Organic pollutants photodegradation increment with use of TiO2 nanotubes decorated with transition metals after pulsed laser treatment
PublikacjaAmong various titanium(IV) oxide (TiO2, titania) structures, 1D nanotubes (TiO2 NTs) produced during the two-electrode anodization process, are extensively utilized in sensors or supercapacitors as well as in photo(electro)catalytic water splitting. However, due to wide bandgap and fast electron-hole recombination additional modifications, mostly concerned on materials surface, are required. According to the recent research, TiO2...

Mechanical properties and corrosion resistance of dissimilar stainless steel welds
PublikacjaW artykule przedstawiono właściwości mechaniczne oraz odporność korozyjną doczołowych złączy różnoimiennych stali odpornych na korozję, austenitycznej 316L oraz duplex 2205. Blachy o grubości 15 mm spawano automatycznie łukiem krytyn z różnymi energiami liniowymi. Wykazano, że właściwości mechaniczne złączy spełniają wymagania okrętowych towarzystw klasyfikacyjnych, natomiast najbardziej narażoną strefą złącza na działanie korozji...

Brittle fracture of 100-, 110-, 111-oriented Cu crystals: MD vs. TB/MD approach
PublikacjaPrzeprowadzono wieloskalowe symulacje nanoindentacji miedzi nieskończenie twardym narzędziem, przy zastosowaniu metody dynamiki molekularnej, z siłami liczonymi na bieżąco w formalizmie ciasnego wiązania (TB). Przedstawiono wyniki dla trzech orientacji krystalicznych podłoża. Badano efekt dołączenia obliczeń TB na siłę normalną odczuwaną przez narzędzie i na przemieszczenia atomów podłoża, przez porównywanie z symulacją czystą...

Corrosion of evaporator tubes in low emission steam boilers
PublikacjaPurpose of this paper is to reveal the mechanisms of corrosion processes of outer surfaces of low-emission steam boiler evaporator tubes. Examinations were performed to find the reasons of different corrosion susceptibility of tubes situated at combustion chamber on various levels. Examinations were conducted on several segments of 57 x 5.0 mm evaporator tubes made of 16M (16Mo3) steel grade. Segments were taken from level of...
