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...

Using Nanotubes in Computer Chips : A new technique for growing carbon nanotubes should be easier to integrate with existing semiconductor manufacturing processes

Location: Cambridge, United States

Source: "Low Temperature Synthesis of Vertically Aligned Carbon Nanotubes with Electrical Contact to Metallic Substrates Enabled by Thermal Decomposition of the Carbon Feedstock," Gilbert Nessim, Carl V. Thompson et al, Nano...

Cement's basic molecular structure finally decoded : Robustness comes from messiness, not a clean geometric arrangement

Location: Cambridge, United States

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...

Two-dimensional conductivity at the surface of organic single crystals

Location: Delft, Germany

Molecular systems, or systems based on small organic molecules, possess interesting and useful electronic properties. The rapidly developing area of organic -or plastic- electronics is based on these materials. The investigations of...

NanoPen: Dynamic, Low-Power, and Light-Actuated Patterning of Nanoparticles

Location: California, United States

Abstract:

The ability to pattern nanostructures has important applications in medical diagnosis,(1, 2) sensing,

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...

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....

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...

Researchers make carbon nanotubes without metal catalyst : Oxides, as well as metals, seem to be able to sprout carbon nanotubes, study finds

Location: Cambridge, United States

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 grow...

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...

As planet warms, poor nations face economic chill: Climate change may widen gap between rich and poor, study finds

Location: Cambridge, United States

A rising tide is said to lift all boats. Rising global temperatures, however, may lead to increased disparities between rich and poor countries, according to a recent MIT economic analysis of the impact of climate change on growth.

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...

Finishing touches: New alloys offer alternative to chrome

Location: Cambridge, United States

Ever since the 1940s, chrome has been used to add a protective coating and shiny luster to a wide range of metal products, from bathroom fixtures to car bumpers.

Chrome adds beauty and durability, but those features come at a heavy...

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...

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...

A new approach to engineering for extreme environments

Location: California, United States

Composite materials such as fiberglass, which take on a mix of properties of their constituent compounds, have been around for decades. Now, an MIT materials scientist is taking composites to the nanoscale, where entirely new properties, not found...

Athermal Holographic Filters

Location: California, United States

Abstract: Holographic filters are used as optical sensors and in wavelength division multiplexing (WDM) filtering applications. Temperature dependence is a critical concern for telecommunications. Researcher realize the design of an athermal...

A way to slow concrete creep to a crawl

Location: Cambridge, United States

MIT civil engineers have for the first time identified what causes the most frequently used building material on earth -- concrete -- to gradually deform, decreasing its durability and shortening the lifespan of infrastructures such as bridges and...

Biomimetic-engineering design can replace spaghetti tangle of nanotubes in thermal material

Location: Cambridge, United States

Nanoelectromechanical systems (NEMS) devices have the potential to revolutionize the world of sensors: motion, chemical, temperature, etc. But taking electromechanical devices from the micro scale down to the nano requires finding a means to...
