Ultramicrotomy is a method for cutting specimens into extremely thin slices, called ultra-thin sections, that can be studied and documented at different magnifications in a transmission electron microscope (TEM). It is used mostly for biological specimens, but sections of plastics and soft metals can also be prepared.
A ribbon of ultrathin sections prepared by room-temperature ultramicrotomy, floating on water in the boat of a diamond knife used to cut the sections. The knife blade is the edge at the upper end of the trough of water. An ultramicrotome is a main tool of ultramicrotomy. It allows the preparation of extremely thin sections, with the device ...
The Navy "E" Ribbon was designed by AZ3 Cynthia L. Crider in 1973. Her design and recommendation were approved by the Secretary of the Navy after three years, and the ribbon was subsequently created by the Department of the Army, which has the final approval for the design and colors of all ribbons and medals in the U.S. military.
The ribbon bar is 35 millimetres (1.4 in) wide with a 2.4 mm stripe of scarlet at the edges. A 0.8mm stripe of white separates, a 0.8mm stripe of Old Glory Blue from a 4.0mm stripe of white. Next a 6.3mm stripe of Old Glory Blue is separated by a 1.6mm stripe of white from the 1.6mm center stripe of Golden Yellow. [4]
His research interests included: physics of self assembly and function of artificial and biological membranes, viscoelastic microscopy of cells, physics of the actin based cytoskeleton: micro-rheology of macromolecular networks, applications of solid-supported lipid-protein membranes, ultrathin hydrated polymer layers and polymer/membrane ...
Rodney S. "Rod" Ruoff is an American physical chemist and nanoscience researcher. He is one of the world experts on carbon materials including carbon nanostructures such as fullerenes, nanotubes, graphene, diamond, and has had pioneering discoveries on such materials and others.
Humberto Fernández-Morán Villalobos (18 February 1924 – 17 March 1999) [1] was a Venezuelan research scientist born in Maracaibo, Venezuela, known for inventing the diamond knife or scalpel, significantly advancing the development of electromagnetic lenses for electron microscopy based on superconducting technology, and many other scientific contributions.
Pier Giorgio Righetti (born 25 April 1941, Forlì, Northern Italy) [1] is a professor emeritus of chemistry. He worked primarily at the University of Milano (1971-1995) and at the Department of Chemistry of the Politecnico di Milano in Milan, Italy (2005-2011).
