The influence of the polysaccharide charge distribution on the structure, thickness, and charge reversal of the interfacial layers, formed by adsorbed positively charged protein and oppositely charged polysaccharide, has been investigated using a lattice-based self-consistent field (SCF) approach. We compare the adsor…
Infiltration of a polymeric nickel oxide precursor into a sintered porous ytrria -stabilized zirconia (YSZ) skeleton is a promising approach to achieve redox stable solid oxide fuel cells.In order to ensure that the porous YSZ skeleton was mechanically strong enough to withstand the stresses caused by the volumetric e…
Synthetic polymeric materials are established as being central to many modern approaches to medical treatments such as biomaterial induced tissue regeneration or drug eluting implants. Cytocompatible, antifouling materials, based on hydrophilic polymers such as poly(ethylene glycol), have been widely studied as a ‘bla…
The effects of Pu content on the dissolution rate and the mass of the insoluble residue of irradiated mixed oxide fuel were studied. On the basis of the kinetic analysis assuming the surface-area model, the dissolution rate was found to decrease exponentially with an increase of the Pu content, but those were estimate…
Abstract: Shaped charges are used for the penetration of targets in all three dimensions of warfare – land, air and naval. With fillings of high explosives compositions inside, they generate a thin high velocity metal jet, which can perforate the targets. Shaped charges can penetrate tanks with thick armour protection…
The lattice, the band gap and the optical properties of n-type ZnO under uniaxial stress are investigated by first-principles calculations. The results show that the lattice constants change linearly with stress. Band gaps are broadened linearly as the uniaxial compressive stress increases. The change of band gap for…

Creating sublithographic scale uniform nanowires for large area is an important issue for nanowire-based various device applications. Although anodic aluminium oxide (AAO) membrane is a promising technique, existing attached AAO membrane mask methods have not been able to fabricate such small nanowires for large areas…
Selective protein fouling on block copolymer micelles with well-known potential for tumour-targeting drug delivery was evidenced by using dynamic light scattering measurements. The stability and interaction of block copolymer micelles with model proteins (BSA, IgG, lysozyme and CytC) is reported for systems featuring…
Nanocrystalline nickel-molybdenum (Ni-Mo) alloy thin films and nanowires array were synthesized in acidic aqueous solution containing citric acid using an induced co-deposition technique. Cross-sectional scanning ion microscope (SIM) images of the electrodeposits revealed that pure Ni consists of large crystal grains…
The increasing applications of surface-enhanced Raman scattering (SERS) has led to the development of various SERS-active platforms (SERS substrates) for SERS measurement. This work reviews the current optimization techniques available for improving the performance of some of these SERS substrates. The work particular…
Materials with disordered structures have a crucial role in the rapid development of new technologies. Improvement of these materials for particular application, as well as preparation of novel composites is based on a thorough understanding of the basic mechanisms of charge carrier transport. Among various classes of…
We report the synthesis of several unconventional 0-, 1- and 2-dimensional copper sulfide nanostrucutures by the chemical vapor deposition method. The key factor for morphology and structure control of a variety of copper sulfide products is the tuning of deposition and growth temperature to fit for the surface energy…
We synthesized Eu(III) and Sm(III) complexes with tridentate phosphine oxide ligands, Eu(hfa)(3)(TPPM) and Sm(hfa)(3)(TPPM) (hfa: hexafluoroacetylacetonato, TPPM: tris(diphenylphosphinyl)methane), and we then examined their luminescent properties. In the complexes the Eu(III) and Sm(III) centres were fully surrounded…
Molecular design, chemical synthesis, and biological evaluation of several designed organic molecules, which target-selectively degrade proteins upon photo-irradiation, are introduced. The designed molecules for protein photo-degradation include 2-phenylquinoline-steroid hormone hybrids and porphyrin derivatives, both…
Many divertor design studies for future fusion reactors rely on helium gas cooling. In these concepts, pressurized tubes or channels had to be operated at maximum temperatures between 1000 °C and 1300 °C while the lowest operating temperature is preset by the coolant inlet or by specific start-up and maintenance condi…
The toxicity of QD has been extensively studied over the past decade. However, the potential toxicity of QDs impedes its use for clinical research. In this work, we established a preantral follicle in vitro culture system to investigate the effects of QD-Transferrin (QDs-Tf) bioconjugates on follicle development and o…
Protein nanogels were synthesized via a one-step reaction procedure by crosslinking urokinase with benzaldehyde bifunctionalized poly(ethylene glycol). The crosslinked architecture significantly enhances the stability of urokinase against enzyme degradation in comparison with the core–shell structural PEGylated protei…
We present the results based on the electrooptic and dielectric studies in cadmium sulphide (CdS) nanorods/ferroelectric liquid crystal mixtures. Doping of CdS nanorods increases the spontaneous polarization and response time, which due to large dipole-dipole interaction and increase in anchoring energies exists betwe…
The photoluminescence(PL) spectra of ZnCuInS quantum dots(QDs) were measured in the temperature range from 100 to 300 K.The temperature dependences of the PL energy,linewidth,and intensity of the ZnCuInS QDs were investigated in detail.An anomalous increase in band gap of ZnCuInS QDs with temperature was observed.The…
