The diffusion of cations from La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-δ (LSCF) into Ce 0.9 Gd 0.1 O 1.95 (CGO) upon co-sintering the two materials is well known. The effect, if any, on the electrochemical properties of the CGO is not yet known. This work attempts to simulate the interaction of CGO with the cations from LSCF b…
A novel type of nano template was prepared by loading a Ziegler–Natta catalyst on nanosized carbon spheres for ethylene polymerization to form nanosized polyethylene (PE) particles; triethylaluminum (AlEt 3 ) was used as a co-catalyst. The results revealed that the nano templates were spherical and their average diame…
Graphene nanobelts (GNBs) as a new class of quasi two dimensional materials that have attracted much research interest in the last few years. Nanobelts are known to show excellent field emission characteristics. On the other hand the scrolled configurations such as graphene nanobelts configuration indicate more stable…
Inspired by the crucial role of nature hydrophobic regions in highly efficient enzymatic catalysis, this work proposes a simple but valid catalyst-design strategy by simply employing the interlayer region of layered double hydroxides (LDHs) to mimic the bilayer structure of nature phospholipids. The interlayer region…
Electrochemical properties of MnO 2 /multiwall carbon nanotube (MWCNT) composites were investigated by using cavity microelectrodes (CME). Electrochemical kinetics of the MnO 2 /MWCNT composites were studied by analyzing the scan rate dependence of voltammetric charge, which was measured by cyclic voltammetry (CV) at…
ABSTRACT Polythiophene–dodecylbenzenesulfonate/antimon oxide nanocomposite was synthesized via in situ chemical oxidative polymerization method at room temperature in aqueous media, and its capability for the removal of lead ions from aqueous solution was studied. Product was characterized by Fourier transfer infrared…
Dierent aspects of critical behaviour of magnetic materials are presented and discussed. The scaling ideas are shown to arise in the context of purely magnetic properties as well as in that of thermal properties as demonstrated by magnetocaloric eect or combined scaling of excess entropy and order parameter. Two non-s…
ABSTRACT Montmorillonite was modified with N,N′‐dimethyl‐N‐dodecyl methacryloxylethyl ammonium bromide (DMAEA–DB), and cetyl trimethyl ammonium bromide (CTAB) as the intercalation agent. Then, a series of different types of superabsorbent composites based on the monomers acrylic acid (AA), acrylamide (AM), and organic…
Abstract Fluorine-incorporated hydrogenated fullerene-like nanostructure amorphous carbon films (F-FLC) were synthesized by employing the direct current plasma enhanced chemical vapor deposition (dc-PECVD) technique using a mixture of methane (CH 4 ), tetra-fluoromethane (CF 4 ), and hydrogen (H 2 ) as the working gas…
In this paper we report how dielectric spectroscopy can help in creating of dual-frequency nematic liquid crystals. Dual-frequency nematic liquid crystals is new class of liquid crystal materials. Such mixture is usually formed by a combination of many components (even more than 10), which can be split into two groups…
A novel and convenient synthetic method for the preparation of α,ω-bis(2,6-dimethylphenol)-poly(2,6-dimethyl-1,4-phenylene oxide) (PPO-2OH) oligomer in water is presented. It is based on the oxidative copolymerization of 2,6-dimethylphenol (DMP) and aromatic diols in the presence of Cu-ethylene diamine tetraacetic aci…
Genes encoding 3-hydroxybutyrate oligomer hydrolase (PhaZc) and 3-hydroxybutyrate dehydrogenase (Hbd) were isolated from Paracoccus denitrificans. PhaZc and Hbd were overproduced as His-tagged proteins in Escherichia coli and purified by affinity and gel filtration chromatography. Purified His-tagged proteins had mole…
In this study, the regulator MalR (Saci_1161) of the TrmB family from Sulfolobus acidocaldarius was identified and was shown to be involved in transcriptional control of the maltose regulon (Saci_1660 to Saci_1666), including the ABC transporter (malEFGK), α-amylase (amyA), and α-glycosidase (malA). The ΔmalR deletion…
A new strategy to prepare core/shell Janus photonic crystal (PC) microspheres with reversible optical spectrum property is demonstrated. The microfluidic technique was employed to generate the uniform core/shell PC microspheres containing nanogels aqueous suspension. Under centrifugal force, the nanogel particles homo…
The hard template approach for preparing porous materials allows one to be able to control pore size and particle morphology. However, the cost of this method is a crucial factor for mass production. In this work, commercially available low-cost hydrophobic CaCO3 spheres (HCS) of different particle sizes were used as…
Biosynthesis of metal nanoparticles using microorganisms is an important area of research in nanobiotechnology, which is an emerging eco-friendly science of well-defined sizes, shapes and controlled monodispersity. The present study proposed a green process for the extracellular production of silver (Ag) and gold (Au)…
Agricultural mulch film of poly(lactic acid) (PLA) has been prepared under industrial conditions by the extrusion blown film method with modified properties using poly(hydroxibutyrate) (PHB) and reactive compatibilizer maleic anhydride (MA). Processing parameters and blend composition have been optimized based upon pr…
This study deals with the fabrication of composite matrix from saw dust (SD) and recycled polyethylene terephthalate (PET) at different ratio (w/w) by flat-pressed method. The wood plastic composites (WPCs) were made with a thickness of 6 mm after mixing the saw dust and PET in a rotary type blender followed by flat p…
We demonstrated that chemical vapor deposition of graphene on Cu films strongly enhances their thermal diffusivity and thermal conductivity. Deposition of graphene increases the thermal conductivity of 9 micrometer (25 micrometer) thick Cu films by up to 24% (16%) near room temperature. Interestingly, the observed imp…
