World’s most powerful microscope ready for research

June 18, 2013 1:26 pm | News | Comments

The world’s most powerful microscope, which resides in a specially constructed room at the Univ. of Victoria, has now been fully assembled and tested, and has a lineup of scientists and businesses eager to use it. The seven-ton, 4.5-m-tall scanning transmission electron holography microscope, the first such microscope of its type, came to the university in parts last year.

Atomic-scale investigations solve key puzzle of LED efficiency

May 22, 2013 7:58 am | News | Comments

From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. Their full potential, however, remains untapped. A contentious controversy surrounds the high intensity of indium gallium nitride, with experts split on whether or not indium-rich clusters within the material provide the LED's remarkable efficiency.

Physicists discover a new kind of friction

May 15, 2013 11:26 am | News | Comments

In a quest to develop low-friction components for ever smaller mechanical systems, a team of physicists in Germany has recently discovered a previously unknown type of friction that they call “desorption stick.” The researchers examined how and why single polymer molecules in various solvents slide over or stick to certain surfaces. They found that an unexpected factor was responsible for the friction they observed.

The mechanism that puts the curl in the curling stone revealed

May 13, 2013 3:10 pm | News | Comments

In the curling sport, the players shoot their stones along the ice so that they slowly slide towards the target area, almost 30 m away. The game has its name from the slightly curved "curled" path taken by the stone, when released with a slow rotation. Researchers from Uppsala University in Sweden can now reveal the mechanism behind this curving path.

Team observes real-time charging of a lithium-air battery

May 13, 2013 9:07 am | by David L. Chandler, MIT News Office | News | Comments

One of the most promising new kinds of battery to power electric cars is called a lithium-air battery. But progress has been slow. Researchers have used transmission electron microscope (TEM) imaging to observe, at a molecular level, what goes on during a reaction called oxygen evolution as lithium-air batteries charge; this reaction is thought to be a bottleneck limiting further improvements to these batteries.

Imaging nanoscale polarization in ferroelectrics with coherent X-rays

May 7, 2013 11:19 am | News | Comments

An international team working to image ferroelectric thin films have reported the development of a new X-ray imaging technique, coherent X-ray Bragg projection ptychography. Under certain conditions, these thin films, which are used in computer memory, form networks of nanoscale domains with distinct local polarizations that are normally difficult to image.

New imaging technique visualizes bio-metals and molecules simultaneously

May 2, 2013 2:25 pm | by Juliette Savin, RIKEN | News | Comments

Metal elements and molecules interact in the body, but visualizing them together has always been a challenge. Researchers at RIKEN in Japan have developed a new molecular imaging technology that enables them to image bio-metals and bio-molecules at the same time in a live mouse. This new technology will enable researchers to study the complex interactions between metal elements and molecules in living organisms.

Scientists make world’s smallest stop-motion film

May 2, 2013 9:22 am | News | Comments

Even without certification by Guinness World Records, it would be easy to believe a short, 250-frame film recently created by an IBM Research team is the world’s smallest. Named “A Boy and His Atom,” the movie was created by precisely placing thousands of atoms using a scanning tunneling microscope. This type of atomic-level control is the result of years of efforts by IBM to determine the lower limits for storing data.

Scientists at Virginia Tech have invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment.

Team Effort

April 24, 2013 2:16 pm | by Paul Livingstone | Articles | Comments

Advances in microscopy and fundamental science are closely intertwined. Without prior understanding of the basis for research, the tools of microscopy are useless. Without microscopy, an understanding of how materials, chemistry, or life behave(s) at the molecular and atomic level cannot be discovered.

Using an ultra-bright electron source, scientists at the University of Toronto have recorded atomic motions in real time, offering a glimpse into the very essence of chemistry and biology at the atomic level. Their recording is a direct observation of a transition state in which atoms undergo chemical transformation into new structures with new properties.

Researchers find out why some stress is good for you

April 17, 2013 7:19 am | by Robert Sanders, UC Berkeley | News | Comments

Much research has demonstrated that chronic stress elevates levels of glucocorticoid stress hormones, which impairs memory. And stress is associated with a lot of other physical ailments. But less is known about the effects of acute stress, and studies have been conflicting. Recent work shows that intense, short-lived stress causes the proliferation of new neurons, improving mental performance.
