A legend has been prevailing whereby these Thorium (Old FD) lenses were sharper side-to-side and at all apertures than the subsequent New FD version. Believers claim this to be due to the properties of Thorium dioxide glass with its enhanced refractive indices. However, direct comparisons have revealed that advances in optical design and lens ...
The EA288 engine family is based on the EA189 engine family. [1] EA288 diesel shares displacement, bore pitch, stroke and bore ratio with the EA189 and the new EA211 gasoline engines. [2]
Thorium dioxide (ThO 2), also called thorium (IV) oxide, is a crystalline solid, often white or yellow in colour. Also known as thoria, it is mainly a by-product of lanthanide and uranium production. [4] Thorianite is the name of the mineralogical form of thorium dioxide. It is moderately rare and crystallizes in an isometric system.
Thorium(IV) fluoride (Th F 4) is an inorganic chemical compound. It is a white hygroscopic powder which can be produced by reacting thorium with fluorine gas. At temperatures above 500 °C, it reacts with atmospheric moisture to produce ThOF 2 .
Thorium was also used in certain glass elements of Aero-Ektar lenses made by Kodak during World War II. Thus they are mildly radioactive. [16] Two of the glass elements in the f/2.5 Aero-Ektar lenses are 11% and 13% thorium by weight. The thorium-containing glasses were used because they have a high refractive index with a low dispersion ...
Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. The term can also refer to a chip conforming to the standard ISO/IEC 11889. Common uses are to verify platform integrity (to verify that the boot process starts ...
