Title: Water adsorption on aggregates of spherical aerosol nano particles
Author: Nie, Chu
Abstract: A three dimensional integral equation is developed in order to compute water adsorption onto aggregates of spherical aerosol nano particles . The integral equation is derived from molecular density functional theory , with a weighted density approximation and a direct correlation function interpolation rule . Only required inputs are the direct correlation functions of the uniform fluid or gas at both high -density and low -density limits . The equation has been tested on argon adsorption onto a graphite planer substrate ; the result corresponds well with previous simulation work . Adsorption of both noble gas and water onto a single spherical nano particle and aggregates of spherical nano particles has been computed with the developed equation . For the adsorption of a single spherical substrate , layer structure has been found , the adsorption shows a transition property when substrate size increases and when the substrate size is over 100 ? ? the adsorption is nearly the same as that of a planer substrate . For adsorption of aggregates of spherical nano particles , not only much strong adsorption appears but also adsorption property changes with different configurations of spherical nano particles .
