Generation of X-Rays at Bubble Cavitation in a Fast Liquid Jet in Dielectric Channels

The paper presents the results of studying the combined shock-wave radiation-emission processes associated with cavitation phenomena that occur at fast directional motion of a liquid jet into a closed working chamber through narrow dielectric channels. These processes induce high-power tunable X-ray radiation outside the chamber. At a relatively small liquid pressure, cavitation has been shown to generate shock waves in the chamber walls, which excites surface atoms and leads to the emission of X-rays from the outer surface of the chamber. At a high liquid pressure, the liquid jet does not touch the chamber walls and the cavitational shock waves lead to the excitation of the surface atoms of the jet itself accompanied by the generation of optical and X-ray radiation in the jet, which has been also observed in experiments.

Effect of drying temperature on sizes and morphology of goethite nanoparticles

The morphology, structure, and size distribution of goethite nanoparticles, which are obtained by chemical precipitation of iron salt and alkali in aqueous solutions with different surfactants and are dried at 100°C and room temperature, have been investigated in order to develop technology for obtaining goethite (α-FeOOH) nanoparticles of minimum sizes. It is found that the samples dried at a temperature of 100°C have a different phase state and increased sizes as compared to the samples dried at room temperature.

Shock-cavitational mechanism of X-ray generation during fast water stream cavitation

The process of generation of X-ray radiation formed during the free exit of a fast stream of water in a state of cavitation from a narrow channel was investigated both experimentally and theoretically. It was observed for the first time that the initial part of the stream and the outlet of the channel are the sources of intensive X-ray radiation (with an activity of 0.1 Cu), which is connected with the cavitation phenomena and the following excitation of shock waves. The frequency of the X-ray radiation depends on the composition of the radiating surface (water or the surface of the channel walls) and increases with the increase of the atomic number of the surface. The mechanism of radiation generation is connected with the influence of cavitation shock waves formed on the nearest interface (water-air, water-metal, metal-air, air-metal, etc.).

Dielectric properties of colemanite

Rapid cooling of colemanite crystals is shown to create a metastable state with a number of unusual anomalies in dielectric properties. The dielectric properties of colemanite show a significant thermal hysteresis. A number of parameters are calculated, and the origins of the observed anomalies are discussed.

Investigation of Physical Properties of MRET Activated Water and its Successful Application for Prophylaxis and Treatment of Oncology

The results of investigation of the effect of water, activated by nonionizing Molecular Resonance Effect Technology (MRET), on prophylaxis and treatment of two kinds of oncology diseases of mice are presented. It was discovered in detailed experiments that under the action of this activator there are very essential modifications of the basic physical-molecular properties of distilled water (decrease of viscosities, electrical conductivity and permittivity by several times, sharp increasing or oscillation of pH exponent etc.).

On the phenomenon of oscillatory decay of the 125mTe isomer

The radioactive decay curve of the 125mTe nucleus is measured in the environment of stable 125Te nuclei representing a Mössbauer resonant screen. Thorough analysis shows that the decay of the 125mTe nucleus corresponds to the standard exponential law with half-life T1/2≈58 days without oscillations.

Molecular mechanisms and time-dependent dynamics of hormesis, antagonism and radioprotective effects at combined ionizing irradiation of biological systems

Abstract We study the time-dependent dynamics of formation, relaxation and self-reparation of DNA double-strand breaks at combined irradiation and the nonradiation degradation processes. The self-repairing process of DNA double-strand breaks is related with the peculiarities of long-range interaction of nucleotides within the breakage area. The properties of an intracellular liquid and the characteristics of the long-range interaction between the end pairs of nucleotides in the area of DNA double-strand break are changed during irradiation. Each kind of irradiation is characterized by certain effectiveness of double-strand breaks formation but on the other hand, the irradiation creates the conditions for their liquidation. Based on the analysis and correlation of these phenomena the time-dependent theory for DNA degradation was created, including hormesis phenomenon, radiation antagonism, the validity of anomaly influence of low and large doses at sharp and chronic irradiation and other effects. A qualitative and quantitative agreement of the theory and experimental results was obtained.

DETECTION AND INVESTIGATION OF ANOMALOUS (UNDAMPED) THERMAL WAVES

Results of the detection and study of fundamentally new physical phenomenon generating undamped temperature waves, which can exist in different environments only at certain frequencies, the value of which depends on the time of the local relaxation of thermal excitations in these environments (the thermalization time) are presented. In the air, under normal conditions, the minimal frequency of such wave corresponds to 70-90 MHz and in metals and semiconductors it is 10121014 Hz. In the experiments these waves are generated via cavitation processes and registered in the air at a distance of 2 m and this distance is limited only by the experimental conditions
