1Preparation and characterization of capric-palmitic-stearic acid ternary eutectic mixture/expanded vermiculite composites as form-stabilized thermal energy storage materials显示文摘In this study, a composite of form-stable phase change materials(FSPCMs) were prepared by the incorporation of a eutectic mixture of capric–palmitic–stearic acid(CA–PA–SA) into expanded vermiculite(EV)via vacuum impregnation. In the composites, CA–PA–SA was utilized as a thermal energy storage material,and EV served as the supporting material. X-ray diffraction and Fourier transform infrared spectroscopy results demonstrated that CA–PA–SA and EV in the composites only undergo physical combination, not a chemical reaction. Scanning electron microscopy images indicated that CA–PA–SA is sufficiently absorbed in the expanded vermiculite porous network. According to differential scanning calorimetry results, the70 wt% CA–PA–SA/EV sample melts at 19.3℃ with a latent heat of 117.6 J/g and solidifies at 17.1℃ with a latent heat of 118.3 J/g. Thermal cycling measurements indicated that FSPCMs exhibit adequate stability even after being subjected to 200 melting–freezing cycles. Furthermore, the thermal conductivity of the composites increased by approximately 49.58% with the addition of 5 wt% of Cu powder. Hence,CA–PA–SA/EV FSPCMs are effective latent heat thermal energy storage building materials.Weiyi Zhang Xiaoguang Zhang Zhaohui Huang Zhaoyu Yin Ruilong Wen Yaoting Huang Xiaowen Wu Xin Min 2018Journal of Materials Science & Technology2018,34,2:8
2Role of sorbent surface functionalities and microporosity in 2,2′,4,4′-tetrabromodiphenyl ether sorption onto biochars显示文摘The study provides insight into the combined effect of sorbent surface functionalities and microporosity on2,2 ′,4,4 ′-tetrabromodiphenyl ether (BDE-47) sorption onto biochars. A series of biochars prepared underdifferent conditionswere used to test their sorption behaviorswith BDE-47. The extents of sorption behaviorswere parameterized in terms of the single-point adsorption equilibrium constant (Koc ) at three equilibrium concentration (C e ) levels (0.001Sw (solubility), 0.005Sw , and 0.05Sw )whichwasdetermined using the Freundlich model. To elucidate the concentration-dependentdominant mechanisms for BDE-47 sorption onto biochars, K ocwas correlatedwith four major parameters using multiple parameter linear analysis accompaniedwith significance testing. The results indicated that at low concentration (Ce = 0.001Sw ), the surface microporosity term,which represented a pore-filling mechanism, contributed significantly to this relationship,while as concentrationwas increased to higher levels, surface functionality related to surface adsorption began to take thedominant role,whichwas further confirmed by the results of Polanyi-based modeling. Given the above results, adual mode model based on Dubinin-Radushkevich andde Boer-Zwikker equationswas adopted to quantitatively assess the changes of significance of surface adsorption aswell as that of pore fillingwith sorption processdevelopment. In addition, UV spectra of four typical aromatic compoundswhich represented the key structural fragments of biochars before and after interactionswith BDE-47were analyzed todetermine the active functional groups and supply complementary evidence for thedominant interaction force for surface adsorption, based onwhich π-π electron-donor-acceptor interactionwas proposed to contribute greatly to surface adsorption.Jia Xin Ruilong Liu Hubo Fan Meilan Wang Miao Li Xiang Liu 2013Journal of Environmental Sciences2013,25,7:6
3Effect of Aluminum Tri-polyphosphate on Corrosion Behavior of Reinforcing Steel in Seawater Prepared Coral Concrete显示文摘Atri-polyphosphate was used as a corrosion inhibitor in the seawater prepared coral concrete, and its influence on the corrosion behavior of carbon steel, 304 austenitic stainless steel, and 2205 duplex stainless steel was studied by the open-circuit potential, electrochemical impedance spectroscopy, and potentiodynamic polarization, respectively. The results reveal that the corrosion potential and impedance of the reinforcing steel increase, while the corrosion current density decreases with the content of aluminum tripolyphosphate in the coral concrete. A low content of the corrosion inhibitor significantly retards the corrosion of the two stainless steels, but it cannot effectively inhibit the corrosion of the carbon steel in the coral concrete.In general, the carbon steel is unsuitable for the coral concrete for its poor corrosion resistance. In contrast,the stainless steels, especially the 2205 duplex stainless steel, shows an excellent anti-corrosion property in the seawater prepared coral concrete containing a certain amount of inhibitor, which is one of the satisfactory candidate methods to build the long-life coral concrete constructions.冯兴国 ZHANG Leyuan ZHANG Jing 卢向雨 XU Yiwen ZHANG Xiangying SHI Ruilong CHEN Da 2019Journal of Wuhan University of Technology(Materials Science)2019,34,4:4

5One-step Condensation/copolymerization of VTES and DVB for Self-assembly Bionic Superhydrophobic Surface Coating and Study on Oil-water Separation显示文摘Mimicry of nature drives the development of bionic materials.Bionic superhydrophobic materials are a kind of high-efficiency materials to handle oil spills and water pollution.However,the stability of surface coatings of the superhydrophobic materials remains a challenge.Herein,a new category of self-assembly bionic superhydrophobic surface coating was prepared via one-step condensation/copolymerization of vinyltriethoxysilane(VTES)and divinylbenzene(DVB),which realized the close combination of covalent bonds between organic(e.g.DVB)and inorganic matter(e.g.VTES),and avoided the swelling of polydivinylbenzene(PDVB)in the process of collection of oil from water.This organic-inorganic hybrid polymer could self-assembly deposit on the surface of sponge even other substrates.For example,P(VTES-DVB)-Si0_(2)/MS obtained by assembling P(VTES-DVB)-Si0_(2)on the surface of Melamine Sponge(MS)exhibited superhydrophobicity with a Water Contact Angle(WCA)of 157.3,the optimal adsorption capacity of 77 g g 136 g g-1 for diverse oils,and an excellent separation efficiency of 99.3%.Besides,the excellent acid and alkali resistance of P(VTES-DVB)-Si0_(2)/MS suggested the potential value in practical oil-water separation.P(VTES-DVB)-Si0_(2)showed the outstanding hydrophobic performance by using as coating on different substrates.This work provided a new idea about the stable combination of organic and inorganic matter in the surface modification.Ruilong Zhang Zhiping Zhou Yi Wang Xiaohui Dai Li Chen Jiangdong Dai 2021Journal of Bionic Engineering2021,18,3:3
6Polysaccharide-based nanomedicines for cancer immunotherapy:A review显示文摘Cancer immunotherapy is an effective antitumor approach through activating immune systems to eradicate tumors by immunotherapeutics.However,direct administration of“naked”immunotherapeutic agents(such as nucleic acids,cytokines,adjuvants or antigens without delivery vehicles)often results in:(1)an unsatisfactory efficacy due to suboptimal pharmacokinetics;(2)strong toxic and side effects due to low targeting(or off-target)efficiency.To overcome these shortcomings,a series of polysaccharide-based nanoparticles have been developed to carry immunotherapeutics to enhance antitumor immune responses with reduced toxicity and side effects.Polysaccharides are a family of natural polymers that hold unique physicochemical and biological properties,as they could interact with immune system to stimulate an enhanced immune response.Their structures offer versatility in synthesizing multifunctional nanocomposites,which could be chemically modified to achieve high stability and bioavailability for delivering therapeutics into tumor tissues.This review aims to highlight recent advances in polysaccharide-based nanomedicines for cancer immunotherapy and propose new perspectives on the use of polysaccharide-based immunotherapeutics.Yujun Zeng Yufan Xiang Ruilong Sheng Helena Tomás João Rodrigues Zhongwei Gu Hu Zhang Qiyong Gong Kui Luo 2021Bioactive Materials2021,6,10:3
7Anti-corruption, marketisation and firm behaviours: evidence from firm innovation in China显示文摘China has launched an anti-corruption campaign since theEighteenth CPC National Congress, which has exerted widespreadinfluences on Chinese politics and economy. This paper examinesthe effect of the anti-corruption initiative on firm behaviours fromthe perspective of research and development (R&D) investments. Itshows that pursuing political connections and improving innovation are two mutually exclusive alternatives for firm growth inChina. The anti-corruption campaign raises the cost of seeking forpolitical bond and strengthens the incentive for firm innovation.After anti-corruption policies and regulations were issued, R&Dexpenditure in politically connected firms increases significantly;the anti-corruption initiative has positive effects on firm innovation.Further research shows that the effects vary with different types offirms. For state-owned enterprises (SOEs), the anti-corruptioninitiative only increases the R&D investments of firms with seniorexecutives who used to serve in the government;while for nonstate-owned enterprises (non-SOEs), this campaign has all-aroundpositive effects on their R&D investments. In the meantime, a heterogeneity at the provincial level is observed: R&D investments offirms with political connections increase more significantly in provinces with more intense anti-corruption efforts. Finally, marketisation also has a role to play. For regions with a more developedmarket economy, anti-corruption increases the innovation of firmswith political connections;whereas in regions with a less developed market economy, this effect is insignificant. This paper provides evidence for the opinion that anti-corruption is favourable toeconomic growth in China. To solve the endogeneity problem, ituses data obtained from the anti-corruption policy experimentsince the Eighteenth CPC National Congress and the difference-indifferences (DID) method to further test the hypotheses.Li Dang Ruilong Yang 2016Economic and Political Studies2016,4,1:1
8Single-wavelength-excited fluorogenic nanoprobe for accurate realtime ratiometric analysis of broad pH fluctuations in mitophagy显示文摘Mitophagy has a critical role in maintaining cellular homeostasis through acidic lysosomes engulfing excess or impaired mitochondria,thereby pH fluctuation is one of the most significant indicators for tracking mitophagy.Then such precise pH tracking demands the fluorogenic probe that has tailored contemporaneous features,including mitochondrial-specificity,excellent biocompatibility,wide pH-sensitive range of 8.0–4.0,and especially quantitative ability.However,available molecular probes cannot simultaneously meet all the requirements since it is extremely difficult to integrate multiple functionalities into a single molecule.To fully address this issue,we herein integrate two fluorogenic pH sensitive units,a mitochondria-specific block,cellpenetrating facilitator,and biocompatible segments into an elegant silica nano scaffold,which greatly ensures the applicability for real-time tracking of pH fluctuations in mitophagy.Most significantly,at a single wavelength excitation,the integrated pHsensitive units have spectra-distinguishable fluorescence towards alkaline and acidic pH in a broad range that covers mitochondrial and lysosomal pH,thus enabling a ratiometric analysis of pH variations during the whole mitophagy.This work also provides constructive insights into the fabrication of advanced fluorescent nanoprobes for diverse biomedical applications.Xin Zhang Juan Chen Jiwen Hu Anna du Rietz Xiongyu Wu Ruilong Zhang Zhongping Zhang Kajsa Uvdal Zhangjun Hu 2022Nano Research2022,15,7:1

12Propagation properties of foreshock cavitons: Cluster observations显示文摘Foreshock cavitons are transient phenomena observed in the terrestrial foreshock region.They are characterized by a simultaneous depression of magnetic field magnitude and plasma density,which are bounded with enhancements of these two parameters and surrounded by ultralow frequency(ULF)waves.Previous studies focused on the interplanetary magnetic field(IMF)conditions,solar wind(SW)conditions,and the growth of the foreshock waves related to the generation of foreshock cavitons.Previously,a multipoint spacecraft analysis method using Cluster data was applied to analyze only two foreshock cavitons,and this method did not consider uncertainties.In this study,multipoint spacecraft analysis methods,including the timing method,the minimum directional derivative(MDD)method,and the spatiotemporal difference(STD)method are applied to determine the velocity in both spacecraft and solar wind frames.The propagation properties show good agreement with previous results from simulations and observations that most cavitons move sunward in the solar wind frame,with the velocities larger than the Alfvén speed.The propagation properties of foreshock cavitons support the formation mechanism of cavitons in previous simulations,which suggested that cavitons are formed due to the nonlinear evolution of compressive ULF waves.We find that there is clear decreasing trend between the size of cavitons and their velocity in the solar wind frame.In addition,the timing method considering errors has been applied to study the evolution properties by comparing the velocities with errors of the leading and trailing edges,and we identify three stable cavitons and one contracting caviton,which has not been studied before.Most cavitons should remain stable when they travel toward the Earth’s bow shock.The relationship between the size of foreshock cavitons and their distance from the bow shock is also discussed.WANG MengMeng YAO ShuTao SHI QuanQi ZHANG Hui TIAN AnMin DEGELING Alexander William ZHANG Shuai GUO RuiLong SUN WeiJie LIU Ji BAI ShiChen SHEN XiaoChen ZHU XiaoQiong FU SuiYan PU ZuYin 2020Science China(Technological Sciences)2020,63,1:1
13Effects of Deformation Modes on Texture Evolution during Hot Working of Al-Zn-Mg-Cu-Zr Alloy显示文摘Deformation modes have strong effects on deformation textures and subsequent annealing textures during hot working of metals. Micro-textures and macro-textures during hot axisymmetric and planar compressive deformation and subsequent annealing processes of Al-Zn-Mg-Cu-Zr alloy were investigated by EBSD and XRD respectively. The EBSD testing indicated that for the axisymmetric compressive deformation, Brass along the α-fiber and Goss present in the sample deformed at 350 ℃, Rotated-Cube was present and Brass transformed to Goss along α-fiber after annealing; Rotated-Cube appeared only in the deformation at 420 ℃, which decreased and Brass appeared after annealing. For the planar compressive deformation, Rotated-Cube and Brass aligned to α and β fibers present in the deformation at 350 ℃, Rotated-Cube texture transformed to Brass along the α-fiber after annealing; Rotated-Cube and Brass were present in the deformation at 420 ℃, and the Rotated-Cube was enhanced and Brass transformed to Goss after annealing. Shearing textures dominated on the surface of the specimen. XRD testing showed that Rotated-Cube and a few Goss dominated in the thickplates formed by upsetting and drawing, which transformed to Cube after annealing; However, Brass and Cube textures present in the thick-plates formed by rolling besides Rotated-Cube and Goss textures, which remained in the plates after annealing.赵晓东 LU Ruilong LIN Jinbao 陈慧琴 2016Journal of Wuhan University of Technology(Materials Science)2016,31,3:1

15Robust,fluorine-free and superhydrophobic composite melamine sponge modified with dual silanized SiO_(2) microspheres for oil-water separation显示文摘Massive oily wastewater discharged from industrial production and human daily life have been an urgent environmental and ecological challenge.Superhydrophobic materials have attracted tremendous attention due to their unique properties and potential applications in the treatment of wastewater.In this study,a novel superhydrophobic/superoleophilic composite melamine sponge modified with dual silanized SiO_(2) microspheres was fabricated simply by a two-step sol-gel method using vinyltriethoxysilane and hexadecyltrimethoxysilane as functional agent,which exhibited a water contact angle of 153.2°and a water sliding contact angle of 4.8°.Furthermore,the composite sponge showed the excellent oil adsorption performance and the compressive elasticity reaching up to 130 g·g^(-1) of dichloromethane and 33.1 kPa of compressive stress.It was worth noting that the composite sponge presented the excellent separation efficiency(up to 99.5%)in the processes of continuous oil/water separation.The robust superhydrophobic composite melamine sponge provided the possibility with the practical application for oil-water separation.Ruilong Zhang Zhiping Zhou Wenna Ge Yi Lu Tianshu Liu Wenming Yang Jiangdong Dai 2021Chinese Journal of Chemical Engineering2021,34,5:1
