Aside from our scientific and technological pursuits, Graphenea strives to engage in education on a broader scale. Along this direction, Graphenea's Alba Centeno and Beatriz Alonso gave an introductory talk at the London's Imperial College Department of Materials' 5th Postdoctoral Symposium. Graphenea also sponsored a prize for the best talk.
The traditional symposium gives postdoctoral fellows an opportunity to show their research in front of their peers, either through an oral presentation or on a poster. Dr. Victoria García Rocha, an Intra-European Marie Curie Fellow, won the prize with a talk entitled “Engineering 3D Architectures From Chemically Modified Graphene”.

Dr. García Rocha works at the Centre for Advanced Structural Ceramics (CASC). CASC started in July 2008 with national EPSRC funding (£5.5M) for a five-year program. At the end of the national funding period, the research unit continued to function as an industrial consortium. The CASC, directed by Professor Eduardo Saiz Gutierrez and guided by industrial partners, has developed a significant number of active industrial collaborations both abroad and from the UK. The industrial consortium has built on CASC's early success, enabling its sustainability and continuing a long-term fruitful relationship between CASC-associated academics and the industrial structural ceramics community. Graphenea is a partner of CASC.
CASC is embedded in and draws its resources from the College's Department of Materials, which houses a large number of scientists working on a wide range of materials-related topics, including biomaterials, ceramics and glasses, engineering alloys, functional materials, nanotechnology, and theory and simulation. The department is the oldest of its kind in the UK, and houses over one hundred postgraduate students, as well as world-class facilities for material characterization.

At the core of every galaxy lies a supermassive black hole (SMBH). These behemoths are many times the size of ordinary black holes. And unlike your garden-variety stellar-mass black hole, supermassive black holes didn’t form from a collapsing star; rather, they formed.... well, we actually don’t know how they formed. But we do know just how big they are. An ordinary black hole can have about five to several tens of times the mass of the Sun (solar masses), where our own galaxy’s SMBH has about four million solar masses.
While we don’t yet know the mechanism by which SMBHs form, the prevailing thought is that they formed (relatively) small, with “only” 100 to 100,000 solar masses. They would then have gained mass over time as they gobbled up matter, ultimately growing to become the giants we see today.
A new SMBH has now been discovered with about twelve billion solar masses. By itself, that’s not unprecedented; others have been discovered with roughly the same mass. What’s astounding about the new discovery is the extreme distance of the SMBH—about 12.8 billion light-years from Earth—and hence, how quickly after the Big Bang it formed.
