However, a consistent and satisfying definition of self-sustainability is still missing. Currently...
(0.16–0.85mm radius in a tube of radius 5.6mm, at a velocity from 5 to 90cm s−1and viscosity from 17 to 410 cP. Ploehn assumed that lateral migration of small particles is primarily due to diffusion, while large particles are focused by the inertial force at an equilibrium position,...
where dehydration of boronic acids leads to the formation of boroxines [150]. The equilibrium between boroxines and boronic acids can be modified by adjusting factors such as temperature, the introduction of a Lewis base, or altering the concentration ...
The wave function of interest, in terms of which all the previous discussion of calculations has taken place, is the electronic wave function for the molecule at its equilibrium nuclear geometry. The equilibrium geometry is supposed to be that nuclear geometry which minimises the sum of the ...
Global Equilibrium calculations.Why design a kinetic scheme when all you have to do is give Kintecus a listing of all the relevant species in your system.No need for ANY REACTIONS!In fact, you do not even have to specify which species are reactions or products! You can even perform phase ...
Given the different model equilibrium constraints, in general, the adsorption species dominance was (1) SO2UO2 (pH 5.2–5.6), (2) SO2UO2CO32− (pH 8.3–8.5), (3) SO2UO2CO3HCO33− (pH 7.5–8.7), (4) SO2UO2HCO31− (pH 6.5–7.8), ...
Although water is recognized as a desirable solvent for catalysis and as a promising raw material for solar generation of fuels such as H_2 and CH_3OH (from CO_2 and water), relatively few kinetics and equilibrium studies of hydricity in aqueous media have been reported. 原...
Increasing the temperature to 900 K promotes larger perturbations of the equilibrium geometry of the 13P skeleton, resulting in more dramatic changes in the electron delocalization at the top and bottom of the cage, as monitored by theδ(OH,OH) andδ(NH2,NH2) metrics (Supplementary Fig.20)...
If the fish's food consists of a single type of prey that is at equilibrium with the water, the fish's aqueous and dietary exposures and the bioconcentration factor (BCF) can be calculated when they are equal: (4.1)AE=DE; QCw=FwCp;BCF=QFw The ventilation-to-feeding ratio for a 1 kg...
(Fig.6A). Other studies have investigated producing H2from BFG by using a CO2sorbent to effectively shift the reaction equilibrium towards H2production via the water–gas shift reaction. Although this process has been demonstrated on pilot scale [43], its product is a mixed H2/N2stream that ...
