How to take advantage of wine tourism: Creation of a new concept for central Alentejo based on its potential and worldwide success factors

Wine Tourism is gaining importance in today’s world and more destinations and establishments have been arising. After understanding the importance of this economic activity and the factors it must have to succeed, a new project was conceived for Central Alentejo taking into account its potential. This project is an example of how to take advantage of Wine Tourism in wine regions that are underexplored, such as Aldeias de Montoito, the village near Redondo to which a Business Plan will be created, explaining the strategies to pursue in order to have a successful Wine Tourism destination.

Can a lemon based Sagres product attract consumers that don't drink beer?

The purpose of this project is to understand if the brand Sagres is damaging the product Sagres Radler. The beer market in Portugal was studied and focus groups were used to perceive the impact of the brand in the product. The mother brand is bringing the beer association into a product designed to engage people that don’t like beer. With the insights, a new proposal was drawn and tested. Although it was not possible to prove that the new concept is better for the population, there are strong indications that the brand isn’t enabling the achievement of the proposed target.

A consumer research project as the basis for the development of a marketing plan for a new spirit brand producing gin in Germany

This work project is about developing a marketing plan for a new gin brand in Germany. It is based on consumer and market research, including Portugal as a trend market for the qualitative research. For the undertaking it is seen as fundamental to understand the industry as well as the consumer needs, attitudes and preferences. Furthermore, it is important to consider the estimation of opinion leaders and trendsetters in the industry. In this context it turned out that barkeepers have a key-influencing role for the stimulation of demand. Based on the insights from this research as well as on the gained market knowledge, the marketing plan was developed. The goal is to convince other brand users to switch brands.

Engineered MRI nanoprobes based on superparamagnetic iron oxide nanoparticles

This project aimed to engineer new T2 MRI contrast agents for cell labeling based on formulations containing monodisperse iron oxide magnetic nanoparticles (MNP) coated with natural and synthetic polymers. Monodisperse MNP capped with hydrophobic ligands were synthesized by a thermal decomposition method, and further stabilized in aqueous media with citric acid or meso-2,3-dimercaptosuccinic acid (DMSA) through a ligand exchange reaction. Hydrophilic MNP-DMSA, with optimal hydrodynamic size distribution, colloidal stability and magnetic properties, were used for further functionalization with different coating materials. A covalent coupling strategy was devised to bind the biopolymer gum Arabic (GA) onto MNPDMSA and produce an efficient contrast agent, which enhanced cellular uptake in human colorectal carcinoma cells (HCT116 cell line) compared to uncoated MNP-DMSA. A similar protocol was employed to coat MNP-DMSA with a novel biopolymer produced by a biotechnological process, the exopolysaccharide (EPS) Fucopol. Similar to MNP-DMSA-GA, MNP-DMSA-EPS improved cellular uptake in HCT116 cells compared to MNP-DMSA. However, MNP-DMSA-EPS were particularly efficient towards the neural stem/progenitor cell line ReNcell VM, for which a better iron dose-dependent MRI contrast enhancement was obtained at low iron concentrations and short incubation times. A combination of synthetic and biological coating materials was also explored in this project, to design a dynamic tumortargeting nanoprobe activated by the acidic pH of tumors. The pH-dependent affinity pair neutravidin/iminobiotin, was combined in a multilayer architecture with the synthetic polymers poy-L-lysine and poly(ethylene glycol) and yielded an efficient MRI nanoprobe with ability to distinguish cells cultured in acidic pH conditions form cells cultured in physiological pH conditions.
