• Abstract

  Because they play important physiological roles, biological cilia represent growing biomimetic inspiration for the production of artificial cilia, which may present responsiveness to external stimuli - e.g., magnetic field - if properly additivated. In this context, this research addresses composites of elastomeric matrix filled with magnetic particles, which allow the fabrication of elon…

  Magnetic Drawing for the Optimized Production of Artifical Polymeric Cilia, BP.IC

• Abstract

  The current state-of-the-art in materials science allows for a deep understanding of the microscopic level of matter, in addition to its manipulation with high modeling capacity. However, a technological bottleneck lies in bulk materials, such as particulates, whose macro compositions are associations between smaller building blocks. One of the sustainable and efficient ways to engineer b…

  Swimming supraparticles: controlling the motility of nanocellulose/yeast supraparticles through surface chemistry, BP.IC

• Abstract

  In line with the increasing demand for sustainable multifunctional materials, this study is intended to produce highly porous materials featuring extremely low densities - so called aerogels - using cellulose nanofibers extracted from renewable sources, such as the agricultural waste generated in sugarcane processing (bagasse). In an effort to provide the nanocellulose aerogels with antim…

  Surface modifications and polyelectrolyte adsorption via layer-by-layer onto cellulose nanofibers for the production of antimicrobial aerogels, BP.PD

(Only some records are available in English at this moment)

• Abstract

  This research is devoted to the development of living materials using biorenewable colloids. Basically, cellulose nanofibrils (CNF) are combined with Saccharomyces cerevisiae cells and dried in a controlled fashion into supraparticles that combine the binding capacity of the interlocked CNF matrix and the enclosed yeast cells that retain their metabolic function. The microbial metabolism,…

  Engineering the interfacial behavior of self-propelled yeast/nanocellulose supraparticles by tailoring the surface chemistry of cellulose nanofibrils, BE.EP.IC

• 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…
