Summary: The study introduces a facile strategy for fabricating Nd3+-doped rare-earth core-shell nanoparticles (Nd-RENPs) with strong emission in the near-infrared-II (NIR-II) window. These Nd-RENPs can be quickly eliminated from the hepatobiliary pathway, reducing the potential risk of long-term retention in the reticuloendothelial system (RES). Additionally, the Nd-RENPs are successfully utilized for NIR-II in vivo imaging and magnetic resonance imaging (MRI) contrast agents, enabling precise detection of breast cancer.

Summary: Limited light absorption and low charge separation rate in graphitic carbon nitride (g-C3N4)-based photocatalyst are overcome by embedding onion-liked carbon (OLC) structures in the matrix. The highly hybridized and electrically conductive OLC broadens visible light absorption, narrows the band gap of g-C3N4, and promotes the separation of photo-generated carriers. The g-C3N4/OLC composites show significantly increased hydrogen evolution rate and efficient degradation of RhB, demonstrating the potential of OLC in designing carbon-based photocatalysts for solar energy conversion and pollutant degradation.

Summary: This paper investigates the friction and wear behaviors of two types of polycrystalline diamonds against different materials. The results show that increasing surface roughness leads to an increase in coefficient of friction. The coefficient of friction and wear rate of ceramic Si3N4 balls are generally lower than those of steel GCr15 balls, except for one type of polycrystalline diamond. Transfer films of SiO2 and its hydrate are observed at the friction interface, which contribute to smoother friction and wear. Carbon-based transfer films are also identified, mainly catalyzed by residual cobalt in the polycrystalline diamonds, leading to a phase transformation.

Summary: A single-beam Z-Scan experiment was conducted to investigate the nonlinear optical absorption and optical limiting properties of Bi2O3, rGO/Bi2O3, Bi2O3/WO3, and rGO/Bi2O3/WO3 nanostructures. The results showed that the synthesized nanostructures exhibited varying levels of nonlinear absorption, with bismuth-based nanostructures showing the lowest optical limiting threshold and a higher two-photon absorption coefficient. The presence of rGO contributed to the extended conjugation for charge transfer, while the strong UV-Visible absorption of Bi2O3 and WO3 led to a unique nonlinear optical response.

Summary: The recent observations of superconductive-ordering in carbon-based systems consisting of rhombohedral stacking-faults, trilayer graphene (ABC-stacks) or dislocation-rich interfaces (pyrolytic graphite) have attracted significant attention. In this study, an unusual nucleation of rhombohedral stacking-faults in low-dimensional systems comprising of multiwall carbon nanotube (CNT) buckypapers was reported. The presence of sulfur doping resulted in a broad-band at the Raman shift from 1800 to 2000 cm(-1), indicating contributions arising from disorder-rich regions with rhombohedral stacking-order (ABC-stacks). These observations were further supported by X-ray diffraction and Rietveld refinements.
