“…Indeed, commercially available food additive SiO 2 is manufactured by two different methods: One is precipitated SiO 2 , produced by the reaction of metal silicate solutions and sulfuric acid, resulting in white precipitates [22]. The other is fumed SiO 2 -also known as pyrogenic SiO 2 -which is produced by the flame pyrolysis of silicon tetrachloride (SiCl 4 ), or from quartz sand vaporized in an electric arc at 3000 • C [23,24]. It was reported that the dissolution and physicochemical properties of SiO 2 NPs differ between the two manufacturing methods [25,26].…”

Food additive amorphous silicon dioxide (SiO2) particles are manufactured by two different methods—precipitated and fumed procedures—which can induce different physicochemical properties and biological fates. In this study, precipitated and fumed SiO2 particles were characterized in terms of constituent particle size, hydrodynamic diameter, zeta potential, surface area, and solubility. Their fates in intestinal cells, intestinal barriers, and tissues after oral administration in rats were determined by optimizing Triton X-114-based cloud point extraction (CPE). The results demonstrate that the constituent particle sizes of precipitated and fumed SiO2 particles were similar, but their aggregate states differed from biofluid types, which also affect dissolution properties. Significantly higher cellular uptake, intestinal transport amount, and tissue accumulation of precipitated SiO2 than of fumed SiO2 was found. The intracellular fates of both types of particles in intestinal cells were primarily particle forms, but slowly decomposed into ions during intestinal transport and after distribution in the liver, and completely dissolved in the bloodstream and kidneys. These findings will provide crucial information for understanding and predicting the potential toxicity of food additive SiO2 after oral intake.

“…Figure 8b shows that the thermal degradation of BF/T started at a temperature of 200 • C, while that of BF/U started at about 250 • C, with maximum decomposition temperatures of 319 and 330 • C, respectively, which can be represented as the highest peak in the DTG curves. The treated banana fibers exhibited higher resistance to thermal degradation than untreated fibers due to the removal hemicellulose, lignin, and waxy substances and rapid weight loss, indicating higher thermal stability in BF/T due to alkaline treatment [62,63]. Figure 8c,d show the TGA and DTG curves of coir fibers with and without treatment, respectively.…”

In this work, the adhesion behavior of chemically treated banana and coir Colombian fibers embedded in polylactic acid (PLA) and unsaturated polyester resin (UPR) matrices was investigated. Both types of fibers were treated with a 5 wt.% sodium hydroxide solution for one hour. The properties of treated and untreated fibers were determined by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and tensile tests. To evaluate the adhesion behavior of the fibers in PLA and UPR matrices, pull-out tests were performed, and the percentage of broken fibers was determined. The results showed that alkaline treatment improved the fibers’ physicochemical, mechanical, and thermal properties. In addition, the alkaline treatment was able to improve the adhesion behavior of coir and banana fibers to PLA and UPR matrices. The banana fibers showed a percentage of broken fibers of 100%, while the coir fibers showed a slight increase in IFSS value. This behavior is attributed to the improvement in surface roughness due to the removal of non-cellulosic composites and impurities.

“…These findings indicate that alkali concentration and treatment duration are dominant factors in achieving a better tensile strength performance. For the same alkali concentration and treatment duration, some studies ( Saha et al., 2010 ; Roy et al., 2012 ; Zafar et al., 2016 ; Maharana et al., 2020 ) have revealed a very different outcome. Additionally, studies by Zafar et al.…”

In the backdrop of an abundance of lignin in jute, the main focus of the present study was to conduct a quality assessment of four delignified jute lines (in which four lignin biosynthetic genes were individually downregulated) across advanced generations for industrial applications. To this end, the transgenic lines were advanced to 7 th (COMT and C4H lines) and 5 th (C3H and F5H lines) transformed generations. The results exhibit approximately 16–25% reduction in acid-insoluble lignin for the whole stem and 13–14% reduction in fiber lignin content for all four transgenic lines compared to the control. The altered lignin composition led to a 3–6% increase in the cellulose content and a small improvement in the enzymatic release of glucose. Lignin reduction led to an exposure of the underlying fibrils in transgenic lines as observed through a scanning electron microscope whereas, it was undiscernible in the control fiber. Furthermore, an analysis of the mechanical properties appears almost similar to that of the control with no morphological deformities. Jute fibers from the transgenic lines offer tremendous cost-effective implications from an economic perspective.
