Azobenzene molecular glasses with tuned glass transition temperatures : from optimal light‐induced motion to self‐erasable gratings
(Royal Society of Chemistry, 2020-04-01)
The rate of photomechanical formation of surface relief gratings (SRG) in thin films of azobenzene materials depends on their glass transition temperature (Tg), with an optimal Tg around 50–60 °C yielding the fastest SRG ...
Highly active, entirely biobased antimicrobial Pickering emulsions
(Wiley, 2021-03-18)
We present the development of surfactant‐free, silica‐free and fully biobased oil‐in‐water antimicrobial Pickering emulsions, based on the self‐assembly of b ‐cyclodextrin and phytoantimicrobial oils (terpinen‐4‐ol or ...
Molecular-level photo-orientation insights into macroscopic photo-induced motion in azobenzene-containing polymer complexes
(American Chemical Society, 2021-07-13)
As part of continuing efforts to deepen the understanding of photo-induced mass transport in azo-containing polymers, we compared the diffraction efficiency (DE) during surface-relief grating (SRG) inscription, photo-induced ...
On the importance of noncrystalline phases in semicrystalline electrospun nanofibers
(American Chemical Society, 2021-11-18)
Tailoring the properties of electrospun fibers requires a detailed understanding and control of their microstructure. We investigate the structure/property relationships in fabrics of randomly aligned fibers of polylactide, ...
Glass engineering of aminotriazine-based materials with sub-ambient Tg and high kinetic stability
(Royal Society of Chemistry, 2020-06-08)
A challenge in glass engineering is the design of molecular glasses combining a high glass kinetic stability (GS) of the
amorphous phase with a low (sub‐ambient) glass transition temperature ...
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 ...
Thermal degradation of conventional and nanoencapsulated azoxystrobin due to processing in water, spiked strawberry and incurred strawberry models
(American Chemical Society, 2022-09-21)
Nanoencapsulated formulations of pesticides have been recently developed, and some products are now marketed for specific applications in agriculture. Pesticide residues present in raw agricultural products can degrade or ...
Field evaluation of the potential effects of polymer and silica-based nanopesticides on strawberries and agricultural soils
(Royal Society of Chemistry, 2022-08-18)
Polymeric and SiO2 nanoparticles can be used as nanocarriers to improve the efficacy of pesticide delivery in agriculture. However, the environmental fate and potential risks of this type of nanopesticides in agroecosystems ...
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 ...
