The requirements for anodic bonding are clean and even wafer surfaces and atomic contact between the bonding substrates through a sufficiently powerful electrostatic field. Also necessary is the use of borosilicate glass containing a high concentration of alkali ions.
TSP is still sold and used as a cleaning agent, but since the late 1960s, its use has diminished in the United States and many other parts of the world because, like many phosphate-based cleaners, it is known to cause extensive eutrophication of lakes and rivers once it enters a water system.
Sampling a rock hyrax midden from the Gifberg Pass, Western Cape, South Africa. A rock hyrax midden is a stratified accumulation of fecal pellets and a brown amber-like a urinary product known as hyraceum excreted by the rock hyrax and closely related species.
Hyraxes are well-furred, rotund animals with short tails. [3] Modern hyraxes are typically between 30 and 70 cm (12 and 28 in) in length and weigh between 2 and 5 kg (4 and 11 lb). They are superficially similar to marmots, or over-large pikas, but are much more closely related to elephants and sirenians. Hyraxes have a life span from nine to ...
The words "rabbit", "hare", or "coney" appear as terms for the hyrax in some English translations of the Bible. Early English translators had no knowledge of the hyrax (Hebrew שָּׁפָן shaphan[9]), and therefore no name for them. Not only in English but also in the Greek and the Latin translation they are talking about rabbits and hares.
The first self-cleaning glass was based on a thin film titania coating. [3] The film can be applied by spin coating of organo-titanate chelated precursor (for example titanium iso-tetrapropoxide chelated by acetylacetone), followed by heat treatment at elevated temperatures to burn the organic residues and to form the anatase phase.
The rock hyrax (/ ˈ h aɪ. r æ k s /; Procavia capensis), also called dassie, Cape hyrax, rock rabbit, and (from some [3] interpretations of a word used in the King James Bible) coney, is a medium-sized terrestrial mammal native to Africa and the Middle East.
Procavia is a genus of hyraxes. The rock hyrax (P. capensis) is currently the only extant species belonging to this genus, though other species were recognized in the past, including P. habessinica and P. ruficeps, both now relegated to subspecific rank. Several fossil species are known as well, the oldest dated to the Early Pliocene, including:
