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 ...
Smart packaging in the sustainability challenge : eumelanin as a UV-absorption enhancer of polymers
(Institute of Electrical and Electronics Engineers, 2019-09-19)
The black-brown biopigment eumelanin screens the harmful ultraviolet (UV) radiation in the human skin. In industry, the absorption of plastics in the UV range is improved by the inclusion of additives. Our work reports an ...
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 ...
