Energy conversion efficiency in betavoltaic cells based on the diamond Schottky diode with a thin drift layer.

The HPHT diamond Schottky diode was assembled as a Metal/Intrinsic/p-doped structure betavoltaic cell (BC) with a very thin (1 μm) drift layer and tested under 5-30 keV electron beam irradiation using a scanning electron microscope (SEM). The effect of the β-radiation energy and the backscattering of electrons on the energy conversion was studied. From the results obtained, it is shown that, the efficiency of the investigated BC increases from 1.

Atomically resolved STM imaging with a diamond tip: simulation and experiment.

The spatial resolution of a scanning tunneling microscope (STM) can be enhanced using light element-terminated probes with spatially localized electron orbitals at the apex atom. Conductive diamond probes can provide carbon atomic orbitals suitable for STM imaging with sub-Ångström lateral resolution and high apex stability crucial for the small tunneling gaps necessary for high-resolution experiments. Here we demonstrate that high spatial resolution can be achieved in STM experiments with single-crystal diamond tips, which are generally only considered for use as probes for atomic force microscopy.

[Specific features of the therapy of patients with hepatitis B and C in the presence of accompanying cryoglobulinemia].

Correlation between the presence of cryoglobulinemia and delayed convalescence in patients with acute viral hepatitis B and C has been studied. It is established that cryoglobulinaemia is more frequent in patients with long-term hepatitis C virus RNA replication (and anti-HCV IgM in the blood), than in cases where anti-HCV IgM disappeared from blood serum within the first month of antiviral treatment. The results of cycloferon, amixin, and isoprinosin administration in patients with acute viral hepatitis B and C have been analyzed.

[Plasma technologies in treatment of purulent wounds].

The article is devoted to using plasma flow for treatment of purulent wounds. The authors have shown an anti-inflammatory, antibacterial, stimulating effect of plasma radiation on the basis of clinical methods of control of the wound process in 143 patients (hypothermia, pain syndrome in rest, the presence of purulent discharge, edema, granulation tissue).
