Metal foam obliterates bullets - and that's just the beginning - 5 views

    Composite metal foams (CMFs) are tough enough to turn an armor-piercing bullet into dust on impact. Given that these foams are also lighter than metal plating, the material has obvious implications for creating new types of body and vehicle armor - and that's just the beginning of its potential uses.

Technology Review: Blogs: arXiv blog: Highlights from the Gallery of Fluid Motion - 7 views

    The best of the bunch (so far) for the 2010 American Physical Society's Gallery of Fluid Motion
    Each year, the Fluid Dynamics division of the American Physical Society holds a conference. This year, the meeting is in Long Beach, California, in November.

    One of the highlights is the impressive set of videos of fluid motion that the delegates put together. These videos have already begun to appear on the arViv in impressive numbers.

    Videos are an effective and increasingly popular way of publishing research. Expect to see more like this.

    But there are clearly better ways to make them available other than as downloads from the arXiv or as videos in a room in Long Beach. One obvious option is to make them available on streaming websites such as YouTube andVimeo. As far as I can tell, they are not available like this.

    Another is to create a website that showcases them in advance, to make it a global, web-based event. Many of the videos are superb. Not only could they command a bigger audience, they deserve it.

    If plans are afoot to make the Gallery of Fluid Motion a bigger event, then great. If not, shame!

    Here is my selection of the highlights this year.

Carbon Nanotube Speakers Could Be Powered by Lasers, Transform Noisy Spaces into Peacef... - 6 views

  • Carbon Nanotube Speakers Could Be Powered by Lasers, Transform Noisy Spaces into Peaceful Sanctums
  • “Nanotubes assemblies of various types are black and highly conductive,” said Dr. Mikhail Kozlov, a research scientist and the study’s lead author. “Their dark, conductive surface can be effectively heated with laser light or electricity to induce variations in the pressure of the air around the nanotubes — which we perceive as sound. It’s called the photo- or thermo-acoustic effect, and it’s the same principle Alexander Graham Bell used to produce sound on the first telephone.”

    With laser excitation, no electrical contact with the nanotube speaker is required, making the speakers wireless.

    “Speakers made with sheets are extremely thin, light and almost transparent,” Kozlov said. “They have no moving parts and can be attached to any surface, which makes the surface acoustically active. They can be concealed in television and computer screens, apartment walls, or in the windows of buildings and cars. The almost invisible strands form films that can ‘talk.’”

    In addition to filling a room with sound from invisible speakers, nanotube speakers could easily cancel sound from the noisiest neighbor or dim the roar of traffic rushing past a neighborhood, using the same principles as current sound-canceling technologies.

    “The sound generation by nanotube sheets can help to achieve this effect on very large scales,” Kozlov said.

    A UT Dallas team's study published in the Journal of Applied Physics expands the extraordinary capabilities of nanotechnology to include laser-powered acoustic speakers made from assemblies of carbon nanotubes.
    Amazing work being done with nanotechnology!
