TL;DR: In this article, the decomposition behavior of five selected amino acids in high-temperature and high-pressure water was studied using a continuous-flow tubular reactor, and the effect of temperature on reaction products, pathway, and rate was determined as a function of reaction time.

TL;DR: Production of low-molecular-weight carboxylic acids from the hydrothermal treatment of representative organic wastes and compounds with or without oxidant demonstrated that the presence of oxidants favored formation of organic acids with acetic acid being the major product.

TL;DR: In this article, the effects of molecular weight, D-lactide unit content (tacticity and optical purity), and crystallinity of poly(lactic acid) (PLA) films on the water vapor permeability was investigated.

TL;DR: This study reveals that hydrolysis of PLLA in the melt is an effective and simple method to obtain l-lactic acid and to prepare P LLA having different molecular weights without containing the specific low-molecular-weight chains, because of the removal of the effect caused by crystalline residues.

TL;DR: The possibility of amino acids and glucosamine production from the treatment of shrimp shells in high-temperature and high-pressure water was investigated in this paper, where the highest amount of amino acid (70 mg/g of dry shrimp shell) from hydrolysis of proteins was obtained at a reaction temperature of 523 K in 60 min.
