Structural and optical properties of Cr doped ZnO nanoparticles prepared by the thermal decomposition method are presented. X-ray diffraction studies confirmed the substitution of Cr on Zn sites without changing the wurtzite structure of ZnO. Modified form of W-H equations was used to calculate various physical parame…
Microbial induced corrosion (MIC) of reinforced concrete sewer piping and manholes is a significant issue in Australia and overseas costing water authorities hundreds of millions of dollars annually. It is anticipated that as the country's sewer infrastructure ages the problem will become more severe. Over the last 4…
TiO2 nanoparticles were pretreated with ethelendiamine (EDA) to synthesize aminefunctionalized TiO2. The mixed matrix membranes (MMM) comprised of aminfunctionalized TiO2 inside polysulfone (PSf) matrix were fabricated and characterized for gas separation. The effects of the amin-functionalized TiO2 loading on the gas…

The application of protective coatings on metal materials is the effective way to improve their durability. Chromium nitride coatings are applied mainly on tools due to good resistivity to oxidation compared to other metal nitride coatings and good wear resistance. Some characteristics of the coatings deposited in fix…
The dielectric properties of electrochemically grown zirconium oxide films by anodisation of zirconium in 1.0 mol dm-3 phosphoric acid solution were investigated in a 3 to 30 V potential range with a view to inducing surface modifications for eventual use in biomedical and electronic applications. The oxide films grow…
This review deals with the basis and novel trends in electrochromism, describing the basic aspects and methodologies employed for the construction and analyses of different modified electrodes. The work presents the classic materials used for the construction of electrochromic electrodes, such as WO3 and a view on the…
The research activity was focused on the optimization of heat treatment parameters for C355 (Al-Si-Cu-Mg) \ncast aluminum alloy and on its microstructural and mechanical characterization in T6 condition, also evaluating \nthe effect of subsequent high temperature exposure. Differential thermal analyses were carried ou…
In this research, carbon nanotubes were grown through thermal chemical vapor deposition. Argon, ethanol vapors, and nickel deposited on silicon substrate were used as a carrier gas, carbon source, and catalyst, respectively. The experiment was performed in atmospheric pressure at 650, 750, and 850 C for 15 minutes an…
Erbium zinc borotellurite, {[(TeO2)0.70(B2O3)0.30]0.7 (ZnO)0.3}1-y (Er3O2)y glasses were prepared by rapid melt-quenching method. The structural properties of the glass samples were determined by using x-ray diffraction (XRD) method and was confirmed its amorphous nature. The FTIR analysis shows that the Erbium Oxide…
2 Abstract: Primula is a medicinal plant bearing flowers which belongs to family Primulaceae. These are low growing herbs. Methanol and cold water extraction methods were used for leaves and roots extractions of Primulavulgaris. Antimicrobial activity ofleaves and roots extracts was evaluated by well diffusion method.…
Conventional liposomes are artificially prepared vesicles made of a lipid bilayer that can encapsu- late drugs and used as a drug carrier system for the treatment of cancer and other diseases. Encapsulation of a drug in liposomes prevents its early degradation and alters the biodistribution profile in the body. This e…
Progressive collapse in a structure occurs when major structural load carrying members are removed suddenly, and the remaining structural elements cannot support the weight of the building. This failure usually occurs in a domino effect and leads to a progressive collapse of the structure. The basic characteristic of…
Individual characteristics such as intelligence, cognitive styles, and personality play an important role in learning and instruction as does the context of learning. In the effort to improve students cognition and affective outcomes in mathematics and/or school learning, educational psychologists and mathematics educ…
With an increased use of nonlinear loads, sensitive electronic equipments and variable frequency drives power quality has become a prominent issue these days. The development of new methods for detection classification and analysis of power quality is a major concern now a day. This paper presents a literature review…
Lignocellulose is the chief component of the overall ecological biomass it is composed of major biological macropolymers such as cellulose, hemicelluloses and lignin. Hemicelluloses are complex mixtures of different polymers such as xylan, mannan, galactan, arabinan or other heteropolymers (Verma and Satyanarayana, 20…
Enlargement of biologically stimulated investigational processes for the synthesis of nanoparticles is budding into an important branch of nanotechnology. Eco responsive methods of green mediated synthesis of nanoparticles are the present research in the extremity of nanotechnology. The bioreduction behavior of leaf e…
Nanotechnology collectively describes technology and science involving nano scale particles (nanoparticles) that increases the scope of investigating and regulating the interplay at cell level between synthetic materials and biological systems. The experiment to evaluate the effect of different concentrations of nano-…
The present study deals with the design of composite rocket motor casing and compare results with metallic casing to quantify the improvement of performance factor. A systematic approach is adopted for modelling of various components (composite casing shell, igniter end, nozzle end, igniter skirt end and nozzle skirt…
MgxZn1-xFe2O4 (x = 0.65, 0.85) ferrite nanoparticles were prepared by a modified sol-gel method using high purity metal nitrates and aloevera plant extracted solution. Using of aloevera extract simplifies the process; provide an alternative process for a simple and economical synthesis of nanocrystalline ferrite. The…
