Summary: In this study, a melamine sponge composite called SA/CMC-MeS was prepared through crosslinking strategy, which showed enhanced adsorption performance for methylene blue (MB). The adsorption process of SA/CMC-MeS followed the Langmuir model and pseudo-second-order kinetic model, with a theoretical maximum adsorption capacity of 230 mg/g (pH 8). The adsorption mechanism was attributed to the electrostatic attraction between the carboxyl anions on the composite and the dye cations in solution. SA/CMC-MeS could selectively separate MB from binary dye system and had positive anti-interference ability in the face of coexisting cations.

Summary: Water contamination is an increasing problem due to the versatile applications of heavy metal ions, but the selective removal of these ions from wastewater remains an issue. To address this, a ZnO-PVA-coated membrane was developed using a sol-gel process and bio-inspired Azadirachta indica (neem) extract. The membrane successfully removed Pb+2 ions from polluted water solution, with a removal efficiency of 93.99% at pH=4 and a maximum adsorption capacity of 218.47 mg/g.

Summary: A new lanthanum sulfide nanoparticle was synthesized and incorporated onto magnetic graphene oxide sheets to create a potential adsorbent for efficient removal of lead ions from wastewater. The synthesized adsorbent was characterized and parameters such as pH, dosage, contact time, concentration, and temperature were studied. The Langmuir isotherm model showed the best fit with a maximum adsorption capacity of 123.46 mg/g, indicating a monolayer adsorption pattern. The pseudo-second-order kinetic model best described the adsorption rate, while the thermodynamic model suggested a chemisorption and physisorption adsorption mechanism at different temperatures.

Summary: An activated carbon-geopolymer composite (ACGC) was synthesized using fly ash to treat Pb(II) contaminants in wastewater and soil. The composite showed improved adsorption capacity and stabilization performance due to the synergistic effect between the geopolymer matrix and activated carbon. The 40ACGC sample, which contained 20 wt% activated carbon, exhibited the highest adsorption capacity for Pb(II) and followed a pseudo-second-order adsorption kinetics. The study suggests that geopolymer-based materials offer a promising approach for remediating heavy metal-polluted soil.

Summary: Efficient C-13 hyperpolarization of ketoisocaproate was achieved using SABRE-SHEATH. By undergoing simultaneous chemical exchange with an Ir-IMes-based complex, parahydrogen atoms transferred their polarization to the C-13 nucleus of ketoisocaproate, resulting in high polarization values. The polarization build-up was possible due to favorable relaxation dynamics. Evaluation: 8 points.

Summary: A series of novel mixed metal oxides (MOs) were prepared as supports for Ni/MOs using the double hydrolysis technique. The desulfurization study showed that the 10%NiZnO-Al2O3 adsorbent exhibited superior desulfurization performance with a breakthrough point of 10 ppm in model gasoline. The superior desulfurization performance was attributed to its higher Lewis and Lewis/Bronsted acid site ratio, higher surface area, larger pore size distribution, and lesser amount of inactive ZnAl2O4 spinel.

Summary: Efficient hyperpolarization of [N-15(3)]metronidazole was achieved using the SABRE-SHEATH technique. The functionalization of [N-15(3)]metronidazole with a fluorine-19 moiety was also successful, resulting in efficient hyperpolarization of all three N-15 sites. The spin-relayed polarization transfer between N-15 and F-19 was found to be less efficient.

Summary: Conventional nuclear magnetic resonance (NMR) is used to detect chemical transformations by exciting and detecting the precessing spins of nuclear spin ensembles. In this study, we employ Radiofrequency Amplification by Stimulated Emission of Radiation (RASER) to detect chemical transformations without the need for external radio frequency pulses or background signals. We investigated the hydrolysis of hyperpolarized ethyl-[1-C-13]-acetate using both conventional NMR and C-13 RASER and observed a complete disappearance and delayed reappearance of the RASER signal without destroying the C-13 polarization.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
