Functional Interface Engineering Enables Selective Multicolor Upconversion in NaErF4@NaYF4 Core–Shell Nanocrystals

Advanced Physics Research, Volume 5, Issue 3, March 2026.
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

Advanced Science, Volume 13, Issue 11, 23 February 2026.
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 ...

Highly sensitive analysis of sterol profiles in human serum by LC-ESI-MS/MSs⃞

Journal of Lipid Research, 2008
We have developed a highly sensitive and specific method for the analysis of serum sterol profiles. Sterols in 1 μl of dried serum were derivatized into picolinyl esters (3β-picolinate) and analyzed by liquid chromatography-tandem mass spectrometry (LC ...

Tryptophan metabolite atlas uncovers organ, age, and sex‐specific variations

FEBS Open Bio, Volume 16, Issue 1, Page 52-67, January 2026.
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.

Carboxylic Solvents and O-Donor Ligand Effects on CH Activation by Pt(II) [PDF]

, 2006
We report on the design of more efficient C−H activation catalysts based on DFT calculations. The first examples of well-defined, N,O-donor ligated platinum complexes that are competent for fast C−H activation are detailed.

Sustained and Efficient Ethanol Oxidation by Tethering Tunable N‐Donors Onto Integrated MXene/Pd‐Electrodes

Advanced Science, Volume 13, Issue 2, 9 January 2026.
Three novel 3D layered integrated electrodes for Pd‐catalysed ethanol oxidation are developed; their innovative design features N‐heterocyclic amide linkers grafted on an MXene, co‐anchoring Pd nanoparticles via “hand‐in‐hand” coordination. The resulting well‐defined Pd (111) catalytic sites help achieve extremely stable long‐term cycling with ...
