Investigating the optical properties of polycrystalline AgCl(1-x)Br(x) (0≤x≤1) and Ag(0.95)Tl(0.05)Br(0.95)I(0.05) for IR engineering.

Using the Michelson technique we measured the refractive indices for the plane-parallel thin plates made of AgClBr(0≤x≤1) and, to the best of our knowledge, for the first time for the AgTlBrI plate, manufactured by hot embossing, at 632.8 nm. We recorded their absorption spectra within the range of 0.

Regenerative life-support system development problems for the Mars mission.

An analysis of expediency of using physicochemical and biotechnological complexes of life-support systems has been performed with reference to the most likely trends of manned cosmonautics development for the nearest decades--orbital stations in the Earth orbit, Moon base, and Mars mission. The analysis results have shown that the physicochemical complex is much more advantageous than the biotechnological one for all cases considered. This conclusion is based on significant difference in power utilization factor: 70-90% for the physicochemical complex and 5-10% for the biotechnological one as far as the photosynthesis efficiency is concerned.

[Effect of the state of graphite surfaces on the activity of immobilized glucose oxidase].

The work deals with immobilization of glucose oxidase on modified graphite. The effect of the carrier surface composition on the major properties of the immobilized enzyme was examined. The level of activity of the immobilized enzyme is shown to depend on the quantity of Ti and Zr oxides applied on the graphite surface.
