Computational Modeling and Experimental Validation of Variabilities in Chemical Vapor Deposition of Graphene on Metals

Small, EarlyView.
ABSTRACT Achieving laterally uniform graphene coatings via low‐pressure chemical vapor deposition (LPCVD) remains challenging due to substrate‐scale variations in near‐wall transport that govern precursor renewal and local growth. Here, transient 3D CFD is coupled with spatially resolved characterization to examine how substrate inclination reorganizes

Single Cu Atom Sites on Co3O4 Activate Interfacial Oxygen for Enhanced Reactivity and Selective Gas Sensing at Low Temperature

Small, EarlyView.
Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...

Super‐High Sodium‐Ion Conductivity of Na2.9Sb0.9W0.1S4 at Low Pressures by Systematic Pressure and Temperature Treatments

Small, EarlyView.
Systematic pressure and temperature treatment of the sodium ion electrolyte Na2.9Sb0.9W0.1S4 enabled deep insight into the effects of these parameters on the sodium conductivities and their impedance‐spectroscopic measurements, and afforded a material exhibiting a record superionic conductivity of 44.7 mS cm−1 at pressures down to 18 MPa and an ...

Ferromagnetic Cobalt Oxide With Structural Distortion and Oxidation State Changes for Hydrogen Sulfide Gas Detection

Small, EarlyView.
High H2S gas sensitivity was improved by electrochemically engineering Co3O4/CoO heterostructures with oxygen vacancies and aligning nanosized particles via magnetic‐field‐assisted deposition. This alignment enhanced gas diffusion and electron transport, reducing base resistance. The resulting sensor exhibited high selectivity and a strong response (Rg/

Tailoring the Melting and Glass Transition Behavior of Zeolitic Imidazolate Frameworks via Ammonium Halide Salts

Small, EarlyView.
Ammonium halide salts serve as inorganic modifiers that lower the melting and glass transition temperatures of zeolitic imidazolate frameworks, enabling centimeter‐scale hybrid glasses and melt processing of otherwise unmeltable ZIF‐8. In situ imaging and pair distribution function analysis reveal salt infiltration, Zn─N bond disruption, and Zn–halide ...
