2Qualitatively and quantitatively assessing the aggregation ability of sludge during aerobic granulation process combined XDLVO theory with physicochemical properties显示文摘Inexact mechanism of aerobic granulation still impedes optimization and application of aerobic granules. In this study, the extended Derjaguin, Landau, Verwey, and Overbeek(XDLVO) theory and physicochemical properties were combined to assess the aggregation ability of sludge during aerobic granulation process qualitatively and quantitatively. Results show that relative hydrophobicity of sludge and polysaccharide content of extracellular polymeric substances(EPS) increased, while electronegativity of sludge decreased during acclimation phase. After 20 days' acclimation, small granules began to form due to high aggregation ability of sludge. Since then, coexisted flocs and granules possessed distinct physicochemical properties during granulation and maturation phase. The relative hydrophobicity decreased while electronegativity increased for flocs, whereas that for granules presented reverse trend. Through analyzing the interaction energy using the XDLVO theory, small granules tended to self-grow rather than self-aggregate or attach of flocs due to poor aggregation ability between flocs and granules during the granulation phase. Besides, remaining flocs were unlikely to self-aggregate owing to poor aggregation ability, low hydrophobicity and high electronegativity.Shasha Yuan Mingming Gao Hui Ma Muhammad Zaheer Afzal Yun-Kun Wang Mingyu Wang Hai Xu Shu-Guang Wang Xin-Hua Wang 2018Journal of Environmental Sciences2018,30,5:4
3Permeability variation characteristics of coal after injecting carbon dioxide into a coal seam显示文摘A theoretical basis for the optimization of carbon dioxide injection parameters and the development of the drainage system can be provided by identifying the permeability change characteristic of coal and rock after injection of carbon dioxide into the coal seam. Sihe, Yuwu, and Changcun mines were used as research sites. Scanning electron microscopy and permeability instruments were used to measure coal properties such as permeability and surface structure of the coal samples at different p H values of carbon dioxide solution and over different timescales. The results show that the reaction between minerals in coal and carbonate solution exhibit positive and negative aspects of permeability-the dissolution reaction between carbonate minerals in coal and acid solution improves the conductivity of coal whilst, on the other hand, the clay minerals in the coal(mainly including montmorillonite, illite and kaolinite) exhibit expansion as a result of ion exchange with the H+in acid solution, which has a negative effect on the permeability of the coal. The permeability of coal samples increased at first and then decreased with immersion time, and when the soaking time is 2–3 months the permeability of the coal reached a maximum. In general, for coals with permeabilities less than 0.2 m D or greater than 2 m D, the effect on the permeability is low; when the permeability of the coal is in the range 0.2–2 m D, the effect on the permeability is highest. Research into permeability change characteristics can provide a theoretical basis for carbon dioxide injection under different reservoir permeability conditions and subsequent drainage.Ni Xiaoming Li Quanzhong Wang Yanbin Gao Shasha 2015International Journal of Mining Science and Technology2015,25,4:2
4Sequential immunizations confer cross-protection against variants of SARS-CoV-2,including Omicron in Rhesus macaques显示文摘Variants of concern(VOCs)like Delta and Omicron,harbor a high number of mutations,which aid these viruses in escaping a majority of known SARS-CoV-2 neutralizing antibodies(NAbs).In this study,Rhesus macaques immunized with 2-dose inactivated vaccines(Coronavac)were boosted with an additional dose of homologous vaccine or an RBD-subunit vaccine,or a bivalent inactivated vaccine(Beta and Delta)to determine the effectiveness of sequential immunization.The booster vaccination significantly enhanced the duration and levels of neutralizing antibody titers against wild-type.Wei Deng Qi Lv Fengdi Li Jiangning Liu Zhiqi Song Feifei Qi Qiang Wei Pin Yu Mingya Liu Shasha Zhou Yaqing Zhang Hong Gao Nan Wang Zijing Jia Kai Gao Jiayi Liu Chong Xiao Haiquan Shang Xiangxi Wang Linlin Bao Chuan Qin 2022Signal Transduction and Targeted Therapy2022,7,5:2
5CO_2 –H_2O–coal interaction of CO_2 storage in coal beds显示文摘In order to study the physical and chemical reaction after CO2 injected into coal beds at different condition.The physical and chemistry reaction among CO2,H2O and coal was studied,and the influence on permeability and porosity of coal beds was carried out.The experimental method was used,so did the basic theory of mineralogy,coal petrology,geochemistry,analytical geochemistry and physical chemistry.In this experiment,the changes of mineral and permeability of coal and water quality were observed through CO2 solution reacting with different coal samples.The differences could be found out by comparing the properties and microcrystalline structure before and after the reaction.There are three results were carried out:First,the content of carbonate in coal beds decreases because of the dissolution reaction between carbonate minerals and CO2 solution,and precipitation is formed by reaction of chlorite and orthoclase.Second,the result that permeability and porosity of coal beds are improved after the reaction is proposed.Third,the initial permeability of different coal samples plays a great role on the reaction,and the improvement of permeability is not obvious in the samples which have too low or too high permeability,and the improvement is good in medium permeability(0.2–3 mD).Gao Shasha Wang Yanbin Jia Lilong Wang Hongjie Yuan Jun Wang Xianghao 2013International Journal of Mining Science and Technology2013,23,4:2
6Non-metallic electronic regulation in CuCo oxy-/thio-spinel as advanced oxygen evolution electrocatalysts显示文摘Developing cost-effective and high-performance oxygen evolution reaction(OER)electrocatalysts has become the intense research on pursuing emerging renewable energy conversion,in which exploring and investigating the intrinsic nature of efficient and stable Cu Co spinel catalysts toward OER in alkaline media is highly desirable.Herein,Cu1–xCo2+xO4oxy-spinel nanoflakes are fabricated by a facile hydrothermal method with the oxidation of ammonia water.In the same condition,Cu1–xCo2+xS4thio-spinel nanospheres are formed without oxidation.In OER process,the as-obtained Cu1–xCo2+xO4nanoflakes and Cu1–xCo2+xS4nanospheres possess the anodic overpotential of 267 and 297 m V in alkaline media to drive the current density of 10 m A/cm^2,respectively,outperforming the state-of-the-art noble metal catalyst of RuO2.X-ray photoelectron spectroscopy analysis exhibits the higher ratio value of Co(Ⅲ)/Co(Ⅱ)in Cu1–xCo2+xO4than that in Cu1–xCo2+xS4,suggesting that the stronglyelectronegative oxygen efficiently predominates in regulating valence states of Co active sites in spinel structures.Remarkably,density functional theory simulation further reveals that the increased valence state of Co could accelerate the electron exchange between catalysts and oxygen adsorbates during electrocatalysis,thus contributing to the higher OER activity of Cu1–xCo2+xO4catalysts.This work provides deep insight regarding the significance of non-metal element(O and S)in Cu Co spinel structure catalysts,as well as presents a promising approach to exploit higher performance and grasp the mechanism of various non-noblemetal spinel catalysts for water oxidation.Huan Yang Shuai Gao Dewei Rao Chaonan Zhang Xuecheng Zhou Shaokang Yang Jingjing Ye Shasha Yang Feili Lai Xiaohong Yan 2021Science China Chemistry2021,64,1:1
7Asymmetric interfaces and high-TC ferromagnetic phase in La_(0.67)Ca_(0.33)MnO_(3)/SrRuO_(3)superlattices显示文摘Interfacial magnetism in functional oxide heterostructures not only exhibits intriguing physical phenomena but also implies great potential for device applications.In these systems,interfacial structural and electronic reconstructions are essential for improving the stability and tunability of the magnetic properties.In this work,we constructed ultra-thinLa_(0.67)Ca_(0.33)MnO_(3)/SrRuO_(3)(SRO)layers into superlattices,which exhibited a robust ferromagnetic phase.The high Curie temperature(TC)reaches 291 K,more than 30 K higher than that of bulk LCMO.We found that the LCMO/SRO superlattices consisted of atomically-sharp and asymmetric heterointerfaces.Such a unique interface structure can trigger a sizable charge transfer as well as a ferroelectric-like polar distortion.These two interfacial effects cooperatively stabilized the high-T_(C)ferromagnetic phase.Our results could pave a promising approach towards effective control of interfacial magnetism and new designs of oxide-based spintronic devices.Lili Qu Da Lan Liang Si Chao Ma Shasha Wang Liqiang Xu Kexuan Zhang Feng Jin Zixun Zhang Enda Hua Binbin Chen Guanyin Gao Feng Chen Haifeng Du Karsten Held Lingfei Wang Wenbin Wu 2021Nano Research2021,14,10:1

10Changes in plasma calcitonin gene-related peptide and serum neuron specific enolase in rats with acute cerebral ischemia after low-frequency electrical stimulation with different waveforms and intensities显示文摘Following acute cerebral ischemia in rats,plasma calcitonin gene-related peptide decreased and the level of serum neuron specific enolase and the volume of the infarction increased.Square-wave and triangular-wave electrical stimulation with low or high intensities could increase the plasma calcitonin gene-related peptide,decrease the serum neuron specific enolase and reduce the infarction volume in the brain in rats with cerebral ischemia.There was no significant difference between different wave forms and intensities.The experimental findings indicate that low-frequency electrical stimulation with varying waveforms and intensities can treat acute cerebral ischemia in rats.Qiang Gao Yonghong Yang Shasha Li Jing He Chengqi He 2011Neural Regeneration Research2011,6,28:1

12Long-term fertilization and residue return affect soil stoichiometry characteristics and labile soil organic matter fractions显示文摘Ecological stoichiometry provides the possibility for linking microbial dynamics with soil carbon(C),nitrogen(N),and phosphorus(P)metabolisms in response to agricultural nutrient management.To determine the roles of fertilization and residue return with respect to ecological stoichiometry,we collected soil samples from a 30-year field experiment on residue return(maize straw)at rates of 0,2.5,and 5.0 Mg ha^-1 in combination with 8 fertilization treatments:no fertilizer(F0),N fertilizer,P fertilizer,potassium(K)fertilizer,N and P(NP)fertilizers,N and K(NK)fertilizers,P and K(PK)fertilizers,and N,P,and K(NPK)fertilizers.We measured soil organic C(SOC),total N and P,microbial biomass C,N,and P,water-soluble organic C and N,KMnO4-oxidizabIe C(KMnO4-C),and carbon management index(CMI).Compared with the control(F0 treatment without residue return),fertilization and residue return significantly increased the KMn〇4-C content and CMI.Furthermore,compared with the control,residue return significantly increased the SOC content.Moreover,the NPK treatment with residue return at 5.0 Mg ha^-1 significantly enhanced the C:N,C:P,and N:P ratios in the soil,whereas it significantly decreased the C:N and C:P ratios in soil microbial biomass.Therefore,NPK fertilizer application combined with residue return at 5.0 Mg ha^-1 could enhance the SOC content through the stoichiometric plasticity of microorganisms.Residue return and fertilization increased the soil C pools by directly modifying the microbial stoichiometry of the biomass that was C limited.Shasha LUO Qiang GAO Shaojie WANG Lei TIAN Qi ZHOU Xiujun LI Chunjie TIAN 2020Pedosphere2020,30,5:1
13Neither Fluorocarbons nor Silicones:Hydrocarbon-Based Water-Borne Healable Supramolecular Elastomer with Unprecedent Dual Resistance to Water and Organic Solvents显示文摘Except for fluorocarbons and silicones,few artificial materials display both water and organic solvent resistance.Herein,we report an artificial hydrocarbonbased supramolecular elastomer that displays unprecedented dual resistance to both water and organic solvents.This elastomer is formed in water with two water soluble components,folic acid(FA)and branched poly(ethylene imine)(b-PEI).The hydrogen bonding between the two components occurs immediately,which further promotes the hydrogen bonding between the FA,yielding folate quartets and theirπ-πstacking.These multiple noncovalent interactions work synergistically,leading to a hydrophobic,transparent,stretchable,healable,notchinsensitive,and recyclable elastomer that resists both water and organic solvents.The elastomer remains intact after storage in high humidity and organic solvents for months.Films generated by stretching the elastomer are very hydrophobic,and the contact angle of water on the elastomer is up to 112.3°.The damaged elastomers also exhibit water-assisted healable behavior.This work discloses a new paradigm of material synthesis that can inspire the fabrication of robust nonfluorocarbon and silicone-based materials with green strategies.Shuitao Gao Shasha Jiang Jinwan Qi Tongyue Wu Wenkai Wang Zhijie Liu Bin Zhang Jianbin Huang Yun Yan 2022CCS Chemistry2022,4,12:0
14A leap by the rise of solid-state electrolytes for Li-air batteries显示文摘Li-air batteries have attracted extensive attention because of their ultrahigh theoretical energy density. However, the potential safety hazard of flammable organic liquid electrolytes hinders their practical applications. Replacing liquid electrolytes with solidstate electrolytes(SSEs) is expected to fundamentally overcome the safety issues. In this work, we focus on the development and challenge of solid-state Li-air batteries(SSLABs). The rise of different types of SSEs, interfacial compatibility and verifiability in SSLABs are presented. The corresponding strategies and prospects of SSLABs are also proposed. In particular, combining machine learning method with experiment and in situ(or operando)techniques is imperative to accelerate the development of SSLABs.Kecheng Pan Minghui Li Weicheng Wang Shuochao Xing Yaying Dou Shasha Gao Zhang Zhang Zhen Zhou 2023Green Energy & Environment2023,8,4:0
15Enhancement of visible-light-driven oxidative amine coupling under aerobic and anaerobic conditions by photocatalyst with spatial separation of photoinduced charge carriers显示文摘Spatial separation of oxidation/reduction cocatalyst is an effective means to improve the efficiency of charge separation in photocatalytic reaction systems.Herein,a yolk-shell Pd@NH_(2)-UiO-66@Cu_(2)O heterojunction was designed and synthesized by integration of electron collector Pd and hole collector Cu_(2)O inside and outside of a photoactive metal-organic framework(MOF)NH_(2)-UiO-66,respectively.The obtained Pd@NH_(2)-UiO-66@Cu_(2)O heterojunction effectively inhibits the electron and hole recombination through the photo-induced electrons and holes flow inward and outward of the composite,and promotes the reduction and oxidation abilities for the oxidative coupling of benzylamine to imines.Compared with Pd/NH_(2)-UiO-66@Cu_(2)O,Pd@NH_(2)-UiO-66,and Pd/NH_(2)-UiO-66,Pd@NH_(2)-UiO-66@Cu_(2)O exhibits the highest photocatalytic activity.More importantly,Pd@NH_(2)-UiO-66@Cu_(2)O shows a conversion rate of benzylamine up to 99%either by oxidation under aerobic conditions or by strong adsorption of H atom(Hads)under anaerobic conditions.In addition,the catalyst shows good stability and can be recycled at least ten times.This work provides useful guidance on construction of MOFs-based composites with spatially separated photoinduced charge carriers to realize efficient oxidation coupling of benzylamine in both aerobic and anaerobic conditions.Shasha Wang Kuan Gao Yang Cui Shuwen Li Heyao Zhang Bin Zhang Jie Wu Hongwei Hou Shuangquan Zang 2023Nano Research2023,16,4:0
16A zincophilic molecular brush for a dendrite-free,corrosionresistant,zinc metal anode with a long life cycle显示文摘Zinc-based aqueous rechargeable batteries have attracted extensive attention due to their low cost,safety,and environmental friendliness.However,dendrite growth and hydrogen evolution of Zn anodes limit their large-scale application.A new strategy to produce a polyacrylamide/reduced graphene oxide(PAM@rGO)molecular nanobrush coating and control Zn electrolyte interface engineering is proposed for use in highly reversible Zn plating/stripping.Hydrogen evolution is inhibited,and Zn deposition is consolidated using the rich zincophilic functional groups of the branched polyacrylamide chain and the high conductivity of rGO.Due to the synergistic effects of corrosion resistance and dendrite-free growth,PAM@rGO/Zn provides prolonged and reversible Zn plating/stripping.Density functional theory(DFT)calculations expand on homogenized nucleation.The PAM@rGO/Zn||activated carbon(AC)capacitor exhibits long cyclic stability,fast ion transfer,and minimal interfacial impedance.This study provides experimental and theoretical bases for the structural design of Zn anode.Penggao Liu Jia Guo Xinyue Chen Ting Wang Yanping Huang Shasha Gao Tao Wang Dongling Wu Kaiyu Liu 2024Nano Research2024,17,1:0
17Analyzing and relieving the thermal issues caused by fabrication details of a deuterium cryogenic target显示文摘In inertial confinement fusion experiments,fuel quality is determined mainly by the thermal environment of the capsule in the layering procedure.Owing to the absence of a radial thermal gradient,formed deuterium–deuterium(DD)ice shells in the capsule are thermally instable.To obtain a solid DD layer with good quality and long lifetime,stringent demands must be placed on the thermal performance of cryogenic targets.In DD cryogenic target preparation,two issues arise,even after the capsule’s temperature uniformity has been improved by the use of thick aluminized films.The first is the inconsistent ice shape,which is related to the capsule’s thermal field.In this article,some typical fabrication details are investigated,including adhesive penetration during assembly,the presence of the fill tube,the optical properties of the hohlraum and film surfaces,the jacket–hohlraum connection,deviations in capsule location,and asymmetrical contact at the arm–jacket interfaces.Detailed comparisons of the thermal effects of these factors provide guidance for target optimization.The second issue is the instability of seeding crystals in the fill tube due to unsteadiness of the direction of the thermal gradient in the fill tube assembly.An additional thermal controller is proposed,analyzed,and optimized to provide robust controllability of tube temperature.The analysis results and optimization methods presented in this article should not only help in dealing with thermal issues associated with DD cryogenic targets,but also provide important references for engineering design of other cryogenic targets.Hong Yang Shasha Gao Baibin Jiang Jun Xie Juxi Liang Xiaobo Qi Kai Wang Chaoyou Tao Fei Dai Wei Lin Juan Zhang 2021Matter and Radiation at Extremes2021,6,5:0
18Effects of cervical low-frequency electrical stimulation with various waveforms and densities on body mass,liver and kidney function,and death rate in ischemic stroke rats显示文摘Low-frequency electrical stimulation has resulted in favorable effects in the treatment of post-stroke dysphagia.However,the safety of cervical low-frequency electrical stimulation remains unclear because of numerous nerves and blood vessels in the neck.In the present study,rats with ischemic stroke underwent low-frequency electrical stimulation,and systemic and local effects of electrical stimulation at different densities and waveforms were investigated.Electrical stimulation resulted in no significant effects on body mass,liver or kidney function,or mortality rate.In addition,no significant adverse reaction was observed,despite overly high intensity of low-frequency electrical stimulation,which induced laryngismus,results from the present study suggested that it is safe to stimulate the neck with a low-frequency electricity under certain intensities.Yonghong Yang Chengqi He Lin Yang Qiang Gao Shasha Li Jing He 2011Neural Regeneration Research2011,6,4:0
19Unsaturated bi-heterometal clusters in metal-vacancy sites of 2D MoS2 for efficient hydrogen evolution显示文摘The valence states and coordination structures of doped heterometal atoms in two-dimensional(2D)nanomaterials lack predictable regulation strategies.Hence,a robust method is proposed to form unsaturated heteroatom clusters via the metal-vacancy restraint mechanism,which can precisely regulate the bonding and valence state of heterometal atoms doped in 2D molybdenum disulfide.The unsaturated valence state of heterometal Pt and Ru cluster atoms form a spatial coordination structure with Pt–S and Ru–O–S as catalytically active sites.Among them,the strong binding energy of negatively charged suspended S and O sites for H+,as well as the weak adsorption of positively charged unsaturated heterometal atoms for H*,reduces the energy barrier of the hydrogen evolution reaction proved by theoretical calculation.Whereupon,the electrocatalytic hydrogen evolution performance is markedly improved by the ensemble effect of unsaturated heterometal atoms and highlighted with an overpotential of 84 mV and Tafel slope of 68.5 mV dec^(−1).In brief,this metal vacancy-induced valence state regulation of heterometal can manipulate the coordination structure and catalytic activity of heterometal atoms doped in the 2D atomic lattice but not limited to 2D nanomaterials.Gonglei Shao Jie Xu Shasha Gao Zhang Zhang Song Liu Xu Zhang Zhen Zhou 2024Carbon Energy2024,6,3:0
20Solid-phase molecular self-assembly facilitated supramolecular films with alternative hydrophobic/hydrophilic domains for skin moisture detection显示文摘Human skin moisture is closely related to health and personal care issues.Many creams were developed to claim capable of skin moisturizing.However,people can hardly check their skin moisture status and the moisturizing effect of various creams conveniently,since currently all the skin moisturizing detection rely on large equipment requiring power supply.Herein,we report a power-supply independent supramolecular film that is able to directly report the moisturizing status of the skin.With the strategy of solid-phase molecular self-assembly(SPMSA),the aqueous precipitates formed by commercially available polyelectrolyte and oppositely charged surfactant would transform into a supramolecular film under a mild mechanical pressure,where the hydrophobic surfactant domains bridged by polyelectrolyte merge into hydrophobic mesophases to reduce interfacial energy.The hydrophobic mesophase will greatly retard water diffusion inside the film,so that a humidity gradient is generated as the film is exposed to a humid environment.The film will bend upward automatically in touch with moisture skin,and the bending degree is proportional to the skin moisture status.Therefore,the film can be used as portable smart power-free skin moisture sensor.Jinwan Qi Tongyue Wu Wenkai Wang Hongjun Jin Shuitao Gao Shasha Jiang Jianbin Huang Yun Yan 2022Aggregate2022,3,2:0
