Antibacterial and antifungal activity of various extracts of Bacopa monnieri [PDF]

open access: yesarXiv, 2019
Bacopa monnieri was also known as Brahmi. Theses plant has been considered as medicinal plants in Ayurvedic systems for centuries. This present study was carried out to evaluate the antibacterial and antifungal properties of ethanolic, diethyl ether, ethyl acetate, and aqueous extracts of B. monnieri.

Lightlike Hypersurfaces of Metallic Semi-Riemannian Manifolds [PDF]

open access: yesarXiv, 2018
In our article, we introduce and study lightlike hypersurfaces of a metallic semi-Riemannian manifold. We examine some geometric properties of invariant lightlike hypersurfaces. We show that the induced structure on an invariant lightlike hypersurface is also metallic.

Semiconductive and Photoconductive Properties of the Single Molecule Magnets Mn12-Acetate and Fe8Br8 [PDF]

open access: yesarXiv, 2003
Resistivity measurements are reported for single crystals of Mn12-Acetate and Fe8Br8. Both materials exhibit a semiconductor-like, thermally activated behavior over the 200-300 K range. The activation energy, Ea, obtained for Mn12-Acetate was 0.37 +/- 0.05 eV, which is to be contrasted with the value of 0.55 eV deduced from the earlier reported ...

One step growth of PVP spheres embedded with nearly monodispersive CdS nanocrystals using chemical bath deposition [PDF]

open access: yesarXiv, 2014
We have used simple chemical bath deposition technique to grow nearly monodispersive CdS nanocrystals in PVP matrix. Systematic study of variation of growth parameters has revealed that optimized growth of CdS nanocrystals in PVP matrix depends on relative concentration of Cd acetate/Thiourea to polyvinyl pyrrolidone in the bath.

Alternating Current Electrothermal Flow for Energy Efficient Thermal Management of Microprocessor Hot Spots [PDF]

open access: yesarXiv, 2018
The paper presents numerical results on an innovative concept of an efficient, site-specific cooling technology for microprocessor hot spots using Alternating Current Electrothermal Flow (ACET). ACET deploys an electrokinetic transport mechanism without requiring any external prime mover and can be shown to be highly effective in reducing hot spot ...
