A good understanding about the properties of La/Nd doped Bismuth Titanate (BIT) ceramics at high temperature is very important as the new materials being developed based on the BIT. Pure BIT, La doped (BLT), Nd doped (BNT) and La and Nd co-doped BIT (BLNT) powders were synthesized by solid state reaction method. Prepa…
In situ polymerization of aniline was carried out in presence of nickel oxide (NiO) to synthesize polyaniline/nickel oxide (PANI/NiO) composites using chemical oxidation method. The method of synthesis is based on chemical oxidative polymerization of aniline doped with various wt % of nickel oxide by using ammonium pe…
The present study focused on the modification of the electrical and optical properties of polystyrene films with salt additive, namely, (n-butylammonium-oxobis (8-quinolyloxo) Vanadium(V)[VO2O2]+ [(n.BuNH2)2]- , by preparing the composites with different percentage (2,3,4,5,6) wt% of this ion-pair additive. The experi…
In the shipbuilding and bridge construction industries, shop primer paint is coated to the surface of steel plates in order to protect them from rusting during a long fabrication period. However, when arc welding is applied to the primer-coated plates, the arc heat make decompose and vaporize the coating. Then, the ge…
Advanced environmental barrier coatings (EBCs) with a periodic layered structure consisting of two kinds of oxide materials such as Y2Ti2O7 (YT) and Al2O3, which have a large difference in refractive index, can be expected to effectively reflect thermal energy, in addition to preventing oxidation of an underling SiC/S…
Planning of the modern manufacturing systems that would be suitable for the most demanding cutting processes requires analysis of all technical and technological process parameters by applying scientific methods, modeling and optimal conditions of machining process and systems defining. In order to secure the planned…
We are currently developing an external-heating-type superconducting magnesium diboride (MgB2)-level sensor for a large liquid hydrogen tank as one of the basic technologies for the marine transportation of liquid hydrogen. Optimization of the sensor performance and effect of sensor length on thermal response were pre…
A combination of physicochemical analysis methods is used to study the phase equilibria in the Cu-In-Pd system. An isothermal section at 800°C has been constructed. The copper solubility in the binary phases of the In-Pd system is determined.
Single-site Rh(CO)2, Rh(C2H4)2 and Rh(NO)2 complexes anchored on various dealuminated HY zeolites can be used as precursors for the selective surface mediated synthesis of well-defined site-isolated Rh(CO)(H)x complexes. DFT calculations and D2 isotope exchange experiments provide strong evidence for the formation of…
High surface texture of textile materials appears rougher and more porous than other printing substrates which can cause excessive ink penetration. Also, high temperature thermal loads affect the characteristics of printed ink and cause structural changes of the textile substrate material as well. The aim of this pape…
The aims of the present study were to detect the allelic and genotypic polymorphisms in a coding region of the ovine prion protein (PrP) gene and to test their association with productive performance of Barki lambs. Fifty four male lambs of Barki sheep were genotyped for the PrP gene using the polymerase chain reactio…
To investigate the processes of geometrically nonlinear deformation of plates and shells made of composite materials with differently shaped cutouts, conservative difference schemes are being developed within the framework of Timoshenko's model that allow one, on the basis of the variational- difference approach joint…
Within the scope of the presented work a hull girder ultimate strength analyses of the double hull oil tanker structures damaged by the collision or grounding is performed.An incremental-iterative progressive collapse analysis method prescribed by the forthcoming IACS Harmonized Common Structural Rules (H-CSR) is used…
This review summarizes and discusses electrophoretic methods for the fabrication deposited graphene and graphene-based structures. Graphenes are commonly dispersed in organic solvents or in water. Deposition procedures are performed mostly under constant voltage and deposition time seems to be an important parameter f…
Lead zirconate titanate (PZT) (P b Z r O 3 - P b T i O 3 ) were prepared by mixed oxide method at 1100 o C. Crystalline nature of the synthesized PZT has been confirmed by X-ray powder diffraction studies. The particle siz e and strain is calculated from X-ray peak broadening analysis b y using Williamson-Hall plot. T…
Asian Journal of Chemistry, a Multidisciplinary Chemistry Journal is an Peer Reviewed International Journal and publishes from India. The journal has been established since January 1989 on a firm foundation of International Quality Research. This Journal encompasses all branches of chemistry and its sub – disciplines…
The fluroquinolone family member ciprofloxacin is well known for its drug design and coordinating ability towards metal ions. The coordination chemistry of this drug with metal ions of biological and pharmaceutical importance is of considerable interest. Novel Ag (I) complex of Ciprofloxacin(CIP) was synthesized and c…
Controlling the behavior of adsorbed and immobilized proteins is essential for protein purification and a wide range of applications, including biosensors, biocatalysis and biomedical devices. In this study, monodisperse polymer particles were synthesized by soap free emulsion polymerization and the surface functional…
The austenite-to-martensite transformation at temperatures below room temperature was investigated in situ by magnetometry in Fe-N, Fe-Cr-C and Fe-Cr-Ni based alloys.After quenching to room temperature, samples were immersed in boiling nitrogen and martensite formation was followed during subsequent heating to room te…
The sprayed pyrolysis technique was carried out to prepare CuO thin films with different Mn-doping. Optical properties were calculated by recording the absorption spectra by UV-Visible spectrophotometer. The absorbance and absorption coefficient are increased with increasing Mn-doping in the CuO thin films. While the…
