Graphene : from Growth to Devices

Laurent Syavoch Bernard

We report a full study of graphene synthesis by CVD on Cu surface. Two CVD methods have been developed. The first is a static one, which yields monolayer of graphene at low pressure of methane in 3 minutes at 1000 C. The second one is an equimolar method w ...

Beer tapping: dynamics of bubbles after impact

François Gallaire, Pierre-Thomas Paul Brun, Vladislav Mantic Lugo

Beer tapping is a well known prank where a bottle of beer is impacted from the top by a solid object, usually another bottle, leading to a sudden foam overflow. A description of the shock-driven bubble dynamics leading to foaming is presented based on an e ...
