Preparation and characterization of polyvinyl alcohol based copolymers as wound dressing fibers
(Taylor and Francis Inc., 2015)
Biocompatible polyvinyl alcohol/polyethylene glycol and polyvinyl alcohol/polypropylene glycol copolymer mats were prepared by electrospinning. The composite fiber mats were subjected to detailed physical analysis complemented ...
On the negative capacitance behavior in the forward bias of Au/n–4H–SiC (MS) and comparison between MS and Au/TiO2/n–4H–SiC (MIS) type diodes both in dark and under 200 W illumination intensity
(World Scientific Publishing Co. Pte Ltd, 2015)
In order to see the effect of interfacial layer on electrical characteristics both Au/n-4H- SiC (MS) and Au/TiO<inf>2</inf>/n-4H-SiC (MIS) type Schottky barrier diodes (SBDs) were fabricated and their main electrical ...
Theoretical prediction of the structural, elastic, mechanical and phonon properties of bismuth telluride under pressure
(World Scientific Publishing Co. Pte Ltd, 2015)
Bismuth telluride (Bi2Te3) is one of the most intricate materials with its semiconducting, insulating and pressure-induced superconducting properties. Although different theoretical works have been carried out to understand ...
Fe(II)-Co(II) double salt incorporated magnetic hydrophobic microparticles for invertase adsorption
(Humana Press Inc., 2015)
Invertase (β-fructofuranoside fructohydrolase, EC 3.2.1.26) is an enzyme widely used in the food industry. Its main function is the formation of glucose and fructose through hydrolysis of sucrose. For the separation and ...
Electrical properties and hyperfine interactions of boron doped Fe3O4 nanoparticles
(Academic Press, 2015)
The single spinel phase nano-structured particles of FeBxFe2-xO4 (x = 0.1, 0.2, 0.3, 0.4 and 0.5) were synthesized by the glycothermal method and the effect of B3+ substitution on structural and dielectric properties of ...
Intramolecular Gold-Catalyzed and NaH-Supported Cyclization Reactions of N-Propargyl Indole Derivatives with Pyrazole and Pyrrole Rings: Synthesis of Pyrazolodiazepinoindole, Pyrazolopyrazinoindole, and Pyrrolopyrazinoindole
(American Chemical Society, 2015)
Gold-catalyzed and NaH-supported intramolecular cyclization of N-propargyl indole derivatives with pyrazole and pyrrole units attached to indole is described. An efficient route to the synthesis of pyrazolodiazepinoindole, ...
Design of pyrazolo-pyrrolo-pyrazines and pyrazolo-pyrrolo-diazepines via AuCl3-catalyzed and NaH-supported cyclization of N -propargyl pyrazoles
(American Chemical Society, 2015)
A concise synthetic methodology for new heterocyclic scaffolds, such as pyrazolo-pyrrolo-pyrazine and pyrazolo-pyrrolo-diazepine skeletons, was developed. The key features of this method include (i) synthesis of pyrrole-derived ...
Frequency and voltage dependence of electric and dielectric properties of Au/TiO2/n-4H-SiC (metal-insulator-semiconductor) type Schottky barrier diodes
(Institute of Physics Publishing, 2015)
The main electrical and dielectric properties of Au/TiO2/n-4H-SiC (MIS) type Schottky barrier diodes (SBDs) have been investigated as functions of frequency and applied bias voltage. We believe that the use of high dielectric ...
Boric acid: A simple molecule of physiologic, therapeutic and prebiotic significance
(Walter de Gruyter GmbH, 2015)
Boric acid, H3BO3, is a weak acid and at physiological pH is in the form of an uncharged small molecule. Behaving as a Lewis acid, it forms complexes with amino- and hydroxy acids, carbohydrates, nucleotides and vitamins ...
CO2 gas detection properties of a TIO2/Al2O3 heterostructure under UV light irradiation
(Institute of Physics Publishing, 2015)
Al/TiO2/p-Si and Al/TIO2/Al2O3/p-Si samples were prepared using the atomic layer deposition method (ALD) and their gas sensing properties were investigated. The electrical properties of the samples were studied using a two ...
