O objetivo deste artigo é apresentar algumas considerações da interface Arqueologia Histórica na cidade de Manaus, socializando também as pesquisas desenvolvidas pelo Núcleo Interdisciplinar Pesquisas Arqueológicas Bacia Amazônica – NIPAAM, referentes a este campo. A contempla o estudo cultura material do passado mais recente compreendendo diversidade fontes disponíveis, em meio aos processos t...

New series of thermo-pH multi-responsive terpolymers were fabricated. Cationic acrylate monomer was synthesized and named by [2-((ditert-butylamino)methyl)-4-formyl-6-methoxyphenyl acrylate] abbreviated as (DTBAVA). 1H NMR 13C investigated the new compounds FT IR. The fabricated free radical polymerization N-isopropylacrylamide NIPAAm, 10 mol% N, N-dimethylacrylamide 5, 10, 20 DTBAVA. investiga...

A new method for the qualitative analysis of adenosine nucleotides (AMP, ADP, and ATP) and synthetic oligonucleotides has been proposed, utilizing a pH- and temperature-responsive polymer of N-isopropylacrylamide (NIPAAm), butyl methacrylate (BMA) and N,N-dimethylaminopropylacrylamide (DMAPAAm) as the stationary phase of HPLC. In the chromatographic system using the copolymer with ionizable gro...

This review introduces the self-oscillating behavior of two types of nonthermoresponsive polymer systems with Ru catalyst moieties for the BelousovZhabotinsky (BZ) reaction: one with a poly-vinylpyrrolidone (PVP) main chain, and the other with a poly(2-propenamide) (polyacrylamide) (PAM) main chain. The amplitude of the VP-based self-oscillating polymer chain and the activation energy for self-...
