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. ...
Sample preparation for the analysis of nanoparticles in natural waters by single particle ICP-MS
(Elsevier, 2021-11-12)
With the significant increase in the production and use of nanoparticles (NP), concern is increasing over their release into their environment. Single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) is ...
Probing interfacial interactions and dynamics of polymers enclosed in boron nitride nanotubes
(Wiley, 2021-11-23)
Understanding interfacial interactions in polymer systems is crucial for their applicability for
instance in adhesives and coatings. Enclosing polymers in a cylindrical volume provides a
system for studying interactions ...
Mixtures of rare earth elements show antagonistic interactions in Chlamydomonas reinhardtii
(Elsevier, 2021-06-14)
In order to better understand the environmental risks of the rare earth elements (REEs), it is necessary to
determine their fate and biological effects under environmentally relevant conditions (e.g. at low concentrations,
REE ...
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 ...
Effect of hydrogen-bond strength on photoresponsive properties of polymer-azobenzene complexes
(NRC Research Press & Canadian Society for Chemistry, 2020-04-16)
Supramolecular complexation between photoresponsive azobenzene chromophores and a photopassive polymer host offers synthetic and design advantages compared with conventional covalent azo-containing polymers. In this context, ...
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 ...
