The features of circuit engineering and results of chip computer simulation which consists of 4-channel operational amplifier (op amp) and 2-channel electrometric voltage follower, designed for pre-processing of sensors signals in high-energy physics are considered. 
The characteristic properties of designed op amp are the absence of current source in the input differential stage and the use of parallel high-frequency channel for increasing of the bandwidth and slew rate.
The results of experimental research that have confirmed the low sensitivity of the parameters of designed integrated circuits created on the field programmable gate array "FGPA-1.3" without the horizontal p-n-p transistors to the influence of gamma-irradiation and electrons with energy of 4 MeV are given.

The titanium dioxide synthesized by an electrochemical method is a perspective material for use in solar elements and catalysts of cleaning of water and air environments. Regularities of electrochemical synthesis of titanium dioxide in glycerin dilute solutions (1:1) in the presence of ammonium fluoride at 2-14 V are investigated. Mathematical scheduling of synthesis process according to plans of first order with use of the complete three-factorial experiment is carried out, the adequate regression equations for formation processes of a titanium dioxide in the field of potentials 8-14 V are received. The electron microscopy method proved porosity of synthesizable layers of titanium dioxide. Water content influence in electrolyte on the speed of electrochemical process and potential size influence on titanium dioxide materials yield is established. It is shown that under the chosen electrolysis conditions electrochemical process is accompanied by the considerable chemical disolution of a titanium. Electrochemical processes in water containing glycerin are investigated by a cyclic voltammetry method. It is established that at electrochemical oxidation of Ti in water containing glycerin (1:1) porous TiO2 with a materials yield no more than 25% is formed.
