Negative Enthalpy Doping Stabilizes P2-Type Oxides Cathode for High-Performance Sodium-Ion Batteries.

P2-type NaNiMnO (NNMO) as cathode material for sodium-ion batteries (SIBs) largely suffers from continuous accumulation of local stress caused by destructive structural evolution and irreversible oxygen loss upon cycling, leading to rapid capacity degradation. Herein, a strategy of negative enthalpy doping (NED), wherein transition metal (TM) sites are substituted with 0.01 mol each Sn, Sb, Cu, Ti, Mg, and Zn to increase the stability of the TM layers, is proposed.

The Frequency Response Characteristics of Ge-on-Si Photodetectors Under High Incident Power.

This study explores the mechanisms responsible for the bandwidth reduction observed in germanium photodetectors under high signal light power. We investigate the impact of the carrier-shielding effect on the bandwidth through simulations, and we mitigate this effect by increasing the applied bias voltage. The increase in the concentration of photogenerated carriers leads to a reduction in the carrier saturation drift velocity, which reduces the bandwidth of the germanium photodetector; this phenomenon is studied for the first time.

This study addresses the inherent limitations of perovskite crystal growth by designing a novel strategy for near-equilibrium growth system to maintain optimal conditions throughout the process.

Management of pediatric femoral neck fractures from classification to surgery: a review of indications based on anatomic and radiographic features of the proximal femur.

This review focuses on the anatomic and radiographic characteristics of the pediatric proximal femur and the advantages and disadvantages of different protocols for the management of pediatric femoral neck fractures (PFNFs) in terms of fracture classification, reduction methods, reduction quality and fixation methods, with the goal of proposing an optimal treatment protocol for PFNFs to reduce the incidence of postoperative complications. The anatomic and radiographic characteristics of the pediatric proximal femur, including the presence of an active growth plate, an immature femoral calcar, greater trabecular density and plasticity and a relatively immature blood supply are very different from those of the adult proximal femur. Treatment protocols for PFNFs must differ from those for adult femoral neck fractures.

However, whether Se can counteract As-induced endothelial dysfunction through ferroptosis remains unclear.

Tailoring Versatile Nanoheterojunction-Incorporated Hydrogel Dressing for Wound Bacterial Biofilm Infection Theranostics.

Wound-infected bacterial biofilms are protected by self-secreted extracellular polymer substances (EPS), which can confer them with formidable resistance to the host's immune responses and antibiotics, and thus delays in diagnosis and treatment can cause stubborn infections and life-threatening complications. However, tailoring an integrated theranostic platform with the capability to promptly diagnose and treat wound biofilm infection still remains a challenge. Herein, a versatile erbium-doped carbon dot-encapsulated zeolitic imidazolate framework-8 (Er:CDs@ZIF-8) nanoheterojunction (C@Z nano-HJ) is tailored and incorporated into gelatin methacrylate/poly(-hydroxyethyl acrylamide) (GelMA/PHEAA)-based tough and sticky hydrogel dressing (GH-C@Z) to achieve wound biofilm infection-integrated theranostic application.

Fine-tuning of Wnt signaling by RNA surveillance factor Smg5 in the mouse craniofacial development.

The specific roles of nonsense-mediated mRNA decay (NMD), a translation-dependent RNA quality control mechanism that degrades mRNAs containing premature termination codons (PTCs), in mammalian craniofacial development have remained unclear. Here, we show that knockout of the essential NMD factor in mouse craniofacial neural crest cells leads to hypoplastic mandibles, subsequently inducing tongue mispositioning and cleft palate formation. Furthermore, loss triggers massive cell apoptosis and disrupts cell differentiation, accompanied by widespread alterations in alternative splicing and a surge in PTC-containing mRNA levels.
