Summary: A method for successfully grafting unsymmetrical A(2)BC-type 5,15-bis(4-butoxyphenyl)-10-(4-carboxyphenyl)-20-(phenanthrenoimidazolyl)-porphyrin onto the surface of nanostructured aluminum oxyhydroxide modified with a single SiO2 layer (NAOM) has been developed. This method allows for the preparation of a new porphyrin-containing hybrid material through a straightforward surface modification procedure of NAOM. The 3D heterostructure obtained was extensively characterized using XPS, TEM, and diffuse reflectance spectroscopy, and the stability of the material against leaching as well as the porphyrin immobilization ratio of approximately 14% by weight were revealed.

Summary: Cyclodextrins, known for their host-guest chemistry and low environmental impact, are widely used in pharmaceutical and food industries. However, their high solubility in water hampers their use for extraction purposes, which is being addressed through materials science research. Novel solid sorbents with cyclodextrins show promise for improved properties in pollutant adsorption. This systematic review highlights significant uses of cyclodextrins in adsorbing pollutants for both quantitation and remediation.

Summary: The study investigates the factors affecting ammonia synthesis in a dielectric barrier discharge reactor, using both experiments and a plasma kinetic model. The effects of plasma power, feed flow rate, N2:H2 feed ratio, gas residence time, temperature, and packing material were examined. The results show that increasing the feed flow rate and gas temperature with a packing material present in the plasma can enhance the ammonia synthesis rate.

Summary: Plasma-based nitrogen fixation is a promising alternative for fertilizer production, but factors like energy consumption and selectivity towards desired products hinder its applicability. This study investigated the use of rotating gliding arc plasma under elevated pressures, different gas flow rates, and composition, showing a significant increase in NOx production with low energy consumption (1.8 MJ/(mol N)), high production rate (69 g/h), and high selectivity (94%). This improvement is attributed to the enhanced thermal Zeldovich mechanism and increased NO oxidation rate due to elevated pressure.

Summary: We propose a zero-dimensional kinetic model to study the gas-phase dynamics of methane conversion in a nanosecond pulsed discharge plasma reactor. The model accurately captures the rapid changes in electric field, gas and electron temperature, and species densities. By validating against experimental data, we investigate the effects of gas temperature and reactor pressure on gas conversion and product selectivity. Furthermore, we analyze the important reaction pathways and the dynamics of the heating and cooling mechanisms. H radicals are identified as the most abundant plasma species, participating in hydrogenation and dehydrogenation reactions that mainly lead to the formation of C2H4 and C2H2 as products (depending on the pressure).

Summary: The effect of pore size on plasma catalysis is still unknown. In this study, 3D porous Cu and CuO with different pore sizes were prepared and compared in plasma-catalytic dry reforming. It was found that smaller pores led to higher conversion rates of CH4 and CO2, which provides valuable references for future research on plasma catalysts.

Summary: The performance of dielectric barrier discharge (DBD) plasma reactors in environmental and energy processes is limited due to their low energy yield. In this study, stainless steel rings were placed on the inner electrode rod of the DBD reactor to change the discharge gap and electric field, resulting in improved dry reforming performance. At 50 W supplied power, the rings negatively impacted the performance due to non-uniform discharge distribution. However, at 30 W supplied power, the rings improved the performance, and more rings with a larger diameter further enhanced it. The presence of rings increased the local electric field, displaced charge, discharge fraction, stability, and selectivity to syngas.

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: Live-cell imaging with fluorescence microscopy is a powerful tool in cancer research but can result in phototoxicity, causing disruption of redox balance and an overload of reactive oxygen species. We investigated the impact of phototoxicity on cellular homeostasis and response to non-thermal plasma (NTP), revealing increased sensitivity to NTP in cells used for live-cell imaging, likely due to altered proliferation rates and ROS levels. These findings have important implications for research using this technique and evaluating redox-based therapies.

Summary: This study developed a 2D axisymmetric model to investigate the influence of the two cathode emission mechanisms on the cathode region and the positive column in a plasma discharge in flowing nitrogen gas. The results show that the electron emission mechanism greatly affects the size and temperature of the cathode region, but has no significant impact on the discharge column at atmospheric pressure. Additionally, it was found that the discharge contraction is enhanced with increasing flow velocity due to increased convective heat loss.

Summary: Various strategies have been developed to cope with aspect ratio dependent etching (ARDE) in chip manufacturing, but they have their own limitations. In this study, we investigated the neutral transport mechanisms in ARDE by conducting experiments and simulations. Our findings suggest that the underlying mechanisms of ARDE involve shadowing and diffuse reflection of neutrals. We also explored different methods to regulate ARDE, with promising results obtained by adjusting the initial hardmask sidewall angle.

Summary: The current global energy crisis emphasizes the importance of understanding nonfossil fuel nitrogen fixation pathways for synthetic fertilizer production. This study investigates NH3 gas phase formation from humid N2 and air, demonstrating that adding water vapor increases nitrogen fixation capacity. However, a significant loss mechanism was identified, where HNO2 reacts with NH3 to form NH4NO2, which rapidly decomposes. Approaches to prevent this loss mechanism are discussed, such as in-line removal of HNO2 or direct solvation in liquid.

Summary: In this study, we evaluated new electrode configurations in a gliding arc plasmatron (GAP) reactor for CO2 conversion. The reactor design had limited influence on performance, with only slightly higher CO2 conversion compared to the basic GAP reactor design. Surprisingly, we found that different plasma reactors operating at atmospheric pressure showed similar performance, indicating potential performance limits. Further improvements should focus on aspects such as the post-plasma region to maximize the industrial potential of warm plasma technology.
