Previous studies of the effects of the interaction of electron beams with bilayers of amorphous chalcogenides and metals such as silver and copper have shown that the type of pattern formed by electron beams scanned across these bilayers is dependent

Nanoparticles of the spinel ferrite Mn0·7Zn0·3Fe2O4, with potential for use as contrast agents for magnetic resonance imaging applications, have been prepared by a sol–gel method followed by a two stage annealing process. The second stage of the

Metal migration and surface modification have been observed in metal-doped amorphous arsenic and antimony-based chalcogenide systems such as As2Se3 and Sb2S3 under the irradiation of an electron beam. Surface expansion of the order of 5–35% of the

Thin bilayer films of Cu/a-GeSe 2 and Ag/a-GeSe have been studied in the transmission electron microscope (TEM) for different metal concentrations. It has been observed that samples of Cu/a-GeSe 2 crystallise locally when the electron beam is fully f

The capsid protein (CP) of Cucumber mosaic virus (CMV) is required for cell-to-cell movement, mediated by the 3a movement protein (MP). Deletion of the C-terminal 33 amino acids of the CMV 3a MP (in the mutant designated 3aDeltaC33 MP) resulted in CP

Mechanical stress in the GexSb40−xS60 film/Si substrate system has been examined before and after film treatment (illumination and/or annealing). The intrinsic stress in the film was tensile. Stress dependence on the atomic percentage Ge content x

X-ray photoelectron spectroscopy has been used to determine the binding energies of the core electrons in Ag-doped amorphous thin GexSb40−xS60 films (x=15, 20, 25 and 27). Chemical shifts of the constituent elements have revealed that electrons are

The effects of post-treated oxygen plasma etching procedures have been investigated for amorphous carbon nitride (a-C:N) films deposited by dc magnetron sputtering. X-ray photoelectron spectroscopy (XPS) has been used to study the microstructure of t

This study examines the thermal decomposition of 1,5-cyclooctadiene platinum (II) chloride organometallic films, deposited by thermal evaporation. The thin film samples were annealed both in air and hydrogen with well-controlled temperature regimes.
