A group made by Politecnico di Milano researchers, thanks to the use of extremely short light pulses, has observed for the first time the motion of the electrons in an amino acid, the phenylalanine. The research work ("Ultrafast electron dynamics in phenylalanine initiated by attosecond pulses"), carried out in collaboration with researchers from the Universidad Autónoma di Madrid, the Queen’s University of Belfast, the Università di Trieste and the Institute of Photonics and Nanotechnologies IFN-CNR of Milano and Padova, has been published on the prestigious Science international magazine. The research work is based on an attosecond technology developed during the last years by the research group of the Politecnico Physics Department led by Professor Mauro Nisoli.
Nature magazine has published a study entitled "Limited impact on decadal-scale climate change from increased use of natural gas", born thanks to the cooperation among five different countries’ research centers. From the Italian side, Massimo Tavoni (Professor at Politecnico) and Giacomo Marangoni (PhD Politecnico student), both of them researchers at the Euro-Mediterranean Center on Climate Change.
The article analyses the links between the availability of natural gas and the global warming problem and it shows how a natural gas expansion won’t slow down climate changes if policies aimed at reducing greenhouse gas emissions are not adopted as well.
