Pure Hydrolysis of Polyamides: A Comparative Study [PDF]

open access: yesChemistry, 2023
Polyamides (PAs) undergo local environmental degradation, leading to a decline in their mechanical properties over time. PAs can experience various forms of degradation, such as thermal degradation, oxidation, hydrothermal oxidation, UV oxidation, and ...

The hydrolysis of hydroxamic acid complexants in the presence of non-oxidizing metal ions 2: Neptunium (IV) ions. [PDF]

open access: yes, 2008
Hydroxamic acids are salt free, organic compounds with affinities for cations such as Fe3+, Np4+ and Pu4+, and have been identified as suitable reagents for the control of Pu and Np in advanced nuclear fuel reprocessing. The results of a UV-visible, near-

Rennet-Induced Casein Micelle Aggregation Models: A Review

open access: yesFoods, 2022
Two phases are generally recognized in the enzymatic coagulation of milk: hydrolysis and aggregation, although nowadays more and more researchers consider the non-enzymatic phase to actually be a stage of gel formation made up of two sub-stages: micellar
