Pressure‐Induced Topochemical Reconstruction for Quenchable Metastable ZnIn 2 S 4 With Enhanced Photoelectric Effect for Artificial Synapses Application

ABSTRACT Layered ternary sulfide ZnIn 2 S 4 is an attractive visible‐light semiconductor for photodetection, photocatalysis, and neuromorphic optoelectronics, but its photoelectric output is limited by inefficient carrier separation and sluggish carrier dynamics. Pressure offers...

Preparation methods, mechano-bactericidal performance and mechanisms of Ti-based nanostructure arrays: A review

Medical titanium (Ti) and its alloys have been widely employed in biomedical field, but Ti-based implants are prone to bacterial biofilm contamination, leading to implant failure. Nanostructure arrays, as a new strategy, exhibit effective bactericidal performance and biofilm inhi...

How Do Human Land Use Changes and Ecological Restoration Drive Ecological–Economic–Social Coupling Coordination Across the Yellow River Basin in China?

Conflicts between intense human activity and fragile ecosystem protection have and will continue to affect the ecological–economic–social complex system across the Yellow River Basin. An enhanced understanding of the effects of human land use changes and ecological restoration on...

HZO thickness-dependent charge loss mechanisms in HfO2-based MIFIS FeFETs

Hafnium-based ferroelectric field-effect transistors (FeFETs) with metal/gate interlayer/ferroelectric/channel interlayer/silicon (MIFIS) gate stacks are a promising candidate for high-density 3D NAND. However, the severe retention degradation hinders their application, and the d...

Exogenous spermidine and the CaSPDS gene regulate salt tolerance by maintaining ROS homeostasis and photosynthetic function in pepper seedlings

Salt stress severely restricts pepper ( Capsicum annuum L.) growth and productivity by disrupting osmotic balance, damaging the photosynthetic system, and inducing excessive reactive oxygen species (ROS) accumulation. Spermidine (Spd), an important polyamine, plays critical roles...

Synergistic Grain Refinement and Insulating Phase Formation via Zr4+ Doping for Low-Loss Colossal Permittivity in (In,Nb) Codoped TiO2 Ceramics

Abstract Colossal permittivity (In,Nb) codoped TiO2 ceramics are promising for microelectronic applications but suffer from high low-frequency dielectric loss primarily due to leakage currents across grain boundaries. This work demonstrates that Zr4+ doping at Ti-sites in (In0.5N...

Cervical small-cell neuroendocrine carcinoma mixed with squamous cell carcinoma first suspected on liquid-based cytology and confirmed by biopsy: a case report

Cervical small cell neuroendocrine carcinoma (SCNEC) admixed with squamous cell carcinoma (SCC) is a rare malignancy associated with a poor prognosis. While histological features of this mixed tumor have been described, liquid-based cytology (LBC) findings remain largely undocume...

Glutathione functionalized selenium nanoparticles suppress colorectal cancer cell growth with mitochondrial dysfunction and mitophagy related remodeling
