The adsorptions of polyethylene glycol monomethyl ether (PEGMME) and dimethyl (PEGDME) on CaA, NaX, NaY, ZSM-5 zeolites have been analyzed by using experimental FT-IR Raman spectroscopies. vibration wavenumbers polymers adsorbed reported the adsorption properties with different molecular sizes cations compared. Disappearing some modes or shifts to higher lower frequency region after zeolites; i...

Sorption is often carried out in stirred batch reactors without any consideration of how much mixing sufficient to avoid the effect diffusion compromising yield and cost due overmixing. Therefore, focus this work was study maximum sorption capacity, removal efficiency, kinetics power consumption (P) studied process are affected by different speeds, i.e., impeller speed/minimum speed for complet...

The boundary conditions of intraparticle diffusion in nanoporous materials may be chosen to approach the limiting cases of either absorbing or reflecting boundaries, depending on the host-guest system under study and the temperature of measurement. Pulsed field gradient nuclear magnetic resonance is applied to monitor molecular diffusion of n-hexane and of an n-hexane-tetrafluoromethane mixture...

MnPO neurons play a critical role in hydromineral homeostasis regulation by acting as sensors of extracellular sodium concentration ([Na(+)]out). The mechanism underlying Na(+)-sensing involves Na(+)-flow through the NaX channel, directly regulated by the Na(+)/K(+)-ATPase α1-isoform which controls Na(+)-influx by modulating channel permeability. Together, these two partners form a complex invo...

A n effective adsorbent for the ethylene/ethane separation has been prepared by the dispersion of CuCl in large NaX crystals. The results from the thermo gravimetric analysis (TGA) indicate a maximal dispersion capacity of 36 wt% of CuCl for the NaX crystals. Single component isotherms of ethane and ethylene on CuCl/NaX show that the CuCl containing adsorbents are highly favourable to the olefi...
