Exploring the Impedance Spectroscopy in Hole‐Conductor‐Free Mesoscopic Perovskite Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study employs impedance spectroscopy (IS) to investigate the carrier dynamics of printable perovskite solar cells (p‐MPSCs). The exceptional stability of p‐MPSCs enables reliable IS measurements under various conditions. We develop an equivalent circuit model to analyze the IS data, linking each circuit element to specific dynamic processes.

Using expert elicitation to predict feral cat, Felis catus, responses to management

open access: yesPest Management Science, EarlyView.
We generated estimates of lethal feral cat management success for 864 scenarios, only 71 lethal management scenarios met a population reduction target of 57%. Cat‐targeted poison baits, in dry conditions and arid areas were most successful. Feral cat management requires continued adaptive strategies to reduce cat impacts.

A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.
