LNG storage tank evaporation influence factor analysis [PDF]

International Journal of Fluid Engineering
The static evaporation of liquefied natural gas (LNG) is a key factor influencing the safety of LNG storage tanks, since it leads to boil-off gas (BOG) generation and pressure rise inside the tank.

Research on Mechanism of Methanol–Hydrogen Co-Transport Inhibiting Hydrogen Embrittlement in Pipeline Steel

Metals
Existing studies suggest that hydrogen embrittlement will occur in pipeline steel under a hydrogen environment, and gas is often used as a hydrogen embrittlement inhibitor. As one of the most effective hydrogen carriers, methanol may competitively adsorb

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Effect of Heat Treatment Temperature on the Microstructure and Mechanical Properties of Fe-18Mn-0.6C-xAl

Metals
High-Mn steels are commonly fabricated by hot rolling and on-line cooling for cryogenic applications, because there exists an aging embrittlement zone in most high-Mn steels, and this shortcoming makes it difficult to optimize their mechanical properties
