Zn1-2xCoxMnxO (x = 0.03 and 0.05) bulk samples were synthesised by a standard high temperature solid state reaction technique at 1,400 C. Characterization techniques X-ray diffraction, Vibrating Sample Magnetometry and Scanning Electron Microscopy with Energy Dispersive Analysis of X-rays were used to investigate effect of transition metal element Co and Mn incorporated in the system using high temperature technique. The magnetic, structural, electron density distribution and bonding properties have been investigated for the samples prepared in this work. X-ray diffraction analysis of the synthesized samples showed a single phase ZnO wurtzite structure for x = 0.03 and very slight segregation of a spinel phase for x = 0.05. Magnetization measurements indicate no evidence of ferromagnetism in co-doped (Co and Mn) ZnO. The structural and electron density analysis presented in this work is based on the actual concentrations of Co and Mn ions introduced in the matrix which nearly coincide with the nominal concentrations. © 2013 Springer Science+Business Media New York.

In this paper, an effect of clay on the strength characteristics of cement mortar have been investigated with chemically activated clay as a partial replacement of cement. The clay can be chemically activated with 0.25M NaOH solution and used in the proportions of 0%, 2.5%, 5%, 10%, 12.5%, 15%, 17.5% and 20% by weight of cement. The mechanical properties such as Compressive strength, Split tensile strength and Flexural Strength of the clay mortars were studied at the age of 28days. It was found that the strength of the cement mortar has been significantly increased by using chemically activated clay. The optimum clay replacement was found to be 2.5% in the presence of 0.25M NaOH solution. The XRF and FTIR test were done to the chemical composition and identification of minerals. The result of this investigation exhibits significant improvement in mechanical properties with evident from strength test. © 2015 CAFET-INNOVA Technical Society All rights reserved.

CdSxSe1-x films were deposited by the electron beam evaporation technique on glass substrates at different temperatures in the range 30-300 °C using the laboratory synthesized powders of different composition. The films exhibited hexagonal structure and the lattice parameters shifted from CdSe to CdS side as the composition changed from CdSe to CdS side. The bandgap of the films increased from 1.68 to 2.41 eV as the concentration of CdS increased. The root-mean-roughness (RMS) values are 3.4, 2.6, 1.2 and 0.6 nm as the composition of the films shifted towards CdS side. The conductivity varies from 30 ωcm-1 to 480 ωcm-1 as the 'x' value increases from 0 to 1. The films exhibited photosensitivity. The PL spectrum shifts towards lower energies with decreasing x, due to the decrease of the fundamental gap with Se composition. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Diluted magnetic semiconductor Ge1−xVx with three different dopant concentrations x = 0.03, 0.06 and 0.09 has been grown using melt growth technique. Scanning electron microscopy was used to analyze the surface morphological nature of the samples. Magnetic measurements taken using vibrating sample magnetometer reveal the diamagnetic nature for x = 0.03 and antiferromagnetic for x = 0.06 and 0.09. Powder X-ray diffraction data sets were collected for the samples and the structure was analysed using profile refinement technique and charge density was analysed using the versatile statistical tool maximum entropy method. Charge density analysis reveals that when x = 0.06 and 0.09 the system exhibits covalent bonding and picturises the signature of antiferromagnetism. The local structure was analyzed using pair distribution function technique. © 2015, Springer Science+Business Media New York.

Chemical structure of hydroxyapatite (HA) is very close to human bone which makes it compatible with the tissue of the human body. Its good biocompatibility makes it to be used extensively in many prosthetic applications, especially as a porous material for optimal bone in growth. Currently, this material is being deposited on bio-inert metallic implants and used as recovery parts in human body. In this present study a high-power plasma jet known as gas tunnel type plasma torch (GTTP), was used to produce HA and YSZ reinforced HA coatings on stainless steel substrate. In this study, microstructure, tribological properties and bioactivity of the GTTP sprayed HA and YSZ reinforced HA coatings was investigated. The XRD spectra of the as-sprayed coatings showed that the as-sprayed pure HA coating retained its crystalline HA phase similar to the initial feed stock HA powder, even though there existed a possibility for occurrence of decomposition during its in-flight in high temperature plasma zone. In the present case the decomposition processes of in-flight HA could be well controlled by means of selective operating parameters and unique nature of GTTP jet. The presence of un-melted particles and pores inside the coating microstructure play a vital role in the bonding strength of the coating. © (2013) Trans Tech Publications, Switzerland.

The inhibition efficiencies of Octyl alcohol (OCAL) and propargyl alcohol (PRAL) on the corrosion of mild steel in 15% commercial hydrochloric acid have been evaluated by mass loss method, electrochemical techniques and surface analysis techniques with 0-1% inhibitor concentration at 30 °C and 105 °C. Both OCAL and PRAL are excellent inhibitors for the above-mentioned system. OCAL gives 87% and 82% inhibition efficiencies at 30 °C and 105 °C, respectively, for 1% inhibitor concentration whereas PRAL gives 100% and 99% efficiencies at 30 °C and 105 °C, respectively, for 0.6% inhibitor concentration. Polarization studies confirm that OCAL and PRAL are mixed type inhibitors. OCAL and PRAL obey Temkin's adsorption isotherm at both the temperatures. UV-reflectance, FT-IR and SEM studies confirm that the surface of mild steel is not affected at the maximum concentration of OCAL and PRAL. © 2009 Elsevier B.V. All rights reserved.

In this study, Co-doped Zn1-x Co x O (x = 0.04, 0.06, 0.08, and 0.10, where x is the concentration of guest atom cobalt in the ZnO lattice) bulk samples were examined to determine the effect of doping on electronic, structural, magnetic, and optical properties. The samples were prepared using a standard high-temperature solid-state reaction technique. All samples were characterized by x-ray diffraction (XRD), magnetization measurements using vibrating-sample magnetometry (VSM), optical absorption spectroscopy, and scanning electron microscopy (SEM) with energy-dispersive x-ray spectroscopy (EDAX). The electron densities derived from the maximum-entropy method (MEM) show an improvement of electronic charge densities with Co impurity addition. The magnetic measurements at room temperature show variations in ferromagnetic behavior with respect to Co addition. The optical study shows a decrease in energy gap of ZnO with increasing cobalt content. © 2013 TMS.
