[12] In metallurgy, precipitation from a solid solution is also a way to strengthen alloys. Precipitation of ceramic phases in metallic alloys such as zirconium hydrides in zircaloy cladding of nuclear fuel pins can also render metallic alloys brittle and lead to their mechanical failure.
1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) is a chemical compound with the formula C 7 H 12 N 2. [1] It is an amidine base used in organic synthesis. A related compound with related functions is 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The relatively complex nature of the formal names for DBU and DBN (hence the common use of acronyms) reflects the ...
Pure ammonium formate decomposes into formamide and water when heated, and this is its primary use in industry. Formic acid can also be obtained by reacting ammonium formate with a dilute acid, and since ammonium formate is also produced from formic acid, it can serve as a way of storing formic acid.
This is an imperfect analogy with chemistry, since a chemical molecule may sometimes have only one atom, as in monatomic gases.) [49] The definition that "nothing else is a formula", given above as Definition 3 , excludes any formula from the language which is not specifically required by the other definitions in the syntax.

[12] Studies in task switching and response selection show that there are differences through the two types of processing. Top-down processing primarily focuses on the attention side, such as task repetition. [13] Bottom-up processing focuses on item-based learning, such as finding the same object over and over again.
