Mononuclear chelates of Cr(III), Mn(II), Fe(III), Ni(II), Cu(II), Zn(II) and Cd(II) resulted from new tridentate Schiff base ligand, 4-((1-(5-acetyl-2,4-dihydroxyphenyl)ethylidene)amino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one, were synthesized. Metal to ligand ratio was found to be1:1, which was revealed via elemental analysis and characterized via various spectroscopic tools. IR has point out

Hansgeorg Schnöckel, Professor emeritus at the Institute for Inorganic Chemistry at the Karlsruhe Institute of Technology (KIT), celebrated his 80th birthday in May 2021. Friends and colleagues as well as the publisher and editors of Zeitschrift für Anorganische und Allgemeine Chemie (ZAAC) congratulate him cordially on this special occasion and dedicate this issue of ZAAC to him in recognition of

Calcium silicates are the main components in cement clinkers. Alite, the nesosilicate or island silicate Ca3SiO5 , also named C3S in cement chemistry notation, represents the main phase in Portland cement clinkers. Due to the metastability of Alite at room temperature, quenching from high temperatures is mandatory for phase preservation and impurities are important structure directing factors. Those

To unambiguously clarify the long-debated crystal structure of the low-temperature orthoborate π ‑YBO 3 , single-crystals of the europium-doped π ‑YBO 3 :Eu 3+ were prepared via a high-pressure/high-temperature route at 7.5 GPa and 1400 °C. The structure was solved and refined in the monoclinic space group C 2/ c (no. 15) in the pseudowollastonite structure type, with the lattice parameters a = 11

Silicon carbide (SiC) particles are exciting structures because of their hardness, chemical inertness, and dielectric properties. In particular, their absorption/emission properties in the mid-infrared range render them suitable structures for ambient temperature thermal emitters. However, the synthesis of uniform, spherical structures is still challenging. Here, we present a robust synthesis procedure

Amyloid-β (Aβ ) aggregates are one of biomarkers of Alzheimer’s disease (AD) . It is well known that Aβ aggregates display neurotoxicty or cytotoxicity to neurons. Thus, degrading Aβ aggregates is crucial for exploring the treatment of AD. Moreover, the excessive production of HOCl in the AD brain is an important feature of the disease. Herein, a novel compound MB-O based on methylene blue (MB) sk
