Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

A Bambusuril Receptor Binds Charge Diffuse Anions in Water at Picomolar Concentrations

open access: yesAngewandte Chemie, Volume 137, Issue 37, September 8, 2025.
Synthesis of a bambusuril macrocycle with unprecedented binding affinity for several charge diffuse anions, including iodide, perchlorate, nitrate, and perrhenate, in neutral phosphate buffer is reported. The macrocycle exhibits selectivity for charge diffuse over charge dense anions exceeding seven orders of magnitude.

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

High‐Performance Oxidation and Nanomolar Detection of Phenylhydrazine Using a 6‐Hydroxyflavone‐Based Molecular Electrocatalyst Functionalized Multiwalled Carbon Nanotube in Batch Injection Analysis

open access: yesChemistryOpen, EarlyView.
This study presents a novel, rapid method for in situ functionalization of carbon electrodes using redox‐active form of the 6‐hydroxyflavone. The resulting multiwalled carbon nanotubes with redox‐active HFLA (MWCNT@HFLA‐Redox) electrode enables sensitive, selective detection of toxic phenylhydrazine, with excellent performance (limit of detection: 7 nM)
