Measuring the specific surface area of snow with X-ray tomography and gas adsorption: comparison and implications for surface smoothness

Autor: M. Kerbrat, B. Pinzer, T. Huthwelker, H. W. Gäggeler, M. Ammann, M. Schneebeli

Publikováno v: Atmospheric Chemistry and Physics, Vol 8, Iss 5, Pp 1261-1275 (2008)

Chemical and physical processes, such as heterogeneous chemical reactions, light scattering, and metamorphism occur in the natural snowpack. To model these processes in the snowpack, the specific surface area (SSA) is a key parameter. In this study,

During its first four years of life, the TOMCAT beamline [1] at the Swiss Light Source has established itself as a state‐of‐the art hard x‐ray tomographic microscopy endstation for experiments on a large variety of samples, ranging from the fie

Artifacts in X-ray Dark-Field Tomography

Autor: P. Modregger, Z. Wang, T. Thuering, B. Pinzer, M. Stampanoni, Ian McNulty, Catherine Eyberger, Barry Lai

Publikováno v: AIP Conference Proceedings.

Grating‐based x‐ray imaging provides three principle kinds of contrast: absorption, phase, and dark‐field. Due to the availability of tomographic reconstruction algorithms for the dark‐field contrast, it is now possible to take advantage of q

Tomographic Hard X-ray Phase Contrast Micro- and Nano-imaging at TOMCAT

Autor: M. Stampanoni, F. Marone, P. Modregger, B. Pinzer, T. Thüring, J. Vila-Comamala, C. David, R. Mokso, Karen K. W. Siu

Publikováno v: AIP Conference Proceedings.

This article illustrates the phase contrast instrumentation installed at the Tomographic Microscopy and Coherent Radiology beamline (TOMCAT) of the Swiss Light Source. Our experimental framework has been designed to extract phase information at spati

Stimulation of 25(OH)D3-Serum Level by Minimized UV-Exposures of Different Sunbed Lamps in Winter Time

Autor: P. Bocionek, B. Pinzer, Bodo Lehmann, Peter Knuschke, Michael Meurer

Publikováno v: Biologic Effects of Light 1998 ISBN: 9781461372967

In Dresden (51°N) the 25(OH)D3-serum levels in residents of nursing homes and of an old people’s home ranged below the lower border (≤10 ng/ml). A comparison to young healthy persons resulted in reduced serum levels, too (December: 14.9 ± 4.2 n

[Therapy of psoriasis with the Philips TL-01 ultraviolet lamp]

Autor: J, Barth, B, Pinzer

Publikováno v: Dermatologische Monatschrift. 176(11)

22 patients suffering from exanthematic psoriasis were irradiated with the UV-lamps UVS 65-2 (Narva, Brand-Erbisdorf) or TL-01 (Philips Company, Eindhoven, Niederlande) respectively. The latter one emits a narrow-band UV-spectrum at 311 nm which seem

[Photoallergic contact eczema caused by 4-isopropyldibenzoylmethane]

Autor: H, Jacobi, B, Pinzer

Publikováno v: Dermatologische Monatschrift. 176(11)

Dibenzoylmethanes are widely used in UVA absorbing sunscreens but also in cosmetics protecting against skin aging. We report on a 25 years old female with photoallergic contact dermatitis caused by 4-Isopropyl-dibenzoylmethane (Eusolex 8020, Merck),
