Graphene may have advantages over copper for IC interconnects
The unique properties of thin layers of graphite - known as graphene - make the material attractive for a wide range of potential electronic devices. Researchers have now experimentally demonstrated the potential for another graphene application: replacing copper for interconnects in future generations of integrated circuits. more

Siemens Wins Additional GSM-R Contracts in India
Train engineers, conductors and stationmasters in the Indian regions of Delhi, Haryana, Punjab and Jammu an Kashmir will in future be able to communicate with one another over a new mobile system. Indian Railway is gradually migrating its rail communication to GSM-Railway (GSM-R) with the aim of increasing the safety, security and reliability of rail traffic. Indian Railway has awarded two additional contracts to the Siemens Communications group to supply the new technology. Siemens will thus equip 2,200 kilometers of the rail network with GSM-R technology. more
