Abstract ：
Wastewater pollutants are a major threat to natural resources, with antibiotics and heavy metals being common water contaminants. By harnessing clean, renewable solar energy, photocatalysis facilitates the synergistic removal of heavy metals and antibiotics. In this paper, MXene was both a template and raw material, and MXene-derived oxide (TiO2) and SnIn4S8 Z-scheme composite materials were synthesized and characterized. The synergistic mode of photocatalytic reduction and oxidation leads to the enhanced utilization of e(-)/h(+) pairs. The TiO2/SnIn4S8 exhibited a higher photocatalytic capacity for the simultaneous removal of tetracycline (TC) (20 mg center dot L-1) and Cr(VI) (15 mg center dot L-1). The main active substances of TC degradation and Cr(VI) reduction were identified via free radical scavengers and electron paramagnetic resonance (EPR). Additionally, the potential photocatalytic degradation route of TC was thoroughly elucidated through liquid chromatography-mass spectrometry (LC-MS).

Abstract ：
Background: Energy shortages and environmental pollution are two of the most immediate problems all over the world. Photocatalysis is expanding into energy and environmental applications. Methods: In this study, novel visible-light-driven Ag2WO4/AgVO3 composite photocatalysts were constructed via a one-pot, controllable, ligand-free and eco-friendly approach and analyzed using different techniques. Under visible light irradiation, photocatalytic behavior of type-II heterojunctions in the degradation of levofloxacin hydrochloride is investigated. Significant findings: Various characterizations showed that Ag2WO4 was successfully loaded onto the AgVO3 surface, which improved the separation and transfer efficiency of the photogenerated charge carriers. Under optimal experimental conditions, the removal efficiency of levofloxacin reached 0.0194 min-1 for the Ag2WO4/ AgVO3 composites with a 3 : 5 mass ratio (3-WV), which was 5.87 and 17.64 times that of pure AgVO3 and Ag2WO4, respectively. The photocatalytic mechanism of typical type-II heterojunction was discussed. Furthermore, possible photodegradation pathway of levofloxacin was comprehensively determined by LC-MS analysis. This work will provide new motivation for the design and synthesis of simple preparation and highly efficient photocatalysts for environmental purification.

Abstract ：
Background: The accumulation of antibiotics in water systems has received considerable global attention due to its detrimental effects. There is an urgent need to develop rapid and efficient methods for the degradation of antibiotics.Methods: In this work, a highly efficient AgFeO2/Ag3VO4 photocatalyst was successfully fabricated by a hydrothermal method and analyzed using different techniques. Under visible light irradiation, photocatalytic behavior of AgFeO2/Ag3VO4 heterojunctions in the degradation of levofloxacin is investigated. Significant findings: The results showed that p-n heterojunction was formed between AgFeO2 and Ag3VO4, which improved the separation and transfer of photogenerated charge carrier under the action of the internal electric field. The apparent reaction rate of AgFeO2/Ag3VO4 heterostructure toward degradation of levofloxacin reached to 0.2770 min-1, which was about 2.15 times and 36.73 times larger than those of Ag3VO4 and AgFeO2, respectively, and much larger than other counterparts. Furthermore, possible photocatalytic degradation pathway of levofloxacin was comprehensively determined by LC-MS analysis. This work would provide in-depth understanding on the efficient photocatalytic removal of antibiotics for sustainable environmental remediation.

Abstract ：
Background: The role of thioredoxin-interacting protein (TXNIP) in lipopolysaccharide-induced liver injury in mice has been reported, but the underlying mechanisms are poorly understood. Methods: We overexpressed deubiquitinase in cells overexpressing TXNIP and then detected the level of TXNIP to screen out the deubiquitinase regulating TXNIP; the interaction between TXNIP and deubiquitinase was verified by coimmunoprecipitation. After knockdown of a deubiquitinase and overexpression of TXNIP in Huh7 and HepG2 cells, lipopolysaccharide was used to establish a cellular inflammatory model to explore the role of deubiquitinase and TXNIP in hepatocyte inflammation. Results: In this study, we discovered that ubiquitin-specific protease 5 (USP5) interacts with TXNIP and stabilizes it through deubiquitylation in Huh-7 and HepG2 cells after treatment with lipopolysaccharide. In lipopolysaccharide-treated Huh-7 and HepG2 cells, USP5 knockdown increased cell viability, reduced apoptosis, and decreased the expression of inflammatory factors, including NLRP3, IL-1 beta, IL-18, ASC, and procaspase-1. Overexpression of TXNIP reversed the phenotype induced by knockdown USP5. Conclusions: In summary, USP5 promotes lipopolysaccharide-induced apoptosis and inflammatory response by stabilizing the TXNIP protein.

Abstract ：
Background and Objectives: Targeted drug is often engulfed and cleared by the reticuloendothelial system in vivo, resulting in reduced treatment efficacy. This study aimed to explore the biodistribution and HER-2-targeted antitumor effects of trastuzumab-modified gold nanorods (Tra-AuNRs) in a gastric cancer animal model. Methods: Gold nanorods were synthesized using a seed-mediated growth method, and then subjected to trastuzumab-targeted modification. Elemental analysis, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy were performed; UV-visible absorption peak, photothermal effects, morphology, and size distribution of Tra-AuNRs were characterized. The targeted killing effect of Tra-AuNRs on gastric cancer cells was assessed in vitro. Tra-AuNRs were injected intravenously and intratumorally into gastric cancer-bearing nude mice in vivo and their distribution was detected. Tumor growth inhibition rate and tumor apoptosis-related protein expression were compared between groups. Results: Tra-AuNRs presented a relatively uniform morphology with an average particle size of 59.9 nm and a longitudinal plasmon resonance absorption peak of 790 nm. The targeted killing rate of gastric cancer cells in vitro by Tra-AuNRs was 87.9%. After intravenous injection, Tra-AuNRs were mainly distributed in the liver, tumor, spleen, and lungs. Comparatively, Tra-AuNRs were mainly distributed in the tumor when intratumorally injected, with a tumor concentration of 6.42 mu g/g after 24 h. The tumor growth inhibition rate reached 78.3% in the intratumoral injection group, with significantly higher BAX, BAD, and CASPASE-3 expression than that in the intravenous injection group. Conclusion: The findings suggest that Tra-AuNRs can be used for HER-2-positive gastric cancer treatment. Intratumoral injection of Tra-AuNRs significantly increased the local tumor drug concentration and improved the molecular targeted antitumor growth effect in gastric cancer-bearing nude mice.

Abstract ：
Two-dimensional (2D) titanium carbide (Ti3C2Tx) with high electrical conductivity and large active surfaces has attracted extensive attention in recent years. Here, in order to address the fire safety and poor electromagnetic shielding performance of polystyrene (PS), a highly effective cetyltrimethyl ammonium bromide-multi-wall carbon nanotubes@Ti3C2Tx (C-MWCNT@Ti3C2Tx) bilayer was deposited on PS sphere to achieve PS@C-MWCNT@Ti3C2Tx (PCT) composites for improving its fire safety and electromagnetic shielding performances. In addition, Ti3C2Tx and gamma-propyl-trimethoxysilane (KH550) were adopted to modify silicon wrapped ammonium polyphosphate (SiAPP-NH2@Ti3C2Tx) via the microencapsulation strategy. Finally, the SiAPP-NH2@Ti3C2Tx was incorporated into PCT composites to fabricate excellent fire-resistant PS composites, i.e. PCTS. The obtained results demonstrated that Ti3C2Tx not only promoted the thermal stability and fire safety but also enhanced the electromagnetic shielding performance of PS. For instance, the PS composite with three number of C-MWCNT@Ti3C2Tx bilayers (PCTS3) exhibited dramatically lowest the peak of heat release rate (528 kW/m(2)) and highest electromagnetic shielding effectiveness value (11 dB), indicative of the excellent flame retardant and considerable electromagnetic shielding properties. This work sheds light on the design of multifunctional multilayer structured polymer composites.

Abstract ：
The solar-to-hydrogen conversion efficiency in photocatalytic water splitting heavily depends on the accumulation of multiple electrons at the catalytically active sites and rapid charge transport/separation. Herein, we demonstrate the construction of 0D-2D nickel-doped and Ti3C2TX MXene (MN)-encapsulated transition metal chalcogenide quantum dot (TMC QD:Ni)/Ti3C2TX MN heterostructures via an elaborate electrostatic self-assembly strategy. The mechanistic studies revealed that the defects induced by atomic-level foreign metal ion doping create a mid-bandgap state, which broadens the optical absorption range and extends the photo-excited carrier lifetime of the TMC QDs. The density functional calculation results verified that Ni2+ ion doping introduces a donor impurity level and increases the density of state at the valence band maximum, leading to a significant increase in the number of active sites and lower energy barrier for photocatalytic hydrogen evolution. The subsequent self-assembly of TMC QDs:Ni on the Ti3C2TX MN framework further accelerates the charge separation and transfer due to the formation of an ideal unidirectional electron migration pathway by Ti3C2TX MN, which functions as an electron-withdrawing mediator. The synergistic effect of Ni2+ ion doping and Ti3C2TX MN decoration significantly decreases the charge transfer resistance at the photosensitizer (TMC QD)/co-catalyst (Ti3C2TX MN) interface and promotes the chemisorption of protons on the catalyst surface, resulting in an excellent solar-to-hydrogen conversion efficiency. Our work provides valuable guidance for the rational design of high-efficiency photocatalysts via precise atomic-level metal ion doping and co-catalyst modulation towards emerging artificial photosynthesis.

Abstract ：
Freestanding electrodes without the influences of additives have been considered as a kind of ideal electrode structure in the field of capacitive deionization (CDI). However, subjected to conductivity, available surface areas, hydrophilicity and etc., effectively construction of freestanding CDI electrodes with high water desalination performance still face great challenges. Herein, we will demonstrate a unique N-doped graphene freestanding porous membrane electrode with excellent water desalination performance. The preparation process mainly includes the assembly of core-shell composites with incomplete graphene oxide shells into bulk membranes using compression molding method and the heat-treatment under NH3 atmosphere. These reserved spherical shells with loopholes and N-doping make up the freestanding membrane electrodes with network porous architecture. The interconnected sphere shells efficiently improve the availability of surface and pores in the monolithic assembly, while the doping of nitrogen element further enhances the accessibility of graphene-based surface by the electrolyte. As a result, such graphene carbonaceous freestanding electrodes exhibit excellent water desalination performance with a high CDI capacity of about 21.8 mg/g in NaCI solution. Moreover, such freestanding membrane electrodes also possess good desalination abilities towards some other salts such as KCI, CaCl2 and MgCl2, suggesting their potential applications in complex brine solution.
