The CuOFP capsule used as overpack for spent nuclear fuel disposal in the KBS-3 concept (Swedish version). Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below.
For the tertiary alcohols, the general form is RR'R"COH. The simplest example is tert -butanol (2-methylpropan-2-ol), for which each of R, R', and R" is CH 3 . In these shorthands, R, R', and R" represent substituents , alkyl or other attached, generally organic groups.
Strong bases are leveling solvents for acids, weak bases are differentiating solvents for acids. In a leveling solvent, many acids are completely dissociated and are thus of the same strength. All acids tend to become indistinguishable in strength when dissolved in strongly basic solvents owing to the greater affinity of strong bases for protons.
Monolith Inc. (formerly Boxer Industries) is an American chemical and materials producer based in Nebraska. The company is known for being the first company to use methane pyrolysis to split natural gas into carbon and hydrogen gas on a commercial scale.
HASL or HAL (for hot air (solder) leveling) is a type of finish used on printed circuit boards (PCBs). The PCB is typically dipped into a bath of molten solder so that all exposed copper surfaces are covered by solder. Excess solder is removed by passing the PCB between hot air knives.
Power level may refer to: Level (logarithmic quantity), logarithm of the ratio of the value of some quantity to a reference value of the same quantity.

"50 Divisions" is the most widely used standard for organizing specifications and other written information for commercial and institutional building projects in the United States and Canada. [5] Standardizing the presentation of such information improves communication among all parties.
The penetrator is a pointed mass of high-density material designed to retain its shape and carry the maximum possible amount of energy as deeply as possible into the target. The entire projectile is not normally made of the same material as the penetrator because the hard metals of good penetrators would damage the barrel of the gun firing the ...
