The lateral interaction for molecular orientation rearrangement of adsorbates was investigated using high-resolution electron-energy-loss spectroscopy (HREELS). The adsorption configuration of CO on Pd(110) was identified, based on the observation of hindered rotational vibrations in the dipole-scattering spectra. With increasing coverage, the CO orientation switches from the upright configurat...

The influence of molecular configuration on the filtration of macromolecules across glomerular capillary walls was examined by comparing fractional clearances of two uncharged polysaccharides of distinctly different molecular configuration in the Munich-Wistar rat. The macromolecules employed were dextran, a slightly branched polymer of glucopyranose, and ficoll, a highly cross-linked copolymer...

Quantum-dot cellular automata (QCA) is an approach to computing that eliminates the need for current switches by representing binary information as the configuration of charge among quantum dots. For molecular QCA, redox sites of molecules serve as the quantum dots. The Coulomb interaction between neighboring molecules provides device–device coupling. By introducing clocked control of the QCA c...
