HEADLINES ARCHIVE
Polymer Is Body Heat Activated to Shape-Shift
Key to creating the material was the ability to tune the trigger temperature.
Researchers Use Hybrid Technology to Create Biorenewable Nylon
The material has an extra double bond in its backbone which can be used to customize the material’s mechanical properties.
"Green" Propellant Could Fuel Rockets
The propellant is based on ammonium dinitramide, a high-energy salt.
Microwaved Nanotubes Come Up Clean
Treating the nanotubes in a household microwave burns off the amorphous carbon.
Tests Confirm Viability of Lithium-Air Battery
Lithium-air batteries could store electricity at up to five times the energy density of lithium-ion batteries.
Innovative Way to Print 3D Metals and Alloys
The method bypasses the powder bed and energy beam approach and uncouples the two-step process of printing the structure and fusing its layers.
Chemical "Fingerprint" Identifies Bogus Spanish Spice
Analysis revealed that 26 of 44 samples were neither grown nor processed in Spain.
Sulfur-Based Concrete for Martian Shelters
The concrete uses a soil simulant created by NASA in place of gravel, and molten sulfur in place of water.
Vertical Charge Transport Achieved in Semiconducting Polymer
The researchers say the process is easy to replicate and inexpensive, opening the door to applications in organic opto-electronic devices and more.
Biofuel Production from CO2
The method purifies carbon dioxide from flue gases by absorbing it into a liquid, which is pumped through fiber membranes that can be immersed into microalgae beds.
The Maker Revolution Gains Traction
The step toward individual fabrication represents something of a revolution that has the potential to rival earlier revolutions in digital communication and computation.
DOE to Explore Nuclear Waste Disposal at North Dakota Site
The test will provide insight into challenges such as drilling techniques, subsurface characterization and wellbore stability and sealing.
Partial Water Pipe Replacement Ups Health Risk: Study
If pipe replacements are to be done in response to lead contamination, half measures can create a greater problem than doing nothing, researchers say.
Bio-Inspired Self-Cleaning Window Is Developed
The window uses nanostructures that amplify the thermochromic properties of a coating applied to the glass to cut glare, save energy and enable self-cleaning.
Crude Oil Prices Are Making It Tough on Recyclers
With the cost of a barrel of crude at January 2003 prices, recyclers can’t compete with the cost to produce virgin resin pellets.
Cornell Creates Self-Assembled Superconductor
The research is an effort to achieve superconductivity at higher temperatures.
HRL Creates Process for 3D Printable Ceramics
Once fired, the material is able to withstand temperatures of 1700° C, and has almost zero porosity.
Low-Cost 3D Composites Printing Is Demonstrated
The technique uses ultrasonic waves to position millions of reinforcement fibers.
Conductive Concrete Can Melt Snow on Airport Tarmacs
If the FAA is satisfied with current tests, it will consider integrating the concrete into the tarmac of a major U.S. airport.
Electronic Sensors Monitor Brain Injury Then Melt Away
The sensors are built on sheets of silicon that are configured to function for a few weeks.
