Summary: This study focuses on the closed-loop recycling of wood flour/poly(vinyl chloride) composites and evaluates its effects on the material properties. The recycled composites showed reduced bending strength, modulus of elasticity, and impact strength, except for those recycled four times. However, the impact strength remained almost unchanged after the first recycling cycle. The water absorption rate of the reprocessed composites was generally lower, and the hemicellulose hydroxyl groups also decreased, making the recycled composites less hydrophilic. The mechanical loss factor of the reprocessed composites increased, indicating a more viscous nature. The glass transition temperature of Rec4 composites increased due to polymer dehydrochlorination and cross-linking.

Summary: The development of eco-friendly packaging materials, such as bioplastics, has been driven by the accumulation of plastic waste and the rapid reduction of fossil reserves. However, most bioplastics are manufactured with nondegradable chemical additives. Therefore, researchers have developed bioplastics from renewable and biodegradable sources by incorporating cellulose, gelatine, and chitosan. This study examines the optical properties, moisture content, swelling behavior, assessment as packaging materials, and biodegradability tests of these bioplastics, indicating that improvements in certain properties can contribute to slower degradation.

Summary: In this study, the energy absorption characteristics of oil palm empty fruit bunch (OPEFB)-reinforced composites were investigated using a low-velocity impact test. Two sets of specimens with different fiber/epoxy fractions (30:70 and 40:60) were analyzed, with one set treated with a 3% NaOH solution. The results showed that the untreated specimens absorbed more energy but suffered severe damage compared to the treated specimens, indicating that the treatment improved the interlocking mechanism and energy dissipation. Additionally, composites with a higher fiber loading exhibited slightly better energy absorption.

Summary: This study investigates the shape memory properties of a shape memory epoxy polymer (SMEP) nanocomposite incorporated with a hybrid of multi-walled carbon nanotube (MWCNT) and montmorillonite nanoclay (MMT). The nanocomposites were characterized through cyclic thermomechanical tests and fold-deploy tests. The inclusion of the hybrid nanofiller resulted in a decrease in shape recovery, except for the SMEP nanocomposite. The recovery through thermal and electrically activated methods showed similar profiles, with electrically activated recovery reacting faster. The effect of nanofiller inclusion was more prominent in the thermal activation method. The hybrid filler SMEP nanocomposite with 3 wt.% MMT and 1.0 wt.% MWCNT exhibited better shape memory properties. These findings provide guidance for selecting nanofiller loadings based on performance for specific applications in industries such as aerospace, medical, and automotive.

Summary: This study investigates the effect of ultrasonic pre-treatment on the annealing and growth temperatures of zinc oxide (ZnO) nanorods. Ultrasonic pre-treatment allowed for successful growth of ZnO nanorods at a low annealing temperature of 40°C. The size and density of ZnO nanorods increased with longer ultrasonic treatment duration, as observed through scanning electron microscopy. Additionally, the conductivity and acidity of the treated solution increased with longer ultrasonic treatment, and the zinc nutrient concentration was also affected, influencing the formation of ZnO nanorods. The annealing temperature influenced the nucleation sites essential for ZnO nanorod expansion.

Summary: Petrochemical plants often use on-stream inspection to monitor corrosion in equipment and piping systems. Phased array corrosion mapping is a more effective method compared to other techniques in detecting both general and localized corrosion. The objective of this paper is to gather evidence for the accuracy of corrosion detection on A36 low-carbon steel within a temperature range of 30°C to 250°C using simulation experiments. Although the experiments addressed initial concerns, further studies should expand the investigation to include thicker carbon steel, stainless steel, and other materials.

Summary: This study investigates the performance of composite pressure vessels under damaged and undamaged conditions, providing insights into their reliability and residual strength capabilities. The results demonstrate that the damage profile and its effect on compressive strength are similar between damaged and non-damaged cylinders. When subjected to quasi-static compression, the polyethylene liner absorbs enough elastic strain energy to recover without plastic deformation. Additionally, quasi-static compression has little to no influence on the axial strength of the cylinders. The damage characterization reveals fiber breakage, delamination, local buckling, and brooming failure. This study has direct implications for the safety design tolerances, manufacturing strategies, and operational failure conditions of composite overwrapped pressure vessels (COPVs).
