To find the radius of one molecule of oxygen given the van der Waals constant, we can follow these steps: Step 1: Calculate the volume of one mole of oxygen According to the problem, the van der Waals constantbis equal to four times the volume of one mole of oxygen. Therefore, we can...
The van der Waals equation of state around the van Laar point The discovery of van Laar that the van der Waals equation of state for binary mixtures can be solved analytically at the double point on the critical line,... Meijer,HE Paul - 《Journal of Chemical Physics》...
We derive exact analytical solutions to the Schrödinger equation featuring a dual-scale potential, namely, a blend of a van der Waals (vdW) potential and an isotropic harmonic potential. The asymptotic behaviors of these solutions asr→0andr→∞are also elucidated. These results are obtained thr...
Van der Waals forces, hydrogen bonding, and sterics cannot account for such a large range for comparably sized molecules. It has been suggested66 that the ORs are, in large fraction, metalloproteins, and that metal ion (Cu+, Zn2 +, etc.) ligation of strong Lewis base analytes (e.g.,...
In order to develop an efficient and accurate quasi-continuum approach for contact problems of low-dimensional nanoscale carbon materials, a van der Waals contact-bond model is proposed in this study. This method can involve the important information of nano- and micro-structures, such as the ...
whereC_6is the dispersion coefficient and\mu =m_im_k/(m_i+m_k)the reduced mass of a given pair. Notice that there is a different definition in the literature6for this length,l_{\mathrm{vdW}}=0.5R. In previous research of four-body systems22, we showed that the van der Waals len...
