متن کاملSelf-assembly of resins and asphaltenes facilitates asphaltene dissolution by an organic acid.
Asphaltene precipitation occurs in petroleum fluids under certain unfavorable conditions, but can be controlled by tuning composition. Aromatic solvents in large quantities can prevent precipitation entirely and can dissolve already precipitated asphaltenes. Some polymeric surfactants can dissolve asphaltenes when added at much lower concentrations than required by aromatic solvents. Other disp...
متن کاملPolysiloxane/Polystyrene Thermo-Responsive and Self-Healing Polymer Network via Lewis Acid-Lewis Base Pair Formation.
The use of thermo-reversible Lewis Pair (LP) interactions in the formation of transient polymer networks is still greatly underexplored. In this work, we describe the synthesis and characterization of polydimethylsiloxane/polystyrene (PDMS/PS) blends that form dynamic Lewis acid-Lewis base adducts resulting in reversible crosslinks. Linear PS containing 10 mol % of di-2-thienylboryl pendant gro...
متن کاملSurface-Confined Molecular Self-Assembly
The design and fabrication of nanometer-sized entities of defined structure on the nanometer scale is a challenge hardly achievable by large-scale top-down procedures. In particular, alternative techniques are needed to structure surfaces at very small length scales. In nanotechnology the process of self-assembly has become a potent method which allows to vanquish these difficulties. Self-assem...
متن کاملDesigning ordered nucleic acid self-assembly processes.
A major goal of self-assembly research is the synthesis of biomolecular structures with diverse, intricate features across multiple length scales. Designing self-assembly processes becomes more difficult as the number of species or target structure size increases. Just as the ordered assembly of a machine or device makes complex manufacturing possible, ordered (or 'algorithmic') biomolecular se...
