Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

Carbon Nanopatch‐Decorated Defect‐Rich Regions for Stable Zinc Metal Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To improve the stability of Zn anodes, a carbon‐nanopatch strategy based on candle‐flame pyrolysis is proposed. After rinsing, carbon nanoparticles are mainly retained in defect‐rich regions on the Zn surface, where they help alleviate local field intensification, improve interfacial uniformity, and mitigate parasitic reactions.

Piezosurgical partial ostectomy of the incisive bone for an ossifying fibroma removal in a 4‐year‐old Warmblood gelding

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Ossifying fibromas are uncommon in horses and complete surgical excision with premaxillectomy, maxillectomy or mandibulectomy is recommended. Piezosurgery has been previously used in equines only in one study. Objective To report a case of ossifying fibroma treated with piezosurgery and to describe its follow‐up.
