Summary: The use of ammonia as a storage medium for hydrogen and its plasma-catalytic decomposition for retrieval of hydrogen are investigated. Experimental results show that increasing the specific energy input enhances the ammonia conversion. A kinetic model is used to analyze the decomposition mechanism, indicating that the collisions between NH3 and high-energy electrons initiate the decomposition.

Summary: This study investigated the effects of different influencing factors (different power, different initial concentration of chlorpyrifos, different environmental components) on the degradation of chlorpyrifos in water, and explored the relevant mechanism of plasma for the degradation of chlorpyrifos. The experimental results showed that when the plasma power was 22.2 W and the treatment time was 10 minutes, 20 mg/L chlorpyrifos was almost completely degraded and its toxicity was greatly reduced. Cl- was found to effectively promote the degradation of chlorpyrifos, while CO32-, HCO3-, and HA inhibited its degradation. SO42- and NO3- had no obvious effect on the removal efficiency of chlorpyrifos. ESR and quenching experiments confirmed that & BULL;O2-, & BULL;OH, and 1O2 were effective reactive species in the degradation of chlorpyrifos, with & BULL;O2- having a more pronounced effect. The long-lived reactive species H2O2 and O3 also had a certain promoting effect in the degradation process.

Summary: Plasma-assisted catalytic decomposition of CO2 over CeO2 nanocatalysts with different morphologies (cube, rod, and hexagon) was investigated. Among them, CeO2 nanorods (CeO2-R) exhibited the highest CO2 conversion. The better performance of CO2 activation over CeO2-R was attributed to the abundant oxygen vacancies on its (110) crystal plane. The CO2 molecules adsorbed on oxygen vacancies over CeO2-R were partly activated and more easily decomposed in the plasma, resulting in higher CO2 conversion.

Summary: This study used experimental and numerical analyses to model and optimize the degradation and mineralization of the pesticide diazinon using non-thermal atmospheric pressure plasma. Factors such as the initial concentration of diazinon, pH of the medium, and flow rate of the plasma feeding gas were considered. It was found that the gas composition and flow rate had significant effects on the type and concentration of reactive nitrogen and oxygen species generated. The study also identified the importance of gas flow rate in total organic carbon (TOC) removal. The energy yield of the treatment procedure was high, suggesting the potential of plasma for treating diazinon-polluted water.

Summary: Antibiotics are widely used and their discharge into the environment poses a constant potential threat to the ecosystem. This study focused on the treatment of wastewater containing levofloxacin and sulfadiazine, two typical antibiotics, using atmospheric-pressure dielectric barrier discharge (DBD). The results showed that the total antibiotics removal efficiency could be improved compared to separate single antibiotic treatment. The role of plasma-induced reactive oxygen/nitrogen species (RONS) was examined, with hydroxyl radicals (OH) playing a major role in levofloxacin degradation and ozone and peroxynitrite also contributing to sulfadiazine degradation. The bio-toxicity evaluation demonstrated the safety of the DBD degradation products for the ecological environment.

Summary: Hydrogen as a secondary energy carrier has great potential in meeting renewable and sustainable energy demand. Recent developments in microplasmas have reduced the energy requirement of water plasmolysis to be on par with electrolysis. However, there is still room for improvement in the dissociation efficiency of water vapors. This study investigates the plasmolysis of water vapors with both empty channel plasma reactor and glass beads packed plasma reactor. The results show that the glass beads packed plasma micro-reactor achieved a hydrogen production rate of 23.9 g/kWh, significantly higher than previous studies.

Summary: In this study, the dielectric barrier discharge (DBD) low temperature plasma technology was used to degrade dimethyl hydrazine wastewater. Qualitative and quantitative methods were used to study the changes of NDMA and FDMH during the degradation process. The formation mechanisms of NDMA and FDMH were calculated using density functional theory and molecular orbital theory. Through the research, it was found that NDMA is produced by the oxidation of -NH2, while FDMH is mainly produced from dimethyl hydrazine and formaldehyde.

Summary: Initiated by incipient wetness impregnation, dispersed tin atoms were deposited on gamma-Al2O3. Various characterization techniques were used to analyze the morphology and structure of the catalysts, revealing isolated and well-dispersed Sn oxide sites at relatively high coverages. The study suggests that active catalytic sites during propane dehydrogenation involve Al2O3 rather than bulk sulfide and Sn atoms dispersed over alumina.

Summary: This study presents a real-world testing of a novel hybrid gas-to-particle conversion system for the removal of volatile organic compounds (VOCs) emitted from wood processing facilities. The system utilizes plasmolysis/ozonolysis, photolysis, nucleation, coagulation and agglomeration of aerosols, and precipitation of agglomerates in an electrostatic field to achieve efficient VOC removal. The results show a VOC removal efficiency of 92.8%, with 100% removal efficiency for specific VOCs. The gas-phase advanced oxidation system demonstrates competitive performance in treating VOC polluted flue gases with relatively low energy input.

Summary: Polycaprolactone (PCL) is a suitable material for cartilage tissue engineering due to its mechanical strength, low immunogenicity, elasticity, and biodegradability. Enhancing the hydrophilicity of PCL scaffolds is necessary, and in this study, ozone treatment and TGF beta 3 loading were used to improve the properties of electrospun bilayer PCL scaffolds. In vitro and in vivo evaluations showed that the ozone-treated scaffold loaded with TGF beta 3 and rMDSCs demonstrated better chondrogenic potential and cartilage regeneration outcomes.

Summary: Ammonium carbonates, including ammonium bicarbonate, ammonium carbonate hydrate, and ammonium carbamate, were once extensively used as fertilizer materials but gradually replaced by urea fertilizers. With the emergence of sustainable agriculture, there is a need to recover and reuse nutrients using conventional feedstocks and biogenic waste streams. Anaerobic digestion liquid presents a convenient source to produce solid fertilizers containing nitrogen and carbon. This review discusses the feedstocks, methods to concentrate and crystallize solid ammonium carbonates, technologies to stabilize them in the environment, and their agricultural efficiency as nitrogen and carbon sources.

The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
