This paper considers the standard ecotoxicity tests done so far for assessing the hazards of engineered nanoparticles and potential negative effects that engineered nanoparticles may have on environment. Research and development in nanotechnologies increase strongly and attract substantial funding, but environmental c…

The effect of organo-montmorillonite (OMMT) on the properties of acrylonitrile butadiene rubber/polyvinyl chloride/OMMT (NBR/PVC/OMMT) nanocomposites is studied. Four different types of organo-modified OMMT were examined in NBR/PVC blend systems and an optimum type of OMMT (FMR11) was found by characterizing the mecha…
In recent years, compact spinning technology, recognised as a revolution in ring spinning, has been successfully used in the production of mono-fibre yarns and blended yarns. Under standing the radial distribution of fibres in compact-spun flax-cotton blended yarn is of im portance for improvement in the performance o…
The present investigation deals with the dissolution behavior of pure Copper and its one of the alloy (Cu-27Zn Brass) in Natural Sea water environment at various time, temperature and various concentration of Vitis vinifera seed and skin extract. The inhibition efficiency is markedly higher in Natural sea water with a…
In this study, mechanical and performance analyses of woven fabrics were carried out using objective evaluation techniques. The KES-FB Auto system, the FAST system and Cusick’s Drape Meter were used to evaluate the mechanical properties of the fabrics. The shear, bending, extension, and compression parameters were mea…
We examine the evolution (‘healing’) of the interface between two polymer films at various temperatures below the glass transition temperature, Tg. Specifically, neutron reflectometry is used to study the relaxation of the interface between both unentangled and entangled deuterated polystyrene (d-PS) and hydrogenated…
Bolaamphiphilic zinc porphyrins bearing a 2-pyridylethynyl or 4-methoxyphenylethynyl group, Zn(PyPor) or Zn(ArPor), respectively, were newly synthesized in order to explore the molecular organizing behaviours within the interior hydrophobic layer of aqueous self-assemblies. Well-ordered J-type aggregates of Zn(PyPor)…
Control of molecular and supramolecular properties is used to obtain a new advanced hybrid material based on Prussian blue nanoparticles (PB NPs). This hybrid material is obtained through a self-assembled Layer-by-Layer (LbL) approach combining the advantageous features of β-cyclodextrin (β-CD) polysaccharides, PB NPs…
Preferential grain etching is a problem occurring on aluminum products during alkaline etching prior to anodizing, especially if the etching bath contains small amounts of dissolved Zn. The visually uneven, "grainy" surface is caused by different etch rates for different grains, giving a terracelike surface topography…
-doped was prepared by a high temperature solid-state reaction. The phase formation was confirmed by X-ray powder diffraction measurements. The site-selective excitation and emission spectra were investigated in the region by using a pulsed, tunable, and narrowband dye laser. Two crystallographic sites for ions doped…
Co-crystallization of p-N(CH3)2C6H4CHO and E-4-(4-dimethylaminostyryl)-1-methylpyridinium iodide ([DAMS]I) gives a new solid state form (A), characterized by high non-linear-optical (NLO) activity and quite different from the well known [DAMS]I salt (centrosymmetric and therefore inactive). The X-ray structural charac…
In this study, polypyrrole was deposited on the aluminium in different anions (CO 3 2− , NO 2 − , CrO 4 2− , DBS−). The contribution of anions to formation of polypyrrole film was investigated by using cyclic voltammetry (CV) technique. The effect of polypyrrole film on the corrosion of aluminium was searched in 0.1 M…
Directional controllability of single-walled carbon nanotubes (SWNTs) is an important issue for future nanoelectronics applications. For direct integration of carbon nanotubes with modern electronics, aligned growth of carbon nanotubes on SiO(2)/Si is desirable. We developed a new method to horizontally align SWNTs di…
Metal nanostructures show great applications in chemical sensing, biomedical detection, optical-thermal therapy, and optical communications because of their electromagnetic field enhancement properties at the visible and the near-field infrared wavelengths. Such strong optical field enhancement induced by the localize…
The concentration, activation, and total polarizations of the cathode in a cathode-supported solid oxide fuel cell (SOFC) were theoretically and experimentally investigated. In the theoretical analysis, the exchange current density of the charge transfer was considered to be dependent on the PO2 determined by the prec…
Tissue engineering of various musculoskeletal or cardiovascular tissues requires scaffolds with controllable mechanical anisotropy. However, native tissues also exhibit significant inhomogeneity in their mechanical properties, and the principal axes of anisotropy may vary with site or depth from the tissue surface. Th…
Classical force field simulations and genetic algorithms are used to navigate low-energy configurations of samarium-doped ceria (SDC) at a number of concentrations, up to 20% SDC, such that the experimentally observed peak in ionic conductivity is mapped out in its entirety and fresh insight into samarium's role is re…
The fiber extracted from the husk of a coconut fruit, known as coir fiber, has been extensively investigated as a second phase incorporation into polymer composites. The moderate strength of the coir fiber usually does not represent reinforcement to relatively strong thermoset matrices such as polyester, epoxy and phe…
Recently, the studies on the effects of high magnetic fields on solidification processes have been paid much attention both from the fundamental and applied points of view. With the aid of the enhanced Lorentz force and magnetization effect caused by the remarkably increased magnetic field intensity, several interesti…
