Difluoro Carbenes: From Genuine Gold Complexes to Unprecedented Metallacyclic Reactivity
Angewandte Chemie, Volume 137, Issue 46, November 10, 2025.Thanks to chelating ligands and enhanced backdonation, genuine gold(I) difluorocarbenes persistent for hours at −30 °C or even 0 °C have been obtained. In addition to classical Fisher‐type electrophilic behavior, these complexes display unprecedented reactivity toward alkenes and 1,3‐dienes.

High‐Resolution Elemental Analysis of Neuromelanin‐Containing Organelles in Human Locus Coeruleus
Journal of Neurochemistry, Volume 170, Issue 7, July 2026.Created in https://BioRender.com. Neuromelanin (NM), a dark metal‐chelating pigment in the brain, has long been of interest for its potential roles in aging and Parkinson's disease. In this study, we explored NM‐containing neurons (NM neurons) in the human locus coeruleus at unprecedented resolution.

Addressing Bottlenecks to Achieve High‐Energy Sodium‐Ion Cells Using Tin Anodes
Advanced Energy Materials, Volume 16, Issue 17, 6 May 2026.The challenges in coupling high voltage cathode with Sn‐alloying anode or in anode‐free cell, using glyme based electrolytes to realize high energy Na‐ion cells are reported. Surface protection strategy such as SnO coating on Sn or trapping the parasitic species from poisoning the anode, helps improving the cyclability, with ∼100% capacity retention ...
