Baburin, Holger Ott, Beatriz Gil-Hernández, Joaquín Sanchiz, Christoph Janiak: A rare alb-4,8-Cmce metal–coordination network based on tetrazolate and phosphonate functionalized 1,3,5,7-tetraphenyladamantane.
2016-3-28 · Mixtures of acetone with dimethyl sulfoxide or 1-methyl-2-pyrrolidone led to submicron particles with a spherical morphology. The main parameters that could affect the nano- or micro-precipitation were studied using mixtures of acetone and dimethyl sulfoxide rather than 1-methyl-2-pyrrolidone due to the low toxicity of DMSO.

2019-4-27 · It reacts with many volatile organic compounds and oxidizers to produce even more explosive gaseous mixtures. This gas is also very harmful and even lethal if swallowed or absorbed by the breathing tracts. Chronic exposure can lead to severe effects to vital organs and can impair fetus health in pregnant women.
B121R12 This unit allows the preparation of used SF 6 gas containing an inadmissibly high percentage of nitrogen or air to the desired quality so that the SF 6 can be reused in gas compartments.. The purifiion technology of the separating unit is based on the SF 6 condensation under pressure at low temperature principle. We recommend using this unit where large SF 6 quantities have to be

Purifiion and preparation of SF 6 gas mixtures SF 6 recycling and re-use. In practice, it often happens that the used SF 6 gas is contaminated with air by inadequate evacuation or improper gas handling. Used SF 6 gas containing an unacceptably high percentage of nitrogen and air can be prepared by separating units to the desired quality level. The advantages of gas preparation:
2019-3-28 · Efficient separation of CO2 from CO2/CH4 mixtures using meranes has economic, environmental and industrial importance. Merane technologies are currently dominated by polymers due to their processing abilities and low manufacturing costs. However, polymeric meranes suffer from either low gas permeabilities or low selectivities. Metal organic frameworks (MOFs) are suggested as …

The OPC-N2 measures particles from 0.38 micron to 17 micron diameter accurately, repeatedly, and with minimal maintenance using the patented pump-less design. A proven technology, the OPC-N2 provides both PM readings and real time particle size histograms, competing in performance with existing analytical units but at a fraction of the cost.
