In this study, the non-isothermal kinetics of martensitic transition from 14M modulated martensite to austenite phase in Ni55Fe19Ga26 ribbons obtained by melt-spinning has been analyzed. The proximity room temperature makes it very sensitive pressure and subtle differences for different pieces ribbon (ascribed stresses stored during its rapid solidification process). Despite dispersion characte...

Heusler compounds and alloys based on them are of great recent interest because they exhibit a wide variety spin structures, magnetic properties, electron-transport phenomena. Their properties tunable by alloying we have investigated L21-orderd compound Ru2MnSn its varying the atomic Mn:Sn composition. While antiferromagnetic ordering with Néel temperature 361 K was observed in Ru2MnSn, Mn-poor...

Understanding phase stability and precipitation at intermediate temperatures is crucial for tailoring microstructures mechanical properties of L12-strengthened multicomponent alloys. In this study, the precipitate type, morphology, distribution (CoCrNi)100−2x(AlTi)x (x = 3, 5, 7 at.%) medium-entropy alloys (MEAs) 600-900 °C were systematically investigated through a combination scanning electro...

We performed incubation experiments with 15N-labeled nitrogen compounds to investigate the vertical distribution of pathways of N2 production through the suboxic zone of the central Black Sea and the impact of oxygen and sulfide on the anammox process. Anammox rates increased with depth through the upper suboxic zone and reached a maximum of ,11 nmol N2 L21 d21 at the sharp interface between ni...

Based on a study of knowledge transfer within more than 15 industries, across three forms of governance, and between both domestic and international R&D partners, knowledge transfer success was found to be associated with several key variables, and to hinge upon (a) both R&D units’ understanding where the desired knowledge resides within the source, (b) the extent to which the parties share sim...

In order to contribute to knowledge about structure of marine diazotrophic communities in the sediments of South China Sea, the molecular diversity of the nifH gene, which encodes the Fe protein of the nitrogenase complex, was assessed by polymerase chain reaction (PCR) amplification using PolF/R primers, followed by cloning and sequencing. Sequences of nifH genes were amplified from environmen...
