माइक्रोटॉम इसके अंग्रेजी अर्थ का उदाहरण

The company also produced photographic lenses (1883), spectacle lenses (1889), microtomes (1890), binoculars and telescopes (1893).

Humberto Fernández Morán (1924–1999) contributed to the development of the electron microscope and was the first researcher to introduce the concept of cryoultramicrotomy.

Programming language theory 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).

Ultramicrotomy process.

Ultra-thin sections of specimens are cut using a specialized instrument called an "ultramicrotome".

The ultramicrotome is fitted with either a diamond knife, for most biological ultra-thin sectioning, or a glass knife, often used for initial cuts.

There are numerous other pieces of equipment involved in the ultramicrotomy process.

Tissue sections obtained by ultramicrotomy are compressed by the cutting force of the knife.

Finally, thin sections are cut with a glass or diamond knife using an ultramicrotome and the sections are left floating on water that is held in a boat or trough.

In 1952 Humberto Fernandez Morán introduced cryo ultramicrotomy, which is a similar technique but done at freezing temperatures between −20 and −150°C.

Cryo ultramicrotomy can be used to cut ultra-thin frozen biological specimens.

One of the advantages over the more "traditional" ultramicrotomy process is speed, since it should be possible to freeze and section a specimen in 1 to 2 hours.

His innovative contribution was making a modified version of thin-sectioning microtome, by which he could make histological sections of only 100–150 Å in thickness.

Cytoarchitectonics is one of the ways to parse the brain, by obtaining sections of the brain using a microtome and staining them with chemical agents which reveal where different neurons are located.
