“…Thus, we can conclude that the wear debris generated for HDPE in our case exhibited identical patterns of flakes, surface wrinkling, or finer particles for each particular kind of wear process. Similar results can also be found in research work conducted recently 31,32,35 . We speculate that this composite abrasive wear is the result of higher incompatibility of CaCO 3 with HDPE.…”

Elastomeric polymers such as high‐density polyethylene, have a variety of desirable features, that have supplanted traditional materials. However, high‐density polyethylene (HDPE) shows inadequate wear resistance, which limits its use for industrial applications, particularly in low‐load‐bearing applications such as flexible energy harvesting devices and sensors. The current work is engrossed in investigating the influence of hybrid reinforcements CaCO3 particles and bentonite nano clay as secondary reinforcements in high‐density polyethylene (HDPE)‐based composites on the wear and friction properties. The reinforcements were melt compounded with HDPE using a Brabender mixer and sampled using an injection molding machine. The wear test (ASTM G‐99‐04) was performed by a pin‐on‐disk tribo‐tester. In comparison to a base matrix, the synthesized hybrid composite achieved the maximum improvement in wear rate of 93%. The results revealed that there is a significant improvement in wear resistance. Morphological analysis revealed that due to the encapsulation and compatibilization effect of bentonite nano clay the hybrid composite exhibited improved wear performance. The results signify the synergistic effect of filler particles resulted in sufficient bonding for stress transfer due to the encapsulation of CaCO3 by nano clay. The wear mechanism observed optically was abrasion, fatigue, and adhesion wear that changed with the change in the weight percent of nanoparticles. Finally, the prepared composite with enhanced tribological properties such as low wear rate, low friction coefficient, and enhanced morphology can be used in low load‐bearing wear applications such as turbo nanogenerators and piezo nanogenerators.Highlights Bentonite nano clay and CaCO3 dispersed homogeneously in HDPE matrix. Wear resistance of HDPE increases by reinforcing particles (nano‐clay and CaCO3). Micro‐cutting, deformations, and particle husks were the possible wear mechanism. Encapsulation effects the hybrid composite to exhibit improved wear performance.

“…The peaks at 31.5, 36.3, 46.2, 48.4, and 58.7 can be well assigned to the (011), (111), (112), (202), and (301) planes of CoP. 29,30 Interestingly, an overlap was observed in the 0.1 CoP/MoS 2 composite, indicating the mutual insertion of MoS 2 and CoP in the as-prepared photocatalyst was achieved. However, the peak intensity of either MoS 2 or CoP was lower than that of the single component, which might be due to the overlap of each other.…”

Bacterial infection and antibiotic resistance bring great trouble to anti-infective treatment. Therefore, it is urgent to develop antibacterial materials with high efficiency as alternatives. Herein, we successfully synthesized a series of peroxidase-like CoP/MoS 2 catalysts to strikingly enhance the photocatalytic antibacterial activity. After excitation by LED light, the CoP/MoS 2 heterojunction composite exhibited a photocatalytic sterilizing rate of 97.2% toward S. aureus with a concentration of 1 mg/mL. Based on the theoretical discussion and experimental result analysis, it is concluded that the sharp edges of MoS 2 nanosheets, excellent hydrophilicity of CoP/MoS 2 , and incorporation with the generation of reactive oxygen radicals endow the catalyst with rapid and effective photocatalytic bacterial killing activity. This study provides a promising strategy by using adhesive nanozymes in close proximity to the bacteria surface, which will guide the design and synthesis of heterojunction photocatalysts with nanozymes activity and high photocatalytic antibacterial efficiency.
