ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Systems With Cryogenic Liquefied Gases In Fire-Incidents
The volumetric energy density of a gas can be increased by liquefaction, which occurs when the gas is cooled below the saturation point. Liquefied gases of great importance to the energy transition are Liquefied Hydrogen (LH2) and Liquefied Natural Gas ...

The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Method for calculating the risks of transporting compressed gases and refrigerated liquefied gases
Sommige stoffen die in de chemische industrie worden gebruikt, zijn brandbaar of giftig. Wanneer deze stoffen van en naar de chemische industrie worden vervoerd, kan dat risico’s hebben voor de omgeving. Nederland heeft daarom beleid gemaakt om de risico’

The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Ambient air vaporizers (AVVs) are the most commonly used type of heat exchanger for cryogenic regasification stations. The transfer of heat from the environment for heating the liquefied gas and its vaporization is a cost-free and efficient method ...
