“Optical fingerprints” on an electron beam

Researchers observe non-linear optical processes in the electron microscope

17-Jan-2024 - The precise control of electron beams in so-called transmission electron microscopes (TEM) makes it possible to analyze materials or molecules at the atomic level. Combined with short light pulses, these devices can also be used to analyze dynamic processes. Researchers from Göttingen and ...

Crystal structures in super slow motion

Researchers first to succeed in filming a phase transition with extremely high spatial and temporal resolution

26-Jan-2021 - Laser beams can be used to change the properties of materials in an extremely precise way. This principle is already widely used in technologies such as rewritable DVDs. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they ...

New electron microscope method detects atomic-scale magnetism

27-Jun-2016 - Scientists can now detect magnetic behavior at the atomic level with a new electron microscopy technique developed by a team from the Department of Energy's Oak Ridge National Laboratory and Uppsala University, Sweden. The researchers took a counterintuitive approach by taking advantage of ...

Batteries as they are meant to be seen

03-Jan-2014 - Researchers have developed a way to microscopically view battery electrodes while they are bathed in wet electrolytes, mimicking realistic conditions inside actual batteries. While life sciences researchers regularly use transmission electron microscopy to study wet environments, this time ...

Defects make catalysts perfect

Insights into the process which converts carbon dioxide into methanol could make it possible to recycle greenhouse gas

02-May-2012 - There is now one less mystery in chemical production plants. For many decades industry has been producing methanol on a large scale from a mixture of carbon dioxide and carbon monoxide, as well as hydrogen. An international team, including chemists from the Fritz Haber Institute of the Max Planck ...

High-resolution atomic imaging of specimens in liquid by TEM using graphene liquid cell

Looking into specimens on an atomic level in liquids, and understanding atomic processes so far regarded impossible

11-Apr-2012 - The Korea Advanced Institute of Science and Technology (KAIST) announced that a research team from the Department of Materials Science and Engineering has developed a technology that enables scientists and engineers to observe processes occurring in liquid media on the smallest possible scale ...

Nanopower: Avoiding electrolyte failure in nanoscale lithum batteries

23-Mar-2012 - It turns out you can be too thin—especially if you're a nanoscale battery. Researchers from the National Institute of Standards and Technology (NIST), the University of Maryland, College Park, and Sandia National Laboratories built a series of nanowire batteries to demonstrate that the thickness ...

SALVE Project Enters Second Phase

Successful evaluation phase prompts University of Ulm and Carl Zeiss to continue with their joint venture to develop a high-performance transmission electron microscope

16-Aug-2011 - Following the successful completion of a two-year evaluation phase, the University of Ulm, the Heidelberg-based company CEOS GmbH and Carl Zeiss Nano Technology Systems have signed an agreement to embark on the next phase of the SALVE project. SALVE – which stands for Sub-Angstrom Low Voltage ...

Software for the discovery of new crystal structures

16-May-2011 - A new software called QED (Quantitative Electron Diffraction), which has been licensed by Max Planck Innovation, has now been released by HREM Research Inc., a Japan based company, which is developing products and services in the field of High-Resolution Electron Microscopy. QED allows ...
