1Novel synthesis of fly-ash-derived Cu-loaded SAPO-34 catalysts and their use in selective catalytic reduction of NO with NH3显示文摘A combined acid–alkali hydrothermal method was used to prepare fly ash–derived SAPO-34 molecular sieves from a thermal power plant in Inner Mongolia(China).The specific surface area of the prepared fly-ash-derived SAPO-34 molecular sieves was 579 m^2 g^-1,the total pore volume was about 0.27 cm^3 g^-1,and the pore size was 0.56 nm;the molar ratios of Al2O3:P2O5:SiO2 were 1:0.86:0.45.Cu/SAPO-34 catalysts were prepared by impregnation of low-cost fly-ash-derived SAPO-34 molecular sieves as a support and tested in selective catalytic reduction with NH3(NH3-SCR).Powder X-ray diffraction(XRD),N2 adsorption–desorption,X-ray photoelectron spectroscopy(XPS),H2 temperatureprogrammed reduction(H2-TPR),NH3 temperature-programmed desorption(NH3-TPD),electron paramagnetic resonance(EPR),nuclear magnetic resonance(NMR),X-ray fluorescence analysis(XRF)and scanning electron microscopy(SEM)were used for catalyst characterization and investigation of the relationships between the catalyst structure and the catalytic activity.The actual silica:alumina ratio of the molecular sieves did not increase with increasing Cu loading,indicating that increasing the Cu loading does not change the original structure of the SAPO-34 molecular sieves.The XRF and NMR results showed that replacement by Cu results in more Si islands.The molecular sieve acidity decreased because of the increased number of Si islands.The NH3-TPD results showed that for the Cu/SAPO-34 catalysts there was a low correlation between the low-temperature activity and the amount of acidic sites.SCR activity is closely related to the location of Cu.The 4.47 Cu/SAPO-34 catalyst has the highest isolated Cu2+showed the highest NH3-SCR activities(>90%)at 250–350℃.This work opens up new avenues for recycling fly ash formed in coal-fired power plants(reducing environmental pollution)and developing low-cost SCR catalysts for NOx pollution control.Ge Li Baodong Wang Qi Sun Wayne Qiang Xu Ziran Ma Hongyan Wang Daojun Zhang Jiali Zhou 2019Green Energy & Environment2019,4,4:6
2Liquid-liquid phase separation in human health and diseases显示文摘Emerging evidence suggests that liquid-liquid phase separation(LLPS)represents a vital and ubiquitous phenomenon underlying the formation of membraneless organelles in eukaryotic cells(also known as biomolecular condensates or droplets).Recent studies have revealed evidences that indicate that LLPS plays a vital role in human health and diseases.In this review,we describe our current understanding of LLPS and summarize its physiological functions.We further describe the role of LLPS in the development of human diseases.Additionally,we review the recently developed methods for studying LLPS.Although LLPS research is in its infancy-but is fast-growing-it is clear that LLPS plays an essential role in the development of pathophysiological conditions.This highlights the need for an overview of the recent advances in the field to translate our current knowledge regarding LLPS into therapeutic discoveries.Bin Wang Lei Zhang Tong Dai Ziran Qin Huasong Lu Long Zhang Fangfang Zhou 2021Signal Transduction and Targeted Therapy2021,6,9:4
3Alterations in microbiota of patients with COVID-19:potential mechanisms and therapeutic interventions显示文摘The global coronavirus disease 2019(COVID-19)pandemic is currently ongoing.It is caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).A high proportion of COVID-19 patients exhibit gastrointestinal manifestations such as diarrhea,nausea,or vomiting.Moreover,the respiratory and gastrointestinal tracts are the primary habitats of human microbiota and targets for SARS-CoV-2 infection as they express angiotensin-converting enzyme-2(ACE2)and transmembrane protease serine 2(TMPRSS2)at high levels.There is accumulating evidence that the microbiota are significantly altered in patients with COVID-19 and post-acute COVID-19 syndrome(PACS).Bin Wang Lei Zhang Yongqiang Wang Tong Dai Ziran Qin Fangfang Zhou Long Zhang 2022Signal Transduction and Targeted Therapy2022,7,5:3

8Effect of manganese and/or ceria loading on V_2O_5-MoO_3/TiO_2 NH_3 selective catalytic reduction catalyst显示文摘The effect of manganese and/or ceria loading of V2 O5-MoO3/TiO2 catalysts was investigated for selective catalytic reduction(SCR) of NOx by NH3.The manganese and/or ceria loaded V2 O5-MoO3/TiO2 catalysts we re prepared by the wetness impregnation method.The physicochemical characteristics of the catalysts were thoroughly characterized.The catalytic performance of 1.5 wt% V2 O5-3 wt% MoO3/TiO2(V1.5 Mo3/Ti) is greatly enhanced by addition of 2.5 wt% MnOx and 3.0 wt% CeO2(V1.5 Mo3 Mn2.5 Ce3/Ti) below450℃.Compared with the V1.5 Mo3/Ti catalyst with NOx conversion of 75% at 275 ℃,V1.5 Mo3 Mn2.5 Ce3/Ti exhibits higher NOx conversion of 84% with good resistance to SO2 and H2 O at a gas hourly space velocity value of 150000 h-1.The active manganese,cerium,molybdenum,and vanadium oxide species are highly dispersed on the catalyst surface and some synergistic effects exist among these species.Addition of MnOx significantly enhances the redox ability of the cerium,vanadium,and molybdenum species.Addition of Ce increases the acidity of the catalyst.More active oxygen species,including surface chemisorbed oxygen,form with addition of Mn and/or Ce.Because of the synergistic effects,appropriate proportions of manganese in different valence states exist in the catalysts.In summary,the good redox ability and the strong acidity contribute to the high NH3-SCR activity and N2 selectivity of the V1.5 Mo3 Mn2.5 Ce3/Ti catalyst in a wide temperature range.And the V1.5 Mo3 Mn2.5 Ce3/Ti catalyst shows good resistance to H2 O and SO2 in long-time catalytic testing,which can be ascribed to the highly sulfated species adsorbed on the catalyst.Daojun Zhang Ziran Ma Baodong Wang Tao Zhu Duan Weng Xiaodong Wu Jingyun Chen Hongyan Wang Ge Li Jiali Zhou 2020Journal of Rare Earths2020,38,7:1

10Gold nanoparticles combat enveloped RNA virus by affecting organelle dynamics显示文摘Enveloped RNA viruses are a group of viruses with an outer membrane derived from a host cell and a genome consisting of ribonucleic acid(RNA).These viruses rely on host cell machinery and organelles to replicate and assemble new virus particles.However,the interaction between viruses and host organelles may be disrupted by nanomaterials,such as gold nanoparticles(AuNPs)with unique physical and chemical properties.In this study,we investigated the effects of AuNPs with different surface charge properties on the subcellular structure and function of mammalian cells,and their effects on two representative enveloped RNA viruses:lentivirus and human coronavirus OC43(HCoV-OC43)antiviral potential.By comparing the subcellular effects of AuNPs with different surface charge properties,we found that treatment with AuNPs with positive surface charges induced more significant disruption of subcellular structures than neutrally charged AuNPs and negatively charged AuNPs,mainly manifested in lysosomes and Cytoskeletal disorders.The antiviral effect of the surface positively charged AuNPs was further evaluated using lentivirus and HCoV-OC43.The results showed that AuNPs had a significant inhibitory effect on both lentivirus and HCoV-OC43 without obvious side effects.In conclusion,our study provides insights into the mechanism of action and biocompatibility of AuNP in biological systems,while supporting the potential of targeting organelle dynamics against enveloped RNA viruses.Fangzhou Li Qianqian Huang Ziran Zhou Qiongge Guan Fei Ye Baoying Huang Weisheng Guo Xing-Jie Liang 2023Signal Transduction and Targeted Therapy2023,8,9:0
11Modularly engineered prodrug-nanoassemblies for cancer therapy:Nonpharmacological moiety dominating delivery fates显示文摘Self-engineered small-molecule prodrug-nanoassemblies have emerged as promising nanomedicines for cancer treatment.Modular design of prodrug molecules is crucial to guarantee the favorable assembly stability,tumor-specific prodrug activation,and satisfactory antitumor effect.However,too much attention has been paid to the pharmacophores and chemical linkages in prodrug molecules while neglects the vital roles of nonpharmacological moieties.Herein,we found that iso-carbon fatty acids with different number,position,and cis-trans configuration of double bonds dramatically affect the nanoassembly feature and drug delivery fates of thioether-linked paclitaxel prodrug-nanoassemblies.Particularly,the number and cis-trans configuration of double bonds in fatty acid moieties not only dominate the self-assembly ability and colloidal stability of prodrugs,but also exert significant influences on the pharmacokinetics,prodrug activation,and antitumor activity of prodrug-nanoassemblies.Finally,oleic acid with one cis double bond stands out as the optimal nonpharmacological moiety for thioether-linked paclitaxel prodrugnanoassemblies.This study elucidates the crucial roles of nonpharmacological moieties in prodrugs,and provides new insights into the modular design of prodrug-based nanomedicines for cancer therapy.Yuequan Wang Qian Qiu Rui Liao Xinhui Wang Ziran Zhou Xuanbo Zhang Haotian Zhang Zhonggui He Shenwu Zhang Cong Luo Jin Sun 2023Nano Research2023,16,1:0

13Genome-wide identification and spatiotemporal expression profiling of zinc finger SWIM domain-containing protein family genes显示文摘The biological function of the novel zinc-finger SWIM domain-containing protein family(ZSWIM)during embryonic development remains elusive.Here,we conducted a genome-wide analysis to explore the evolutionary processes of the ZSWIM gene family members in mice,Xenopus tropicalis,zebrafish,and humans.We identified nine putative ZSWIM genes in the human and mouse genome,eight in the Xenopus genome,and five in the zebrafish genome.Based on multiple sequence alignment,three members,ZSWIM5,ZSWIM6,and ZSWIM8,demonstrated the highest homology across all four species.Using available RNA sequencing(RNAseq)data,ZSWIM genes were found to be widely expressed across different tissues,with distinct tissuespecific properties.To identify the functions of the ZSWIM protein family during embryogenesis,we examined temporal and spatial expression patterns of zswim family genes in Xenopus embryos.Quantitative real-time polymerase chain reaction(qRT-PCR)revealed that each member had a distinct expression profile.Whole-mount in situ hybridization showed that both zswim1 and zswim3 were maternally expressed genes;zswim5 and zswim6were expressed throughout embryogenesis and displayed dynamic expression in the brain,eyes,somite,and bronchial arch at the late tailbud stages;zswim7 was detected in the eye area;zswim8 showed a dynamic expression pattern during the tailbud stages,with expression detected in the brain,eyes,and somite;zswim9 was faintly expressed throughout embryonic development.This study provides a foundation for future research to delineate the functions of ZSWIM gene members.Imtiaz Ul Hassan Hafiz Mamoon Rehman Ziran Liu Liangji Zhou Muhammad Kaleem Samma Chengdong Wang Zixin Rong Xufeng Qi Dongqing Cai Hui Zhao 2023Zoological Research2023,44,3:0
14Research progress in green synthesis of ammonia as hydrogen-storage carrier under‘hydrogen 2.0 economy’显示文摘Hydrogen energy is characterized by its environmental friendliness,high efficiency,lack of carbon emissions and wide range of applications.However,its transportation and storage are challenges that limit further development of the hydrogen-energy industry.Ammonia is a carbon-free hydrogen-rich carrier.The storage of hydrogen in ammonia has unique advantages of high energy density,easy storage and transportation,reliable safety,a mature industrial foundation and no tail-end carbon emissions.However,industrial ammonia synthesis still heavily relies on the Haber-Bosch process,which accounts for significant energy consumption and greenhouse gas emissions.Therefore,the development of green and sustainable ammonia-synthesis methods is extremely important and urgent.Recently,ammonia-synthesis technologies such as electrocatalysis,photocatalysis,photoelectrocatalysis and biocatalysis have successfully produced ammonia from nitrogen and water,resulting in lower costs.The nitrogen-reduction-reaction conditions of these methods are mild and can be carried out under ambient temperatures and atmospheric pressure with low energy consumptions.Meanwhile,these methods bypass the traditional hydrogen-production section and their routes are simpler.Therefore,these technologies can be used to flexibly integrate renewable energy,including intermittent renewable energy,to achieve distributed ammonia synthesis.These benefits contribute to both global energy and environmental sustainability goals.In this study,the mechanisms of ammonia synthesis under ambient conditions are reviewed and the technical difficulties of various catalysts for ammonia synthesis are summarized.Based on the optimization strategies reported for various catalysts,the high-performing catalysts reported for ammonia synthesis are reviewed and the developmental trend of this field has been forecasted.Ge Li Ziran Ma Jia Zhao Jiali Zhou Shengpan Peng Yonglong Li Baodong Wang 2023Clean Energy2023,7,1:0
15Long-term warming does not affect soil ecoenzyme activity and original microbial nutrient limitation on the Qinghai-Tibet Plateau显示文摘Microbes play an important role in the carbon cycle and nutrient flow of the soil ecosystem.However,the response of microbial activities to long-term warming over decades is poorly understood.To determine how warming changes ecoenzyme activity and microbial nutrient limitation,we conducted a long-term,21 years,experiment,on the Qinghai–Tibet Plateau.We selected typical grass-and shrub-covered plots,used fiberglass open-top chambers(OTCs)to raise the temperature,conducted soil sampling at different depths,studied the response of nutrient-acquiring enzyme activity and stoichiometry,and conducted vector analysis of stoichiometry.Our results showed that long-term warming did not have a notable effect on the activity of nutrient-acquiring enzymes or enzymatic stoichiometry.However,Spearman correlation analysis indicated a significant and positive correlation between ecoenzyme activity and the available nutrients and microbial biomass in soil.Vector analysis of stoichiometry showed phosphorus limitation for all soil microbes at different depths,regardless of whether the soil experienced warming.These changes in enzymatic stoichiometry and vector analysis suggested that microbial nutrient limitation was not alleviated substantially by long-term warming,and warming did not considerably affect the stratification of microbial nutrient limitation.Our research has also shown that long-term warming does not significantly change soil ecoenzyme activity and original microbial nutrient limitation at different soil depths within the OTUsʼimpact range.These results could help improve understanding of microbial thermal acclimation and response to future long-term global warming.Yuanze Li Huakun Zhou Wenjing Chen Yang Wu Lei Lei Qiao ZiRan Yan GuoBin Liu Sha Xue 2022Soil Ecology Letters2022,4,4:0
16Novel pyroptosis-independent functions of gasdermins显示文摘Recently,Rana et al.and Zhang et al.published two studies illustrating the important regulatory roles of gasdermin B(GSDMB)and-D(GSDMD)in inflammatory bowel disease(IBD)and intestinal immune homeostasis maintenance,respectively.1,2 Their findings collectively indicate that the gasdermins(GSDMs)can play a crucial role in restoring epithelial barrier function and shaping gut mucosal homeostasis.Moreover,neither of the functions of GSDMs revealed by these two studies are related to pyroptosis,which may provide new insights into the non-pyroptosis-dependent functions of GSDM proteins.Ziran Qin Fangfang Zhou Long Zhang 2022Signal Transduction and Targeted Therapy2022,7,5:0
