Recent advances in hybrid organic-inorganic materials with spatial architecture for state-of-the-art applications

Preparation, spectroscopic study of Schiff base derived from dopamine and metal Ni(II), Pd(II), and Pt(IV) complexes, and activity determination as antioxidants

“…[ 1 ] DA is one of a good number of natural tryptamine derivatives occurring in plants and animals such as serotonin, melatonin, gramine, histamine, octopamine, norepinephrine, and epinephrine. [ 2,3 ] Tryptamine derivatives have significant properties such as neurotransmission, neuromodulation, vasoconstriction, and vasodilation and are antimicrobial, antibacterial, antioxidant, antifungal, anti‐inflammatory, and antidepressant. These are also used for migraine treatment, suppression of nausea and vomiting caused by cancer chemotherapy and radiotherapy, treatment of irritable bowel syndrome, and control of the diurnal rhythm of various physiological functions.…”

New pivot for investigating flame‐retarding mechanism: Quantitative analysis of zinc phosphate doped aliphatic waterborne polyurethane‐based intumescent coatings for flame‐retarding plywood

“…Because the degradation of APP mainly occurs in the range of 300-400 C, the coating simultaneously melts and decomposes releasing NH 3 , H 2 O, and phosphoric acid in this step. 20 Combining with the experimental results, an appropriate ZnP (2 wt%) imparts an enhanced flame resistance to the AWP-based coating, the reasons are briefly analyzed as the following. Firstly, the enhanced "heat sink" leads to the increased TTI (in Table 2) and heatabsorption (in Table 3), which triggered by ZnP delays the water loss during firing effectively, due to the creation of Brønsted acid sites.…”

“…Additively, inorganic fllers, including mineral‐based materials have been recently reported to improve the flame‐retarding performance of polymeric materials 20 . The phosphorus compounds (PO, PO 2 , PO 3 , and PO 4 ) could be converted into phosphoric acid during thermal decomposition, which then condense to polyphosphate and promote charring, and also traps of the reactive H‐ and OH‐radicals 21,22 .…”

Spectroscopic characterization for new complexes with 2,2′‐(5,5‐dimethylcyclohexane‐1,3‐diylidene)bis(azan‐1‐yl‐1‐ylidene)dibenzoic acid

“…The results of calculations show that the LUMO of transition metal ions prefer to react with the HOMO of four-donor atoms of two oxygen of carbonyl and nitrogen of azomethen group for free ligand (H 2 L). [30][31][32][33]…”
