Due to their low toxicity and high-temperature stability, lead-free quasi-2D metal halide perovskites (MHPs) are promising materials for optoelectronic applications. However, understanding their structural and optoelectronic properties, especially excitonic effects (electron-hole pair, -), is challenging due to their quantum well topology. We propose an efficient protocol for band gap correction of

The effect of Al and Zr content on corrosion of AlNiCoCuZr high-entropy alloys in a 5 wt% NaCl solution J. Alloys Compd. (IF 5.8) Pub Date : 2024-09-11 E.A. Karfidov, E.V. Nikitina, B.A. Rusanov
High-entropy alloys are attractive structural materials for the design of apparatus for various chemical technologies due to their relative ease of production, corrosion resistance and high values of mechanical properties (hardness, strength). In the present work, the influence of aluminum and zirconium content on the corrosion resistance of Al-Ni-Co-Cu-Zr high-entropy alloys was studied experimentally

Facile synthesis of MOF-derived carbon-supported LaZn@C nanocomposite as an efficient electrode material for supercapacitor J. Alloys Compd. (IF 5.8) Pub Date : 2024-09-11 Muhammad Younis Qasim, Tauseef Munawar, Mohammed Mujahid Alam, Chang-Feng Yan, Abdullah G. Al-Sehemi, Faisal Mukhtar, Abdul Waheed Rabbani, Usman Ali Akbar, Abbas Saeed Hakeem, Faisal Iqbal
MOF-derived transition metal alloys have attracted researcher's interest in energy storage devices due to their vast surface area, high porosity, adjustable pore sizes, ease of modification, abundant active sites, and 3D tunable structure. Metal alloys covered with carbon can stabilize conductivity and ease charge accumulation, and they are suitable candidates for electrode materials for supercapacitor
