Summary: The study investigates the thermo-mechanical response of multi-layered polymeric struts at different temperatures using moderate rotations theory, discussing the relationship between material properties and geometry, as well as analyzing the behavior of struts under different boundary conditions. Results show that temperature changes can cause bending in the struts, with the glass transition temperature influencing the direction of bending.

Summary: This study investigates the impact of macromolecular architecture on the isomerization efficiency of main-chain-incorporated chromophores in both solution and solid state. It is found that branched architectures deliver the highest isomerization efficiency in the solid state, reaching up to 70% compared to solution. The macromolecular design principles established in this study can serve as a blueprint for enhancing the solid-state isomerization efficiency in other polymer systems.

Summary: The chitosan/bis(2-hydroxyethyl)methyl tallow ammonium modified montmorillonite nanocomposites were synthesized via the phase inversion procedure with the assistance of carbon dioxide. The results showed that the incorporation of CO2 reduced the viscosity of the CS/formic acid solution, while the addition of TCN increased the viscosity. The presence of CO2 enhanced the interaction between TCN and carbamic acid, leading to improved mechanical properties of the nanocomposites.

Summary: Temperature-dependent form II to I transition was investigated in low-molar-mass polybutene-1 using fast scanning calorimetry. The crystals formed in the as-crystallized sample had wide distributions of lamellar thickness and intercrystalline link densities, with the well-crystallized form II crystals showing mobility of chain segments even below the glass transition temperature. The transition from form II to form I occurred over a wide temperature range, with form I crystals transformed below the glass transition temperature having higher melting points.

Summary: Polyesters with furan groups have attracted attention due to the renewability of furan containing monomers. In this study, 11 diols were evaluated in polymerizations with the dimethyl ester of 2,5-furandicarboxylic acid, and 8 of them were found to be novel. The results showed that the glass transition temperatures of these polyesters could be controlled over a wide range by selecting specifically substituted diols.

Summary: The mechanical glass transition temperature (T-g) of dried Cronobacter sakazakii cells varied depending on differences in drying methods and water activity levels. The difference between T-g and storage temperature can serve as an integrated index for survival of bacterial cells under a desiccation environment, impacting the optimization of dry food processing. The relationship between T-g and storage temperature contributes to understanding the desiccation tolerance of bacterial cells.

Summary: An all-optical temperature sensor based on fluorescence intensity ratio was proposed for real-time monitoring of temperature in chemical reaction processes. The sensor probe was made of Er3+/Yb3+ co-doped glass and combined with an all-optical sensor system using a discharge melting method. The sensor demonstrated a maximum temperature sensitivity of 0.0067 K-1 and was successfully applied in an actual chemical reaction.

Summary: In this study, we utilized the photoisomerization of azobenzene compound triggered by UV light and thermal treatment to fabricate multimodal readable and rewritable data matrix-based devices. The UV light sensing capabilities were monitored through changes in optical, spectroscopic, and electrical properties. By integrating tetra(azobenzene)methane crystals in micrometric tags, the information could be modified and repristinated through local UV treatment and thermal annealing.

Summary: Rubbing was used on thiophene-based organic semiconductor thin films to induce reversible mechanical amorphisation, which is associated with fluorescence switching regulated by the film's polymorphic nature. Thermal annealing of the films produced an opposite effect, inducing film crystallization starting at a low temperature and generating a stable polymorph at high temperatures in the bulk. The mechanism of mechanical transformation was explained considering the material's mechanical properties and demonstrated through X-ray diffraction, atomic force microscopy, and photoluminescence at confocal microscopy.
