visit to discuss research results on rheological and structural characterization of surfactant aggregates (AU)
Vitrimers are polymeric materials that display properties similar to thermosets, such as dimensional, mechanical and thermal stability. However, the presence of dynamic covalent bonds imparts dynamic character to these properties that can be activated by temperature, light or microwaves. Their tridimensional polymeric network is prone to reprocessing, mechanical recycling and confers self…
This project aims at achieving controlled association of varied colloids through either hydrophobic, electrostatic, or covalent bonds (or their combination) to tailor their characteristics, preferably in a reversible fashion. The envisaged functional colloidal objects span from surfactant and/or polymer aggregates, to nanoparticles of inorganic nature (mostly silica) or derived from renew…

This proposal aims at the complementary investigation of thermodynamics and ultrafast dynamics of polymer solvation (AU)
This proposal aims at funding the visit of Prof Nadya P. da Silveira to IQ-Unicamp, for a period of around 5 months, to interact with projects being developed under the thematic project 2015-25406-5, fundamentally to bring her expertise in scattering techniques (both light and X-ray) for the investigation of different colloids. (AU)
In order to produce stable and processable cellulose nanocrystals (CNCs), fundamental understanding of the relationship between the surface chemistry, interaction forces and colloidal stability of CNCs is necessary. We will develop analytical tools for the quantification of interaction forces, macroscopic evaluation of the stability of CNCs, and chemical modification of CNCs. By careful a…

In this PhD project, compact polyelectrolyte complexes (CoPECs) with pH-controlled ion pairing behavior and ionic strength of the medium will be studied, using renewable and biodegradable polysaccharides as precursor materials. The project will focus on the use of cellulose, chitin, and their nanoparticulate (nanocrystals and nanofibers) and molecular derivatives, chemically modified to f…
The scope of this project is the design and synthesis of novel polymeric vectors (polycations and ionic-neutral block copolymers) towards the formulation of DNA- and RNA-based polyelectrolyte complexes and complex coacervates core micelles focusing on applications within the framework of gene carriers. Gene delivery using non-viral vectors is a multi-step process that currently poses many…

The role of the project is to investigate the effect caused on the rheology of polyelectrolyte complexes upon the inclusion of gold nanoparticles in different concentrations and aspect ratios, as physical crosslinkers between the polymeric chains of the coacervate.(AU)
Nanoparticles formed by electrostatic complexation between opposite charge species have been extensively investigated in recent years due to their different functionalities. Complex coacervate core micelle (C3Ms) is one class of these nanoparticles that has a core-shell structure formed by mixing aqueous solutions of a copolymer with a macromolecule of opposite charges. A diversity of mac…
Considering the need for the achievement of value-added compounds through optimized and environmentally correct processes, this project aims the development of interfacial catalytic systems for application in a variety of organic reactions. It will be obtained core-shell particles in aqueous medium from complex salts of dodecyltrimethylammonium and the block copolymer poly(acrylamide)-b-p…

Nanoparticles formed by electrostatic complexation between oppositely charged species have been extensively investigated in recent years due to their different functionalities. In this area are the complex coacervate core micelle (C3M), formed by the mixture of aqueous solutions of a copolymer with an oppositely charged macromolecule. The process of formation, characterization, and applic…
Inside cells, proteins and other biomolecules functions depend not only on their intrinsic characteristics, but also on the properties of the environment, like viscosity, water content and other related phenomena. However, it is curious that biomolecules remain stable and active inside the cell, but that outside this environment, they usually need special conditions to ensure their functi…
This research falls within the current scenario involving sustainable and multifunctional materials. Overall, it deals with the controlled deconstruction of the hierarchical architecture of chitin into nanochitin (NCh), which merges the inherent features of pristine chitin (renewability, biodegradability, biocompatibility, and biological activity, to mention a few) and the peculiarities o…
The proposed project aims the development of nanomaterials with specific and multiple functionalities. The idea is to prepare superparamagnetic iron oxide nanoparticles and functionalize their surfaces with different phosphonic acid-terminated polymers, combining the thermoresponsive PNIPAM (poly (N-isopropylacrylamide)) and PEO (poly(ethyleneoxide)) to modulate the nanoparticles interfac…
