“…The presence of silicon oxide in the green tape is related to the chemical composition of the SCBA waste, as seen in the XRF spectroscopy. We observed that the SiO 2 peak positions are following the literature 43,44,45 . The α‐alumina phase comes from the powder Al 2 O 3 , which is in agreement with the results found in the literature 46,47,48 .…”

High-temperature co-fired ceramic (HTCC) technology has attracted increasing attention due to its cost-benefit ratio and excellent working capacity in adverse temperature environments, 1,2,3 applying to components of gas turbine engines for high-temperature aircraft. 4,5 Typically, fibers ceramic matrices are commonly used in exhaust structures in these turbines, presenting irregular and low hardness surfaces, which generate insufficient resistance to wear and erosion. 6,7 Thus, it is necessary to develop ceramic substrates that serve as protective covers for these materials. 8,9 We commonly use alumina ceramic matrices as the material for substrates and packages because of their excellent mechanical and thermal properties, high dielectric strength, high resistivity, and thermal and chemical stability. 10,11 However, the use of pure alumina nanoparticles is limited for this purpose, considering that its sintering temperature for dense bodies occurs above 1350°C. 12,13 The incorporation of industrial waste such as from the sugarcane bagasse ash (SCBA) into the alumina substrate serves as a flux, decreasing the sintering temperature. 14,15 Generally, waste will have discarded outdoors, causing significant environmental problems, affecting flora, fauna, and people's

“…There are two kinds of SCMs: pozzolans and fillers. The pozzolans are commonly used due to their ability to react, during cement hydration, to improve the performances of the cementitious materials [5][6][7][8][9][10][11][12]. These materials contain amorphous silica and alumina which can react with portlandite (CH) to form additional hydrated calcium silicates (C-S-H) and/or hydrated calcium aluminasilicates (C-A-S-H) and possibly other types of hydrates [12][13][14][15][16][17][18][19].…”

This study explored the pozzolanic reactivity of granite powder (GP) and its influence on the microstructure of cement paste. An analysis of the physical properties (water demand, setting time, heat of hydration and total shrinkage), compressive strength and durability indicators (water absorption, porosity, acid attack and chloride ions diffusion) was carried out on mortar containing 10%, 15% and 20% of GP as partial substitution to cement (CEM I 42.5 R) in the short and long term. The results showed that the GP does not exhibit pozzolanic reactivity and that it reduces the heat of hydration. Water demand and setting time were not affected by the GP. The compressive strength decreases with increasing the content of GP; but in the long term, the compressive strength was not affected for 10% GP substitution. The presence of granite powder in mortar induces an increase in porosity, which led to an increase in the diffusion properties of fluids (capillary water absorption and chloride ions diffusion).

“…Internationally, it was projected that around 540 million tons per year of SCB is produced [ 35 ]. In the sugar mill, the sugarcane collected from agriculture is squashed for juice extraction and the obtained fibrous residual substance of sugarcane is termed as bagasse [ 36 ]. Scheme 1 describes the flow of obtaining SCB from agricultural sources.…”

Supermagnetic Sugarcane Bagasse Hydrochar for Enhanced Osteoconduction in Human Adipose Tissue-Derived Mesenchymal Stem Cells

Hydrothermally carbonized sugarcane bagasse (SCB) has exceptional surface properties. Looking at the huge amount of SCB produced, its biocompatible nature, cheap-cost for carbonization, and its easy functionalization can give impeccable nano-biomaterials for tissue engineering applications. Herein, sugarcane bagasse was converted into hydrochar (SCB-H) by hydrothermal carbonation. The SCB-H produced was further modified with iron oxide (Fe3O4) nanoparticles (denoted as SCB-H@Fe3O4). Facile synthesized nano-bio-composites were characterized by SEM, HR-TEM, XRD, FT-IR, XPS, TGA, and VSM analysis. Bare Fe3O4 nanoparticles (NPs), SCB-H, and SCB-H@Fe3O4 were tested for cytocompatibility and osteoconduction enhancement of human adipose tissue-derived mesenchymal stem cells (hADMSCs). The results confirmed the cytocompatible and nontoxic nature of SCB-H@Fe3O4. SCB-H did not show enhancement in osteoconduction, whilst on the other hand, Fe3O4 NPs exhibited a 0.5-fold increase in the osteoconduction of hADMSCs. However, SCB-H@Fe3O4 demonstrated an excellent enhancement in osteoconduction of a 3-fold increase over the control, and a 2.5-fold increase over the bare Fe3O4 NPs. Correspondingly, the expression patterns assessment of osteoconduction marker genes (ALP, OCN, and RUNX2) confirmed the osteoconductive enhancement by SCB-H@Fe3O4. In the proposed mechanism, the surface of SCB-H@Fe3O4 might provide a unique topology, and anchoring to receptors of hADMSCs leads to accelerated osteogenesis. In conclusion, agriculture waste-derived sustainable materials like “SCB-H@Fe3O44” can be potentially applied in highly valued medicinal applications of stem cell differentiation.
