Summary: By adjusting the ratio of BT to CNT, the NBR/BT composites exhibited shorter scorch time and cure time, as well as superior tensile properties and reinforcement efficiency. The NBR/BT-CNT composite with 80 phr BT and 1-2 phr CNT had a dielectric constant of 100-500, dielectric loss of 12-100, and electrical conductivity below 10(-4) S/m, along with high thermal stability.

Summary: The influence of multi-walled carbon nanotubes (MWCNTs) on the thermal, mechanical, wetting properties, and rheological behavior of poly(ethylene-co-vinyl acetate) (EVA)/acrylonitrile-butadiene rubber nanocomposites was investigated. It was found that the addition of MWCNTs improved the solid surface free energy, work of adhesion, spreading coefficient, and Girifalco-Good's interaction parameter, while reducing the contact angle and interfacial free energy. The nanocomposite with 1 wt% nanofillers exhibited the highest tensile strength and toughness. Furthermore, the relaxation ratio and relaxation rate index decreased with increasing carbon nanotubes (CNTs) concentration. The increment in MWCNTs loading led to an increase in the yield stress of the molten materials according to a quadratic equation. The analysis also showed that the crystallization process was triggered at a slightly higher temperature with the introduction of CNTs, while the melting point and nucleation rate decreased noticeably with the increase in nanofillers content.

Summary: The introduction of strong hydrogen bonding interactions significantly increases both the toughness and the tensile strength of the elastomer as well as the oil resistance, with the tensile strength and fracture toughness reaching up to 8.57 MPa and 39.12 MJ m(-3) when the mass fraction of UPy-NCO is about 2.25 wt%. The dynamically physical cross-linking networks formed by hydrogen bonds can still be continuously regenerated after being broken, dispersing stress concentration while ensuring resilience and reprocessing capability.

Summary: This study investigates the effects of thermal oxidation ageing on NBR seals, showing that it significantly impacts the rubber properties such as hardness, bulk modulus, tensile strength, and tear strength. Different ageing degrees result in distinct damage mechanisms, with the wear mechanism shifting gradually from adhesive wear to abrasive wear or fatigue and abrasive wear. Despite a decrease in average wear rate with increased ageing parameters, important mechanical properties like viscoelasticity and fracture resistance are severely reduced or lost entirely due to ageing degradation.

Summary: The basic idea of cryogenic machining of elastomers is to lower the temperature to make them brittle and easier to machine. However, the heat generated during the process can still result in a partially rubbery state. This study analyzed the effect of cryogenic cooling on milling acrylonitrile-butadiene rubber, considering different cooling setups and tool parameters. Direct cooling provided the best temperature distribution and surface roughness, while increasing the depth of cut and rotational speed increased surface roughness. The best results were achieved with specific parameters, showing clean grooves with sharp edges and minimal surface roughness.

Curing enhances the exfoliation of high OMMT content materials and improves hardness, tensile strength, and other indicators. Additionally, at a constant OMMT content, the impact of nanofillers on uncured materials is more significant than on cured materials.

Summary: Ethylene-propylene grafted-maleic anhydride (EPR-g-MA) and pure maleic anhydride (MA) were used to compound carboxylated acrylonitrile butadiene-rubber (XNBR) with reduced graphene oxide (G) to form nanocomposites using melt compounding technique. The addition of G-sheets in the presence of MA or EPR-g-MA improved the physico-mechanical properties and thermal degradation resistance. The strong bonding in the nanocomposites was found to be the main contributing factor for these property enhancements. The nanostructured materials have multifunctional capabilities and potential applications in high temperature, flame retardancy, and structural fields.

Summary: This paper investigated the effects of brewers' spent grain (BSG) extrusion parameters on the photo-oxidative resistance of poly(epsilon-caprolactone)-based wood polymer composites. Filler samples with higher melanoidin content were more effective in hindering polymer degradation and inhibiting the decomposition of the polymer amorphous phase. Therefore, deterioration of mechanical performance was limited, as indicated by higher aging factor values for samples containing BSG extruded at higher temperatures.

Summary: Recently, there has been significant interest in the development of greener and biodegradable materials due to environmental concerns. Plant fibers have gained popularity as a substitute for synthetic fibers in composites due to their low cost, biodegradability, and good mechanical properties. However, the hydrophilic nature and high-water absorption of plant fibers limit their use as a reinforcing agent in polymer matrices. Chemical treatments can help overcome this limitation. Cellulose, the most abundant natural polymer obtained from various sources, has received increased attention. Different methods, such as mechanical and chemical treatments, have been adopted by researchers to extract cellulose from plants, bacteria, algae, etc. Nanocellulose, including cellulose nanocrystals, cellulose nanofibrils, and microcrystalline cellulose, has been extracted and used in various applications. This review provides updated information on the isolation, classification, characterization, and application of nanocellulose. It also discusses the characteristics and current status of cellulose-based fiber-reinforced polymer composites in the industry.

Summary: This study investigated the multiple reprocessing of a commercially available PLA conductive composite with carbon black filler for 3D printing. The effects of extrusion temperature and reprocessing steps on the rheology, morphology, thermal, and electrochemical properties of the conductive PLA 3D-printing filament were evaluated. The results showed deterioration in thermal stability and material strength, as well as an increase in melting point after initial melting. The conduction mechanism and reversibility of the redox process were also affected by the multiple processing. Furthermore, the material fluidity was too high after multiple reprocessing, which should be considered for proper application as a 3D-printed electrode material.

Summary: In this study, ground tire rubber and styrene-butadiene block copolymer (GTR/SBS) blends were prepared with different SBS copolymer grades and cross-linking agents. The rheological and cross-linking behavior, physico-mechanical properties, thermal stability, and morphology of the blends were characterized. It was found that the selected SBS copolymers improved the processability of the blends and the type of cross-linking agent influenced the cross-linking behavior. The sulfur system cross-linked blends exhibited better tensile strength, elongation at break, and abrasion resistance compared to those cross-linked by dicumyl peroxide. Moreover, the SBS copolymers improved the thermal stability and interfacial adhesion between GTR and SBS copolymers.

Summary: The study introduces a new concept of preparing nanosilica from rice husk without concentrated mineral acids by using a bioleaching strategy to remove metallic impurities. Nanosilica (BJRHS) was prepared by calcinating Averrhoa bilimbi juice pre-treated rice husks. The chemical and atomic structures of commercial precipitated silica (CS), rice husk ash (RHA), and BJRHS were analyzed using different techniques. The results showed that BJRHS had a smaller particle size and a higher BET surface area compared to RHA and CS. Sustainable production of mesoporous nanosilica with excellent surface area and purity from rice husk is recommended for applications in catalysis, polymer technology, etc.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
