The structure - a layer of graphite flakes and an underlying carbon foam - is a porous, insulating material structure that floats on water. When sunlight hits the structure's surface, it creates a hotspot in the graphite, drawing water up through the material's pores, where it evaporates as steam.

A new study from MIT materials scientists reveals that gold nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons. They describe in detail the mechanism by which these nanoparticles are able to fuse with a membrane.

Nearly all electronics require devices called oscillators that create precise frequencies - frequencies used to keep time in wristwatches or to transmit reliable signals to radios. For nearly a century, these oscillators have relied upon quartz crystals to provide a frequency reference, much like a tuning fork is used as a reference to tune a piano. A new approach could ultimately replace the quartz crystal frequency reference - technology in use since the 1920s.

Researchers have demonstrated that an array of novel gold, pillar-bowtie nanoantennas can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light. A standard optical microscope acts as a 'nanocamera' whereas the pillar-bowtie nanoantennas are the analogous film.
