Fabricating inexpensive, high-temp SQUIDs for future electronic devices

24-Jun-2015

High-transition-temperature superconductivity within copper-oxide materials was discovered in 1986, and quickly set into motion an intense research effort by scientists and engineers around the globe to develop superconducting electronics capable of operating at and above liquid nitrogen ...

Measuring the mass of molecules on the nano-scale

By observing the shift in eigenstates of coupled microcantilevers, researchers can measure nanogram-scale mass in a liquid environment with extreme accuracy

04-Jun-2015

Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error - potentially ...

New technique speeds nanoMRI imaging

Multiplexing technique for nanoscale magnetic resonance imaging cuts normal scan time from two weeks to two days

01-Jun-2015

NanoMRI is a scanning technique that produces nondestructive, high-resolution 3-D images of nanoscale objects, and it promises to become a powerful tool for researchers and companies exploring the shape and function of biological materials such as viruses and cells in much the same way as ...

New technique for exploring structural dynamics of nanoworld

30-Apr-2015

A new technique for visualizing the rapidly changing electronic structures of atomic-scale materials as they twist, tumble and traipse across the nanoworld is taking shape at the California Institute of Technology. There, researchers have for the first time successfully combined two existing ...

Optical nanoantennas set the stage for a NEMS lab-on-a-chip revolution

26-Feb-2015

Newly developed tiny antennas, likened to spotlights on the nanoscale, offer the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer, according to the Australian scientists who created them. The new antennas are cubic in shape. They do a ...

Mechanism of dengue virus entry into cells

19-Feb-2014

Dengue fever, an infectious tropical disease caused by a mosquito-borne virus, afflicts millions of people each year, causing fever, headache, muscle and joint pains and a characteristic skin rash. In some people the disease progresses to a severe, often fatal, form known as dengue hemorrhagic ...

Designing an acoustic diode

Novel design for a device that would transmit sound in 1-way may lead to brighter, clearer ultrasound images and improve diagnosis and therapy

05-Nov-2013

Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new technology called an "acoustic diode," envisioned by researchers in China's Nanjing University, may dramatically improve future ultrasound ...

Measuring blood sugar with light

29-Oct-2013

One of the keys to healthful living with Type 1 and Type 2 diabetes is monitoring blood glucose (sugar) levels to ensure they remain at stable levels. People can easily and reliably do this at home using electronic devices that read sugar levels in a tiny drop of blood. Now a team of German ...

A new approach to detecting food contamination enables real-time testing of food and processing plant equipment

22-Oct-2013

As anyone who has ever consumed bacteria-contaminated food and experienced "food poisoning" can tell you, it's a miserable experience. Yet it's an all-too-common one, with foodborne illnesses making 1 in 6 Americans -- or 48 million people -- sick each year. Of these people sickened, 128,000 end ...

Computer model predicts red blood cell flow

15-Aug-2013

Adjacent to the walls of our arterioles, capillaries, and venules -- the blood vessels that make up our microcirculation -- there exists a peculiar thin layer of clear plasma, devoid of red blood cells. Although it is just a few millionths of a meter thick, that layer is vital. It controls, for ...
