Summary: Phosphorus is a crucial element for agricultural production but its non-renewable phosphate ore resources are depleting. Phosphate release from wastewater treatment plants and inefficient crop fertilization causes pollution such as water eutrophication. Therefore, phosphorus recovery from wastewater through biochar adsorption is a promising alternative agricultural phosphorus source. Biochar, with its porous structure, large surface area, abundant surface groups, and high mineral content, can effectively adsorb phosphorus. Additionally, functionalization of biochar can improve its adsorption performance.

Summary: Biochar-based fertilizers synthesized using a simple technique involving the co-pyrolysis of Ca-bentonite and chicken manure exhibit promising slow-release performance for phosphorous and potassium. The addition of Ca-bentonite significantly reduces the solubility of orthophosphates and slows down the release of potassium in soil. However, it has no significant impact on nitrogen release. The nutrient release from the biochar-based fertilizers also varies in different soil media.

Summary: In this study, ball-milled Ca-loaded biochar (BMCa@BC) composites were successfully prepared for phosphorus recovery from water bodies. BMCa@BC exhibited a high adsorption capacity of 329 mg P/g and involved various mechanisms such as hydrogen bonding, electrostatic attraction, complexation, and surface precipitation. The phosphorus recovered by BMCa@BC had high bioavailability and low loss, and showed potential as a slow-release fertilizer. After regeneration cycles, BMCa@BC still maintained good adsorption recovery, and the P-enriched desorption solution could be recovered as Ca-P products with fertilizer value. Overall, BMCa@BC showed good cost-effectiveness and practical applicability in phosphorus recovery.

Summary: The development of controlled-release fertilizer formulation is important for preventing environmental pollution caused by nutrient leaching and volatilization. This study combined biochar-based fertilizer with encapsulation technology to improve the nutrient release mechanism. Optimal conditions for synthesizing urea-impregnated biochar (UIB) were determined using central composite design, and the release of nitrogen was described by mathematical models. Results showed that encapsulated UIB (EUIB) achieved complete release of nitrogen in water and exhibited improved water retention in sandy-textural soil. Therefore, EUIB derived from peppercorn waste has the potential to be used as a sustainable controlled-release fertilizer for agriculture.

Summary: In this study, struvite-biochar was successfully created by adding coconut shell biochar and EDTA to a designed fluidized bed reactor (FBR). The release of N and P from struvite-biochar and the recovery efficiency of N and P from concentrated sludge supernatant were analyzed. The results showed that the optimal operation conditions for HRT, pH, Mg/P molar ratio, and EDTA addition amount were identified. The addition of biochar improved the recovery efficiency of N and P, but decreased the purity of the struvite product. Struvite-biochar had lower concentrations of As, Cd, Pb, and Cr compared to Chinese Standard Limits of Fertilizer. The slow release of N and P from struvite-biochar and struvite compared to commercial fertilizers was observed. The study demonstrates the value of adding biochar to FBR for N and P recovery and the production of slow-release fertilizers.

Summary: Magnesium-functionalized Magnolia grandiflora Linn leaf-derived biochar (MBC) was synthesized by slow co-pyrolysis and showed efficient phosphorus reclamation from urine. The adsorption process of phosphate-phosphorus (PO43--P) by MBC was best described by the pseudo-first-order kinetic model and multilayer model with saturation. MBC and phosphorus-saturated MBC (P-MBC) exhibited outstanding phosphorus adsorption and slow release properties respectively, and P-MBC was confirmed to be a suitable slow-release fertilizer through seed germination and early seedling growth experiments.

Summary: A new microreactor with continuous serially connected micromixers (CSCM) was developed for coprecipitation synthesis of Fe3O4 nanoparticles. Numerical simulation revealed that the V-typed and U-typed CSCM microchannels exhibited better mixing performance due to the promotion of Dean vortices. Fe3O4 nanoparticles synthesized in the V-typed microchannel possessed better dispersity, uniformity, and crystallinity compared to those obtained in the capillary microreactor. The new CSCM microreactor can be a potent device for intensifying the synthesis of similar inorganic nanoparticles.

Summary: In this study, cationic polyelectrolyte nanogels were successfully synthesized by Electrostatic Assembly Directed Polymerization (EADP) method and used to load gold nanoparticles (AuNPs). The catalytic activity of the loaded AuNPs was found to be dependent on the crosslinking degree of the nanogels, but independent on the nanogel size. This demonstrates the potential of polyelectrolyte nanogels for developing functional nanoreactors.

Summary: In this study, a flash nanoprecipitation (FNP) method using a versatile multi-inlet vortex mixer (MIVM) was used to fabricate deformable hollow mesoporous organosilica nanoparticles (HMONs). The synthesized HMONs had high surface area (571.1 m(2) g(-1)), narrow size distribution (PDI = 0.03), and large hollow cavity. The particle sizes (457-629 nm) of the HMONs could be controlled by adjusting the mixing Reynolds (Re) number. Transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS) results revealed the deformability of the HMONs in solution. The deformable HMONs, with lower Young's modulus (EY) of 53.20 MPa compared to non-deformable HMONs (176.55 MPa), showed improved affinity to the leaf surface and enhanced insecticidal activity against Meloidogyne incognita, demonstrating great potential for sustainable agricultural applications.

Summary: This study presents a facile strategy called electrostatic-templated polymerization (ETP) for synthesizing zwitterionic nanogels with controlled size and properties. By utilizing anionic-neutral diblock polymers as templates, zwitterionic monomers are polymerized together with a cross-linker at pH 2, resulting in the formation of polyelectrolyte complex micelles. These micelles can be dissociated and separated to obtain zwitterionic nanogels with regulated size and swelling ability by adjusting the salt concentration and cross-linker fraction during polymerization. The developed zwitterionic nanogels show potential applications in selective loading and intracellular delivery of charged cargo.
