EVALUATION OF ANTIBACTERIAL ACTIVITY OF ZnO NANOPARTICLES COATED SONOCHEMICALLY ONTO TEXTILE FABRICS Gagandeep Singh, Eadaoin M. Joyce*, James Beddow and Timothy J. Mason Address*: Dr Eadaoin M. Joyce, The Sonochemistry Centre, Coventry University, Faculty of Health and Life Sciences, Priory Street, Coventry, CV1 5FB,…
Due to the emergence of smart textiles and wearable textile systems, the need for electrically conductive textiles has become increasingly clear. Often this conductivity is achieved by integrating metal particles, fibres or yarns into textiles or by coating a textile with a metallic layer. In this research, the potent…
Photosynthetic diatom plastids have long been suggested to have originated by the secondary endosymbiosis of a red alga. However, recent phylogenomic studies report a high number of diatom nuclear genes phylogenetically related to green algal and green plant genes. These were interpreted as endosymbiotic gene transfer…
The electronic structure and the chemical bond in titanium dichalcogenides TiX2 (X = S, Se, Te), which are promising electrode materials for lithium batteries, are studied experimentally and theoretically. It is found that the X-ray photoelectron spectra of the valence bands and the core levels of titanium and its X-r…
A titanium dioxide (TiO2) surface coating was applied to improve both the electrochemical and thermal properties of SiO as a high energy density anode for Li-ion batteries. A nano-scale, thin anatase TiO2 coating was achieved using a facile sol–gel process, and coated and non-coated SiO were characterized using variou…
Although Al has a lower redox potential [Al3+/Al, −1.67 V vs. SHE] than most metallic ions, metal galvanic replacement reactions on pure aluminum foil can be hardly observed because of the existence of the thin layer of aluminum oxide, In this work, we develop a facile, economical and general approach to achieve large…
A highly durable SiOC composite anode was prepared for use in lithium secondary batteries. The SiOC composite was synthesized by electrodeposition of SiCl4. The composite anode delivered a discharge capacity of 1045 mA h per gram of Si at the 2000th cycle and 842 mA h per gram of Si even at the 7200th cycle. The reaso…
New luminescent lanthanide-carboxylate frameworks, formulated as [Ln4(m-BDC)6(H2O)4(DMF)]·(H2O)2·(DMF) (Ln = Eu 1; Gd 2; Tb 3) (m-H2BDC = 1,3-benzenedicarboxylic acid) have been solvo(hydro)thermally synthesized. Single-crystal X-ray diffraction studies reveal that compounds 1–3 are isomorphous and each displays a lay…
Oxygen-deficient TiO(2) nanowires show substantially increased donor density due to an increase in oxygen vacancies introduced intentionally by thermal treatment in ammonia, vacuum, or hydrogen. By coupling oxygen-deficient TiO(2) nanowires with CdS quantum dots, a significant enhancement in their photoactivities was…
Mo-doped BiVO(4) nanocrystals with low bandgap energy were embedded into the surface of WO(3) film, resulting in WO(3)/BiV(0.95)Mo(0.05)O(4) photoanodes, which were tested in photoelectrochemical cells for water splitting. Bilayer photoelectrochemical cells showed enhanced photocurrent density: three times that shown…
One-dimensional (1-D) TiO(2) nanorod arrays (NRAs) with large inner surface area are desired in dye-sensitized solar cells (DSSCs). So far, good performance of DSSCs based on 1-D rutile TiO(2) NRAs remains a challenge mainly owing to their low dye-loading ability resulting from the insufficient specific surface area o…
Heterogeneous photocatalysis continues to be an active area of research with focus on developing catalytic systems that can degrade toxic pollutants in the gas and aqueous phase, and split water to generate hydrogen and oxygen. In this review, the incorporation of silica phases in titanium dioxide based photocatalysts…
Coordination of a tetratopic nitrogen-rich linker with Zn(2+) under solvothermal conditions afforded a Zn-based metal organic framework (MOF), where the Zn(II) ions could be exchanged by Cu(II) ions in a single-crystal-to-single-crystal fashion leading to a new Cu-based MOF. Such transformation induces a significant e…
We demonstrate a simple hydrothermal method based on an oxidation–reduction reaction between graphene oxide (GO) and SnCl2·2H2O, to produce SnS2@graphene nanosheet composites. These hybridizations reveal enhanced lithium storage properties with high reversible capacities and excellent cycling stability.
A series of benzoheteroarene-fused boroles, containing pyrrole, furan, and thiophene as the heteroarene rings, were synthesized and their structures were determined by X-ray crystallographic analysis. Their antiaromaticity was assessed by calculations of the nucleus-independent chemical shift (NICS) values using the g…
NiO p-type semiconducting nanowires with high aspect ratios up to approximately 2000 have been prepared by chemical reduction under assistance of magnetic fields and subsequent heat treatment method. The diameter of NiO nanowires is about 150 nm and the length can be up to 300 μm. Ni nanowires have been prepared from…
The possibility of hydrogen production by photo-catalytic decomposition of water on titania has provided the incentive for intense research. Titania is the preferred semiconductor for this process, in spite of its large band gap (~3.2 eV) that restricts its utility only in the UV region. Various sensitization methodol…
We report a simple, effective approach to modifying two kinds of D–A type polymers; copolymerization with thiophene containing tris(thienylenevinylene) (TTV) conjugated side chain. The resulting copolymers, TTV1 and TTV2, showed significant improvement (25% and 43%) of power conversion efficiency in comparison to the…
The rate of hydrogen production from vapour-phase formic acid decomposition can be increased by 1-2 orders of magnitude by doping a Pd/C catalyst with potassium ions. Surface potassium formate and/or bicarbonate species could be involved in the rate-determining step of this reaction.
The series of anhydrous lanthanide chlorides LnCl3, Ln = Pr–Tb, and 4,4′-bipyridine (bipy) constitute isotypic MOFs of the formula 2∞[Ln2Cl6(bipy)3]·2bipy. The europium and terbium containing compounds both exhibit luminescence of the referring trivalent lanthanide ions, giving a red luminescence for Eu3+ and a green…
