Researchers map path to quantum electronic devices

A team of Duke University engineers has created a master "ingredient list" describing the properties of more than 2,000 compounds that might be combined to create the next generation of quantum electronics devices.

Creating nanostructures from the bottom up

Microscopic particles are being coaxed by Duke University engineers to assemble themselves into larger crystalline structures by the use of varying concentrations of microscopic particles and magnetic fields. These nanoscale crystal structures, which until now have been difficult and time-consuming to produce using current technologies, could be used as basic components for advanced optics, data storage, and bioengineering.

Computer-designed molecules point to new therapy for cystic fibrosis

By developing software that uses 3D models of proteins involved in cystic fibrosis, a team of scientists at Duke University has identified several new molecules that may ease the symptoms of the disease.

Process makes polymers truly plastic

Process makes polymers truly plastic

Just as a chameleon changes its color to blend in with its environment, Duke University engineers have demonstrated for the first time that they can alter the texture of plastics on demand, for example, switching back and forth between a rough surface and a smooth one.

Unwinding nature’s clocks, with $14M from DARPA

From the time we eat breakfast to when we leave work, mechanical clocks control a large part of our lives. But we, and other creatures, also have biological clocks that regulate just about every function in our bodies. Scientists know our biological clocks are coordinated, but they aren't sure how. Using a $14 million grant from DARPA, a team from Duke and other universities will be looking more closely at the timepieces that drive life.

Exotic material boosts electromagnetism safely

By using exotic man-made materials, scientists from Duke University and Boston College believe they can greatly enhance the forces of electromagnetism (EM), one of the four fundamental forces of nature, without harming living beings or damaging electrical equipment.

Electron's negativity cut in half by supercomputer

Electron's negativity cut in half by supercomputer

While physicists at the Large Hadron Collider smash together thousands of protons and other particles to see what matter is made of, they're never going to hurl electrons at each other. No matter how high the energy, the little negative particles won't break apart. But that doesn't mean they are indestructible. Using several massive supercomputers, a team of physicists has spilt simulated electron perfectly in half.

Stress causes clogs in coffee and coal

Scientists still aren't sure what causes clogs in flowing macroscopic particles, but new experiments suggest that when particles undergo a force called shear strain, they jam sooner than expected. Nuts, coffee and coal inherently produce this type of movement, but many hoppers and other dispensers aren’t engineered for it.

Elemental 'cookbook' guides efficient thermoelectric combinations

A repository developed by Duke University engineers that they call a "materials genome" could allow scientists to stop using trail-and-error methods for combining electricity-producing materials. The thermoelectrics database project covers thousands of compounds, and provides detailed "recipes" for creating most efficient combinations for a particular purpose.

Scientists tackle the carbon conundrum

U.S. scientists have developed a new, integrated, ten-year science plan to better understand the details of Earth's carbon cycle and people's role in it. Understanding the carbon cycle is central for mitigating climate change and developing a sustainable future.

JEOL to launch world's smallest solid-state NMR probe
JEOL to launch world's smallest solid-state NMR probe

According to JEOL Resonance, a new benchmark for resolution and benchmark will be set with its introduction next week of a new 0.75-mm solid state nuclear magnetic resonance (NMR) probe. The probe is capable of high resolution sample analysis by spinning the sample at 110 kHz, the world's fastest spinning speed for NMR.

Energy Harvesting Subsystems for Wireless Sensors

Nextreme Thermal Solutions has developed two new energy harvesting subsystems for the plumbing and HVAC industries. The subsystems are the latest additions to Nextreme's Thermobility energy harvesting platform that uses thin-film thermoelectric technology to convert available thermal energy into electric power for a variety of autonomous self-powered applications.
