However, their reliability in harsh seawater conditions is a concern. Researchers address this by exploring three approaches: coating fiber surfaces, hybridizing fibers and matrices with or without nanofillers, and interply rearrangement. This study focuses on evaluating the synergistic effects of interply rearrangement of glass/carbon fibers and hybrid nanofillers, specifically Multi-walled carbon nanotubes (MWCNT) and Halloysite nanotubes (HNT). The aim is to enhance impact properties by minimizing moisture absorption. Hybrid nanocomposites with equal-weight proportions of two nanofillers: 0 wt.%, 1 wt.%, and 2 wt.% were exposed to seawater for 90 days. Experimental data was subjected to modelling through the application of Predictive Fick’s Law. The study found that the hybrid composite containing 2 wt.% hybrid nanofillers exhibited a 22.10% increase in impact performance compared to non-modified counterparts. After 90 days of seawater aging, the material exhibited enhanced resistance to moisture absorption (15.74%) and minimal reduction in impact strength (8.52%) compared to its dry strength, with lower diffusion coefficients.展开更多

It is characterised by the presence of Von Hansemann cells and intracytoplasmic inclusion bodies called Michaelis-Gutmann Bodies. Testes are affected in 12% cases. The lesion mainly occurs in middle aged men, appearing clinically as epididymo-orchitis or testicular enlargement with fibrous consistency and some soft areas. Orchidectomy is the only way to differentiate the lesion from other malignant or infected processes. This is a case report of a young patient with testicular malakoplakia.展开更多
