Opis:
Soft X-ray microscopy has great advantages over other types of microscopy on the observation of hydrated specimens at high spatial resolution below 100 nm, and on the elemental and molecular mapping using absorption characteristics. These advantages are particularly suitable for biomedical applications. A possible problem associated with observation of specimens at high spatial resolution in a hydrated environment is described and a strategy to overcome the problem is presented. The latter part of the present report deals with spectromicroscopy to obtain molecular distribution in biological specimens. DNA and protein distributions in isolated nuclei are examined following to the progression of apoptosis at high resolution, and the oxidation product is visualized in human hair in relation to calcium content.

Opis:
The positron annihilation lifetime technique can be applied to the study of the sorption mechanism in polymers in a quite unique way. In our previous experiments it had been shown that τ$\text{}_{3}$ and I$\text{}_{3}$ of polymers show a V-shaped dependence as a function of the contact with vapors. The decreasing part of the V-shaped dependence had been attributed to the Langmuir-type sorption, and the increasing part to delayed occurrence of the Henry-type sorption. But since there was some doubt that a capillary effect, i.e. the vapor to be sorbed is deposited in between the polymer membranes, might be involved in the increasing part, we performed a careful experiment to avoid the capillary effect. We have performed further experiments in a careful condition to avoid the capillary effect, and have observed the same V-shape as before. Thus our interpretation of the V-shaped dependence has been established. Furthermore, in another example it is shown a case where the capillary effect is observed. This latter case is an example how positron annihilation lifetime can distinguish the real sorption and false sorption (capillary effect).

Opis:
We investigated the magnetic properties of chalcogenide-spinel superconductor CuRh₂S₄ under pressure and estimated the pressure dependence of the superconducting parameters. With increasing pressure, the superconducting transition temperature (T_{c}), thermodynamic critical field (H_{c}), upper critical field (H_{c2}), penetration depth (λ), and GL parameter (κ) increase. Meanwhile, the lower critical field (H_{c1}) is unchanged and the Ginzburg-Landau coherence length (ξ_{GL}) is reduced by pressurization. The increasing value of κ indicates enhanced characteristics of the type-II superconductor CuRh₂S₄.
