“…Natural materials such as wood, bamboo, vegetable oils, 14,15 and straw are commonly used as fillers in composites for their low cost and renewable nature. 16 Synthetic materials such as carbon fibers, 17,18 glass fibers, 19 and Kevlar are preferred for their high strength and durability. The bonding between the matrix and the additives/fillers is critical in determining the overall strength and durability of the composite.…”

In this investigation, the examination revolves around the characterization of diatomite-enhanced modified safflower oil (MSO)-derived polyester biocomposites. The primary objective is to explore the feasibility of these biocomposites as a substitute for petrochemical-based unsaturated polyester (UP) materials, with the overarching goal of enhancing their economic sustainability. Experimental data analysis employed Response Surface Methodology (RSM) and Artificial Neural Network (ANN), uncovering the optimal composition for the polyester biocomposite to be 6.7 wt.% MSO and 4.5 wt.% diatomite. During the RSM analysis, it was noted that the response parameters exhibited quadratic p-values, specifically, for density ( p < .0001), thermal conductivity ( p < .0001), and Shore D hardness ( p < .0003). However, higher ratios of MSO lead to decreased hardness and increased curing time. SEM images reveal a detrimental impact on the surface morphology of the polyester biocomposite when the diatomite content reaches 8 wt.%. Additionally, Fourier Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Analysis (TGA) offer valuable insights into the chemical bond structure and thermal behavior of the biocomposite, respectively. The Cure Index (CI) value for the diatomite-enhanced composite was determined to be 0.925, indicating a favorable contribution to the polyester curing process. The study finds that diatomite contributes to a linear change in the thermal conductivity coefficient, making the biocomposite suitable for use in the insulation industry. Overall, the study suggests that diatomite reinforced MSO-based polyester biocomposites have the potential as an alternative to petrochemical unsaturated polyester.

“…Currently, vaporized butanol can be effectively separated from the mixture without compromising productivity using pervaporation, a method that relies on temperature and pressure gradients to drive the butanol through a membrane. [ 60 ] The nanocomposite membranes developed for this purpose are constructed from a polymer with intrinsic microporosity and functionalized carbon black nanoparticles, which enhance membrane hydrophobicity, resistance to swelling, and separation efficiency compared to pristine polymer membranes. [ 61 ] These hybrid membranes also hold promise for constructing membrane reactors that can directly extract butanol from fermentation broth.…”

“…CQDs are smaller than 10 nm in size with photoluminescence properties of nanomaterials, and CQDs have low cost, easy synthesis, adjustable fluorescence, good water solubility and biocompatibility and other excellent properties. Therefore, CQDs are widely used in biological sensing, , drug testing, ion sensing, biological imaging, and pesticide detection, etc. In the synthesis process of CQDs, a variety of biomass materials can be used, such as the capsids of viruses and algae, since the biomass itself may contain heteroatoms such as N, P, and S, which makes biomass CQDs have self-doping characteristics .…”

Currently, the large-scale application of carbon quantum dots (CQDs) is usually limited by their low quantum yield and detection limit. Herein, the abandoned longan nucleus was used as a carbon source to synthesize cerium–nitrogen-codoped carbon quantum dots (Ce/N-CQDs) with strong luminescence intensity. In this work, the fluorescent properties and fluorescent quantum yield of CQDs may be improved by the single cerium-doped carbon quantum dots (Ce-CQDs) and the single nitrogen-doped carbon quantum dots (N-CQDs). Nevertheless, the Ce/N-CQDs exhibited intense fluorescence with a high quantum yield. Compared with CQDs, the quantum yield of Ce/N-CQDs was significantly increased from 5 to 32% and showed high photostability and good water solubility. The Ce/N-CQDs can be used for the direct detection of rifampicin (RFP) in human serum. The concentration demonstrated a good linear relationship in the range of 1.0 × 10 –7 –9.0 × 10 –6 mol/L, with a detection limit of 9.6 × 10 –8 mol/L.
