Background: Composite materials reinforced by glass fibers are widely used in various applications ranging from aerospace to sporting goods due to their remarkable properties including high strength to weight ratio and high modulus to weight ratio. However, the addition of nanoparticles as reinforcement shows promisin…
The new company, called The Advanced Composites Group, will develop solutions and services to improve and enhance the performance of composite materials and structures by joining the efforts of Niles International’s NExT Aerospace division and Boyce Components’ expertise in composite heating systems. Immediate plans c…
This study focuses on the comparison of the mechanical properties of charcoal unsaturated polyester matrix composite and snail shell unsaturated polyester matrix composite. The ground charcoal powder and snail shell powder were of the same particle size of 625microns. The ground charcoal was introduced into the unsatu…
An attempt was made in the present work to develop a new plasticized proton conducting polymer electrolytes comprising of Poly (vinyl alcohol) (PVA) - Sulfamic Acid (SA) - Poly ethylene glycol (PEG400). The role of the plasticizer was studied in terms of dc conductivity (σdc), activation energy (Ea) and mobility of th…
This paper presented anodic oxidation characteristics of the thin film aluminum on metal substrate. Generally, the anodic oxidation process is performed using the high purity aluminum sheet or deposited aluminum on brittle ceramic substrates such as silicon, glass and sapphire. In order to obtain mechanical stability…
A feeding study is performed to investigate effect of nano-ceria on activity and gene expression of pancreatic amylase of hens, and the mechanism of its influence on digestive enzyme is discussed. Three hundred eighty four 26-week-old healthy commercial hens were selected and allotted randomly to four treatments, each…
Aspergillus foetidus have been used to synthesize biological silver nanoparticles and extracellular proteins were also isolated from the same strain. The interaction between fungal isolated protein and silver nanoparticles was investigated by UV- Vis spectroscopy, fluorescence spectroscopy and circular dichroism techn…
Electrical currents in resistive materials must be driven by an internal electric field E = J/ς, where J is the current density and ς is the electrical conductivity. The internal electric field must be shaped by an appropriate density σ of surface electrical charge. In practice, the surface charge density is quite sma…
Laminated composites ,which are manufactured with Aluminum(Al) and Polyethylene terephthalate (PET), are widely used in electrical cables sector in recent times. Aluminum which is commonly used with copper for the aim of preventing magnetic effects, here is used with PET while PET covering it. In this work composite m…
Wear is defined as removal of material from solid surfaces as a result of mechanical action. It is a characteristic feature of the wear process that the amount of material removed is quite small. However wear in sliding systems is usually a very slow process that is very steady and continuous.Slurry abrasion is define…
In this work, n-CdS/p-InSe heterojunction structures were fabricated by successive thermal evaporation of CdS and InSe powders. The photovoltaic properties of SnO2/nCdS/p-InSe/Metal sandwich structures were investigated through I-V, C-V and spectral response measurements. Various metal point contacts such as Ag, Au, I…

In mulberry silk, apart from the quality of raw materials i.e., silkworm cocoon, the production of raw silk quality yarn is greatly influenced by the reeling process that includes type of contrivance along with several other factors. An attempt has been made in this study to get an idea on the combining effect of mach…
impediment to graphene research is the need to manually characterize the thickness of high-quality graphene produced via mechanical exfoliation. Traditional methods of characterizing the layer thickness of graphene, including Raman spectroscopy and atomic force microscopy, require expensive equipment and can be damagi…
Recent calculations concerning the shape of the quadrupole used as a focusing lens revealed a potential progress margin especially for short devices*. The main issues of the paper are related with the improvement of the performances of some standard quadrupolar focusing equipments considered here with an electrostatic…
A Cu(II) complex of a ligand [L] derived from salicyloyl hydrazide and furfuraldehyde has been prepared. The ligand and metal complex were characterised by elemental analysis, magnetic measurement, molar conductance, FTIR, UV-Vis spectra, ESR and mass spectral studies. Analytical data suggests the molecular formula of…
Wear is the predominant factor that controls the life of any component. Metal parts often fail their intended use not because they fracture, but because they wear, which causes them to lose dimension and functionality. Different types of wears exists , but the most typical modes are abrasion, impact, metallic (metal t…
Nanoparticles of [Pb0.7 La0.2] TiO3 ceramics were prepared by conventional combustion technique from the oxides of PbO, La2O3 and TiO2 with different sintering time (ts) (2, 6, 10, 12, 16 and 20h) while keeping the calcination temperature at 1200 o C. Particle size of the samples was estimated between 25 to 65 nm thro…
Impact testing methodology is findings the applications for determining the impact strength of the different materials. Oneof the most important characteristics of structural steels, toughness is assessed by the Charpy V-notch impact test. The objective of the research was to maximize the impact toughness by selecting…
We report the synthesis of organic nanofibers with embedded palladium nanoparticle (PdNP) by the self-assembly of Pd2+-coordinated lithocholic acid (LCA) in the presence of sodium borohydride(NaBH4) or ascorbic acid (AA) reducing agents. The in-situ reduction of Pd2+ ions by NaBH4 or AA leads to the formation of PdNPs…
