Ultrathin indium oxide films show great potential as channel materials of complementary metal oxide semiconductor back-end-of-line transistors due to their high carrier mobility, smooth surface, and low leakage current. However, it has severe thermal stability problems (unstable and negative threshold voltage shifts at high temperatures). In this paper, we clarified how the improved crystallinity of indium oxide by using ultrahigh-temperature rapid thermal O annealing could reduce donor-like defects and suppress thermal-induced defects, drastically enhancing thermal stability.

Metal selenides hold promise as feasible anode materials for potassium-ion batteries (PIBs), but still face problems such as poor potassium storage kinetics and dramatic volume expansion. Coupling heterostructure engineering with structural design could be an effective strategy for rapid and stable K+ storage. Herein, CoSe/MoSe2 heterojunction encapsulated in nitrogen-doped carbon polyhedron and further interconnected by three-dimensional nitrogen-doped carbon nanofibers (CoMoSe@NCP/NCFs) is ingeniously constructed.

Design and manufacture of cathode materials, with suitable pore structure and high electrical conductivity to matching zinc anode, solving the problem of dissolution and structural degradation of cathode materials for zinc ion batteries (ZIBs), is great significance to the development of ZIBs. Herein, Vanadium Nitride (VN) uniformly decorated N-doped micro/mesoporous carbon nanofibers (VN/N-MCNF) with appropriate porous and reactive sites for Zn2+ is prepared by using V-MOF, as important precursor via electrostatic spinning and pyrolysis technique. As a cathode electrode for ZIBs, the VN/N-MCNF is suitable for diffusion and adsorption of large-sized solvated structured [Zn(H2O)6]2+, for its abundant micro/mesoporous structure and good electrical conductivity.

Pathogen bacteria appear and survive on various surfaces made of steel or glass. The existence of these bacteria in different forms causes significant problems in healthcare facilities and society. Therefore, the surface engineering of highly potent antimicrobial coatings is highly important in the 21st century, a period that began with a series of epidemics.

Aiming at the problems of scarce datasets and the low identification accuracy faced in the field of weld-crack detection, this paper proposes an artificial-weld-crack preparation method based on the doping of dissimilar metal particles to augment the number of samples of weld-crack defects. Meanwhile, data augmentation methods such as random cropping, scaling and Mosaic are combined to further enhance the richness of the samples, so as to provide strong data support for the proposed weld-crack-defect detection model. Given the limitations of storage and computational resources in industrial application scenarios, this paper designs the lightweight detection network YOLOv6-NW.
