Abstract :
Detecting trace amounts of analytes in aqueous systems is important for health diagnostics, environmental monitoring, and national security applications. Single-walled carbon nanotubes (SWNTs) are ideal components for both the sensor...

Watching a metal transform into a superconductor, it may not be obvious that
this transition provides access to some of the same physics that governed the
cooling of the universe following the Big Bang. Yet at the root of both of these...

Ultracold atoms are still too hot. This may seem a ridiculous claim—after
all, the low-temperature exploits of the purveyors of quantum gases are
notorious. Laser cooling can flash-freeze atoms to temperatures in the micro-
and nanokelvin...

Abstract :
Resolving individual atoms has always been the ultimate goal of
surface microscopy. The scanning tunneling microscope images
atomic-scale features on surfaces, but resolving single atoms...

In the 2,000 or so years since the Roman Empire employed a naturally
occurring form of cement to build a vast system of concrete aqueducts and other
large edifices, researchers have analyzed the molecular structure of natural
materials and...

Control of polymer morphology and chain orientation is of great importance in
organic solar cells and field effect transistors (OFETs). Here we report the use
of nanoimprint lithography to fabricate large-area, high-density, and ordered...

Much of our knowledge about molecular structure and reactivity is based on
interpreting how molecules interact with light. In particular, time-resolved
pump-probe studies where a first “pump” laser pulse initiates a dynamical
event,...

Borrowing from Mother Nature, a team of MIT researchers has built a school of
swimming robo-fish that slip through the water just as gracefully as the real
thing, if not quite as fast.
Mechanical engineers Kamal Youcef-Toumi and Pablo...

Among all available materials, diamond has the optimal characteristics with
respect to hardness, thermal conductivity, light transmission wavelength range,
and chemical stability. Furthermore, as a semiconducting material, diamond shows...

MIT physicists have discovered that several high-temperature superconductors
display patchwork quilt-like variations at the atomic scale, a surprising
finding that could help scientists understand a new class of unconventional
materials....

Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed
to electronic circuits and strength to materials like carbon composites, used in
airplanes and racecars. A major problem, however, is that the metals used to

Folding paper into shapes such as a crane or a butterfly is challenging
enough for most people. Now imagine trying to fold something that's about a
hundred times thinner than a human hair and then putting it to use as an
electronic device....

MIT engineers are using carbon nanotubes only billionths of a meter thick to
stitch together aerospace materials in work that could make airplane skins and
other products some 10 times stronger at a nominal increase in cost.
Moreover,...

New research findings at MIT could lead to microchips that operate at much
higher speeds than is possible with today's standard silicon chips, leading to
cell phones and other communications systems that can transmit data much faster. ...
