Small, EarlyView.A chelating coordination strategy using ethylenediamine diacetate (EDDA) is introduced to regulate crystallization and passivate defects in Sn–Pb perovskite solar cells. Interfacial coordination at both buried and top surfaces suppresses Sn2+ oxidation, reduces defects, and enhances charge extraction, enabling over 23% efficiency with improved voltage,

Advanced Control Strategy of Back-to-Back PWM Converters in PMSG Wind Power System
Advances in Electrical and Electronic Engineering, 2015 This paper proposes a control scheme of back-to-back PWM converters for the permanent magnet synchronous generator (PMSG) wind turbine system. The DC-link voltage can be controlled at the machine-side converter (MSC), while the grid-side converter (GSC ...

Journal of Clinical Periodontology, EarlyView.ABSTRACT Aim Limited bone support in suprabony defects hinders predictable regeneration, but adjunctive biologics can improve results. This systematic review and meta‐analysis aimed to evaluate the clinical efficacy of adjunctive biologics combined with open flap debridement (OFD) compared with OFD alone when treating suprabony defects.

Periodontology 2000, EarlyView.Abstract Understanding patient responses to periodontal regeneration is crucial. This systematic review and meta‐analysis addressed two key questions: (a) the impact of periodontal regeneration on patient‐reported outcome measures (PROMs) for intrabony and furcation involvement and (b) the cost‐effectiveness of periodontal regeneration for treating ...
