Phase-changing material could allow low-cost robots to switch between hard and soft states
In the movie "Terminator 2," the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now a phase-changing material built from wax and foam, ...
The secret lives of bubbles: Mathematicians describe evolution, dissolution of clusters of bubbles (w/ video)
Bubble baths and soapy dishwater, the refreshing head on a beer and the luscious froth on a cappuccino. All are foams, beautiful yet ephemeral as the bubbles pop one by one.
Tough foam from tiny sheets
Tough, ultralight foam of atom-thick sheets can be made to any size and shape through a chemical process invented at Rice University.
New materials discovered to detect neutrons emitted by radioactive materials
Scientist Christopher Lavelle of the Johns Hopkins University Applied Physics Laboratory, together with a team of researchers from the University of Maryland and the National Institute of Standards and Technology, ...
Carbon foam: The key ingredient of a better battery?
(PhysOrg.com) -- A lighter, greener, cheaper, longer-lasting battery. Who wouldnt want that?
Why a latte is less likely to spill than a coffee
Carrying a full cup of coffee from the kitchen to the dining room can be precarious for a sleepy-eyed caffeine addict who might accidentally send a wave of java sloshing over the rim. But add a bit of foam ...
Graphene foam detects explosives, emissions better than today's gas sensors
(PhysOrg.com) -- A new study from Rensselaer Polytechnic Institute demonstrates how graphene foam can outperform leading commercial gas sensors in detecting potentially dangerous and explosive chemicals. The ...
Frogs, Foam and Fuel: Researchers Convert Solar Energy to Sugars
(PhysOrg.com) -- Engineers from the University of Cincinnati devise a foam that captures energy and removes excess carbon dioxide from the air -- thanks to semi-tropical frogs.
Building a better battery
A new battery technology provides double the energy storage at lower cost than the batteries that are used in handheld electronics, electric vehicles, aerospace and defence.
Futuristic copper foam batteries get more bang for the buck
People use their GPS apps, cameras, and mobile internet to navigate strange cities in search of good coffee, record "selfie" commentary while they wait in line, and upload their videos directly to social media sites while ...
Levitating foam liquid under the spell of magnetic fields
Foams fascinate, partly due to their short lifespan. Foams change as fluid drains out of their structure over time. It is precisely their ephemeral nature which has, until now, prevented scientists from experimentally probing ...
If space shuttle is doomed, do you tell the crew?
A NASA top official wrestled with what he thought was a hypothetical question: What should you tell the astronauts of a doomed space shuttle Columbia?
Smart foam takes aim at concussions by measuring helmet impact
Concussions in college and professional football are under the microscope more than ever these days, but they don't seem to be slowing down in frequency.
Carbon nanotubes promise improved flame-resistant coating
Using an approach akin to assembling a club sandwich at the nanoscale, National Institute of Standards and Technology (NIST) researchers have succeeded in crafting a uniform, multi-walled carbon-nanotube-based ...
