Abstract Next-generation polarized mid-infrared imaging systems generally requires miniaturization, integration, flexibility, good workability at room temperature and in severe environments, etc. Emerging two-dimensional materials provide another route to meet these demands, due the ease of integrating on complex structures, their native in-plane anisotropy crystal structure for high polarization photosensitivity, strong quantum confinement excellent photodetecting performances temperature....
Nanoalloys, especially high-entropy nanoalloys (HENAs) that contain equal stoichiometric metallic elements in each nanoparticle, are widely used vast applications. Currently, the synthesis of HENAs is challenged by slow reaction kinetics leads to phase segregation, sophisticated pretreatment precursors, and inert conditions preclude scalable fabrication HENAs. Here, we report direct conversion metal salts ultrafine on carbonaceous support nanosecond pulsed laser under atmospheric conditions....
Abstract The remarkable capabilities of 2D plasmonic surfaces in controlling optical waves have garnered significant attention. However, the challenge large-scale manufacturing uniform, well-aligned, and tunable has hindered their industrialization. To address this, we present a groundbreaking platform design achieved through magnetic field (MF) assisted ultrafast laser direct deposition air. Through precise control metal nanoparticles (NPs), with cobalt (Co) serving as model material,...
Spatial manipulation of nanoparticles (NPs) in a controlled manner is critical for the fabrication 3D hybrid materials with unique functions. However, traditional methods such as electron-beam lithography and stereolithography are usually costly time-consuming, precluding their production on large scale.

Abstract Metal‐organic framework (MOF) crystals are useful in a vast area of applications because their unique chemical and physical properties. Manufacturing an integrated MOF membrane with 3D nanoarchitectures on the surface is especially important for applications. However, as usually exist powdery crystals, fabrication large area, monolithic, high‐resolution patterns challenging. Here, it found that isolated nanocrystals could be directly converted to monolithic film designed...
Abstract Modulating the heating and cooling during plastic deformation has been critical to control microstructure phase change in metals. During laser shock peening under optimal elevated temperatures, high-density dislocations nanoprecipitates can be generated greatly enhance material strength fatigue life Currently, is limited steady-state heat transfer, such as hot plate, irradiative heating, or far-infrared which slow for practical treatment does not provide transient conditions...
A novel method based on nano-scale precipitation hardening has been studied to strengthen copper-bearing ferrite antibacterial stainless steel. Bimodal precipitations can be observed after annealing and low temperature aging treatment, which are large rod-shaped precipitates nano-sized spherical precipitates, respectively. Due two different morphological the strength of material is significantly improved without sacrificing formability, at same time, excellent properties remain. Under there...
Green production of functional nano-oxides on a large scale is crucial for the modern manufacturing industries. Traditional hydrothermal methods and ball milling are usually time-consuming require long-term energy input with undesired by-products.
