1Phosphate removal from domestic wastewater using thermally modified steel slag显示文摘This study was performed to investigate the removal of phosphate from domestic wastewater using a modified steel slag as the adsorbent. The adsorption effects of alkalinity, salt, water,and thermal modification were investigated. The results showed that thermal activation at 800℃ for 1 hr was the optimum operation to improve the adsorption capacity. The adsorption process of the thermally modified slag was well described by the Elovich kinetic model and the Langmuir isotherm model. The maximum adsorption capacity calculated from the Langmuir model reached 13.62 mg/g. Scanning electron microscopy indicated that the surface of the modified slag was cracked and that the texture became loose after heating. The surface area and pore volume did not change after thermal modification. In the treatment of domestic wastewater, the modified slag bed(35.5 kg) removed phosphate effectively and operated for 158 days until the effluent P rose above the limit concentration of 0.5 mg/L. The phosphate fractionation method, which is often applied in soil research, was used to analyze the phosphate adsorption behavior in the slag bed. The analysis revealed that the total contents of various Ca–P forms accounted for 81.4%–91.1%, i.e., Ca10–P 50.6%–65.1%, Ca8–P 17.8%–25.0%,and Ca2–P 4.66%–9.20%. The forms of Al–P, Fe–P, and O–P accounted for only 8.9%–18.6%. The formation of Ca10–P precipitates was considered to be the main mechanism of phosphate removal in the thermally modified slag bed.Jian Yu Wenyan Liang Li Wang Feizhen Li Yuanlong Zou Haidong Wang 2015Journal of Environmental Sciences2015,27,5:13
2A closed-loop process for recycling LiNi_xCo_yMn_((1-x-y))O_2 from mixed cathode materials of lithium-ion batteries显示文摘With the rapid development of consumer electronics and electric vehicles(EV), a large number of spent lithium-ion batteries(LIBs) have been generated worldwide. Thus, effective recycling technologies to recapture a significant amount of valuable metals contained in spent LIBs are highly desirable to prevent the environmental pollution and resource depletion. In this work, a novel recycling technology to regenerate a LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2 cathode material from spent LIBs with different cathode chemistries has been developed. By dismantling, crushing,leaching and impurity removing, the LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2(selected as an example of LiNi_xCo_yMn_(1-x-y)O_2) powder can be directly prepared from the purified leaching solution via co-precipitation followed by solid-state synthesis. For comparison purposes, a fresh-synthesized sample with the same composition has also been prepared using the commercial raw materials via the same method. X-ray diffraction(XRD), scanning electron microscopy(SEM) and electrochemical measurements have been carried out to characterize these samples. The electrochemical test result suggests that the re-synthesized sample delivers cycle performance and low rate capability which are comparable to those of the freshsynthesized sample. This novel recycling technique can be of great value to the regeneration of a pure and marketable LiNi_xCo_yMn_(1-x-y)O_2 cathode material with low secondary pollution.Rujuan Zheng Wenhui Wang Yunkun Dai Quanxin Ma Yuanlong Liu Deying Mu Ruhong Li Jie Rena Changsong Dai 2017Green Energy & Environment2017,2,1:11
3The temporal dynamics of antimicrobial-resistant Salmonella enterica and predominant serovars in China显示文摘Salmonella enterica is one of the most common bacterial pathogens in humans and animals.Systematic studies on the trends and geographical distribution of antimicrobial-resistant Salmonella and dominant serovars have been well studied in European and American countries while not in China.Here,taking the One-Health strategy,we used>35000 Salmonella enterica isolates to explore the temporal and spatial dynamics of dominant serovars in China.We found that Salmonella Typhimurium was the dominant serovar causing human infection in China,which was consistent with Australia but inconsistent with North American and European countries.The proportion of Salmonella serovars Typhimurium,London,Rissen,Corvallis,Meleagridis,Kentucky,and Goldcoast showed an increasing trend during 2006-2019.We randomly selected 1962 isolates for comparative genomics and antimicrobial resistance studies and found that the number of antibiotic resistance genes(ARGs)per isolate increased 1.84 and 2.69 times of human and non-human origins,respectively,spanning 14 years.The proportion of antimicrobial-resistant Salmonella isolates had an increasing trend during 2006-2019,especially beta-lactam,quinolone,tetracycline,and rifampicin resistance.Moreover,we found that higher diversity of sequence types(STs)in S.Typhimurium than in other serovars,ST34 from pig and ST 19 from chicken origin,were mainly associated with isolates causing child and adult gastro-infection,respectively.Our results fill in the data gap on the trends of dominant serovars and antimicrobial resistance of Salmonella enterica in China.These data provide useful information for public health decision-makers prioritizing interventions for foodborne diseases and food safety.Yanan Wang Yue Liu Na Lyu Zhiyuan Li Sufang Ma Demin Cao Yuanlong Pan Yongfei Hu Hua Huang George F.Gao Xuebin Xu Baoli Zhu 2023National Science Review2023,10,3:4
4Characterization of aerosol optical properties, chemical composition and mixing states in the winter season in Shanghai, China显示文摘Physical and chemical properties of ambient aerosols at the single particle level were studied in Shanghai from December 22 to 28,2009.A Cavity-Ring-Down Aerosol Extinction Spectrometer(CRD-AES)and a nephelometer were deployed to measure aerosol light extinction and scattering properties,respectively.An Aerosol Time-of-Flight Mass Spectrometer(ATOFMS)was used to detect single particle sizes and chemical composition.Seven particle types were detected.Air parcels arrived at the sampling site from the vicinity of Shanghai until mid-day of December 25,when they started to originate from North China.The aerosol extinction,scattering,and absorption coefficients all dropped sharply when this cold,clean air arrived.Aerosol particles changed from a highly aged type before this meteorological shift to a relatively fresh type afterwards.The aerosol optical properties were dependent on the wind direction.Aerosols with high extinction coefficient and scattering Angstrom exponent(SAE)were observed when the wind blew from the west and northwest,indicating that they were predominantly fine particles.Nitrate and ammonium correlated most strongly with the change in aerosol optical properties.In the elemental carbon/organic carbon(ECOC)particle type,the diurnal trends of single scattering albedo(SSA)and elemental carbon(EC)signal intensity had a negative correlation.We also found a negative correlation(r=-0.87)between high mass-OC particle number fraction and the SSA in a relatively clean period,suggesting that particulate aromatic components might play an important role in light absorption in urban areas.Yong Tang Yuanlong Huang Ling Li Hong Chen Jianmin Chen Xin Yang Song Gao Deborah S.Gross 2014Journal of Environmental Sciences2014,26,12:3
5Late Cretaceous Transpressional Fault System: A Case Study of the Yishu Fault Belt, Shandong Province, Eastern China显示文摘On the basis of field observations of the structures of three profiles from the Linshu region, deformation characteristics and the tectonic background of the Yishu fault belt in the Late Cretaceous–Early Cenozoic have been discussed in detail.Three structural profiles, whose deformations consist mainly of earlier transpressional faults and later normal faults, were developed for the Mengtuan Formation of the Lower Cretaceous Dasheng Group.Typical positive flower structures, duplex structures, and break-through faults were found in these profiles.On the basis of analyses of the structural deformation and previous geochronological studies, it was concluded that the earlier transpressional faults of the profiles were triggered by the sinistral transpression of the Yishu fault belt in the Late Cretaceous–Early Paleogene, and that the later normal faults, formed during the Late Paleogene–Neogene extension, truncated the earlier transpressional faults.With consideration of the tectonic evolution of the Tan-Lu fault belt and the different drift directions of the Pacific plate since the Cretaceous, we suggest that the major tectonic events of the Late Cretaceous–Neogene in eastern China were mainly controlled by the subduction of the Pacific plate.LI Chunlin WANG Zongxiu WU Qingzi LIU Yongqing GAO Wanli TAN Yuanlong KUANG Hongwei LI Huijun 2015Acta Geologica Sinica(English Edition)2015,89,5:3
6Facile synthesis of colloidal nitrogen-doped titanium carbide sheets with enhanced electrochemical performance显示文摘Heteroatom nitrogen doping in two-dimensional transition metal carbides,known as MXenes,has been considered as a promising strategy for modulating their electronic structure and electrochemical reactivity.While hightemperature annealing in the presence of a nitrogen source has been one popular method to introduce nitrogen,annealing exfoliated multilayered MXenes typically brings about incomplete delamination and the treatment of delaminated monolayer MXenes often leads to irreversible restacking.Here,starting from the typical carbide precursor,we developed an aqueous colloid containing monolayered nitrogen-doped titanium carbide sheets with excellent dispersity and stability.This achievement is critically dependent on the retaining of the hydrophilic surface of host layers during annealing treatment.The successful realization of nitrogen doping into individual MXene monolayers resulted in enhanced electrical conductivity and redox reactivity,for which the sample exhibited excellent capacitive electrochemical performance(586 F/g at a scan rate of 5mV/s)and cycling stability(capacitance retention of 96.2%after 104 cycles at 5 A/g).This paper presents a feasible and simple strategy for designing nitrogen-doped MXenes colloid,the realization of which promises its facile uses in liquid phase engineering techniques toward versatile applications.Tianlun Qiu Guohui Li Yuanlong Shao Kun Jiang Fangfang Zhao Fengxia Geng 2020Carbon Energy2020,2,4:2
7Inhibition of p53 and/or AKT as a new therapeutic approach specifically targeting ALT cancers显示文摘While the majority of all human cancers court teract telomere shortening by expressing telomerase,-15%of all cancers maintain telomere length by a telomerase?independent mechanism known as alternative lengthening of telomeres(ALT).Here,we show that high load of intrinsic DNA damage is present in ALT cancer cells,leading to apoptosis stress by activating p53-independent,but JNK/c-IVIyc-dependent apoptotic pathway.Notably,ALT cells expressing wild-type p53 show much lower apoptosis than p53-deficient ALT cells.Mechanistically,we find that intrinsic DNA damage in ALT cells induces low level of p53 that is insufficient to initiate the transcription of apoptosis-related genes,but is sufficient to stimulate the expression of key components of mTORC2(mTOR and Rictor),which in turn leads to phosphorylation of AKT.Activated AKT(p-AKT)thereby stimulates downstream anti-apoptotic events.Therefore,p53 and AKT are the key factors that suppress sponta?neous apoptosis in ALT cells.Indeed,inhibition of p53 or AKT selectively induces rapid death of ALT cells in vitro,and p53 inhibitor severely suppresses the growth of ALT-cell xenograft tumors in mice.These findings reveal a previously unrecognized function of p53 in antiapoptosis and identify that the inhibition of p53 or AKT has a potential as therapeutics for specifically targeting ALT cancers.Yuanlong Ge Shu Wu Zepeng Zhang Xiaocui Li Feng Li Siyu Yan Haiying Liu Junjiu Huang Yong Zhao 2019Protein & Cell2019,10,11:2

10Another Record: Ocean Warming Continues through 2021 despite La Nina Conditions显示文摘The increased concentration of greenhouse gases in the atmosphere from human activities traps heat within the climate system and increases ocean heat content(OHC). Here, we provide the first analysis of recent OHC changes through 2021 from two international groups. The world ocean, in 2021, was the hottest ever recorded by humans, and the 2021 annual OHC value is even higher than last year’s record value by 14 ± 11 ZJ(1 zetta J = 1021 J) using the IAP/CAS dataset and by16 ± 10 ZJ using NCEI/NOAA dataset. The long-term ocean warming is larger in the Atlantic and Southern Oceans than in other regions and is mainly attributed, via climate model simulations, to an increase in anthropogenic greenhouse gas concentrations. The year-to-year variation of OHC is primarily tied to the El Nino-Southern Oscillation(ENSO). In the seven maritime domains of the Indian, Tropical Atlantic, North Atlantic, Northwest Pacific, North Pacific, Southern oceans,and the Mediterranean Sea, robust warming is observed but with distinct inter-annual to decadal variability. Four out of seven domains showed record-high heat content in 2021. The anomalous global and regional ocean warming established in this study should be incorporated into climate risk assessments, adaptation, and mitigation.Lijing CHENG John ABRAHAM Kevin ETRENBERTH John FASULLO Tim BOYER Michael EMANN Jiang ZHU Fan WANG Ricardo LOCARNINI Yuanlong LI Bin ZHANG Zhetao TAN Fujiang YU Liying WAN Xingrong CHEN Xiangzhou SONG Yulong LIU Franco RESEGHETTI Simona SIMONCELLI Viktor GOURETSKI Gengxin CHEN Alexey MISHONOV Jim REAGAN 2022Advances in Atmospheric Sciences2022,39,3:1

14All-inorganic quantum-dot light-emitting-diodes with vertical nickel oxide nanosheets as hole transport layer显示文摘All-inorganic quantum dot light emitting diodes(QLEDs) have gained great attention as a result of their high stability under oxygen-rich, humid and high current working conditions. In this work, we have fabricated an allinorganic QLED device(FTO/NiO/QDs/AZO/Ag) with sandwich-structure, wherein the inorganic metal oxides thin films of NiO and AZO were employed as hole and electron transport layers, respectively. The porous NiO layer with vertical lamellar nanosheets interconnected microstructure have been directly synthesized on the substrate of conductive FTO glass and increased the wettability of CdSe@ZnS QDs, which result in an enhancement of current transport performance of the QLED.Jiahui Li Yuanlong Shao Xuecheng Chen Hongzhi Wang Yaogang Li Qinghong Zhang 2016Progress in Natural Science:Materials International2016,26,5:1

17Intraseasonal variability of the surface zonal current in the equatorial Indian Ocean:Seasonal differences and causes显示文摘Using observations and numerical simulations,this study examines the intraseasonal variability of the surface zonal current(u ISV)over the equatorial Indian Ocean,highlighting the seasonal and spatial differences,and the causes of the differences.Large-amplitude u ISV occurs in the eastern basin at around 80°–90°E and near the western boundary at 45°–55°E.In the eastern basin,the u ISV is mainly caused by the atmospheric intraseasonal oscillations(ISOs),which explains 91%of the standard deviation of the total u ISV.Further analysis suggests that it takes less than ten days for the intraseasonal zonal wind stress to generate the u ISV through the directly forced Kelvin and Rossby waves.Driven by the stronger zonal wind stress associated with the Indian summer monsoon ISO(MISO),the eastern u ISV in boreal summer(May to October)is about 1.5 times larger than that in boreal winter(November to April).In the western basin,both the atmospheric ISOs and the oceanic internal instabilities contribute substantially to the u ISV,and induce stronger u ISV in boreal summer.Energy budget analysis suggests that the mean flow converts energy to the intraseasonal current mainly through barotropic instabilities.Qingwen Zhong Gengxin Chen Yuanlong Li Qihua Peng Xiaoqing Chu 2022Acta Oceanologica Sinica2022,41,5:1

19Scission of C–O and C–C linkages in lignin over RuRe alloy catalyst显示文摘The performance of lignin depolymerization is basically determined by the interunit C–O and C–C bonds.Numerous C–O bond cleavage strategies have been developed, while the cleavage of C–C bond between the primary aromatic units remains a challenging task due to the high dissociation energy of C–C bond.Herein, a multifunctional Ru Re alloy catalyst was designed, which exhibited exceptional catalytic activity for the cleavage of both C–O and C–C linkages in a broad range of lignin model compounds(β-1, a-5, 5–5,β-O-4, 4-O-5) and two stubborn lignins(kraft lignin and alkaline lignin), affording 97.5% overall yield of monocyclic compounds from model compounds and up to 129% of the maximum theoretical yield of monocyclic products based on C–O bonds cleavage from realistic lignin. Scanning transmission electron microscopy(STEM) characterization showed that Ru Re(1:1) alloy particles with hexagonal close-packed structure were homogeneously dispersed on the support. Quasi-in situ X-ray photoelectron spectroscopy(XPS), and X-ray absorption spectroscopy(XAS) indicate that Ru species were predominantly metallic state, whereas Re species were partially oxidized;meanwhile, there was a strong interaction between Ru and Re, where the electron transfer from Re to Ru was occurred, resulting in great improvement on the capability of C–O and C–C bonds cleavage in lignin conversion.Xinxin Li Yangming Ding Xiaoli Pan Yanan Xing Bo Zhang Xiaoyan Liu Yuanlong Tan Hua Wang Changzhi Li 2022Journal of Energy Chemistry2022,31,4:1
