“…27,28 Compared with other hydrogels which have three-dimensional network structures that can swell, Schiff base cross-linked hydrogels can dissolve in water. 29,30 Therefore, a Schiff-base cross-linked amphiphilic copolymer hydrogel presents the potential for a more biocompatible and biodegradable BAS with high adsorption capacity. In this paper, the properties of the novel hydrogel were investigated systematically by Scanning Electron Microscopy (SEM), rheological studies, swelling properties determination, and in vitro degradation behaviors.…”

“…Carbonation is generally carried out in a series of reactors under closely controlled operating conditions to produce the required PCC morphology and particle size distribution (PSD). Luo et al 16 studied the synthesis of vaterite PCC via carbonation route under controlled pH condition. They reported that buffer solution highly influence the polymorphic phase of PCC while CO 2 concentration and rate of gas flow have no significant influence.…”

This study investigates the effect of operating variables and influence of milk of lime (MOL) conditions in PCC using a modified reactor. The variables includes: Ca(OH) 2 feed concentration at 0.5 M-2.0 M and CO 2 flow rates at 224.0 mL min -1 and 379.5 mL min -1 , on the particle morphology and size in the gas-liquid route precipitation. The particle morphology and texture as well as the chemical content were sufficiently authenticated using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and X-ray fluorescence (XRF). Experimental data show that lower concentration (<1.0 M) favoured the formation of rhombohedra calcite crystals with the particle size below 100 nm. However, increase in concentration and gas flow rate yielded a coarser crystal particles. Two polymorphs were produced at 1 M reactant, i.e. rhombohedra calcite with CO 2 flow rate of 224 mL min -1 and prismatic calcite at 380 mL min -1 . Molarities higher than 1 M yielded a coarser prismatic crystals, and also has a tendency to crystallize into scalenohedron species especially with higher reactant concentration. KEYWORDSMilk of lime, precipitated calcium carbonate, morphology, particle size, carbonation.

Agrochemicals have supported the development of the agricultural economy and national population over the past century. However, excessive applications of agrochemicals pose threats to the environment and human health. In the last decades, nanoparticles (NPs) have been a hot topic in many fields, especially in agriculture, because of their physicochemical properties. Nevertheless, the prevalent methods for fabricating NPs are uneconomical and involve toxic reagents, hindering their extensive applications in the agricultural sector. In contrast, inspired by biological exemplifications from microbes and plants, their extract and biomass can act as a reducing and capping agent to form NPs without any toxic reagents. NPs synthesized through these bioinspired routes are cost-effective, ecofriendly, and high performing. With the development of nanotechnology, biosynthetic NPs (bioNPs) have been proven to be a substitute strategy for agrochemicals and traditional NPs in heavy-metal remediation of soil, promotion of plant growth, and management of plant disease with less toxicity and higher performance. Therefore, bioinspired synthesis of NPs will be an inevitable trend for sustainable development in agricultural fields. This critical review will demonstrate the bioinspired synthesis of NPs and discuss the influence of bioNPs on agricultural soil, crop growth, and crop diseases compared to chemical NPs or agrochemicals.
