    Opis:
    A number of efficient solutions are already in existence today for reducing specific energy and raw material needs, and they are continuously being improved. Since the competition between individual solutions for sustained energy efficiency may prove to be an obstacle to the system as a whole, the interaction of individual elements and sub-systems in complex domains must be considered in an integrated way with an eye to their reciprocal energy effects. What will be the impact of energy savings resulting from innovative approaches and intelligent solutions at a single systemic level on the system as a whole? Do they serve to reduce overall energy costs? What kinds of energy-related information are necessary to answer these questions? This article examines the issue of how dedicated energy savings in the production sector impact on the total energy requirement in factory systems. In one example, process and building are examined together in order to thereby recognize energy relationships. It was demonstrate that waste heat from machine tools has a significant impact on the factory hall climate and therefore on the heating needs of factory buildings. A model calculation demonstrated that energy savings at individual system levels are transferable to the entire system in direct proportion to the energy efficiency of the building.

    Opis:
    This study discusses the technology of coal slime recovery for preparing ultra-clean coal (UCC). X-ray diffraction analysis (XRD) and scanning electron microscopy combined with energy dispersive spectroscopy (SEM-EDS) were used to analyze the characteristics of coal slime and to explore the types of minerals and embedded characteristics of coal slime. The particle interaction energy and contact angle analysis were used to determine the UCC preparation process through dry and wet grinding dissociation comparison and shear flocculation flotation tests, combined with zeta potential measurements. The results showed that the inorganic minerals in the slime were mainly kaolinite clay minerals, which were easy to mud in the pulp and needed grinding. The calculation results of the interaction energy indicated that the interaction force of dry-ground slime in the pulp was small, and flocculation was more likely to occur. The wet-ground product was subjected to three flotations to obtain UCC with an ash content of 0.95%.

    Opis:
    The literature devoted to numerical investigation of adsorption of heavy metal ions on carbon nanotubes is scarce. In this paper molecular dynamics is used to simulate the adsorption process and to investigate the effect of the infl uencing parameters on the rate of adsorption. The predictions of the molecular dynamics simulation show that the adsorption process is improved with increasing the temperature, pH of solution, the mass of nanotubes, and surface modifi cation of CNT using hydroxyl and carboxyl functional groups. The results predicted by the model are compared with the experimental results available in the literature; the close agreement validates the accuracy of the predictions. This study reveals that the water layers around the carbon nanotubes and the interaction energies play important roles in the adsorption process. The study also shows that electrostatic force controls the attraction of zinc ions on the nanotube sidewall.

    Opis:
    A new method to calculate the surface interaction energy of ceramic particles and epoxy resin network was investigated using the Material Studio software solution. Detailed simulations were performed with molecular dynamics (MD) method, using Amorphous Cell module, creating relatively simple surface models of polymer (epoxy resin) and ceramics (Al2O3, SiO2 and SiC). The surface models obtained were used to calculate properties and the surface interaction energy of the materials studied. The computed results are in good agreement with the experimental data, confirming the ability to employ the described simulation method in theoretical evaluation of interaction between various filler or reinforcing materials and the polymer matrix.
    Testowano nową metodę obliczania energii oddziaływań powierzchni cząstek ceramicznych z żywicą epoksydową. Obliczenia wykonywano korzystając z oprogramowania Material Studio. Szczegółowe symulacje prowadzono metodą dynamiki molekularnej (MD) za pomocą modułu Amorphous Cell, tworząc modele powierzchni polimeru (żywicy epoksydowej) imateriału ceramicznego (Al2O3, SiO2 lub SiC). Otrzymane modele posłużyły do obliczeń właściwości oraz energii oddziaływań powierzchni badanych materiałów. Uzyskano dobrą zgodność wyników symulacji zdanymi doświadczalnymi, co potwierdziło możliwość zastosowania opisanej metody symulacji do teoretycznej oceny oddziaływania różnych napełniaczy ceramicznych z matrycą polimerową.

    Opis:
    Among various so-called weak interactions, a halogen bond [8 and references therein] is currently probably one of more explored by researchers. This is due to the fact that it has several properties in common with the hydrogen bonding, and thus, similarly as already well characterised H-bond, it may have a crucial role in different physical, chemical, and biological processes. This bond is formed due to stabilising interactions between a region of positive charge located on a surface of the halogen atom and the other atomic center possessing the electron charge surplus (e.g. a lone pair) [8]. The region of positive charge appears on the halogen atom surface due to deformation of its electron cloud resulting in its ellipsoidal shape with the short axis opposite the covalent bond and the long axis in the perpendicular direction [11]. This results in a particular distribution of local charges on the atomic surface, as shown in Figure 1. As a consequence the halogen atom may exhibit a dual character, acting as either electron charge donor or acceptor, depending on the type of interaction and the direction of the appearing interactomic contact. A good example of such situation is shown in Figure 2. Thus, one may consider the situation when two interactions are formed simultaneously and the halogen atom acts as an electron charge donor and acceptor at the same time. For such situation the synergism of both interactions may strengthen complexation. In order to analyze that case, various representative complexes were investigated [13, 17, 18, 20, 21] by means of many-body interaction approach [5, 6]. In general, it appears that as distinct to hydrogen bond [2–4], the synergism is rather weak, with some exceptions for iodine atom due to stronger halogen bonds formed by that atomic centre [13, 17, 18]. In the case of halo-amine tetramers [21] the additional stabilising effect derived from back bonding of π type was found – for the first time for a halogen bond.

    Opis:
    By modifying Ghahramany’s integrated nuclear binding energy formula with strong and weak interaction features, it is possible to approximate nuclear binding energy of isotopes with one unique energy coefficient and four terms. Considering even-odd corrections, shell corrections and other microscopic corrections, it seems possible to improve the accuracy. Based on our recent work and the proposed formulae, we are very confident to say that, quark structure helps in increasing nuclear binding energy and electroweak interaction helps in reducing nuclear binding energy.

We have theoretically investigated phase transition pressures and volume collapses of KH and NaH at high temperatures, and found results well suited with available experimental data. The elastic constants and their pressure derivatives are reported first time. The thermodynamical properties of B₁ phase of KH and NaH are also predicted. The inclusion of temperature effect in TBIP makes the present model realistic and suitable for theoretical high-pressure studies.

    Opis:
    It is known that nano- and micromechanics require new approaches to right describing of surface-like phenomena which lead to an enhanced energy conversion. In this work, a general form of surface forces that consist of a contribution from both the friction and mobility components has been extended to collect the effects of bulk and surface motion of a fluid. Quite similar impact can be observed for a solid-fluid mixture, where the principle of effective stress for this new type of approach should be considered from the very beginning. The second motivation of our work is to present the multiscale domain of fluid-solid interaction which describes some “emergence effects” for materials with especially high volumetric surface densities.

    Studies of the energy deposition by plasma jets incident on a material surface are of topical interest for both the fusion and plasma technology applications. In this paper the results are reported of a comparative study of plasma energy deposition on different material surfaces exposed to plasma jets of various duration and energy density, generated using the QSPA Kh-50 and the MPC devices. The spatial distribution of plasma energy density and the heat load on the surface were measured with a movable calorimeter. The measurements demonstrate that in the case of an exposure to QSPA plasma jets the absorbed heat load is approximately equal to 55-60% of the energy in the incident plasma jet. In the case of plasma jets generated using the MPC device the heat load on the target surface and was practically the same as for the QSPA jets, and additional shielding effects were found to be negligible due to the short duration of plasma jets.

    Opis:
    A review of the results received in the course of fulfillment of the International Atomic Energy Agency Co-ordinated Research Project “Dense Magnetized Plasma” for the last 3 years is presented. Niche of the plasma type within the plasma physics field is outlined. Efforts of the CRP participants concentrated on design and operation of new Dense Magnetized Plasma devices are described. All of them designed for plasma heating and for other applications mainly based on the interaction of radiations generated by the devices with different objects. Materials exploitable, diagnostics of the interaction processes, as well as analytical equipment used by the participants to process the irradiated targets are described. Works developed in the frame of the CRP are covered thermonuclear fusion applications, fundamental plasma physics and material science issues, medicine, biology, and some other spheres. New data on the interaction of the radiations generated in this apparatus with various materials are given. E.g. it was found that the necessary dose producing activation/inactivation of enzymes can be much lower if used at a high-power flux density in comparison with those received with classical sources. All these experiments are discussed in the framework of pulsed radiation chemistry in its perfect sense thereto the criteria are formulated. New foreseen applications of DMP devices mainly based on neutron radiation are proposed and discussed.

    Opis:
    A non-electromagnetic theory of light is proposed, according to which the light-bearing medium is non-baryonic (unstructured) matter as the main component of the substance of the universe. The theory is based on available data on the existence in the intergalactic medium of closed density waves, which are combined into structural elements (particles) of baryonic matter. On the basis of the principle of the equivalence of mass and energy, and also of the theory of waves, the basic relations between the parameters of non-baryonic matter are derived and the possibility of the appearance of running waves in it that make it visible is shown. The unity of the properties of non-baryonic matter with ether is emphasized, and the absence in the theory of contradictions inherent in the electromagnetic concept of light. Experimental evidence of the proposed theory is presented and new approaches to a number of difficultly explainable phenomena, including levitation, are discussed.

For this purpose, a linearized mathematical model of this modified hybrid single-machine infinite-bus (SMIB) power system is developed to analyze the physical mechanism of the SSSC in suppressing oscillations and the influence on the dynamic stability characteristics of synchronization. Typical impacting factors such as the series compensation level, the SOFC penetration and tie-line power are considered in the SMIB and two-area systems. The impact of dynamic interactions on enhancing damping characteristics and improving transient performance of the studied systems is demonstrated using eigenvalue analysis and dynamic time-domain simulations, which validates the validity of the proposed physical mechanism simultaneously.

    Opis:
    Na podstawie równania Laplace'a wyprowadzono zależność między siłą działającą pomiędzy dwoma ziarnami materiału glebowego przez fazę wodną, a składowymi swobodnej energii powierzchniowej. Stwierdzono zależność wartości sił oddziaływań od zawartości Corg w badanych glebach. Dla gleb o zawartości Corg powyżej 40% wartości tych sił są ujemne. Słowa kluczowe: siły adhezji, kąt zwilżania, składowe swobodnej energii powierzchniowej.
    On the basic of Laplace equation the dependence of the force interacting between two soil material particles across the water phase and surface free energy components was concluded.The dependence between interaction force values and organic carbon content C org higher then 40% the values of these forces are negative.
