In this work, the hexagonal variant of the Ce2PdGe3 system is studied, which crystallizes in the AlB2-type structure (space group P6/mmm, hP3) and exhibits cluster spin-glass type behavior. The physical properties are studied by magnetization, heat capacity and electric resistivity, which showed that AlB2-type Ce2PdGe3 (h-Ce2PdGe3) can be classified as a cluster glass material with the freezing temperature Tf = 3.44 K in contrast...

Bisphosphonates (BPs) are an important treatment for osteoporosis and bone metastases due to their low toxicity, high thermostability, and the ability to inhibit bone resorption. Notably, BPs like alendronate, which contain a primary amine group, exhibit potent antiresorptive and antiangiogenic properties. Recent studies have focused on enhancing the BP properties by incorporating bioactive metals to increase their therapeutic...

The synthesis and characterization of a new compound Mg4Pd7As6, which is found to be a superconductor with Tc = 5.45 K is reported. Powder X-ray diffraction confirms the U4Re7Si6 structure (space group Im-3m, no. 229) with the lattice parameter a = 8.2572(1) Å. Magnetization, specific heat, and electrical resistivity measurements indicate that it is a moderate-coupling ( = 0.72) type-II superconductor. The electronic and phonon...

This paper presents theoretical and experimental studies on the superconductivity of Pb0.64Bi0.36 alloy, which is a prototype of strongly coupled superconductors and exhibits one of the strongest coupling under ambient pressure among the materials studied so far. The critical temperature, the specific heat in the superconducting state, and the magnetic critical fields are experimentally determined. Deviations from the single-gap...

Water pollution has become a critical global concern requiring effective monitoring techniques and robust protection strategies. Contaminants of emerging concern (CECs) are increasingly detected in various water sources, with their harmful effects on humans and ecosystems continually evolving. Based on literature reports highlighting the promising sorption properties of metal-organic frameworks (MOFs), the aim of this study was...
