| 1 | Visible-light-driven Ag/Ag_3PO_4-based plasmonic photocatalysts:Enhanced photocatalytic performance by hybridization with graphene oxide显示文摘An efficient visible-light-driven plasmonic photocatalyst with regard to graphene oxide(GO) hybridized Ag/Ag3PO4(Ag/Ag3PO4/GO) nanostructures has been facilely synthesized via a deposition-precipitation method.The synthesized nanostructures have been characterized by means of scanning electron microscopy(SEM),energy-dispersive X-ray spectroscopy(EDX),X-ray diffraction(XRD),UV-vis spectra,Fourier transform infrared spectra(FT-IR),X-ray photoelectron spectroscopy(XPS),and Raman spectra.It has been disclosed that compared with the bare Ag/Ag3PO4 nanospecies,the GO hybridized nanostructures display enhanced photocatalytic activity for the photodegradation of methyl orange pollutant under visible-light irradiation.It is suggested that the reinforced charge transfer and the suppressed recombination of electron-hole pairs in Ag/Ag3PO4 /GO,the smaller size of Ag/Ag3PO4 nanospecies in Ag/Ag3PO4/GO,all of which are the consequences of the hybridization of GO,are responsible for the enhanced photocatalytic performance.The investigation might open up new opportunities to obtain highly efficient Ag3PO4-based visible-light-driven plasmonic photocatalyst for the photodegradation of organic pollutants. | ZHU MingShan CHEN PengLei LIU MingHua | 2013 | Chinese Science Bulletin2013，58，1： | 10 |
| 2 | Glycerol carbonate synthesis from glycerol and dimethyl carbonate using guanidine ionic liquids显示文摘A large number of surplus glycerol from the biodiesel production can be used as renewable feedstock to produce glycerol carbonate. In this paper, a series of guanidine-based ionic liquids were synthesized to catalyze the transesterification of glycerol and dimethyl carbonate. The tunable basicity and the anion–cation cooperative effect were responsible for the obtained results. The [TMG][TFE] showed the best activity turnover frequency(TOF)of 1754.0 h^(-1), glycerol(GL) conversion of 91.8%, glycerol carbonate(GC) selectivity of 95.5%) at 80 °C with 0.1 mol% catalyst for 30 min. The reaction mechanism of the transesterification was also proposed. | Xingxing Wang Peng Zhang Penglei Cui Weiguo Cheng Suojiang Zhang | 2017 | Chinese Journal of Chemical Engineering2017，25，9： | 5 |
| 3 | A 1-dodecanethiol-based phase transfer protocol for the highly efficient extraction of noble metal ions from aqueous phase显示文摘A 1-dodecanethiol-based phase-transfer protocol is developed for the extraction of noble metal ions from aqueous solution to a hydrocarbon phase, which calls for first mixing the aqueous metal ion solution with an ethanolic solution of 1-dodecanethiol, and then extracting the coordination compounds formed between noble metal ions and1-dodecanethiol into a non-polar organic solvent. A number of characterization techniques,including inductively coupled plasma atomic emission spectroscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis demonstrate that this protocol could be applied to extract a wide variety of noble metal ions from water to dichloromethane with an efficiency of > 96%, and has high selectivity for the separation of the noble metal ions from other transition metals. It is therefore an attractive alternative for the extraction of noble metals from water, soil, or waste printed circuit boards. | Dong Chen Penglei Cui Hongbin Cao Jun Yang | 2015 | Journal of Environmental Sciences2015，27，3： | 5 |

| 5 | Synthesis of monolithic carbon aerogels with high mechanical strength via ambient pressure drying without solvent exchange显示文摘A simple,fast and cost-effective method for monolithic carbon aerogels(CAs) preparation was proposed through sol-gel polycondensation of resorcinol with fo rmaldehyde in a basic aqueous solution followed by ambient pressure drying without solvent exchange,and carbonization.The microstructure and network strength of CAs were tailored by adju sting the catalyst concentration([resorcinol]/[sodium carbonate] in the range of 300-2000),water content([deionized water]/[resorcinol] equals to 17 and 24,respectively),and gelation temperature(Tgel in the range of 30-90℃).Resultantly,the CAs with a wide range of density(0.30-1.13 g/cm3),high specific surface area(465-616 m2/g),high compressive strength(6.5-147.4 MPa)and low thermal conductivity(0.065-0.120 W·m-1 K-1) were obtained in this work.Moreover,the largesized CAs(100×100×20 mm3) can also be prepared by this method since the formed robust skeleton network can resist shrinkage/collapse of pore structure and prevent cracking during drying.The improved mechanical strength and monolithic forming abilities could be mainly attributed to the uniform arrangement of carbon particles and pores,fine particle size,abundant network structure and enhanced particle neck. | Zhi Yang Jian Li Xiaojing Xu Shengyang Pang Chenglong Hu Penglei Guo Sufang Tang Hui-Ming Cheng | 2020 | Journal of Materials Science & Technology2020，47，15： | 4 |
| 6 | PIP5k1β controls bone homeostasis through modulating both osteoclast and osteoblast differentiation显示文摘PIP5k1βis crucial to the generation of phosphotidylinosotol(4,5)P2.PIP5k1βparticipates in numerous cellular activities,such as B cell and platelet activation,cell phagocytosis and endocytosis,cell apoptosis,and cytoskeletal organization.In the present work,we aimed to examine the function of PIP5k1βin osteoclastogenesis and osteogenesis to provide promising strategies for osteoporosis prevention and treatment.We discovered that PIP5k1β deletion in mice resulted in obvious bone loss and that PIP5k1β was highly expressed during both osteoclast and osteoblast differentiation.Deletion of the gene was found to enhance the proliferation and migration of bone marrow-derived macrophage-like cells to promote osteoclast differentiation.PIP5k1β-/-osteoclasts exhibited normal cytoskeleton architecture but stronger resorption activity.PIP5kip deficiency also promoted activation of mitogen-activated kinase and Akt signaling,enhanced TRAF6 and c-Fos expression,facilitated the expression and nuclear translocation of NFATC1,and upregulated Grb2 expression,thereby accelerating osteoclast differentiation and function.Finally,PIP5k1β enhanced osteoblast differentiation by upregulating master gene expression through triggering smad1/5/8 signaling.Therefore,PIP5k1βmodulates bone homeostasis and remodeling. | Xiaoying Zhao Penglei Cui Guoli Hu Chuandong Wang Lei Jiang Jingyu Zhao Jiake Xu Xiaoling Zhang | 2020 | Journal of Molecular Cell Biology2020，12，1： | 4 |

| 8 | Heterogeneous nanocomposites consisting of Pt_(3)Co alloy particles and CoP_(2) nanorods towards high-efficiency methanol electro-oxidation显示文摘Heterogeneous nanocomposites comprising chemically distinct constituents are particularly promising in electrocatalysis.We herein report a synthetic strategy that combines the reduction of Pt and Co ionic precursors at an appropriate ratio with the subsequent phosphating at an elevated temperature for forming heterogeneous nanocomposites consisting of quasi-spherical Pt_(3)Co alloy domains and rod-like CoP_(2) domains for high-efficiency methanol electrooxidation.The strong electronic coupling between Pt_(3)Co and CoP_(2) domains in the nanocomposites render the electron density around Pt atoms to decrease,which is favorable for reducing the adsorption of poisoning CO-like intermediates on the catalyst surfaces.Accordingly,the as-prepared heterogeneous Pt_(3)Co–CoP_(2) nanocomposites show good performance for methanol electrooxidation both in acidic and alkaline media.In specific,at a Pt loading of only 6.4%on a common carbon substrate,the mass-based activity of Pt_(3)Co–CoP_(2) nanocomposites in an acidic medium is about 2 and 1.5 times as high as that of commercial Pt/C catalyst(20%mass loading)and home-made Pt_(3)Co alloy nanoparticles(8.0%mass loading),while in the alkaline medium,these values are 3 and 2,respectively. | Niuwa Yang Dong Chen Penglei Cui Tingyu Lu Hui Liu Chaoquan Hu Lin Xu Jun Yang | 2021 | SmartMat2021，2，2： | 3 |
| 9 | Coaxial Twin-shaft Magnetic Fluid Seals Applied in Vacuum Wafer-Handling Robot显示文摘Compared with traditional mechanical seals,magnetic fluid seals have unique characters of high airtightness,minimal friction torque requirements,pollution-free and long life-span,widely used in vacuum robots.With the rapid development of Integrate Circuit(IC),there is a stringent requirement for sealing wafer-handling robots when working in a vacuum environment.The parameters of magnetic fluid seals structure is very important in the vacuum robot design.This paper gives a magnetic fluid seal device for the robot.Firstly,the seal differential pressure formulas of magnetic fluid seal are deduced according to the theory of ferrohydrodynamics,which indicate that the magnetic field gradient in the sealing gap determines the seal capacity of magnetic fluid seal.Secondly,the magnetic analysis model of twin-shaft magnetic fluid seals structure is established.By analyzing the magnetic field distribution of dual magnetic fluid seal,the optimal value ranges of important parameters,including parameters of the permanent magnetic ring,the magnetic pole tooth,the outer shaft,the outer shaft sleeve and the axial relative position of two permanent magnetic rings,which affect the seal differential pressure,are obtained.A wafer-handling robot equipped with coaxial twin-shaft magnetic fluid rotary seals and bellows seal is devised and an optimized twin-shaft magnetic fluid seals experimental platform is built.Test result shows that when the speed of the two rotational shafts ranges from 0-500 r/min,the maximum burst pressure is about 0.24 MPa.Magnetic fluid rotary seals can provide satisfactory performance in the application of wafer-handling robot.The proposed coaxial twin-shaft magnetic fluid rotary seal provides the instruction to design high-speed vacuum robot. | CONG Mingt WEN Haiying DU yu DAI Penglei | 2012 | Chinese Journal of Mechanical Engineering2012，25，4： | 2 |
| 10 | Multi-objective optimization for membrane reactor for steam methane reforming heated by molten salt显示文摘A membrane reactor for steam methane reforming heated by molten salt(MS-SMRMR)is studied based on finite time thermodynamics for decreasing carbon emissions and improving hydrogen production rate(HPR).Effects of flow directions of sweep gas and molten salt on MS-SMRMR are researched.Profiles of temperatures,HPR,and local entropy generation rates(EGRs)of MS-SMRMR are analyzed.Hybrid particle swarm optimization algorithm is utilized to obtain the minimum of specific EGR(SEGR),ratio of EGR to HPR.Multi-objective optimization about HPR maximization and EGR minimization is performed by utilizing NSGA-II.The EGR caused by the mass transfer process is the largest among all irreversible processes in the MS-SMRMR.The membrane length should be slightly shorter than the reactor length when the flow direction of sweep gas is different from that of reaction mixture.When flow directions of molten salt and sweep gas are opposite to that of reaction mixture,SEGR is the smallest.Compared with SEGR calculated by utilizing initial parameters,SEGRs after primary,twice and triple optimizations reduce by 1.2%,5.5%and 5.7%,respectively.SEGR can be further decreased by adjusting other operating parameters.Pareto front provides many optimization results,and it contains SEGR minimization.In Pareto front,an optimum decision point is obtained based on decision-making of TOPSIS,and its EGR and HPR,respectively,increase by 7.12%and13.24%,compared with those obtained by using initial parameters.The results have certain theoretical guiding significance for optimization designs of MS-SMRMR. | CHEN LinGen LI PengLei XIA ShaoJun KONG Rui GE YanLin | 2022 | Science China(Technological Sciences)2022，65，6： | 2 |
| 11 | Identification of subsurface damage of 4H-SiC wafers by combining photo-chemical etching and molten-alkali etching显示文摘In this work,we propose to reveal the subsurface damage(SSD)of 4H-SiC wafers by photo-chemical etching and identify the nature of SSD by molten-alkali etching.Under UV illumination,SSD acts as a photoluminescence-black defect.The selective photo-chemical etching reveals SSD as the ridge-like defect.It is found that the ridge-like SSD is still crystalline 4H-SiC with lattice distortion.The molten-KOH etching of the 4H-SiC wafer with ridge-like SSD transforms the ridge-like SSD into groove lines,which are typical features of scratches.This means that the underlying scratches under mechanical stress give rise to the formation of SSD in 4H-SiC wafers.SSD is incorporated into 4H-SiC wafers during the lapping,rather than the chemical mechanical polishing(CMP). | Wenhao Geng Guang Yang Xuqing Zhang Xi Zhang Yazhe Wang Lihui Song Penglei Chen Yiqiang Zhang Xiaodong Pi Deren Yang Rong Wang | 2022 | Journal of Semiconductors2022，43，10： | 2 |
| 12 | Nanoengineered hydrogels as 3D biomimetic extracellular matrix with injectable and sustained delivery capability for cartilage regeneration显示文摘The regeneration of articular cartilage remains a great challenge due to the difficulty in effectively enhancing spontaneous healing.Recently,the combination of implanted stem cells,suitable biomaterials and bioactive molecules has attracted attention for tissue regeneration.In this study,a novel injectable nanocomposite was rationally designed as a sustained release platform for enhanced cartilage regeneration through integration of a chitosan-based hydrogel,articular cartilage stem cells(ACSCs)and mesoporous SiO_(2)nanoparticles loaded with anhydroicaritin(AHI).The biocompatible engineered nanocomposite acting as a novel 3D biomimetic extracellular matrix exhibited a remarkable sustained release effect due to the synergistic regulation of the organic hydrogel framework and mesopore channels of inorganic mSiO_(2)nanoparticles(mSiO_(2)NPs).Histological assessment and biomechanical tests showed that the nanocomposites exhibited superior performance in inducing ACSCs proliferation and differentiation in vitro and promoting extracellular matrix(ECM)production and cartilage regeneration in vivo.Such a novel multifunctional biocompatible platform was demonstrated to significantly enhance cartilage regeneration based on the sustained release of AHI,an efficient bioactive natural small molecule for ACSCs chondrogenesis,within the hybrid matrix of hydrogel and mSiO_(2)NPs.Hence,the injectable nanocomposite holds great promise for use as a 3D biomimetic extracellular matrix for tissue regeneration in clinical diagnostics. | Penglei Cui Panpan Pan Ling Qin Xinluan Wang Xiaodong Chen Yonghui Deng Xiaoling Zhang | 2023 | Bioactive Materials2023，，1： | 2 |
| 13 | Total entropy generation rate minimization configuration of a membrane reactor of methanol synthesis via carbon dioxide hydrogenation显示文摘The total entropy generation rate,internal exergy loss and exergy efficiency of the membrane reactor of methanol synthesis via carbon dioxide hydrogenation are compared,and the results show that the total entropy generation rate minimization is equivalent to the internal exergy loss minimization and the exergy efficiency maximization under the fixed inlet exergy.Therefore,this paper optimizes the membrane reactor with total entropy generation rate minimization as an optimization objective under a fixed methanol production rate.The optimal temperatures curves of exterior walls for three optimal membrane reactors with different boundary conditions are obtained by using optimal control theory and nonlinear programming.The influences of other geometric and operating parameters on optimization results of optimal membrane reactors are analyzed.The results indicate that when inlet temperatures of the reaction mixture and mixture in the permeable tube are unfixed,the optimizing curve of exterior wall temperature makes the total entropy generation rate of membrane reactor reduce by 12.39%compared with the total entropy generation rate of a reference membrane reactor with a linear exterior wall temperature.Decreasing the inlet molar flow rate of sweep gas and gas hourly space velocity and increasing inlet pressure of reaction mixture,the inlet pressure of mixture in the permeable tube and heat transfer coefficients are favorable for decreasing the total entropy generation rate in the membrane reactor.As the porosity of catalyst bed and reactor length increases,the minimum total entropy generation rate decreases first and then increases.From the perspective of engineering application,this paper establishes two membrane reactors(membrane reactor heated by three-stage furnaces of the same length and membrane reactor heated by threestage furnaces of different lengths),respectively.The minimum total entropy generation rates of the two reactors are reduced by11.67%and 11.79%compared with the total entropy generation rate in the reference membrane reactor,respectively.The obtained results are beneficial to the optimal design of energy-efficient membrane reactors. | LI PengLei CHEN LinGen XIA ShaoJun KONG Rui GE YanLin | 2022 | Science China(Technological Sciences)2022，65，3： | 2 |

| 16 | Effect of high pressure sintering and annealing on microstructure and thermoelectric properties of nanocrystalline Bi_2Te_(2.7)Se_(0.3) doped with Gd显示文摘Bi2Te2.7Se0.3of high performance doped with Gd bulk materials was prepared by a high pressure(6.0 GPa) sintering(HPS) method at 593 K,633 K, 673 K and 693 K. The sample was then annealed for 36 h in a vacuum at 633 K. The phase composition, crystal structure and morphology of the sample were analyzed by X-ray diffraction and scanning electron microscopy. The electric conductivity, Seebeck coefficient, and thermal conductivity aspects of the sample were measured from 298 K to 473 K. The results show that high pressure sintering and the doping with Gd has a great effect on the crystal structure and the thermoelectric properties of the samples. The samples are consisted of nanoparticles before and after annealing, and these nanostructures have good stability at high temperature. HPS together with annealing can improve the TE properties of the sample by decreasing the thermal conductivity of the sample with nanostructures. The maximum ZT value of 0.74 was obtained at 423 K for the sample, which was sintered at 673 K and then annealed at 633 K for 36 h. Compared with the zone melting sample, it was increased by 85% at423 K. Hence the temperature of the maximum of figure of merit was increased. The results can be applied to the field of thermoelectric power generation materials. | Ping Zou Guiying Xu Song Wang Penglei Chen Fengzhu Huang | 2014 | Progress in Natural Science:Materials International2014，24，3： | 1 |
| 17 | Popping of g-C_3N_4 mixed with cupric nitrate: Facile synthesis of Cu-based catalyst for construction of C-N bond显示文摘A novel strategy to synthesize copper-based nanoparticles supported on carbon nitride(C3 N4) was developed by popping of mixture containing C3 N4 and cupric nitrate. Characterizations such as X-ray photoelectron spectroscopy(XPS) and X-ray diffraction(XRD) indicate that the structure of g-C3 N4 maintained although a popping process occurred. High resolution transmission electronic microscopy(HRTEM) characterization illustrated that copper-based nanoparticles with diameter of < 1 nm were well distributed on g-C3 N4. This kind of copper catalyst exhibits high catalytic activity and selectivity in arylation of pyrazole, a simple and effect strategy to construct C-N bond in organic chemistry.According to the results of control experiments and characterizations, cuprous oxide should be the catalytic active phase in the supported coperbased catalyst. | Shaoyu Yuan Penglei Cui Yunrui Zhang Hong Zhang Li Huo Yongjun Gao | 2018 | Green Energy & Environment2018，3，4： | 1 |

| 19 | Surgery is the means of treatment,but high-quality survival is the ultimate goal显示文摘Liver resection is the most effective treatment for primary liver cancer or colorectal liver metastasis(CRLM).Systemic chemotherapy,targeted therapy,immunotherapy,and local treatments are selectively performed to improve long-term survival.However,most patients have irresectable tumors at the time of diagnosis.One of the main factors affecting resection is insufficient postoperative future liver remnant(FLR)(1).To address this issue,various methods have been proposed to promote the hyperplasia of FLRs.Portal vein embolization(PVE),proposed by Makuuchi et al.(2)in 1990,involves the embolization of the portal vein on the tumor side via interventional methods to increase blood inflow to the contralateral portal vein.A hepatectomy of the affected side can then be performed after the development of sufficient FLR hyperplasia. | Penglei Ge Yang Wu | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 1 |
