Metal–ligand interactions and salt bridges as sacrificial bonds in mussel byssus-derived materials
(American Chemical Society, 2016-09-02)
The byssus that anchors mussels to solid surfaces is a protein-based material combining strength and toughness as well as a self-healing ability. These exceptional mechanical properties are explained in part by the presence ...
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 ...
In situ photocontrol of block copolymer morphology during dip-coating of thin films
(American Chemical Society, 2015-09-28)
We demonstrate a unique combination of simultaneous top-down and bottom-up control of the morphology of block copolymer films by application of in situ optical irradiation during dip-coating. A light-addressable and ...
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. ...
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 ...
Polarized raman analysis of polymer chain orientation in ultrafine individual nanofibers with variable low crystallinity
(American Chemical Society, 2018-10-26)
Recent mechanical studies of ultrafine electrospun polymer nanofibers showed they can simultaneously possess high strength and toughness attributed to high degree of chain alignment coupled with low crystallinity. Quantitative ...
Triazine‐based molecular glasses frustrate the crystallization of barbiturates
(Royal Society of Chemistry, 2019-02-05)
Hydrogen bonding is a key element of supramolecular chemistry and is often used in crystal engineering to direct crystal packing. In particular, systems where motifs with multiple hydrogen (H) bonds are present, such as ...
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 ...
