Transport properties reduction

One commonly found feature is a reduction in process times, simply because flow conditions allow a faster sequence of all necessary processing steps such as mixing and completion of reaction and promote reaction by optimized transport properties. 

In the early 1970s, Spear and coworkers (Spear, 1974 Le Comber et al., 1974), although unaware of the presence of hydrogen, demonstrated a substantial reduction in the density of gap states (with a corresponding improvement in the electronic transport properties) in amorphous silicon films that were deposited from the decomposition of silane (SiH4) in an rf glow discharge. 

The kinetics of AgGl dissolution in aqueous solutions without supporting electrolyte have been studied utilizing well-defined and high mass transport properties of the scanning electrochemical microscope [376]. An ultramicroelectrode probe positioned close to the AgGl surface was used to induce and monitor dissolution of the salt via reduction of Ag+ from the initially saturated solution. 

Many ferromagnets are metals or metallic alloys with delocalized bands and require specialized models that explain the spontaneous magnetization below Tc or the paramagnetic susceptibility for T > Tc. The Stoner-Wohlfarth model,6 for example, explains these observed magnetic parameters of d metals as by a formation of excess spin density as a function of energy reduction due to electron spin correlation and dependent on the density of states at the Fermi level. However, a unified model that combines explanations for both electron spin correlations and electron transport properties as predicted by band theory is still lacking today. 

The transport properties of a near-critical system contain an enhancement or a reduction due to critical fluctuations in addition to the contributions of molecular transport processes which are strictly a function of the thermodynamic state. Therefore, the transport coefficients in the critical region are usually... 

A reduction in reaction time by virtue of the improved transport properties in eledroosmotic-driven microreadors was demonstrated for the P-dipeptide synthesis using pentafluorophenyl O-activation. Fmoc-P-alanine was preactivated by introducing the pentafluorophenyl fundion as ester group [9]. Dmab-P-alanine and the pentafluorophenyl ester of Fmoc-P-alanine readed, and the synthesis of the corres-... 

Mondal et al. investigated the influence of functionalized MWNTs on microstructure and water vapor transport properties of SPU membranes (95). The presence of MWNT was expected to decrease the permeability due to the more tortuous path for the diffusing molecules that must bypass through impermeable nanoparticles. Experimental results revealed that there were about 20% reductions... 

In Eqs. (6) and (7), the parameter a, which reflects the viscosity reduction at the solute surface from the bulk, is introduced as a variable to examine the correlations between transport properties of different modes We employ two functions for the position dependent viscosity, instead of one, in order to show that the validity of our results does not depend on the particular choice of the functional form...
