“…In order to study the influence of hydrothermal treatment, silane coupling agent modification, and enzyme treatment on the chemical structure of the SF surface, the samples were characterized by FT-IR. As shown in Figure 4, the FT-IR spectra of raw rice straw fiber show characteristic bands within the selected region, including a band at 3,450 cm −1 attributed to the stretching vibration absorption peak of the -OH group (Tan et al, 2022), a peak at 2970 cm −1 for -CH 2stretching vibrations (Mo et al, 2019), the peaks at 1,600 cm −1 and 1,486 cm −1 corresponding to the skeleton vibration absorption of the aromatic ring of lignin (Cheng et al, 2016), and a peak at 1,055 cm −1 belonging to the characteristic absorption peak of the hemicellulose ether bond (Liang and Wang, 2017).…”

Plant straw fibers have been used widely in composite materials as reinforcement due to their advantages of low density, easy degradation, low cost, and abundance. However, the mechanical properties and water resistance of the as-prepared composites are limited due to the poor compatibility between plant straw fibers and polymer matrix. In this work, the rice straw fibers were pretreated with the silane coupling agent, lipase, and hydrothermal, and then blended with phenolic resin to prepare composites. The results showed that the pretreatment of the fibers can improve their compatibility with the resin matrix and improve the comprehensive mechanical properties and the thickness swelling of composites. When the mass ratio of fiber to resin is 1:1 and the hot-pressing condition is 160°C and 11 min, the static bending strength, elastic modulus, and thickness swelling of the phenolic resin/lipase-treatment rice straw fibers (PF/L-SF) composite reached 23.03 MPa and 2588.39 MPa, which increased by 32.9% and 30.5% compared with the unmodified fiber/phenolic resin composite (PF/SF).

“…The growing requirement for crop productivity has aroused intensive attention to nutrient management. Significant progress has been achieved in phosphate adsorption from water by assembling LDHs on other functional materials to surmount the limitations of bare LDHs . Polyvinyl alcohol (PVA) can be gelled to hydrogels through a simple physical or chemical cross-linking process .…”

Hunger and undernourishment are increasing global challenges as the world’s population continuously grows. Consequently, boosting productivity must be implemented to reach the global population’s food demand and avoid deforestation. The current promising agricultural practice without herbicides and pesticides is fertilizer management, particularly that of phosphorus fertilizers. Layered double hydroxides (LDHs) have recently emerged as favorable materials in phosphate removal, with practical application possibilities in nanofertilizers. This review discusses the fundamental aspects of phosphate removal/recycling mechanisms and highlights the current endeavors on the development of phosphate-selective sorbents using LDH-based materials. Specific emphasis is provided on the progress in designing LDHs as the slow release of phosphate fertilizers reveals their relevance in making agro-practices more ecologically sound. Relevant pioneering efforts have been briefly reviewed, along with a discussion of perspectives on the potential of LDHs as green nanomaterials to improve food productivity with low eco-impacts.

Nowadays, membrane technology is an efficient process for separating compounds with minimal structural abrasion; however, the manufacture of membranes still has several drawbacks to being profitable and competitive commercially under an environmentally friendly approach. In this sense, this review focuses on bio-based polymeric membranes as an alternative to solve the environmental concern caused by the use of polymeric materials of fossil origin. The fabrication of bio-based polymeric membranes is explained through a general description of elements such as the selection of bio-based polymers, the preparation methods, the usefulness of additives, the search for green solvents, and the characterization of the membranes. The advantages and disadvantages of bio-based polymeric membranes are discussed, and the application of bio-based membranes to recover organic and inorganic contaminants is also discussed.
