The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Domain‐Wall Circulation Gating and Pinning via Compositional Engineering of Cylindrical Nanowires

Small, EarlyView.
Cylindrical magnetic nanowires offer a promising platform for future three‐dimensional spintronic devices. By strategically engineering nanometer‐scale chemical modulations, a novel circulation gate is established to control domain wall propagation.

The baryonic phase in holographic descriptions of the QCD phase diagram

, 2012
We study holographic models of the QCD temperature-chemical potential phase diagram based on the D3/D7 system with chiral symmetry breaking. The baryonic phase may be included through linked D5-D7 systems. In a previous analysis of a model with a running

Direct Access to Chiral Piperidines by Enantioselective HAT‐Initiated C(sp3)─H Oxidation

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
The direct desymmetrization of piperidines is achieved through manganese‐catalyzed enantioselective α‐C(sp3)─H oxidation with hydrogen peroxide, affording versatile chiral N,O‐acetals in good yields and with high enantio‐ and diastereoselectivity. These intermediates provide access to diverse functionalized piperidines with retention of chirality ...

Recent Advances in Reversed‐Phase Liquid Chromatography for Therapeutic Oligonucleotide and Conjugate Characterization: From Ion‐Pairing to Green Analytical Approaches

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Therapeutic oligonucleotides (ONs) have rapidly emerged as a novel class of treatments in the pharmaceutical industry, with over 25 medicines approved in the past decade. Ion‐pair reversed‐phase liquid chromatography coupled with mass spectrometry (IP‐RPLC‐MS) is widely used method for ON characterization.
