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…
Nano ferrites with general chemical formula CuxCo1-xFe2O4 (x<1) were synthesized by sucrose method and characterized by X-ray diffraction and IR studies. DC resistivity shows break near Curie temperature indicating the change in conduction mechanism. AC resistivity exhibits large dispersion at low frequency which is i…
MAX phase materials are layered ternary carbide or/and nitride compounds with general formula MN+1AXN where M is an early transition metal, A is a Group IIA or IIIA element and X is C or N. These materials combine certain properties of metals, such as good electrical and thermal conductivity, low hardness, machinabili…
Zinc salts of L-proline, D-proline were used in homopolymerization of L, L-lactide and D, L-lactide. Linear PLA oligomer with Mn 2900-3400 Da, can be prepared with zinc (L-prolinate)2 catalyst. Less racemization were occurred in presence of Zn (L-prolinate)2 than Zn (D-prolinate)2. The catalyst structure of Zn (L-prol…
