3D‐Printed Titanium Implants with Bioactive Peptide‐Polysaccharide Scaffolds for Personalized Bone Reconstruction

Advanced Healthcare Materials, EarlyView.
Porous 3D‐printed titanium implants are made bioactive by integration with a supramolecular peptide‐hyaluronic acid nanofibrillar scaffold, without the addition of exogenous cells or growth factors. Uniform filling of the implant architecture promotes vascularized, spatially homogeneous bone regeneration, significantly enhancing osteogenesis throughout

Aggregation‐Induced Emission Molecular Design for Mitigating Non‐Radiative Energy Loss in Organic Solar Cells

Advanced Materials, EarlyView.
Aggregation‐induced emission strategy is first used to overcome aggregation‐caused quenching in Y‐series acceptors. By integrating tetraphenylethylene, the dTPE exhibits three‐fold PLQY enhancement and significantly suppressed non‐radiative energy loss. An ultra‐low Eloss of 0.130 eV and a record VOC of 0.93 V are achieved, resulting in a PCE over 20.5%

Selective harmonic elimination pulse width modulation based hybrid multilevel inverter topology with reduced components

IET Power Electronics, EarlyView., 2022
Abstract In this paper, a reduced switch count single‐phase hybrid multilevel inverter (MLI) is presented. Level generation unit (LGU) and polarity changing unit (PCU) are the two parts of the presented topology which are connected in series. Other advantages of the proposed topology include the reduced switch count, higher level generation with ...
