SrBi2Nb2O9 nanoplates were successfully synthesized by a hydrothermal method for the first time, using Sr(NO3)2, Bi2O3, and Nb2O5 as the starting materials and KOH as the mineralizer. The influences of the reaction conditions on the phases and morphologies of the products were investigated by X-ray diffraction (XRD) a…
Magnesia (MgO) nanoparticles were produced from magnesite ore (MgCO 3 ) using ball mill. The crystalline size, morphology and specific SSA were characterized by X-ray diffraction analysis, transmission electron microscopy and Brunauer-Emmett-Teller method, respectively. MgO nanoparticle-incorporated nylon 6 solutions…
Na 2 SO 4 , Na 2 SO 4 : Li, and Na 2 SO 4 : Li, Eu, Dy phosphors were prepared by using slow evaporation technique followed by subsequent calcination at 400°C for 4 h. Doping with Li + ion stabilized the thenardite phase of host matrix, while codoping with RE 3+ stabilized the phase transformation from stable thenardi…
Abstract Ni‐base metal–intermetallic laminate composites were obtained from in situ reaction synthesis between Ni and Al foils by utilizing plasma activated sintering. The effects of Ni foil thickness on the microstructure and tensile properties of the composites were investigated. The results show that the phases for…
The magnetic and thermal properties of Ce1−xErxAl2 compounds have been studied using specific heat, dc magnetization, and ac susceptibility measurements. All these compounds are isomorphic with the MgCu2 Laves phase, and the lattice parameter decreases almost linearly with the increasing Er concentration x. The dc mag…
By conjugating antibodies on magnetic nanoparticles, target antigens can be quantitatively detected by measuring the magnetic signals of the magnetic nanoparticles due to their association with target antigens. This method of detection is called magnetically labeled immunoassay. The assay characteristics of magnetical…
The thermally stimulated depolarization current (TSDC) technique has been used to study the slow molecular mobility in the amorphous part of the semicrystalline polymer, poly(ethylene oxide) (PEO). Experiments were carried out in the temperature range that includes the glassy state, the glass transformation region and…
The results of spectroscopic studies of the diffraction anomalies (the so-called resonant Wood anomalies) in spatially periodic hybrid structures based on chalcogenide ${\mathrm{Ge}}_{2}{\mathrm{Sb}}_{2}{\mathrm{Te}}_{5}$-coated opal films of various thickness are presented. A theoretical analysis of spectral-angular…
Optimization of thin‐film transistors performance is usually accompanied by an increase of the process temperature. This work presents a method to raise the field effect mobility by a factor of 3 without a change of the process parameters. The modification involves a solution doping process where an ammine zinc comple…
Catalytically synthesized methanol from H2 and CO2 using porous Cu/ZnO aggregates is a promising, carbon neutral, and renewable alternative to replace fossil fuel based transport fuels. However, the absence of surface-engineered model systems to understand and improve the industrial Cu/ZnO catalyst poses a big technol…
In this study, macro-(RAFT) reversible additional fragmental chain transfer agent prepared by reversible additional fragmental chain transfer polymerisation has been incorporated into polymer dispersed liquid crystals (PDLCs). The effects of concentration, molecular weight and glass transition temperature of macro-RAF…
The production of nanoparticles from solution typically involves the use of complex solution additives or particle functionalization with organic ligands to prevent aggregation. Another approach would be to produce the particles within a nanoscale environment, such as inside a micelle. In this contribution, we produce…
A lens consisting of a subwavelength slit engraved into a metal film and surrounded by periodic surface gratings and spatial multiplexing chirped surface gratings (SMCSGs) for focusing light is proposed. The focal length of the lens can be accurately designed and tuned by controlling the periods of the local gratings…
Unfilled and ytterbium (Yb)‐filled cobalt antimony (CoSb 3 ) nanoparticles were synthesized via solvothermal route using sodium borohydride (NaBH 4 ) as a reducing agent. The effect of various amounts of sodium borohydride on the formation of as‐synthesized CoSb 3 nanoparticles with pure phase was investigated. It is…
The effective utilization of graphene in optoelectronic devices requires blending with other semiconductor materials, such as lead chalcogenide nanocrystals, and an understanding of the organic–inorganic interface at the atomic level. In this paper, we present the first report of the successful self-assembly of close-…
In this article, we studied the synthesis of carbon nanotubes (CNTs) by chemical vapor deposition (CVD) over Co3O4, Fe2O3-Co3O4, and NiO-Co3O4 catalyst nanoparticles supported by MgO powder at 600–900°C. The size of the catalyst nanoparticles was controlled by changing metal nitrates concentration in aqueous solution…
Ultrathin silica coating (UTSC) has emerged as an effective way to improve the compatibility and stability of nanoparticles without attenuating their intrinsic optical properties. Exploration strategies to probe the growth process of ultrathin silica shells on the surface of nanoparticles would represent a valuable in…
ABSTRACT The present work describes the synthesis and characterization of polyurethanamide/organo‐montmorillonite bio‐nanocomposites (OBNC) from Linseed oil‐a renewable resource.

We investigate the binding of ammonia on intrinsic and substitutionally doped semiconducting single-walled carbon nanotubes (SWCNTs) on the side walls using density functional calculations. Ammonia is found to be weakly physisorbed on intrinsic semiconducting nanotubes while on substitutional doping with boron its aff…
