“…Figure S14 shows the individual FTIR spectra for the technical-grade PFAS standard and quartz sand (550 to 1550 cm –1 ). The characteristic vibrational modes for PFSAs and quartz sand were assigned based on literature values − (see the Supporting Information). Figure S15 shows the FTIR spectra of spiked quartz sand at 0 and 600 min milling time.…”

Perfluorosulfonic acids (PFSAs) are a recalcitrant subclass of per-and polyfluoroalkyl substances (PFASs) linked to numerous negative health effects in humans. Scalable technologies that effectively destroy PFSAs will greatly reduce the future health and ecological impact of these "forever chemicals". Herein, we show that several PFSAs undergo facile mechanochemical destruction (MCD) in the presence of quartz sand (SiO 2 ). This process operates in the absence of solvent, at ambient temperature and pressure, generating a benign solid byproduct. Quantitative analysis of milled samples revealed high destruction efficiencies of 99.95% to 100% for five different PFSAs subjected to MCD conditions in the presence of SiO 2 only. Extensive nontargeted analysis showed that, during degradation, other PFASs form and are ultimately destroyed upon extended mechanochemical treatment. Direct polarization (DP) and cross-polarization (CP) solid-state nuclear magnetic resonance (SSNMR) spectroscopy showed abundant silicon−fluorine (Si−F) bond formation post-MCD, indicating that fluorine was secured in a stable reservoir. Collectively, these results identified the degradation profile for an environmentally sound and effective PFSA degradation process that is amenable to scale-up.

“…For example, high amination and sulfonation can make them potential candidates in different applications, such as dispersants, carbon dioxide absorbents, gas separation membranes and proton exchange membranes. 100 In order to reduce the human dependence on fossil fuels, biomass-derived fillers have been developed as a substitute for carbon black in the rubber industry. After adding rubber, the lignin-silica hybrid material significantly improves the tensile strength, tear strength and abrasion resistance of rubber compared with carbon black.…”

“…[5] Fe-mediated Fenton reaction occurs according to the typical reactions as follows: [6] In addition to Fe(II), Cu(II), Mn(II), or Ti(II) can also act as CDT agents to catalyze Fenton-like reaction, thus producing •OH to damage cancer cells. [7] Although much attention has been paid to utilizing the catalytic ability of metal ions to treat tumors, the administration of metal ions alone cannot obtain satisfactory treatment effect due to their insufficient tumor accumulation. [8] Encouragingly, the combination of metal ions with nanoparticles (NPs) may promote the tumoral delivery of metal ions to facilitate efficient CDT.…”

To realize precise tumor treatment, chemodynamic therapy (CDT) that utilizes metal element to trigger Fenton or Fenton‐like reaction to generate cytotoxic hydroxyl radicals in tumor region has been widely investigated. Recently, the dendrimers featured with abundant surface functional groups and excellent biocompatibility are regarded as promising carriers of metal elements for tumor delivery. Much effort has been devoted to design dendrimer‐based nanodrugs for CDT and CDT‐involved synergistic therapy of tumors. Herein, the recent advances in the construction of dendrimer‐based nanodrugs (in most cases, poly(amidoamine) dendrimers) for CDT, CDT/chemotherapy, CDT/phototherapy, CDT/gene therapy, or CDT‐involved multimodal therapy are reviewed. Furthermore, the future perspectives with regard to the development of dendrimer‐based nanodrugs for CDT‐involved tumor treatment are also briefly discussed.
