Pneumonoultramicroscopicsilicovolcanoconiosis is the longest word in the English language. The word can be analysed as follows: Pneumono: from ancient Greek (πνεύμων, pneúmōn) which means lungs; ultra: from Latin, meaning beyond; micro and scopic: from ancient Greek, meaning small looking, referring to the fineness of ...
Miner's phthisis, Grinder's asthma, Potter's rot, [1] pneumonoultramicroscopicsilicovolcanoconiosis [2] [3] Slice of a lung affected by silicosis: Specialty: Pulmonology: Types: Chronic silicosis: includes two types itself, simple silicosis and progressive massive fibrosis, Accelerated silicosis, Acute silicosis: Differential diagnosis
[5] [2] Ultramicrobacteria possess a relatively high surface-area-to-volume ratio due to their small size, which aids in growth under oligotrophic (i.e. nutrient-poor) conditions. [2] The relatively small size of ultramicrobacteria also enables parasitism of larger organisms; [ 2 ] some ultramicrobacteria have been observed to be obligate or ...
In 1902, the ultramicroscope was developed by Richard Adolf Zsigmondy (1865–1929) and Henry Siedentopf (1872–1940), working for Carl Zeiss AG. [1] Applying bright sunlight for illumination they were able to determine the size of 4 nm small nanoparticles in cranberry glass.
Ultrastructure (or ultra-structure) is the architecture of cells and biomaterials that is visible at higher magnifications than found on a standard optical light microscope. This traditionally meant the resolution and magnification range of a conventional transmission electron microscope (TEM) when viewing biological specimens such as cells ...

Background Chlorine and caustic soda are produced at chlor-alkali plants using mercury cells or the increasingly popular membrane technology that is mercury free and more energy-
The typical value of 500–700 nm can be improved to 100–150 nm, which corresponds to an almost spherical focal spot with 5–7 times less volume than that of standard confocal microscopy. The improvement in resolution is achieved by using two opposing objective lenses, both of which are focused to the same geometric location.
