Summary Toxoplasma gondii is a widespread parasitic protozoan causing toxoplasmosis including pulmonary toxoplasmosis. As the first line of host defense, airway epithelial cells play critical roles in orchestrating pulmonary innate immunity. However, the mechanism underlying the airway inflammation induced by the T. gondii infection remains largely unclear. This study demonstrated that after infection with T. gondii , the major anion channel located in the apical membranes of airway epithelial cells, cystic fibrosis transmembrane conductance regulator (CFTR), was degraded by the parasite-secreted cysteine proteases. The intracellular Cl − concentration ([Cl − ] i ) was consequently elevated, leading to activation of nuclear factor-κB (NF-κB) signaling via serum/glucocorticoid regulated kinase 1. Furthermore, the heightened [Cl − ] i and activated NF-κB signaling could be sustained in a positive feedback regulatory manner resulting from decreased intracellular cAMP level through NF-κB-mediated up-regulation of phosphodiesterase 4. Conversely, the sulfur-containing compound allicin conferred anti-inflammatory effects on pulmonary toxoplasmosis by decreasing [Cl − ] i via activation of CFTR. These results suggest that the intracellular Cl − dynamically modulated by T. gondii mediates sustained airway inflammation, which provides a potential therapeutic target against pulmonary toxoplasmosis.

As a poisonous and harmful gas, NO 2 , is not only harmful to the environment, but also detrimental to human health. In this work, ionic liquids (1-hexadecyl-3-methylimidazolium chloride [C 16 Mim] Cl) were selected as dopants to prepare flower-like Cl uniform doped In 2 O 3 nanomaterials. The material exhibits excellent sensing performance to NO 2 under UV light because of Cl uniform doped. Compared with the experiment in dark conditions, the response value of the sensor to 5 ppm NO 2 under UV light is approximately two times higher (S = 425.9) and presents a faster recovery rate (69 s). Chlorine doping shifts the valence band of the material upwards, facilitating the photogenerated electron leap under UV illumination. Moreover, the in-situ DRIFT under UV light were employed to verify the interaction between the materials and NO 2 gas in N 2 , air and O 2 atmospheres respectively. It was found that the presence of oxygen in the environment affects the adsorption of NO 2 on the surface of the Cl doped In 2 O 3 material. This work is of great significance to the sensing mechanism investigation of photo-activated NO 2 gas sensors.

Bi 2 S 3 -based materials with low thermal conductivity and high Seebeck coefficient has been regarded as promising thermoelectric materials for years. To optimize the thermoelectric properties of Bi 2 S 3 materials, (Se, Cl)-co-doped nanostructured Bi 2 S 3 bulks were prepared by hydrothermal method combined with spark plasma sintering . The doping contents of Se and Cl in Bi 2 S 3 depend on the reaction time of the hydrothermal process. A high power factor of 450 μWm −1 K −2 was achieved for Bi 2 S 3 sample with the reaction time of 24 h owing to the substitution of S by Se and Cl. Meanwhile, a low thermal conductivity of 0.35 Wm −1 K −1 is obtained for the Bi 2 S 3 sample with the reaction time of 18 h, owing to the strong phonon scattering caused by the high density of grain boundaries, pores and point defect . Therefore, benefiting from the improved electrical transport properties and reduced thermal conductivity, a peak ZT value of ~ 0.57 was obtained at 673 K for the Bi 2 S 3 sample with the reaction time of 24 h.

It is still challenging to achieve both good stability and high PLQYs for perovskite NCs because of their ionic nature and structural defects. In this work, tungstosilicic acid (TSA) is used for the surface passivation of cesium lead halide perovskite NCs. Near-unity PLQY is achieved for CsPbBr3 NCs after surface passivation with a suitable amount of TSA. XRD in conjunction with XPS analysis shows that TSA binds hydrophobic chains of OAm onto the surface of CsPbBr3 NCs. XPS results also demonstrate that TSA passivation can change the charge distribution of the cations on the surface layers, which can enhance the interaction with surface traps. PL decay analysis reveals that trap states arising from the surface defects are significantly decreased after TSA passivation. TSA-passivated CsPbBr3 NCs demonstrate long-term ambient stability and good resistances to polar solvents and maintain about 80% of their initial PL intensity after storage under ambient conditions for 50 days. It is further found that TSA passivation is able to improve the PLQYs of a broad spectrum of CsPbX3 (X = Cl, Br, I) NCs without hindering the tunability of the band gaps and PL colors of CsPbX3 NCs via anion exchange.

White light-emitting diodes (WLEDs) based on all-inorganic perovskite CsPbX3 (X = Cl, Br, I) quantum dots (QDs) have attracted much attention and rely on mixing several colors of perovskites. However, this inevitably leads to a non-uniform light distribution and serious light loss. Here, a novel strategy was demonstrated to obtain white emission by combining the orange and blue emission from CsPb/Mn(Cl/Br)3 QDs. Notably, highly efficient white emission with a photoluminescence quantum yield of 94% was achieved by an anion exchange surface engineering (AESE) strategy. After AESE treatment the surface traps can be eliminated, resulting in improved exciton and Mn2+ emission. A prototype WLED device was fabricated and exhibited excellent optical stability, demonstrating great potential for perovskite QDs in the field of optoelectronics.

Suspended nano/microstructures on semiconductor surfaces that can manage light are attractive for various on-chip and efficiency-enhanced optoelectronics. Hybrid halide perovskites have shown considerable potential for optoelectronic and photonic applications. However, the ionic and soft lattices of perovskites are sensitive to polar solvents, photons, and heat, limiting the post-processing of suspended microstructures. Herein, a solution-processed selective area homoepitaxial growth (SAEG) method is introduced to create well-ordered, suspended microstructure arrays on the surface of MAPbX 3 (X = Br, Cl) single-crystalline thin films. The suspended micro-arrays exhibit single crystalline structures and 11.2 fold photoluminescence enhancement compared to the thin-film substrates. The success of SAEG lies in the making use of perovskite supersaturated HX aqueous solutions that not only repair surface defects induced by lithography but also satisfy homoepitaxial growth kinetics. This study paves a pathway for the fabrication of cost-effective perovskite surface-suspended microstructures for efficiency-enhanced and on-chip optoelectronic devices.

In the present work, mango pit was used to study the feasibility of converting ionic liquid-pretreated biomass into biofuel and activated biochar by using pyrolysis temperature as a key variable. Ionic liquid 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) was used as a green solvent to dissolve mango pit. The impact of [Bmim]Cl on the pyrolysis properties at peak DTG temperature was investigated. Pretreatment with [Bmim]Cl was observed to slightly enhance biochar yield, while somewhat decreasing bio-oil and biogas yields. The yield of hydrogen and methane, as well as the generation of phenolic and alcoholic bio-oils, are increased by [Bmim]Cl pretreatment. [Bmim]Cl pretreatment was determined to promote the formation of pore structure, a greater number of pores were opened, and the BET surface areas increased 24 times. The pyrolysis kinetics were calculated using the DAEM model. The results showed that [Bmim]Cl pretreatment resulted in lower activation energy and a high amount of fraction mass conversion at low temperatures. As a result, the results showed that pyrolysis of [Bmim]Cl-pretreated biomass did not require high temperatures, and that it is possible to convert ionic liquid pretreatment biomass into high-quality biofuel and active biochar by controlling the pyrolysis temperature.

Graphitized carbonitride (g-C3N4) is widely used in CO2 reduction, hydrogen production, and degradation of toxic chemical dyes and antibiotics. It is a kind of photocatalytic material with excellent performance, and it has the advantages of being safe and nontoxic, having a suitable band gap (2.7 eV), and having a simple preparation and high stability, but because of its fast optical recombination speed and low visible light overutilization, the multifunctional application of g-C3N4 is seriously hindered. Compared with pure g-C3N4, MWCNTs/g-C3N4 have a red-shift in the visible range and a strong absorption in the visible region. Melamine and carboxylated multiwalled carbon nanotubes were used as raw materials to successfully prepare CMWCNT modified g-C3N4 doped with P, Cl by a high temperature calcination method. The effect of the addition amount of P, Cl on the photocatalytic performance of modified g-C3N4 was studied. The experimental results show that the multiwalled carbon nanotubes can accelerate the electron migration, and the doping of P, Cl elements can change the energy band structure of g-C3N4 and reduce the band gap. Through fluorescence analysis and photocurrent analysis, it is known that the incorporation of P, Cl reduces the recombination efficiency of photogenerated electron–hole pairs. In order to explore the application in the degradation of chemical dyes, the photocatalytic degradation efficiency of RhB under visible light was studied. The photocatalytic performance of the samples was evaluated by photodecomposition of aquatic hydrogen. The results showed that when the amount of ammonium dihydrogen phosphate was 10 wt %, the photocatalytic degradation efficiency was the highest, which was 21.13 times higher than that of g-C3N4.

Mechanical force loading is essential for maintaining bone homeostasis, and unloading exposure can lead to bone loss. Osteoclasts are the only bone resorbing cells and play a crucial role in bone remodeling. The molecular mechanisms underlying mechanical stimulation-induced changes in osteoclast function remain to be fully elucidated. Our previous research found Ca 2+ -activated Cl − channel Anoctamin 1 (Ano1) was an essential regulator for osteoclast function. Here, we report that Ano1 mediates osteoclast responses to mechanical stimulation. In vitro, osteoclast activities are obviously affected by mechanical stress, which is accompanied by the changes of Ano1 levels, intracellular Cl − concentration and Ca 2+ downstream signaling. Ano1 knockout or calcium binding mutants blunts the response of osteoclast to mechanical stimulation. In vivo, Ano1 knockout in osteoclast blunts loading induced osteoclast inhibition and unloading induced bone loss and. These results demonstrate that Ano1 plays an important role in mechanical stimulation induced osteoclast activity changes.

Cl− in industrial wastewater from glyphosate production has been used as Cl source to synthesize BiOCl photocatalyst via a simple solvothermal route. The crystalline, morphology, specific surface area and optical properties of photocatalysts prepared under various conditions have been investigated. BiOCl photocatalyst prepared in acidic solution shows the highest crystallinity and without impurities and microcellular structure. The degradation of industrial wastewater contaminants demonstrates the possibility of this BiOCl used in industrial wastewater treatment and phosphorus recycling through the subsequent phosphorus recovery processes. This study not only sheds light on the possibility of photocatalysts’ preparation in situ using industrial wasterwater as raw materials and the feasibility of using photocatalysis technology in wastewater treatment area, but also the chloride ions have been removed as an available resource and the corrosion to treatment facilities has been slowed down. The phosphorus and nitrogen resources can be recycled by other subsequent recycle recoveries. It offers a novel way for the wastewater treatment process in succession from photocatalysts’ manufacture to contaminants disposal.

In this work, using discarded white pomelo peel as the green precursor and hydrochloric acid (HCl) as the dopant, water-soluble Cl-N-doped carbon dots (Cl-NCDs) with excellent performance were synthesized by one-step hydrothermal method. The Cl-NCDs function as both luminescent agents and catalysts, significantly enhancing the chemiluminescence intensity of the HCl-HCHO-KMnO 4 system, forming a novel HCl-HCHO-(Cl-NCDs)-KMnO 4 chemiluminescence system. The addition of erythromycin (EM) solution inhibits the chemiluminescence intensity of new system. By optimizing the conditions, we established a simple, cost-effective, and reliable chemiluminescence method for EM detection, offering a linear range of 5-100 μM and a detection limit of 0.0149 μM. In addition, this method was successfully applied to the analysis of EM in various water simples, achieving recovery rates ranging from 97.6% to 106%.

In this work, PCN-224(Fe) porphyrin-based metal–organic frameworks and a Poly(ionic liquids) (PILs) were used to prepare PCN-224(Fe)@PIL(Cl − ) composite films by UV polymerisation. The structure, morphology, chemical composition, and electrochemical properties of the as-prepared composite film were investigated. PCN-224(Fe) was coated with a kind of P(1-vinylpyridinium chloride as monomer) on the outside to improve the electron transfer efficiency, while an electrochemical system was employed to catalysis the persulfate (PS) decomposition for the efficient degradation of tetracycline (TC). Because of the cathodic reduction reaction, the continuous redox cycle between Fe 3+ /Fe 2+ was facilitated, which enhanced the degradation activity of persulfate on tetracycline. The PCN-224(Fe)@PIL(Cl − ) composite demonstrated a superior electrocatalytic degradation efficiency of 95.8% in just 40 min for the TC model pollutant, surpassing the 63.3% efficiency of pure PCN-224(Fe) within 60 min. This work shows a successful example of using PILs to enhance catalytic degradation activity and points out a direction of preparation of catalysts for activating persulfate (PS).
