A strongly coupled mesoporous SnO2–graphene hybrid has been prepared via direct nucleation, growth, and anchoring of a SnO2 nanocrystal on graphene substrate under microwave irradiation followed by heat-treatment. Investigations reveal that the well-dispersed SnO2 nanocrystals with a uniform particle size of 3–5 nm ar…
A process for obtaining a low temperature, UV curable inorganic–organic hybrid coating having excellent photoactive properties which is suitable for glass surfaces such as solar cell covers, automobile rear view mirrors and several electronic devices is presented. Nano titania sol having an average particle size of 19…
In this work, we demonstrate a general and eco-friendly self-etching route for the construction of a series of yolk-shell Au@metal silicate nanoreactors. Different from previous conventional synthesis routes to remove the hard silica templates, a facile, mild, and green hydrothermal method is employed in our system ba…
Two aqueous dispersions of anionic and nonionic polystyrene (PS) latex nanospheres were prepared via activators generated by electron transfer (AGET) atom transfer radical polymerization (ATRP) and reverse ATRP in microemulsions using sodium dodecyl benzene sulfonate (SDBS) and polyoxyethylene (20) oleyl ether (Brij 9…
Shape-controlled synthesis of magnetite nanoparticles has been successfully carried out through simple phase transformation via a modified polyol process using akaganeite (β-FeOOH) as the precursor. Different shapes of magnetite nanoparticles, including solid nanospheres and solid and hollow nanoellipsoids, could be o…
We have designed and synthesized a novel fluorescent molecular probe using the Cu(i)-catalyzed Huisgen cycloaddition of 1,3-diethynyl-6-fluoroisoquinoline with 1-(2-azidoethyl)pyrrolidine. This water soluble "click" fluorescent chemosensor displays good sensitivity towards heavy and transition metal ions. It shows pro…
Metals are essential in biochemistry, with highly regulated localisation and concentration. To continue elucidating the impact of inorganic physiology on cellular process in health and disease requires development of suitable eukaryotic models and experimental approaches. The multicellular organism Caenorhabditis eleg…
Core-shell structured NiO@TiO2 nanopowders for application as anode materials for lithium ion batteries are prepared by one-pot flame spray pyrolysis from aqueous spray solution containing Ni and Ti components. A new formation mechanism of the core-shell structured nanopowders in the flame spray pyrolysis is proposed.…
The aim of this study is to investigate whether MRF steel structures that have been designed based on seismic codes, are able to resist progressive collapse with damaged columns in different locations under seismic loading. For this purpose, 3-D and 2-D push-over analysis of structures is carried out. The progressive…
Herein we report a robust and easy method for detecting cesium metal ion (Cs(+)) in partially aqueous solutions using the fluorescence quenching of 2,4-bis[4-(N,N-dihydroxyethylamino)phenyl]squaraine. This squaraine dye was found to be both highly sensitive (low limits of detection) and selective (limited response to…
Two new indolo[3,2-b]carbazole derivatives (DPDT-ICZ and DNDT-ICZ) with multifunctionality were designed and synthesized. They were employed as deep-blue emitters, hole-transporting materials and hosts to fabricate organic light-emitting devices (OLEDs). The devices which used them as emitters displayed deep-blue emis…
In this study, we investigated the iron sulphides phase transitions resulting from steel corrosion under sulphate-reducing-bacteria conditions. Experiments were conducted at 30 °C from 7 to 240 aging days. Culture batch experiments were conducted with steel coupons, clay and groundwater amended with lactate to simulat…
In this study, ZnO nanoparticles (ZnO NPs) were conformally covered on the surfaces of ZnO nanowires (ZnO NWs) with high diffusion coefficient (1.2 × 10(-2) cm(2) s(-1)) to make a composite photoanode. By using N719 to sensitize the composite photoanode, the conversion efficiency can reach 7.14%.
In this study, we constructed an inverse opal structured hematite (IOS α-Fe2O3) as the photoanode of a photoelectrochemical (PEC) cell for efficient solar water splitting via a simple electrochemical process. At the same time, a series of affecting factors (template particle size, electrodeposition time and annealing…
Fluoride detection through hydrogen bonding or deprotonation is most commonly achieved using amide, urea or pyrrole derivatives. The sensor molecules are often complex constructs and several synthetic steps are required for their preparation. Here we report the discovery that simple arylaldoximes have remarkable prope…
Co3O4 octahedral particles, with lengths of ~70 nm and widths of ~60 nm, were hydrothermally synthesized under the assistance of triphenylphosphine (PPh3). X-ray powder diffraction (XRD) showed that the Co3O4 octahedra belong to the cubic crystal system. Scanning electron microscopy (SEM) and high-resolution transmiss…
The interaction between triblock copolymer Pluronic P123 and anionic surfactant Aerosol OT (AOT) has been studied using dynamic light scattering (DLS) and small angle neutron scattering (SANS). The copolymer/surfactant system has been investigated at a constant copolymer concentration of 0.5 wt% and with varying surfa…
N‐doped TiO2 nanorod arrays (NRAs) were prepared by annealing the TiN nanorod arrays (NRAs) which were deposited by using oblique angle deposition (OAD) technique. The TiN NRAs were annealed at 330°C for different times (5, 15, 30, 60, and 120 min). The band gaps of annealed TiN NRAs (i.e., N‐doped TiO2 NRAs) show a s…
Multicomponent Fe(II)-iminopyridine-based self-assemblies have been synthesized with variably sized internal functionality. Larger internal functions provide increased strain to the complex and confer diastereocontrol upon the assembly process. Complete diastereocontrol is possible upon the introduction of large achir…
The adsorption behavior of acid orange-7 (AO-7) on aluminum oxide nanoparticles (ANP) generated by sol-gel method has been investigated to understand the physicochemical process involved and to explore the potential use of nano particles in textile effluent treatment and management. The results revealed that ANP can r…
