Summary: When wheat straw biochar was applied to Cd-containing solutions, Cd and Zn concentrations decreased and Ca and Mg concentrations increased, while pH also increased. Similar responses were observed when biochar was added to Cd-contaminated paddy soil, indicating biochar's ability to sequester toxic elements and release necessary nutrients. Nutrient release correlated positively over time, while biochar application rate correlated negatively with toxic element sorption and pH.

Summary: This study demonstrates that solar irradiation can enhance the reduction of mercuric Hg(II) to elemental Hg(0) by algal cells and their organic matter. Algal organic matter (AOM) was found to be more effective in reducing Hg(II) than algal cells themselves due to cell surface adsorption and uptake of Hg(II) inside the cells under solar irradiation. Additionally, sunlight facilitated the transformation of Hg to less bioavailable species compared to species formed in algal cells in the dark. These findings highlight the important functional roles and potential mechanisms of algae in Hg reduction and immobilization under varying lighting conditions.

Summary: Solid-state systems can host a variety of thermodynamic phases that are challenging to study on the nanoscale due to the coexistence of multiple phases. Coherent diffractive imaging spectroscopy (CDIS) enables nanometer-scale resolution hyperspectral imaging of vanadium oxide, extracting refractive indices of different phases from a single sample without evidence of correlation-driven phase transitions. CDIS allows quantitative full-field x-ray spectromicroscopy for studying phase separation in extreme sample environments.

Summary: Nickel based magnetic nanocrystals have wide applications in magnetic and catalytic fields. Tunable magnetic properties of nickel can be achieved through non-magnetic doping or phase transformation. This study presents a way to control the magnetism of Au@Ni-carbide magnetic materials by adjusting the amount of carbon in the Ni layer, and provides solid evidence for the carbonation process from fcc-Ni to Ni X C instead of phase transformation to hcp-Ni. Further investigation reveals that the magnetism of the hybrids is mainly contributed from the residual fcc-Ni.

Summary: Coal fly ash-based porous geopolymer (CFAPG) has potential as an adsorbent for heavy metal-contaminated water remediation and coal fly ash accumulation mitigation. The production parameters significantly influence the physicochemical properties, such as the adsorption capacity, of CFAPG. In this study, ten potential factors were examined, and the alkali activator modulus (MS), alkali-ash mass ratio (AA), foaming agent-ash mass ratio (FAR), and sodium dodecyl sulfate-ash mass ratio (SDSA) were identified as the most important factors affecting the Zn adsorption capacity of CFAPG. Ternary plots confirmed the interaction between these factors, with FAR being easily masked by other factors and MS being the least influenced. The results provide key parameters for the production of geopolymers as heavy metal adsorbents.

Summary: This study investigates the adsorption mechanisms of antimony (Sb) on iron (oxyhydr)oxides and finds that inner-sphere complexation occurs independently of pH and surface coverage. Lighter Sb isotopes are preferentially enriched on Fe (oxyhydr)oxides due to isotopic equilibrium fractionation. The results provide insights into the Sb adsorption mechanism by Fe (oxyhydr)oxides and clarify the Sb isotope fractionation mechanism, which is essential for future applications of Sb isotopes as tracers.

Summary: Coal fly ash accumulation, global warming, and heavy metal-contaminated water environments are three primary environmental concerns. Porous geopolymers, produced using coal fly ash, can be employed for heavy metal removal from water. However, residual alkalis on the geopolymer can cause environmental stresses, limiting its large-scale production and application. This study proposes CO2 exposure as a green approach to alleviate the high basicity of geopolymers, demonstrating its practicality for heavy metal-contaminated water treatment.

Summary: The enrichment of geogenic phosphorus in groundwater systems is influenced by organic matter and Fe (oxyhydr)oxide. The reactivity of organic matter and Fe (oxyhydr)oxide determines the strategies of their coupled influence. Labile aliphatic organic matter coupled with the reductive dissolution of Fe (oxyhydr)oxide, while recalcitrant aromatic organic matter relies on Fe (oxyhydr)oxide as electron acceptors and conduits for degradation and methanogenesis. The main source of geogenic phosphorus is phosphorus-containing organic matter in one process and phosphorus associated with crystalline Fe (oxyhydr)oxide in the other. Geological setting also affects sediment deposition rate and subsequently influences the occurrence of geogenic phosphorus.
