We report the formation and characterisation of easily functionalisable mixed micelles with DNA/PEO corona and PPO core which can be loaded with hydrophobic molecules and stabilised by the formation of a cross-linked semi-interpenetrating network. Furthermore, the corona is functionalised by hybridisation either with dye-modified complementary DNA, with demonstrable distance control, or with DN...

Nanofibers, produced by electrospinning a solution containing titanium tetra(IV) isopropoxide, polyvinyl acetate and acetic acid in N,N-dimethyl acetamide, upon sintering at 500 °C produce rice grain-shaped TiO(2) mesostructures. Each rice grain-shaped TiO(2) has a mixed crystal structure and high porosity and the mesostructures are found to have applications in dye-sensitized solar cells.

A method is presented for estimating the concentration of T-1824 in lipemic plasma. The plasma is mixed with acetone, which precipitates the proteins, dissolves or precipitates the lipids, and yields a clear solution for photometric measurement of the dye. The method is not sensitive to changes in the degree of lipemia and is relatively insensitive to hemolysis.

Metal and metal oxides are widely used in industry, and to optimize their performance their surfaces are commonly functionalized by the formation of thin films. Self-assembled monolayers (SAMs) are deposited on metals or metal oxides either from solution or by gas deposition. The gas deposition enables the preparation of SAMs under very well controlled conditions in ultrahigh vacuum (UHV). Thio...

water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...

Abstract This work presents betanin dye-loaded TiO 2 -ZnO thin film solar cells for energy harvesting. The nanocomposite was prepared by the one-step microwave-assisted technique. Structural studies exhibit mixed phases of rutile and wurtzite structure ZnO respectively. morphological investigations deposited showed interconnected many-fold nanoflakes morphology. EDS confirms formation stoichiom...

objective: in nigeria the rate of contraceptive use among sexually active adolescents is about 30%, considerably lower than the rates reported for developed countries. this study aimed to determine the knowledge, perception and practice of emergency contraception among female adolescent hawkers in rigasa community, a suburb of kaduna town. materials and methods: a cross sectional descriptive st...
