Structure and dynamics of nano-sized raft-like domains on the plasma membrane
(American Institute of Physics, 2012-01)
Cell membranes are constitutively composed of thousands of different lipidic species, whose specific organization leads to functional heterogeneities. In particular, sphingolipids, cholesterol and some proteins associate ...
Sizes of lipid domains: What do we know from artificial lipid membranes? What are the possible shared features with membrane rafts in cells?
(Elsevier Science, 2017-05)
In model lipid membranes with phase coexistence, domain sizes distribute in a very wide range, from the nanometer (reported in vesicles and supported films) to the micrometer (observed in many model membranes). Domain ...
Flux and provenance of ice-rafted debris in the earliest Pleistocene sub-polar North Atlantic Ocean comparable to the last glacial maximum
(Amsterdam, 2012-07-13)
Relatively little is known in detail about the locations of the early Pleistocene ice-sheets responsible for ice-rafted debris(IRD) inputs to the sub-polar North Atlantic Ocean during intensification of northern hemisphere ...
Thermal Characterization of “Comb-Like” Block Copolymers Based on PCL Obtained by Combining ROP and RAFT Polymerizations
(Wiley, 2016-10-21)
In this work we report the synthesis of poly(hydroxyethylmethacrylate-graft-polycaprolactone)-block-poly(caprolactone) copolymers,P(HEMA-g-PCL)-b-PCL, by combining ring-opening polymerization (ROP)and reversible ...
Polímeros fluorados anfifílicos para aplicação em diagnósticos por imagens de ressonância magnética
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2014-12-17)
The goal of this study is to present kinetic studies of (co)polymerization as well
as the synthesis and characterization of amphiphilic copolymers with a fluorinated
segment. Copolymers were obtained by RAFT (co)polymerizations ...
