A simple technique is described for constructing a glucose sensor so that enzymes, glucose oxidase (GOD) was immobilized by cross-linking via glutaraldehyde 0.1% at 0.1 M phosphate buffer with 7.0 pH in a polyaniline and poly(aniline-co-2anilinoethanol) thin films, which were electrochemically deposited on a platinum…
To reveal the smelting reduction mechanism of chromium ore for producing stainless steel in converter, the dissolution behaviour of chromium ore in CaO–SiO2–MgO–Al2O3 slag system was studied by laboratory experiments, and the effects of different temperatures and slag compositions on the dissolution rate of chromium o…
Polymer matrix composites reinforced with metal powders have complex microstructures that vary greatly from differences in particle size, morphology, loading fractions, etc. The effects of the underlying microstructure on the mechanical and wave propagation behavior of these composites during dynamic loading condition…
The molecular design of electron donor conjugated polymers with accurate optoelectronic properties for efficient bulk heterojunction photovoltaic devices has attracted a lot of attention worldwide. Ideally, the polymer should have i) appropriate photon harvesting properties, ii) frontier orbitals that allow both, effi…
The hexagonal phase MoSi2 was grown using MoS2 powder as the source material by the molten salt method. The structural and morphological properties of the resultant silicides are characterized. As a comparison, the structural and compositional characterizations were made for the Mo-silicides grown on a Mo substrate an…
An ascending bubble is deformed by fluid loads while surface tension drives it towards a spherical shape. In contrast to a priori prescribed constant shapes, coupling of the particle shape to the surrounding liquid is realized here in the framework of an immersed boundary method. A method is proposed where the bubble…
In this paper, a new non-lead machinable austenitic stainless steel was investigated. The metallurgical properties, machinability and mechanical properties of the developed alloy were compared with those of the conventional austenitic stainless steel 321. The results have shown that the presence of machinable additive…
The effect of V2O5 addition on the aqueous tape casting of Li1.075Nb0.625Ti0.45O3 microwave ceramics has been investigated. The isoelectric point of the ceramic particles moved slightly toward more acid region after the dispersant absorbed on the particles, while the zeta potential increased significantly. The rheolog…
First principles calculations of the structural and electronic properties of AlAs, InAs and their alloy AlxIn1–xAs have been performed using the full-potential linear muffin-tin orbital (FP-LMTO) [1] method within density functional theory (DFT) [2,3]. We used the local density approximation (LDA) [4] within the gener…
A solution-processed photosensitive passivation layer with a low dielectric constant (PPLD) has been developed for an a-Si thin film transistor. The PPLD has three highly important properties: a low leakage current, low water absorption, and high-transparency. In addition to providing passivation, the PPLD doubles as…
Mature prion protein (PrP) is a 208-residue polypeptide that contains a single disulfide bond. We report an alternative method to purify recombinant mouse PrP produced in Escherichia coli. Bacterial inclusion bodies were solubilized in a buffer containing 2 M urea at pH 12.5. The solubilized protein was rapidly purifi…
Protein-protein complexes play an important role in the physiology and the pathology of cellular functions, and therefore are attractive therapeutic targets. A small subset of residues known as “hot spots”, accounts for most of the protein-protein binding free energy. Computational methods play a critical role in iden…
Resonant infrared matrix-assisted pulsed laser evaporation (RIR-MAPLE) is a variation of pulsed laser deposition that is useful for organic-based thin films because it reduces material degradation by selective absorption of infrared radiation in the host matrix. A unique emulsion-based RIR-MAPLE approach has been deve…
The Bi1.5MgNb1.5O7 (BMN) thin films were prepared on platinum coated sapphire by rf magnetron sputtering deposition. Effects of substrate temperature, sputtering ambient and post rapid thermal annealing on structure, morphologies, and dielectric properties of films were investigated. Thin films have cubic pyrochlore s…
In our attempts to combine catalytic chain transfer polymerisation (CCTP) with ring-opening polymerisation (ROP), we investigated the homopolymerisation and copolymerisation behaviour of epoxidised CCTP-derived (macro)monomers. Attempts at polymerisation and copolymerisation proved futile. However, some interesting en…
We analyze a finite-thickness metal-semiconductor-metal waveguide to be utilized as an ultra-compact plasmonic modulator in optoelectronic integrated circuits. The InP-based semiconductor core allows electrical control of signal propagation. We show that using thin metal layers instead of thick ones we can obtain high…
The efficiency of Luminescent solar concentrators is still rather low, due to several loss-mechanisms, which are maximised by self-absorption. We demonstrate that use of type-II semiconductor hetero-nanocrystals may offer a solution to the self-absorption problem.
The Al–O–C–N system is known as a kind of Al2O3-based ceramic material with various different chemical compositions and structures. Considering its superior physical and mechanical properties, the corresponding one-dimensional Al–O–C–N system may have huge potential applications in future nanodevices. Herein, for the…
The effect of p-layer and i-layer characteristics such as thickness and doping concentration on the electrical behaviors of the a-Si:H/a-SiGe:H thin film heterostructure solar cells such as electric field, photogeneration rate, and recombination rate through the cell is investigated. Introducing Ge atoms to the Si lat…
Surface plasmon resonance (SPR) is a quantum electromagnetic phenomenon arising from the interaction of light with free electrons at a metal-dielectric interface. SPR has emerged as a powerful optical sensor based on the sensing of the change in refractive index of a medium adjacent to the metal surface layer. In the…
