Early effects of gamma rays and protons on human melanoma cell viability and morphology
(Journal of Microscopy, Oxford, 2008)
The effects of irradiation with gamma rays and protons on HTB140 human melanoma cell morphology and viability were analyzed. Exponentially growing cells were irradiated close to the Bragg peak maximum of the 62-MeV proton ...
Nanoparticle shape and configuration analysis by transmission electron tomography
(Journal of Microscopy, Oxford, 2008)
Tomographic reconstruction by transmission electron microscopy is used to reveal three-dimensional nanoparticle shapes and the stacking configurations of nanoparticle ensembles. Reconstructions are generated from bright-field ...
Particle size analysis: (90)Y and (99m)Tc-labelled colloids
(Journal of Microscopy, Oxford, 2008)
Colloidal particle size is an important characteristic to consider when choosing a radiopharmaceutical for diagnosis and therapeutic purposes in nuclear medicine. Photon correlation spectroscopy (PCS) and transmission ...
Investigation of properties of electrochemically synthesizediron oxide nano-powders
(Journal of Microscopy, Oxford, 2008)
Nano-sized powders of iron oxides have been synthesized electrochemically at temperatures in the range of 295-361 K, and current densities in the range of 200-1000 mA dm(-2). The structure and morphology of the powders ...
Surface roughness of ultra-thin silver films sputter depositedon a glass
(Journal of Microscopy, Oxford, 2008)
Silver was sputter deposited on a glass with a thin film thickness ranging from 10 to 80 nm. Scanning tunnelling microscopy was used to study the morphology of the obtained Ag-glass surfaces and to estimate the surface ...
Hydrogen storage properties of MgH(2)-diatomite composites obtained by high-energy ball milling
(Journal of Microscopy, Oxford, 2008)
To investigate the effects of specific porous microstructure of diatomite on the hydrogen storage properties of MgH(2), a two-step preparation was carried out. The first step was decrepitation of MgH(2) particle size during ...
Modelling and experimental investigations of thin filmsof Mg phosphorus-doped tungsten bronzes obtainedby ultrasonic spray pyrolysis
(Journal of Microscopy, Oxford, 2008)
In this study, the synthesis of thin films of Mg phosphorus doped tungsten bronzes (MgPTB; MgHPW(12)O(40).29H(2)O) by the self-assembly of nano-structured particles of MgPTB obtained using the ultrasonic spray pyrolysis ...
Effects of the Ar ions pre-amorphization of Si substrateon interface mixing of Fe/Si bilayers
(Journal of Microscopy, Oxford, 2008)
Ion beam mixing of Fe/Si bilayers, induced by 100 keV (40)Arions at room temperature was investigated. Rutherford backscattering spectroscopy (RBS), atomic force microscopy (AFM), scanning electron microscopy (SEM) and ...
Photothermal microscopy: a step from thermal wave visualization to spatially localized thermal analysis
(Journal of Microscopy, Oxford, 2008)
The calculation of photothermal response detected by a photothermal microscope is presented. By using a technique based on Greens functions and integral transforms, a model for laser-induced temperature distribution functions ...
Moisture and gamma-ray irradiation effects on the mechanical properties of carbon fibre-reinforced plastics
(Journal of Microscopy, Oxford, 2008)
The effects of gamma-irradiation and moisture absorption on the mechanical properties of carbon fibres-epoxy resin composites were studied. The properties dominated by the matrix and fibre-matrix interface (interlaminar ...
