Abstract In view of increasing drug resistance, ecofriendly photoelectrical materials are promising alternatives to antibiotics. Here we design an interfacial Schottky junction Bi 2 S 3 /Ti C T x resulting from the contact potential difference between Ti and . The different work functions induce formation a local electrophilic/nucleophilic region. self-driven charge transfer across interface increases electron density on formed barrier inhibits backflow electrons boosts separation....
Abstract Biofilms have been related to the persistence of infections on medical implants, and these cannot be eradicated because resistance biofilm structures. Therefore, a biocompatible phototherapeutic system is developed composed MoS 2 , IR780 photosensitizer, arginine–glycine–aspartic acid–cysteine (RGDC) safely eradicate biofilms titanium implants within 20 min. The magnetron‐sputtered film possesses excellent photothermal properties, can produce reactive oxygen species (ROS) with...
CsPbBr3/Cs4PbBr6 nanocomposites recently were found to yield efficient luminescence. However, the formation mechanism of is unclear, and large-scale green synthesis still challenging. Here, we develop a self-assembly reaction fabricate efficiently environmentally friendly. The transmission electron microscopy clearly shows CsPbBr3 nanocrystal embedded in Cs4PbBr6 matrix, forming composite structure. In situ characterization reveals that are formed by two-step reaction, driven ion...
The band-edge emission of CsPb<sub>2</sub>Br<sub>5</sub> was located at 385 nm, not in the visible range as reported literature.
This article discussed a novel hydrogel, which was created through Michael addition. Twom precursors Dextran functionalized Maleimide groups (Dex-Mal) and Hyaluronic Acid thiol (HA-SH) were designed, prepared, characterized by Nuclear Magnetic Resonance (NMR). The formed hydrogels investigated gelation time, swelling studies, viscoelastic properties, degradation rate. Based on time observation, we detected that the hydrogel could be varied with diffident weight percentage of precursors....

Yttrium iron garnet (Y3Fe5O12, YIG) plays a significant role in the field of spintronics due to its low magnetic damping and insulating characteristics. However, most studies have focused on YIG bulk form or as film grown rigid substrates. In this study, has been exfoliated from two-layer-graphene covered (111) Gd3Ga5O12 (GGG) substrate. Magnetic properties under stress are investigated detail via angular dependent ferromagnetic resonance. The relationship between parameters...
Ferromagnetic insulating garnet films with perpendicular magnetic anisotropy (PMA) are of great importance for the applications in spintronics.

Particular emphasis core-shell particles coaxial fibers, thin film heterostructures, planar...
The energy loss of all‐inorganic metal halide perovskite solar cells is large, which reduces the open‐circuit voltage and photoelectron conversion efficiency device. Herein, it found that cathode electron transfer speed much lower than anode hole in CsPbI 2 Br cell with fluorine‐doped tin oxide (FTO) glass/SnO /CsPbI Br/carbon structure, induces charge accumulation at device accordingly. By introducing a new conductive polymer additive polyaniline (PANI) to film, enhanced, resulting balanced...
Abstract Although epitaxial strain imparted by lattice mismatch between a film and the underlying substrate has led to distinct structures emergent functionalities, discrete parameters of limited substrates, combined with relaxations driven thickness, result in severe obstructions subtly regulate electro‐elastic coupling properties perovskite ferroelectric films.
