Cu nanoparticles (NPs) were deposited on UV-irradiated TiO(2) in an aqueous solution containing Cu(CH(3)COO)(2) and ethanol by a photocatalytic reaction. Cu NPs on TiO(2) exhibit an extinction (= absorption + scattering + reflection) peak due to localized surface plasmon resonance at around 600 nm initially. The densi…
Abstract. We introduce and discuss discrete two-dimensional models for XY spin systems and screw dislocations in crystals. We prove that, as the lattice spacing ε tends to zero, the relevant energies in these models behave like a free energy in the complex Ginzburg-Landau theory of superconductivity, justifying in a r…
In this work, we demonstrate a new route to generate silica-based multifunctional complex nanorattles. By using SnO2 hollow nanospheres as the starting template, we are able to build a new type of rattle-in-ball hollow structure with multi-level interior architecture, where the core of a nanorattle is itself another s…
The aim of this study is to describe the adhesive capability of Lactobacillus fermenti 126 and Lactobacillus rhamnosus CCM 1825 as well as to isolate and evaluate the functional properties of their synthesized biosurfactants. Fourier transform infrared spectroscopy shows that both crude biosurfactants contain three co…
The extracellular synthesis of silver nanoparticles by Rhizopus stolonifer and its efficacy against multidrug resistant (MDR) strains isolated from burnt cases from hospitals at Gulbarga region, Karnataka, India is reported here. Synthesis of silver nanoparticles was carried out using fungal filtrate and an aqueous so…
In the present work, anodization of zinc foil was investigated in a mixed electrolyte of ammonium sulfate and sodium hydroxide under the influence of different anodization times and concentrations of the electrolyte while the temperature and voltage were kept constant. The ZnO nanoflake arrays formed on Zn foil were c…
Metal incorporation is one of the most effective methods for relaxing internal stress in diamond-like carbon (DLC) films. It was reported that the chemical state of the incorporated metal atoms has a significant influence on the film internal stress. The doped atoms embedding in the DLC matrix without bonding with C a…
In the emerging issue of increased multi-resistant properties in foodborne pathogens, silver nano particles are being used increasingly as antimicrobial agents. Thus, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of Nano Colloidal Silver towards food-borne pathogens such as Es…
A series of dinuclear, trinuclear and tetranuclear lanthanide complexes, formulated as [Nd2(Acc)6(H2O)4]3 [Nd2(Acc)6(H2O)6]·Cl24·8H2O (1), [Dy2(Acc)4(H2O)8]·Cl6·5.89H2O (2), [Ln3(Acc)10(H2O)6]·(ClO4)9·4H2O (Ln = La, (3); Nd, (4)) and [Ln4(μ3-OH)4(Acc)6(H2O)7(ClO4)] ·(ClO4)7·11H2O (Ln = Dy, (5); Yb, (6)), have been syn…
An efficient protocol for selective and sensitive detection of generated hydroxyl radicals was first developed in the photocatalytic system through an electrochemical impedance method and further successfully applied to monitor hydroxyl radicals in the LPS-mediated cellular ROS/RNS burst process.
This project involved the conversion of a British Waterways maintenance craft to a canal boat, powered by a combination of a solid-state hydrogen store, Proton Exchange Membrane (PEM) fuel cell, lead-acid battery pack and a high-efficiency, permanent magnet (NdFeB) electric motor. These replaced the conventional diese…
The development of visible-wavelength photodetectors based on eco-friendly and bandgap engineerable nanomaterials represents an important and promising direction in photodetector study. This highlight reviewed the recent progress in the design and construction of photodetectors based on the environmentally friendly bi…
A novel method for the preparation of highly conductive silver-plated aluminum (Al) microspheres was demonstrated. The surface of the aluminum microspheres was functionalized by a bioinspired polydopamine (PDA) coating. Electroless plating of silver was then carried out on the functionalized aluminum microspheres. An…
Actinyl and actinyl-transition metal complexation by a polypyrrolic macrocycle with anthracenyl linkers between the N(4)-donor compartments was evaluated using relativistic density functional theory which predicts that a highly unusual cofacial bis-actinyl structure complex is stable.
A rare organosulfur one-dimensional coordination polymer, [Co(C(9)H(6)NS)(2)], was synthesized by the reaction between the 8-mercaptoquinoline and cobalt acetate salts in EtOH, which shows strong magnetic coupling and the presence of spin-glassy and spin-crossover phenomena with simultaneous semiconductor behaviour.
Developing of alternative chiral thiol stabilizers from the assembly of achiral thiol (e.g. thioglycolic acid) and chiral ligand (e.g. arginine) via both hydrogen bonding and electrostatic interactions was proposed and successfully applied to an efficient preparation of chiral CdS quantum dots (QDs). Chiral CdS QDs ca…
Many research efforts have focused on the synthesis of organic and inorganic hybrid ordered mesoporous silicas (MSs) with functionalization of the exterior and/or interior surfaces aiming for applications in separation, adsorption, catalysis, drug delivery, and nanotechnology. Among the organic groups, the carboxylic…
Regioregular poly(3-hexylthiophene) (P3HT) was employed as a hole transport material and assistant light absorber for the fabrication of a CdS quantum dot-sensitized solid-state solar cell, by which a power-conversion efficiency of 1.42% was achieved under an AM1.5 G (100 mW cm(-2)) condition.
The synthesis and spectroscopic investigation of Pr(3+):YF(3) nanoparticles with nominal concentration between 0.05% and 5 at% Pr(3+) are reported. Pr(3+) emission in the visible range of the spectrum is investigated at room temperature and at 10 K as well as time resolved spectroscopy as a function of Pr(3+) concentr…
Highly efficient photoswitching tetranuclear rhenium(I) tricarbonyl diimine complexes with a stilbene-like bridging ligand are reported. The ability to directly populate excited states localized on the bridging ligand is the key for the observed efficient photoisomerization.
