Summary: In this work, we introduce an experimental protocol to engineer nanometer scale pores in CVD graphene membranes under ambient conditions, using low power ultra-short laser pulses and overcoming the drawbacks of other perforation techniques. We visualized and quantified the nanopore network using Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM), while Raman spectroscopy is utilized to correlate the nano-perforated area with the nanotopographic imaging. Our results suggest that Raman imaging provides the identification of nanoporous area and, in combination with AFM, we provide solid evidence for the reproducibility of the method, as nanopores of a certain size distribution are formed under these experimental conditions.

Summary: This article focuses on the fabrication of a thin film of reduced graphene oxide (rGO) through pulsed UV laser irradiation. The study found that the laser power energy has an influence on the thickness, carbon content, oxygen content, electrical resistance, and specific surface area of the fabricated thin film. Laser irradiation leads to the reduction of oxygen and the restoration of sp2 hybridization, resulting in a material with reduced electrical resistance and improved specific surface area. Under specific conditions, a thin film with good electrical conductivity can be obtained.

Summary: This study investigated the association between child toxicant exposure and growth and development, finding that arsenic, lead, and mercury concentrations in children's nails were associated with lower child development scores. However, the negative association between mercury and neurological development was attenuated with increasing selenium concentration. Therefore, selenium status should be considered when assessing the impact of heavy metal toxicants on neurodevelopmental outcomes in children.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
