The selective synthesis of pure-phase La2(WO4)3 nanocrystals and uniform spindle-like NaLa(WO4)2 nano/microcrystals with tunable size based on one reaction system has been reported for the first time. The sodium ion is crucial for the selective synthesis of La2(WO4)3 and NaLa(WO4)2. An additional hydrothermal treatmen…
The samples of Cd1 － xCoxS with compositions x = 0.0 & 0.6 were prepared by Co-precipitation route at room temperature. XRD analysis confirms that the samples have cubic structure with no impurity phases. The lattice parameter, volume cell, X-ray density and grain size were calculated using XRD data. It is found that…
The inhibition performance of thiobenzamide (TB) against the under-deposit corrosion of carbon steel in CO 2 -saturated, chloride-containing environment has been investigated. TB concentrations were varied from 10 – 200 ppm and temperatures from 30°C to 60°C were tested. TB effectively inhibits corrosion at carbon ste…
Sulphamic acid (HSO3NH2) is a potential material that exhibits excellent piezoelectric and non-linear optical properties. Nucleation and growth kinetics give valuable information about the crystal growth process, which can be employed in the growth of large size crystals. Thus we have studied its nucleation parameters…
The amount of indium in indium zinc tin oxide (IZTO) was reduced by over 20% by manufacturing an IZTO target containing ZnO for application as the transparent conducting oxide (TCO) anode of polymer light emitting diodes (PLEDs). The IZTO target was manufactured with the composition In2O3 (70 at%)–ZnO (15 at%)–SnO2 (1…
By using L-cysteine-CdTe/ZnS quantum dots (QDs) as pH-dependent fluorescent probes, a facile and sensitive method was proposed for the selective detection of IO4− and Ni2+ ions. L-cysteine-CdTe/ZnS QDs could be used as selective fluorescent probes to determine IO4− and Ni2+ ions at different pH conditions (pH 3.5 or 1…
The supramolecular self-assembly and disassembly that are responsive to external stimuli are of critical importance to the design and synthesis of functional supramolecular materials. In this work, we performed a coarse-grained molecular dynamics study of photo-controlled assembly and disassembly on a timescale of ten…
A Langmuir film of bis(zinc octaethylporphyrin) (ZnPP) was characterised at the air–water interface and its syn–anti conformation switching induced upon addition of aromatic amines was studied by infrared and UV–vis reflection spectroscopic methods. The highly specific interaction of ZnPP with aromatic amines was main…
A green one-pot approach is used to synthesize surface morphology controlled hollow silica spheres in aqueous solution under ambient conditions. Using cationic polystyrene particles as a template and aminopropyltriethoxysilane (APTES) as a structural directing agent, the surface roughness and wall thickness could be e…
We designed poly(aryl ether) dendron based transparent hydrogels containing glucose moiety, which undergoes in situ transition from nanofibers to spherical aggregates, upon pH variation. The process is reversible and the assembled structures have been characterized by DLS and SEM. More importantly, efficient dispersio…
A series of magnetic chitosan/Fe3O4/halloysite nanotubes/ofloxacin (CTS/Fe3O4/HNTs/OFL) microspheres was prepared by spray-drying for the sustained release of OFL. CTS was in situ crosslinked by glutaraldehyde in the spray-drying process. The magnetic microspheres were characterized by FT-IR, scanning electron microsc…
The morphology, composition, and structure of semiconductor nanomaterials play important roles in tuning their unique physical and chemical properties for a variety of applications. We report a facile chemical method to etch cuprous oxide microcrystals which resulted in excellent performance in surface-enhanced Raman…
An Otsuka Long-Evans Tokushima Fatty (OLETF) rat provides a useful model for studies to develop corneal wound healing drugs for use in diabetic keratopathy resulting from type 2 diabetes mellitus. We investigated the effects of sericin on corneal wound healing in OLETF rats. Corneal wounds were prepared by removal of…
Here we report the synthesis and the liquid crystalline properties of a new class of thienoviologen salts of the dication series 4,4′-(2,2′-bithiophene-5,5′-diyl)bis(1-alkylpyridinium)++ (mV++s) having different alkyl-chain lengths (m = 9–11). As determined by DSC, polarized optical microscopy and X-ray diffraction an…
A new tunable luminescent family of heterocyclic aromatic compounds containing boron has been prepared and characterized through NMR spectroscopy, mass spectrometry, absorption and fluorescence spectroscopy as well as structural study using single crystal X-ray crystallography. Spectroscopic properties of the new comp…
The interactions of ethylene glycol with a partially reduced rutile TiO2(110) surface have been studied using temperature programmed desorption (TPD). The saturation coverage on surface Ti rows is determined to be 0.43 monolayer (ML), slightly less than one ethylene glycol per two Ti sites. Most of the adsorbed ethyle…
Abstract An experimental prototype is built to study the application of using the thermoelectric cooler (TEC) to extract water from air for daily consumption. This paper presents the experimental evaluation of parameters that influence the amount of water, which can be collected from condensation of water vapour in th…
The paper summarizes our main results obtained on the effect of Lead Bismuth Eutectic (LBE) on the low cycle fatigue behaviour at 300 °C of the T91 martensitic steel and of the 316L austenitic stainless steel. The low cycle fatigue behaviour is studied at 300 °C in air and in oxygen saturated LBE on non corroded (as r…
The synthesis of highly active acid catalysts supported on ordered mesoporous materials has eluded chemists until 1998, when Wim M. Van Rhijn et al. explored three different routes to tether sulfonic acid on mesoporous silica. This viewpoint sheds light on this landmark and explores its significant impact on material…
Textured, dense, polycrystalline Ti3AlC2 ceramics was fabricated by spark plasma sintering (SPS) of plate-like Ti3AlC2 powder synthesized by a reactive SPS-heat treatment of elemental Ti, Al and carbon black powders. The relative density was found to exceed 99% for samples sintered at 1573 K. The Lotgering orientation…
