Summary: Glass-ceramics in the xBeO-20Fe2O3-(80-x)TeO2 system with x = 0-25 mol% were synthesized and studied. The addition of BeO supported the crystallization of Fe2O3 during melting, resulting in an increase in the crystalline Fe2O3 phase and crystallite size with higher BeO content. Samples doped with BeO exhibited enhanced polymerization of the residual tellurite glass network compared to undoped samples, and all synthesized materials showed spin-glass behavior. Additionally, the Morin transition of hematite at 260 K was observed, with the intensity depending on Fe2O3 content and correlating with the amount of added BeO.

Summary: A temperature dependent Raman spectromicroscopic study was conducted on multiwall carbon nanotubes to investigate anharmonic effects, revealing non-linear shifts in the peak position of Raman D- and G-bands with temperature. Phonon softening and hardening of Raman modes were observed over a wide temperature range, with the G-peak shift explained by anharmonic properties of the graphite lattice. The width variation of the G-peak appeared to be nearly independent of temperature due to competing effects from electron-phonon coupling and anharmonic contributions.

Summary: Recent progress in optical bioimaging has led to the demand for minimal chemical reporters that can preserve the properties and activities of biomolecules. Various approaches have been developed to reduce the size of fluorescent and Raman labels to a few atoms and incorporate them into building blocks to form native-like supramolecular structures. This integration of small optical reporters into biomolecules has enabled the creation of previously inaccessible smart molecular entities, greatly expanding their applications in biological imaging.

Summary: In this study, the researchers investigated the effects of phase and vertical structure of Molybdenum disulfide (MoS2) nanosheets on the activation of hydrogen peroxide (H2O2) in Fenton-like reactions. The results showed that the metallic 1 T phase of MoS2 favored the dark-Fenton-like reaction, while the biphase 1 T/2H MoS2 was beneficial for the photo-Fenton-like reaction. The vertical structure of MoS2 nanosheets was found to be more effective in promoting H2O2 activation compared to phase regulation. The study also proposed degradation pathways for tetracycline (TC) and demonstrated the stability and recyclability of the optimized MoS2-based catalysts. This work provides guidance for the design of highly efficient MoS2-based Fenton-like or photo-Fenton-like catalysts.

Summary: This study investigates the control of NO in marine ship exhaust and proposes a new method for NO2 removal based on hydrodynamic cavitation. The results show that hydrodynamic cavitation can delay but not prevent the production of NO, and the accumulation and decomposition of HNO2 are the primary causes of NO formation. Further experiments reveal that ClO2, H2O2, and Na2S2O8 can slightly increase the NO2 removal efficiency, while NaClO2 is less effective than water.

Summary: Different sizes of FeWO4 nanorods were synthesized by altering the pH of the precursor solution via a hydrothermal method. FeWO4 nanorods prepared at pH = 7 (FeWO4-7) were shorter than those prepared at pH = 2 (FeWO4-2). FeWO4-7 exhibited superior activity compared to FeWO4-2, with larger specific surface area, stronger visible-light-absorbing ability, and higher photogenerated charge separation and transfer efficiencies. The photo-Fenton catalytic and photocatalytic efficiencies of FeWO4-7 were about 8.5 and 2.9 times those of FeWO4-2, respectively. This study is important for the hydrothermal preparation of high-efficiency visible-light-active FeWO4 photo-Fenton catalyst and photocatalyst, and the pH-modulated microstructural control method may be applicable to synthesize semiconductor nanomaterials with varied microstructures.

Summary: This study explores the use of N-doped graphdiyne nanotubes (NGNTs) as a catalyst for metal-free PMS activation in water remediation. The NGNT-PMS system decomposes heterocyclic contaminants via electron-transfer-mediated nonradical oxidation, where metastable NGNT-PMS* complexes act as the primary oxidants. The NGNT-PMS system exhibits higher reaction rates compared to N-doped carbon nanotubes (NCNTs) and graphene oxide (NGO) systems, and also plays a crucial role in the cleavage of pyridine heterocycles and C-Cl bonds.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
