Cold Sintering of Functional Materials
IEEE Distinguished Lecture
Materials Research Institute, The Pennsylvania State University, Univ Park, USA
Cold Sintering involves a transient phase that permits the densification of particulate materials at low temperatures 300 ºC and below. Sintering at such low temperature offers so many new opportunities. It permits the integration of metastable materials that would typically decompose at high temperatures. So cold sinter enables a platform for better unification of material science. Now ceramics, metal and polymers can be processed under a common platform in one step processes. With controlling the forming process new nanocomposites can be fabricated. Polymers, gels and nanoparticulates can be dispersed, interconnected and sintered in the grain boundaries of a ceramic matrix phase. With the ability to sinter metal phases, multilayer devices can be co-sintered with electrodes made from metals such as Al, Ag, Fe and Cu. With appropriate binder selection, polypropylene carbonate and its de-binding at 130 ºC we can remove organic binders and leave metals and other more stable polymers within the layers that then can be co-sintered under the cold sintering process and form unique combinations of materials in multilayers. This talk will cover some of the fundamentals of cold sintering, as well as some new examples of this technology across different material systems, ranging from ferroelectrics, semiconductors, and battery materials.

The Scientist I Like to Talk About
Andrés Castellanos, Ricardo García, José Ángel Martín Gago, Marcos Zayat
Instituto de Ciencia de Materiales de Madrid
As every year, the ICMM dedicates February’s Colloquium to celebrate 11th February, the International Day of Woman and Girl in Science. This year 4 male researchers of our institute will talk about the research work developed by noticeable female scientists in different fields: Rosalind Franklin (Chemistry and Crystallography), Margarita Salas (Biochemistry), Mildred Dresselhaus (Physics and Nanotechnology), Rita Levi-Montalcini (Neurology) and Petra Rudolf (Solid-state Physics).
With this colloquium the ICMM wants to subscribe the multiple initiatives that are going to take place these days in the world with a common goal: tackling and removing the gender barriers at the technological and scientific fields while promoting the gender equality in the personal growth.

From the origin of the Universe to the detection of exoplanets: The Nobel Prize in Physics 2019
J. Miguel Mas Hesse
Centro de Astrobiología (CSIC-INTA)
The Royal Swedish Academy has decided to award the Nobel Prize in Physics 2019 to three scientists working in different topics, from the Origin of the Universe to the Planets orbiting around other stars. James Peebles made very relevant and direct participation to the prediction of the properties of the Cosmic Microwave Background (CMB) produced after the Big Bang, and specifically to the identification of its anisotropies as the seed from the big structures of the actual Universe were emerged. This CMB would be discovered by R. Penzias y A. Wilson in the middles ’60s of the XXth century. On the other hand, in 1995, Michel Mayor and his Ph.D. student, at that time, Didier Queloz, discovered the first planet orbiting around a Solar-type star. There was a conviction about the existence of planetary systems similar to our solar system but it wasn’t until the Mayor and Queloz work that this issue was proved.
Nowadays, more than 4000 exoplanets are known, a lot of them with conditions that could allow a life analogous to the one on Earth, and their detection will be the main goal in the next 10 years.
In this seminar, we will review the advances in both research fields and their impact on the development of Knowledge. Besides being very different results, both fields provide a new perspective on the place that humans have in the Cosmos.
