... Presently, ICRFBs have garnered considerable attention owing to their notable advantages. Unlike the highly toxic bromine and V 5+ , the environmentally friendly redox-active species of iron and chromium are employed in ICRFBs [23]. Moreover, the redox-active species for ICRFBs can be readily obtained by dissolving chromium and iron chloride in hydrochloric acid, contributing to their cost-effectiveness, estimated to be as low as $12/kWh [24]. ...

... 32 Previous studies have confirmed that certain congeners, such as UV-P, UV-327, and UV-328, can be metabolized by human cytochrome P450 enzymes. 36 Notably, CYP3A4 has been reported to be responsible for the metabolism of UV-328, demonstrating its role in the metabolic activation of this compound. 37 To explore this possibility, we employed ADMETlab 2.0 38 to assess the likelihood of UVs acting as substrates and inhibitors for these enzymes. ...

... Air cooling, the earliest developed and simplest thermal management method, remains the most mature [22]; however, for large marine batteries, the cooling effect cannot be achieved. Especially in the liquid flow cooling technology, as an efficient thermal management method, its position in the simulation research on the thermal management of power battery packs is increasingly prominent [23,24]. The main advantages of using liquid as a heat transfer medium are high heat transfer capacity and fast cooling and heating. ...

... The wide presence of chlorinated paraffins in children's toys and other products that children come in contact with regularly is particularly troubling given that these chemicals are known to leach out of products (Dong et al. 2020, Wong et al. 2017, Lucattini et al. 2018, Weng et al. 2023. This means that children playing with plastic toys may be exposed to increased levels of chlorinated paraffins due to accumulations of the leached chemicals in dust, leaching upon skin contact (dermal uptake), hand-to-mouth behaviors, and through chewing on the toys (oral exposure). ...

... The redox reactions involving Mn 3+ /Mn 2+ typically occur in highly acidic environments (pH < 1), exhibiting a high potential (1.51 V vs SHE) and high solubility, which are advantageous for the development of MFBs with elevated energy density. Nevertheless, Mn 3+ is susceptible to instability in aqueous solutions, leading to spontaneous disproportionation reactions that yield Mn 2+ and MnO 2 , ultimately resulting in diminished low coulombic efficiency (CE) of the battery [27]. Concurrently, the presence of residual non-conductive MnO 2 leads to passivation of the electrode surface, obstruction of flow paths, elevation of battery polarization, and deterioration of capacity. ...

... The diversity of pesticides used in agriculture has naturally resulted in a multitude of TPs, as each PPP may degrade into several distinct TPs. Despite recent regulatory efforts to restrict certain PPPs, advancements in analytical techniques have enabled the reliable detection of various TPs in environmental matrices (Martínez Vidal et al. 2009;Dufour et al. 2021;Huang et al. 2023), revealing a wide variety of TPs in the environment (Le Ulrich et al. 2022). By undergoing multiple transformation processes, PPPs degrade into more polar substances, resulting in increased mobility and persistence in the environment, as observed with TPs from atrazine (Belfroid et al. 1998;Fenner et al. 2013). ...

... In a separate investigation, the utilization of Fe 3+ /Fe 2+ as a redox mediator is implemented in the catholyte of a Ti-Mn flow battery in order to enhance the efficiency of the MnO 2 /Mn 2+ pair with a 1MnSO 4 -1.5TiOSO 4 -3H 2 SO 4 electrolyte ( figure 5(d)) [61]. The reduction peak potential of Fe 3+ /Fe 2+ is found to be lower than that of MnO 2 /Mn 2+ and higher than the oxidation peak potential of TiO 2+ /Ti 3+ . ...

... UV filters can also be used in various types of cosmetics, personal care products, and even in industrial products, including food packaging, containers, and printing inks, which require UV protection (Bradley et al., 2013;de Miranda et al., 2021;Molins-Delgado et al., 2017). UV filters were therefore detected in various human matrices, including urine (Bury et al., 2023), serum (Frederiksen et al., 2021), cord blood (Sunyer-Caldú et al., 2023), placental tissue (Valle-Sistac et al., 2016), and breast milk (Liu et al., 2022). Indeed, following the dermal application of sunscreens, a randomized clinical trial study demonstrated that the active ingredients of commercial sunscreens, i.e., butyl methoxydibenzoylmethane (BMDBM), benzophenone-3 (BP3), 2-ethylhexyl salicylate (EHS), and EHMC, homosalate (HS), octocrylene (OCT), terephthalyidene dicamphor sulfonic acid (TDSA), could be absorbed into systemic circulation and remained at levels that warrant caution for several days even after the cessation of the application (Matta et al., 2019;U.S. FDA, 2016). ...

... Except for the four hydrocarbons C 7 H 14 , C 9 H 14 , C 9 H 16 , and C 11 H 12 , all of these IVOCs have been reported to degas from asphalt pavements at 60°C . So far, only C 14 H 18 has been reported as a fresh gas-phase emission (transport time < 2.5 min), originating from a farm (Loubet et al., 2022) in ambient air, while C 17 H 28 has been observed in the aerosol phase (Xu et al., 2022). The road construction factor also accounts for the largest percentage share of a long list of OVOCs: C6 diketone isomers (C 6 H 10 O 2 ); C 2 -substituted phenol (C 8 H 10 O); C 7 H 12 O 2 ; C 8 H 14 O 2 ; C 8 H 16 O 2 ; phthalic anhydride (C 8 H 4 O 3 ), which is a naphthalene oxidation product (Bruns et al., 2017); C 9 H 10 O; , indicating that most OVOCs in this factor are possibly oxidation products of short-lived IVOC hydrocarbons emitted by this source. ...

... In order to adapt to the harsh operating parameters of ICRFB and lower the cost of Nafion membranes, Ma et al. selected lowcost commercial porous polyethylene film as the skeleton, and filled the pores with Nafion resins to obtain the composite membranes with high thermal, chemical, and mechanical stability (Qiao et al. 2022b). The composite membranes showed high ion selectivity, chemical stability, proton conductivity, and nearly no swelling when operated at elevated operating temperature. ...
