Desulfurization of FCC Gasoline: Novel Catalytic Processes with Zeolites
(Berkeley Electronic Press, 2008-01)
New regulations aim to achieve a drastic sulfur emission reduction in fuels and impose very low sulfur concentration caps (30 ppm in gasoline and 15 ppm in diesel) that will be in full force in 2009. FCC gasoline represents ...
Conformational transition of Aβ42 inhibited by a mimetic peptide. A molecular modeling study using QM/MM calculations and QTAIM analysis
(Elsevier, 2016-03)
The main pathogenic event in Alzheimer's disease is believed to be the aggregation of the amyloid β-peptides into toxic aggregates. In a previous work we designed a mimetic peptide possessing a significant aggregation ...
Selective synthesis of acetaldehyde from lactic acid on acid zeolites
(Elsevier Science, 2018-03)
The gas-phase lactic acid conversion to acetaldehyde was studied on zeolites HMCM22, HZSM5 and NaZSM5 in a plug-flow fixed-bed reactor at 583. K. HMCM22 was a strong Brønsted acid zeolite that yielded 39.7% of lactic acid ...
Oligoésteres e poliésteres obtidos a partir do ácido oleico modificado com forma estrela: síntese e caracterização físico-química
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2012-07-30)
This works investigated the curing reaction of epoxidized oleic acid starshaped
with different anhydrides, forming product as oligoésteres and polyesters.
Oleic acid modified was obtained by esterification of oleic acid ...
Bioadsorção dos inibidores gerados no pré-tratamento da biomassa lignocelulósica em biorrefinarias
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2020-04-29)
In the pretreatment stage of lignocellulosic biomass in biorefineries can release compounds that act as inhibitors of the enzymatic hydrolysis and alcoholic fermentation steps. Among the inhibitors, the phenolic compounds ...
Preparo de hidrogéis a base de gelatina/tanfloc e estudo de liberação controlada
(Universidade Tecnológica Federal do ParanáApucaranaBrasilLicenciatura em QuímicaUTFPR, 2017-11-20)
Hydrogels are materials that exhibit great capacity to absorb water, being formed by three-dimensional polymer networks. Hydrogels may be used as a drug carrier matrix in controlled drug release, can promote soil conditioning ...
The Polyphenol Altenusin Inhibits in Vitro Fibrillization of Tau and Reduces Induced Tau Pathology in Primary Neurons
(American Chemical Society, 2017)
In Alzheimer’s disease, the microtubule-associated
protein tau forms intracellular neurofibrillary tangles (NFTs). A
critical step in the formation of NFTs is the conversion of soluble tau
into insoluble filaments. ...
Critical role of the first transmembrane domain of Cx26 in regulating oligomerization and function
(2012)
To identify motifs involved in oligomerization of the gap junction protein Cx26, we studied individual transmembrane (TM) domains and the full-length protein. Using the TOXCAT assay for interactions of isolated TM α-helices, ...
Ryanodine receptor-mediated Ca2+ release underlies iron-induced mitocondrial fission and stimulates mitocondrial Ca2+ uptake inprimary hippocampal neurons
(2014)
Mounting evidence indicates that iron accumulation impairs brain function. We have reported previously that addition of sub-lethal concentrations of iron to primary hippocampal neurons produces Ca2+ signals and promotes ...
Pretratamiento con agua líquida caliente de raquis de banano
(2012-11-24)
Los residuos generados después de la producción de banano representan un material celulósico abundante que tiene potencial para ser usado en la producción de biocombustibles celulósicos. La conversión eficiente de biomasa ...
