Summary: The addition of CF and PTFE have significant effects on the mechanical, electrical, and tribological properties of CF-reinforced PC composites. While the incorporation of 15wt% CF increases tensile and flexural strength, the addition of PTFE has a negative impact. PTFE addition reduces friction coefficient and wear rate, and the combination of 15wt% CF and 10wt% PTFE shows the best improvement in electrical resistivity. Scanning electron microscopy was used to further understand the fracture and wear mechanisms of the composites.

Summary: The impact of carbon nanopowder filler on the wear and thermal performance of the chopped strand mat E-glass fiber-reinforced epoxy composite (GFREC) was analyzed in this investigation. The addition of carbon nanopowder has a substantial impact on the wear behavior of composites, mainly due to the homogeneity created by the carbon nanofillers in uniformly dispersing the reinforcements in the matrix phase. The optimal parameters for efficient reduction of specific wear rate were found to be a load of 1.005 kg, a sliding velocity of 1.499 m/s, a sliding distance of 150 m, and 15 wt% of filler.

Summary: A pH stimuli-responsive pesticide delivery system was developed by spray drying and ion cross-linking to coat chitosan onto tebuconazole-loaded mesoporous silica nanoparticles. The loading capacity of the coated nanoparticles for tebuconazole was approximately 25.80%. The chitosan coating extended the release time of tebuconazole and exhibited pH-responsive release. The system showed enhanced control of Fusarium graminearum and lower phytotoxicity compared to pure tebuconazole during wheat germination and seeding growth experiments.
