Porphyrin-Based Dye-Sensitized Solar Cells (DSSCs): a Review
(Springer/Plenum Publishers, 2017)
The current review aims to collect short information about photovoltaic performance and structure of porphyrin-based sensitizers used in dye-sensitized solar cells (DSSC). Sensitizer is the key component of the DSSC device. ...
Dielectric properties of lithium-perchlorate-filled acrylonitrile-hexyl methacrylate copolymer films
(Wiley, 2017)
A series of poly(acrylonitrile-co-hexyl methacrylate), PAN-co-PHMA, copolymers with various hexyl methacrylate (HMA) contents were synthesized by emulsion technique. The incorporation of HMA units into the copolymers was ...
Effect of particle size of mineral fillers on polymer-matrix composite shielding materials against ionizing electromagnetic radiation
(Springer, 2017)
Filler particle size is an important particle that effects radiation attenuation performance of a composite shielding material but the effects of it have not been exploited so far. In this study, two mineral (hematite-ilmenite) ...
Potassium compounds for gamma spectrometer efficiency verification
(Pergamon-Elsevier Science Ltd, 2017)
Now-a-days several standard and well calibrated radioactive sources are available for gamma spectrometer efficiency calibration but at some situations, like lack of standard calibrators, in need of verification of standards ...
A rapid synthesis of 2-substituted 1,2,3-triazole-1-oxide derivative starting from 4-(methyl)isonitrosoacetophenone and its Ni(II) complex: Characterization, DNA binding and cleavage properties
(Elsevier Science Bv, 2017)
An efficient route, not including any metal salt as a catalyst, for the synthesis of a new 2-substituted 1,2,3- triazole-1-oxide is reported in this paper. The title compound has been synthesized via reacting 4-(methyl)i ...
One-pot synthesis of a new 2-substituted 1,2,3-triazole 1-oxide derivative from dipyridyl ketone and isonitrosoacetophenone hydrazone: Nickel(II) complex, DNA binding and cleavage properties
(Academic Press Inc Elsevier Science, 2017)
An efficient and simple one-pot synthesis of a new 1,2,3-triazole-1-oxide via reaction between isonitrosoacetophenone hydrazone and dipyridyl ketone in the EtOH/AcOH at room temperature has been developed smoothly in high ...
The effect of process variables on the properties of nanoporous silica aerogels: an approach to prepare silica aerogels from biosilica
(Springer, 2017)
Silica aerogel, a nanoporous material, was produced by using rice husk ash via sol-gel method. The aim of the study is to examine effects of the acid type (acetic, hydrochloric, nitric, oxalic and sulfuric acid), dryer ...
Mercury determination in muscle tissue of fish samples using microwave digestion and CVAAS analysis
(Perkin - Elmer Corp., 2017)
In this study, the mercury (Hg) levels in muscle tissue of 19 different fish species were determined. The fish samples were collected from the Sakarya River, Sakarya Cark Stream, Sapanca Lake and the Western Black Sea, ...
Effects of some hormones on enzyme activities of carbonic anhydrase from brain in vitro
(Chemical Publishing Co., 2017)
Hormones are 3 classes as steroid hormones, peptide and proteohormones and derived hormones from amino acids. The influence of PTH, E2, T3, T4, TSH and cortizole hormones has been investigated on bovine brain carbonic ...
Expression of Cytosolic and Non-Cytosolic Carbonic Anhydrase Enzymes from Bovine Large Intestine
(Chemical Publishing Co., 2017)
Carbonic anhydrase is an enzyme that takes responsibility in inhalation function but, until today, carbonic anhydrase is not examined if it is present in the bovine large intestine or not. The enzyme carbonic anhydrase was ...
