The present study elucidates the factors that govern the spontaneous self-assembly of a family of dimetal [Pt(2)L(4)] (L=dithiocarboxylato ligand) complexes. Experimental data show that variables such as temperature, concentration, solvent and the nature of the ligand L have a critical effect on the reversible self-assembly of supramolecular [Pt(2)L(4)](n) entities. In solution, new UV/Vis spec...

A chemo-mechanical method was used to prepare cellulose nanofibrils dispersed uniformly in an organic solvent. Poly(ethylene glycol) (PEG 1000) was added to the matrix as a compatibilizer to improve the interfacial interaction between the hydrophobic poly(lactic acid) (PLA) and the hydrophilic cellulose nanofibrils. The composites obtained by solvent casting methods from N,N-Dimethylacetamide (...

A recently reported intermolecular potential for SF6, featuring exchange, dispersion, and electrostatic terms, is used to determine minimum energy structures of homogeneous SF6 clusters up to the decamer. By adding appropriate interaction terms, also structures of mixed (SF6)2-Arn clusters are calculated. A second order line shift formalism, treating the anharmonic intramolecular force field an...

In this paper, the snap-through buckling of an initially curved microbeam subject to an electrostatic force, accounting for fringing field effect, is investigated. The general governing equations of the curved microbeam are developed using Euler-Bernoulli beam theory and used to develop a new criterion for the snap-through buckling of that beam. The size effect of the microbeam is accounted for...

To examine the effects of weak intermolecular interactions on solid-phase extraction (SPE) and chromatographic separation, we synthesized some novel stationary phases with a heavy atom effect layer by immobilizing halogenated aromatic rings and hydroxyl groups onto the surface of a hydrophilic base polymer. Using SPE cartridges packed with the functionalized materials, we found that the heavy a...

Since the invention of scanning tunneling microscopy (STM), 2D supramolecular architectures have been observed under various experimental conditions. The construction of these architectures arises from the balance between interactions at the medium-solid interface. This review summarizes molecular motion observed in 2D-supramolecular structures on surfaces using nanospace resolution STM. The ob...

Mid-infrared photodissociation spectra of H2O-Arn (n ) 1-14) complexes have been recorded in the vicinity of the OsH stretch vibrations of the water cation. The rovibrational structure of the transitions in the dimer spectrum (n ) 1) are consistent with a planar, proton (H)-bound HsOsHsAr equilibrium geometry. The slightly translinear intermolecular bond in the ground vibrational state is chara...

The competition between intermolecular interactions and long-range lateral variations in the substrate-adsorbate interaction was studied by scanning tunnelling microscopy (STM) and force field based calculations, by comparing the phase formation of (sub-) monolayers of the organic molecules (i) 2-phenyl-4,6-bis(6-(pyridin-3-yl)-4-(pyridin-3-yl)pyridin-2-yl)pyrimidine (3,3'-BTP) and (ii) 3,4,9,1...

BACKGROUND Triptolide is a major active constituent isolated from Tripterygiumwilfordii Hook F, a Chinese herbal medicine. This study investigated the intermolecular interaction between triptolide and bovine serum albumin (BSA). MATERIALS AND METHODS The fluorescence, circular dichroism (CD) and molecular docking methods were used to investigate the intermolecular interaction between triptoli...
