Nacre, also known as the mother of pearl, has an intricate, highly regular structure that makes it an incredibly […]

ANIMATION Oak Ridge National Laboratory’s Center for Nanophase Materials Sciences, or CNMS, contributed to a groundbreaking experiment published in Science that tracks the real-time transport of individual molecules. A team led by the University of Graz, Austria, used unique four-probe scanning tunneling microscopy, or STM, to move a single molecule between two […]

Researchers at the University of Tokyo have found a way to enhance the sensitivity of existing quantitative phase imaging so that all structures inside living cells can be seen simultaneously, from tiny particles to large structures. This artistic representation of the technique shows pulses of sculpted light (green, top) traveling […]

The thin and cost-effective lens is 3D printed and has the capacity to put live cells under the microscope, which would significantly improve diagnostics.

Credit: MIPT While 100-nanometer thin films of vanadium dioxide (VO2) do not normally conduct electricity, their resistance drops up to 100,000 times when slightly heated. This may happen under applied voltage, for example. That property is used to create high-speed switchable devices and sensors for direct current or alternating signal in […]

Artist’s view of individual electrons interacting with an optical whispering gallery mode as it circles a silica sphere. The matching between the velocities of the electron and the light-wave it is riding changes the quantum state of the electron, illustrated as a wider halo. Credit: Dr. Murat Sivis Research team […]
