Modification of Non-Metallic Inclusions in Oil-Pipeline Steels by Ca-Treatment

Metals, 2019
Corrosion rate in different steel grades (including oilfield pipeline steels) is determined by the presence of non-metallic inclusions (NMI) in steels.

CHARACTERISATION OF NON-METALLIC INCLUSIONS IN Pb-Ca-Sn ALLOYS

Materiali in Tehnologije
Non-metallic inclusions in two Pb-Ca-Sn lead alloys used in the manufacture of lead-acid batteries were investigated and categorised. Samples of recycled lead alloys were analysed using scanning electron microscopy (SEM) in combination with energy ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Study on Control Technology of Non-metallic Inclusions in 25MnBM Steel for Track Plate

Teshugang, 2020
The 25MnBM track plate steel is produced by 50 ton EAF short process. The control technology of TiN inclusions and the effect of RE on non-metallic inclusions in 25MnBM of steel are studied.
