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. moreSep. 21, 2012

Low-powered Nanotweezers May Benefit Cellular-level Studies

Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power "optical nanotweezers" can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples.

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. moreNov. 01, 2005

Gold Nanoparticles Under the Microscope

Gold Nanoparticles Under the Microscope. Patterned structures and surfaces are ubiquitous in nature: from the hide of a giraffe to the distribution of galaxies in the universe, similar repeating structural elements are seen on all length scales. These somewhat ordered structures can often be said to arise by a process of self-assembly or self-organisation. more
