Can superconducting rings provide clues to the early development of the universe?

Location: Nepoli, France

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...

Shifting entropy elsewhere : New methods for lowering the entropy of ultracold gases may allow observation of more subtle quantum materials.

Location: Berkeley, United States

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...

Illuminating molecules from within : Calculations show that with new short pulse x-ray light sources, it should be possible to use photoelectron emission to make movies of changes in molecular structure.

Location: Berkeley, United States

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,...

Confinement of Electrons to Diamond Isotopes : Super lattice structure realized using only carbon

Location: Tsukuba, Japan

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...

A better way to pinpoint underground oil reserves : CEE mapping technology could make extraction more efficient

Location: Cambridge, United States

An accurate map of a large underground oil reservoir that can guide engineers' efforts to coax the oil from the vast rocky subsurface into wells where it can be pumped out for storage or transport.

Researchers in MIT's Department of...

Physicists discover surprising variation in superconductors : Work may lead to understanding of new class of materials

Location: Cambridge, United States

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....

Electrically Measuring Method for a Quantum State of a Semiconductor Artificial Molecule : Applications in quantum information processing are expected

Location: Tsukuba, Japan

Background and history of research:

As electronic commerce increases in popularity and information security management at work and at home becomes more critical, there is a growing need to improve encryption technology for open...

Enlisting microbes to solve global problems : Researchers harness bacteria to produce energy, clean up environment

Location: Cambridge, United States

In the search for answers to the planet's biggest challenges, some MIT researchers are turning to its tiniest organisms: bacteria.

The idea of exploiting microbial products is not new: Humans have long enlisted bacteria and yeast to...

More power from bumps in the road : energy-harvesting shock absorbers

Location: Cambridge, United States

A team of MIT undergraduate students has invented a shock absorber that harnesses energy from small bumps in the road, generating electricity while it smoothes the ride more effectively than conventional shocks. The students hope to...

New rocket aims for cheaper nudges in space : Plasma thruster is small, runs on inexpensive gases

Location: Cambridge, United States

Satellites orbiting the Earth must occasionally be nudged to stay on the correct path. MIT scientists are developing a new rocket that could make this and other spacecraft maneuvers much less costly, a consideration of growing importance as...

Knowing when to fold : Engineers use 'nano-origami' to build tiny electronic devices

Location: Cambridge, United States

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....

Re-engineered battery material could lead to rapid recharging of many devices : Beltway for electrical energy solves long-standing problem

Location: Cambridge, United States

MIT engineers have created a kind of beltway that allows for the rapid transit of electrical energy through a well-known battery material, an advance that could usher in smaller, lighter batteries -- for cell phones and other devices -- that...

Nanospheres on a Silver Platter

Location: IL , United States

Illinois researchers in the Department of Materials Science and Engineering--post-doctoral fellow LinLin Wang and

Manufacturing inefficiency : Study sees 'alarming' use of energy, materials in newer manufacturing processes

Location: Cambridge, United States

Modern manufacturing methods are spectacularly inefficient in their use of energy and materials, according to a detailed MIT analysis of the energy use of 20 major manufacturing processes.

Overall, new manufacturing systems are...

New virus-built battery could power cars, electronic devices

Location: Cambridge, United States

For the first time, MIT researchers have shown they can genetically engineer viruses to build both the positively and negatively charged ends of a lithium-ion battery.

The new virus-produced batteries have the same energy capacity and...

Wearable blood pressure sensor offers 24/7 continuous monitoring :Device could help diagnose hypertension, heart disease

Location: Cambridge, United States

High blood pressure is a common risk factor for heart attacks, strokes and aneurysms, so diagnosing and monitoring it are critically important. However, getting reliable blood pressure readings is not always easy.

Visits to the...

Development of Thin-film Electroluminescent Device Using Inorganic Oxides

Location: Tokyo, Japan

The thin-film EL devices use perovskite oxides, typified by barium titanate (BaTiO3), which has long been used as capacitor material for electronic circuits. With an emission starting voltage of ≈10 V AC, the power source...

Tracking the trash:garbage impacts the environment

Location: California, United States

What if we knew exactly where our trash was going and how much energy it took to make it disappear? Would it make us think twice about buying bottled water or "disposable" razors?

A team of MIT researchers today announced a major...

A fabric with vision:Flexible lensless camera from web of light-detecting fibers

Location: Cambridge, United States

Imagine a soldier's uniform made of a special fabric that allows him to look in all directions and identify threats that are to his side or even behind him. In work that could turn such science fiction into reality, MIT researchers have...

Solar Cells with Self-assembled Nanowires

Location: Seattle, United States

A single hour of sunlight contains enough energy to meet global energy consumption for an entire year. With demand for energy on the rise and environmental pollution an increasing concern, scientists are exploring new ways to harness the sun's...
