Pesticide effect on kinetic properties of catalase enzyme
(Hitit Üniversitesi, 2017)
Catalase is a metalloenzyme. Contains Cu(II) as the metal ion. It is a detoxification agent for the H2O2 compound and protects tissues and cells from oxidative damage [1]. Cryogels are synthetic materials generally used ...
Synthesis and characterization of silicon carbide powders converted from metakaolin-based geopolymer
(Blackwell Publishing Inc., 2016)
Silicon carbide (SiC) ceramic powders were synthesized by carbothermal reduction in specific geopolymers containing carbon nanopowders. Geopolymers containing carbon and having a composition M2O·Al2O3·4.5SiO2·12H2O+18C, ...
Synthesis, characterization and electrochemical performance of Nb doped LiFePO4/C cathodes by mechanochemical activation
(Hitit University, 2018)
We synthesized Nb-doped LiFePO4/C nano composite cathode materials by mechanochemical activation followed by a single step calcination. The starting chemicals of Li2CO3, FeC2O4.2H2O, NH4H2.PO4 and C6H8O7 as lithium, iron, ...
Structural, electronic, and electrochemical analyses of sputter-coated Pt and Pt–Co/GCE electrodes with ultra-low metal loadings for PEM fuel cell applications
(Springer Netherlands, 2017)
In this study, unsupported platinum and platinum–cobalt ultra-thin catalyst layers with varying metal loadings were prepared by a sequential magnetron sputtering technique. The deposited catalyst layers were characterized ...
Electrochemical copper (II) sensor based on chitosan covered gold nanoparticles
(Kluwer Academic Publishers, 2014)
This study outlines a new sensing platform based on glassy carbon electrodes modified by gold nanoparticles (AuNPs) for the determination of heavy metal. A glassy carbon electrode was modified by chitosan stabilized AuNPs. ...
Acoustic analysis of a liquefied petroleum gas-fired pulse combustor
(2008)
Experimental investigation of acoustic characteristics of a Helmholtz type liquefied petroleum gas-fired pulse combustor is presented. In the experiments, the length of the tail pipe was changed from 1.9 m to 1.3 m by 10 ...
Atom-economical synthesis of complex heterocycles with N-O moiety
(Wiley Blackwell, 2015)
A concise and facile method for the synthesis of heterocyclic compounds with N-O tether was introduced. The two important steps of the synthesis are a Mitsunobu reaction and C-H activation. The Mitsunobu protocol allows ...
Effect of electrolytic nickel coating on fatigue life of iron based powder metal parts
(2011)
Electrolytic coating is one of the methods mainly used to provide corrosion resistance for the powder metal parts. The coatings have strong effects on mechanical properties of coated parts as well as on surface properties. ...
Biological strategies to counteract the effects of mycotoxins
(International Association for Food Protection, 2009)
Mycotoxins are fungal secondary metabolites that if ingested can cause a variety of adverse effects on both humans and animals, ranging from allergic responses to death. Therefore, exposure to mycotoxins should be minimized. ...
Residual stress analysis and expansion of plastic zone in simple supported woven Ni-Cr reinforced thermoplastic matrix composite laminated plates
(2006)
In this study, a residual stress analysis is carried out on symmetric and antisymmetric cross-ply and angleply thermoplastic simple supported laminated plates for transverse loading. Low density polyethylene thermoplastic ...
