Graphene Puts Nanomaterials In Their Place

Nanomaterials offer unique optical and electrical properties and bottom-up integration within industrial semiconductor manufacturing processes. However, they also present one of the most challenging research problems. In essence, semiconductor manufacturing today lacks methods for depositing nanomaterials at predefined chip locations without chemical contamination. We think that graphene, one of the thinnest, strongest, most flexible and most […]

Ocean Carbon Imaged on the Atomic Scale

Dissolved Ocean Carbon (DOC) in the ocean is one of the largest pools of reduced carbon on Earth. It’s about 200 times larger than the living biosphere and comparable in size to the atmospheric CO2 reservoir.  Due to its complexity, less than 10 percent of dissolved organic carbon has been characterized.  It’s important to understand […]

IBM Scientists Measure the Energy Levels of Single Molecules on Insulators

Our understanding of single-molecule electronics has become clearer and the answer involved using a common household item – salt. Building off of a previous paper in 2009, where IBM scientists and collaborators demonstrated the ability to measure the charge state of individual atoms using noncontact atomic force microscopy (AFM), they have now taken it a […]
