Evaluation Of Antioxidant Activity Of Crataegus Species Collected From Different Regions Of Turkey
(Acg Publications, 2012)
Crataegus species (Rosaceae), known as "Howthorn" have found special medicinal use for the treatment of mild heart diseases. This work aims to measure the antioxidant capacities of various Crataegus species growing in ...
Immobilized Metal Ion Affinity Nanospheres For Alpha-Amylase Immobilization
(Scientific Technical Research Council Turkey-Tubitak, 2014)
Immobilized metal chelate affinity chromatography (IMAC) support was practiced for alpha-amylase immobilization. Poly(hydroxyethylmethacrylate-methacryloylamidotryptophan)-Ni2+ [p(HEMA-MAT)-Ni2+] nanospheres, average ...
Ionizing Radiation: A Versatile Tool For Nanostructuring Of Polymers
(Walter De Gruyter Gmbh, 2016)
Very high energies of particulate (accelerated electrons, swift heavy ions) or electromagnetic wave (gamma-, X-rays) radiation can be used to initiate free radical based reactions in solids, liquids or gases. Because of ...
A Rare Gamma-Pyranopyrazole Skeleton: Design, One-Pot Synthesis And Computational Study
(Royal Soc Chemistry, 2016)
Drawing upon a consecutive amide coupling and intramolecular cyclisation pathway, a one-pot, straight-forward synthetic route has been developed for a range of pyrazole fused gamma-pyrone derivatives. The reaction mechanism ...
Facile Synthesis Of Heteroaryl Substituted Gamma-Lactams From Nitrovinyl Arenes
(Scientific Technical Research Council Turkey-Tubitak, 2018)
Aliphatic nitroalkanes with different functional groups were synthesized from the Michael addition reactions of active methylene compounds 2 and nitrovinyl arenes 1 in high yields. The synthesized Michael adducts were ...
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 ...
Caffeine Degradation In Water By Gamma Irradiation, Zonation And Zonation/Gamma Irradiation
(Inst Nuclear Chemistry Technology, 2014)
Aqueous solutions of caffeine were treated with ozone and gamma irradiation. The amounts of remaining caffeine were determined after solid phase extraction as a function of absorbed dose and ozonation time. In addition to ...
Chemical Synthesis Of Thiophene-Pyrrole Copolymer
(Slovensko Kemijsko Drustvo, 2003)
Oligomerization reactions of thiophene and pyrrole monomers and chemical copolymerization of these oligomers were investigated in acetonitrile solutions containing thiophene-HBF4, pyrrole-HBF4 and thiophene-pyrrole-HBF4. ...
Development Of An Amperometric Enzyme Electrode Based On Poly(O-Phenylenediamine) For The Determination Of Total Cholesterol In Serum
(Soc Brasileira Quimica, 2012)
A polymer-based amperometric enzyme electrode (Pt/PoPD/ChOx) was prepared for the amperometric detection of free cholesterol. Firstly, poly(o-phenylenediamine) (PoPD) polymer film was prepared in acetonitrile-water medium ...
Effect Of Sonic Treatment On The Permeation Performance Of Cellulose Acetate Membranes Modified By N-Sio2
(Scientific Technical Research Council Turkey-Tubitak, 2015)
Cellulose acetate (CA) membranes were modified by nano-silicon dioxide (n-SiO2), and they were exposed to ultrasonic waves at a frequency of 35 kHz. The effect of sonication on their water sorption tendency and permeation ...
