Alumina doped nickel ferrite nano-particles have been synthesized by the combustion route. Characterization of the products carried out using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Magnetic and surface properties of the as prepared ferrites were determining by using vibrating sample magnetomet…
Two nanofiber coatings, namely polyvinyl alcohol (PVA) and polyvinyl chloride (PVC) were prepared and deposited on aluminum surface using electrospinning technology. The coating layers were characterized using thermogravimetric analysis (TGA), optical (OM) and scanning electron (SEM) microscopes. The SEM images showed…
The inhibition potentials of lignin extract of sun flower was investigated by evaluating the corrosion behaviour of medium carbon low alloy steel immersed in 1M H2SO4 solution containing varied concentration of the extract. Mass loss, corrosion rate, and adsorption characterization were utilized to evaluate the corros…
A detailed analysis of photophysical characteristics of mono-, double-and triple-decker complexes of Er III , Yb III and Lu III with 2, The values of the quantum yields and the rate constants of molecular fluorescence and intersystem crossing of the compounds were estimated. It was discovered that the solutions of the…
The plant pulp consists of a cellulose nanofiber or a cellulose microfibril bundle. Since nanofibers are bundles of semi-crystalline extended cellulose chains, their thermal expansion is as low as that of quartz whilst their strength is five times that of steel. Recently, due to the risk of depletion of oil reserves a…
was synthesized in Emaraldine form by in situ chemical oxidation method by using Ammonium perdisulphate as oxidizing agent. The XRD pattern indicates that PANI is a semi crystalline solid with d-spacing 4.801 and 4.358 . The SEM results show that the particle size lies as an average of 80 nm and length 550nm. Similarl…
It is imperative to understand about the properties of biodegradable composites and raw materials used in making such composites which are being used for biomedical, automobiles, packaging and other engineering applications. Production of biodegradable composites from renewable sources is a challenging task for resear…
Lattice mismatch with a substrate and difference in coefficient of thermal expansion to the substrate induces stress and deformations in crystalline structure of epitaxially grown layers. In this work, we present results of structural study of gadolinium oxide and erbium oxide grown on silicon (111) substrate applying…
Varying amounts of dispersed multiwalled carbon nanotubes in NiO have been used to develop composites that absorb the solar energy very well but lose very little through emission. Determination of absorptance, αsol , and emissivity, εther , from such selective solar absorbers shows that the optimum efficiency of 71% c…
We present a novel approach to preparing bismuth acceptor doped barium titanate nanocrystal formulations that can be deposited in conjunction with polymers in order to prepare a thin film nanocomposite dielectric that exhibits desirable capacitor characteristics. Exploring the limits of dielectric function in nanocomp…
A higher order convective Cahn--Hilliard-type equation that describes the faceting of a growing surface is considered with periodic boundary conditions. By using a Galerkin approach, the existence of weak solutions to this sixth order partial differential equation is established in $L^2(0,T;\dot{H}^3_{per})$. Addition…
Layered double hydroxide [LiAl2(OH)6]X (LiAl–X; X = Cl, Br) 1D nanorods have been prepared in a topotactic reaction involving the intercalation of LiX (X = Cl, Br) into a rod-like form of gibbsite. The nanorod LDH products adopt a hexagonal prismatic morphology with the brucite-like layers stacking along the long rod…
A fast and cost-effective approach for the synthesis of substrates used in surface enhanced Raman scattering (SERS) has been developed using galvanic displacement. Deposition of silver onto commercially available Cu foil has resulted in the formation of multiple hierarchical structures, whose morphology show dependenc…
Micro/nano-structured poly (3,4-ethylenedioxythiophene) (PEDOT) has shown a broad range of potential applications in various fields. In this work, PEDOT micro/nanostructures including hollow spheres and double-layer bowls, which exhibit typical hierarchical three-dimensional micro-structures assembled from one-dimensi…
Semimagnetic Pb(1-x)Mn(x)Se nanocrystals were synthesized by a fusion method in a glass matrix and characterized by optical absorption (OA), atomic/magnetic force microscopy (AFM/MFM), and photoluminescence techniques. MFM images strongly indicated the formation of Pb(1-x)Mn(x)Se magnetic phases in the glass system. Q…
In this work, a miniemulsion template method was proposed to prepare a porous polymeric monolith with an inter-connected structure. The preparation of a porous monolith with sub-micrometer pore structure was realized and showed great potential to prepare a nanoscale porous monolith with an inter-connected structure. A…
Tumor targetability and stimuli responsivity of drug delivery systems (DDS) are key factors in cancer therapy. Implementation of multifunctional DDS can afford targetability and responsivity at the same time. Herein, cholesterol molecules (Ch) were coupled to hyaluronic acid (HA) backbones to afford amphiphilic conjug…
Biocompatible and biodegradable nanogels with a branched structure designed as potential carriers for drug delivery are reported here. The nanogels were prepared by the reaction of 3,6-dioxaoctan-1,8-diyl bis(ethylene phosphate) (TEGDP) with tris(2-aminoethyl)amine (TREN) in an ionic liquid containing miniemulsion; th…
Self-assembled monolayers (SAMs) of alkanethiolates on gold are chemically defined substrates that can be used to evaluate the effects of an immobilized biomolecule. However, the types of biomolecules that can influence stem cell behavior are numerous and inter-related, and efficient experimental formats are a critica…
Active laser arrays, of arbitrary pattern, were created by inkjet deposition of self-assembled photonic structures in the form of dye-doped chiral nematic liquid crystals.
