MAX phases, a unique class of layered ternary compounds, along with their two-dimensional derivatives, MXenes, have drawn considerable attention in many fields. Notably, their one-dimensional (1D) counterpart exhibits more distinct properties and enhance
Rewrite to the general form shown in formula Eq. (10). (10)x˙=F(x,Vm,τ) With the longitudinal inflow velocity as the bifurcation parameter, (x,Vm)=(0,Vm0) is the bifurcation point of the deterministic system, and Vm0 is the critical bifurcation point. Let Vm=Vm0+μ+uT, μ ...
ber of formula units per simulation cell, the number of generations (the number of CALYPSO steps), and the population size (the number of configurations in each step) were set to be 4, 40, and 30, respectively. Among the structures obtained by the PSO method, the 2D planar structure ...
The Green-Kubo formula has played a crucial role in understanding nonequilibrium transport processes though so far only qualitatively, as the exact values of a system's transport coefficients cannot be worked out explicitly given the system's Hamiltonian. A quantitative description of transport ...
MXenes have the typical formula Mn+1XnTx (n = 1, 2, 3), where M stands for an early transition metal such as Sc, Ti, V, Zr, Nb, Cr, or Mo; X is carbon or nitrogen; and Tx represents a surface functional group (such as –O, –OH, –F, etc.) [76,77]. They are ...
The MUSCL-Hancock solver reconstructs the solution within each cell using the MUSCL scheme, and the interface values obtained are evolved half the time step using Hancock’s formula. The numerical flux is determined using an approximate solution of the Riemann problem resorting the HLL (Harten-Lax...
height differences can be taken into account by the barometric height formula. The local air temperature can strongly vary along an optical path in the field, depending on shadowing, cloud coverage and ground material, for example. In practice, the key to low uncertainty in length measurement in...
We present a wind-tunnel simulation of adiabatic atmospheric flow normal to a rough, two-dimensional ridge. The data are analyzed in physical streamline coordinates, which are described in some detail. The mean velocity speed-up on the hill top is adequately predicted by existing formulae while ...
the commercial Pt/C and RuO2were coated on the CC with the loading of 3 mg for comparison.All values were calculated relative to the reversible hydrogen electrode(RHE)based on the formula E(RHE)=EHg/HgO+0.098+0.059pH.In addition,all polarization curves were corrected for removing the 90%iR...
MXenes23,24,25,26,27,28, i.e., a recently discovered family of two-dimensional (2D) early transition metal carbides, nitrides, or carbonitrides with a formula of Mn + 1XnTx (n = 1, 2, 3, X is C and/or N, and Tx are surface oxo, hydroxy, and/or fluoro groups) ca...
