Summary: This study investigated the influence of different processing input parameters on the heat-affected zone (HAZ) of SPF-UPE composites cut with a CO2 laser. Results showed that minimizing laser power and maximizing traverse speed and gas pressure gave the optimum HAZ response. Gas pressure had the most significant effect on the HAZ, with its contribution decreasing as material thickness increased, while the contribution of traverse speed increased with material thickness.

Summary: The study found that spreading commingled carbon fiber/nylon fiber yarns can effectively reduce the impregnation distance, with rapid nylon resin impregnation on the carbon fibers. However, an increase in molding time resulted in a slight decrease in tensile strength and tensile fracture strain, as well as degradation of the nylon resin. The effects of molding time on flexural strength, flexural modulus, and flexural fracture strain were negligible.

Summary: In the era of globalization, the decrease in synthetic resources has led global communities to explore natural fibres as alternative materials for green technology development. This study focuses on the growth of lignocellulose fibre-reinforced composites, which are abundant, sustainable, biodegradable, and low-cost. By reinforcing polyester resin with natural fibres such as sugar palm, kenaf, and bamboo, the mechanical properties and water absorption properties of the hybrid composites were investigated. The results showed that the composite with 45 wt% kenaf fibre had better tensile properties, and the composite with 60 wt% sugar palm fibre performed better in the Charpy impact strength test. The study concluded that sugar palm fibres demonstrated the best water resistance.

Summary: The study examines the use of black seed fiber as a reinforcing material for cornstarch-based biocomposites. Different concentrations of black seed fiber and a plasticizer mixture were used to fabricate the biocomposites. The results showed that increasing the black seed fiber concentration improved the mechanical properties and thermal stability of the films, but decreased biodegradability. The addition of black seed fiber has the potential to enhance the performance of biopolymers in response to community needs and environmental concerns.

Summary: This paper investigates the thermal, tensile strength, and flexural strength properties of a polyester composite filled with hybrid Eichhornia crassipes (EGs) /aluminum oxide (Al2O3) particles. The results show that the tensile and bending strengths increase when the EGs content in the composite is in the range of 10-15%. The scanning electron microscope fracture morphology reveals a strong and tight interfacial connection between the EGs, Al2O3, and polyester layers. According to the findings, this hybrid composite can be used in automotive applications.

Summary: Ultrasonication is an effective method for extracting and processing plant-based cellulose nanocrystals. It can optimize the properties of CNCs for the fabrication of sustainable materials. The parameters of ultrasonication, such as time, amplitude, and energy input, play a dominant role in reducing particle size and altering morphology. Furthermore, ultrasonication also impacts the dispersion state and surface chemistry of CNCs. This technology has important implications for the design of photonic materials using nanocrystal-based celluloses.

Summary: Chemical and biological water contamination, including heavy metals, aromatic compounds, and dyes, has become a major concern in the past three decades. To address this issue, scientists are exploring the potential of starch as an environmentally friendly material for water remediation due to its non-toxicity, biodegradability, and biocompatibility. Starch derivatives have shown effective adsorption capabilities for pollutants such as oil, organic solvents, pesticides, heavy metals, dyes, and pharmaceuticals, with removal rates exceeding 90%. However, further research is needed to optimize the technique before starch-based adsorbents can be widely used for large-scale wastewater treatment.

Summary: This study investigates the influence of hybrid reinforcements, namely CaCO3 particles and bentonite nano clay, on the wear and friction properties of high-density polyethylene (HDPE)-based composites. The results demonstrate a significant improvement in wear resistance, with the synthesized hybrid composite achieving a maximum improvement in wear rate of 93%. Morphological analysis reveals that the encapsulation and compatibilization effect of bentonite nano clay contribute to the improved wear performance. The prepared composite with enhanced tribological properties shows potential for use in low load-bearing wear applications such as turbo nanogenerators and piezo nanogenerators.
