Researchers improve performance of III-V nanowire solar cells on graphene
(Phys.org) —Imagine a field of small wires—standing at attention like a tiny field of wheat—gathering the Sun's rays as the first step in solar energy conversion.
Nanotube composites increase the efficiency of next generation of solar cells
Carbon nanotubes are becoming increasingly attractive for photovoltaic solar cells as a replacement to silicon. Researchers at Umeå University in Sweden have discovered that controlled placement of the carbon ...
Research team scores a first with effective thermal camouflage
Engineers and scientists have been trying to discover the ultimate "cloaking" device – not just as a hat trick to make things invisible—but for its applications in defence technology. Now, a team from the NUS Department ...
'Milking' brown recluse spiders for silk
(Phys.org) —Rabbit, a brown-recluse spider, is fastened to the proverbial treadmill in Hannes Schniepp's Nanomaterials & Imaging lab. She is restrained but relaxed. Her spinnerets are churning out exquisite ...
Pumping iron: A hydrogel actuator with mussel tone
(Phys.org) —Protein from a small, tasty mollusk inspired Michigan Technological University's Bruce P. Lee to invent a new type of hydrogel actuator.
First step towards 'programmable materials'
Researchers from Empa and ETH Zurich have succeeded in producing a prototype of a vibration-damping material that could change the world of mechanics forever. The material of the future is not only able to ...
New shrinking gel steers tooth tissue formation
A bit of pressure from a new shrinking, sponge-like gel is all it takes to turn transplanted unspecialized cells into cells that lay down minerals and begin to form teeth.
Fully compostable bioplastic made from shrimp shells
(Phys.org) —Researchers at Harvard's Wyss Institute have developed a method to carry out large-scale manufacturing of everyday objects—from cell phones to food containers and toys—using a fully degradable ...
Novel laser produces random mid-infrared light for improved imaging applications
Most lasers produce coherent light, meaning that the light waves are perfectly synchronized with each other. Spatially coherent waves, however, can interfere with one another and produce speckles in an image. ...
Optical nanocavity to boost light absorption in semiconductors
Associated with unhappy visits to the dentist, "cavity" means something else in the branch of physics known as optics.
An essential step toward printing living tissues
A new bioprinting method developed at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard School of Engineering and Applied Sciences (SEAS) creates intricately patterned ...
Researcher bringing 3-D TV back from the dead
One UCF researcher may be on the brink of bringing 3-D- TV back from the dead.
In situ bandgap tuning of graphene oxide achieved by electrochemical bias
The ability to modulate the physical properties of graphene oxide within electronic components could have numerous applications in technology, WPI-MANA scientists report
Spider silk ties scientists up in knots
Two years ago, researchers from Iowa State University (USA) published a study which concluded that spider silk conducts heat as well as metals. Now, a team from the University of the Basque Country (Spain) ...
