Cannula transfer or cannulation is a set of air-free techniques used with a Schlenk line, in transferring liquid or solution samples between reaction...

constituents of air such as carbon monoxide (CO), carbon dioxide (CO2), and nitrogen (N2) are also possible. A variety of air-free techniques have been developed...

pressure than the surrounding air, so that any microscopic leaks are mostly leaking inert gas out of the box instead of letting air in. At the now-deactivated...

In the following text any "connection" is assumed to be rendered mostly air free through a series of vac-refill cycles. The standard Schlenk flask is a...

highly reactive toward water and protic compounds. It is handled using air-free technique. It is produced by the reaction of tri(sec-butyl)borane with potassium...

the HALO technique, the parachutist opens the parachute at a low altitude after free-falling for a period of time, while in the HAHO technique, the parachutist...

air-free techniques. Tributylphosphine is prepared industrially by the hydrophosphination of phosphine with 1-butene: the addition proceeds by a free...

phosphorus(III). The handling of oxophilic compounds often requires air-free techniques. Complexes of oxophilic metals typically are prone to hydrolysis...

yield (typically >75%), is operationally simple and does not require air-free techniques or heating. It suffers, however, from the very high toxicity and...

reacts with oxygen, the compound must be handled and stored using air-free techniques. Cobaltocene is prepared by the reaction of sodium cyclopentadienide...

The Reid technique is a method of interrogation after investigation and behavior analysis. The system was developed in the United States by John E. Reid...

solutions in solvents such as diethyl ether or tetrahydrofuran using air-free techniques. Grignard reagents are complex with the magnesium atom bonded to...

semiconductors. It is a colorless pyrophoric liquid, typically handled with air-free techniques. It was discovered by Cornell University chemists L. M. Dennis and...

the bench scale, chemists perform experiments on air-sensitive compounds using air-free techniques developed to handle them under inert gas. Helium,...

It is a red solid that is pyrophoric in the air, and thus is typically handled with air-free techniques. It was originally synthesized by Fred Tebbe...

combusted upon contact with air. Due to their pyrophoric nature, organozinc compounds are generally prepared using air-free techniques. They are unstable toward...

reagents and/or products, and the need for anhydrous reagents and air-free techniques. Thus his discovery gained much attention because of its simplicity...

proponents of this technique when taking free-kicks. Curling can be an effective technique when taking corners. The ball gradually moves in the air towards the...

hydrolyze and oxidize readily, Wittig reagents are prepared using air-free techniques. They are typically generated and used in situ. THF is a typical...

A narrative technique (also, in fiction, a fictional device) is any of several storytelling methods the creator of a story uses, thus effectively relaying...
