Summary: The study presents experimental evidence of electronic and optical interlayer resonances in graphene van der Waals heterostructure interfaces. Using spectroscopic mode of a low-energy electron microscope (LEEM) and Raman spectroscopy, researchers found an increase in the interlayer spacing of 30 degrees twisted bilayer graphene and observed a unique type of Fano resonance around the D and G modes of the graphene lattice vibrations. This robust Fano resonance is a direct result of quantum confinement and the interplay between discrete phonon states and the excitonic continuum.

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: This study presents a combined experimental and theoretical analysis of the degradation of nitrogen-doped multi-walled carbon nanotubes by human myeloperoxidase in vitro. The degradation process leads to the removal of smaller diameter CNTs and the formation of highly deformed NMWCNTs decorated with NaCl nanoparticles. Density functional theory calculations reveal the reactivity of carbon walls around nitrogen-doped sites, leading to the presence of hypochlorite species and physisorbed HClO molecules.

Summary: Plastic-contaminated drinking water is a global concern, with a focus on microplastics contamination in a conventional water treatment plant in Thailand. The study found that the water treatment plant had an overall removal efficiency of 67.6% to 57.2%, with a substantial number of microplastics still present in the treated water. The dominant sources of microplastics contamination were identified as raw water and internal contamination within the plant, posing a challenge to drinking water quality in Thailand.

The performance of the WLED was further improved by optimizing the components and incorporating nitrogen-doped graphene quantum dots (NGQD).

Summary: Carbon nanotubes have been widely studied in various scientific and technological fields due to their unique properties. However, their toxic nature limits their potential applications in biomedicine. In this study, we synthesized paramagnetic CNT/Gd2O3 hybrid nanostructures through a scalable electrochemical deposition technique. The nanostructures exhibited significant longitudinal relaxivity for water protons, suggesting their potential use as MRI contrast agents. In vitro cytotoxicity tests on normal and cancerous cells demonstrated that the CNT/Gd2O3 hybrid nanostructures were more biocompatible compared to pure CNTs, which was further supported by theoretical studies using MD simulations.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
