Summary: This paper investigates the adsorption regularities and mechanisms of nonradioactive Cs(I) and Sr(II) analogs on bentonites with different chemical and mineral composition. The main mechanism is ion exchange, leading to the formation of outer-sphere complexes and, at higher pH values, inner-sphere complexes. Bentonite T exhibits higher adsorption capacity compared to other bentonites.

Summary: Q235b carbon steel, the main material of early alkaline radioactive liquid waste tank, can be contaminated by Sr-90 and Cs-137. Batch contamination experiments were conducted to simulate steel contamination, and the results showed that the main corrosion product Fe3O4 fell off and formed sludges. The study also found that Sr existed mainly as SrCO3 in the oxide layer and sludge, while Cs was mainly limited to the surface, in the form of CsNO3 on the surface of oxide layer and sludge. These findings will contribute to the development of efficient decontamination techniques.

Summary: The effect of MX-80 bentonite colloids on radionuclide sorption was investigated using batch and flow transport methods. A granitic drill core column and Sr(II) as a radionuclide were employed. Batch-type sorption and desorption experiments were conducted to determine the distribution coefficients of Sr(II) on bentonite colloids and metatexitic gneiss. Molecular modeling was used to assess the sorption affinity of the radionuclide and explain the differences in Sr(II) sorption behavior on biotite and montmorillonite. The distribution coefficients for colloids were found to be a hundred times higher than for granitic rock. Strontium breakthrough from the column with bentonite colloids was successfully achieved without significant retardation on rock minerals.

Summary: By modifying the ion-exchange affinity of nano-Hydroxyapatite (Ca-5(PO4)(3)OH, HAP) surface, we achieved rapid and selective adsorption of Sr-90 from groundwater. The modified HAP, Mg-HAP, showed the highest removal efficiency for Sr2+, attributed to the higher ion-exchange affinity of substituted Mg2+. The proposed modification method can improve the deployment of an in situ remediation technology for Sr-90 contaminated groundwater.

Summary: This study utilizes waste plastic pyrolysis residue as a carbon source and develops a sulfur host material for lithium-sulfur batteries to limit the shuttle effect. The residue is modified through annealing and thermal treatment, resulting in increased mesoporosity and the introduction of N-defects. Additionally, titanium sub-dioxide impurities are formed to effectively suppress diffusion of intermediates. The prepared carbon material contributes to retarding the decay rate of discharge capacity, with a decay rate of only 0.089% per cycle after 500 cycles.

Summary: This review focuses on the application of metal-free heteroatom-doped carbon catalysts in the electrochemical synthesis of hydrogen peroxide through the two-electron oxygen reduction reaction (2e(-) ORR). The electronic properties of carbon can be changed depending on the type of heteroatoms, which significantly affect the ORR catalytic activity. The location of active catalytic sites within the carbon network and the reaction environment, such as pH and electrolyte additives, are also investigated. This review provides fundamental insights into how heteroatoms enhance the electrocatalytic activity of metal-free carbon materials for the 2e(-) ORR.

Summary: We designed a membraneless potassium bromide electrochemical capacitor (ML-PBEC) single cell that generates high energy density and reduces self-discharge. Highly porous carbon with a hierarchical structure was synthesized from CO2 gas, and the effect of nitrogen doping on the CO2-derived carbon materials' electrochemical performance was investigated. The ML-PBEC single cell, using the synthesized carbon as electrodes and a Br-/Br3- redox active aqueous electrolyte, achieved enhanced energy density by suppressing the cross-diffusion of soluble bromine molecules through electrostatic interaction between N-doped sites' protons and polybromide anions even without a membrane.

Summary: This study explored the impact of dual impeller geometry on droplet size in the S-PVC polymerization process. A borescope method was used to measure droplet size in a biphasic liquid system, and it was found that replacing the upper paddle impeller with a 20-degree pitched paddle increased the Sauter mean diameter by 46.5%. The Sauter mean diameter also increased with larger impeller diameter and blade width. A revised geometrical factor (F) was considered, and a calculated maximum energy dissipation rate was used to establish a correlation for the Sauter mean diameter.

Summary: Chemical looping steam methane reforming (CL-SMR) can produce high-purity hydrogen without additional separation units. The reactivity of LaFeO3 oxygen carrier towards methane can be enhanced by introducing a small amount of iridium. Both particle reduction and oxidation were significantly improved by the presence of iridium, and the preparation pathways of oxygen carriers greatly affected the long-term performance. Although surface iridium species prepared by an impregnation method were severely aggregated during successive redox cycling, B-site incorporation of iridium led to the exsolution of IrOx nanoparticles anchored on the perovskite host and enhanced redox stability, which is essential for the long-term operation of the chemical looping process.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
