AB  - Saglasnost teorije i eksperimenata eksplozivnih procesa pripada kategorijama kod kojih se traži visoka pouzdanost. Eksperimenti sa daljinskom kontrolom ili izazivanjem detonacionih procesa predstavljaju jednu od oblasti u kojoj se primenom optičkih metoda može da smanji rizik povezan sa ljudskim faktorom. Simulacije dinamike kad će pojedini zaštitini materijal da dostigne kritične parametre donose razne aproksimacije. U zavisnosti od primene bira se strožiji kriterijum. U radu je data analiza nekih primena lasera u svrhe eksplozivih procesa. Daće se aspekti preplitanja odnosa laser-eksplozivni proces sa nekoliko strana. Analiziraće se neki softverski paketi, kojima se modeluju procesi u kojima laser dovodi do promene temperature lokalnog suda sa eksplozivnim materijalom. Izborom osnovnih jednačina jednog prilaza daju se rezultati temperaturnih polja. Proračun može da posluži kao metod za modelovanje i nalaženje potrebnih uslova rada lasera za obezbeđenje eksplozivnog procesa.
AB  - The agreement between theory and experiments of explosive processes belongs to a category at which the high reliability is needed. Experiments with remote control and initiation of detonation processes represent such field in which the risk for human factor could be decreased if optical methods are applied. Simulations in dynamics of reaching the critical parameters for different protective materials bring a various approximations. Depending from the application, the stronger criteria could be chosen. The application of some lasers for an explosive process is analyzed in this paper. The interrelations between laser-explosive process will be analyzed from a few sides. Some software packages, for modeling the processes in which the laser brings temperature changes into the container with an explosive material, will be critically analyzed. By choosing the principal equations in one approach, the results of temperature field distribution are given. This calculation may serve as method for modeling and finding the needed conditions of laser action for successful providing an explosive process.

AB  - The investigated nanometric magnetite powders were synthesized electrochemically, and examined by XRD and SEM techniques. Their reduction was conducted through the isothermal heating in hydrogen in the temperature range from 600 to 860 K. Kinetics of the hydrogen recovery process during oxidation of freshly formed Fe powders in a water vapor stream was also studied. It was assumed that the solid-gas reaction is diffusion controlled, and Janders model was applied to describe it. The experimental data suggest that the reoxidation process proceeds in two stages, at various activation energies. By changing the conditions of the electrochemical (EC) process we were able to produce the iron oxide powders with optimal particle size and activity, for pure hydrogen production through appropriate reduction/oxidation processes.

AB  - Magnetic iron oxide nano-powders were synthesised electrochemically, using a low-carbon steel electrode immersed in a NaCl aqueous solution, at constant temperature of the electrolyte, pH and current density. In the second step, portions of the starting admixture were boiled at 360 K during two hours and autoclaved at various temperatures. Both the starting powder and the treated ones were. examined by a standard XRD method, then uniaxially pressed into pellets under 400 MPa, and their electric and magnetic behaviour during non isothermal heating was analysed.
