This study aims to explore an effective route for the preparation of conductive N-substituted polyaniline (PANI) by the incorporation of brominated poly(styrene-co-p-methylstyrene) onto the emeraldine form of polyaniline. For this purpose, at first, poly(styrene-co-p-methylstyrene) was synthesized via nitroxide-mediat…
The toxic effects of synthetic corrosion inhibitors have led to the search for naturally occurring substances which are not only readily available but are also environmentally friendly. Therefore, this study investigates the inhibition efficacy of acid extract of Nicotiana tabacum leaves on mild steel in 1M HCl using…
A novel biological approach for the rapid and cost effective synthesis of silver nanoparticles was attempted in the limelight of nanotechnology research. The present study demonstrates the synthesis of silver nanoparticle using fungus Aspergillus terreus CZR-1 (NCBI GenBank Accession No. JF 681300). The fungal isolate…
Hydrophobic organic-inorganic hybrid monolithic columns were synthesized via thermally initiated free radical polymerization with the confines of 75 μm id capillary using a polyhedral oligomeric silsesquioxane (POSS) reagent containing eight or more methacrylate groups as the crosslinker. Three organic functional mono…
By using non-equilibrium Green’s functions in combination with the density-functional theory, we investigate the spin transport properties of molecular junctions based on 3d transition terminated zigzag graphene nanoribbons. The results show that the electronic transport properties are strongly depending on the type o…
One of the main problems in using vegetable fibers as reinforcement in aggressive cement matrix is the penetration of alkaline products in the porous structure of the filaments, making them very fragile with the time. In this sense a series of physical and chemical methods of surface modification has been used in orde…
Abstract High molecular weight polyaniline (PANI) was synthesized by a combined procedure incorporating various synthesis methods. Temperature and open circuit potential of the reaction mixture were collected to monitor the reaction progress. The polymer is characterized by various techniques including gel permeation…
The non-linear dynamic thermomechanical behaviour of superelastic shape memory alloys is investigated. To this end, the Zaki–Moumni model, initially developed for quasi-static loading cases, is extended to simulate the uniaxial forced oscillations of a shape memory alloy device. First, the influence of loading rate is…
Chemical doping is an effective method to intrinsically modify the chemical and electronic property of graphene. We propose a novel approach to synthesize the nitrogen-doped graphene via thermal annealing graphene with urea, in which the nitrogen source can be controllably released from the urea by varying the anneale…
Thermoresponsive polymer surface coatings are a promising tool for cell culture applications. They allow for a mild way of cell detachment that preserves the activity of membrane proteins-a prerequisite for reliable cell analysis. To enlarge the application range of these coatings to cells with different adhesion prop…
We present density functional theory (DFT) calculations with periodic boundary conditions combined with thermodynamic and kinetic analyses to study the changes in the [Mg 2/3 Al 1/3 (OH) 2 ](CO 3 ) 1/6 ·2/3H 2 O layered double hydroxide (LDH) over a temperature interval of 25–350 °C. The inspection of five different h…
Despite the large interest in the application of LaBr3:Ce3+, little is known yet about its optical properties, as measurements are hampered by the hygroscopicity of LaBr3:Ce3+and because it is not trivial to produce crystals with optically polished surfaces. Here, the absorption and scattering lengths as well as the r…
Abstract Crystalline, mesoporous alumina (Al 2 O 3 ) materials with specific surface areas up to 400 m 2 g –1 have been synthesized by means of structure replication (nanocasting) using CMK‐8 carbon as a structure matrix. A crucial step during this synthesis procedure is the conversion of aluminum nitrate into aluminu…
In order to explore a method for assessing the aging characteristics of composite insulators, the composite insulators in service were studied using the Fourier Transform Infra-Red (FTIR) test. The influences of several aging factors on the shed materials of composite insulators in service such as shed locations, oper…
We fabricated thin-film thermoelectric modules for thermal–photovoltaic hybrid solar generator. Bi 0.5 Sb 1.5 Te 3 (p-type) and Bi 2 Te 2.7 Se 0.3 (n-type) thermoelectric thin films were deposited by radio-frequency magnetron sputtering method and patterned to form plane-type thermoelectric modules using lift-off tech…
This paper explores a means of quantifying the relationship between transient earth voltage (TEV), ultra-high-frequency (UHF) and IEC60270 partial discharge (PD) measurements on a pulse-by-pulse basis for well-defined, laboratory-based discharge sources. Since each technique responds differently to the same PD event,…
Site-specific on-demand cooling of hot spots in microprocessors can reduce peak temperature and achieve a more uniform thermal profile on chip, thereby improve chip performance and increase the processor’s life time. An array of thermoelectric coolers (TECs) integrated inside an electronic package has the potential to…

The present work deals with the synthesis and characterization of CdS nanoparticles with good thermal stability and optical properties by a novel and simple synthetic route. The nanoparticles were synthesized via chemical precipitation method in a single reaction vessel under ambient conditions. The prepared CdS nanop…
The extracellular cellulase enzyme produced by Trichoderma reesei was used to prepare Nanocrystalline Cellulose (NCC) by controlled hydrolysis of bamboo fibers. The morphology of the prepared bamboo cellulose nanocrystals was characterized by field emission scanning electron microscopy and the crystallinity was measur…
