Summary: This study analyzed a magnetite-chitosan composite through various techniques and explored its adsorption properties for Cu(II) and Cd(II). The results showed that the optimum pH for adsorption was 5.0, the equilibrium time was about 10 minutes, and the adsorption capacity reached 26.28 mg/g for Cu(II) and 18.67 mg/g for Cd(II). The temperature had a certain impact on the adsorption amount, and the composite material had a relatively rough outer surface, with dominant adsorption being attributed to chitosan. The research suggests the importance of further optimizing the composite system through green synthesis for heavy metal adsorption.

The composite microsphere exhibited good crystallinity, high specific surface area, multi-pore size distribution, better thermal stability, and more active groups. The adsorption process followed Langmuir model and Pseudo 2nd kinetics model. Moreover, the composite microsphere showed excellent antibacterial properties and maintained high adsorption rates after multiple cycles.

Summary: In this study, magnetic composite microspheres (SCFP) were successfully prepared and used for the removal of Cu(II) from water. Batch experiments revealed that SCFP exhibited excellent adsorption capacity with a removal rate of 97.1% for Cu(II). Comprehensive analysis of the structure and adsorption mechanism of SCFP provided insights into its superior performance. These findings suggest the potential of SCFP for the removal of Cu(II) from water.

Summary: In this study, well-defined powder micro-granules with interstitial nanopores were achieved through one-step evaporative jamming of colloidal silica particles in contact-free spray droplets. The anomalous freezing behavior of confined water in these microspheres synthesized using spray drying was investigated, revealing a significant lowering of the freezing point to around -45 degrees C due to the confinement effect. The results from thermoporometry were supported by structural details obtained through gas adsorption measurements and small-angle x-ray scattering.

Summary: The study investigated the influence of cupric ions on chitosan-copper complex microspheres, finding that an increase in Cu2+ concentration resulted in smaller microsphere size and altered morphology. The interaction between Cu2+ ions and chitosan atoms was confirmed through measurements of dynamic viscosity and infrared spectroscopy. Ultimately, uniformly sized and stable microspheres were successfully prepared through electrospraying in aqueous medium.

Summary: Phase-pure ZnMn2O4 nanopowders and their aggregated microsphere powders were successfully obtained by a simple spray drying process followed by post-annealing. The optimized post-annealing temperature of 800 degrees C resulted in ZnMn2O4 nanopowders with high capacity and good cycle performance. The aggregated ZnMn2O4 microsphere exhibited improved cycle stability, with a capacity retention of 84% after the second cycle.

Summary: The study examined the responses of GPP to drought in China over the last four decades and found that different climate regions and vegetation types have varying time-scales of response to drought. Grasslands and croplands tend to respond to drought at shorter time-scales compared to forests, shrublands, and sparse vegetation.
