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...

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,

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...

The effect of dissolved hydrogen on spent nuclear fuel corrosion

Location: Chalmer, Sweden

Abstract :

In case of a canister failure in a deep bedrock repository for nuclear fuel, the release of radiotoxic nuclides to the groundwater will depend on the chemical environment near the fuel surface. Due to the presence of large...

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...

'Fuzzy logic' reveals cells' inner workings

Location: Cambridge, United States

Living cells are bombarded with messages from the outside world -- hormones and other chemicals tell them to grow, migrate, die or do nothing. Inside the cell, complex signaling networks interpret these cues and make life-and-death...

Spinning at the nanoscale : Electrospun fibers could be used for protective clothing, wearable power and more

Location: Cambridge, United States

MIT Professor of Chemical Engineering Gregory Rutledge keeps a small piece of fabric that at first glance resembles a Kleenex. This tissue-like material, softer than silk, is composed of fibers that are a thousand times thinner than a human...

New radio chip mimics human ear, could enable universal radio

Location: Cambridge, United States

MIT engineers have built a fast, ultra-broadband, low-power radio chip, modeled on the human inner ear, that could enable wireless devices capable of receiving cell phone, Internet, radio and television signals. Rahul Sarpeshkar, associate...

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...

Biodiesel blend performs as well as ultra-low sulfur fuel

Location: WEST LAFAYETTE, United States

ABSTRACT : Topics : Quantitative Evaluation of an On-Highway Trucking Fleet to Compare #2ULSD and B20 Fuels and Their Impact on Overall Fleet Performance A study was performed on 20 Class-8 trucks paired by make, model, mileage, and drive...

Scientists Work To Plug Microorganisms Into The Energy Grid

Location: Oak Ridge, United States

The answer to the looming fuel crisis in the 21st century may be found by thinking small, microscopic in fact. Microscopic organisms from bacteria and cyanobacteria, to fungi and microalgae, are biological factories that are proving to be...

New Possibilities for Hydrogen-Producing Algae

Location: Carnegie, United States

The single-celled green alga Chlamydomonas reinhardtii generates hydrogen by fermentation under low oxygen conditions. Cells in photo are stained with fluorescent dyes. Purple indicates DNA, green indicates flagella.

New surface coating controls biofilm growth

Location: Syracuse, United States

The new technology may lead to the development of improved medical implants

This is the tale of two biological substances—cells from mammals and bacteria. It's a story about the havoc these microscopic entities can wreak on...

Silica Algae Reveal How Ecosystems React To Climate Changes

Location: Stockholm, Sweden

A newly published dissertation by Linda Ampel from the Department of Physical Geography and Quaternary Geology at Stockholm University in Sweden examined how rapid climate changes during the most recent ice age affected ecosystems in an area...

Stem-Cell Repair Kit for Stroke

Location: London, United Kingdom

A novel matrix of neural stem cells and a biodegradable polymer can quickly repair brain damage from stroke in rats. Within just seven days of injecting the concoction directly into the damaged part of the brain, new nerve tissue grew to fill...

Nanofibers Power Attoscale Chemistry: A new way to perform experiments using just thousands of molecules.

Location: Ohio, United States

Researchers have developed a new way to perform chemical reactions involving only about 1,000 molecules. The method could prove useful in the rapid screening of chemical reactions when searching for new drugs and industrial materials.

Phase Transitions Induced by Nanoconfinement in Liquid Water: novel way to control water behavior

Location: Princeton, United States

Researchers may be able to "freeze" water into a solid, not by cooling but by confining it to narrow spaces less than one-millionth of a millimeter wide, according to new results from an interdisciplinary team of scientists and engineers. It's...

Artificial cells, simple model for complex structure

Location: Pennsylvania, American Samoa

A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a Penn State researcher. "Cells are interesting because they show organization even at the level of the cytoplasm,...

A New era of Cancer

Location: Stockholm, Sweden

Every year, millions of people are diagnosed with cancer - a remarkably high number. But what about the flipside of those statistics? That is, two out of three people never get cancer, and more than half of heavy smokers don’t get...
