Abstract Nanoscale metallic glasses offer opportunities for investigating fundamental properties of amorphous solids and technological applications in biomedicine, microengineering, catalysis. However, their top‐down fabrication is limited by bulk counterpart availability, bottom‐up synthesis remains underexplored due to strict formation conditions. Here, a kinetically controlled flash carbothermic reaction developed, featuring ultrafast heating (>10 5 K s −1 ) cooling rates 4 ),...
Abstract The advanced patterning process is the basis of integration technology to realize development next-generation high-speed, low-power consumption devices. Recently, area-selective atomic layer deposition (AS-ALD), which allows direct target materials on desired area using a barrier, has emerged as an alternative process. However, AS-ALD remains challenging use for improvement resolution and selectivity. In this study, we report superlattice-based (SAS-ALD) two-dimensional (2D) MoS 2...
Two-dimensional (2D) inorganic/organic hybrids provide a versatile platform for diverse applications, including electronic, catalysis, and energy storage devices. The recent surge in 2D covalent organic frameworks (COFs) has introduced an counterpart the development of advanced organic/inorganic with improved electronic coupling, charge separation, carrier mobility. However, existing synthesis methods have primarily focused on few-layered film structures, which limits scalability practical...
Halide perovskite nanocrystals (HPNCs) have emerged as promising materials for various light harvesting applications due to their exceptional optical and electronic properties. However, inherent instability in water biological fluids has limited use photocatalysts the aqueous phase. In this study, we present highly water-stable SiO2-coated HPNCs efficient antimicrobial applications. The double SiO2 layer coating method confers long-term structural stability water, while situ synthesis of...
Although microscopic techniques have been used to characterize transition metal dichalcogenides (TMDs), direct observation of charge carrier dynamics distribution in TMDs with diverse shapes remains unexplored. Herein, ultrafast pump–probe microscopy (UPPM) is employed reveal the molybdenum disulfide (MoS 2 ) and tungsten (WS monolayer four shapes: triangular (t‐MoS ), curved (c‐MoS (t‐WS hexagonal (h‐WS ). Monitoring photon transmission T at 1.55 eV after pumping a energy 3.1 eV, negative Δ...

Nanoscale metallic glasses offer opportunities for investigating fundamental properties of amorphous solids and technological applications in biomedicine, microengineering, catalysis. However, the top-down fabrication glass nanostructure is restricted by availability bulk glass; contrast, bottom-up synthesis remains rarely explored due to rigorous formation conditions, especially extreme cooling rate. Here we develop a kinetically controlled flash carbothermic reaction, featuring ultrafast...
