The probe of an atomic force microscope (AFM) scan air forces s a surface to reveal details at a resolution 1,000 times greater than that of an optical microscope. That makes AFM the premier tool for analyzing physical features, but it cannot tell scientists anything about chemistry. For that they tur dunk nike store n to the mass spectrometer (MS).Now, scientists at the Department of Energy鈥檚 Oak Ridge National Laboratory have combined these cornerstone capabilities into one instrument that can probe a sample in three dimensions and overlay information about the to asics outlets pography of its surface, the atomic-scale mechanical behavior near the surface, and the chemistry at and under the surface. This multimodal imaging will allow scientists to explore thin films of phase-separated polymers important for energy conversion and storage. Their results are published in ACS Nano, a journal of the American Chemical Society.鈥淐ombining the two capabilities marries the best of both worlds,鈥?said project leader Olga Ovchinnikova, who The United States delivered 50 armoured vehicles, 40 artillery pieces and 50 grenade launchers to the Lebanese army on Tuesday, part of its efforts to bolster Lebanon against a threat from militant gro stanleycup ups in neighbouring, conflict-ridden Syria.The equipment, worth $50 million, is part of an aid package that has now topped $220 million this ye adidas samba nere ar, making Lebanon the fifth-biggest recipient of American military assistance, US ambassador Elizabeth Richard said during the delivery.Fighting between Islamic State and other militant groups in Syria often flares in the mountains along Lebanon's new balance rosa northern frontier and the violence has periodically spilled across the border.Islamic State expanding foothold in Afghanistan聽Eight Islamic State suicide bombers targeted a Christian village in Lebanon near the Syrian frontier last month, killing five and raising fears of a new campaign of attacks.Fighters from Islamic State and other groups also stage regular incursions across the poorly demarcated bord
