Quantum Transport in SnTe Nanowire Devices
A variety of quantum transport experiments are observed in SnTe nanowire devices and attributed to microscopic differences in the fabrication. Three categories can be distinguished: semiconducting behavior, partial superconductivity and Fabry‐Pérot oscillations.

Weak separation limit of a two-component Bose-Einstein condensate
This paper studies of the behaviour of the wave functions of a two-component Bose-Einstein condensate in the case of weak segregation. This amounts to the study of the asymptotic behaviour of a heteroclinic connection in a conservative Hamiltonian ...

The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.

The molecular structure of olefin polymerization activator methylaluminoxane (MAO) was probed using ultrahigh field solid‐state NMR backed with DFT calculations, revealing its key motifs and reactive centers. Abstract The structure and reactivity of methylaluminoxane (MAO), a reagent of major interest for olefin polymerization, both industrially and ...

A Ru8%‐Co3O4 catalyst containing Ru single atoms (SAs) exhibits exceptional oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performance in acidic, neutral, and alkaline media. When used as the anode and cathode catalysts in an anion exchange membrane water electrolyzer (AEMWE) device, a low cell voltage of just 2.06 V is needed to

Infinitely many solutions for Hamiltonian system with critical growth
In this article, we consider the following elliptic system of Hamiltonian-type on a bounded domain:−Δu=K1(∣y∣)∣v∣p−1v,inB1(0),−Δv=K2(∣y∣)∣u∣q−1u,inB1(0),u=v=0on∂B1(0),\left\{\begin{array}{ll}-\Delta u={K}_{1}\left(| y| ){| v| }^{p-1}v,\hspace{1.0em ...

An aqueous potassium‐ion battery using vanadium hexacyanoferrate (VHCF) as the cathode and graphite as the anode is presented. During charge/discharge, K+ ions shuttle between electrodes through the electrolyte, enabling energy storage. The VHCF material demonstrates high capacity (≈121 mAh g−1), fast kinetics, and eco‐friendliness, making it a ...
