Glass Structure . Electrical Conductivity . Nano-compositesGold doped ruby glasses are classical examples of metal-glass nanocomposites that have been investigated for their striking optical properties. For their multifunctional applications, we have explored the nature of the electrical response of two oxide glasses containing a small amount (<0.1mol%) of gold. Gold-doped lithium borate (LBO) and lanthanum borogermanate (LBGO) glasses are studied using ac conductivity as a function of frequency and temperature in relation to their structure as determined by electron microscopy. For ionically conducting LBO, Au doping produces a noticeable increase of the electrical conductivity. For poorly conducting LBGO, gold doping introduces a dielectric loss peak indicative of dipolar relaxation. The heat treatment of both glasses introduces a new mechanism of dc conduction or dipolar loss, which has about one third the activation energy of the untreated samples. This unexpected behavior is attributed to an ionic-to-electronic conductivity transition in gold doped glasses.
Sulphamethaxazole is antibiotic used to treat several types of bacterial infections and gives double effect when used with trimethoprim by 1 to 5 of sulphamethaxazole. It has a broad spectrum effect on the positive and negative bacteria of Gram and fungi. The objective of this research is to convert sulfamethasazole to nano sulfamethasazole by Sol-gel method by using additive material like acetic acid, distilled water and ethanol with temperature 80°C and probe sonicator machine as catalyst and hydrolysis factor. Nano sulphamethoxazole solution analyzed by atomic force microscope (AFM) was show average of nano particles at size (50±10) nm. Scanned by TEM and SEM shows nano particles as a band of hollow tubes with a diameter less than 100 nm., beside the EDS pattern show high peaks of sodium, carbon and oxygen along with some other constituents. The antibacterial activity of nano solution shows respectable inhibition activity compared to slandered solution.
Nano peel solution was prepared using Sol-gel technology at a temperature of (80) Celsius. A number of tests were performed to describe the properties and structure of Nano material, including scanning probe microscopy (SPM), which showed the symmetric cumulative distribution of the solution Nanoparticles and the average grain size equal to 64.5 nm and the identical distribution of the Nanoparticles with a diameter of 37.75 nanometers, with a measurement area ranging between (1531.23-1558.19) nanometers. Nano-solution analyzed with a scanning electron microscope (SEM), Inspect type (S50), with a magnification power up to X2000, where dense flakes of Nano particles with a diameter of (50 ± 10) nanometers were observed. The antibacterial activity of Nano-solution by using gram- positive bacteria St. aurous and gram-negative E. coli show the inhibition diameter of (St. aurous) was 27 mm and 25 mm in (E. coli).
