Summary: Ce-modified MnO2 was successfully synthesized using a simple and inexpensive redox method. The catalyst calcined at 400 degrees Celsius showed the best catalytic activity in the total oxidation of HCHO with a temperature of 50 degrees Celsius for 50% conversion of HCHO to CO2. The calcination step at 400 degrees Celsius enhanced the Ce-O-Mn surface interactions and the presence of Ce4+/3+ species, resulting in high activity in HCHO oxidation.

Summary: In this study, plasma treatments were applied to PLA and PLA/PAni solutions prior to electrospinning, improving their viscosity and conductivity, and resulting in uniform and well-elongated nanofibers. The nanofibers were further treated with a dielectric barrier discharge (DBD) treatment, which significantly increased their surface wettability. The presence of conducting PAni in the scaffolds further promoted the behavior of PC-12 cells, leading to an increase in neurite density.

Summary: Plasma-catalysis is considered as a promising method for decomposing hazardous VOCs, and extensive experimental and modeling studies have been conducted to understand its fundamental mechanisms. However, there is a lack of literature on summarized modeling methodologies. This short review provides a comprehensive overview of modeling methodologies in plasma-catalysis, classifies and summarizes the modeling methods of VOCs decomposition, critically examines the roles of plasma and plasma-catalyst interactions, and offers perspectives for future research directions. The aim of this review is to stimulate the further development of plasma-catalysis for VOCs decomposition with advanced modeling methods in both fundamental studies and practical applications.

Summary: This study investigates the influence of pore characteristics on microdischarge plasma inside pores of catalysts through numerical simulations. The results show that the distribution of electron density, electron temperature, and electric field in and near a pore is significantly affected by adjacent pores. Smaller pore size and higher applied voltage lead to stronger interactions between pores. This research is important for understanding plasma catalysis mechanisms, particularly the influence of pore interactions on microdischarge in porous catalysts.

Summary: Cu (10 wt%) materials were prepared on silica nanotubes via two synthetic approaches, co-synthesis and wetness impregnation. The Cu-based silica nanotubes showed the best performance in toluene oxidation, with a lower T-50 (306 °C) compared to the reference catalyst (345 °C). The excellent catalytic properties were attributed to the finely dispersed copper (II) species on the surface of silica nanotubes.

Summary: Covalent triazine frameworks (CTFs) based on polydentate ligands are promising catalyst supports that combine the reactivity of homogeneous catalysts with the robustness and recyclability of heterogeneous ones. In this study, a rhodium (III) complex was immobilized on a bipyridine-based CTF for the transfer hydrogenation of N-heteroarenes in water using sodium formate as the hydrogen source. The immobilized catalyst showed excellent activity for various quinoxalines and other N-heteroarenes, and maintained high activity during recycling, making it suitable for continuous flow synthesis.

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.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
