Dual phase (DP) steels are rapidly becoming more and popular for automotive applications. They offer a weight reduction with combination of energy absorption crash zones. Rails, reinforcements, back panels, cross members, pillars can be given as application examples. DP microstructure consists soft ferrite matrix hard martensite islands. The islands provide strength while the ductile provides f...

AbstractIn this study, we explore the morphological and geochemical characteristics for 440 manganese nodules collected from two different water depths [ARA12B-St52 (150 m, n = 239) ARA12B-St58i (73 201)] on continental shelf of East Siberian Sea ARA12B expedition in 2021. We also discussed variations with varying Arctic Sea. The sizes are generally greater than 3 cm at both sites. However, the...

The processing of N-linked oligosaccharides in the secretory pathway requires the sequential action of a number of glycosidases and glycosyltransferases. We studied the spatial distribution of several type II membrane-bound enzymes from Glycine max, Arabidopsis thaliana, and Nicotiana tabacum. Glucosidase I (GCSI) localized to the endoplasmic reticulum (ER), alpha-1,2 mannosidase I (ManI) and N...

- The mechanism of diffusion layer growth in plasma nitrided coatings applied on a St52 steel using an active screen is investigated. The nitriding was performed at 450,500 and 550 ◦C temperature nitriding times of 5, 10 and 15 h, in a gas mixture containing 20 vol. % H2: 80 vol. % N2 and DC-pulsed plasma nitriding unit. The surface, cross section and the thickness of diffusion of specimens ...
