Adding Li to ZnO:Nd3+ based on first-principles calculations reduces the elastic properties such as Young's modulus, bulk modulus, and shear modulus. In the softened LixZn1−xO:Nd3+ system, the introduction of significant strain energy is expected to improve the mechanoluminescence intensity. For further details of this study, see article number 2400099 by Chao-Nan Xu and co-workers.
Rare-earth tritellurides (RTe3) are popular for their charge density wave (CDW) phase, magnetotransport properties, and pressure-induced superconducting state among other features. In this literature, Density functional theory is exploited to study various properties of NdTe3. The calculated elastic and thermomechanical parameters, which are hitherto untouched for any RTe3, uncover soft, ductile, highly machinable, and damage-tolerant characteristics, as well as highly anisotropic mechanical behavior of this layered compound. Its thermomechanical properties make it a prospective thermal barrier coating material. Band structure, density of states, Fermi surfaces, and various optical functions of the material are reported. The band structure demonstrates highly directional metallic nature. The highly dispersive bands indicate very low effective charge carrier mass for the in-plane directions. The Fermi surfaces display symmetric pockets, including signs of nesting, bilayer splitting among others, corroborating previous works. The optical spectra expose high reflectivity across the visible region, while absorption is high in the ultraviolet region. Two plasma frequencies are noticed in the optical loss function. The optical conductivity, reflectivity, and absorption reaffirm its metallic properties. The electronic band structure manifests evidence of CDW phase in the ground state.
The cover image depicts the transfer of biomolecules in double charge-modified nanochannels for efficient targeted sorting of different types of amino acids. This phenomenon is attributed to the generation of opposing electroosmotic fluxes within the different charge-modified nanochannels, which allows amino acids to be efficiently separated and sorted according to their specific charge properties. The central motif symbolizes the periodically switching external electric field. For further information, see article number 2301251 by Wei Si and co-workers.
