Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

A Large Magneto‐Optical Trap of Cadmium Atoms Loaded From a Cryogenic Buffer Gas Beam

open access: yesNatural Sciences, EarlyView.
We demonstrate laser cooling and trapping of cadmium atoms using deep‐ultraviolet light at 229 nm, capturing more than 1×107$1\times10^{7}$ atoms within 10 ms from a compact 5 cm Zeeman slower and cryogenic beam source. We achieve peak densities of 2.5×1011cm−3$2.5\times10^{11} \,\text{cm}^{-3}$ and phase‐space densities of 2×10−9$2\times10^{-9}$.

Ruthenium‐Catalyzed CH Alkenylation of Trypanocidal Naphthoquinones: A Mechanistic Benchmarking Study

open access: yesChemistryOpen, EarlyView.
Computational roadmap to click‐ready quinones. Quantum chemical analysis reveals how substituents modulate the reactivity of trypanocidal naphthoquinones in Ru‐catalyzed CH alkenylation, guiding the design of sulfonyl‐fluoride scaffolds for next‐generation antiparasitic agents.
