Summary: Novel carbon nanostructures, carbon nanobuds and nanoballs, have been successfully synthesized on the surface of graphene using the electrochemical method. Under a certain potential, carbon nanobuds are grown in situ on the surface of graphene, and with the increase of potential, these nanobuds grow into nanoballs and exfoliate from the graphene surface. Graphene undergoes oxidation at higher potentials, resulting in the formation of graphene oxide fragments.

Summary: A new strategy combining NH2-Ce-MOF with graphene oxide (GO) was developed to improve the anti-corrosion performance of epoxy coatings. The 2.0 wt% GO-Ce-MOF/EP composite significantly enhanced the anti-corrosion performance of the coating, attributed to the physical barrier provided by GO and the better compatibility achieved by modification of GO.

Summary: We have successfully grown high-quality WS2 and WSe2 nanotubes on Si substrates using catalytic chemical vapour deposition with Au nanoparticles. The Au nanoparticles act as nucleation sites for the growth of WS2 or WSe2 shells, which subsequently seed the growth of nanotubes. We find that the growth mode of nanotubes is sensitive to temperature and have achieved around 79% WS2 nanotubes with single chiral angles, primarily at 30 degrees (approximately 37%) and 0 degrees (approximately 12%). Furthermore, we demonstrate the tunability of geometric, electronic, and optical properties of WS2 nanotubes through their chirality.

Summary: The properties of carbon nanotubes (CNT) and the depth of the interphase are crucial factors that determine the interphase conductivity in polymer CNT nanocomposites (PCNT). The model proposed in this work takes into account the impact of CNT length, volume portion, and interphase density on conductivity, with the ability to substitute traditional models due to the inclusion of innovative terms related to nanocomposites.

Summary: Mercury exposure is a global public health problem, primarily through fish consumption and dental amalgam. Methylmercury has been shown to impact cardiovascular and metabolic health in highly exposed populations. Our study found that elemental mercury may influence LDL concentrations in adults with low-level exposure.

Summary: A series of polybenzoxazine/graphene composite foams with high EMI shielding effectiveness have been developed using a simple sol-gel method. Increasing graphene loading can reduce the density, form an electrically conductive path, and significantly enhance the electric conductivity and EMI SE of the composite foams. The EMI shielding is primarily achieved through absorption attenuation, with the composite foam showing absorption ratio higher than 98% in a specific frequency range due to multiple internal reflection and absorption.

Summary: Fluorination can significantly alter the physical and chemical properties of carbon materials. The concentration of edge C-F groups in multidimensional carbon materials depends on the crystallinity of the starting materials, fluorination pressure, and temperature, leading to significant differences in properties between different fluorinated structures.

Summary: In this study, serum peptidome analysis among CNT/F workers identified 41 highly discriminatory peptides that were strongly correlated with CNT/F exposure. The findings suggest that CNT/F exposure may lead to cardiovascular pathology and a pro-thrombotic state among exposed workers.

Summary: This research developed a novel method to synthesize a high-performance nanocomposite coating on PET fabric to enhance its UV-protection. The in-situ synthesis of rGO-Ag multilayer nanocomposite was achieved through direct redox reaction between Ag+ ions and GO sheets using ultrasonic and thermal treatment. The synthesized AgNPs with average size less than 100 nm were loaded on PET fabric, providing a significantly higher UV protection factor (UPF) of 6145.66 compared to uncoated PET fabric (UPF 33.63). Furthermore, the final fabric showed good air permeability and antibacterial properties due to the coating of rGO-Ag nanocomposite.

Summary: The study focuses on the microwave dielectric heating of graphite oxide during the synthesis of Nylon-6/GrO hybrid polymeric nanocomposites using different microwave input powers and two GrO morphologies. Results indicate that the morphology of GrO plays a determining role in its dielectric heating behavior, affecting the exfoliation and hybridization processes in the synthesis of HPNCs.
