Efficient molecular recognition based on nonspecific van der Waals interaction at the solid/liquid interface.
نویسندگان
چکیده
A highly efficient recognition phenomenon was observed between alkoxylated arylene-ethynylene macrocycles bearing identical side chains but different core size, which is based on van der Waals interactions between alkoxy chains. The ratio of both molecules and the environment of each molecule have been statistically analyzed to quantify the recognition efficiency.

Highly Sensitive Detection of H2S Molecules Using a TiO2-Supported Au Overlayer Based Nanosensors: A Van Der Waals Corrected DFT Study
The adsorption of the H2S molecule on the undoped and N-doped TiO2 anatase supported Au nanoparticles were studied using density functional theory calculations. The adsorption of H2S on both Au and TiO2 sides of the nanoparticle was examined. On the TiO2 side, the fivefold coordinated titanium site was found to be the most favorable binding site, giving rise to the strong interaction of H2S wit...
متن کاملVLE Predictions of Strongly Non-Ideal Binary Mixtures by Modifying Van Der Waals and Orbey-Sandler Mixing Rules
By proposing a predictive method with no adjustable parameter and by using infinite dilution activity coefficients of components in binary mixtures obtained from UNIFAC model, the binary interaction parameters (k12) in van der Waals mixing rule (vdWMR) and Orbey-Sandler mixing rule (OSMR) have been evaluated. The predicted binary interaction parameters are used in Peng-Robinson-S...
متن کاملModifications of Internal Molecular Structures of Asphalt Components Due to Physical Aging
The internal structure of a molecule can be presented in terms of intra-molecular (i.e., inter atomic)and inter-molecular energies such as van der Waals, bond and bending, torsion, and inversion energy.In this study, changes in molecular energies of individual asphalt components are evaluated as afunction of physical aging factors. The factors for physical aging such as temperature and pressure...
متن کاملDetermination of the Second Virial Coefficient for Binary Mixtures of Ar with CH4 and CO using Van der Waals and Dieterici Models
In this paper, we calculate the second virial coefficient for binary mixtures of Ar with CH4 and CO in order to evaluate the performance of equations of state (EOSs). The investigated EOSs are van der Waals (vdW), Redlich-Kwong (RK), Peng-Robinson (PR), Carnahan-Starling–van der Waals (CS-vdW) and Guggenheim-van der Waals (G-vdW) based on van der Waals model. In our work, we also use Dieterici ...
