying on the availability of ...
