Production and characterization of liquid crystal/polyacrylonitrile nano-fibers by electrospinning method
(Springer Link, 2021)
We present that high birefringent nematic liquid crystal, 4-n-pentyl-4'-cyanobiphenyl, was incorporated into the polyacrylonitrile precursor which has a strong polar cyano group so as to produce electrospun nano-fibers, ...
GENETIC UNIFORMITY OF A SPECIFIC REGION IN SARS-CoV-2 GENOME AND REPURPOSING OF N-ACETYL-D-GLUCOSAMINE
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2021)
The causative agent of the viral pneumonia outbreak in the world identified as SARS-CoV-2 leads to a severe respiratory illness like SARS and MERS. The pathogen spreading has turned into a pandemic dissemination and increased ...
Inhibitory activities of medicinal mushrooms on ?-amylase and ?-glucosidase-enzymes related to type 2 diabetes
(Elsevier B.V., 2021)
Mushrooms have been used as a primary source of medicines since ancient times due to the presence of bioactive compounds. Enzyme inhibition is an important field of pharmaceutical research that provides insight into the ...
Electrochromic and electroluminescent devices based on a novel branched quasi-dendric fluorene-carbazole-2,5-bis(2-thienyl)-1H-pyrrole system
(Royal Soc Chemistry, 2011)
We report here the synthesis of a novel branched quasi-dendric system, 9,9'-(9,9'-dihexylfluorene-2,7-diyl)bis[3,6-bis(2,5-bis(2-thienyl) pyrrol-1-yl)carbazole], (FCSNS), in four steps, followed by coating onto an ITO-coated ...
Metal concentration of wild edible mushrooms in Soguksu National Park in Turkey
(Elsevier Sci Ltd, 2011)
Twelve varieties of fruiting bodies of wild edible mushrooms collected in 2002 from Soguksu National Park, Ankara, Turkey were analysed for Pb, Cd, Zn, Fe, Mn, Cu, Cr, Ni, and Co contents by inductively coupled plasma ...
Free-radical scavenging capacity and antimicrobial activity of wild edible mushroom from Turkey
(Academic Journals, 2006)
Antioxidant capacity and antimicrobial activities of Ramaria flava (Schaeff) Quel. (RF) extracts obtained with ethanol were investigated in this study. Four complementary test systems; namely DPPH free radical scavenging, ...
A Chebyshev Polynomial Approach for High-Order Linear Fredholm-Volterra Integro-Differential Equations
(Gazi Univ, 2012)
The purpose of this study is to present a method for solving high order linear Fredholm-Volterra integrodifferential equations in terms of Chebyshev polynomials under the mixed conditions. The method is based on the ...
A study on the humidity sensing properties of ZnCr2O4-K2CrO4 ionic conductive ceramic sensor
(Elsevier Science Sa, 2006)
The response to humidity of ZnCr2O4-K2CrO4 ceramic composites formed by solid-state reaction at elevated temperatures is studied. The fired ceramic body, which proved to be mainly constructed from ZnCr2O4 spinel grains, ...
Viscoelasticity, dielectric anisotropy, and birefringence in the nematic phase of three four-ring bent-core liquid crystals with an L-shaped molecular frame
(Royal Soc Chemistry, 2013)
Molecular shape is an important factor in determining the material properties of thermotropic liquid crystals (LCs). We synthesized and investigated several LC compounds formed by asymmetrically bent molecules with a rigid ...
Antioxidant and anticholinesterase active constituents from Micromeria cilicica by radical-scavenging activity-guided fractionation
(Elsevier Sci Ltd, 2011)
From the acetone extract of Micromeria cilicica, two new (1 and 2) and five known (3-7) compounds were obtained through radical-scavenging activity guided isolation. Structures of the compounds were identified as piperitone ...
