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...

The Municipal Solid Waste Landfill as a Source of Montreal Protocol-restricted Halocarbons in the United States and United Kingdom

Location: Cambridge, United States

Abstract

Central to the study of stratospheric ozone recovery and climate change, is the ability to predict emissions of Montreal Protocol-restricted halocarbons (MPGs) over the coming decades. The prediction of emissions has become...

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...

Formation of Ozone and Growth of Aerosols in Young Smoke Plumes from Biomass Burning

Location: Cambridge, United States

The combustion of biomass is a major source of atmospheric trace gases and aerosols. Regional- and global-scale models of atmospheric chemistry and climate take estimates for these emissions and arbitrarily "mix" them into grid boxes...

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,

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,...

Adaptive Fuzzy-Artificial Neural Network Based Speed Controller of DC Motor Drive

Location: Khulna, Bangladesh

This Research introduces a DC motor drive system with a fuzzy-artificial neural-network controller. First, a neural network-based architecture is described for fuzzy logic control. The characteristic rules and their membership functions of...

Using carbon nanotubes to detect nitric oxide : New sensor could reveal nitric oxide's role in living cells

Location: Cambridge, United States

Source: "The rational design of nitric oxide selectivity in single-walled carbon nanotube near infrared fluorescence sensors for biological detection"
Jong-Ho Kim et al
Nature Chemistry

Results: A...

Robots swim with the fishes : New robots mimic fish's swimming, could be used in underwater exploration

Location: Cambridge, United States

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...

Pushing the envelope of general relativity

Location: Tokyo, Japan

Einstein introduced general relativity in the early 20th century, and since then it has been proven to be an accurate description of gravity beyond the regime of validity of Newtonian gravitation. Since then, people have been asking...

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...

Robo-forklift keeps humans out of harm's way : Could allow military to handle supplies without risk to people

Location: Cambridge, United States

Researchers in MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) are working on a better way to handle supplies in a war zone: a semi-autonomous forklift that can be directed by people safely away from the dangers of the...

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...

Stuck in the middle : research explains how thin layers of tiny organisms form at sea; work could help predict harmful algal blooms like red tide

Location: Cambridge, United States

Not far beneath the ocean's surface, tiny phytoplankton swimming upward in a daily commute toward morning light sometimes encounter the watery equivalent of Rod Serling's Twilight Zone: a sharp variation in marine currents that traps...
