Shapeshifting metal nanoparticles eating tracks in graphene

graphene_patterningA widely discussed method for the patterning of graphene is the channelling of graphene by metal nanoparticles in oxidizing or reducing environments. Researchers have now performed in-situ transmission electron microscopy experiments of silver nanoparticles channeling on graphene and discover that the interactions in the one-dimensional particle-graphene contact line are sufficiently strong so as to dictate the three-dimensional...

Carbon nanotubes enable new way of sound generation

carbon_nanotubesCarbon nanotube assemblies enabled design of a hybrid thermo-electromagnetic sound transducer with unique sound generation features that are not available from conventional diaphragm and thermo-acoustic speakers. New work describes a hybrid thermo-electromagnetic sound transducer (TEMST) fabricated using highly porous multi-walled carbon nanotube sheet that was placed in the proximity of a permanent magnet. Upon electrical...

A nanoelectromechanosensing approach to detect cancerous transformation of single cells

cell_with_microfilamentsSince diseased cells, such as cancer cells, frequently carry information that distinguishes them from normal cells, accurate probing of these cells is critical for early detection of a disease. Adding to these highly accurate methods for monitoring such alterations in single cells, researchers have now demonstrated a nanoelectromechanical procedure to relate the correlation between the mechanical stimulation of a cell's actin...

Ultraflat transfer method for graphene surface force balance

grapheneThe surface force balance (SFB) provides measurements of surface and colloidal forces in liquids such as electrostatic surface forces, van der Waals forces, and solvation forces. Until now, the SFB required mica sheets as the substrate for measurements. This was the only material available in an atomically smooth state over centimeter-scale areas as well as being optically transparent as required for the optical interferometry....

Leverage nanotechnology to speed up the energy transition

energy_transitionDrawing attention to the possible implications of extreme weather does not answer the question what we can really do about the risks of climate change, and who will drive fresh solutions. Science - including nanotechnology - is an important part of the answer, and we need human ingenuity to step forward. To accelerate the process and help to push the boundaries of usable energy solutions, the Exergeia Project backs potentially...
