Large quantities of single-crystal iron submicron cubes with controllable dimensions and surface structures were synthesized by a facile low-temperature solution reduction approach under normal atmosphere. The influence of kinetic parameters such as NaOH concentration, reaction temperature, reaction time, species of s…
Multi-walled carbon nanotubes (MWCNT) have won enormous popularity in nanotechnology. Due to their unusual, one dimensional, hollow nanostructure and unique physicochemical properties they are highly desirable for use within the commercial, environmental and medical sectors. Despite their wide application, little info…
Long gold rods were directly grown on a reduced graphene oxide (RGO) surface by seed-mediated and seedless approaches for the fabrication of a novel Raman scattering platform. The Raman scattering signal from RGO was significantly enhanced by 34-fold at the tip of the grown gold rod.
Reaction of Co(NCS)(2) with pyridine (pyr) in aqueous solution at room temperature leads to the formation of the pyridine-rich 1:4 compound of composition [Co(NCS)(2)(pyridine)(4)] (1) reported recently. On heating, the pyridine-rich 1:4 compound transforms into its corresponding pyridine-deficient 1:2 compound of com…
Recently, nanodiamond particles (ND) have emerged as a promising tool in the field of nanobiotechnology. However, studies about the impact of ND on living organisms are still limited to raw materials and primarily confined to in vitro studies. In this work, we investigated the cytotoxicity and in vivo toxicity of ND c…
Cobalt talc nanolayers dispersed in silica aerogel constitute an active nanocomposited material with outstanding catalytic properties for the generation of hydrogen by ethanol steam reforming at low temperature. Delamination of talc particles into individual nanolayers of ca. 1.8 nm thick readily occurs under the refo…
A mild photo-assisted reduction method was developed to fabricate large-area, uniform reduced graphene oxide-TiO(2) films and micropatterns on various substrates in air at room temperature from a composite insulating film of graphene oxide sheets and TiO(2) nanoparticles, with a conductivity (0.5-2 Omega cm) comparabl…
In this study we have revealed that spiropyrans and spirooxazines, which have long been believed to be non-photochromic in the solid state, are generally photochromic in the solid state at least at low temperatures and that their photoreactivity increases greatly as the temperature is lowered.
Well-defined ceria nanocubes covered by oleic acid with exposed {100} facets have been synthesized and exhibited exclusive selectivity for the oxidation of toluene to benzaldehydes in liquid phase by O(2).
A highly processable form of polyaniline was synthesized and used to form pure polyaniline and polyaniline–polysulfone ultrafiltration membranes by nonsolvent induced phase inversion. Blends containing up to 75% polyaniline were 10–20% more permeable than pure polysulfone membranes, while pure polyaniline membranes we…
BACKGROUND: Recent studies have shown the potential suitability of magnesium alloys as biodegradable implants. The aim of the present study was to compare the soft tissue biocompatibility of MgCa0.8 and commonly used surgical steel in vivo. METHODS: A biodegradable magnesium calcium alloy (MgCa0.8) and surgical steel…
Synthesis and characterization of magnetic nanoparticles with excellent size control are showed here. Their functionalization using an amphiphilic polymer is also described. This strategy allows the stabilization of magnetic nanoparticles in aqueous solvents and in addition, the polymer shell serves as a platform to i…
A bifunctional single-component healant, glycidyl methacrylate (GMA), is encapsulated and employed for fabricating self-healing epoxy materials. The released GMA is able to rebond cracked portions at room temperature through hydrogen and covalent bonds, and hence recover fracture toughness with high efficiency. The ma…
The conjugation of zwitterionic phosphorylcholine onto gold nanorods leads to enhanced and selective uptake within cancer cells.
Gold is known to be the noblest of all metals because of the relativistic stabilization of its outer 6s orbital. The relativistic effects also lead to destabilization of the 5d orbitals, reducing the 6s-5d energy gap and enhancing s-d hybridization. Therefore, in contrast to its lighter congeners, gold exhibits signif…
Abstract One-step lateral flow test is recommended as the first line screening of syphilis for primary healthcare settings in developing countries. However, it generally shows low sensitivity. We describe here the development of a novel fluorescent POC (Point Of Care) test method to be used for screening for syphilis.…
Abstract The growing demand for electro mobility together with advancing concepts for renewable energy as primary power sources requires sophisticated methods of energy storage. In this work, we present a Li ion battery based on Si nanowires, which can be produced reliable and cheaply and which shows superior properti…
Abstract Bio-compatible magnetic fluids having high saturation magnetization find immense applications in various biomedical fields. Aqueous ferrofluids of superparamagnetic iron oxide nanoparticles with narrow size distribution, high shelf life and good stability is realized by controlled chemical co-precipitation pr…
Abstract Titanium oxide compounds TiO,Ti2O3, and TiO2 with a considerable extent of nonstoichiometry were fabricated by pulsed laser ablation in water and characterized by X-ray/electron diffraction, X-ray photoelectron spectroscopy and electron energy loss spectroscopy. The titanium oxides were found to occur as nano…
