«Molecular Energy Concept of Substances Unpacking»

Download an article

This article brings together previously published evidence of the unified nature of physical processes and phenomena in terms of changes in the energy of a substance molecule. The unified physical nature of all these physical phenomena has been proven, as a single multistage process of energetic unpacking of molecules of a substance, which is logical to call the molecular-energy concept of unpacking a substance. The considered processes include the following processes. Surface rupture, characterized by the surface tension coefficient. The melting process of a substance characterized by its melting point. A boiling process characterized by the boiling point. Evaporation (and condensation) process characterized by internal energy and enthalpy as well as critical point. The conclusions of the theory are confirmed by well-known empirical dependences and by reference books of the physical properties of simple substances: internal energy, enthalpy, surface tension, melting point, boiling point and critical point.

«Physical findings. Matter is one of the states of radiated energy»

Download an article

According to the author “atom” is a microsystem. The ability of photons (γνc – “nucleon”) to rotate at the speed of light in the microsystem (atom) ring – through – ring reveals the cause of inorganic matter formation. Gravity is a total apogee of the rotation of nucleons γνc in the microsystems (atoms). The article shows the new energy technologies instead of nuclear power and hydrocarbons, and their main aim which is the hydrogen energy radiation. The researcher notes that the speed of space journey can become relatively similar to the speed of light.

«Main Approaches to Damage Assesment from Hazardous Processes (On the Example of the Central Federal District)»

Download an article

This article discusses the manifestation of dangerous hydrometeorological processes in the Central Federal district. The analysis of manifestation dynamics of these dangers is carried out. The dependences of the hazardous processes cases number in general and by categories of on the temperature regime consequences are considered in the article. It was found out that within areas where average annual temperature exceeds annual temperature in the Central Federal district the number of hurricanes and heavy rains exceeds the average value, and the number of cases leading to negative consequences associated with blizzards and snowfall well below their average long-term manifestations, but the number of floods above their average values. The algorithm of calculation of forecast economic damages from manifestation of hydrometeorological dangers is offered.

«Experimental study of the density distribution of the particles of the material in screw installation»

Download an article

The experimental studies of density distribution of the particles of a mixture of wheat, oats, rye to feed pigs by infrared heating at the time of stay and temperature at the exit of the installation. The purpose of the work is to study the quality of treatment of the product with the settings with the screw and the screw with installed round jumper on the pen of the screw. Screw installations with infrared emitters of selected wavelength give the opportunity for intense and continuous heat treatment process. The authors used the optimal parameters of the process with the screw and the screw with installed round jumper on the pen of the screw. The parameters of screw installation during the study were the following: the number of revolutions of the screw was 10 rpm, density of heat flux was 12 kW/m2, output capacity – 250 kg/h.

«Interconnection between melting, boiling and critical points»

Download an article

We received theoretical formulas of the interconnection between melting, boiling and critical temperatures. Uniform physical representation of melting, boiling and evaporation processes was the basis for deriving the formula of interconnection between them. We use the concept of the material substance internal energy in terms of the molecules “unpacking” idea. The reference manual data on 85 substances from 13 to 855 degrees Kelvin confirms the theoretically derived formulas. We carried out the comparison of theoretical formulas and experimental data by their mean values. A simple ideal substance model with spherical molecules was considered as a model of substance molecule. The melting point is 1/3, and the boiling point ranges from 1/2 to 2/3 of the critical point for this model.

«Revisiting the friction of high entropy alloys and coatings»

Download an article

In this paper, the authors propose a new approach to the consideration of the friction phenomenon in HEAs and, in particular, dry friction. An equation is obtained that shows the nonlinear dependence of the friction coefficient on Gibbs energy G0, on temperature T, on the concentration of the number of electrons N and which allows predicting the formation of high entropy alloys and coatings.

«Correlation of temperatures of melting and boiling of substances from the hypotheses of unpacking the substance»

Download an article

According to the properties of melting points and boiling points of the elements of the periodic table of D.I. Mendeleyev the application of the unpacking hypothesis of the substance was verified. The article contains the results of the verification. In general, according to the data for 98 substances taken from the information in Internet, convergence of results with an error of up to 40% for 73 substances was obtained. The effect of periodicity on the result is found. An exception to the calculated dependences was obtained for ten substances: noble gas and most halogens. A large discrepancy between the theoretical formulas and the reference data was also caused by the 14 elements of the middle groups.
