Researchers have determined that the surface texture of gallium nitride (GaN) materials can influence the health of nearby cells. The work is significant because GaN is a material of interest for developing new devices that can control cellular behavior.
Scientists have demonstrated infrared imaging of an organic semiconductor known for its electronics capabilities, revealing key nanoscale details about the nature of its crystal shapes and orientations, and defects that also affect its performance.
In a new paper, researchers describe in great detail how to fabricate and use transparent graphene neural electrode arrays in applications in electrophysiology, fluorescent microscopy, optical coherence tomography, and optogenetics.
Silver nanoparticles have a wide array of uses, one of which is to treat drinking water for harmful bacteria and viruses. But do silver nanoparticles also kill off potentially beneficial bacteria or cause other harmful effects to water-based ecosystems? A new paper says that is not the case.
Scientists have managed to characterize theoretically the behavior of water in close vicinity to a superhydrophobic surface. Not only that, but also they have verified the analytical theory by experiment with an unprecedented precision.
Researchers have demonstrated a method to fabricate electronic devices by using DNA. The DNA itself has no part in the electrical function, but acts as a scaffold for forming a linear, pearl-necklace-like nanostructure consisting of three gold nanoparticles.
New research provides the basis for new electromechanical designs using 2D-nanocellulose. In a longer-term perspective, the reinterpretation of electrical features for hydrogen bonds here introduced could pave the way in the understanding of life-essential molecules and events.
Researchers are creating a new approach to reconstruct 3-D full-color holographic images by using just one layer of nanoscale metallic film. This work has a huge potential to change our daily lives by equipping our cell phones with 3-D floating displays and printing 3-D security marking onto credit cards.
Researchers have found a way to significantly improve computer performance. They propose the use of the so-called T-waves, or terahertz radiation as a means of resetting computer memory cells. This process is several thousand times faster than the magnetic-field-induced switching.
