The synthesis and characterization of a novel heterogeneous anion exchange membrane with the aim of improving performance and increasing its nitrate selectivity was investigated.
In the absence of hydrogen, the conversion of halon 1211 over Al2O3 and Pd/Al2O3 gives a similar product profile and the reactions follow a heterogeneous halogen exchange reaction pathway, which takes place on the positively charged aluminum ions.
In the presence of Ag+ ions in the solution a thin Ag2S film of ca. 30 300 nm thickness is formed on the CdS surface due to the heterogeneous cation exchange reaction CdS + 2Ag+ = Ag2S + Cd2+.
In order to improve recovery of tritium from blankets over a wide range of temperature, the effect of catalytically active metal additives on the heterogeneous isotope exchange reactions at the breeder/sweep gas interface was examined, and main results are summarized in this paper.
The higher electrical activity and therefore greater currents for the exfoliated Q2D WO3 nanoflakes appeared to be more related to higher heterogeneous electron exchange rate caused by the quantum confinement effects within the few-layers limit [47].
We expected that these patients would display heterogeneous gas exchange patterns during exercise, which cannot be explained by resting measurements alone.
Thin films of different metal alkoxides (M OR)n, where M is Si, Ti or Zr, and R is (CH2)nCH3) were used as interfacial layers (ILs), which were sandwiched between heterogeneous anion-exchange layers (AELs) and homogeneous cation-exchange layers (CELs) of sulfonated poly (ether sulfone) (SPS).
Electrochemical properties of heterogeneous anion-exchange membranes can be indicators of their fouling during electrodialysis of phenylalanine solutions.
Further, the pure d-[U-14C]-glucose obtained was converted to methyl-α-d-glucopyranoside ([U-14C]-glucose) by glycosidation with methanol using (i) HCl, the conventional Fischer method (ii) heterogeneous organic cation exchange resin (Amberlite IR-120 (H+)) and (iii) heterogeneous inorganic cation exchanged montmorillonites called metal M+n-monts.
Service-oriented architecture is an architectural style that steers all aspects of creating and using services throughout their lifecycle, as well as defining and providing the infrastructure that allows heterogeneous applications to exchange data.
