Photo-assisted activation of permonosulfate (PMS) is an effective technology for degradation of organic contaminants. Herein, the cobalt-doped (Co-doped) g-C 3 N 4 photocatalyst was synthesized by the methods of impregnation and calcination. The catalytic activity of Co-doped g-C 3 N 4 catalyst for degradation of RhB in the photo-assisted PMS activation system was obviously higher than that in solo light irradiation or solo PMS-based advanced oxidation processes system. The Co-CN-2 catalyst presents the highest catalytic activity for degradation of RhB in the photo-assisted PMS activation system. 93.5% of RhB was degraded in 10 min by Co-CN-2 catalyst and the kinetic constant of Co-CN-2 catalyst in photo-assisted PMS activation system is 0.267 min −1 , which is 3.71 and 7.36 times to that of Co-CN-2 in solo PMS activation and solo light irradiation system, respectively. The enhanced catalytic activity of Co-CN-2 was mainly attributed to the controllable band structure of g-C 3 N 4 by doping cobalt ions as well as excellent activity of cobalt for PMS activation, and the synergistic interaction between the photo-catalytic and PMS activation plays an important role for degradation of organic pollutants.

Recent advances in torrefaction pretreatment technologies have the potential to improve biomass storage, transportation, and combustion. Torrefaction pretreatment, on the other hand, does not address the issue of high alkali metal content in biomass, which can easily lead to ash deposition, slagging, and corrosion on the boiler heating surface. NH 4 H 2 PO 4 , Ca 3 (PO 4 ) 2 , diatomite (primarily SiO 2 ), and calcined kaolin (Al 2 O 3 ·2SiO 2 ) were added to torrefied wheat straw to control the release and transformation of potassium in the process of biomass combustion, and the effects of additives on K precipitation and migration were explored. The results demonstrated that all four additives might limit the release of K from torrefied wheat straw during combustion. Phosphoric acid additives had a better effect than silicon-aluminum additives, with the best result being Ca 3 (PO 4 ) 2 , followed by calcined kaolin. The amount of phosphoric acid additives should be controlled at 10wt%, and the amount of silicon aluminum additives should be maintained at 5wt%, based on the economy and retention impact of K. XRD and chemical fractionation analysis revealed that phosphoric acid additives primarily control the K transformation by forming K–Ca–P salt and ammonium acetate state K, silica-aluminum additives primarily control it by forming K silicates and aluminosilicates, and diatomite also improved the retention of water-soluble K through physical adsorption.

Alloy-type materials with the characteristics of high theoretical capacity, low sodiation/desodiation potential, and good conductivity are considered as one of the most promising anodes for sodium-ion batteries or capacitors. However, the large volume change during the sodiation leads to poor cyclability and slow kinetics, thus presenting the main issue impeding the practical application. Herein, we propose a facile wet chemistry and pyrolysis method to synthesize Sb-carbon composite that Sb nanoparticles or single atoms are confined and/or dispersed in the wrinkled carbon framework with high nitrogen content. This unique architecture of Sb-carbon composite increases atomic interface contact/interaction with Na + , facilitating ion diffusion and alleviating the volume change of Sb during the charge/discharge process. Half-cell test shows that Sb-carbon composite exhibits a high-rate capability and stable cycling life. Furthermore, sodium-ion capacitors fabricated by employing Sb-carbon composite as anode and home-made active carbon as cathode, deliver both high-energy density of 157 Wh·kg −1 and high-power density of 25 kW·kg −1 as well as excellent cycling performance exceeding 4000 cycles.

Well-dispersed silica-coated FeCo nanocubes are mass prepared using the polyol process and are then amine-functionalized with 1,6- diaminohexane. Further, the almost “matrix-free” soft magnetic nanocomposites (SMNCs) are fabricated using the FeCo nanocubes as bricks, which are cross-linked by epoxy monomers in which the nanoparticles are well separated. These SMNCs exhibit a dense microstructure and extremely high resistivity that limit the eddy current loss, thereby allowing excellent high-frequency inductance performance in a few hundred megahertz and extending the cutoff frequency to 2–7 GHz. The permeability is approximately 8.0 with excellent high-frequency stability at 1 GHz. The quality factor of the nanocomposites exceeds 200 in the 100 MHz range and 500 in the few megahertz range that corresponds to the 36 and 13 nm silica-coating samples, respectively. Furthermore, they exhibit a novel microwave absorbing property with an extremely thin thickness. The absorption approaches − 46.5 dB at 2.41 GHz with only a 1.75 mm nanocomposite absorbing layer. This SMNC presents great potential as multifunction components to satisfy the urgent requirement of wide bandgap semiconductor power in the megahertz range and microwave devices in the gigahertz range.

Enzymatic-based proximity labeling approaches based on activated esters or phenoxy radicals have been widely used for mapping subcellular proteome and protein interactors in living cells. However, activated esters are poorly reactive which leads to a wide labeling radius and phenoxy radicals generated by peroxide treatment may disturb redox-sensitive pathways. Herein, we report a photoactivation-dependent proximity labeling (PDPL) method designed by genetically attaching photosensitizer protein miniSOG to a protein of interest. Triggered by blue light and tunned by irradiation time, singlet oxygen is generated, thereafter enabling spatiotemporally-resolved aniline probe labeling of histidine residues. We demonstrate its high-fidelity through mapping of organelle-specific proteomes. Side-by-side comparison of PDPL with TurboID reveals more specific and deeper proteomic coverage by PDPL. We further apply PDPL to the disease-related transcriptional coactivator BRD4 and E3 ligase Parkin, and discover previously unknown interactors. Through over-expression screening, two unreported substrates Ssu72 and SNW1 are identified for Parkin, whose degradation processes are mediated by the ubiquitination-proteosome pathway.

Na 3 V 2 (PO 4 ) 3 with NASICON structure is regarded as a hopeful cathode in sodium-ion batteries (NIBs). Nevertheless, the immanently inferior electronic conductivity significantly restricts its electrochemical performance and practical application. In this work, a facile solid-state sintering approach employing citric acid as both the reduction agent and carbon source has been developed to prepared Na 3 V 2 (PO 4 ) 3 /C composite. The influence of different sintering temperatures on the structure, morphology, and electrochemical performance of Na 3 V 2 (PO 4 ) 3 /C for NIBs was systematically investigated. The results indicate that the Na 3 V 2 (PO 4 ) 3 /C sample calcined at 850 °C (NVP/C-850) presents the best electrochemical property among the as-obtained four NVP/C samples studied. The optimized NVP/C-850 composite exhibits a reversible capacity of 117.4 mAh/g at 0.2 C, and after 100 cycles, capacity retention of 94.7% was kept. Besides, among the four electrodes, NVP/C-850 electrode exhibited smallest resistance and highest Na + diffusion coefficient. Thus, the outstanding results demonstrate potential application of the NVP/C for NIBs.

Degradation of formaldehyde (HCHO) in interior decoration has been an urgent issue due to its toxicity nature and potential threats to human health. In this work, manganese dioxide nanoparticles (MnO 2 NPs) were in situ grown on the polydopamine (pDA)-templated cotton fabrics for environmentally friendly HCHO degradation applications. The morphology, elemental composition, and crystal structure of the cotton/pDA/MnO 2 were characterized by scanning electron microscopy–energy dispersive X-ray spectrum, Fourier transform infrared, X-ray diffractometer and X-ray photoelectron spectroscopy, respectively. The degradation of HCHO by the as-developed cotton/pDA/MnO 2 was measured in a self-made quartz reactor, and the stability of adsorption was evaluated by cyclic experiments. The results showed that the HCHO removal efficiency reached to 100% within 20 min after three cycles, suggesting that the as-prepared fabrics exhibited good stability for the degradation of HCHO. The development of MnO 2 NPs coated fabrics provides new strategies in degradation HCHO in interior decoration.

In order to enhance the adsorption and photocatalytic property of polyphenylene sulfide (PPS) melt-blown film, PPS melt-blown film was modified by loading ZIF-8 nanomaterial on the surface of the film via a simple solvothermal water method, the PPS melt-blown film was impregnated in advance. Film performance was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM), X-ray diffraction (XRD). Results from FTIR and XRD showed that ZIF-8 was introduced into the modified PPS film successfully. The modified PPS film was endowed with excellent adsorption and photocatalytic compared with the original PPS by the result of enhanced dye removal. The removal rate of methyl blue (MB) by PPS/ZIF-8 film within the range of pH = 3–11 of the environmental solution were more than 80%, up to 99.1%. The dye removal rate still remained 80% after 5 repeat cycles, showed that the modified film has good stability.

Porous carbon is an excellent absorbent for pollutants in water. Here, we report a breakthrough in performance of porous carbon based on lignin prepared using sodium lignosulfonate (SLS), potassium carbonate and melamine as precursor, activator and nitrogen source, respectively. A series of characterization tests confirmed that in-situ nitrogen doping greatly enhanced porous structure, resulting in a specific surface area of 2567.9 m 2 g −1 and total pore volume of 1.499 cm 3 g −1 , which is nearly twice that of non-nitrogen-doped porous carbon. Moreover, adsorption experiments revealed that at 303 K, the saturated adsorption capacity of chloramphenicol was as high as 713.7 mg g −1 , corresponding to an improvement of 33.7%. Further, the prepared porous carbon exhibited a strong anti-interference against metal ions and humic acid. The adsorption process was confirmed to be an endothermic reaction dominated by physical adsorption, indicating that an increase in temperature is conducive to adsorption. The results of this study show that nitrogen-doped lignin-based porous carbon prepared by in-situ doping is a promising material to significantly alleviate water pollution owing to its low cost, excellent pore structure and good adsorption properties.

Background Destruction of pancreatic beta cells is the most typical characteristic of diabetes. Objective We aimed to evaluate the effect of berberine (BBR), a bioactive isoquinoline derivative alkaloid, on beta cell injury. Methods Rodent pancreatic beta cell line INS-1 was treated with 0.5 mM palmitate (PA) for 24 h to establish an in vitro beta cell injury model. Results BBR at 5 µM promoted cell viability, inhibited cell apoptosis and enhanced insulin secretion in PA-induced INS-1 cells. BBR treatment also suppressed PA-induced oxidative stress in INS-1 cells, as evidenced by the decreased ROS production and increased activities of antioxidant enzymes. In addition, suppressed ATP production and reduced mitochondrial membrane potential were restored by BBR in PA-treated INS-1 cells. It was further determined that BBR affected the expressions of mitophagy-associated proteins, suggesting that BBR promoted mitophagy in PA-exposed INS-1 cells. Meanwhile, we found that BBR facilitated nuclear expression and DNA-binding activity of Nrf2, an antioxidative protein that can regulate mitophagy. Finally, a rescue experiment was performed and the results demonstrated that the effect of BBR on cell viability, apoptosis and mitochondrial function in PA-induced INS-1 cells were cancelled by PINK1 knockdown. Conclusions BBR protects islet β cells from PA-induced injury, and this protective effect may be achieved by regulating mitophagy. The present study may provide a novel therapeutic strategy for β cell injury in diabetes mellitus.

Cotton fabric is easy to breed bacteria due to its porous structure and easy wettability, resulting in poor quality of cotton fabric and harm to human health. In order to prepare antibacterial and antifouling cotton fabric, the present work developed a new strategy. The acryloyl chloride (AC) was covalently linked to the surface of cotton fabric by nucleophilic substitution reaction, leading the surface of fabric to have the C=C bonds. Then, the C=C bonds on the treated fabric surface were polymerized with the allyltrimethylammonium chloride (ATAC) via mist polymerization technology, thus making the poly(allyltrimethylammonium chloride) (PTAC) was grafted onto the cotton fabric via grafting through method. As a result, the finished fabric showed excellent antibacterial effect against E. coli and S. aureus , with the bacterial reduction (BR) rates were higher than 99.0 %. Moreover, even after 50 laundering cycles, the BR rates of treated fabric against E. coli and S. aureus were also remained 95.8 %, exhibiting excellent durability. The finished cotton fabric was also showed outstanding antifouling for both bacterial and protein. The antibacterial and antifouling cotton fabric prepared by mist polymerization technology and grafting through method has a great potential application in the household and consumer textiles.

It is significant to explore the advanced oxidation process (AOP) for antibiotic degradation. Herein, a peroxymonosulfate (PMS) activator, Sr 2 FeO 4 /SBA-15 (SFS) heterogeneous catalyst, was synthesized by in situ growth of Sr 2 FeO 4 on the surface of SBA-15. In SFS/PMS catalytic system, Sr atom provided electrons to Fe(II) ↔Fe(III) ↔Fe(II) redox cycle through Sr-O-Fe bonds for PMS activation. The SFS catalyst could activate PMS to generate a free radical coexistence system, including sulfate radical (SO 4 ∙ − ) and hydroxyl radicals (∙OH). The catalyst possessed high catalytic activity and high stability. The degradation efficiency of sulfapyridine (SAD) over the SFS/PMS catalytic system could reach 99.0% after 90 min reaction. After the 5th reuse, the degradation efficiency of SAD was still more than 94.0%, and the phase structure of the catalyst did not alter. The low ion leaching concentration would be more conducive to reuse and avoiding secondary pollution, in comparison to homogeneous catalysts. This catalyst can be widely applied to organic wastewater treatment.-->
