“…Further the C‐S bond distances in these complexes was found to be in the range of 1.686‐1.700 Å suggesting that it is intermediate between single C‐S (1.82 Å) and double C=S (1.56 Å) bond distances . The bond lengths in these complexes are normal and consistent with the к 2 ‐N,S‐ coordination of the thiourea derivatives which correlates well with reported values for similar complexes . The metal to nitrogen bond distances is comparatively shorter than the metal to sulfur bond distances (Table ).…”

The d 6 metal complexes of thiourea derivatives were synthesized to investigate its cytotoxicity. Treatment of various N-phenyl-N´pyridyl/pyrimidyl thiourea ligands with half-sandwich d 6 metal precursors yielded a series of cationic complexes. Reactions of ligand (L1-L3) with [(p-cymene)RuCl 2 ] 2 and [Cp*MCl 2 ] 2 (M = Rh/Ir) led to the formation of a series of cationic complexes bearing general formula [(arene)M(L1)к 2 (N,S) Cl] + , [(arene)M(L2)к 2 (N,S) Cl] + and [(arene) M(L3)к 2 (N,S) Cl] + [arene = p-cymene, M = Ru (1, 4, 7); Cp*, M = Rh (2, 5, 8); Cp*, Ir (3, 6, 9)]. These compounds were isolated as their chloride salts. X-ray crystallographic studies of the complexes revealed the coordination of the ligands to the metal in a bidentate chelating N,S-manner. Further the cytotoxicity studies of the thiourea derivatives and its complexes evaluated against HCT-116 (human colorectal cancer), MIA-PaCa-2 (human pancreatic cancer)and ARPE-19 (non-cancer retinal epithelium) cancer cell lines showed that the thiourea ligands displayed no activity. Upon complexation however, the metal compounds possesses cytotoxicity and whilst potency is less than cisplatin, several complexes exhibited greater selectivity for HCT-116 or MIA-PaCa-2 cells compared to ARPE-19 cells than cisplatin in vitro. Rhodium complexes of thiourea derivatives were found to be more potent as compared to ruthenium and iridium complexes.

“…Facile composite membranes consisting of SPEEK/poly (amide imide) (PAI) and SrTiO 3 -based nanocomposite electrolyte were prepared by a solvent-casting technique to exploit the combined network of SPEEK, PAI, and SrTiO 3 , owing to polymer matric of stability criteria on hydrogen bonding and excellent proton conductor, as well as being hydrophilic in nature. This offers enhanced stability and the ability to fine-tune proton conductivity in the existence of PAI and SrTiO 3 [ 68 , 70 ]. Yavari et al synthesized a PtNP–CNTs–NdFeO3NPs–CH nanocomposite in a direct methanol fuel cell (DMFC) with perovskite oxide, which exposed the multifunctional energy harvesting using a single engineered material [ 71 ].…”

Perovskite-based electrode catalysts are the most promising potential candidate that could bring about remarkable scientific advances in widespread renewable energy-storage devices, especially supercapacitors, batteries, fuel cells, solid oxide fuel cells, and solar-cell applications. This review demonstrated that perovskite composites are used as advanced electrode materials for efficient energy-storage-device development with different working principles and various available electrochemical technologies. Research efforts on increasing energy-storage efficiency, a wide range of electro-active constituents, and a longer lifetime of the various perovskite materials are discussed in this review. Furthermore, this review describes the prospects, widespread available materials, properties, synthesis strategies, uses of perovskite-supported materials, and our views on future perspectives of high-performance, next-generation sustainable-energy technology.

“…The best proton mobility was achieved from the composite membranes only by incorporating the barium cerate nanoparticles in the SPEEK-PAI. 14,15 The goal of the investigations is to prepare the SPEEK composite membranes by using the base polymer of PAI with sufficient proportions of hydrophilic BaCeO 3 nanoparticles (2, 4, 6, 8 wt%). The SPEEK/PAI/BaCeO 3 combination has given an enhanced conductivity and stability of the membrane matrix by the hydrogen bond interplay between the SPEEK-PAI and BaCeO 3 .…”

The fluorinated Nafion is replaceable by the non-fluorinated clean sulfonated poly (ether ether ketone) for hydrogen-based fuel cell. The acid-base blending of PAI to clean sulfonated poly ether ether ketone (SPEEK) increased the thermal, mechanical, and oxidative properties and decreased the conductivity. It interpreted that higher stability properties appeared on the blended membrane. The loading of BaCeO 3 nanoparticles in the SPEEK/poly (amide-imide) (PAI) matrices was done via solution casting process. This outcome provides improved conductivity, ion-exchange property, water uptake (WU) with controlled stability due to the good interfacial interplay among nanoparticles and polymer. The high conductivity (14.98 × 10 −3 S cm −1 at 80 C) was reached by SPEEK/PAI /BaCeO 3 (90/10/06 wt%) membrane (B3) measured in the electrochemical four-probe impedance spectroscopy. Its current density and power density values are 269 mA cm −2 and 66 mW cm −2 , respectively. The voltage retention of the B3 membrane was maintained almost at 0.92 V and degradation of voltage after 20 hours in the durability study was about 0.01 V.
