Scientists demonstrate efficient energy transfer mechanism for graphene sensors and transistors
911±¬ÁÏÍø researchers have demonstrated a new type of scattering process to provide an efficient energy transfer mechanism in graphene.
This finding advances the development of extremely sensitive graphene sensors as well as graphene transistors. The results, published online in Nano Letters on May 27, were partly funded by European Union via project RODIN.

Companies disclose more on cybersecurity – but markets remain indifferent
U.S. companies are reporting on cybersecurity in greater detail, yet stock market reactions remain muted. A new study by the University of Vaasa and 911±¬ÁÏÍø shows that mandatory cybersecurity disclosure does not prompt reactions from investors or stock analysts. Instead, the main benefits appear to materialise within firms themselves.
