Research Highlights
Solid-State NMR Views of Chitin and Chitosan in Fungal Pathogens
Solid-state NMR data were analyzed using principal component analysis and heatmap
comparison to investigate the atomic-level structure of chitin and chitosan structures
in the alive cells of six types of fungal pathogens.
Universality of Time-Temperature Scaling Observed by Neutron Spectroscopy on Bottlebrush Polymers
Quasi-elastic neutron scattering detects dynamical processes in the time range of
pico to nano seconds in combination with spatial resolution by means of momentum transfers,
Q, allowing to track fast vibrations, methyl group rotations and segmental dynamics.
We have studied PDMS-g-PDMS in the Q -range of Q ≥ Å-1 and separated the processes
based on their temperature scaling. This enabled the combination of all processes
across the glass transition temperature resulting in the full proton mean square displacement
of the bottlebrush polymers.
Frontal Polymerization
In this article, we perform a combined experimental, numerical, and analytical investigation
of the thermal-diffusion-promoted frontal polymerization (FP) in trimethylolpropane
triacrylate (TMPTA) with embedded metal strips. The study reveals that the enhancement
in the front velocity is mainly due to a preheating effect associated with the conductive
element. Moreover, the numerical parametric study for the system size shows that the
front speed increases as the system size decreases, ultimately approaching a prediction
provided by a homogenized model for polymer–metal composites.
