Autonomous Charging and Battery Swapping for Unmanned Aerial Vehicles: A Review

open access: yesAdvanced Intelligent Systems, EarlyView.
This review evaluates major autonomous charging and battery swapping methods for unmanned aerial vehicles (UAVs) against a single question: how close each is to sustained unattended operation. Rather than ranking them by charging performance, it identifies the limitation that most restricts each method, and briefly outlines the supporting technologies ...

Diffusion‐Governed Growth Mechanisms of Epitaxial GaAs Islands on CMOS‐Compatible Si(001) Nanotip Arrays

open access: yesAdvanced Physics Research, EarlyView.
The mechanism and kinetics of selective GaAs growth on Si nanotip wafers via nanoheteroepitaxy were investigated as a function of pitch (center‐to‐center nanotip spacing). The pitch dependence reveals distinct surface‐diffusion‐controlled regimes, demonstrating that lateral Ga adatom transport on the SiO2 mask governs material redistribution and ...

Tandem Electrolysers for High‐Efficiency CO2‐to‐Acetate Conversion Driven by Full‐Spectrum Solar Energy

open access: yesCarbon Energy, EarlyView.
A full‐spectrum solar‐driven tandem electrolysis system enables efficient CO2‐to‐acetate conversion by spectrally splitting sunlight and coupling high‐temperature SOEC CO2‐to‐CO electrolysis with ambient CO reduction. The integrated design achieves a solar‐to‐acetate efficiency of 15.8%, demonstrating effective energy‐quality matching for solar carbon ...

Synthesis and Reactivity of Substituted Phosphanylalanes and ‐Gallanes Stabilized by N‐Heterocyclic Carbenes

open access: yesChemistry – A European Journal, EarlyView.
A series of NHC‐stabilized phosphanylalanes and phosphanylgallanes bearing alkyl and aryl substituents at phosphorus was synthesized and characterized. Structural and computational studies reveal how substitution influences E13─P bonding and phosphorus donor properties, while reactions with BH3 demonstrate the accessibility of the phosphorus lone pair ...
