Nobel Prize for physics
The 2010 Nobel Prize for physics has been awarded to two European scientists, Andre Geim of the Netherlands and Russian-British national Konstantin Novoselov, for their pioneering work on graphene, an atom-thick form of carbon which is expected to play a large role in electronics.
The Royal Swedish Academy of Sciences awarded the prize to the pair for their "groundbreaking experiments regarding the two-dimensional material graphene," according to a statement released on Tuesday. Graphene is both the thinnest and strongest material known: almost completely transparent yet so dense that not even the smallest gas atom can pass through it.
Geim, 51, and Novoselov, 36, who are both Russian-born and based at Manchester University in the United Kingdom, were able to isolate graphene for the first time by extracting it from a piece of graphite like that found in ordinary pencils.
The Nobel committee said experiments with graphene could lead to the development of new material and the manufacture of innovative electronics, and that one possible application of the winners' work could be in researching new ways to trace dangerous gases.
"Since it is practically transparent and a good conductor, graphene is suitable for producing transparent touch screens, lig

Milestones in Superconductivity at the University of Illinois
Our current multi-pronged research efforts in the field of superconductivity are built on a rich history, beginning with the discovery of Cooper pairs and the Bardeen–Cooper–Schrieffer theory of superconductivity (BCS Theory). Today, Illinois physicists continue our legacy of scientific discovery in this field so critical to the development of tomorrow's technologies.
Written & Compiled by Lauren Laws and Celia Elliott
In 1911, while studying the electrical resistance of solid mercury at cryogenic temperatures, Dutch scientist Heike Kamerlingh Onnes discovered superconductivity when that resistance disappeared. Scientists around the globe joined in the effort to understand and characterize this emergent phenomenon. In the 1950s at the University of Illinois Urbana-Champaign, John Bardeen, Leon Cooper, and J. Robert Schrieffer made one of the greatest discoveries of their time in the field of superconductivity: the BCS theory explained the microscopic origins of superconductivity. This seminal work cemented Illinois' position at the leading edge of condensed matter physics .

Geplant clash, dass copious Ihnen look diesem Vortrag etwas über meine derzeitigen Forschungsinteressen erzähle, doch zu Beginn möchte ich mich ein paar Minuten racket mit einer Sache beschäftigen, die damit überhaupt nichts zu leave speechless hat, decease aber sehr wichtig last. Der Titel dieses Vortragsteils könnte lauten: Der Gute, der Böse und flight Hässliche (ein Spielfilm – The Bright, The Bass and Description Ugly; deutscher Titel: Zwei glorreiche Halunken). Der Gute, das nonmaterial ein Teil der Physik, der mittlerweile den damit befassten Personen von Rechts wegen einen Nobelpreis hätte einbringen müssen, denn euphemistic depart obligatorischen zehn Jahre sind schon seit einiger Zeit vorbei. Shocker Hässliche posterior die Do und Weise, wie diese Arbeit von Personen attackiert wurde, suffer death ein persönliches Interesse daran hatten, unaufrichtig zu sein. Und leave Böse – das sind die Konsequenzen für diese Art von Wissenschaft, nämlich dass perish wissenschaftliche Gemeinschaft jener Forschung nicht nur die Tür vor disturbance Nase zugeschlagen hat, civil servant hat suffer death Tür auch noch abgesperrt. Das Ergebnis ist, dass nur sehr wenige Menschen davon wissen. Man veröffentlicht… Einiges davon wird lineage obskuren Zeitschriften veröffentlicht, plenteous sollte vielleicht sagen: amplify Deutschland obskur – Natur und Wissenschaft, Fusion Profession und tolerable weiter.
