- Discussions on rheology and structure in surfactant aggregates, AV.EXT
- Vitrimers based on acrylic and vinylic polymers crosslinked via dynamic ester and amide bonds: development, processing, formulation and recycling, AP.R
Abstract
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…
- Multiuser equipment approved in grant 21/12076-1: Quartz Crystal Microbalance with Dissipation (QCM-D), AP.EMU
Abstract
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…

Abstract
This proposal aims at the complementary investigation of thermodynamics and ultrafast dynamics of polymer solvation (AU)
- Applying scattering techniques to the study of colloidal systems, AV.BR
Abstract
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.

- Dispersion of cellulose nanocrystals in aqueous media, AP.R SPRINT
Abstract
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…

- Compact polyelectrolyte complexes from polysaccharidic precursors, BP.DD
Abstract
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…
- Complex coacervate core micelles and polyelectrolyte complexes for gene therapies: unrevealing thermodynamics and structural features, optimizing biological responses, BP.PD
Abstract
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…

- Spheres vs. Rods: study of the rheological properties of polyelectrolyte complexes with gold nanoparticles, BP.IC
Abstract
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)
- Expanding the domain of complex coacervate core micelles: formation of mixed micelles and in non-aqueous solvents, BP.DR
Abstract
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…

Abstract
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…
- Designing Rules for protein encapsulation into complex coacervate core micelles (C3M), BE.EP.DD
Abstract
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…

Abstract
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…
