Abstract The cancer Nanotechnology Laboratory Web portal ("http://cananolab.nci.nih.gov/caNanoLab/welcome.do":http://cananolab.nci.nih.gov/caNanoLab/welcome.do) is designed to promote sharing of nanomedicine data and to provide support for the annotation of nanoparticles with information about their composition, funct…
This report intends to elicit information in relation to a research-based project carried out at National Physical Laboratory, New Delhi. As the work has been pursued in two broadly different areas so the report has been divided into two parts, Part-A on the Magnetic Materials and, Ferrites materials and their applica…
Polymer based organic photovoltaic (OPV) technology offers a relatively inexpensive option for solar energy conversion provided its efficiency increases beyond the current level (6-7%) along with significant improvements in operational lifetime. The critical aspect of such solar cells is the complex morphology of dist…
Polymer nanocomposites (PNCs) have gained significant interest because they have outstanding performance that allows cost reduction, weight reduction, and product improvement. This research study focuses on the manufacture and characterization of PNCs in order to explore their potential in automotive applications. Mor…
In this research work the PEG6000 be cast with metronidazole for the formation of solid dispersions, the antiparasitic drug is insoluble in water, which leads to problems of bioavailability in the body. Solid solutions were prepared with a ratio of 1:0.25, 1:0.50, 1:0.75 metronidazole: PEG6000 which generated three da…
Presented work deals with the evaluation of the connection between the shape of (nano)filler and the polystyrene (nano)composites. Fillers and nanofillers with various type of particles (spherical, tubes, layered...)were chosen for the preparation of PS composites and nanocomposites. All samples were prepared by the c…

Abstract In this contribution we present an easy and efficient method for the controlled synthesis of highly uniform silica coated coaxial carbon nanotubes (CNT). Furthermore, the thickness of silica wall, CNT, and the diameter of CNT could be controlled at will. This process involves the use of an anodized aluminum o…
We demonstrate high-performance low-temperature poly-Si thin film transistors (LTPS-TFTs) with a -based top-gate-stack and combine the channel film by laser annealing and glass substrate (glass substrate high-κ metal-gate thin film transistor, called GSHM-TFTs). The GSHM-TFTs of n-channel (called GSHM-NTFTs) exhibit a…
Abstract The qualitative structures of the upper one‐electron energy levels of imidazole‐coordinated first‐row transition metal porphyrin [MePIm 2 ] complexes established in the present study have shown that the second oxidation number of the first‐row transition metals in the neutral complexes do not change in their…
The low-frequency optical properties of CuS nanoparticles in the composite samples were measured by the terahertz time-domain spectroscopy. Then, the power absorption, refractive index, complex dielectric function and conductivity of pure CuS nanoparticles are extracted by applying Bruggeman effective medium theory. T…
A frequency tunable electromagnetic metamaterial is proposed based on mechanical movement method. Two rings are etched against each other on two separate substrates and the two substrates can be adjusted to move relatively. Thus, the resonant frequency can be modulated due to the changed coupling capacitance between t…
In this work, to investigate the feasibility of plasmonics for data storage, we studied several aspects of the plasmoincs in confining and enhancing the light field in subwavelength metallic structures. Starting from the brief review on the plasmonic resonance in simple metallic nano-structures such as metallic ellips…
Silk fibroin is gaining interest as a novel scaffold for regeneration. The fabrication of nanofibers using an electrospinning technique is one of the most promising means of fabricating for Tissue engineering. RGD (arg-gly-asp) sequence, a novel cell adhesion molecule, is a candidate for silk surface modification to i…
In this research, the effect of modified filler on mechanical properties of polymer/clay composite was studied. Firstly, the filler - vermiculite was modified by two methods. Former one was done by hexadecyltrimethylammonium bromide, the latter by maleic anhydride. The level of clay modification was determined by X-ra…
Funcionalization of the filler surface is very important factor for achieving good interaction between filler and polymer matrix. In addition the mechanical as well as chemical properties, thermal stability, gas permeability, and flammability can be substantially improved. Hence, the intercalation of kaolinite by urea…
In spite of the achievements, some aspects related to deformation, kinematics and dynamics of the rolling process still remain unsolved. As a result, sometimes, important practical solutions are given without sound scientific grounds. Moreover, some theoretical solutions need experimental confirmation; until now, the…
The feasibility and utility of a chromatographic approach for evaluating crystal growth modifiers were demonstrated. Relative binding affinities of impurity molecules on calcite and calcium oxalate monohydrate crystals were dependent upon the type and number of functional groups and their stereochemistry. Equilibrium…
The objective of this study was to prepare magnetic microspheres as a targeting drug delivery system and to specifically evaluate its targeting efficiency. The magnetic microspheres were prepared by emulsion cross-linking techniques. Targeting efficiency was specifically investigated by experiments of biodistribution…
