Research news on Electron techniques

Electron techniques encompass a set of experimental methods that exploit the wave–particle duality and charge of electrons to probe, image, or modify matter at microscopic to atomic scales. Key modalities include electron microscopy (e.g., TEM, SEM, STEM), electron diffraction, and various electron spectroscopy techniques (such as AES and EELS), which rely on controlled electron beams and their interactions with atomic potentials, electronic structure, and surface topography. These techniques provide high spatial and energy resolution, enabling quantitative characterization of crystallography, composition, electronic states, and defects in materials, and are fundamental in condensed matter physics, materials science, nanotechnology, and surface science.

Newly discovered mechanism protects DNA during cell division

Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as DNA bridges that connect ...

AI-designed proteins help scientists see inside living cells

Cells are like metropolises, home to millions of molecular residents. If one were to stand atop a high-rise, trying to identify most of its inhabitants would seem an impossible task. Even with the sophisticated imaging tools ...

Peering into materials down to the nanoscale in the COCOON lab

A new Tufts University imaging facility is doing something that most microscopy centers in the world cannot: allowing scientists to examine a butterfly wing, a living tissue or a microchip and reveal its physical structure, ...
