Summary: Carbon nanotubes have great potential for use in microelectronic packaging due to their excellent thermal conductivities. However, their high electroconductibility and poor radial conductivity limit their application in insulating materials. In this study, a heterostructured brushlike hybrid was prepared by anchoring amine-functionalized multiwalled carbon nanotubes onto insulating montmorillonite. The resulting composites exhibited improved thermal conductivity, mechanical properties, and thermal stability, providing a promising strategy for fabricating polymer composites.

Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

Summary: In this study, pectin monoliths with tailored properties were prepared using different crosslinking and freeze-drying methods. The resulting pectin monoliths exhibited macroporous structures, limited surface area, moderate mechanical stability, and biodegradability. The presence of alcohol in the crosslinking solution significantly affected the morphology of the monoliths, resulting in reduced pore size. The pectin monoliths obtained through a calcium-water-alcohol route showed specific surface area of 25.7 m(2)/g, Young compressive modulus of 0.52 MPa, and biodegradation rate of 45% after 30 days of immersion in compost media. The pectin monoliths have great potential for applications in pharmaceutical, agricultural, medical, and food industries, contributing to sustainable development concepts.

Summary: In this study, chitin, a biobased polymer, was used as a precursor to obtain phosphorylated derivatives. The influence of different degrees of phosphorylation in chitin on pyrolysis pattern was investigated. Through FTIR, SEM, and Py-GC/MS analysis, the thermal degradation and evolved gases during chitin degradation and its derivatives were measured. The results showed that phosphorylation of chitin decreased its thermal stability and significantly changed the pyrolysis pattern, leading to the production of long-chain hydrocarbons.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
