“Nanojuice” could improve how doctors examine the gut

July 7, 2014 8:05 am | by Cory Nealon, Univ. at Buffalo | News | Comments

Located deep in the human gut, the small intestine is not easy to examine: X-rays, MRIs and ultrasound images each suffer limitations. Univ. at Buffalo researchers are developing a new imaging technique involving nanoparticles suspended in liquid to form “nanojuice” that patients would drink. Upon reaching the small intestine, doctors would strike the nanoparticles with laser light, providing a non-invasive, real-time view of the organ.

Japanese gold leaf artists worked on the nanoscale

July 2, 2014 3:10 pm | News | Comments

Ancient Japanese gold leaf artists were truly masters of their craft. An analysis of six of these Japanese paper screens show that these artifacts are gilded with gold leaf that was hand-beaten to the nanometer scale. The study was able to prove this without any damage to the screens through the use of x-ray fluorescence spectroscopy.

Nature of solids and liquids explored through new pitch drop experiment

July 2, 2014 12:47 pm | News | Comments

Known as the “world's longest experiment”, an experiment at the University of Queensland in Australia was famous for taking ten years for a drop of pitch, a black, sticky material, to fall from a funnel. A new test in the U.K. is using a different bitumen, or pitch, which is 30 times less viscous than the Queensland experiment, so that the flow can be seen at a faster rate and hopefully provide more insights.

Scientists develop force sensor from carbon nanotubes

June 30, 2014 2:05 pm | News | Comments

A group of researchers from Russia, Belarus and Spain, including MIPT professor Yury Lozovik, have developed a microscopic force sensor based on carbon nanotubes. The device consists of two nanotubes placed so that their open ends are opposite to each other. Voltage of just 10 nA is then applied to the nanocircuit and force is measured by the change in position of the nanotubes.

“Compressive sensing” provides new approach to measuring a quantum system

June 27, 2014 3:14 pm | News | Comments

In quantum physics, momentum and position are an example of conjugate variables, connected by Heisenberg’s Uncertainty Principle, which says that both quantities cannot be simultaneously measured precisely. Univ. of Rochester physicists have recently shown that a technique called compressive sensing that offers a way to measure both variables at the same time without violating the Uncertainty Principle.

Diamond plates create nanostructures through pressure, not chemistry

June 27, 2014 3:09 pm | News | Comments

You wouldn’t think that mechanical force could process nanoparticles more subtly than the most advanced chemistry. But researchers at Sandia National Laboratories have created a newly patented and original method that uses simple pressure to produce finer and cleaner results in forming silver nanostructures than do chemical methods, which are not only inflexible in their results but leave harmful byproducts.

Study: Squashed extinct volcanoes cause tsunamis

June 27, 2014 9:58 am | News | Comments

Tsunami earthquakes happen at relatively shallow depths in the ocean and are small in terms of their magnitude. However, they create very large tsunamis: just 5.6 on the Richter scale can produce a 10-m wave. New research reveals that tsunami earthquakes may be caused by extinct undersea volcanoes causing a “sticking point” between two sections of the Earth’s crust called tectonic plates, where one plate slides under another.
