However, these fine grains are prone to coarsen during subsequent heat treatment, limiting the application of AFSDed materials. In this study, sub-micron TiB₂ particles with different contents (3.5 wt.% and 8 wt.%) were introduced to modify the microstructure and tailor the mechanical/corrosion properties of Al–Zn–Mg–Cu alloys. Compared with the typical 7055 aluminum alloy, the TiB₂ particles led to great grain refinement by promotion of recrystallization and significantly enhanced the thermal stability of two TiB₂/7055 composites during heat treatment. Meanwhile, the particles could alter the precipitation behavior during aging treatment, resulting in the formation of interface precipitates, a discontinuous distribution of grain boundary precipitates, and a narrower precipitate-free zone. An exceptional combination of mechanical and corrosion properties was achieved by particle addition, where 3.5 wt.% particle addition could enhance both strength and ductility of alloy, with a reduction in intergranular corrosion resistance, and 8 wt.% particle addition would enhance the strength and intergranular corrosion resistance, with a slight decrease in ductility. According to microstructure characterization, the underlying mechanism regarding the effects of sub-micron TiB₂ particles on grain structure and its thermal stability was deeply revealed. The comprehensive effects of particle contents on the mechanical properties and corrosion behavior were discussed.

The biochar composite was prepared using a straightforward in-situ chemical polymerization approach. The properties of biochar were modified by blending it with polyaniline at 25%, 50%, and 75% (w/w), successfully loaded into the biochar samples.

This PANI-modified biochar material exhibited exceptional adsorption capacity for Cr(VI) removal from aqueous samples, reaching 877.19 mg/g at 318.15 K, emphasizing its potential for water adsorption treatments. Our research in the kinetics of Cr(VI) removal showed that both pseudo-second-order and Langmuir models adequately described the adsorption process. Regeneration experiments demonstrated that, even after undergoing five cycles, BC@PANI showed 82.5% Cr(VI) removal indicating its exceptional reusability and stability.
