Underwater Luminescence

The synthesis of this purely organic compound involves many techniques of organic chemistry. It is the culmination of 5 successful syntheses. The project arises for implementation in biosensing devices due to the excellent luminescence obtained when dissolved in water.

Moment of Creation

This photo was captured when a metal, heated up past the melting point, is ejected to a cold, fast moving, copper wheel. The result is the creation of an amorphous metallic ribbon.

A mushroom in my sample? :O

Sample of a galactomannan cryogel. This image is the consequence of the inherent process of preparing this type of sample, in which we do not want to destroy the porous structure, which by coincidence gave rise to this unusual result.

Inclusive Workplaces Benefit Everyone

Taking concrete steps towards greater LGBTQ+ inclusivity is a key part of fostering diverse and welcoming scientific workplaces. Last year in the Exploring the Workplace for LGBTQ+ Physical Scientists report, Royal Society of Chemistry (RSC) found that although the workplace climate is generally improving, more actions are needed to build genuine LGBTQ+ inclusivity in the physical sciences. Based on data analysis and further research, RSC has decided to create a set of resources that tackle the key issues faced by LGBTQ+ physical scientists. More details at At Bioinorganic Chemistry Lab (DQUA/CICECO) we are profoundly engaged in the promotion of an inclusive workplace.

United Colours of Phenolic-Based Coordination Compounds

Phenolic compounds are a prevalent group of natural molecules that are considered an indispensable component in a variety of nutraceutical, pharmaceutical, and medicinal applications, due to their anti-oxidative, anti-inflammatory, anti-mutagenic, anti-diabetic, antibacterial, and anti-carcinogenic properties. However, despite their multiple health-related properties, phenolic compounds present some characteristics (such as low solubility, low bioavailability, instability, and degradability) that strongly interfere with their biological activity and thus are obstacles to their clinical use. Approaches directed to overcome these drawbacks are of major interest. In this context, phenolic-based coordination compounds (or phenolic-based metal complexes) emerge as a viable alternative. At Bioinorganic Chemistry Lab (DQUA/CICECO) we currently synthesize phenolic-based metal complexes for medicinal applications, such as bacterial resistance, cancer, cardiac disease, and diabetes.

Metal Complexes: A Powerful and Coloured Tool

In the last decades, a plethora of metal complexes (coordination compounds) have been investigated as anticancer, antidiabetic, antimicrobials, and antiviral agents as well for many other medicinal applications. However, despite the encouraging results, very few complexes have been successfully translated into the clinical. In comparison with organic drugs, metal-based compounds are less investigated in preclinical screenings and, consequently, in clinical trials, suggesting that their potential remains untapped. Coordination compounds present unique properties and provide invaluable opportunities for the discovery of therapeutic agents with a novel mechanism of action, able to address the ever-complex health challenges that the world is currently facing. Some of the metal complexes (and their beautiful colours) synthesize at Bioinorganic Chemistry Lab (DQUA/CICECO). Ariana Santos & Diogo Marinheiro

From Cocoons to Green Energy

The development of new, more eco-friendly materials is essential to reduce greenhouse gas emissions and comply with the 2030 Agenda for Sustainable Development to combat climate change. Therefore, bio-based and biodegradable polymers are major players to design innovative cost-effective and eco-friendly materials with customizable properties and performance.

Photograph by Hugo Ribeiro @hugoribeirofotos BioMEMs is a high-potential, high-risk project that aims to develop advanced devices based on bio-compatible electromechanical systems for rapid implant regeneration through layer-based hard tissue engineering/iron coatings BioMEMs explores the fabrication of a BioElectroMechanical device designed for the in-situ promotion of bone growth by coating (bio)metal substrates with layers of biodegradable and or biocompatible oxides or polymers with ferroic properties (piezoelectric, flexoelectric, ferroelectric), layers that may or may not be functionalized. The project leader is Professor Paula Vilarinho from Electroceramics Group. Maxim Ivanov, Júlio Rocha and Noelle Zanini are also active members of the project.

Aveiro - a challenge for passivation process

Aveiro is a challenge for materials resistance. The passivation, a chemical treatment of steel and other alloys to enhance the ability of the treated surfaces to resist corrosion, is usually compromised by the wet marine climate of Aveiro.

Resolução de problemas: como ter uma perspectiva diferente" / "Problem solving: how to get a new perspective

Looking down at our world, we can see with greater clarity that problems, sometimes, are not that hard to solve and all we need is to look at them differently with a fresh look, as we did in the beginning. Sounds easy right? Why not live our lives at a slower pace?

Through the looking glass

Reflections are part of our daily life. For ages, humans have been always fascinated by mirrors and their mysterious powers of reflection. Water was the first reflective surface that humans have been aware of, and it has been reflecting the challenges of past and their impact in our present and future. Since people connect better with images, we also wanted to capture those reflections, showing how life was before the present time. Looking back, there is one constant target of reflection that greatly impacted our lives – materials. Their invention and evolution route dictates the path of human life. We often associate the concept of material technology with the avant-garde and the future, but most everyday objects are technological materials. They developed from what was once cutting-edge technology, as an accumulation of experiences, knowledge, and techniques to achieve our present needs. We are moving towards greener and more sustainable materials, and despite of that, they will continue to be reflected and their evolution captured.

Aveiro, Ria, and the University in more one day

This image shows what was and what is Aveiro through the beauty of a sunset in its estuary. We can also see the University, which has become an integral part of this city. Even at nightfall, it still has lights on and open doors in a continuous formation of new knowledge and, more importantly, people.

Hidden beauties on University of Aveiro campus

This picture is from the natural lake of the University of Aveiro, Santiago campus. Altough it is in the middle of the campus, the natural vegetations aroud the lake turns it in a hidden beautie. In fact, i used to park side by side with it for months without noticing it existence. I took this picture with a friend of mine, Mariana Silva, while we are returning from lunch.

Nature and time, always

The recapture of these ruins by nature shows us the beauty in change and the strength of time. Sidenote is great walking around the campus after lunch to take photos with friends. Shoutout to Manuel for the camera expertise.
