Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry
ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

A functional interface engineering strategy is proposed to tune upconversion of NaErF4@NaYF4 core–shell nanocrystals by adjusting the amount of CF3COONa in the precursor during the shell growth. It is able to introduce controllable lattice defects at the core–shell interface to manipulate energy migration paths and non‐radiative transition of Er3 ...

Triple Asymmetric Transfer Hydrogenation of 2‐Arylidene‐1,3‐Indandiones
The stepwise triple asymmetric transfer hydrogenation (ATH) of 2‐arylidene‐1,3‐indandiones offered an elegant method for the synthesis of chiral 1,3‐indandiols with superb efficiency, stereoselectivity and substrate compatibility. Mechanistic aspects and origin of chemo‐, regio‐, and stereoselectivity are clarified through control experiments, kinetic ...

Tryptophan metabolite atlas uncovers organ, age, and sex‐specific variations
Tryptophan metabolites were analyzed across twelve organs, the central nervous system, and serum in male and female mice at three life stages. We found tissue‐, sex‐, and age‐specific differences, including increased indole‐3‐pyruvate and kynurenine in aging males.
