The unconventional solvent-limited synthesis approach for conductive polymer production is analyzed for the well-known system of HCl-doped polyaniline (PAN) to elucidate the impact of nearly solvent-free reactions on chemical and electronic structures including chain conformation, specifically, branching and cross-lin…
The study investigates the properties of lightweight (350-550 kg/m 3 ) particleboards made using wood or rape particles and with veneers applied to their surfaces. Their suitability for the production of furniture and elements of interior design is discussed. Panels with veneer on their faces were made using a "one sh…
Abstract Due to its excellent biocompatibility, Chitosan is a very promising material for degradable products in biomedical applications. The development of pure chitosan microfibre yarn with defined size and directional alignment has always remained a critical research objective. Only fibres of consistent quality can…
Manipulating the ferromagnetic interactions in diluted magnetic semiconductor quantum dots (DMSQDs) is a central theme to the development of next-generation spin-based information technologies, but this remains a great challenge because of the intrinsic antiferromagnetic coupling between impurity ions therein. Here, w…
Ultrafine Au particles incorporating TiO2 heterodimers were synthesized using an ambient heterogeneous spark discharge and the resultant materials were employed both in oxidizing photocatalytically CO gas and killing photothermally cancerous cells. Ti-Au spark configuration was employed to vaporize Ti and Au component…
The present study reports the synthesis of silver nanoparticle using Morus nigra leaf extract were used as reducing agent for reduction of silver nitrate solution. The synthesis of silver nanoparticles was analyzed by UV-Visible spectroscopy, Scanning Electron Microscopy. The SEM analysis has shown that size of silver…
Inflammation-induced activation of endothelium constitutes one of the earliest changes during atherogenesis. New imaging techniques that allow detecting activated endothelial cells can improve the identification of persons at high cardiovascular risk in early stages. Quantum dots (QDs) have attractive optical properti…
Silicon surface structures with excellent antireflection property arouse wide interest. Chemical and physical methods such as femtosecond, nanosecond, and picosecond laser processing, wet-chemical etching, electrochemical etching, and reactive ion etching have been developed to fabricate them. However, the methods can…
This paper describes a modified synthesis of NaB3H8 by the reduction of BH3·THF with sodium dispersed on silica gel. Single crystals obtained from CH2Cl2 show conclusively that the space group is Pmn21, in contrast to the Pmmn space group previously deduced from powder diffraction data.
Epiphytic diatoms on Nymphaea alba L. floating leaves during plant growing seasons in the oligotrophic Sub-Mediterranean wetland Hutovo Blato, South Bosnia and Herzegovina, were investigated in 2003 and 2004.In total, 135 taxa (species and infraspecific taxa) of epiphytic diatoms were identified.Genera with the larges…
Biobased ω-hydroxytetradecanoic acid prepared via an efficient yeast-catalyzed ω-hydroxylation reaction was converted by a one-step reaction to the polymerizable surfactants ω-acryltetradecanoic acid (MA-1) and ω-maleate tetradecanoic acid (MA-2). MA-1 is a single polar-headed surfactant, whereas MA-2 is a bolaamphiph…
In this paper, a numerical study of coupled heat and hydrogen transfer characteristics in an annular cylindrical hydrogen storage reactor filled with Mg2Ni is presented. An unsteady, two-dimensional (2-D) mathematical model of a metal hydride reaction bed of cylindrical configuration is developed for predicting the hy…
ABSTRACT This study investigates the structural, morphological, thermal, and mechanical properties of type A gelatin/montmorillonite (MMT) films as a function of MMT concentration. The variations of the X‐ray diffraction pattern suggest that the structure of the nanocomposites turns from intercalated to exfoliated on…
The aerosol deposition method (ADM) is a technique to form dense films by impacting solid particles on a substrate. Dense ceramic films with thicknesses of over several µm can be formed directly on substrates even at room temperature by the ADM. In this study, to improve the deposition efficiency of the ADM, the effec…
ABSTRACT Silicone pressure‐sensitive adhesives compositions contain a polydimethylsiloxane and a silicone resin, which can enhance the instant bonding ability and bonding strength of the adhesive. In this study, silicone resin was designed to have a low molecular weight and a highly nonpolar chemical structure. The si…
In the past few decades, nanoparticles have emerged as a field in biomedical research. Four isolated Aspergillus species were tested for extracellular synthesis of silver nanoparticles using their cell free filtrate (CFF). Silver nanoparticles of the most potent producer, Aspergillus terreus, were further characterize…
Label-free and low-cost surface-enhanced Raman scattering-active substrates of silver nanostructures on porous silicon have been synthesized. The morphology and spectroscopic properties were investigated as a function of concentration and immersion time. The enhancement factor of optimized silver-porous silicon substr…
We report the synthesis and structural characterization of a main-chain liquid crystal polymer constituted by a 1,2,4-oxadiazole-based bent-core repeat unit. For the first time, a liquid crystal polymer made of bent mesogenic units is demonstrated to exhibit cybotactic order in the nematic phase. Coupled with the chai…
ABSTRACT Blends of chlorinated polyethylene (CPE) elastomer and ethylene methacrylate copolymer (EMA) in various compositions were studied for their compatibility using differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and Fourier transform infrared (FTIR) spectroscopy techniques. Irrespectiv…
Bulk heterojunction (BHJ) solar cells have made great progress over the past decade and consequently are now attracting extensive academic and commercial interest because of their potential advantages: lightweight, flexible, low cost, and high-throughput production. Polymer conductivity is a key factor for improving t…
