Soft amphiphilic polyesters obtained from pegs and silicon fatty compounds: structural characterizations and self-assembly studies
(2016)
Transesterification polymerizations between a silicon fatty ester derived from methyl 10-undecenoate and polyethylene glycol (PEG) monomers generate amphiphilic biopolyesters with maximum molecular weights within two hours ...
Redox-active polyamine-salt aggregates as multistimuli-responsive soft nanoparticles
(Royal Society of Chemistry, 2020-03-13)
Polyamine-salt aggregates have become promising soft materials in nanotechnology due to their easy preparation process and pH-responsiveness. Here, we report the use of hexacyanoferrate(II) and hexacyanoferrate(III) as ...
Assembleias de Ephemeroptera (Insecta) em riachos de cabeceirano bioma Cerrado
(Universidade Federal de Minas GeraisUFMG, 2014-01-31)
Different anthropogenic land uses have threaten biodiversity in rivers and streams, especially at tropical developing countries, due of their higher rates of changes of land uses. Sensitive organisms have been used for ...
Functional diversity revealed by removal experiments
(Elsevier Science London, 2003-03)
The dominant protocol to study the effects of plant diversity on ecosystem functioning has involved synthetically assembled communities, in which the experimental design determines species composition. By contrast, the ...
Caracoles terrestres del área protegida de Sierra de las Casas y sus problemas de conservación
(International Union for Conservation of Nature, 2015)
Las islas han inspirado a los biólogos desde el comienzo de la exploración científica, hace más de dos siglos. Desde la época de Darwin y Wallace, la investigación sobre biotas insulares ha contribuido sustancialmente a ...
Influência do uso e cobertura do solo sobre a ictiofauna de riachos das cabeceiras do Alto Rio Paranapanema
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Planejamento e Uso de Recursos Renováveis - PPGPUR-SoCâmpus Sorocaba, 2020-09-17)
Human activities have generated unprecedented impacts on aquatic biodiversity. Thus,
knowing the impacts generated by these activities is extremely important, as fish from the
Neotropical regions represents approximately ...
Integrating Taxonomic, Functional and Phylogenetic Beta Diversities: Interactive Effects with the Biome and Land Use across Taxa
(Public Library of Science, 2015-05)
The spatial distribution of species, functional traits and phylogenetic relationships at both the regional and local scales provide complementary approaches to study patterns of biodiversity and help to untangle the ...
Parameters of infiltration models affected by the infiltration measurement technique and land-use
(Sociedade Brasileira de Ciência do Solo, 2022)
Multitasking polyamine/ferrioxalate nano-sized assemblies: thermo-, photo-, and redox-responsive soft materials made easy
(Royal Society of Chemistry, 2019-11)
Responsive nanomaterials have emerged as key components in materials sciences. Herein, we report the one-step preparation of multi-stimuli responsive polyamine-salt aggregates (PSA) by ionically crosslinking polyethylenimine ...
