Perovskite Solar Cells:the new age of photovoltaics?

Cristina Teixeira

PhD Student at LEPABE/PPE

Cristina Teixeira received his BSc and MSc degrees in Chemical Engineering from FEUP. Currently, she is a 2nd year PhD student in Chemical Engineering at LEPABE under the supervision of Prof. Luísa Andrade and Prof. Adélio Mendes, focusing on the industrialization challenges of perovskite solar cells, namely stability enhancement and fabrication cost reduction. She has published 2 articles and won 1st price for oral presentation in a European Student Research Conference.

Talk summary

The production of energy through fossil fuels is responsible for the release of green-house and other toxic gases to the atmosphere, which is harmful to the environment and for human health. It is of utmost importance to develop cleaner and safer ways of producing energy. Perovskite Solar cells are a very young photovoltaic technology that has already demonstrated a big potential. In this presentation, an overview of this technology will be made, along with a presentation of the current status of the research work in our group.

Shipping emissions modelling - revealing a

black secret of the sea

Rafael Nunes

PhD Student at LEPABE/PSE-ENV

Rafael Nunes is a PhD student currently enrolled in Environmental Engineering doctoral program, at LEPABE FEUP. He has a MSc in Environmental Engineering, concluded in 2014. His main research activities are related to air quality monitoring and modelling, exposure to air pollution, and its health impacts as well as related economic burden. He has been doing research at LEPABE in the Process Systems Engineering and Environmental Sciences and Technologies groups since 2014.

Talk summary

This talk will focus on shipping emissions and their impacts on human health in the Iberian Peninsula. Major results from the air quality and health impacts as well as, their economic valuation will be presented for the Iberian Peninsula for 2015. A special focus will be given to the relevance of the study of shipping emissions and the use of the modelling processes to understand the impacts of the emissions from this sector.

Microencapsulation: chemical engineering applied to the microscale

Berta Estevinho

Junior Researcher at LEPABE/SA

Berta Estevinho graduated in Chemical Engineering (2003), with a Master in Environmental Engineering (2005) and a PhD in Chemical and Biological Engineering (2010), all from FEUP.

Since 2004, she is working in LEPABE (LEPAE). In 2016, she was visiting researcher at IATA - CSIC, Valencia (3 months).

B. Estevinho is researcher in the field of microencapsulation of active and natural compounds, working with spray-drying and electrospinning techniques. .

Talk summary

This presentation will cover the application of chemical engineering concepts to the microscale. In the microencapsulation processes several chemical phenomena are involved. Two of the most relevant microencapsulation processes will be presented: Spray drying and electrospinning.

Microencapsulation is a promising alternative to improve the stability, controlled release and bioavailability of bioactive ingredients, enabling their incorporation in food products, nutraceuticals, cosmetics, therapeutic formulations and medicines, among others.
