To evaluate the anti–inflammatory property of leaf exacts Gendarussa vulgaris (G. vulgaris) Nees. G. Nees family Apocynaceae is a medium sized tree grown in semishade or no shade and common Ernad Nilambur taluks Kerala. Various parts this plant have been used treatment ulcers, sores, inflammation, dyspepsia, healing wounds, etc. The present study aimed at evaluation aqueous alcoholic extracts leaves by both vitro vivo methods. In method was estimated human red blood cell membrane...
DC and AC magnetic measurements indicate the presence of multiple transitions arising from competing interaction between Cr Mn in perovskite La2CrMnO6. Ferromagnetic spin glass are observed The material also has a Griffith-like phase with occurrence ferromagnetic short range correlations above TC. system ultimately turns into paramagnetic at Griffiths temperature 180 K. A combination variable hopping, nearest neighbor small polaron hopping governs conduction mechanism material. negative...
An easy and convenient method for the synthesis of cobalt magnesium ferrite nanoparticles is demonstrated using liquid foams as templates. The foam formed from an aqueous mixture anionic surfactant desired metal ions, where ions are electrostatically entrapped by at thin borders between bubbles their junctions. hydrolysis carried out alkali resulting in formation nanoparticles, with playing role a template. However, ferrites formula MFe2O4, ion iron possess oxidation states +2 +3,...
The magnetic properties of different compositions in the self-doped lanthanum manganites, ${\mathrm{La}}_{1\ensuremath{-}x}\mathrm{Mn}{\mathrm{O}}_{3}$, have been studied by ac susceptibility and dc magnetization measurements temperature range $10--300\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. All with $x<0.125$ show an anomalous decrease zero field cooled (ZFC) at low temperatures, below ferromagnetic ordering temperature. which this behavior is observed, ${T}_{a}$, varies degree La vacancy...
Studies on a large number of compositions among the ferromagnetic self-doped manganites, La1−xMnO3, show that Curie temperature increases with x and reaches maximum value for = 1/7. Tc remains independent ≥ 1/7 magnetization is obtained 1/8. The presence second phase, due to Mn3O4, whose contribution x, observed in powder x-ray diffraction patterns > 1/8 lattice parameters remain results indicate limiting or extent self-doping possible La1−xMnO3
Uniform and well-dispersed IDC (indium doped cerium oxide) films are successfully deposited by Nebulizer Spray Pyrolysis (NSP) technique.
Three new isostructural tellurides Tl4MTe4 with M = Zr and Hf were prepared from the constituent elements. Single crystal X-ray diffraction data analyses showed that these compounds belong to a structure type, adopting space group R unit cell dimensions of 14.6000(5) Å c 14.189(1) when Zr, 14.594(1) 14.142(3) (Z 9). The consists atoms in distorted octahedra formed by Te atoms, which are face-condensed oligomeric M3Te12 units. refinement compound revealed an additional site, occupied 10%...
The thermoelectric properties of n-type InxPb1−xTe1−yIy (with x = 0.005, 0.01, 0.015; y 0.001, 0.002, 0.004, 0.006) were investigated at elevated temperatures up to 655 K. This co-doping significantly affected the Seebeck coefficient and electrical conductivity all samples within measured temperature regime except for sample with largest concentration In, wherein effects I-doping are comparatively minor. For a given amount iodine possesses highest conductivity, which is consistent three sets...
The tellurides Tl(10-x)La(x)Te(6) were synthesized from the elements in stoichiometric ratios at 873 K, followed by slow cooling. These materials are substitution variants of Tl(5)Te(3), crystallizing space group I4/mcm, with lattice dimensions a = 8.9220(4) Å, c 13.156(1) V 1047.2(1) Å(3), for x 1 (Z 2). Increasing La content occurs an increase unit cell volume and axis, but decrease axis. Tl(5)Te(3) is metallic compound, while Tl(9)LaTe(6) was calculated to be semiconducting....
