Abstract High entropy alloys (HEAs) composed of multi‐metal elements in a single crystal structure are attractive for electrocatalysis. However, identifying the complementary functions each element HEAs is prerequisite. Thus, V x CuCoNiFeMn ( = 0, 0.5, and 1.0) investigated to identify active role vanadium improving electrocatalytic activity hydrogen evolution reaction (HER). Structural studies show successful incorporation HEA. 1.0 (V ‐HEA) shows an overpotential 250 mV versus reversible...
High entropy alloys (HEA), multicomponent (5 or more) with an equiatomic a near-equiatomic composition, provide unique platform which to engineer surface composition and active sites for developing of efficient electrocatalysts.
This study examines the influence of ZrO2 on austenitic stainless steel 316 (ASS 316). Following addition varying weight percentages (0, 1, 2, and 3) to ASS powder, samples were ball-milled for a duration 30 h then subjected vacuum hot-pressing (VHP) consolidation. After milling, 2 3 wt.% alloys showed diffraction patterns Zr phases other than face-centered cubic phase. Nanocrystalline interacted with 316, which resulted in formation Based findings obtained from X-ray (XRD), phase d-spacing...
High efficiency and mass-scale production ultraviolet (UV) light sources have become a basic requirement for various applications, as such attracted considerable technological interest.
Optical and field emission (FE) properties of aligned single-crystalline ZnO nanorods, grown on aluminium substrate at 530 °C by the non-catalytic thermal evaporation process, have been examined. Raman-scattering room-temperature PL spectra exhibit a strong sharp optical phonon E2 mode 437 cm−1 ultraviolet 381 nm, respectively. The FE characterization shows that turn-on for vertically nanorods was 5.8 V µm−1 current density reached to 0.061 mA cm−2 an applied electrical 9.0 no saturation....
