Surface Area of Kevlar® Polymer Particles: A New NMR Method
Poster Summary
Surface characteristics influence the properties of mixtures of solid particles in a liquid medium, e.g. saturated clay, gels, and colloidal suspensions. Conventional techniques used in the characterization of surface area and porosity of solids usually require aggressive and tedious preparation steps. In this research poster, we discuss the use of Low-Field Nuclear Magnetic Resonance (LF-NMR) for the assessment of Kevlar® particles in aqueous suspensions. The LF-NMR data displayed good agreement with alternative techniques, confirming its feasibility as a convenient method for studies at in-situ conditions.

Continuous Manufacturing: A New Perspective for the Pharmaceutical Industry
Poster Summary
The implementation of continuous processes in the pharmaceutical industry may lead to several technical improvements and cost reduction. In this research poster, the benefits of the migration from batch processes to operations executed in continuous flow reactors are discussed as well as multiple strategies for more effective and sustainable methods for the manufacturing of drugs and fine chemicals.

A Closer Look at the Most Important Reaction in Biomass: Hydrodeoxygenation
Poster Summary
1,6-Hexanediol, chemical formula C6H14O2, is a widely used precursor for polyesters, polyurethanes, and potentially Nylon 6-6. Nowadays, hexanediol has mostly been produced from adipic acid, which is derive from crude oil. In addition to the the use of non-renewable resources, the process itself involves hazardous chemicals and requires high amounts of energy. In this research poster, alternative routes for the obtainment of precursors from biomass are proposed and discussed. Insights obtained from mechanistic studies may support the development of more effective and environemnt-saving processes.

NMR Relaxation as a Method of Exploring Soft Porous Networks
Poster Summary
Hydrogels are 3D-structured hydrophilic polymers with important applications in the biomedical field, such as drug delivery and tissue engineering. Understanding their structural features at microscopic levels is fundamental to determine the most adequate uses and develop new products. Conventional techniques used in the characterization of porous media like hydrogels, generally require aggressive drying steps, which may lead to structural collapse. Thus, in this research poster, the application of Low-Field Nuclear Magnetic Resonance (LF-NMR) is discussed as a method for the studies of the pore structure of different hydrogels. The results display good agreement between the LF-NMR response and the expected trend as the polymer is changed and its concentration is increased.

Control of Mechanical Stability of Hollow SIlica Particles, and Its Measurement by Mercury Intrusion Porosimetry
Poster Summary
Hollow particle technology holds promise for a variety of applications. Determining their stability is an important task and therefore, should be included in the material design. In this research poster, the stability of hollow silica particles (HSP) was characterized with mercury intrusion porosimetry (MIP) and gas adsorption. MIP displays high potential for the obtainment of stability information from uniform hollow sphere particles, where other characterization techniques, e.g. Atomic Force Microscopy, can be used as supporting data.
