Taming macromolecules with light : lessons learned from vibrational spectroscopy
(Wiley, 2017-09-12)
Exciting new applications, from large-area nanopatterning and templating to soft light-powered robotics, are emerging from the fundamental research on light-triggered changes in macromolecular systems upon photoisomeriza-tion ...
Influence of supramolecular interaction type on photoresponsive azopolymer complexes : a surface relief grating formation study
(American Chemical Society, 2016-06-24)
The influence of the supramolecular interaction type—hydrogen bonding, proton transfer, and pure ionic bonding—on photoresponsive behavior, particularly surface relief grating (SRG) inscription, has been investigated using ...
Orientation and partial disentanglement in individual electrospun fibers : diameter dependence and correlation with mechanical properties
(American Chemical Society, 2015-06-29)
Electrospun fibers are versatile materials that exhibit unusual and tunable properties when studied at the single fiber level, including an exponential increase in modulus with a decreasing diameter toward the nanoscale. ...
Bridging the gap between the mesoscopic 2D order–order transition and molecular-level reorganization in dot-patterned block copolymer monolayers
(American Chemical Society, 2016-11-21)
Langmuir–Blodgett (LB) films of amphiphilic block copolymers (BCs) form well-defined nanostructures with long-range order useful, for instance, for nanolithography applications. Nanostructures with a 2D circular micelle ...
Raman spectroscopy of individual poly(ethylene oxide) electrospun fibers : effect of the collector on molecular orientation
(Elsevier, 2016-09-06)
Electrospun fibers are complex polymeric materials with a typical diameter of a few
hundred nanometers that are often frozen in out-of-equilibrium states due to the fast solvent
evaporation and high elongational forces ...
Selective isotopic labeling resolves the gel-to-fluid phase transitions of the individual leaflets of a planar-supported phospholipid bilayer
(American Chemical Society, 2019-07-05)
Knowledge of the thermotropic phase behavior of solid-supported bilayer lipid assemblies is essential to mimick the molecular organization and lateral fluidity of cell membranes. The gel-to-fluid phase transitions in a ...
Covalently crosslinked mussel byssus protein-based materials with tunable properties
(Wiley, 2018-03-01)
Mussels’ anchoring threads, named byssus, are collagen-rich fibers with outstanding mechanical properties. Our previous work has shown the possibility of producing a byssus protein hydrolyzate with good film-forming ability, ...
Glass versus crystal : a balancing act between competing intermolecular interactions
(American Chemical Society, 2017-04-14)
Hydrogen (H) bonds can be used either for crystal engineering or for designing compounds capable of forming very stable glassy phases. Herein, a second type of directional noncovalent interaction, π–π stacking, is introduced ...
Photoactive/passive molecular glass blends : an efficient strategy to optimize azomaterials for surface relief grating inscription
(American Chemical Society, 2016-12-15)
: Irradiation of azomaterials causes various photophysical and photomechanical effects that can be exploited
for the preparation of functional materials such as surface relief gratings (SRGs). Herein, we develop and apply ...
Photocontrol of supramolecular azo-containing block copolymer thin films during dip-coating : toward nanoscale patterned coatings
(American Chemical Society, 2019-05-07)
Dip-coating allows nanostructured block copolymer (BCP) thin film fabrication in a fast and facile one-step process. It can also be coupled with external controls, such as illumination. Herein, we expose several design ...
