Manipulating and dispensing liquids on the micrometre- and nanoscale is important in biotechnology and combinatorial chemistry, and also for patterning inorganic, organic and biological inks. Several methods for dispensing liquids exist, but many require complicated electrodes and high-voltage circuits. Here, we show a simple way to draw attolitre liquid droplets from one or multiple sessile dr...

Maleimide-functionalized polystyrene (PSMA-SiO2/TiO2) hybrid nanocomposites were prepared by sol-gel reaction starting from tratraethoxysilane (TEOS) and titanium isopropoxide in the solution of polystyrene maleimide in 1,4-dioxane. The hybrid films were obtained by the hydrolysis and polycondensation of TEOS and titanium isopropoxide in maleimide-functionalized polystyrene solution followed by...

Recently, the Al2O3–TiO2–ZrO2 system has found valuable applications, particularly, as a support for NOx storage–reduction (NSR) catalysts. Nanocomposite powders were prepared from the co-precipitation method in inorganic precursors. The behaviors of mixed oxide nanoparticles under ultrasonic irradiation, such as dispersion, and crushing were studied. Phase transformations, crystallite size, an...

We report molecular dynamics simulations for telechelic molecules composed of two polyhedral oligomeric silsesquioxane (POSS) cages connected by one hydrocarbon backbone dissolved in liquid normal hexane. Silsesquioxanes are novel hybrid organic-inorganic molecules that are useful as building blocks for the synthesis of nanostructured materials. By including POSS molecules within a polymeric ma...

The effects of solution (sol) processed contacts of indium tin oxide (ITO-sol) and gold (Au-sol) on solar cells are tested. When combined with solution processed active layers of CdTe/CdSe, all-inorganic fully solution processed solar cells are produced on non-conductive glass substrates. Under AM 1.5G illumination, open circuit voltages (Voc), short circuit currents (Jsc) and efficiencies (η) ...

The water solution of an intriguing luminescent 'Inorganic Co-crystal' of Cu(II) monomeric and dimeric units shows extremely selective sensing ability towards inorganic arsenic(III) in water medium in the pico-molar concentration range even in the presence of other cations.

There are a large number of assays in cellular and molecular biology that either produce or consume inorganic phosphate. Therefore, the ability to quantitatively measure these phosphorous compounds can allow the assessment of the associated enzymes. Here we describe the use of the mQuant Scanning microplate spectrophotometer to quantitate ATPase activity by measuring inorganic phosphate in solu...

The scarcity of freshwater is one the major challenges to civilized community around World. So, various engineered processes have been developed for remediation this problem such as osmotic pressure-driven (OPDPs). OPDPs includes forward osmosis and pressure retarded osmosis, which gained enormous attention becoming a flexible membrane-based technology desalination wastewater treatment. most si...
