Summary: In this work, the performance of c-Si/ZnO heterojunction ultrathin-film solar cells is enhanced by an integrated structure of c-Si trapezoidal pyramids on the top and Al pyramids in the active layer. The top c-Si pyramid increases absorption of short wavelengths and the bottom Al pyramid improves overall optical absorption, resulting in a high absorption rate of 93.16%. The optimized current density and conversion efficiency of the solar cells are 41.94 mA cm(-2) and 18.97%, respectively. The solar cells show good absorption in a wide range of incident angles and the electric field intensity profile demonstrates excellent light-trapping performance.

Summary: A breakthrough in fabricating a long lifetime transmon qubit was reported, using tantalum films as the base superconductor with a dry etching process. The transmon qubits achieved a best T-1 lifetime of 503 μs, outperforming those fabricated with niobium and aluminum. The stable and highly anisotropic dry etching process of tantalum film shows promise for fabricating medium- or large-scale superconducting quantum circuits with longer lifetimes, meeting the requirements for practical quantum computers.

Summary: The chemical ligand BSBAE was embedded indirectly on mesoporous silica to fabricate optical composite materials (OCM) for detecting and removing toxic cadmium (Cd(II)) ions from wastewater solutions. The OCM demonstrated high sensitivity and selectivity towards Cd(II) ions in acidic pH conditions (pH 3.50) and showed distinguishable color changes upon the addition of trace levels of Cd(II) ions. Other metal ions did not significantly affect the performance of the OCM, which had a detection limit of 0.32 μg/L and a maximum adsorption capacity of 179.65 mg/g for Cd(II) ions. Cd(II) ions could be successfully desorbed from the saturated OCM using 0.25 M HCl, and the regenerated OCM maintained its selectivity and adsorption capacity. However, the adsorption efficiency slightly decreased after multiple cycles. Therefore, the OCM offers a cost-effective and viable alternative for detecting and removing toxic Cd(II) ions from wastewater.

Summary: Specific ion effects (SIE) have been studied for over 130 years and are observed in various fields. However, there is currently no general theory to explain ion specificity. This review explores the historical explanations for SIE in water, the properties of key ions, and the behavior of ions at the liquid-vapor interface. It also discusses SIE in mixed electrolytes, nonaqueous solvents, and highly concentrated electrolyte solutions, which are exciting frontiers with relevance to biological and electrochemical applications. The article concludes by summarizing the challenges and opportunities in SIE research and the potential for a general predictive theory.

Summary: The study demonstrates that indium doping can significantly enhance the sensitivity and selectivity of ZnO nanosheets to acetylene gas. The adsorption energy of acetylene increases significantly after indium doping, with the interaction mainly attributed to electrostatic forces. The indium-doped ZnO nanosheets can selectively detect acetylene in the presence of other gases and exhibit a short recovery time.

Summary: This paper proposes an actively tunable and switchable multi-functional terahertz metamaterial device based on a hybrid vanadium dioxide (VO2)-graphene integrated configuration. The functions of the device can be reversibly switched between asymmetric transmission and two different polarization conversions by transiting the phase of VO2. The performance of the device can be actively controlled by adjusting the geometrical parameters and Fermi energy of graphene.
