Afterwards, vials were sealed with aluminum caps and incubated at 37 oC for 7 days. In this section, mediator was added in the modified medium, which carbon sources were completely reduced. The purpose of doing this is to investigate that if the electron promoters will

carbide tipped mill tool and four fluted solid carbide mill tool. In this regard the experimentations were conducted with varied milling process parameters and the results were thoroughly evaluated and analyzed with origin interface graphs and scanning electron micro (SEM) graphs to understand post machined surface textures.

nanostructured metal oxide film serving as a photoanode, a Pt-coated counter electrode and liquid electrolyte injected between them [3]. Light irradiate on the nanostructured metal oxide film causes photo-excitation of the dye molecules by exciting electrons which are then injected into the conduction band of the semiconductor and fast transferred to the external circuit
xxxxxxxxx Abstract In this paper, PVA-AgNO3 films were prepared by casting method. Then irradiated with different gamma doses (25, 50, 75, 100, 125 KGy). UV–visible spectroscopy, scanning electron microscope, EDX and photoluminescence spectroscope were used to characterize the prepared films. UV–visible absorption spectra showed a peak at 200 nm for PVA. And a peak at 427 nm for the surface plasmon resonance of silver nanoparticles. This peak
Introduction Usage of natural antioxidants from plants and the other natural sources has been among the most important ingredients in food and pharmaceutical industries. Having the ability to defend against the reactive oxygen stress (ROS),Natural antioxidants can protect the human heath from a lot of diseaseses, they are Generally Recognized As Safe (GRAS) and the have less toxicity in industrial products compared to the artificial synthetic ones. Zingiberaceae is a family in the plant kingdom
The doping of semiconductor by rare earth metal nanoparticle is an effective way for increasing photocatalytic activity. Zinc oxide and Lanthanum doped Zinc oxide nanoparticles were synthesized by modifying the gel-combustion method. It was found that La can greatly enhance the cytotoxicity and photocatalytic activity of ZnO nanoparticles towards various cell lines and paracetamol drug. These nanoparticles were characterized by various spectroscopic and other techniques which clearly revealed the
About 70% of the new chemcial ntities are recognized as poorly water-soluble about 40% of commercially available immediate-release oral formulations are recognized as practically insoluble in water (Kawabata et al., 2001). Therefore, several potentially promising drug candidtates were rejected as pharmaceutical products due to ther poor solubilitty in GI fluid, poor dissolution in GI tract, low systemic absorption and thus poor oral bioavailability (therapeutically ineffective) (Hörter and Dressman
