The aging of a nanocrystalline equiatomic ZnSe alloy produced by mechanical alloying was investigated using X-ray diffraction (XRD) and differential scanning calorimetry (DSC) techniques. The measured XRD patterns showed that Se atoms…
We use hexagonal mesophases made of oil-swollen surfactant-stabilized tubes arranged on a triangular lattice in water and doped with metallic salts as templates for the radiolytic synthesis of nanostructures. The nanostructures formed in…
Ce/Cr codoped TiO2 nanoparticles were synthesized using sol gel and Pechini methods with heat treatment at 400 C for 4 h. A conventional sol gel process produced well-crystallized anatase, while Pechini synthesis yielded less ordered…
DNA is an astonishing material that can be used as a molecular building block to construct periodic arrays and devices with nanoscale accuracy and precision. Here, we present simple bead-spring model of DNA nanostars having three, four and…
Manganese-doped zinc sulfide nanocrystalline thin films were synthesized using a low-temperature chemical bath deposition and deposited on glass substrates for controlled durations using triethanolamine (TEA) as a complexing and capping…
Platinum diselenide (PtSe${_2}$) is a two-dimensional (2D) material with outstanding electronic and piezoresistive properties. The material can be grown at low temperatures in a scalable manner which makes it extremely appealing for many…
In this review, room temperature (RT) precipitation of the nanocrystalline-ceria (nc-ceria) re-dispersed and subsequently size-reduced by 20 kHz probe sonication in 25 % ethylene glycol/ 75 % DI-water mixed media is investigated. The…
In this work, the structural and magnetic properties of the gold-coated FePt nanoparticles synthesized from high-temperature solution phase are presented. The amount of gold was optimized to obtain most of the FePt particles coated. The…
In a previous study, structure of silica gels prepared in a high magnetic field was investigated. While a direct application of such anisotropic silica gels is for an optical anisotropic medium possessing chemical resistance, we show here…
The microstructural development in H13 tool steel upon nitriding by an ion beam process was investigated. The nitriding experiments were performed at a relatively low temperature of about 400\deg C and at constant ion beam energy (400 eV)…
Crystallographic texture engineering in ceramics is essential to achieve direction-specific properties. Current texture engineering methods are time-consuming, energy extensive, or can lead to unnecessary diffusion of added dopants. Herein,…
Controlled chemical transformation of nanostructures is a promising technique to obtain precisely designed novel materials which are difficult to synthesize otherwise. We report high-temperature vapor phase anion exchange reactions to…
Titanic acid nanotubes (with a chemical formula H2Ti2O4(OH)2, abbreviated as TANTs) were synthesized by the hydrothermal method using commercial TiO2 nanoparticle powder (P25, Degussa, Germany) including anatase and rutile phase as a…
Phase transition from anatase to rutile for the 70nm TiO2 crystallite has been investigated by annealing at different temperatures followed by TDPAC measurement of these TiO2 crystallites adsorbed with 181Hf tracer. The width of the peaks…
Nano oils synthesized by dispersing dielectric nanostructures counter common intuition as such nano oils possess substantially higher positive dielectric breakdown voltage with reduced streamer velocities than the base oils. Nano oils…
Highly crystalline TiO2 nanostructures were prepared through a facile inorganic acid-assisted hydrothermal treatment of hexagonal-structured assemblies of nanocrystalline titiania templated by cetyltrimethylammonium bromide (Hex-ncTiO2/CTAB…
PCPDTBT nanostructures have been synthesized via template-assisted method and polymer-melt technique. The morphological, optical and structural properties of the PCPDTBT have been investigated. Melting polymer was used as a driving force to…
Monodispersed strontium titanate nanoparticles were prepared and studied in detail. It is found that ~10 nm as-prepared stoichiometric nanoparticles are in a polar structural state (with possibly ferroelectric properties) over a broad…
Three distinct samples were proceed through synthesis utilizing the hydrothermal method to develop tin dioxide (SnO2) nanoparticles. Consistency in all other parameters was ensured by maintaining a constant temperature and time throughout…
Sol gel obtained YZS (Yttria Stabilized Zirconia) nanocrystals have different morphologies when they grow on an $\alpha$-alumina substrate after thermal treatment. When the substrate has planar defects, the nanocrystals grow in height and…
