“…For example, a leaf constitutes of cell lattice, and an imagined capillary can produce capillary pressure to selectively absorb gas or nanoparticles, as a result, selective oxidation or selective adsorption can be observed. This results are helpful to design a nanofiber membrane by either electrospinning or bubble electrospinning or macromolecular electrospinning [16][17][18][19][20][21][22][23].…”

Water pollution has become a major global problem and requires an immediate action. It was generally considered that pollutants were diffused gradually from surface to underwater region, where plants and animals should have less affected. However, diffusion of contamination is very slow in comparison with penetration. Here we show saline water has a highly selective penetration, and the penetration rate is much higher than that of diffusion. An experiment was carried out using a drop of red ink as a point pollution source to check both diffusion and penetration processes in various salt solutions with different concentrations, the salt concentration greatly affects the penetration process and there is a threshold value beyond which no penetration occurs. An imaged capillary is adopted in this paper to explain the selective penetration on a molecular scale, revealing that the salt concentration and temperature will greatly affect the capillary pressure and the penetration depth. Our results demonstrate that the penetration is the main pollution dispersion, and we anticipate our theory would shed light upon the major pollution problem from theoretical analysis to pollution control.

A magnetic and electric fields assisted electrospinning, in which a charged copper ring was placed between the needle and the two paralleled magnets receivers, was presented to produce aligned polyacrylonitrile/graphene/Fe 3 O 4 (PAN/Gr/Fe 3 O 4) magnetic composite nanofibers. Characterizations of the magnetic composite nanofibers were investigated by means of scanning electron microscopy, Fourier transform infrared spectroscopy, high-resistance meter, and other methods. The results showed that Gr and Fe 3 O 4 nanoparticles are suitable additives to improve alignment degree and conductive properties of nanofibers.

“…Most fractional equations are generated by solving specific problems of science and engineering, for example the gas permeability of a nanofiber membrane, [1][2][3][4][5][6] moisture permeability through a cocoon, 7,8 nanoscale multiphase flow, 9 solvent evaporation in the bubble electrospinning, [10][11][12] oscillators arising in microphysics and tsunami motion, 13,14 and sound transmission in hierarchic porous medium that can be exactly modeled by fractional calculus. [15][16][17] There are many fractional derivatives in literature, which are incompatible with each other, among which He's fractional derivative, 15 the local fractional derivative, [18][19][20] the Riemann-Liouville fractional derivative, the Caputo fractional derivative, the Hadamard fractional derivative, and the Atangana-Baleanu fractional derivative 21 are widely used.…”

Local fractional nonlinear oscillators are studied by a modification of the homotopy perturbation method coupled with the variational iteration method. In the solution process, the fractional variational iteration method is adopted to transform the nonlinear oscillator equation into an integral equation, which is then decomposed into a series of equations, which are solved by the homotopy perturbation method. Two examples are given to show that the proposed method is simpler and more flexible than the classical homotopy perturbation method. It is also shown that the key to use this method is to select the appropriate decomposition of the initial value series.
