Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie International Edition, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Nanoscale Thermal Transport in Bi2(Te, Se)3 Thermoelectric Material Using Pulsed STEM

open access: yesAdvanced Physics Research, EarlyView.
The pulsed‐STEM technique enables simultaneous acquisition of crystallographic, compositional, and thermal transport information within a single experiment. In anisotropic Bi2(Te, Se)3, phase‐delay imaging visualizes directional heat flow and interfacial resistance at the nanoscale, offering a new approach to understanding and designing thermoelectric ...
