The Effect of Liquid Nitriding and Carborizing on Adhesive Wear Resistance of Carbon Steel 1020 [PDF]
The aim of this paper is to study the effect of Nitro carburizing on adhesive wear resistance of carbon steel (1020 AISI). Four groups of specimens were manufactured (A, B, C, D) with dimensions (D20*10 mm) according to ASTM standard .

This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

The special carburizing by vacuum carburizing furnace
The carburizing process has been used as surface hardening technology for many years. Carburizing process has been widely used mainly in the machine industry, and has resulted by the end of today.Recently, the vacuum carburizing process has attracted attention not only as the conventional gas carburizing process but as a new carburizing method.The ...

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.
