Ted Pella Introduces Pelco Graphene TEM Support Films

Ted Pella, Inc has announced the availability of the new research-ready Pelco graphene TEM support films.
The films are supported by lacey carbon film on a 300 mesh copper grid. The single, continuous graphene sheet covers the entire 300 mesh area of the TEM grid. This creates a usable area of around 75% of the TEM grid, leaving plenty of space for specimens or experiments. The Pelco graphene TEM support films with the large area continuous film can be used directly out of the box. moreApr. 29, 2013

Transmission Electron Microscopy: Imaging Nanoparticles in Action

The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects. In a recently published study, scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first time, the imaging of nanoscale processes, such as the engulfment of nanoparticles into cells.

Single Electron Events in TEM

Single Electron Events (SEE) have been used to quantify the point spread function of several cameras for Transmission Electron Microscopy (TEM). The spatial resolution is measured by the Single Electron Modulation Transfer Function (MTFSEE) compared with the MTF generated by standard knife edge experiment. In addition, the sensitivity of the camera as a function of high tension has been measured, showing an excellent Signal-to-Noise Ratio (SNR) from 300 kV down to 8 kV.

Interdisciplinary Nanoscience Center Uses AFM Force Spectroscopy to Work at the Interface Between ...

The group of Dr Rikke Meyer from the interdisciplinary Nanoscience Center (iNANO) at Aarhus University, Denmark has used AFM and single-cell force spectroscopy to work at the interface between microbiology and nanoscience in the quest to understand how bacteria form biofilms and how this may be prevented. moreOct. 18, 2012

Nanomanipulator for in-situ Liftout TEM Sample Preparation

The EasyLift nanomanipulator from FEI allows improved ease of use, reliability, precision and integration in preparing ultra-thin samples for analysis in a transmission electron microscope (TEM).

It is designed specifically for in-situ liftout TEM sample preparation and other demanding nanomanipulation activities. EasyLift is now available on the Helios NanoLab and Versa 3D DualBeam systems. moreSep. 27, 2012

Imaging Dynamic Processes at the Atomic Scale

FEI Company has introduced an environmental transmission electron microscope (ETEM) that enables time-resolved, in-situ studies of processes and materials exposed to reactive gases and elevated temperatures.
Titan ETEM G2 can be used to study the relationships between structure and performance by observing atomic scale processes and gas-solid interactions under conditions that mimic the operational environment. The system is designed for in situ chemical reactions and catalysis experiments. moreMar. 07, 2012

Sub-nanometre Resolution Imaging with Ptychographic Electron Microscopy

Researchers at the University of Sheffield have revolutionised the electron microscope by developing a new method which could create the highest resolution images ever seen.

For over 70 years, transmission electron microscopy (TEM), which `looks through´ an object to see atomic features within it, has been constrained by the relatively poor lenses which are used to form the image.
