New blueDrive Photothermal Excitation for Asylum Research Cypher AFMs uses a modulated blue laser to directly drive the cantilever during AC mode imaging, producing an ideal frequency and phase response.
AC modes typically rely on piezoacoustic drive, which in liquid produces an obviously distorted and time-varying response. In air, the high Q of the lever can mask the problem, but it still interferes with quantitative analysis.

Lithium-oxygen (Li-O2) batteries are a new type of experimental battery that electric car manufacturers are hoping will address the issue of limited driving range. Unlike the lithium-ion batteries used today, lithium-oxygen batteries do not require metal oxide cathodes to produce electrochemical power, instead generating power from reactions with oxygen in the atmosphere. The significant weight savings realized through this design could potentially boost energy densities of batteries by up to four times. However, lithium-oxygen batteries have yet to leave the laboratory due to short battery lifespans caused by parasitic side reactions and accumulated charge polarization at battery cathodes.

Researchers at the Georgia Institute of Technology have "painted" the world's most famous painting Mona Lisa on a substrate surface approximately 30 microns in width - or one-third the width of a human hair. The team's creation, the "Mini Lisa," demonstrates a technique that could potentially be used to achieve nanomanufacturing of devices because the team was able to vary the surface concentration of molecules on such short-length scales.

Following traumatic injury, skin has the capacity to repair itself through complex biochemical changes. The dermis is remodeled over time affecting its mechanical behavior. AFM nanoindentation showed that the scar tissue exhibits stiffer behavior than healthy skin. Scar tissue shows weaker visco-elastic creep and reduced capability to dissipate energy at physiological frequencies than adjacent intact skin. AFM imaging showed a distinct orientation of collagenous fibrils in the scar tissue.

A high-power atomic force microscope that could revolutionize the study of materials at high temperatures and pressures is coming into focus in a Wright State University lab. Steven Higgins and his team are building a new version of the hydrothermal atomic force microscope, an instrument that could unlock scientific mysteries and be used in the study of oil production, hydrofracturing of rock layers, storage of radioactive waste and the capture and storage of atmospheric carbon dioxide.
