Block Polymers and Related Heterophase Elastomers
Recently, there has been considerable interest in heterophase polymer systems which possess enhanced physical properties in the elastomeric state. These systems, with their improved properties, greatly expand the list of available engineering materials and the possibility of designing a material to perform in a given…
Band Structure of Transition Metals Studied by ESCA
The position and shape of the energy bands of the following transition metals have been studied by ESCA: Fe, Co, Ni, Cu, Ru, Rh, Pd, Ag, Os, Ir, Pt, Au. The Fermi levels of the metals with unfilled d -bands are found in the high-energy flanks of the valence band spectra. For the noble metals the Fermi level is shifted…

Effect of weft parameters on weaving performance and fabric properties
Threads per inch and yarn count are some of the most important parameters that affect both weaving performance and fabric property. Experimental studies were conducted by weaving fabrics with three different picks per inch (PPI) and weft counts. The study shows that weaving performance is affected by the too high cove…
Grafting of n-butyl acrylate with natural rubber latex film by gamma radiation: a reaction mechanism
Natural rubber latex (NRL) and n-butyl acrylate (n-BA) were blended and irradiated at various absorbed doses by gamma rays from Co-60 source at room temperature. The stabilizing effect was determined by measuring the pH and viscosity of NRL with n-BA with the storage time of five weeks. The cross-link density, swellin…
Modern tungsten-halogen-lamp technology
Since the innovation of the practical tungsten-halogen lamp employing iodine as the regenerating agent, there has been continuous research and development in this field of lamp technology. Although there are still gaps in our knowledge, particularly regarding the kinetics of certain reactions, there is now a far bette…
A thermogravimetric method for the analysis of mixtures of brushite and monetite
A thermogravimetric method is described for the quantitative analysis of mixtures of calcium hydrogen orthophosphate dihydrate (brushite) and anhydrous calcium hydrogen orthophosphate (monetite) based on their loss of water on heating. An extension to the method when the above system contains a third component of know…

Etch Pits and Crystal Structure of Tellurium
Abstract E. Takimoto The shapes of the asymmetric etch pits produced by slow action of hot sulfuric acid on the cleavage planes of tellurium crystals have been investigated, and a microscopic model is proposed for the formation of the etch pits. The handedness of the spiral chains and the positive direction of the x ‐…
Green synthesis of silver nanoparticles from seed extract of Brassica nigra and its antibacterial activity
Abstract. Pandit R. 2015. Green synthesis of silver nanoparticles from seed extract of Brassica nigra and its antibacterial activity. Nusantara Bioscience 7: 15-19. We report the green synthesis of silver nanoparticles using seed extract of Brassica nigra. UV-visible spectroscopic analysis showed the absorbance peak a…
Reactions of polyolefins with strong lewis acids
Abstract Treatment of a cyclohexane solution of low density polyethylene and polystyrene with anhydrous aluminum chloride causes chemical reaction between the two polymers which results in the formation of a graft copolymer. The initial copolymer‐forming reaction is very rapid, and prolonged contact of the polymers wi…
Intrinsic Optical Properties of CrCl3
Abstract The intrinsic optical absorption spectrum of CrCl 3 has been investigated in the 0.6 to 6 eV region at temperatures from 80 to 300 °K. A careful analysis of the crystal field bands in the 0.6 to 3 eV region has revealed some structures and details, such as an Urbach's rule edge, not previously reported. The o…
The Defect Structure of Non‐Stoichiometric Germanium Telluride from Magnetic Susceptibility Measurements
Abstract The room temperature magnetic susceptibility of non‐stoichiometric GeTe has been measured; by calculating the contributions of the free carriers and the ionic lattice using the appropriate formulae and the known parameters of the system, the contribution to the susceptibility of the lattice defects has been o…
Radiation-Hardening and Recovery in Mild Steels and the Effects of Interstitial Nitrogen
The effects of interstitial nitrogen on the hardening produced in mild steels by irradiation at 50° C (323 K) to doses up to 2·6 × 1018 n/cm2 (fission) have been investigated. These studies were performed using annealed silicon-killed steel with a finite concentration of nitrogen in solution, annealed silicon-killed s…
Investigation of mechanical properties of luffa cylindrica fibre reinforced epoxy hybrid composite
In this present work, the effect of stacking sequence on mechanical properties of untreated luffa cylindrica and glass fibre reinforced epoxy hybrid composites has been investigated experimentally. Composite laminates were fabricated by hand lay-up technique. All the composites were made with a total of 4 plies, by va…
The Corrosion of Titanium Carbide
In , the anodic dissolution of titanium carbide begins at about 0.8V ( SHE ). Trivalent titanium ions could not be detected in the nitrogen‐ saturated solution, although this does not rule out the possibility that Ti(III) is formed in the dissolution reaction. However, at 0.8V oxidation to Ti(IV) would readily occur.…
Sensitivity of Fish Pathogenic Bacteria to Various Medicinal Herbs
The sensitivity of certain local medicinal herbs was evaluated against pathogenic Aeromonas hydrophila, Pseudomonas fluorescens and Edwardsiella tarda bacteria of fish during the period from April 2001 to March 2002. A suspension of freshly cultured experimental bacteria (2 x 107 CFU / ml) was prepared and 0.1 ml of t…
