CoCrFeMnNiNbx (x = 0, 0.25, 0.5, 0.75, and 1.0) high-entropy alloy coatings were prepared on the AISI 1045 steel substrate surface by laser cladding to explore effects of different Nb content microstructure, microhardness, wear resistance, corrosion resistance high entropy coatings. The microstructure CoCrFeMnNi was composed single face-centered cubic (FCC) solid-solution phases without addition. coating mainly a dual-phase structure FCC Laves after addition transformed from hypoeutectic...
Lithiation of individual multiwalled carbon nanotubes (MWCNTs) was conducted in situ inside a transmission electron microscope. Upon lithiation, the intertube spacing increased from 3.4 to 3.6 Å, corresponding about 5.9% radial and circumferential expansions ∼50 GPa tensile hoop stress on outermost tube wall. The straight walls became distorted after lithiation. In compression tension tests show that lithiated MWCNTs were brittle with sharp fracture edges. Such failure mode is stark contrast...
Flexible photodetectors (PDs) have become the latest research interest owing to their potential applications in future implantable sensors and foldable/wearable optoelectronics. Ga2O3, an emerging ultrawide band gap semiconductor, is considered as native photosensitive material for solar-blind PDs. The reported fabrication temperature of Ga2O3 films usually above 600 °C, which hinders its practical application flexible devices. In this work, PDs based on graphene/amorphous van der Waals...
Ga2O3 with a suitable bandgap width is emerging to be novel candidate for future optoelectronic applications in the solar-blind region (<280 nm). Herein, photodetectors are developed by combining layered GaSe flakes epitaxial films, forming van der Waals pn heterojunction. Photoresponse characterizations indicate that GaSe/Ga2O3 junction highly sensitive ultraviolet light, maximum sensitivity at ∼255 nm. The photodetector demonstrates particularly high responsivity of 51.9 A/W, pronounced...
A series of novel carboxyl-functionalized poly(arylene ether nitrile)s (CPAENs) were synthesized via nucleophilic substitution polycondensation reactions 2,6-dichlorobenzonitrile with phenolphthalin and diphenol compounds, using N-methyl-2-pyrrolidone (NMP) as solvent in the presence anhydrous potassium carbonate. The resulting CPAENs exhibited high glass transition temperatures ranging from 181 °C to 251 °C, thermally stable up 400 under either nitrogen or air atmospheres. incorporation...
Abstract Narrowband photodetector (NB‐PD) with selective light detection is critical for artificial vision and imaging. Intrinsic (optical‐filter‐free) NB‐PDs using conjugated organics or halide perovskite materials have been developed eliminating the current complex filtering systems in NB‐PDs. However, poor performance external driving circuit of organic as well doping uncontrollable recombination reactions typical limited their applicational diversification. A p‐type self‐doped intrinsic...

ABSTRACT Although ViT has achieved significant success in the field of image classification, research on ViT‐based object detection algorithms is still its early stages, and their application real‐world scenarios limited. Furthermore, based or Transformer are prone to overfitting issues when training data scarce. While CO‐DETR state‐of‐the‐art precision COCO dataset leaderboard, also suffers from problems, which affect smaller datasets. Based study algorithms, a new algorithm termed DC‐DETR...
