Over the last fifteen years, there has been a rapid growth in the use of high resolution X-raycomputed tomography (HRXCT) imaging in material science applications. We use it atnanoscale resolutions up to 50 nm (nano-CT) for key research problems in large scale operationof polymer electrolyte membrane fuel cells (PEMFC) and lithium-ion (Li-ion) batteries inautomotive applications...

Hollow magnetic porous Fe(3)O(4)/α-FeOOH microspheres, with abundant surface hydroxyl groups and carbonate-like species, were prepared using a simple template free solution method. The obtained magnetic microspheres were characterized by field emission scanning electron microscopy, transmission electron microscopy, nitrogen adsorption-desorption isotherms, vibrating sample magnetometry and X-ra...

The effects of X-ray and carbon ion irradiation on DNA and genes in head and neck carcinoma cells were examined. Four head and neck cancer cell lines (squamous cell carcinoma, salivary gland cancer, malignant melanoma, normal keratinocyte) were treated with 1, 4, and 7 GyE of carbon ion, or 1, 4, and 8 Gy of X-ray, respectively. DNA and RNA in the treated cells were extracted and purified. PCR-...

PURPOSE In 1992, Georges Charpak invented a new type of X-ray detector, which in turn led to the development of the EOS(®) 2D/3D imaging system. This system takes simultaneous anteroposterior and lateral 2D images of the whole body and can be utilized to perform 3D reconstruction based on statistical models. The purpose of this review is to present the state of the art for this EOS(®) imaging t...

Co-doped TiO2 nanoparticles containing 0.0085, 0.017, 0.0255, 0.034, and 0.085 mol % Co(III) ion dopant were synthesized via sol-gel and dip-coating techniques. The effects of metal ion doping on the transformation of anatase to the rutile phase have been investigated. Several analytical tools, such as X-ray diffraction (XRD), transmission electron microscope (TEM), X-ray photoelectron spectros...

Two approaches for metal ion incorporation were employed to introduce Ca2+ into SBA-15; Direct Synthesis (DS) and Wet Impregnation (WI). The non-ionic template was removed by two different methods; calcination and solvent extraction. The obtained catalysts were characterized by means of X-Ray Powder Diffraction (XRD), Energy Dispersive X-ray (EDX), and FT-IR spectroscopy. The bas...

Surface modification of different materials exposed to an environment typical for hot cathode ionisation vacuum gauges was investigated. Such has been generated in a specially designed setup which simulates conditions Bayard-Alpert gauge. Characterisations by means X-ray photoelectron spectroscopy and work function study have performed before after the sample exposure Ar H2 gas discharges. The ...

X-ray nanotomography has developed into a powerful new tool for three-dimensional structural analysis. The scanning approach offers capabilities that are competitive with full-field imaging. Current and ultimate limitations of nanotomography are examined in light of recent work.
