The adverb sic, meaning 'intentionally so written', first appeared in English c. 1856. [4] It is derived from the Latin adverb sīc, which means 'so', 'thus', 'in this manner'. [5] According to the Oxford English Dictionary, the verbal form of sic, meaning 'to mark with a sic', emerged in 1889, E. Belfort Bax 's work in The Ethics of Socialism ...
Alexandra Elbakyan at a conference at Harvard (2010). Sci-Hub was created by Alexandra Elbakyan, who was born in Kazakhstan in 1988. [22] Elbakyan earned her undergraduate degree at Kazakh National Technical University [23] studying information technology, then worked for a year for a computer security firm in Moscow, then joined a research team at the University of Freiburg in Germany in 2010 ...
The polymorphs of SiC include various amorphous phases observed in thin films and fibers, [3] as well as a large family of similar crystalline structures called polytypes. They are variations of the same chemical compound that are identical in two dimensions and differ in the third. Thus, they can be viewed as layers stacked in a certain sequence.
The only wide bandgap materials in group IV are diamond and silicon carbide (SiC).. There are many III–V and II–VI compound semiconductors with wide bandgaps. In the III-V semiconductor family, aluminium nitride (AlN) is used to fabricate ultraviolet LEDs with wavelengths down to 200–250 nm, gallium nitride (GaN) is used to make blue LEDs and laser diodes, and boron nitride (BN) is ...
This is a list of semiconductor fabrication plants.A semiconductor fabrication plant is where integrated circuits (ICs), also known as microchips, are manufactured.They are either operated by Integrated Device Manufacturers (IDMs) that design and manufacture ICs in-house and may also manufacture designs from design-only (fabless firms), or by pure play foundries that manufacture designs from ...
SiC–SiC matrix composite is a particular type of ceramic matrix composite (CMC) which have been accumulating interest mainly as high temperature materials for use in applications such as gas turbines, as an alternative to metallic alloys. CMCs are generally a system of materials that are made up of ceramic fibers or particles that lie in a ...
Silicon carbide (SiC), also known as carborundum (/ ˌkɑːrbəˈrʌndəm /), is a hard chemical compound containing silicon and carbon. A wide bandgap semiconductor, it occurs in nature as the extremely rare mineral moissanite, but has been mass-produced as a powder and crystal since 1893 for use as an abrasive.
For her actions in creating Sci-Hub, Elbakyan has been called a hero, [42] [43] for example by Nobel laureate Randy Schekman. [44] Ars Technica has compared her to Aaron Swartz, [45] and The New York Times has compared her to Edward Snowden. [31] Edward Snowden acknowledged Sci-Hub to be one of the most important websites for academics in the ...
