Photo-induced Force Microscopy Measures Nanoparticles With Light

A new technique called “photo-induced force microscopy,” which probes the optical properties of nanomaterials by measuring the physical force imparted by light, is being tested by scientists at Rice University. Isabell Thomann’s primary research centers on using nanoparticles and sunlight to reduce the carbon footprint of power plants. A major focus is photocatalysis, a class […]

Femtosecond Laser Pulse Control Of Electron Microscope Nanotips

A method of controlling electron emissions with higher precision than ever before has been developed by researchers at Vienna University of Technology, together with colleagues from the FAU Erlangen-Nürnberg in Germany. In an electron microscope, electrons are emitted by pointy metal tips, so they can be steered and controlled with high precision. Recently, such metal […]

Revolving Scanning Transmission Electron Microscopy eliminates Distortion

A new technique from microscopy researchers at North Carolina State University accounts for tiny movements and eliminates resulting distortion from the finished product. When capturing images at the atomic scale, using scanning transmission electron microscopes (TEMs), even the most miniscule movements of a sample can cause skewed or distorted images. Such movements are virtually impossible […]
