Goal of nanoscale optical imaging gets boost with new hyperlens
Scientists at the University of California, Berkeley, have developed a "hyperlens" that brings them one major step closer to the goal of nanoscale optical imaging. The new hyperlens, described in the Feb. 23 ...
Electromechanical imaging in liquid environments: a pathway toward molecular-level resolution of biological systems
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 ...
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.
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 ...
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
Researchers find cicada wing structure able to kill bacteria on contact (w/ video)
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.
New Organic Gold-Nanoparticle Memory Device
Capturing wasted electricity with triboelectric generators
(Phys.org) —With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps ...
Beyond the Moore's Law: Nanocomputing using nanowire tiles
An interdisciplinary team of scientists and engineers from The MITRE Corporation and Harvard University have taken key steps toward ultra-small electronic computer systems that push beyond the imminent end ...
