Improving Calibration of Atomic Force Microscopes

Spotting molecule-sized features-common in computer circuits and nanoscale devices-may become both easier and more accurate with a sensor developed at the National Institute of Standards and Technology (NIST). With their new design, NIST scientists may have found a way to sidestep some of the problems in calibrating atomic force microscopes (AFMs).

Conversion of TiO2 Nanotubes into BaTiO3

Due to their excellent electro-mechanical energy conversion capability also at the nanoscale, BaTiO3 nanostructure arrays are gaining a great interest for energy harvesting applications. The systematic study on the hydrothermal conversion of TiO2 nanotubes obtained by anodic oxidation allowed the fabrication of rod-like nanostructured BaTiO3 arrays with promising ferroelectric properties. Their compositional homogeneity, crystalline phase and size, of importance for their application, are discussed. more

Nano-Movies of Biomolecules: Using X-Ray Laser as Ultra Slow-Motion Camera

An international team, including scientists from DESY, has caught a light sensitive biomolecule at work with an X-ray laser. The study proves that X-ray lasers can capture the fast dynamics of biomolecules in ultra slow-motion, as the scientists led by Prof. Marius Schmidt from the University of Wisconsin-Milwaukee write in the journal Science. "Our study paves the way for movies from the nano world with atomic spatial resolution and ultrafast temporal resolution", says Schmidt.

Correlative Microscopy of Optical Materials

Modern optical and optoelectronic devices are composed of different optical materials and photonic structures which need to be analyzed at the microscale. Comprehensive micro-characterization including functional and structural properties mostly requires a combination of different microscopic techniques applied to these devices. In this article the characterization of optical materials with Correlative Light and Electron Microscopy (CLEM) is outlined for the example of a Light Emitting Diode (LED).

A Breakthrough in Electron Microscopy

Imagine that you want to find out from a single picture taken of the front of a house, what the building looks like from behind, whether it has any extensions or if the brickwork is damaged, and how many rooms are in the basement. Sounds impossible? Not in the nanoworld. Scientists from Jülich and Xi'an have developed a new method with which crystal structures can be reconstructed with atomic precision in all three dimensions. Admittedly, they did not use a picture from a simple digital camera to perform this feat, but rather an image from an ultra-high resolution electron microscope. The process is also especially suitable for the spatial mapping of radiation-sensitive samples, which would be quickly destroyed by the high energy measurement beam. The results have been published in the current edition of Nature Materials.
