The Biała Tarnowska River is a right-bank tributary of Dunajec. It flows from the Low Beskid Mountains, flowing on the border of Ciężkowickie and Rożnowskie foothills and then flows into the Dunajec on the territory of Vistula Lowland (Nizina Nadwiślańska). The aim of this work was to investigate the diatoms diversity…
To combine the low density of magnesium with the corrosion resistance of aluminum in one component, a joint processing has gained scientific interest. It has been shown, that Al-Mg compounds and components with the material combination AlMgSi1/MgAl3Zn can be produced successfully by hydrostatic co-extrusion and forgin…
Production of magnesium components, using high degree of deformation forming process is difficult to achieve without defects, because of low formability of magnesium alloys at room temperature, an approach to a solution was established for developing hot forming process. To simulate hot forming process (bending, deep-…

A facile, environmentally friendly and economical in-situ ion-exchange method was successfully fabricated graphene oxide-based Ag3PO4@AgCl photocatalyst to promote the photocatalytic activity of Ag3PO4@AgCl. The as synthesized GO-Ag3PO4@AgCl composite was characterized by Fourier transform infrared (FTIR), X-ray diffr…
There are two primary challenges associated with assessing the adequacy of a protective structure to resist explosive events: firstly the spatial variation of load acting on a target must be predicted to a sufficient level of accuracy; secondly, the response of the target to this load must also be quantified. When a h…
Well-controlled fine MgTi2O5 powders, with pseudobrookite-type structure, are desired toward various industrial applications, however, commercial powders are hardly available to date. In this study, we focused the processing and characterization of well-controlled MgTi2O5 powders with/without LiF additive. MgCO3 (basi…
Nowadays, the possibility to easy open a food package is of great interest both from the consumer and food producers’ perspective. In this study, the peel/seal properties of poly (ethylene methyl acrylate) (EMA)/polybutene-1 (PB-1) blend films were investigated. Three blends of EMA/PB-1 with different methyl acrylate…
The Louisiana Department of Transportation and Development has seen a rapid decline of low-volume roadway serviceability in recent years as a result of oil and gas exploration within the Fayetteville Shale Play near Shreveport, Louisiana. Similar results are expected on the low-volume roadway network within the Tuscal…
We study electron removal processes in collisions of bare and dressed doubly charged ions with neon atoms in the 20 keV/u to 1 MeV/u impact energy regime. The many-electron problem is represented by a single mean field, which in the case of dressed-ion impact includes the projectile electrons. Moreover, the same basis…
The variation of the niobium (Nb) oxide catalyst during hydrogen absorption and desorption reactions was investigated by in-situ X-ray absorption spectroscopy (XAS). Results indicated that H2 was easily dissociated on the catalyst because the hydrogen absorption kinetics was significantly improved, and then the hydrog…
Carbon nanotubes possess many interesting properties, which make them a promising material for a variety of applications. In this paper, we present a unified framework for the simulation of the mechanical behavior of carbon nanotubes. It allows the creation, simulation and visualization of these structures, extending…
The hydrogenated amorphous silicon (a-Si:H) based p–i–n diode structures Al/a-Si:H(p+)/a-Si:H(i)/(silicides NPs/a-Si)x/a-Si:H(i)/a-Si:H(n+)/ITO/glass with multiple layers (x = 8,…,15) of the embedded narrow band semiconducting nanoparticle silicide (CrSi2, Mg2Si, and Ca2Si) multistructures have been grown by combining…
Thermoelectric generator devices have been prepared from 200 alternating layers of SiO2/SiO2+Ge superlattice films using DC/RF magnetron sputtering. The 5 MeV Si ionsbombardmenthasbeen performed using the AAMU Pelletron ion beam accelerator to formquantum dots and / or quantum clusters in the multi-layer superlattice…
The article focuses on the use of synchrotron X-rays and the recreated operational environment of a jet engine in analyzing material responses. Topics covered include the service conditions for materials such as high temperature and heat flux, the characterization of thermal barrier coatings (TBCs) and the challenges…
Our aim is to prove the existence and uniqueness of solutions for one-dimensional Cahn-Hilliard and Allen-Cahn type equations based on a modification of the Ginzburg-Landau free energy proposed in [8]. In particular, the free energy contains an additional term called Willmore regularization and takes into account stro…
The external Hele--Shaw problem when an air bubble is surrounded by oil is considered. It is assumed that the bubble expands with negligible surface tension. Howison [P. Roy. Soc. Edinburgh Sect. A, 102 (1986), pp. 141--148] proved that the elliptical initial shape of the bubble is the only shape that grows for all ti…
The purpose of this paper is to examine the effects of osmotic drying on the mass transfer and shrinkage of quinces. The osmotic drying was performed in a sucrose and water solution. The temperatures of osmotic solution were 40 oC and 60 oC, and the initial concentrations were 50 oBx and 65 oBx. All four combinations…
