By using free radical polymerization of (N-methacryloyloxyethyl-N?-4-picolyl)-urea (MAcPU) and N-acryloyl-L-leucine (AcLeu), an optically active copolymer, poly[(N-methacryloyloxyethyl-N?-4-picolyl)-urea-co-N-acryloyl-L-leucine], MAcPU-co-AcLeu (1.86:1 molar ratio) was prepared and subsequently functionalized at the p…
Conventional bamboo processing is performed with concentrated alkali. Mild treatments can be done with enzymes or microbes, with considerable environmental benefits. However, the existing commercial enzymes have limited effects on bamboo fibres. Here, we focus our study on a xylanase from Streptomyces sp. FA1, which w…
In this study, a buckypaper (BP), a foil of carbon nanotubes, with covalently bonded graphene leaves is prepared as a scaffold of pseudocapacitors. The capacitive electrodes are fabricated by an in situ growth of graphene on BP followed by electrochemical deposition of MnO2. The specific capacitance, energy/power-dens…
Photoluminescence, thermally stimulated luminescence and electron spin resonance are studied for a PbWO4 crystal grown by the Czochralski method at Bogoroditsk Technical Chemical Plant, Russia from the melt with a precise tuning of the stoichiometry and co-doped with La3+, Y3+, and Mo6+ ions. Photo-thermally stimulate…
ABSTRACT A high‐performance polymer polyethersulfone (CN‐Azo‐PES), with a flexible ethoxyl linkage between the azobenzene chromophore side chain and the PES backbone, has been designed and successfully synthesized for an application in a WORM type memory device as an active polymer layer. CN‐Azo‐PES has excellent ther…
The properties of field-effect transistors (FETs) with single crystals of Bi compounds, Bi2CuO4 and LaOBiS2, are investigated using an electric-double-layer capacitor. The observation of FET characteristics due to electrostatic carrier accumulation is very significant for the field-induced control of physical properti…
The technique to fabricate nanostructures with high resolution is of crucial importance to nanosciences and nanotechnology. This paper presented a nonconventional method to fabricate metallic nanobowl arrays via the conglutination process, which relied on the high adhesive material to “stick” nanostructures. The ultra…
Calcium molybdate CaMoO 4 crystals are perspective materials for many applications in acoustic‐electronics, acoustic‐optics and nonlinear optics. They are also used as laser hosts, scintillators, different kinds of substrates and active elements of ionizing radiation detectors. For all these applications large‐sized s…
A sustainable clean energy production from oxidation of biodegradable materials was carried out in a microbial fuel cell (MFC) stack consisting of four MFC units. The stack was fabricated and tested for its scalability using a high engineering, low oxygen mass transfer membrane; namely, sulfonated poly ether ether ket…
The aim of this study was to prepare and characterize biodegradable scaffolds of poly(lactic‐co‐glycolic acid) (PLGA 85:15) and nano‐hydroxyapatite (HA) containing magnesium carbonate (MC) as acidic microclimate controlling additive. Porous and nonporous scaffolds of PLGA 85:15 and nano‐HA containing MC were prepared…
Using density functional theory-based calculation, we have investigated the structural and electrical properties such as atomic structure, energetics, band gap, and work function of various armchair and zigzag CdS nanoribbons. Our study establishes that the armchair nanoribbons are more favorable compared to zigzag na…
Nano‐silica particles activated with different lanthanide triflates (cerium, lanthanum and yttrium) as fillers in silane sol‐gel coatings were investigated for higher corrosion protection of low carbon steel. Sol‐gel films have been synthesized from cross‐condensation of 3‐glycidoxy‐propyl‐trimethoxy‐silane (3‐GPTMS)…
Wurtzite CuInS2 nanoleaves were synthesized by Cu1.94S-assisted growth. By observing the evolution of structures and phases during the growth process, Cu1.94S nanocrystals were found to be formed after uninterrupted oxidation and sulfidation of copper nanoparticles at the early stage, serving as catalysts to introduce…
In environmental scanning electron microscopy (ESEM) high pressure applications have become increasingly important. Wet or biological samples can be investigated without time-consuming sample preparation and potential artefacts from this preparation can be neglected. Unfortunately, the signal-to-noise ratio strongly d…
Bleached bamboo fiber was treated with a high pressure enzymatic hydrolysis (HPEH) process in order to produce microfibrillated bamboo fiber (MBF). Mixture design of experiments was utilized to determine the optimal constituents of fiber, enzymes, and water for the HPEH process on the isolation yield of the MBF. Resul…
Materials Science represents the natural convergence of hard scientific disciplines such as Physics Mathematics and Chemistry whom synergic contribution to its definition and evolution is at the basis of huge technologic development observed during the last few decades. The wide variety of materials under investigatio…
Abstract A sensitive dopamine sensor was constructed based on the modified carbon paste electrode with methylthiouracil as a nucleophile in the 1,4‐Michael addition reaction. An ECE mechanism was suggested for dopamine oxidation at the modified electrode. Design of experiments was used in the optimization of variables…
With increasing miniaturization, it is extremely important to maintain the magnetization stability at small scale. Herein, more efforts and interests focus on the interface of magnetic core and semiconductor shell to obtain desired magnetic and/or luminescent properties.

OBJECTIVE: We aimed to investigate the effectiveness and radiation protection capability of latex gloves coated with various contrast agents as an alternative to lead gloves. METHODS: The following six groups were created to evaluate the permeability of X-ray in this experimental study: lead gloves, two different non-…
Chromatography is a common step in the solution-phase synthesis of typical peptides, as well as peptide fragments for subsequent coupling on a solid support. Combining known reagents that form readily separable byproducts is shown to eliminate this step, which wastes time and other resources. Specifically, activating…
