A team of researchers has developed a new way to control and measure atoms that are so close together no optical lens can distinguish them. • Email to a friend • Taking advantage of its piconewton force and sub-nanometer displacement resolution, atomic force microscopy (AFM) is uniquely suited to measure nanoscale mechanical properties, especially when it comes to soft materials. Force spectroscopy is a useful nanomechanical technique to obtain both single point measurements and maps of important mechanical properties such as stiffness and adhesion. Cantilever and tip calibrations coupled with contact mechanics models enable the full analysis and interpretation of individual force curves. • Email to a friend • Scientists used photoacoustic spectroscopy applied to background-free analyses to measure unprecedentedly small trace gas concentrations. • Email to a friend • In a process they call ACDC, researchers expose plastic waste to around eight seconds of high-intensity alternating current, followed by the DC jolt. The products are high-quality turbostratic graphene, a valuable and soluble substance that can be used to enhance electronics, composites, concrete and other materials, and carbon oligomers, molecules that can be vented away from the graphene for use in other applications. • Email to a friend • |
