CdHgTe thin films were grown onto glass substrate via the Chemical bath deposition technique. XRD results indicate that a CdHgTe formed with a cubic polycrystalline structure. The crystallinity of CdHgTe thin films is gradually deteriorate with increasing the gamma irradiation. EDS spectrums confirms the presence of Cd, Hg and Te elements. DC electrical conductivity results depicted the conductivity of CdHgTe increase with increasing a gamma ray dosage

Abstract In this study, chalcogenide material Ge 10 Se 70 Bi 20 thin films have been fabricated utilizing the thermal evaporation technique of bulk samples on glass substrates. After that, the original Ge 10 Se 70 Bi 20 thin films irradiated by different types of an ion beam. The compositions of the original film was determined by the Energy Dispersive X-Ray (EDX). X-ray diffraction (XRD) measurements were performed to characterize and examine the induced variations in the structure of Ge 10 Se 70 Bi 20 films after irradiation. From the optical measurements, the absorption edge, bandgap, Urbach energy, Tauc parameter, and extinction coefficient of the unirradiated and irradiated films were determined. In particular, the DC electrical conductivity increased by two orders after the pure film was exposed to an oxygen ion beam. Besides, the activation energy and Mott’s parameters for the original and irradiated Ge 10 Se 70 Bi 20 films were deduced. The reported variations in absorption coefficient, optical bandgap, dc electrical conductivity, and Mott’s parameters propose that the irradiated Ge 10 Se 70 B 20 thin films can be used in important applications, e.g., optical data storage and optoelectronic devices.

TiO2 has been synthesized using Titanium isopropoxide as precursor solution. Different amount of Titanium isopropoxide of 0.2, 0.4, 0.6, 0.8 and 1 mol concentration used to synthesis TiO2 . Different mol concentration solution has been blend with Camphor sulfonic acid protonated Poly (2, 5-dimethoxyaniline) and cast as thin film by dip coating. The optical and XRD analyses were carried out for the dip coated TiO2 thin films. The DC electrical conductivity was measured for the dip coated Camphor sulfonic acid protonated Poly (2, 5-dimethoxyaniline) /TiO2 blend thin films. The Titanium isopropoxide of 0.6 mol concentration shows better UV-Vis absorption and crystalline nature. Camphor sulfonic acid protonated Poly (2, 5-dimethoxyaniline) /TiO2 blend thin film of 0.6 mol concentration shows higher DC electrical conductivity when compared to other mol concentration.

High magnification imaging of macromolecules on metal coated biological specimens is limited only by wet preparation procedures since recently obtained instrumental resolution allows visualization of topographic structures as smal l as 1-2 nm. Details of such dimensions may be visualized if continuous metal films with a thickness of 2 nm or less are applied. Such thin films give sufficient contrast in TEM as well as in SEM (SE-I image mode). The requisite increase in electrical conductivity for SEM of biological specimens is achieved through the use of ligand mediated wet osmiuum impregnation of the specimen before critical point (CP) drying. A commonly used ligand is thiocarbohvdrazide (TCH), first introduced to TEM for en block staining of lipids and glvcomacromolecules with osmium black. Now TCH is also used for SEM. However, after ligand mediated osinification nonspecific osmium black precipitates were often found obscuring surface details with large diffuse aggregates or with dense particular deposits, 2-20 nm in size. Thus, only low magnification work was considered possible after TCH appl ication.

Cellulose Acetate Membranes

Ultrafiltration cellulose acetate membrane can be transformed by annealing into reverse osmosis membranes (RO type). Annealing brings about changes in structural properties of the membranes, accompanied by changes in their permeability behaviour and electrical properties. Correlations between structure parameters and electrochemical properties are shown for the temperature range 20-90 °C. Relations have been derived which explain the role played by the dc electrical conductivity in the characterization of rejection ability of the membranes in the reverse osmosis, i.e. rRO = (1 + exp (A-B))-1, where exp A and exp B are statistically significant correlation functions of electrical conductivity and salt permeation, or of electrical conductivity and water flux through the membrane, respectively.
