This presentation will give a brief overview of the research being performed at IFIMUP in the "Advanced materials and processes for Energy" research area.
An overview of the activities made at C2TN in the thematic line of the Advanced Materials and Processes for Energy will be presented. Special emphasis will be given to the main activities made in this area at C2TN, in particular in the fields of thermoelectric materials and technology, as well as in intermetallics for hydrogen storage, biofuel production by organic materials irradiation and...
Energy considerations are essential in nowadays society and increasingly dependent on mobility and interconnectivity with the need to reduce the environmental impacts related to fossil fuels. The Centre of Physics at the University of Minho is undergoing competitive research in advanced materials for energy. Senen Lanceros is very active in the field of high energy density batteries,...
This keynote talk will briefly present the ongoing research in the Center of Physics and Engineering of Advanced Materials (CeFEMA) on the topic of Advanced Materials and Processes for Energy. The CeFEMA team members working in this topic come from the following groups: MemChem - Membranes, Chemical and Electrochemical Processes Group; LASYP - Laser-Assisted Synthesis and Processing Group;...
One of the greatest challenges of the 21st century is to reduce greenhouse gas emissions, while keeping the standard of living, by using more clean and renewable energy sources. Sunlight is by far the most abundant renewable source of energy, exceeding the potential of all other energy sources, and capable of supplying the present and projected world’s energy demands. Photoelectrochemical...
Nowadays, mobility, convenience, and safety of electronic devices are concerns present in our day-to-day life. Considering that everyday life small devices have a low-power consumption (mW or nW), the search for simple alternative energy sources is rapidly increasing. Energy Harvesting (EH) technology emerges as an excellent solution for this type of application, replacing batteries and...
Thermoelectric generators (TEG’s) are devices able of converting waste heat into usable electricity through the Seebeck effect, which makes them very attractive to fight against global warming. To develop novel TEG’s, made of more sustainable, cheap, and less toxic materials, many crucial aspects need to be considered. The nature and quality of the interface between the TE materials and the...
The anaerobic digestion of macroalgae is known for being a possible process to obtain biogas. However, due to the high organization of the macroalgae molecular structure, a pre-treatment is usually needed to improve the biogas production. In this context, gamma irradiation can be used as an alternative pre-treatment aiming to improve the digestibility of polysaccharides and other carbohydrates...
Zirconia and hafnia based thin films have attracted considerable attention in the last decade due to the existence of a ferroelectric behavior at the nanoscale, which can enable the downscaling of the next-generation of non-volatile memory and energy storage devices [1,2].
In this presentation an overview regarding the recent advances on these materials will be given [2]. Then, our most...
The modern world is facing a growing number of interconnected electronic devices in the scope of the Industry 4.0 and Internet of things concepts. As the technology develops and the devices get smaller, lighter and portable, the need for more efficient storage systems capable of powering these devices arises as a critical challenge. Despite their widespread use and strong position as leader in...
Alkaline water electrolysis offers a possibility of producing hydrogen gas without consuming fossil fuels. Namely, the use of electricity from renewable energy sources makes the electrolysis process green and hydrogen gas a green energy carrier, enabling switching from carbon-based to green and sustainable energy sources. However, most of the global hydrogen is currently still produce by the...
Three different Pt-M (M = Ni,Fe,Cu) based electrocatalysts were synthetised via simultaneous supercritical carbon dioxide (scCO2) deposition technique of nanoparticles on graphene nanoplatelets (GNPs). These were tested as electrocatalysts for oxygen reduction (ORR) and oxygen evolution (OER) reaction in metal-air batteries and unitized regenerative fuel cells (URFCs). Primary metal (Pt) and...
The global energy consumption has been sharply raising over the years. To sustain the energetic needs and simultaneously combat the harmful use of pollutants, it is necessary to resort on efficient green energy sources with the possibility of storing their products. Photoelectrochemical (PEC) cells relies on semiconductors to convert the absorbed solar light into green hydrogen through a...
The scope of this research line is to investigate a new class of ferroelectric (FE) oxides with tuned band-gap (Eg) to address multiple photovoltaic (PV) key-mechanisms that will enable to develop a groundbreaking approach to the design of solar cells (SC): i) Eg ≤1.5 eV optimized for solar radiance absorption; ii) Non-centrosymmetric structure upholding FE Polarization (P) >50 µC/cm2 and Tc...
The Era of the IoT and the paradigm of Sustainable Energy boosted the search for self-powered devices that harvest and store energy to satisfy the electrical needs of the generation of autonomous wearable electronics.1,2 Thermally-chargeable supercapacitors are a clean energy technology that is able to convert the waste thermal energy into electrical energy (as a power source) and,...
During the past few decades, with rapid enlargement of human society, consumption of traditional energy has increased exponentially. Thermoelectric materials (TE) can generate electrical energy when they are exposed to a thermal gradient, considered one of the most important solutions for sustainable energy harvesting.[1,2] These materials present lightweight, small size, pollution free and...
