Solid-State NMR Views of Chitin and Chitosan in Fungal Pathogens

high-resolution information on the structure of chitin and chitosan in their cellular contexts

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

Time-Temperature Scaling Observed by Neutron Spectroscopy on Bottlebrush PolymersQuasi-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 

thermal-diffusion frontal polymerization in TMPTA with metal strips

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.
