Among the astonishing properties of graphene, a high mobility of the charge carriers has placed this material into the focus of intensive research efforts, aimed at developing high-speed graphene-based electronic devices. The first device of this family, a graphene field-effect transistor (GFET), still remains a promising candidate for applications in flexible electronic circuits. An essential […]
Author: Ewa N. Szlapa is a is a Ph.D. student (ITN-EJD-TCCM) at Catholic University of Leuven At the beginning of the development of chemistry as a science there was alchemy, which was considered to be a magicians’ business. An alchemist put some ingredients into the glass vessel and after some time the mixture inside could […]
The two biggest questions in Economics are, no doubt, efficiency and equality. The first means no dilapidation of resources, the second means…, well, it may mean many things: equality of opportunities, resources, access to basic goods, or equality of results, among many others. Whatever we understand by equality, there are two major problems with its […]

Single-celled amoeba uses molecular mechanisms similar to complex life The single-celled amoeba Capsaspora owczarzaki has the same molecular tools as more complex organisms to help it move through various life stages. The findings suggest multi-celled mechanisms may have been in place long before animals evolved. Science News New questions raised about Lyme disease following discovery […]
Author: Meilani Wibowo obtained her master’s degree at the University of Valencia, Spain. Currently she is a Ph.D. student (ITN-EJC TCCM) at the University of Groningen, the Netherlands, where she works on the improvement of organic photovoltaic devices. Solar energy as one of the alternative and sustainable energy sources has a potential to replace fossil […]
This year the Nobel Prize in Chemistry has been awarded to Jean-Pierre Sauvage, Fraser Stoddart and Ben Feringa “for the design and synthesis of molecular machines” . These devices, often described as the tiniest “Lego” , a re indeed so small that is difficult to grasp their size used as we are to the macroscopic […]
Author: Tommaso Francese is a Ph.D. student (ITN-EJD-TCCM) at Universitat de Barcelona Every year the amount of data produced is of the order of magnitude of the Avogadro’s constant, thus 6.028×10 23 . Let’s say that it is more or less the quantity of hydrogen atoms contained in 1 gram. This trend is supposed to […]

Busy cells on the move in babies’ brains observed Neurons move through babies’ brains to where they are needed most in the first few months after birth, and these movements have now been seen by researchers. Researchers say the cells are most active in newborns, with activity slowing when the babies are about 5 months […]
Autism spectrum disorders are a group of developmental disorders that cause lifelong disabilities. They affect people’s ability to communicate, to interact with others and to understand social cues. Affected persons have difficulties recognizing body language, making eye contact, and understand other people’s emotions, symptoms that hurt the individual’s ability to function socially, at school or […]
Running is an activity that humans have held for millennia. It has been a tool, a hobby or a fashion rose by needs, crisis, culture or marketing campaigns. Today, in a busy and sedentary society aware that to maintain health it is necessary to move the ass, running has become again a major way of […]
