Dual sulfur sources redox dynamics guided growth of 〈hk1〉-oriented SbS microrods: lattice strain modulation for ultra-low dark current.

Antimony trisulfide (SbS) has emerged as a promising inorganic semiconductor for optoelectronics due to its distinctive anisotropic crystal structure and suitable bandgap (∼1.7 eV). While hydrothermal synthesis remains challenging for achieving high crystallinity and controlled morphology, we developed an innovative dual‑sulfur precursor strategy utilizing sodium thiosulfate (STS) and thioacetamide (TAA) at a 7:2 M ratio with SbCl.

Mitigating Effect of Ginger Extract on Survival Rate and Muscle Quality of Crucian Carp () Under Transportation Stress.

This study evaluated the effects of ginger extract, applied via four methods-direct addition, microencapsulation, and combinations with NaCl or eugenol-on stress responses and muscle quality in crucian carp during transportation. Among the treatments, microcapsules and the eugenol compound showed the best results, each achieving a 50% survival rate after 72 h. The microcapsule group provided prolonged antioxidant protection, stabilized water quality, reduced cortisol levels, suppressed pro-apoptotic gene expression (, , , , , and ), while upregulating the anti-apoptotic gene .

A High-Performance All-Carbon Diamond Pixel Solar-Blind Detector with In Situ Converted Graphene Electrodes.

Solar-blind ultraviolet detectors, known for their low background noise and high sensitivity, have garnered significant attention in various applications such as space communications, ozone layer monitoring, guidance applications, and flame detection. Pixel photodetectors, as the cornerstone of imaging technology in this field, have become a focal point of research in recent years.

The Influence of Process Parameters on Hydrogen-Terminated Diamond and the Enhancement of Carrier Mobility.

With the development of diamond technology, its application in the field of electronics has become a new research hotspot. Hydrogen-terminated diamond has the electrical properties of P-type conduction due to the formation of two-dimensional hole gas (2DHG) on its surface. However, due to various scattering mechanisms on the surface, its carrier mobility is limited to 50-200 cm/(Vs).

Enhanced Photoelectrochemical Water Splitting of Black Silicon Photoanode with pH-Dependent Copper-Bipyridine Catalysts.

Since the water oxidation half-reaction requires the transfer of multi-electrons and the formation of O-O bond, it's crucial to investigate the catalytic behaviours of semiconductor photoanodes. In this work, a bio-inspired copper-bipyridine catalyst of Cu(dcbpy) is decorated on the nanoporous Si photoanode (black Si, b-Si). Under AM1.

Coherent nanoscale cobalt/cobalt oxide heterostructures embedded in porous carbon for the oxygen reduction reaction.

Cost-effective and efficient electrocatalysts for the oxygen reduction reaction (ORR) are crucial for fuel cells and metal-air batteries. Herein, we report the facile synthesis of a Co/CoO/CoO heterostructure embedded in a porous carbon matrix by refluxing and annealing. This composite exhibits several structural merits for catalyzing the ORR: (1) the existence of metallic Co and graphitic carbon enhanced the electrical conduction; (2) the porous, loose carbon network facilitated the electrolyte permeation and mass transport; (3) more importantly, the nanosized coherent CoO/CoO heterojunctions with structural defects and oxygen vacancies enhanced the charge transport/separation at the interface and adsorption affinity to O, thus promoting the ORR kinetics and lowering the reaction barrier.

Classic and conventional procedures in molecular cloning are inherent compositions in modern molecular biological experiments and are frequently involved in daily laboratory activities. They take up the majority of the total time input in spite of the availability of well-designed specialized commercial kits. A similar situation is also in the field of biotechnology.

Genome-wide analysis of microRNAs and their target genes related to leaf senescence of rice.

Grain production of rice (Oryza sativa L.) is a top priority in ensuring food security for human beings. One of the approaches to increase yield is to delay leaf senescence and to extend the available time for photosynthesis.

Tunable p-type conductivity and transport properties of AlN nanowires via Mg doping.

Arrays of well-aligned AlN nanowires (NWs) with tunable p-type conductivity were synthesized on Si(111) substrates using bis(cyclopentadienyl)magnesium (Cp(2)Mg) vapor as a doping source by chemical vapor deposition. The Mg-doped AlN NWs are single-crystalline and grow along the [001] direction. Gate-voltage-dependent transport measurements on field-effect transistors constructed from individual NWs revealed the transition from n-type conductivity in the undoped AlN NWs to p-type conductivity in the Mg-doped NWs.
