This study investigated chemical treatment’s impact on mechanical and flammability properties of rice husk-reinforced recycled high-density polyethylene (r-HDPE) composites. Three treatments (maleate, alkali, acid) were applied to husk, composites tested for tensile strength, elongation at break, modulus elasticity. Results showed that strength decreased with increasing husk content, except treated maleic anhydride grafted (MAPE), which exhibited the highest 10% filler content. Break...

Dye-sensitized solar cells (DSSCs) hold promises for replacing fossil fuels in energy production through the conversion of light energy. However, use platinum (Pt) fabrication counter electrodes (CEs) DSSCs contributes to high costs. Developing efficient, platinum-free CEs has become a focus point advancing DSSC technology due drawbacks including low efficiency, electron recombination, and stability issues that limit their performance. To address this, our innovation involves Pt with...
