Stronger Hydrogen Bonds Found in Microhydrated Nitrous Acid Clusters Our latest research explores the strength of hydrogen bonds in microhydrated clusters of Nitroxyl acid (HNO) and nitrous acid (HONO). The study reveals that HONO forms stronger hydrogen bonds with water molecules compared to HNO. This can be attributed to the higher acidity of the proton in HONO. The findings also suggest that cooperative interactions play a significant role in HONO-water clusters, leading to more stable configurations. This research has implications for understanding atmospheric chemistry and the behavior of these molecules in biological environments. #hydrogenbonding #Nitroxyl #nitrousacid #nitricacid #computationalchemistry #njc #newjouranalofchemistry #RSC #RSCphys

The combined effort of our #TeamSolenis experts in Antwerp, Mönchengladbach and Wilmington, together with the NMR department of the University of Delaware, has led to the publication of an article in the esteemed journal of American Chemical Society Analytical Chemistry: https://lnkd.in/ge7Fj33R 📜 🔬 Our article addresses the need for more robust and/or complementing analytical techniques on PFAS (perfluoroalkyl substances) in consumer and food packaging materials. 📦 Current methods can over- or underestimate the levels of PFAS detected and therefore can exclude possible alternatives on the market, or worse: allow PFAS containing packaging on the market without being fully detected. 😱 🙅♂️ By using Fluorine-19 Solid-State Nuclear Magnetic Resonance Spectroscopy, we can differentiate signals of distinctive fluorinated sources without the need of sample clean up and therefore provide direct evidence of the presence or absence of PFAS. 🔎🕵♂️ Thanks to Solenis for giving me the opportunity of exploring the science behind this business case further and to write this article about it. A big thanks to my co-authors Ernie Laletas, Caitlin Quinn, Subbu V Raguraman, Patric Bierganns and Brian Carr for their contributions in every way possible. 🙏 🙏 🙏 #paper #packaging #foodpackaging #burgerwrap #barriercoating #consumerpackaging #PFAS #Solenis #UDel #TOF #NMR #ACS #analyticalchemistry

New capabilities of MION2-Orbitrap Exploris system demonstrated Recently, our team developed a novel method for operating the #MION2 Orbitrap Exploris™ system, enabling highly sensitive analysis of a wide range of chemicals in complex gas mixtures, such as ambient air. This approach uses high-pressure adduct-forming chemical ionization for detecting polar, more functionalized compounds, and low-pressure chemical ionization for less functionalized, weakly polar compounds, all in one system. In the pre-print published on #ChemRxiv, our scientists and engineers, together with our academic collaborators, introduce and demonstrate the concept of Multi-Pressure Chemical Ionization (MPCI). This method combines capabilities that currently require multiple mass spectrometry systems.

A novel reactivity toward C–F bond functionalization has been developed, which could be designated as fluorine atom transfer (FAT). A photoexcited state of an N-heterocyclic carbene-ligated boryl radical exhibits a transcendent reactivity, capable of activating chemically inert carbon–fluorine bonds through homolysis. Combined experimental and computational studies suggest that the ligated boryl radical species directly abstracts a fluorine atom from the organofluoride substrates to provide valuable carbon-centered radicals.

Two recent papers. The first one is an in-depth study of silanization that helps minimizing cation sorption on vials during tracer experiments. The second paper presents the new thermodynamic data associated with the complexation of Tc(IV) with chloride ions. https://lnkd.in/ggvcpk4F https://lnkd.in/gfswbcFY

Congratulations to the authors of Chiral Quaternary Ammonium Salt-Catalyzed Enantioselective Addition Reactions of Hydantoins. We are pleased that our UniPol Polarimeter L1000 was involved in this important research work, where the researchers not only developed a protocol for the 1,4-addition of hydantoins to various Michael acceptors but also elucidated crucial aspects regarding the interaction between catalysis and hydantoins. Additionally, they provided a first proof of concept for the ammonium salt- catalyzed -sulfanylation of hydantoins in their pursuit of enhancing enantioselectivities. Here you can find the document: https://buff.ly/42afpm0 Here you can find our new UniPol V Polarimeter: https://buff.ly/3Gm0xqO We wish you best luck and success in your further researches! #SchmidtHaensch #Polarimeter #UniPol #Application
