Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Cyanoacetamidobetaine—A Zwitterionic Nitrile Derivative

ChemistryOpen, EarlyView.
The reaction of sodium dicyanamide with betainium chloride in aqueous solution affords N‐cyano‐2‐(trimethylammonio)acetaminide (cyanoacetamidobetaine). Single crystal X‐ray diffraction reveals a monoclinic structure comprising a trimethylammonium head group connected to a cyanoacetaminide unit via a methylene bridge.

Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery

Journal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.
This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...

Pure Chitosan Microfluidic Spinning Affords Modular Core‐Sheath Fibers and Hand‐Crafted Scaffolds with Enhanced Fibroblast Compatibility

Small, EarlyView.
Microfluidic Wet Spinning affords highly resilient and biocompatible microfibers of pure chitosan without the use of any crosslinker. We produced microfibers both sheath and core of made of chitosan and another version with a chitosan sheath and chitin nanocrystals in the core.

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

Small, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.
