Eleven Thousand Interference Fringes by 1-MV Field Emission Electron Microscope

Three-Dimensional Apoptotic Nuclear Behavior Analyzed by Means of Field Emission in Lens Scanning Electron Microscope

Apoptosis is an essential biological function required during embryogenesis, tissue homeostasis, organ development and immune system regulation. It is an active cell death pathway involved in a variety of pathological conditions. During this process cytoskeletal proteins appear damaged and undergo an enzymatic disassembling, leading to formation of apoptotic features. This study was designed to...

Color Blindness in Eleven Thousand Museum Visitors *

The world of color presents no more surprising phenomenon than that of color-blindness which is ever playing a mysterious backstage role in human experience. An example of its more serious pranks is the following historic incident. Maximilian Hell of Vienna was the one astronomer to observe the transit of Venus in 1769 from the most favorable station on the globe, a position at the northern ext...

New Method for Multiple Immunodetection on Resin Ultrathin Section in the Field Emission Scanning Electron Microscope

Localization of a specific protein within the cell ultrastructure in high resolution is based on a specific bond between the molecule of interest (antigen) and an antibody conjugated to an electron dense nanoparticle clearly visible in consecutive observation in the electron microscope. Colloidal gold nanoparticles are usually used as the label. Diameter of the nanoparticle must be small enough...

Fabrication and characterization of solid-state nanopores using a field emission scanning electron microscope

Surface Characterization and Field Emission Measurements of Copper Samples inside a Scanning Electron Microscope

Vacuum breakdown in normal-conducting accelerating structures is a limiting factor for high gradient acceleration. Many aspects of the physics governing the breakdown process and its onset are yet to be fully understood. At Uppsala University we address these questions with an in-situ experimental setup mounted in an environmental scanning electron microscope. It consists of a piezo motor drive...
