Jul 16, 2009Zn(NH3)2. Ammonia is a Lewis base because it has a lone pair, and the zinc is a Lewis acid because it is positively-charged. The lone pair is donated to the metal cation and a coordination compound is formed. Because zinc is +2, it can accomodate two ammonia ligands.

Apr 30, 2020That's the equivalent of removing 100 million cars from the road and more than all other clean energy sources combined. It also keeps the air clean by removing thousands of tons of harmful air pollutants each year that contribute to acid rain, smog, lung cancer and cardiovascular disease. 2. Nuclear energy's land footprint is small

Detectors and sensors The new MIRA analyzer, developed by Aeris Technologies Inc., represents a disruptive advance in the laser-based gas analysis space, achieving "gold standard" ppb-level performance comparable to systems that are 10 to 15× larger and heavier.

Single-tube nested (STN) real-time RT-PCR assays overcome these limitations by manipulating annealing temperatures, thereby enabling reverse transcription, external primer amplification and internal primer amplification to take place sequentially in the same tube [ 12 ].

Feb 14, 2011Thus, a fast loop is often used (Figure 3). A fast loop is an external loop with minimal sample conditioning that is cycled to a close proximity to the analyzer and from which the actual sample to the analyzer is taken. A common way to separate the secondary (slow) loop from the primary or fast loop is to flow the sample through a bypass filter.
