Abstract Molybdenum phosphide (MoP) is a promising non‐noble‐metal electrocatalyst in the hydrogen evolution reaction (HER), but practical implementation impeded by sluggish HER kinetics and poor chemical stability. Herein, novel high‐efficiency comprising MoP nanoflakes intercalated nitrogen‐doped graphene nanobelts (MoP/NG), which are synthesized one‐step thermal phosphiding organic–inorganic hybrid dodecylamine (DDA) inserted MoO 3 nanobelts, reported. The DDA molecules situ carbonized...

The quest for novel nanomaterials with unusual functionalities continues to be a central challenge modern nanoscience. Here we report surprisingly anomalous hardening behavior exhibited by class of transition-metal monoborides (TMB). Most remarkable is the occurrence intrinsic hardness maximum at valence-electron concentration (VEC) about 8 electrons per formula unit (e f.u.); both lower and higher VECs lead decrease hardness, contrasting expected positive correlation between VEC. Such an...

The search for new superhard materials has usually focused on strong covalent solids. It is, however, a huge challenge to design metals because of the low resistance metallic bonds against formation and movement dislocations. Here, we report microscopic mechanism enhancing hardness by identifying highly stable thermodynamic phases strengthening weak slip planes. Using well-known transition-metal borides as prototypes, demonstrate that several possess unexpectedly high whereas exhibit an...

Electrocatalysis is crucial for sustainable energy solutions, focusing on harvesting, storage, and pollution control. Despite the development of various electrocatalysts, understanding dynamic processes in electrochemical reactions still limited, hindering effective catalyst design. In situ Raman spectra have emerged as a critical tool, providing molecular-level insights into surface under operational conditions discussing their development, advantages, configurations. This review emphasizes...

We investigate the performances of near-ultraviolet (about 350 nm–360 nm) light-emitting diodes (LEDs) each with specifically designed irregular sawtooth electron blocking layer (EBL) by using APSYS simulation program. The internal quantum efficiencies (IQEs), light output powers, carrier concentrations in wells, energy-band diagrams, and electrostatic fields are analyzed carefully. results indicate that LEDs composition-graded p-AlxGa1−xN EBLs have better than their counterparts stationary...

Circularly polarized light emission (CPLE) can be potentially applied to three-dimensional displays, information storage, and biometry. However, these applications are practically limited by a low purity of circular polarization, i.e., the small optical dissymmetry factor gCPLE. Herein, glancing angle deposition (GLAD) is performed produce inorganic nanohelices (NHs) generate CPLE with large gCPLE values. CdSe NHs emit red = 0.15 at helical pitch (P) ≈ 570 nm, having 40-fold amplification...
