To address the disadvantages of hydroxyl bonding, the extracted leaflet strips were treated with NaOH solution. For the formation of nanoparticles, treated rice husk (RH) samples were ground utilizing stainless steel balls in a mild steel ball mill pot. Rice husk nanoparticles (RHN) were integrated onto the treated bi-lateral leaflet fibre surface with 0.3, 0.5, 0.7, and 0.9 wt percent, utilizing silane coupling agent (KH-171). The composite samples were developed using the hand lay-up method. The developed samples were evaluated to assess the physical, mechanical, thermal, and morphological behaviour of the nanocomposites.

Synthesized materials crystallized in hexagonal unit cells with space group <em>P</em>6₃, as shown by the Pawley refinement of powder diffraction patterns recorded, confirming the vishnevite-type structure. SEM results showed small and irregular particles that form spherical aggregates in botryoidal habits, and the N₂-physisorption indicated low values of surface area and pore volume.

The surface of TNTAs was decorated with noble metals using a simple electrochemical deposition approach, while RGO, g-C₃N₄, and MOF were deposited using a dispersion method. Enhanced optical and chemical properties of modified photocatalysts were confirmed by various characterizations. Controlled architecture of TNTAs with excellent morphology was obtained, providing outstanding performance of electron transferring with enhanced sorption process. Compared to pristine TNTAs, the modified TNTAs exhibited significantly improved CO₂ reduction under visible light irradiation. And the composite photocatalyst constructed by the incorporation of g-C₃N₄ showed the highest CO₂ photoreduction with the CO and CH₄ yields of 29.69 and 2.88 µmol/cm²/h, which were 12.5 and 7-times higher that of TNTAs, respectively. The higher CO₂ photoreduction of the g-C₃N₃/TNTAs binary composite was ascribed to the synergistic action between g-C₃N₄ and TNTAs which substantially reduced the band gap energy. The modified-TNTAs' stability and recyclability also showed that there was no discernible change in photocatalytic performance throughout several cycle runs, resulting in continuous CO and CH₄ generation.

This intense ionization enables precise control over film microstructure, morphology, and elemental composition, leading to dense, smooth films with enhanced adhesion. This review begins with a comprehensive analysis of plasma dynamics in the HiPIMS process, followed by a systematic evaluation of the mechanical, tribological, and electrochemical properties of various coatings, including TiN, TiAlN, TiCN, TiSiN, TiAlCN, TiZrN, TiAlCrN, and related systems. Various Finding reveals that HiPIMS processing consistently enhances hardness, wear resistance, fracture toughness, and corrosion resistance compared to DCMS, primarily by promoting denser microstructures and beneficial residual stress. Furthermore, the incorporation of elements like Al, Si, C, Cr, and V is shown to further modify and improve properties, crucial for high-performance applications.
