Study on Influencing Factors of Active Silicon Content Determination in Gibbsite
Kuangchan zonghe liyong, 2022 This paper mainly studies the factors affecting the determination of active silicon content in gibbsite. Active silicon is an important index of gibbsite. A method for the determination of active silicon in gibbsite was established by inductively coupled

Mesocrystal growth through oriented sliding and attachment of nanoplates [PDF]
Nature CommunicationsOriented attachment is a critical, yet poorly understood, crystal growth pathway based on the self-assembly of nanocrystals. During oriented attachment, solvent-separated particles align and coalesce through forces that enable precise rotation and ...

Changes in the Glucose Concentration Affect the Formation of Humic-like Substances in Polyphenol–Maillard Reactions Involving Gibbsite [PDF]
MoleculesThe polyphenol–Maillard reaction is considered one of the important pathways in the formation of humic-like substances (HLSs). Glucose serves as a microbial energy source that drives the humification process.
