Electrodeposited poly( o -toluidine) (POT) on gold electrodes was investigated in a 0.5 M H 2 SO 4 aqueous solution using cyclic electrogravimetry with in situ vis–NIR spectroscopy. This coupling of different techniques allows the electrical, color, and mass changes during the electrochemical reactions of these polyme…
Electrodeposited poly( o -toluidine) (POT) on gold electrodes was investigated in 0.5 M H 2 SO 4 aqueous solutions using alternating current electrogravimetry (simultaneous electrochemical impedance and mass transfer functions). The kinetic aspects of the three different redox transitions proposed for this polymer (le…
Abstract The influences of styrene–butadiene–styrene (SBS) copolymer compatibilizer and compounding process on the electrical conduction and thermal stabilities of carbon black (CB)‐filled immiscible polypropylene (PP)/polystyrene (PS) (1/1) blends were investigated. The immiscible CB/PP/PS composite with CB homogeneo…
Free-standing porous silica microstructures have been made via the electroassisted deposition of silica in an appropriately patterned array of recessed electrodes consisting of hydrophilic and hydrophobic domains. The 100 nm deep recessed indium tin oxide (ITO) electrodes were prepared by a photolithographic/chemical…
This study investigates how the acid treatment of multi-walled carbon nanotubes affects the fatigue behavior of carbon nanotube/epoxy composites. Nanocomposites with 0.5 and 1.0 wt% acid-treated carbon nanotubes display slightly and significantly stronger fatigue strength than those with equal-content as-received carb…
We describe herein the synthesis of a triptycene-based surfactant designed with the ability to solubilise single-walled carbon nanotubes (SWNTs) and C(60) in water through non-covalent interactions. Furthermore, an amphiphilic naphthalene-based surfactant with the same ability to solubilise SWNTs and C(60) has also be…
Polymerisierbare und hydrolytisch spaltbare Derivate von Dexamethason (DEX, roter Punkt) wurden kovalent in kernverknüpften Polymer-Micellen bestehend aus einem temperaturempfindlichen Blockcopolymer (gelber und grauer Baustein) eingeschlossen. Die Freisetzungsrate konnte über den Oxidationsgrad des Thioethers im Link…
This paper reports on the corrosion of Mg alloy AZ31 in simulated body fluid (SBF) using static immersion tests and electrochemical impedance spectroscopy. A preliminary study on the effect of flowing SBF on the corrosion behaviour of AZ31 has also been carried out. Low toxicity ionic liquids (ILs) trimethyl(butyl)pho…
Abstract Chitosan (CS) grafted poly[(acrylic acid)‐ co ‐(2‐hydroxyethyl methacrylate)] (CS‐ g ‐poly(AA‐ co ‐HEMA)) at different molar ratios of AA and HEMA, and the associated nanocomposite hydrogels of CS‐ g ‐poly(AA‐ co ‐HEMA)/mica were synthesized by radical copolymerization. The grafting positions at the amino or…
Abstract High strength Al nanostructured materials have attracted increasing attention for weight critical and high reliability completion tools applications in the oil and gas industry. The novel nanostructured materials have demonstrated ultrahigh specific strength (i.e. ∼3 times of steel), enhanced specific stiffne…
Abstract Today, we stand at the threshold of exploring carbon nanotube (CNT) based conducting polymer nanocomposites as a new paradigm for the next generation multifunctional materials. However, irrespective of the reported methods of composite preparation, the use of CNTs in most polymer matrices to date has been lim…
Abstract In this work, thermogravimetric data were used for to study the thermal degradation of corn starch with and without thermo‐alkaline treatment. Flynn–Wall–Ozawa, modified Coats–Redfern, and Kissinger methods were used to determine the activation energy. Corn starch treated with calcium hydroxide exhibited the…

Summary The antibacterial activity of zinc oxide nanoparticles prepared by sonication method was evaluated in this paper. Effect of calcination conditions on the size and antibacterial activity of zinc oxide nanoparticles was investigated. Zinc oxide nanoparticles were characterised for purity (Thermo Gravimetric Anal…
The use of fillers tends to reduce paper strength, which can limit their application. Therefore research on filler modification is of significant importance in order to overcome this limitation. In this paper, precipitated calcium carbonate (PCC) was modified by starch, sodium stearate, and the starch cross-linking ag…
Abstract The goal of this study was to develop doxorubicin conjugate nanoparticles with increased antitumor effects, reduced side effects and the ability to overcome multidrug resistance (MDR). In this regard, folate‐decorated maleilated pullulan–doxorubicin conjugate nanoparticles were developed as carriers for co‐de…
BACKGROUND: There is an urgent need for the discovery of new anti-malarial drugs. Thus, it is essential to explore different potential new targets that are unique to the parasite or that are required for its viability in order to develop new interventions for treating the disease. Plasmodium serine hydroxymethyltransf…
Abstract Gold nanoparticle embedded polyaniline (PANI) was synthesized by in situ oxidative polymerization of monomer aniline. X‐ray diffraction and Fourier transform IR techniques were used to establish the structure of the gold–PANI composite. UV–visible absorption studies have shown that, along with the normal abso…
Abstract The purpose of this study was to investigate the effects of polyol on glycidyl azide polyol (GAP)‐based energetic thermoplastic polyurethane elastomers (ETPEs). Briefly, a series of GAP/polyol‐based ETPEs (GAP/polyol ETPEs) with different copolyol ratios and hard segment contents were synthesized using GAP‐di…
We present a direct numerical simulation method for investigating the dynamics of dispersed particles in a compressible solvent fluid. The validity of the simulation is examined by calculating the velocity relaxation of an impulsively forced spherical particle with a known analytical solution. The simulation also give…
