Moreover, the encapsulation of these substances inside the silica pores can increase their thermal and chemical stability. The incorporation of MEA, DEA and/or MDEA in mesoporous materials may provide an interesting and new alternative to CO2 capture, as demonstrated in this work. The pore size,...
Unlike the soda process, the MEA process (one of the best organic solvents for lignin) does not destroy carbohydrates, which leads to pulping with a higher yield than other conventional chemical processes. While there have been attempts to cook different lignocellulosic materials, i.e., wheat ...
InN thin films were grown by a new technique, migration enhanced afterglow (MEAglow), a chemical vapour deposition (CVD) form of migration enhanced epitaxy (MEE). Here we describe the apparatus used for this form of film deposition, which includes a scalable hollow cathode nitrogen plasma ...
The MEA is subject to physical and chemical damage during operation, leading to performance degradation and early failure. Overcoming these challenges requires a focus on MEA design and durability. The transition region of the MEA, which is exposed to physical damage and chemical contamination, plays...
Interpreting the spectrum from Raman spectroscopy requires the development of a calibration model specific to the chemical species of interest. The development of such a model requires data in the form of Raman spectra with the respective species concentration determined. The commonly applied method for...
Carbon paper is brittle, and carbon cloth is difficult to form, while the metal mesh is easy to form, and titanium material has excellent physical and chemical stability. Finally, diamond-shaped titanium mesh is used as an MEA substrate. PtRu/XC-72R (Produced by Johnson Matthey, London, UK...
Rotary pill press is the preferred product in pharmaceutical, chemical, electronics, food and other enterprises in production, rotary tablet press machine pill press machine is also suitable for pressing that material that is difficult formed into tablet, meet the requi...

As shown in Table IV, the molecular parameters are not yet satisfactory from the stereo- chemical point of view, because the reasonable structure refinement could not be made enough well due to too small number of observed reflections (184) compared with the total number of adjustable parameters...
The main objective of the current work was to investigate the flue gas degradation of monoethanolamine (MEA) in the process with special emphasis on the NO_x induced chemical reactions. Degradation experiments have been carried out at absorber like conditions in the AmiNO_x rig, followed by ...
