A comparison of the noncovalent complexation of tetraethyl and tetraphenyl resorcinarenes with mono-, di-, and oligosaccharides revealed that both the relative abundance and stability of the complexes increase up to biose and triose, but start to decrease after that point, as the length of the oligosACcharide is increased.

- 4 May 2005
Ab initio methods were used to investigate the nanoscale friction between two graphite layers placed in contact and most of the calculated friction coefficients fell within the range of values of 0.07-0.14.
Ab initio studies on nanoscale friction between fluorinated diamond surfaces: effect of model size and level of theory.

- 27 July 2006
Interactions between two fluorinated diamond surfaces placed in contact with each other were investigated with quantum chemical Hartree-Fock and Møller-Plesset perturbation theory and basis sets def-SV(P), def-TZVP, and 6-31G to examine how model size and level of theory affect the atomic-scale friction.
