White to off-white solution 2.8 AutoIgnition 365° F; 300° F; 347° F (USCG, 1999) 2.9 Storage Acetaldehydeshould be used only in areas free of ignition sources, and quantities greater than 1liter should be stored in tightly sealed metal containers in areas separate fromoxidizers. Acetaldeh...
CelluloseCovalent adaptable networksDespite covalent adaptable networks (CANs) imparting the favorable features of crosslinked polymers, as well as the functionality of reprocessing, reshaping and welding, due to exchange reaction enabled topology changes; it is still a huge challenge to design catalyst-...
4381Accesses 2Altmetric Metrics Abstract Carcinogens often generate mutable DNA lesions that contribute to cancer and aging. However, the chemical structure of tumorigenic DNA lesions formed by acetaldehyde remains unknown, although it has long been considered an environmental mutagen in alcohol, tobacco,...
(b) Schematic illustration of non-aromatic disulfide bond exchange reaction and (c) the effect of polymer structure changes on the dynamic property of the polymer network. This figure is reproduced from Ref. [121] with permission from Wiley. Based on aromatic sulfide as the dynamic moiety, ...

Barrier function was the same in all exposure groups before and after treatment, suggesting that a monolayer leak was not a contributing factor to changes in sIgA transcytosis. Vectoral transport integrity was maintained because no sIgA was detected in the basal compartment of ALI and no loss of...
A–E: Determination of glucose and endogenous reactive metabolites in 96 hpf old zebrafish larvae displayed significantly increased AA (C) in aldh2.1−/− mutants, but no changes for glucose (A), MG (B), 4-HNE (D) or ACR (E), n = 3–15 clutches, 50 larvae per clutch. ...
Considerable changes in the properties of the product result in both cases. Therefore, attempts have already been made to plasticize polyvinyl acetals internally. According to U.S. Pat. Nos. 2,356,479 and 2,459,488, this can be achieved in principle by acetalation with alkoxyacetaldehydes...
