Seeking an alternative to cerium phosphate, which increases particle size but lacks catalytic activity, we synthesized a novel cerium hydroxide-cerium oxide pigment by coprecipitating a small amount of phosphate. We chose a baseline Ce/P ratio of 10:1 based on preliminary tests showing that a moderate level of phosphate effectively reduces oxidation catalytic activity while still preserving key cerium oxide characteristics. We evaluated its composition, particle size, oxidation catalyst activity, and hue. Coprecipitation and subsequent heating yielded a yellowish pigment containing both cerium oxide and cerium phosphate. Compared to cerium oxide, our pigment exhibited superior smoothness. Additionally, samples prepared under low pH or high phosphate ratios demonstrated reduced oxidation catalytic activity. However, when applied as a pigment in oil paints, its hiding power was diminished. Our findings highlight a promising strategy for mitigating the catalytic drawbacks of cerium oxide while improving pigment properties, yet caution is warranted regarding its efficacy in paint applications. This study underscores the potential of cerium-based compounds in diverse fields, with room for optimization in specific applications.

In this study, HA powders were synthesized using waste oyster shells as a calcium source via a hydrothermal reaction at temperatures ranging from 100 to 200 °C. The influence of these temperatures on the morphology, particle size, and crystallinity of the synthesized products was examined. The crystallinity of the HA increased from approximately 22% for the room-temperature precipitation method to 38%–64% for the hydrothermal method, reflecting enhanced crystallinity with increasing temperature. X-ray diffraction (XRD) confirmed that the product was a pure HA phase, with no residual raw materials. Scanning electron microscopy (SEM) revealed that the HA particles synthesized hydrothermally were larger than those obtained by precipitation, with lengths ranging from 165 to 212 nm, widths from 26 to 41 nm, and aspect ratios between 5.2 and 6.3, compared to precipitation method particles which had lengths of 156 nm, widths of 24 nm, and an average aspect ratio of 6.7. Energy-dispersive X-ray spectroscopy (EDS) analysis indicated that the Ca/P ratios of the HA synthesized through hydrothermal synthesis ranged from 1.94 to 2.12, suggesting a Ca-rich structure. After immersion in simulated body fluid (SBF), needle-like apatite deposits were observed on the HA surface, demonstrating good bioactivity. Furthermore, osteoblast culture experiments confirmed the HA’s non-toxic nature, with the cells showing excellent attachment and growth.

The materials used include PLA pellets (Mw = 207,000 g/mol) and PCL polymer (Mn = 95 kDa). Cardanol oil were utilized as compatibilization and reinforcing agents. Composite films were prepared using a film casting method with varying concentrations of PCL (8, 10, 12 wt.%), cardanol oil (5, 10, 15 wt.%), and nanosilica (1, 3, 5 wt.%) based on the L9 orthogonal design. The produced films, with thicknesses ranging from 85 to 100 microns, were conditioned at 50% relative humidity and 25 °C to stabilize their properties. The key findings reveal that the optimal combination of process parameters, A2B1C3 (10 wt.% PCL, 5 wt.% cardanol oil, and 5 wt.% nanosilica), significantly enhanced the mechanical properties, achieving a tensile strength of 91.47 MPa and hydrophobicity of 95.25°, showing a 2.57% improvement in Grey Relational Grade (GRG). These results underscore the effectiveness of using cardanol oil and nanosilica to improve the compatibility and performance of PLA/PCL blends, providing valuable insights for developing sustainable biocomposite films for packaging applications. The FTIR analysis demonstrated effective compatibility between PLA/PCL and the added components, with distinctive peaks at 2900 cm⁻¹ and 3300 cm⁻¹ indicating CH alkyl bonds and OH phenolic groups, respectively. Morphological analysis using SEM images confirmed a uniform distribution of nanosilica and cardanol oil within the PLA/PCL matrix, which enhanced the composite’s properties, although minor submicron gaps and pits were observed. Unlike previous studies, this did not explore the ideal amounts or combined effects of these additives. This work employs a systematic approach using the Taguchi L9 orthogonal array to determine optimal input process parameters. However, this study has certain limitations like requirement of raw material for mass production of biosilica, and limited properties are studied under optimization in this study.

First the biomass extracted biocarbon was prepared by under slow pyrolysis technique. The composite fabrication was carried out using a hand layup method with careful mixing of biocarbon from Moringa oleifera husks and uniform dispersion of bagasse microfibers, ensuring enhanced composite performance.Further, to evaluate their performance, as per ASTM standard the composite specimen is cut under abrasive water jet machine. Based on the result obtained, the composite specimen, VB2, with 2 vol.% biocarbon and 40 vol.% bagasse microfibre, exhibited superior tensile strength (135 MPa), flexural strength (155 MPa), and hardness (83 Shore-D), due to optimal filler-matrix interaction and effective stress transfer. Dielectric permittivity was also highest for VB2, reaching 6.1 at 8 GHz, and maintaining higher values across other frequencies, indicating strong interfacial polarization. For EMI shielding, VB2 achieved the highest total shielding effectiveness of 31.5 dB at 8 GHz and 68.25 dB at 18 GHz, driven by the combined effects of enhanced absorption and reflection through synergistic filler effects. SEM analysis confirmed that VB2 had a uniform dispersion of fillers, minimizing voids and agglomerations, which is crucial for maximizing mechanical strength and electromagnetic shielding.

The results of rheological tests showed that the addition of nanoparticles decreased the flowability of SCC. The results of the density showed that the sample containing 4 wt% of MgO processed in the water environment had the lowest density and the sample processed in the CO₂ environment had the highest density. In the samples containing SiO₂ nanoparticles, an increase in density was observed with the increase of SiO₂ nanoparticles in both cases.
