Superconductivity-Electron Count Relationship in Heusler Phases-the Case of LiPdSi.

We report superconductivity in the full Heusler compound LiPdSi (space group , No. 225) at a critical temperature of = 1.3 K and a normalized heat capacity jump at , Δ/γ = 1.

Enhanced Electrochemical Performance of MnCoFeOSpinel for Oxygen Evolution Reaction through Heat Treatment.

MnCoFeO spinel oxide was synthesized using the sol-gel technique, followed by heat treatment at various temperatures (400, 600, 800, and 1000 °C). The prepared materials were examined as anode electrocatalysts for water-splitting systems in alkaline environments. Solid-state characterization methods, such as powder X-ray diffraction and X-ray absorption spectroscopy (XAS), were used to analyze the materials' crystallographic structure and surface characteristics.

Superconductivity in a breathing kagome metals ROs (R = Sc, Y, Lu).

We have successfully synthesized three osmium-based hexagonal Laves compounds ROs (R = Sc, Y, Lu), and discussed their physical properties. LeBail refinement of pXRD data confirms that all compounds crystallize in the hexagonal centrosymmetric MgZn-type structure (P6/mmc, No. 194).

The valance state of vanadium-key factor in the flexibility of potassium vanadates structure as cathode materials in Li-ion batteries.

Potassium hexavanadate (KVO·nHO) nanobelts have been synthesized by the LPE-IonEx method, which is dedicated to synthesis of transition metal oxide bronzes with controlled morphology and structure. The electrochemical performance of KVO·nHO as a cathode material for lithium-ion batteries has been evaluated. The KVO nanobelts demonstrated a high discharge capacity of 260 mAh g, and long-term cyclic stability up to 100 cycles at 1 A g.

Deciphering the Molecular Mechanism of Substrate-Induced Assembly of Gold Nanocube Arrays toward an Accelerated Electrocatalytic Effect Employing Heterogeneous Diffusion Field Confinement.

The complex electrocatalytic performance of gold nanocubes (AuNCs) is the focus of this work. The faceted shapes of AuNCs and the individual assembly processes at the electrode surfaces define the heterogeneous conditions for the purpose of electrocatalytic processes. Topographic and electron imaging demonstrated slightly rounded AuNC (average of 38 nm) assemblies with sizes of ≤1 μm, where the dominating patterns are (111) and (200) crystallographic planes.
