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...

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...

Nano-Confinement Induced Chain Alignment in Ordered P3HT Nanostructures Defined by Nanoimprint Lithography

Location: Dallas, United States

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...

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,

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....

Metal Nanostructures for Optical Sensing and Signaling

Location: California, United States

The aim of this research is to develop devices based upon two dimensional arrays of metallic nanoparticles, with an optical signatures that are tunable and can measure changes their environment. We have synthesized silver nanoparticles of 3-6 nm...

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...

Physicists put a new spin on electrons

Location: British Columbia, Canada

In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely constructed,...

Tiny Machines Convert Sunlight Directly into Work: Small watercraft made of nanostructured materials are propelled by sunlight

Location: California, United States

Sunlight is a major source of energy, from photovoltaics and solar-thermal units to biofuels and water-splitting. But all these technologies require intermediate steps and infrastructure to turn the sun's rays into something that can be...

Nanopore arrays combine high power and storage capacity.

Location: Maryland, United States

Abstract:

The ultimate electronic energy-storage device would store plenty of energy but also charge up rapidly and provide powerful bursts when needed. Sadly, today's devices can only do one or the other: capacitors provide...

'Wireless' Activation Of Brain Circuits

Location: Case Western Reserve University, United States

Traditionally, stimulating nerves or brain tissue involves cumbersome wiring and a sharp metal electrode. But a team of researchers at Case Western Reserve University is going "wireless."

And it's a unique collaboration...

A Better Way to Make Nano Stuff, Durable molds could serve as a practical manufacturing tool in making nano devices.

Location: Yale University, United States

Without better techniques for manufacturing nanoscale devices, many will remain in the lab. The chip industry also needs better nanoscale manufacturing techniques to create ever denser data storage and ever faster microprocessors. A technique...

Cooling Chips with Thermoelectrics: Researchers have made ultrathin refrigerators for microprocessors.

Location: California, United States

If you could remove the layers of circuitry in your computer and touch the main processor while it's running a video, you would feel its blistering heat, which can exceed 100 °C. Such heat, a natural by-product of shuttling electrons through...

Cheap, Self-Assembling Optics: Researchers have made new nano building blocks for optical computing and solar-cell coatings.

Location: Berkeley, California, United States

Researchers at the University of California, Berkeley, have created nanoscale particles that can self-assemble into various optical devices. By controlling how densely the tiny silver particles assemble themselves, the researchers can make several...

Sticky Nanotape: Carbon-nanotube adhesive outperforms gecko feet and could aid climbing robots.

Location: Georgia, United States

For years, materials scientists have been trying to catch up with geckos. Adhesives that, like gecko feet, are dry, powerful, reusable, and self-cleaning could help robots climb walls or hold together electrical components, even in the harsh...

Nanonets-To Convert Solar Energy Into Hydrogen

Location: Boston, United States

One problem with solar cells is that they only produce electricity during the day. A promising way to use the sun's energy more efficiently is to enlist it to split water into hydrogen gas that can be stored and then...

New Physical Phenomenon Seeing High Frequency Waves by Combining Molecular Dynamics Simulations of Shock Waves

Location: Lawrence Livermore National Laboratory, United States

Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of...

Study Finds Quantum Dots Nanoparticles Can Penetrate Skin Through Minor Abrasions

Location: College of Veterinary Medicine, North Carolina State University, United States

Researchers at North Carolina State University have found that quantum dot nanoparticles can penetrate the skin if there is an abrasion, providing insight into potential workplace...

New Insight in Nanotechnology by Uncovering Conductive Property of Carbon-Based Molecules

Location: Institute for NanoScience and Engineering, University of Pittsburgh, United States

University of Pittsburgh researchers have discovered that certain organic—or carbon-based—molecules exhibit the properties of atoms under certain circumstances and, in...

Silver Now Draw Star Attraction in a Series of Products from Socks to Bandages to Washing Machine

Location: American Chemical Society (ACS), United States

Nanotechnology is now available in a store near you. Valued for it’s antibacterial and odor-fighting properties, nanoparticle silver is becoming the star attraction in a range of products from socks to bandages to washing...
