Summary: This study investigates a method for synthesizing gamma-Fe2O3@SiO2 nanoparticles using sodium silicate (Na2SiO3) as a precursor. A surface treatment involving an acid or base is utilized to prepare activation sites for grafting the SiO2 network onto the magnetic particles. The effects of pH on the surface charge and coating layer thickness of the nanoparticles are analyzed, and the optimal pH is determined. The resulting nanoparticles exhibit improved dispersibility and are evaluated for DNA purification. Residual Na ions on the particle surface can reduce the purification efficiency, so additional acid treatment is performed to remove them. The correlation between surface charge and interparticle forces is examined, and it is found that the purification efficiency improves as the zeta potential and particle size distribution increase. In conclusion, gamma-Fe2O3@Na2SiO3 nanoparticles are successfully fabricated using Na2SiO3 and additional acid treatment, providing a promising alternative method for synthesizing gamma-Fe2O3@SiO2 nanoparticles with improved dispersibility and purification efficiency.

Summary: A delicate synthesis strategy of Fe2TiO5/Fe2O3 heterostructures was proposed to achieve efficient photocatalytic water oxidation, with the hierarchical structure increasing light absorption depth and promoting the separation of photoinduced excitons, while the high surface area and adequate porosity facilitated the diffusion of electrolyte and adsorption at active sites. Furthermore, the coating of Fe2TiO5/Fe2O3 with graphitic carbon nitride subunits improved photocatalytic water reduction by accelerating the separation of electrons and holes at the contact interface.

Summary: A Cu/Cr-BDC@gamma-Al2O3 granular bimetal-organic framework was successfully synthesized, and its adsorption performance for thiophene from isooctane was investigated. The bimetallic adsorbent exhibited better performance due to the synergistic effects of simultaneous metal presence, and the granular adsorbent prevented particle agglomeration. The highest adsorption percentage and adsorbent capacity were 84% and 55 mg/g, respectively. The adsorption mechanism was determined to be monolayer chemisorption based on experimental data fitting with kinetic and isotherm models, and the adsorbents could be regenerated up to 5 times.

Summary: This study presents a novel electrospun fiber adsorbents with high efficiency for capturing iodine species. The adsorbents can effectively remove iodine from both saturated iodine solution and iodide solution. The high iodine uptake capacity is attributed to the multiple active sites on the adsorbents, which exhibit high binding affinity towards iodine species through physical and chemical adsorption. Additionally, the adsorbents can be used as an adsorption column for dynamic iodine capture due to their macroscopic architecture.

Summary: The development of efficient adsorbents with anti-biofouling properties for uranium extraction from seawater is highly attractive. Inspired by the structures of phospholipid, the bio-inspired zwitterionic phosphate groups were created onto the electrospun nanofibers to manipulate the affinity with uranium and the anti-biofouling property. The constructed hyperbranched zwitterionic phosphate groups functionalized nanofiber adsorbents (ZP-PAN fibers) exhibited high distribution coefficient k(d) (7.38 x 10(6) mL/g) and large adsorption capacity (1294.0 mg g(-1)) in the uranium-spiked seawater, surpassing most of reported polymeric adsorbents.
