Some electrochemical properties of polycrystalline tin oxide in the form of thin films have been examined. For a variety of antimony‐doped specimens the carrier concentration has been determined from the space charge capacity and compared with donor concentrations. Disparities between the two values have been found, a…
Les propriétés magnétostatiques des manganites de terres rares, TMnO3, ont été étudiées entre 2 et 1 500 °K environ. Ces composés sont antiferromagnétiques ; les points de Néel sont à des températures inférieures à 100 °K. On discute cet antiferromagnétisme dans un modèle du champ moléculaire ; on détermine l'ordre de…
The equilibrium and dynamic aspects of the dielectric behaviour of polymer systems are considered in macroscopic terms and molecular terms. The role of dipole moment correlations is considered for a model polyether series. It is suggested that studies of certain copolymers reveal that the reorientation term 〈µk(0). µk…
CN has been trapped as a randomly oriented molecule in argon, krypton, and neon matrices at 4°K. The ESR spectra of 12C14N and 13C14N in their ground Σ+2 states have been determined and yield the following magnetic parameters in solid argon: g‖ = 2.0015(5), g⊥ = 2.0003(5), A‖(14N) = + 18.2(4) MHz, A⊥ (14N) = − 28.0(3)…

Les isothermes d’adsorption de krypton, xénon et méthane sur des surfaces homogènes de graphite exfolié, présentent un nombre de marches plus grand que sur les graphites habituels. On leur applique l’équation de CHAMPION et HALSEY et on vérifie que le potentiel d’adsorption décroît, d'une couche adsorbée à la suivante…
Refinement of crystal structures incorporating an extinction parameter in an approximation developed by Zachariasen has led to the experimental observation that some crystals show anisotropic extinction effects. A formalism is presented for refinement of anisotropic extinction coefficients for both extreme crystal typ…
Hydrogen is an environmentally friendly fuel that is promoted as one of the most promising alternative energies to replace fossil fuels. The production of hydrogen through the hydrolysis reaction of aluminum is a solution to overcome the problems in the current hydrogen production method. The production of hydrogen th…
Cerium doped barium titanate is prepared by conventional ceramic method. The dielectric studies of Ba1-x Cex TiO3 have been accomplished at room temperature over a frequency range 75 KHz to 30 MHz for x = 0.1 to 0.4 with pure BaTiO3. The measurements of the real and imaginary part of dielectric constants show strong f…
Significant increases in tensile strength and slight decreases in ductility occur when titanium and titanium-base alloys are irradiated at 17 K to 1 to 10×1017 fast neutrons per square centimeter. The magnitude of the irradiation effect appears to depend on total alloy content and, over the fluence range investigated,…
A total of 97 phytoplanktonic algal taxa belonging to 17 genera under two classes (Euglenophyceae and Bacillariophyceae) have been recorded from a pond receiving effluents from two textile industries at Demra, Dhaka district. Five diatom species, namely Navicula cryptocephala Kütz., N. decussis Oestrup, N. rhynchoceph…
Abstract Mössbauer spectra of Ga t Fe 3− t O 4 ( t = 0.44) were taken at temperatures from 88 to 740 °K. The A‐ and B‐site Zeeman patterns are resolved. The B‐site pattern displays a variation of hyperfine field arising from a distribution of the non‐magnetic gallium ions in the A‐site. The spectra were analyzed by a…
Occurrence of blue-green algae in plain land, pond side, hilly area and dry rice field soils of Chittagong University Campus and N2 fixation of some of them have been studied. Twenty four species under 20 genera were identified and their number varied from 0.11Ã104/g to 2.8Ã104/g soil. Anabaena oryzae, Calothrix sp.…
Soybean oil is one of the major vegetable oils containing more than 99% of triglycerides of saturated and unsaturated fatty acids and has become an interesting source to produce bioplastic. This study investigates the synthesis and characterization of bioplastic developed by the acrylate epoxidized soybean oil through…
Powder mixtures of zirconium diboride and molybdenum disiliside were hot-pressed at the temperatures ranging from 1500° to 2200°C in graphite dies under the pressure of 200kg/cm2 in order to improve densifying and oxidation resistance properties. Pressure was applied through out the experiment and shrinkage of the com…
The equilibrium distribution coefficient of boron in germanium was found to be 12.2. The variation with growth rate was interpreted in terms of a theory by Burton, Prim, and Slichter. As the growth rate was increased the width of the diffusion dominated layer initially increased followed by a later decrease. This was…
Abstract The results of high strain‐rate tensile straining of a variety of elastomers at a number of temperatures are reported. Temperature increases, Δ T , occurring within the sample were measured during the deformation; i.e., the technique of adiabatic stretching was applied. The use of well characterized rubbers o…
The compound CsCrCl3 is antiferromagnetic, whereas the compounds M2CrCl4(M = NH4,K,Rb,Cs) are ferromagnetic and their dihydrates are normally paramagnetic.
