Refractory high entropy alloys are an interesting material class because of their high thermal stability, decent electrical conductivity, and promising mechanical properties at elevated temperature. In the present work, we report on the thermal stability of body-centered cubic MoNbTaVW solid solution thin films that were synthesized by cathodic arc deposition. After vacuum annealing up to 1600 °C, the morphology, chemical composition, crystal structure, and electrical conductivity, as well as the mechanical properties, were analyzed. The observed body-centered cubic MoNbTaVW solid solution phase is stable up to 1500 °C. The evolution of electrical and mechanical properties due to the annealing treatment is discussed based on the observed structural changes of the synthesized thin films.

This study aims to investigate the effect of SWCNT nanofiller on mechanical properties and electrical conductivity of PVA/CS/GA nanocomposite film. Polyvinyl alcohol (PVA) and chitosan (CS) are used as polymer matrix that crosslinked by glutaraldehyde (GA). Nanofiller SWCNT was inserted in a polymer composite matrix at different composition. The thin films were characterized using FTIR (Fourier Transform Infrared Spectroscopy), XRD (X-ray diffraction), SEM (Scanning Electron Microscopy), TG/DTA (Thermal Gravimetric/Differential Thermal Analysis), sheet resistance, and tensile strength measurements. The results revealed that the addition of SWCNT notably increased the electrical conductivity of composite film from 1.2 x 10‒4 S.cm‒1 to 9 x10‒3 S cm‒1 as well as tensile strength and elongation 43 MPa to 62 MPa, 68% to 84%, respectively. The cross-sectional SEM images indicated that the conductive thin films have a layered structure where the insertion of SWCNT did not change their morphological structure significantly. Additionally, SWCNT improved the thermal stability of PVA/CS/GA nanocomposites thin film. These finding can be promising for the development of optoelectronic devices i.e. photovoltaic, emitting diodes, etc.

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.

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
