Summary: High-potential nanomaterials were obtained from rice straw through enzymatic hydrolysis with green organic acid hydrolysis assisted with ultrasonication pretreatment. The optimized conditions achieved a maximum nanocellulose content of 32.37% using a cellulase concentration of 107.06 U/mL and 0.13% (w/w) of rice straw cellulose. The nanocellulose content was further improved to 64.99% through integration with oxalic acid hydrolysis.

Summary: Cellulose aerogels were obtained from purified rice straw cellulose fibres using different extraction methods. The composition and properties of the fibres were significantly influenced by the purification process. The choice of extraction method had an impact on the removal of silica and hemicellulose from the fibres, which in turn affected the hydrogel formation capacity and properties of the aerogels.

Summary: This study investigated the adsorption performance of methylene blue using Ca(OH)2-modified rice straw biochar derived from agricultural and forestry wastes. The modified biochar exhibited excellent adsorption capacity for methylene blue, with a Langmuir fitting adsorption capacity 12.5 times higher than that of pristine rice straw biochar. The Ca(OH)2 modification increased the polarity, Ca content, and oxygen-containing functional groups of the biochar, enhancing the chemical adsorption of methylene blue.

Summary: Rice straw waste was used to extract natural cellulose fibers, which were chemically converted to cellulose gel. Both extracted cellulose and modified cellulose (gel) were characterized and used for biosorption of heavy metals. The results showed that the modified cellulose gel had greater metal sorption capability than extracted cellulose. The new modified biopolymer exhibited promising behavior as a sorbent for cation removal and was prepared from cheap material extracted from rice waste.

Summary: The study found that increasing the dosage of rice straw biochar (RSB) can significantly enhance the sorption of phenylurea herbicides (PUHs), while adjusting the pH and ionic strength (IS) had no obvious impact. The optimal sorption conditions were determined as pH 3, IS 0.1 M, and RSB dosage 60 mg, with maximum removal rates of 41.9%, 25%, and 56.8% for Monuron, Diuron, and Linuron, respectively. The co-transport process of RSB and PUHs was affected by RSB dosage and pH value, while the presence of RSB increased the amount of dynamic sorption sites, leading to a significant promotion of PUHs' sorption and interception.

Summary: In this study, rice straw nanofibers (RSNF) with a width of 4-5 nm were isolated and combined with zinc oxide nanoparticles (ZnONPs) to prepare flexible nanopaper films. The addition of ZnONPs slightly improved the tensile strength and Young's modulus of the RSNF nanopaper. Scanning electron microscopy (SEM) showed that ZnONPs were integrated into the RSNF. The electrical conductivity and dielectric properties of the prepared nanopaper were investigated, and it demonstrated potential for use in electronic components.
