Solar energy conversion offers a solution to help mitigate global warming
Solar energy has the power to reduce greenhouse gases and provide increased energy efficiency, says a scientist at the U.S. Department of Energy's Argonne National Laboratory, in a report published in the March ...
Chemists measure chilli sauce hotness with nanotubes
Oxford chemists have found a way of using carbon nanotubes to judge the heat of chilli sauces. The technology might soon be available commercially as a cheap, disposable sensor for use in the food industry.
In world's first, atomic force microscope sees chemical bonds in individual molecules (w/ video)
(Phys.org)—IBM scientists have been able to differentiate the chemical bonds in individual molecules for the first time using a technique known as noncontact atomic force microscopy (AFM).
Harnessing the potential of quantum tunneling: Transistors without semiconductors
(Phys.org) —For decades, electronic devices have been getting smaller, and smaller, and smaller. It's now possible—even routine—to place millions of transistors on a single silicon chip.
Researchers develop holography technology that could change the way we view the world
Since the 1960s, theatergoers have shelled out for crude 3-D glasses, polarized glasses, and shutter glasses to enhance their viewing experience. These basic devices, used to trick the brain into perceiving ...
Nanophotonic switch device for routing light on a chip scale
IBM scientists today took another significant advance towards sending information inside a computer chip by using light pulses instead of electrons by building the world’s tiniest nanophotonic switch with ...
Carbon-Nanotube Toxicity Test Tricks Scientists
Nanoparticle trapped with laser light temporarily violates the second law of thermodynamics
Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In ...
High-Temp Superconducting Nanowire System is First of its Kind
'Super paper:' New nanopaper more break-resistant than cast iron
Researchers in Sweden and Japan report development of a new type of paper that resists breaking when pulled almost as well as cast iron. The new material, called "cellulose nanopaper," is made of sub-microscopic ...
Researchers find cicada wing structure able to kill bacteria on contact (w/ video)
Scientists grow ultrahigh-purity carbon nanotubes
From moths and cicadas come improvements to solar cells
Designing better solar cells might seem a question of electronics or chemistry, but for one University of Florida engineer, it starts with bugs.
