Opis:
Studies on the use of energetic ion beams for material modification have been initiated originally within the Manhattan project and have been continuously developed since then. The consecutive steps were devoted to the studies of ion implantation into semiconductors, metals, ceramics and, most recently, organic materials. One of the latest areas of applications is modification of elastomers, commonly known as rubbers. In the present paper the results of the studies on structural and functional properties of irradiated elastomers will be presented with the special emphasis on the materials used in aviation and military applications. Among the structural modifications, a massive loss of hydrogen atoms appears as the most peculiar characteristic of irradiated elastomers. Functional properties of irradiated rubbers: microhardness and friction coefficient, will be presented and application potential of the materials discussed.

Opis:
W pracy opisano procedury symulacji Monte Carlo procesu rozpraszania wstecznego w kryształach zawierających dyslokacje. Sigmoidalny kształt ugiętych rzędów (płaszczyzn) atomowych można przybliżyć funkcją arctan, co stanowi model dystorsji sieci krystalicznej w pobliżu półpłaszczyzny dyslokacji krawędziowej. Badania strukturalne kryształów AlGaN i SrTiO3 za pomocą HRTEM pozwoliły wyznaczyć parametry geometryczne zaburzeń sieci krystalicznej w sąsiedztwie dyslokacji (kąt ugięcia w punkcie przegięcia funkcji arctan oraz odległość między jej asymptotami). Zależność każdego z tych parametrów od odległości od krawędzi dyslokacji można przybliżyć funkcją ekspotencjalnego zaniku i wyznaczyć współczynniki tej funkcji. Dane te zostały wykorzystane w symulacjach Monte Carlo widm rozpraszania wstecznego AlGaN oraz SrTiO3 i pozwoliły na ilościową parametryzację rozkładu dyslokacji w defektowanych kryształach.
A procedure of Monte Carlo simulation of a backscattering process in crystals containing dislocations was described in this publication. Sigmoidally bent atomic rows (planes) can be approximated by an arctan function being a model of the lattice distortion in the vicinity of a dislocation. HRTEM analysis of AlGaN and SrTiO3 crystals allowed determination of the geometrical parameters of crystalline structure distortion in the vicinity of a dislocation (a bending angle at the inflexion point of the arctan function as well as the distance between its asymptotes). A dependence of each of these parameters on the distance from a dislocation edge can be approximated by an exponential decay function. The parameters of this function can be calculated from the experimental data. The parameters obtained were used in Monte Carlo simulation of the backscattering process in AlGaN and SrTiO3 and enabled quantitative determination of the depth distribution of dislocations in defected crystals.

Opis:
Ceramics are key engineering materials in many industrial domains. The evaluation of radiation damage in ceramics placed in a radiative environment is a challenging problem for electronic, space and nuclear industries. Ion beams delivered by various types of accelerators are very efficient tools to simulate the interactions involved during the slowing-down of energetic particles. This article presents a review of the radiation effects occurring in nuclear ceramics, with an emphasis on new results concerning the damage build-up. Ions with energies in the keV-GeV range are considered for this study in order to explore both regimes of nuclear collisions (at low energy) and electronic excitations (at high energy). The recovery, by electronic excitation, of the damage created by ballistic collisions (swift heavy ion beam induced epitaxial recrystallization process) is also reported.

Opis:
We studied narrow (submicron) constrictions in the layers of ferromagnetic semiconductor (Ga,Mn)As. We have demonstrated a contribution of the quantum localization effects to the magnetoresistance of the constricted samples. We have also found a negative contribution of a domain wall trapped in the constriction to the resistance, due presumably to the erasing of the localization effects by the domain wall.

Opis:
The influence of the size of crystalline regions on mechanical properties of irradiated oxides has been studied using a magnesium aluminate spinel $MgAl_2O_4$. The samples characterized by different dimensions of crystalline domains, varying from sintered ceramics with grains of few micrometers in size up to single crystals, were used in the experiments. The samples were irradiated at room temperature with 320 keV $Ar^{2+}$ ions up to fluences reaching 5 × $10^{16} cm^{-2}$. Nanomechanical properties (nanohardness and Young's modulus) were measured by using a nanoindentation technique and the resistance to crack formation by measurement of the total crack lengths made by the Vickers indenter. The results revealed several effects: correlation of nanohardness evolution with the level of accumulated damage, radiation-induced hardness increase in grain-boundary region and significant improvement of material resistance to crack formation. This last effect is especially surprising as the typical depth of cracks formed by Vickers indenter in unirradiated material exceeds several tens of micrometers, i.e. is more than hundred times larger than the thickness of the modified layer.

Opis:
The influence of $He^+$ ion bombardment on magnetoresistance, magnetization reversal and domain structure of sputtered $(Ni_{80}Fe_{20}(2 nm)//Au(2 nm)//Co(0.6 nm)//Au(2 nm))_{10}$ multilayers was investigated. The samples were bombarded using $He^+$(30 keV) ions with fluences D varied from $10^{13}$ to 3×$10^{16}$ $He^+$/$cm^{2}$. With increasing D the following changes in magnetic properties were observed: (i) exponential decay of the saturation field of Co layers, (ii) progressive decrease in magnetoresistance as a result of degradation of Co layers perpendicular anisotropy, (iii) linear decrease in stripe domain period with log(D).

Opis:
A model of dislocations has been developed for the use in Monte Carlo simulations of ion channeling spectra obtained for defected crystals. High resolution transmission electron microscopy micrographs show that the dominant type of defects in the majority of ion irradiated crystals are dislocations. The RBS/channeling spectrum is then composed of two components: one is due to direct scattering on randomly displaced atoms and the second one is related to beam defocussing on dislocations, which produce predominantly crystal lattice distortions, i.e. bent channels. In order to provide a correct analysis of backscattering spectra for the crystals containing dislocations we have modified the existing Monte Carlo simulation code "McChasy". A new version of the code has been developed by implementing dislocations on the basis of the Peierls-Nabarro model. Parameters of the model have been determined from the high resolution transmission electron microscopy data. The newly developed method has been used to study the Ar-ion bombarded $SrTiO_3$ samples. The best fit to the Rutherford backscattering/channeling spectra has been obtained by optimizing the linear combination of two kinds of defects: displaced atoms and bent channels. The great virtue of the Monte Carlo simulation is that unlike a traditional dechanneling analysis it allows quantitative analysis of crystals containing a mixture of different types of defects.

Opis:
On the 28th of June 2017, the Polish Ministry of the Environment announced the boundaries of the tender areas selected for the third licensing round for concessions for prospection, exploration and exploitation of hydrocarbons. This round is going to be proceeded in the 4th Quarter of 2018 and 1st Quarter of 2019. The geologists of the Polish Geological Survey selected 15 tender areas (promising for discoveries of conventional and unconventional oil and gas fields) based on the geological data resources stored in the National Geological Archive, other published data, as well as the knowledge and experience of employees of the Polish Geological Institute - National Research Institute and the Polish Ministry of the Environment. All selected areas are located onshore. In this article we describe 10 tender areas located in the Gdańsk, Pomerania and Wielkopolska petroleum provinces. Other tender areas situated in the Carpathians (Błażowa, Proszowice W, Rudnik-Lipiny, Wetlina) and in the Lublin Petroleum Province (Ryki) will be discussed in the next publication. Three areas: Wejherowo, Bytów and Braniewo-Miłakowo are located in the northern Poland (Gdańsk Petroleum Province). The exploration targets of these areas are generally related to structural-lithological traps in the Middle Cambrian beds of the Baltic Basin, as well as to unconventional shale oil and gas in the Lower Paleozoic. Seven tender areas are situated in the northwestern Poland (Pomerania and Wielkopolska Petroleum Provinces). Three of them - Chodzież, Piła and Leszno are dedicated to conventional gas deposits in the Rotliegend sandstones and, in some cases, also oil deposits in the Zechstein/Main Dolomite. Excluding the Leszno tender area, chances for tight gas discoveries exist within the Rotliegend sandstones. The exploration target of the Konin tender area is related to possible conventional fields in the Jurassic and Lower Cretaceous beds. In the Pomerania region the exploration target is generally related to conventional hydrocarbon deposits in the Devonian, Carboniferous and Permian (Rotliegend and Zechstein/Main Dolomite). Three tender areas are situated within the region of: Sierpowo, Orle and Chełmno. As a rule, a concession is granted for a period of 10 to 30 years and is divided into 2 phases: 1) prospecting and exploration phase (which lasts from 4 to 5 years and can be extended to another 2-year period), 2) production phase. Every entity interested in obtaining a concession needs to undergo the qualification procedure. We believe that this publication will contribute to better understanding of the offered tender areas and encourage activity in the Polish oil and gas sector.
