Six copolyesters were prepared from bis(4-hydroxybenzylidene)acetone (HBAC) and bis(4-hydroxy-3- methoxybenzylidene)acetone (MBAC) (as varying diol, diol-1) with adipoyl chloride, azelaic acid dichloride and sebacoyl chloride and 4-(4-nitrophenylazo)resorcinol (as a common diol, diol-2) by phase transfer catalysed con…
There has been an increased usage of adjustable frequency drives (AFD) coupled with induction motors due to the demand for higher operating efficiency levels. Due to the starting requirements, motor manufacturers are forced to employ high resistivity rotor bars which lead to higher losses and lower motor efficiency. T…
Silk fibroin (SF) has been extensively studied for application in wound dressing, bone, vessel and nerve regeneration. We have previously reported on good in vitro biocompatibility of SF nanofibers with neuronal cell. In the present study, we prepared SF nanofiber-based artificial nerve conduit to bridge 10mm long sci…
The interaction of CdSe/ZnS nanocrystals (NCs) (solubilized by trioctylphosphine oxide (TOPO) molecules) with ortho-phenanthroline (OP) molecules has been investigated. It is shown that OP molecules can replace TOPO; in this case, bonding of OP molecules with the nanocrystal surface does not lead to the formation of N…
Abstract Atomistic quantum simulation is performed to compare the performance of zero-Schottky-barrier and doped source-drain contacts carbon nanotube field effect transistors (CNTFETs) with strain applied. The doped source-drain contact CNTFETs outperform the Schottky contact devices with and without strain applied.…
Abstract This paper presents the investigation of tuning the color and photoluminescence of a range of triphenylamine‐ based derivatives with various substituent groups. The ultraviolet/visible absorption and fluorescence spectroscopy of the derivatives showed remarkable difference. The molecular geometry optimization…
Low-frequency (LF) atmospheric-pressure plasma (APP) jets have been used for patterning of thin fibronectin films deposited on a silicon (Si) wafer with the use of a metal stencil mask. Since fibronectin is an adhesion protein that can be found in the extracellular matrix (ECM), a micro-patterned fibronectin film may…
In the last few years, an intense research effort has focused on the synthesis of fluorescent nanopigments for functional inks, light harvesting, tagging, tracing, (bio)labeling, imaging, and lighting applications. Moreover, combined with dielectric matrices, these fluorescent nanoparticles may open the way to the rea…
Zirconium oxide (ZrO 2 ) has generated wide interest because of its potential in applications such as solid oxide fuel cells, catalysts and optical devices. In these applications, it is important to control the grain size of the material and increase the surface area by introducing porosity with tailored pore size. Th…
Neodymium based magnets are the powerful permanent magnet of today. This paper will discuss iron based rare earth magnets. NdFeB sintered magnet material has been developed. The magnets are produced by powder metallurgy route involving hydrogen decrepitation technique for making fine powder. After melting and casting,…
Abstract The morphology of hydrotalcites determines their use in catalysis, biomedicine, or adsorption as they may work as anion exchangers or as drug deliverers. In catalysis, reagents need access to as much surface area as possible; in biomedicine, drugs have to be encapsulated. However, the parameters and the mecha…
We produce uniform macroporous double-layers on 6 inch n-type silicon substrates by electrochemical etching under rear side illumination in a hydrofluoric acid (HF)-based electrolyte. The etched area is circular with a diameter of 13 cm. We demonstrate the detachment of 20 μm thick free-standing macroporous silicon la…
The approach to determination of the thickness and the refractive indices of dielectric films obtained in searching experiments is discussed. Experiments of this kind often exhibit unpredictable values of thickness and refractive indices of films. Nondestructive noncontact methods of spectrophotometry and ellipsometry…
In order to make high performance wood-plastic composites (WPCs) from wood-fiber and mixed plastic wastes, virgin resins were compounded to simulate mixed plastic wastes, which included polypropylene, polyethylene and/or polystyrene, then grafted with maleic anhydride (MAH) by reactive extrusion. Highly filled WPCs we…
The existence of clusters in weakly doped lanthanum manganites at temperatures about twice as high as their Curie temperature T C has been shown. Electrical resistance in weakly doped lanthanum manganites obeys the Efros-Shklovskii law. The temperature and magnetic-field dependences of a cluster size determined from t…
This paper investigated the synthesis conditions of nano-sized TiO2 powder in a hydrothermal process at a temperature range of 100 similar to 180 degrees C considering the precipitation agent, precipitation pH, reaction temperature and time. Titanium hydroxide formed by NH4OH exhibited a lower crystallization temperat…
Elastic syntactic foam is a special kind of composite material. It consists of a silicone gel matrix (called binder) and hollow spherical particles with a diameter in the range of 20 - 200 μm (so called microspheres) which are mixed into the binder. This Material is very soft, elastic and features a high compressibili…
Following an experimental discovery of its extremely high thermal conductivity, graphene was proposed as material for heat removal. To evaluate the feasibility of graphene's use for thermal management we simulated heat propagation in siliconon- insulator (SOI) structures with and without graphene or few-layer graphene…
. Aqueous suspensions containing small magnetic particles have been increasingly used in biosciences and biotechnology. Magnetic particles develop magnetic polarization and magnetophoretic mobility, and because of such unique properties, these carriers may be eligible candidates for delivering drugs to specific sites…
Polyaniline (PANI) nanocomposites were synthesized by incorporating separately synthesized metal nanoparticles in 1-methyl-2-pyrrolidinone (NMP) solution of polyaniline. PANI was prepared by oxidative reduction of aniline using chemical method. Silver nanoparticles were produced by inert gas condensation; whereas gold…
