Determination of Antioxidant Activities of Different Urginea maritima (L.) Baker Plant Extracts
(Jihad Daneshgahi, 2010)
The subject handled in this study is the determination of antioxidant activities of extracts obtained from the Urginea maritima (L.) Baker plant's leaves and tubers. Extractions which were obtained using various solvents ...
Biodiesel production from waste frying oils and its quality control
(Pergamon-Elsevier Science Ltd, 2010)
The use of biodiesel as fuel from alternative sources has increased considerably over recent years, affording numerous environmental benefits. Biodiesel an alternative fuel for diesel engines is produced from renewable ...
5-(3,6-Dibromo-9H-carbazol-9-yl)pentanenitrile
(Wiley-Blackwell, 2011)
In the title compound, C17H14Br2N2, the carbazole skeleton is nearly planar [maximum deviation = 0.055 (2) angstrom]. In the crystal, aromatic pi-pi stacking is observed between parallel carbazole ring systems of adjacent ...
A Comparative Study of Redox Parameters and Electrochemical Impedance Spectroscopy of Polycarbazole Derivatives on Carbon Fiber Microelectrode
(Korean Fiber Soc, 2010)
In this study, N-Carbazole and its derivatives (N-Vinylcarbazole, N-Ethylcarbazole, N-Vinylbenzylcarbazole, and N-Benzylcarbazole) were electrochemically polymerized on carbon fiber microelectrodes (diameter similar to 7 ...
9-Benzyl-9H-carbazole
(Wiley-Blackwell, 2010)
The asymmetric unit of the title compound, C(19)H(15)N, contains two crystallographically independent molecules. In both molecules, the planar carbazole moieties [maximum deviations = 0.037 (4) and 0.042 (3) angstrom] are ...

A Biosensor Based on Zucchini (Cucurbita Pepo L.) Homogenate as a Biorecognition Layer for Ascorbic Acid Determination
(Informa Healthcare, 2010)
An amperometric biosensor based on zucchini (Cucurbita pepo) tissue homogenate is presented. The zucchini tissue homogenate was crosslinked with gelatine using glutaraldehyde and fixed on a pretreated teflon membrane. The ...
A review study of (bio)sensor systems based on conducting polymers
(Elsevier Science Bv, 2013)
This review article concentrates on the electrochemical biosensor systems with conducting polymers. The area of electro-active polymers confined to different electrode surfaces has attracted great attention. Polymer modified ...
Synthesis and biological evaluation of 2,5-di(7-indolyl)-1,3, 4-oxadiazoles, and 2-and 7-indolyl 2-(1,3,4-thiadiazolyl)ketones as antimicrobials
(Pergamon-Elsevier Science Ltd, 2014)
A range of novel hydrazine bridged bis-indoles was prepared from readily available indole-7-glyoxyloylchlorides and 7-trichloroacetylindoles and underwent cyclodehydration to produce 2,5-di(7-indolyl)-1,3,4-oxadiazoles and ...
Detection of Parathyroid Hormone Using an Electrochemical Impedance Biosensor Based on PAMAM Dendrimers
(Wiley, 2015)
This paper presents a novel hormone-based impedimetric biosensor to determine parathyroid hormone (PTH) level in serum for diagnosis and monitoring treatment of hyperparathyroidism, hypoparathyroidism and thyroid cancer. ...
