Abstract The kinetic parameters of homogeneous nucleation of KCl in different ethanol‐water solvent mixtures were determined at 25°C from the experimental measurements of the width of the metastable zone at different cooling rates. The ethanol mass ratio in the ethanol water solvent mixture was varied from 0‐0.9 and t…
Abstract A new nonlinear optical material tetrakis thiourea nickel chloride (TTNC) was synthesized and single crystals were grown from mixed solvent of water and isopropanol by both slow evaporation and slow cooling methods. The grown crystals were characterized by powder X‐ray diffraction analyses to confirm the crys…
The addition of homopolymers to a self-assembling rod−coil block copolymer is demonstrated to be a flexible route toward domain size control. Molecular weight matched rod-like homopolymers interdigitate with the rod-blocks within their respective lamellae. As a result of the interdigitation, the coil blocks must rearr…
In this paper, we report on modification of the structural, optical, vibrational, and surface morphological properties of 2 MeV N(+)-ion irradiated WO(3) thin films at different fluences (up to 1 × 10(15) ions cm(-2)). Although we observe irradiation induced grain growth, no structural phase transition takes place in…
Deformation-induced modification of the dispersion state of silica nanoparticles in poly(ethylene terephthalate) (PET) has been characterized by means of transmission electron microscopy (TEM) and wide-angle X-ray diffraction (WAXD). We focused on the biaxial deformation applied at a temperature just above the glass t…
Carbon nanotubes (CNTs) have substantial promise as nanocontainers filled with fluid in their hollow cavity in nanotechnology. This paper reports the result of an investigation into the influence of internal fluid on the coupling vibration of fluid-filled CNTs. The coupling vibrational behaviour of fluid-filled CNTs u…
The adsorption-desorption phenomenon of neutral particles dissolved in an isotropic fluid is investigated by using a nonsingular kernel in the kinetic equation at the limiting surfaces. To account for the relevance of a memory effect, three types of kernels in the kinetic equation are considered. Similar kernels have…
This review deals with the role of electron-phonon (e-ph) coupling in quantum transport of carbon nanotubes. First, the case of low-energy phonons and weak localization phenomena is addressed, followed by a summary of inelastic scattering lengths within the Fermi golden rule. A second part outlines the contribution of…
Abstract Layer‐multiplying coextrusion was used to fabricate assemblies of 257 layers, in which polypropylene (PP) nanolayers alternated with thicker polystyrene (PS) layers. The PP layer thickness was varied from 12 to 200 nm. When the assembly was heated into the melt, interfacial instability‐driven breakup of the t…
Abstract Transition metal and lanthanide monoporphyrinate complexes based on 5,10,15,20‐tetrakis[ p ‐(diphenylamino)phenyl]‐21 H ,23 H ‐porphine (H 2 tdpapp) have been synthesized and characterized and the X‐ray crystal structures of the palladium and platinum analogues [M(tdpapp)] (M = Pd, Pt) determined. Experimenta…
Interfacing of ferroelectric and semiconductor materials provides a means of coupling unique properties associated with ferroelectric materials to high performance semiconductor devices. In this work we report the electronic properties of ferroelectric/ZnO heterostructures, where (Pb,Zr)TiO3 (PZT) is used as a prototy…
This paper presents a number of factors which have been found to be important to the growth of carbon nanotubes and nanofibres by plasma enhanced chemical vapour deposition. The effect of the electric field in a plasma discharge on nanotube growth is investigated and shown to be important in achieving nanotube alignme…
Plasma fabrication provides an approach to create nanostructured materials. We summarize recent studies on the quantum dot, nanograss, porous film and nanocone that have been developed using plasma methods to date and investigate the antireflection properties of the nanograss by spectrophotometric measurements and rig…
Traditionally, large quantities of ceramic fillers are added to polymers in order to obtain high thermally conductive polymer composites, which are used for electronic encapsulants. However, that is not cost effective enough. In this study, Si3N4 particle filled epoxy composite with a novel structure was fabricated by…
Low pressure silane plasmas are known for their ability to synthesize silicon nanoparticles via gas phase nucleation. While in the past this particle formation has often been considered from the viewpoint of a contamination problem in semiconductor processing, we here describe a silane low pressure plasma that enables…
Mg(NH 2 ) 2 −2LiH is considered a promising hydrogen storage composition because of its reversibility, moderate operating conditions, and favorable thermodynamics. Two barriers which remain for this system are reducing (eliminating) ammonia release which occurs in parallel with hydrogen desorption and further reducing…
The biocompatibility of diamond was investigated with a view toward correlating surface chemistry and topography with cellular adhesion and growth. The adhesion properties of normal human dermal fibroblast (NHDF) cells on microcrystalline and ultrananocrystalline diamond (UNCD) surfaces were measured using atomic forc…
Abstract The organic material 4‐Ethoxybenzaldehyde‐N‐methyl 4‐Stilbazolium Tosylate (EBST) is a new NLO material and new derivative in Stilbazolium Tosylate family. In this work we synthesized the EBST, the derivative of DAST. By slow evaporation method, we have grown the EBST crystal. Powder XRD confirms the crystall…

We report on the successful fabrication of arrays of switchable nanocapacitors made by harnessing the self-assembly of materials. The structures are composed of arrays of 20-40 nm diameter Pt nanowires, spaced 50-100 nm apart, electrodeposited through nanoporous alumina onto a thin film lower electrode on a silicon wa…
