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 ...
Near-infrared vibrational overtone spectra of teepleite, Na2B(OH)4Cl, and its deutero analog : research report
(2021-12-05)
Single crystals of the naturally occurring mineral teepleite, Na2B(OH)4Cl, and its deuterated
analog were grown and their polarized near-infrared absorption spectra recorded at 10 K. The
spectra show three intense, sharp ...
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 ...
Electronic absorption spectroscopy
(Elsevier, 2021)
Absorption spectroscopy in the ultraviolet, visible and near-infrared (UV-VIS-NIR) wavelength ranges is one of the oldest and most often used characterization methods in coordination chemistry. This overview illustrates ...
Time-dependent theory of electronic spectroscopy
(Elsevier, 2021)
The time-dependent theory of electronic spectroscopy provides an intuitive approach to understand and quantitatively analyze absorption, luminescence and resonance Raman spectra beyond vertical transition energies. The ...
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 ...
