In a focused ion beam (FIB) microscope, source particles interact with small volume of sample to generate secondary electrons that are detected, pixel by pixel, produce micrograph. Randomness the number incident causes excess variation in micrograph, beyond underlying particle-sample interaction. We recently demonstrated joint processing multiple time-resolved measurements from single can mitig...

The magnetite (Fe3O4) – agar nanocomposite was prepared by co-precipitation of Fe (III) and Fe (II) ions for the first time. The obtained samples were characterized by x-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. FT-IR results confirm the formation of Fe3O4 nanoparticles...

Membrane-binding of a human blood clotting protein, factor VIII (FVIII), was studied by cryoelectron microscopy. Well visible gap junctions between adjacent phosphatydyl serine containing phospholipid vesicles were observed upon FVIII association. Digital images acquired with a JEOL2010FEG transmission electron microscope equipped with a 4x4k CCD camera were analysed with the Digital Micrograph...

low temperature plasma technology is well established in surface modification of polymer materials on industrial scale. this method modifies surface properties of polymers without chemicals, manual work and reducing chemicals and energy consumption. in this study, low pressure plasma treatment was used to develop hydrophilic properties of polyethylene terephthalate (pet) fabrics. it was found t...

Cadmium Sulfide crystals were grown by direct vapor transport (DVT) from high-purity starting materials. The grown CdS crystals were orange in color, transparent, dendrite platelets shaped were observed. The structure of CdS crystals has been studied with the help of X-ray diffraction (XRD) and Transmission Electron Microscope (TEM). The crystals grown by DVT technique possess hexagonal structu...

A structure is proposed for the hexagonal form of MnAl(4), with a(H) = 28.4 A and c(H) = 12.43 A, on the basis of a high-resolution electron micrograph and comparison with crystals of known structures. The proposed structure involves seven 104-atom complexes of 20 Friauf polyhedra, sharing some atoms with one another. It is closely related to the 23.36-A cubic structure of MnAl(4) and to the 14...
