theoretical chemistryFaster calculations: Simulations, which yield the polymer equation of state (e.o.s.), are carried out by applying an external field to the polymers. The figure shows e.o.s. isotherms calculated using this method (lines) compared to those obtained in earlier simulations (...
(9) in dimensionless form with the help of dimensionless space and time variables {η, τ}, as (105)∂C∂τ+Pe(u−1−215β*)∂C∂η/Pe=1Pe2∂2C∂(η/Pe)2+∂2C∂y2. The longitudinal diffusion term (first term of R.H.S. of the above equation), whose effect...
9). And this trend is confirmed by the simple 2D Poission-Nernst-Planck equation [63]. Although several investigations of complex 3D/3D, 3D/2D, 3D/1D heterogeneous structured nanochannels are emerging, single 1D nanochannels are still the basic systems of ionic diodes. As shown in the Fig. ...
Then, we can set the denominator (d) on the right side of the equation as 1. By calculating this proportion, we will get the concentration – mass of the substance per 1 unit of volume. Knowing the concentration of fluids is very useful in everyday life, and one such application of ...
Temperature dependence of the degradation rate constants, described by the Arrhenius equation, was higher at atmospheric pressure than at elevated pressures, ... L Verbeyst,I Oey,IVD Plancken,... - 《Food Chemistry》 被引量: 135发表: 2010年 Pressure and temperature dependence of the unimolecular...
(PRAM) module11,33in ADCHAM by incorporating NO3chemistry and refining the representation of alkoxy radical (RO) isomerization, which better describes HOM formation through the interactions between monoterpenes and NOx. As shown in Fig.1and Supplementary Fig.2, the model not only reproduces the ...
A 1-compartment toxicokinetic model is used to characterize the chemical exposure toxicity space (CETS), providing a novel graphic tool that can aid in the design of aquatic toxicity tests for fish and for interpreting their results. The graph depicts the solution to the differential equation descr...
Additionally, for each Aβ42 concentration, the contribution of the aggregates to the FCS curves (factor 1-R in Supplementary Equation S2) is constant over the incubation time (Fig. 1e), indicating that the proportion of aggregates present in each sample is also independent of the time ...
In deforming porous media, the volumetric flux of the solid phase can be expressed in terms of the velocity, according to the following equation: (9.34)us=εsvs where εs and vs denote the solid phase volume fraction and velocity, respectively. Substituting Eq. (9.19), Eq. (9.34) becomes...
The Scherrer equation (Eq. (1)) was employed to calculate the crystallite size of anatase (1 0 1) [60] for TiO2, TiO2/rGO (1 wt%) and TiO2/rGO (5 wt%) samples.(1)ParticleSize=0.9×λ/Lcosθ Where λ is 0.154 nm, L is the full width at half maximum (FWHM) intensity of th...
