Four metal–organic complexes constructed from different polyoxoanions and a tetrazole- and pyridyl-containing asymmetric amide ligand or its <italic>in situ</italic> transformed ligand have been synthesized and structurally characterized.
The synthesized mono Ni( <sc>ii</sc> )-substituted phosphotungstate supported on zirconia was used as a catalyst for the one pot oxidative esterification of benzaldehyde.
Microcracks are purposely introduced in an anodic NiO nanosponge, leading to a mechanically robust electrode with excellent performance for supercapacitor applications.
Nanocomposites of biodegradable PLLA and magnesium oxide composite (PLLA/MgO-NPs) and surface modified magnesium oxide composite (PLLA/m-MgO-NPs) were prepared using a solution casting method.
We report that chronic addition of a low-concentration of nano-TiO <sub>2</sub> to model streams reduced biofilm-associated microbial abundance and activity.
We present a simple method for rendering non-porous materials porous by solution co-processing with organic cage molecules. This method can be used both for small functional molecules and for polymers, thus creating porous composites by molecular blending, rather than the more traditional approach of supporting functi…
Semiconductor based solar cell or photovoltaic cell can be defined as a device that used to convert solar radiation into electrical energy directly. In this study, BST (Barium Strontium Titanate) semiconductor has been manufactured by sol-gel method and with spin coating process. Various mole fractions (x) of 0.5, 0.6…
The effects of scratch, surface element composition, and relative humidity on the hydrogen permeation behavior of zinc coated steels during wet and dry cycle corrosion tests were investigated. The permeating hydrogen was measured electrochemically, and a size controlled scratch was formed on zinc coated steels with a…
Solvent-free electrospinning UV curable materials into ultrathin fibers under UV light radiation and in atmosphere of N <sub>2</sub> or air.
Water oxidation by photosystem II (PSII) converts light energy into chemical energy with the concomitant production of molecular oxygen, both of which are indispensable for sustaining life on Earth. This reaction is catalyzed by an oxygen-evolving complex (OEC) embedded in the huge PSII complex, and its mechanism rema…
Two series of polyimides derived from two asymmetric diamines are synthesised by different polymerization methods. The effect of asymmetry and non-coplanarity of two bisimides on the polymer properties is well investigated.
A nickel oxide doped polyaniline nanofibers (PANI-NiO) based electrochemical sensor was constructed for detection of phenanthrene. Successful synthesis of PANI-NiO nanocomposite was confirmed with techniques such as SEM, XRD, EDX, FTIR, and UV-visible spectroscopy. The electrocatalytic oxidation of phenanthrene on PAN…
, as well as the ability to promote human bone marrow derived mesenchymal stem cell (hMSC) differentiation were demonstrated for both variants of the fusion proteins.
A route for the compatibilization of aqueous dispersions of cellulose nanofibrils (CNFs) with a non-polar polymer matrix is proposed to overcome a major challenge in CNF-based material synthesis. Non-ionic surfactants were used in CNF aqueous dispersions equilibrated with an organic phase (for demonstration, a polysty…
A rare class of dinuclear double-stranded helicates having tetrahedral metal centres with formulae [Co2(L(1))2]·2(CH3CN) (1), [Co2(L(2))2]·6(CH3CN) (2), [Zn2(L(1))2]·2(CH3CN)·(CH3OH) (3) and [Zn2(L(2))2]·4(CH3CN) (4) were synthesized and characterized. Detailed dc and ac magnetic susceptibility measurements reveal the…
The cationic magnesium moiety of magnesium organohaloaluminate complexes, relevant to rechargeable Mg battery electrolytes, typically takes the thermodynamically favourable dinuclear [Mg2Cl3](+) form in the solid-state. We now report that judicious choice of Lewis donor allows the deliberate synthesis and isolation of…
Mesoporous and hollow zinc oxide (ZnO) hierarchical superstructures assembled with compact 1D building blocks that provide an efficient and faster transport pathway for photo-generated charge carriers have been synthesized using a biomass derived polysaccharide "alginic acid". To understand the interactions between th…
Yttrium aluminum borate (YAB) doped with rare-earth ions are promising materials for infrared lasers and self-frequency summing laser systems.
Eco-friendly soy polyester urethane nanocomposite coating materials were prepared by dispersing TiO <sub>2</sub> and Ce-TiO <sub>2</sub> nanoparticles in a 3-isocyanatopropyltriethoxysilane (IPTES) modified soy oil (SO) polyester urethane (PEUTES) matrix.
The synthesis and the ring-opening metathesis polymerization of well-defined poly(ε-caprolactone)-based (oxa)norbornene macromonomers bearing two poly(ε-caprolactone) chains on the polymerizable entity are reported.
