Complementary devices with double-hybrid electrodes are prepared, assembled, and studied to improve the performance of complementary devices and take advantage of the excellent performance of composite electrochromic films. WO 3 films are prepared through the seed-assisted hydrothermal method, and polyaniline (PANI) is coated on WO 3 via electrochemical deposition. The electrochemical and electrochromic properties of the WO 3 /PANI composite films are better than those of WO 3 films. The improvement in the electrochromic properties of the WO 3 /PANI composite films is mainly due to PANI’s modification of the surface morphology of the WO 3 films and its excellent conductivity. Then, a complementary device with a double-hybrid electrode is assembled. The WO 3 /PANI and NiO/PB electrode films are used as the cathode and anode of the device, respectively, and KCl solution is employed as the electrolyte. The light modulation range of the complementary device is 55.71%, the coloring time is t c = 3.2 s, the bleached time is t b = 8.1 s, and the coloring efficiency is 24.63 cm 2 ·C −1 . All of these values are better than those of the single WO 3 and NiO devices. The electrode reaction process of the complementary device is synchronous and synergetic. Thus, the device exhibits good electrochromic performance.

In this work, a multicolor visual immunoassay platform was developed. The photoelectric effects of Ag 2 S NPs@ZnO NTs made the color changes of PANI/PB, which enabled visual inspection of CEA. Under the visible light excitation, Ag 2 S NPs@ZnO NTs generates electron-holes. Where, photoelectrons will pass electrical circuit to PB and photoinduced holes will oxidize PANI, which making the PANI/PB composite changes from emerald green-blue-purple-black colors. When CEA was incubated, the migration rate of photogenerated carriers is slowed down owing to the steric hindrance , resulting in different color changes of PANI/PB. In addition, the average green channel of PANI/PB read by photoshop has a certain correlated linear relationship with the concentration of CEA. Meanwhile, we can observe the color transformation of PANI/PB with our own eyes. By integrating advantages of photoelectrochemistry and colorimetry , the linear range of CEA detection was 0.1–20 ng/mL, and the detection limit was 0.05 ng/mL (S/N = 3). More importantly, this multicolor sensing method is very convenient, simple and low-cost. The photocarriers-modulated colorimetric strategy also provides a novel idea for visual portable platform design in clinical diagnosis.

Healing of infected chronic wounds faces dual challenges: persistent inflammation and impaired angiogenesis. To address these, SN-PB@PG nanocomplexes were prepared by hybridisation of nitroprusside (SNP) with Prussian blue (SN-PB NPs) and loaded with prodigiosin (PG). Under near-infrared (NIR) irradiation, SN-PB NPs generated mild hyperthermia, facilitating the release of nitric oxide (NO) and PG to combat bacterial biofilms and multidrug-resistant pathogens. The in vivo assay using diabetic infected wounds demonstrated that SN-PB@PG NPs with NIR reduced the wound area to 10.6% by the 11th day, which is superior to that of control group (29.6%). In the flap transplantation experiments, the data showed SN-PB@PG NPs with NIR group only have a necrobiosis of 3.8% of flaps on the 8th day, which is superior to 31.3% of the control group. Additionally, the release of NO promoted vascular regeneration by up-regulating vascular endothelial growth factor (VEGF) and platelet endothelial cell adhesion molecule-1 (CD31), and regenerated sarcomeric tissue by down-regulating MMP-9. The results indicated that the combination of SN-PB@PG NPs with gas and photothermal therapy exerted a combined antibacterial and wound healing effect. Compared to traditional clinical methods such as surgical debridement and hyperbaric oxygen therapy, this new strategy efficiently addresses issues of infection and healing, which is convenient for clinical application.

Mg Al layered double hydroxides (LDHs) intercalated by Mo 3 S 13 2− and MoS 4 2− (Mo 3 S 13 -LDHs/MoS 4 -LDHs) were prepared through the ion exchange method and compared their removing ability of Cu(II), Pb(II) from wastewater. When the batch experiment conducted at dosage 0.3 g/L, pH neutral, contact time 360 min, concentration 6 mmol/L and temperature 298 K, the adsorption capacity of Cu(II)/Pb(II) onto Mo 3 S 13 -LDHs and MoS 4 -LDHs was 2.76, 4.85 and 2.15, 4.66 mmol/g, Mo 3 S 13 -LDHs showed a higher adsorption capacity, which was because the larger amount of adsorption sites on Mo 3 S 13 2− . In mixed systems, Mo 3 S 13 -LDHs/MoS 4 -LDHs exhibited the preferential selectivity of Pb(II). When Mo 3 S 13 -LDHs/MoS 4 -LDHs adsorbed the low concentrations of Cu(II)/Pb(II), Mo 3 S 13 2− /MoS 4 2− first captured heavy metals and fixed into the interlayer. With the increase of concentration, Cu(II)/Pb(II) were still captured by the interlayered Mo 3 S 13 2− unlike MoS 4 -LDHs that hydroxyl groups onto LDHs began to capture Cu(II)/Pb(II). In the dynamic adsorption experiment, Mo 3 S 13 -LDHs could treat a larger volume of sewage than MoS 4 -LDHs. Mo 3 S 13 -LDHs exhibited better selectivity for Cu(II)/Pb(II) under the interference of organic and other metal ions in wastewater, and heavy metals after the treatment by Mo 3 S 13 -LDHs were more stable in the environment. Therefore, Mo 3 S 13 -LDHs could be considered as an environmentally stable adsorbent to remove heavy metals from wastewater compared to MoS 4 -LDHs.

It is still an urgent task to design metal coatings for the development of corrosion resistance . Herein, Pb-Co-ZrO 2 coating is fabricated on the surface of aluminum plates via one-step pulsed electrodeposition for corrosion resistance. The pulse frequency, current density and duty cycle are 800 Hz, 15 mA cm −2 and 20 %, respectively. In this work, the concentration of ZrO 2 nanoparticles in the bath is the main operating variable. We further explored the deposition mechanism of the nanocomposite coating and demonstrated its application potential in corrosion resistance. As expected, the corrosion resistance and mechanical properties of the coatings increased and then decreased with the increase of the concentration of ZrO 2 nanoparticles in the plating solution. When the concentration of ZrO 2 nanoparticles in the plating solution was 15 g L −1 , the Pb-Co-ZrO 2 nanocomposite coating exhibited excellent corrosion resistance in 3.5 wt% NaCl solution, with an impedance modulus value (5182 Ω cm 2 ) that was eight times higher than that of the pure Pb coating (669 Ω cm 2 ), possessed the highest corrosion potential (- 0.60 V) and the lowest corrosion current density (3.6 μA cm −2 ), while also exhibiting excellent mechanical properties. The mechanism of the improved corrosion performance of the Pb-Co-ZrO 2 composite coatings was further explained using DFT calculations. The results show that the coupling between the interface of Pb-Co solid solution and ZrO 2 nanoparticles effectively improves the overall electron figure of merit of the coatings and triggers an obvious electron localisation, which increases the energy required for the interfacial electrons to escape from the coating interface.

Lead (Pb) is a common and toxic metal pollutant in the ecological environment and has drawn significant attention due to its presence in various channels, including the use of lead-based paint, mineral extraction and smelting, exhaust gas from gasoline combustion. Autophagy is an essential catabolic pathway and blocked autophagy may result in abnormal lipid metabolism in liver. A body of evidence demonstrates that Pb exposure causes abnormal lipid droplet (LDs) accumulation in the liver, but the mechanism remains unknown. Here, we investigated whether Pb induced lipid accumulation by regulating autophagy in HepG2 cells. In this study, we found that Pb (50 μM) blocked the autophagy flux mainly by transcription factor EB (TFEB)-mediated impairment of lysosome formation and activity. Then we demonstrated that the dense lipid accumulation was observed upon Pb exposure, and induction of autophagy by the autophagy activator rapamycin (Rap) alleviated Pb-induced lipid accumulation, while suppression of autophagy by chloroquine (CQ) exacerbated Pb-induced lipid accumulation, suggested that Pb-induced autophagy blockage might be responsible for lipid accumulation. Moreover, we demonstrated that the SIRT1/mTOR pathway participated in Pb-induced autophagy dysregulation, leading to Pb-induced hepatic lipid accumulation. In summary, these results revealed a new insight into the relationship between Pb-caused autophagy dysregulation and lipid accumulation for the first time and highlight autophagy as a novel therapeutic target against Pb-induced hepatic lipid accumulation which supplying the theoretical basis and potential strategies for the intervention and treatment of Pb-related disease.

A novel macroporous (~150 μm) double network hydrogel (TR/PAA) was prepared from tea residue and acrylic acid, and its performance was systematically evaluated. The static adsorption experiments showed that gel exhibited high selectivity and adsorption capacity, ultrafast kinetics (~10 min) for Cr(III), Pb(II) and Fe(III). The adsorption behavior showed heterogeneous and chemisorption process adsorption capacities of 206.19, 253.16, and 94.88 mg g −1 for Cr(III), Pb(II) and Fe(III), respectively. In pluralistic systems, TR/PAA showed the adsorption order of Fe(III) > Cr(III) > Pb(II). Mechanism studies confirm that nitrogen and oxygen-containing functional groups play a major role in the adsorption process. In the fixed-bed column experiments, the treatment volume of simulated wastewater reached 1400 bed volumes (BV) (21.6 L), producing only 7 BV (323 mL) eluent. This work provides a new avenue for the combination of TR/PAA reuse and heavy metal removal, which is expected to be applied in actual wastewater treatment.

Arg-Mt, was fabricated by modifying sodium montmorillonite (Na-Mt) with Arginine monohydrochloride (Arg salt), to adsorb Pb(II) and Cu(II) in aqueous solution. The X-ray powder diffraction (XRD), Fourier transform infrared (FTIR) spectrum, thermal analysis (TG/DTG), Brunauer-Emmett-Teller (BET) and Scanning electron microscope (SEM) were employed to investigate the properties of Na-Mt and Arg-Mt. The effects of the amount of modifier, pH value, the initial concentration of M(II), temperature and contact time were tested in a single adsorption system. The isotherm model was well matched with the Langmuir curve and the kinetic adsorption fitted well with the pseudo-second-order rate equation. The saturated adsorption of Pb(II) and Cu(II) by Arg-Mt were 124.69 and 29.15 mg/g, respectively, which were higher than that of Na-Mt (89.08 and 23.93 mg/g). The thermodynamic equation indicated that the adsorption process was spontaneous, endothermic, and the randomness of the samples changed a little after adsorption. The adsorption capacity of heavy metal ions in the binary co-adsorption system was poor than single adsorption system. Furthermore, the adsorbed M(II) onto Arg-Mt can hardly be dissolved under weak acidic condition (pH > 4) according to the desorption experiments. High-efficiency and low-cost make Arg-Mt to be used in the removal of heavy ions in aqueous solution.

A new adsorbent (MOFs-DHAQ) was prepared by functionalizing UiO-66-NH 2 with 1,8-dihydroxyanthraquinone to remove Pb(II) from wastewater. The optimum pH, adsorption kinetics and adsorption isotherms were studied. MOFs-DHAQ has a good removal rate for Pb(III) at pH 4. It takes only 30 min to reach maximum adsorption capacity about 213.3 mg/g. The experimental data conforms to the pseudo-secondary kinetics and the Freundlich models. The adsorption process belongs to multilayer chemical adsorption . Desorption and adsorption experiments indicate that the adsorbent can be recycled at least four times. The rising temperature favors the adsorption of Pb(II) on MOFs-DHAQ because the adsorption process is a spontaneous endothermic reaction. The interaction mechanism between Pb(II) and the reactive group is mainly electrostatic interaction and complexation. MOFs-DHAQ has excellent selectivity for removing Pb(II) from wastewater contains a variety of interfering ions. The calculated adsorption capacity ( Q ex ) of Pb(II) for column adsorption was 108.04 mg/g and was consistent with the Thomas model's adsorption capacity( Q Th ) about 109.63mg/g. Density functional theory calculations show that MOFs-DHAQ combines with Pb(II) through monodentate N atoms and bidentate O groups. MOFs-DHAQ has good application prospect in the removal of lead from wastewater.

Owing to narrow band gap and low toxicity, tin–lead (Sn–Pb) hybrid perovskites have shown great potential in photovoltaic applications, and the highest power conversion efficiency (PCE) of Sn–Pb perovskite solar cells (PSCs) has recently reached 23.6%. However, it is still challenging to prepare Sn–Pb films in open-air condition due to the Sn2+ oxidation of the precursor solution under this condition. In this work, we report the stabilizing of the Sn–Pb perovskite precursor solution by using ionic liquid methylammonium acetate (MAAc) as the solvent, which enables the fabrication of Sn–Pb films in air. MAAc is found to coordinate with the Sn–Pb precursor via abundant hydrogen bonding, which stabilizes the colloids and protects the Sn2+ stability in the precursor solution in air. Therefore, the durability of the Sn–Pb precursor solution based on the MAAc solvent is greatly improved, which enables the fabrication of efficient PSCs and achieves a champion PCE of ∼16% with robust device stability. Moreover, due to the chemical interactions of MAAc with Sn–Pb perovskites, the Pb leakage is also suppressed in the MAAc-based Sn–Pb PSCs. This work demonstrates a feasible strategy for reliable fabrication of Sn–Pb PSCs, which could also be applied in many other optoelectronic devices.

The growing issue of Pb 2+ ions contamination in marine environments necessitates the development of effective adsorbents to significantly mitigate this ecological challenge. In response, a novel composite material comprising layered double hydroxide (LDH), boron nitride (BN), and tin ferrite (SnFe 2 O 4 ) was synthesized for the removal of Pb 2+ ions. The synthesized SnFe 2 O 4 /BN/NiAl-LDH composite was characterized using FTIR, XRD, ZP, SEM, and XPS techniques. Pb 2+ ions removal reached equilibrium within 30 minutes, with a removal efficiency of 95.42%. Pb 2+ removal efficiency increased progressively in the following order based on the data: SnFe 2 O 4 /BN/NiAl-LDH (1:1) > SnFe 2 O 4 /BN/NiAl-LDH (3:1) > SnFe 2 O 4 /BN/NiAl-LDH (1:3). Furthermore, the experimental data were consistent with the Langmuir and Freundlich isotherms, as well as the pseudo-second-order kinetic model, with a maximum adsorption capacity of 434.8 mg/g. Notably, the composite retained over 70% removal efficiency after five cycles, demonstrating its efficient recyclability. In summary, SnFe 2 O 4 /BN/NiAl-LDH exhibits rapid and efficient adsorption, easy separation, and excellent recyclability.

Carbon black (CB) and heavy metals are the main components of Particulate Matter (PM). Although the individual toxicities of CB and heavy metals have been extensively studied, the combined toxicity is much less understood. In this study, we choose the nano carbon black (CBNPs) and Pb 2+ to simulate fine particles in the atmosphere and study the combined toxic effect on rat alveolar macrophages. The data showed that CBNPs could adsorb Pb 2+ to form CBNPs-Pb 2+ complex and displayed an altered physical properties by particle characterization. CBNPs-Pb 2+ synergistically induced rat alveolar macrophages apoptosis and blocked autophagy flux compared with CBNPs and Pb 2+ individually. Consistent with this, CBNPs-Pb 2+ could impair the mitochondrial membrane potential (MMP), activate apoptotic signaling pathways, inhibit lysosomal function.
