AFM analysis of duplex steel structure and composition
Open Research DataDue to the high content of alloying elements, duplex stainless steels are characterized by a complex structure of phase transitions. Among all types of intermetallic compounds, the sigma phase is of major interest due to its detrimental effect on both mechanical properties and corrosion behavior. It is an intermetallic phase enriched in Cr and Mo and...

The structure of vanadate glass-ceramics containing BaTiO3.
Open Research DataThe structure of vanadate glass-ceramics doped with BaTiO3 was measured by SEM technique. Samples of the composition of x[BaO,TiO2]–(80 − x)V2O5–20Bi2O3 where x = 5, 10 and 15 in mol% were prepared by a conventional melt quenching technique. The melting was performed in alumina crucibles at the temperature of 1273 K–1373 K. The melts were poured on...

Structural investigations of the Al2O3 ultra thin films
Open Research DataUltra-thin layers of Al2O3 were deposited by atomic layer deposition (ALD) (Beneq TFS 200 ALD system). This method provides precise thickness control down to a single atomic layer. The precursors used were trimethylaluminum (Sigma-Aldrich) and purified water. The deposition of the atomic layer was carried out at 200 °C. Samples with a thickness of 2...

Synthesis and reactivity of 2,2,4,4-Tetrakis(tri-tertbutoxysilane-thiolato)-1,3,2,4-dithiadistannetane - crystal and molecular structures of two polymorphic forms
PublicationTytułowy związek [Sn(μ-S){SSi(OtBu)3}2]2 (1), zawierający dwa, 4-koordynacyjne atomy cyny, krystalizuje w dwóch odmianach polimorficznych. Forma ortorombowa-1a, została otrzymana w reakcji (tBuO)3SiSH i Et3N z SnCl2, podczas gdy forma trójskośna-1b, w reakcji z SnCl4 jako substratem. Struktura krystaliczna i cząsteczkowa obydwu odmian polimorficznych została wyznaczona przez badania metodą Rentgenowskiej Analizy Strukturalnej,...

On the complex formation of iron(III) bromide in the space-demanding solvent N,N'-dimethylpropyleneurea and the structure of the trisbromoiron(III) complex i solution and crystalline state
PublicationPrzeprowadzono badania kalorymetryczne równowag kompleksów koordynacyjnych jonu żelaza(III) z jonami bromkowymi w DMPU. Stwierdzono, że w DMPU powstają trzy: mono-, di- i tribromkowe kompleksy żelaza(III) a ich powstawanie jest uwarunkowane zmianą entropii. Badania krystalograficzne dowiodły, że FeBr3 w roztworze DMPU ma konfigurację płaskiego trójkąta równobocznego, żadna cząsteczka rozpuszczalnika nie jest związana z jonem metalu,...

Economic growth, structural change and quality upgrading in New Member States
PublicationThe purpose of this research is to present the recent developments concerning structural change and productivity growth in New Member States and the role played in such process by country specific factors. We focus on ten countries (NMS-10) which joined the EU in 2004 and analyze productivity dynamics of their labor structures between the years 1995 and 2005 in a comparative setting versus EU-15 economies. NMS-10 have gone through...

Azomacrocyclic derivatives of imidazole: synthesis, structure, and metal ion complexation properties
PublicationNew azocrown ethers comprising imidazoles in the macrocycle have been synthesized. Imidazole, 2-methyl-, 4-methyl-, and 4-phenylimidazole were incorporated to form macrocyclic units by coupling with the appropriate bis-diazonium salts. The syntheseswere performed under high dilution conditions. The X-ray structure of a water adduct of the 21-membered crown ether derivative of 4-methylimidazole 8 has been solved. Metal...
