The radiation-induced chemistry in solid xenon matrices

The paper presents an overview of recent studies on the radiation-chemical transformations of guest molecules in solid xenon induced by fast electrons and x-ray irradiation. Specific features of the experimental approach based on combination of matrix isolation IR and EPR spectroscopy are briefly outlined (with particular impact on using monoisotopic and isotopically enriched xenon matrices). The results reveal rich and diverse radiation-induced chemistry in solid xenon, which is considered in the following major aspects: (1) matrix-induced and matrix assisted transformations of the primary guest radical cations; (2) production and dynamics of hydrogen atoms; (3) formation of xenon hydrides. Finally, preliminary results on the radiation-induced generation of oxygen atoms and ions in solid xenon are presented

Reducing the risk of collision of vehicles

In order to clarify the method of determining the value of the braking distance to determine the maximum deceleration of the vehicle by braking all wheels ATS when using the differential equation of motion of the car was removed dependence, which more precisely characterizes the size of tor brake way. Approximation of existing dependencies, obtained by the authors of theoretical and experimental researches allows to make a comparative analysis of the results determine the stopping distance of a PBX depending on its velocity before braking. The offered technique allows to take into account the factors of road conditions the operation of the exchange that affect the risk of collision and reduce injuries to drivers
