Stabilization-based remediation technology is a promising approach, and Fe⁰-modified biochar exhibits strong immobilization performance. In this study, nano zero-valent iron (nZVI) was synthesized via the liquid-phase reduction method and loaded onto corn straw biochar prepared at 300°C and 600°C (MSB300 and MSB600) to form composite adsorbents (nZVI@MSB300 and nZVI@MSB600). The adsorption behavior of Cd(II) on loess soil (Ls) and 1:9 (w/w) biochar–soil mixtures (nZVI@MSB300-Ls and nZVI@MSB600-Ls) was investigated by batch experiments. The effects of contact time, initial Cd(II) concentration, and solution pH on the adsorption behavior were tested. Kinetics, isotherms, and material characterization were investigated to elucidate the sorption performance and mechanisms. The maximum adsorption capacities of Ls, nZVI@MSB300-Ls, and nZVI@MSB600-Ls for Cd(Ⅱ) were 6.3, 9.8, and 13.0 mg/g, respectively, with nZVI@MSB600-Ls exhibiting the highest performance. The adsorption kinetics conformed to the pseudo-second-order model (<em>R</em>²≥0.91), and the adsorption isotherms fitted the Langmuir model (<em>R</em>²≥0.95), indicating a chemisorption-dominated mechanism. Post-adsorption characterization using Scanning electron microscope-Energy dispersive spectrometer (SEM–EDS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction spectroscopy (XRD), and X-ray photoelectron spectroscopy (XPS) revealed that nZVI@MSB300 and nZVI@MSB600 mainly immobilized Cd(II) through complexation, cation exchange, cation–π interactions, and precipitation, whereas loess primarily relied on complexation and precipitation.

Inspired by the structure of natural cartilage and based on our previous research, we developed a new type of porous UHMWPE-based artificial joint material doped with copper-containing carbon dots (Cu-CDs). In a protein-containing lubricating medium, this material exhibited auto-antifriction properties by absorbing/releasing the lubricating medium and forming a protein film on the tribo-interface. These effects can significantly enhance the wear resistance of UHMWPE. The results showed that spherical Cu-CDs with an average size of 5–6 nm were successfully prepared. The tensile strength of the porous UHMWPE doped with Cu-CDs (Cu-CDs@UHMWPE) (approximately 9.93 MPa) was close to that of natural joint cartilage. Cu-CDs@UHMWPE promoted the adsorption of proteins by the friction interface and formed a protein film that reduced wear. Under the same friction conditions, the wear index of Cu-CDs@UHMWPE was approximately three times lower than that of pure UHMWPE.

Although carbon dots (CDs) have been widely explored as defect passivators, their capability to regulate perovskite phase stability has rarely been explored. In this study, we report highly crystalline carbon dots enriched with amino, carboxyl, and hydroxyl groups as a dual-function interfacial modifier at the SnO₂/perovskite buried interface. Distinct from conventional amorphous CDs, the high crystallinity of these CDs enables enhanced defect-passivation capability and improved ability to suppress harmful phase transitions, thereby simultaneously passivating Pb²⁺-related defects and suppressing the detrimental α-to-δ phase transition during device operation. The multifunctional surface groups coordinate with undercoordinated Pb²⁺ and I⁻, thereby effectively inhibiting the formation of PbI₂ and the phase degradation of perovskites. Consequently, the CDs-modified perovskite films exhibit improved crystallinity, enlarged grain sizes, suppressed interfacial non-radiative recombination and enhanced interfacial charge extraction. The optimized PSCs deliver a champion power conversion efficiency of 21.50 % and retain 83 % of their initial efficiency after 1000 h of continuous illumination, significantly outperforming the control devices, which retain only 43 %.
