IFIMUP’s Research highlighted in Nanowerk
João Horta and colleagues found that size-confinement - going from macroscopic bulk samples towards nanoparticles - leads to drastic changes in the atomic structure of certain magnetocaloric materials: The change from positive thermal expansion at the macroscale towards a negative thermal expansion (NTE) at the nanoscale. NTE materials are of increasing technological interest mostly because of the idea of mixing them with a symmetric negative. This surprising size-confinement effect of magnetocaloric materials was recently highlighted in Nanowerk and the work published in Physical Review B.

António Moreira dos Santos, instrument scientist at the ORNL, visited IFIMUP
IFIMUP recently welcomed Dr. António Moreira dos Santos, a Instrument Scientist at the Oak Ridge National Laboratory (ORNL). Dr. António Santos holds a degree in Materials Engineering by the Universidade Nova de Lisboa and a PhD in Experimental Condensed Matter Physics from the University of California Santa Barbara. Currently, he is one of the instrument scientists responsible for several diffraction techniques at ORNL, including, for instance, the Spallation Neutrons and Pressure diffractometer, dedicated to perform neutron scattering studies under high pressure conditions at the ORNL Spallation Neutron Source facility. His visit to IFIMUP was carried out within the framework of his participation in the research project “Functional Lattice Instabilities in naturally layered Perovskites” (POCI-01-0145-FEDER-029454), which is led by Dr. Armandina Maria Lima Lopes, a Senior Researcher at IFIMUP. During his visit, Dr. Antonio Santos also gave a seminar entitled "Condensed Matter Research at the ORNL's Neutron Sources", in which he discussed the type of scientific research that is carried out at the ORNL by using distinct characterization techniques based on neutron scattering and how one can apply for beam time.
Seminar abstract:
“Neutron scattering is a unique tool in materials sciences. It allows studies on problems mostly inaccessible through other techniques, such as direct interrogation on the location of light elements, unveiling complex magnetic structures, or the non-destructive testing of large engineering parts. Unlike visible light (Lasers) and X-rays, neutrons beams for materials research can only be produced in dedicated facilities, such as nuclear reactors or spallation sources. The Oak Ridge National Laboratory is unique in that it houses both neutron sources, the Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR), making it arguably the leading laboratory in the world for neutron scattering research. These facilities enable investigations over a broad range of materials, in the form of powders, glasses and single crystals. Here we will illustrate the promise of neutron diffraction to physics and chemistry research. We will show examples comprising, for example, magnetic phase diagrams in lanthanides, phase competition in manganites and structural studies of clathrate hydrates. These examples will highlight how the use of the neutron scattering can assist in pursuing exciting science. Finally, ongoing improvements and additions to the SNS capabilities will be discussed: facility capabilities, instrument improvements and new sample environment devices that open a new frontier in neutron scattering.”

IFIMUP’s research on the national news
Last week Exame Informática, the television segment from the national cable channel SIC Notícias, featured the research being made on the project “MindTheGap - Decoding and bridging somatosensory information in the spinal cord”, a collaboration between i3S, IFIMUP and INESC-MN. Paulo Aguiar, i3S researcher and project leader, revealed a new meaning for the expression "mind the gap". The ambitious goal of the project is to try to better understand how the sensory information is coded and decoded by the neurons in the spinal cord, which is one of nature's best kept secrets. One of the objectives is to reverse pathologies, such as chronic pain and spinal cord injuries, without using drugs. For that they use microelectrode arrays to electrically induce controlled activity in neurons. Furthermore, they are considering flexible devices that facilitates the development of prostheses able to communicate with neurons. The complete video (in Portuguese) can be seen below.

IFIMUP’s research in the news
Dr. João Ventura talked with the Portuguese Lusa News Agency about the work developed on a more efficient and fluid free magnetic refrigerator. He told that the prototype aims to transfer heat and cold more efficiently and without fluids, using a thermal switch. This research is within the FCT project “Magnetocaloric refrigerators based on highly efficient thermal switches”, which started six months ago following a previous work, involving researchers from FCUP and the Faculty of Engineering of the University of Porto (FEUP), which resulted in a provisional national and European patent. He further explained that in magnetic refrigerators (fridges) a fluid is needed to carry the cold to the food and transports the heat from the food to the outside. It is this fluid that they want to remove from the magnetic refrigerator, since it greatly decreases efficiency. The solution is the use of a solid material as a thermal switch. While the use of fluids in magnetic refrigeration implies that the frequency (the number of cooling cycles) of operation of these refrigerators is low, and this low frequency decreases efficiency, the thermal switches allow to increase the frequency and thus, to increase the efficiency of the equipment. Magnetic cooling can reduce energy consumption by up to 35%, which benefits the environment and the citizen, since the refrigeration sector accounts for about 17% of the world's total electricity consumption. They further have the collaboration of the English company Camfridge, that has accepted to be their consultant because it is interested in the technology to change its prototypes and incorporate the technology into new magnetic refrigerators. The “Thermal Switch” project was one of the 17 European patent applications with a "seal" of the University of Porto, in the context of which the video below was made. The complete text in Portuguese from the national newspaper Diário de Notícias can be seen here.
