| 1 | Reaction thermodynamics and kinetics on in situ Al_2O_3/Cu composites显示文摘The preferred internal oxidation of aluminum in Cu Al alloy was used to obtain in situ Al 2O 3/Cu composites. The reinforcement particles were mainly γ Al 2O 3, some θ Al 2O 3 and a little α Al 2O 3. Thermodynamics analyses show that the chemical reactions are 3Cu 2O+2Al=6Cu+Al 2O 3 or 3CuO+2Al=3Cu+Al 2O 3. A related equilibrium diagram was drawn. The experiments and investigation show that the formation rate of Al 2O 3 was controlled by the diffusion of oxygen in matrix. | Li Guobin(李国彬) 1, Wu Jianjun(武建军) 1, Guo Quanmei(郭全梅) 2, Jiang Yanfei(姜延飞) 1, Shen Yutian(申玉田) 1, Lei Tingquan(雷廷权) 2 1.

| 2 | Numerical experiment rock fragmentation by combined dynamic and static loads under dual-cutter head显示文摘This paper puts forward a new rock fragmentation loading method of dual-cutter head combined dynamic and static loads.By applying the numerical simulation software-RFPA2D,we have done numerical experiment about the siltstone's crushing effect by dynamic load on single cutter head without confining pressure,dynamic load on single cutter head with confining pressure 10MPa and different dual-cutter heads spacing by combined dynamic and static loads with confining pressure 10MPa.Experimental results show that the confining pressure can obviously affect the rock fragmentation effect.Combined dynamic and static loads can greatly improve the rock fragmentation effect.There exists an optimal spacing of dual-cutter head that can make the rock fragmentation achieve the desired effect.Through analyzing the acoustic emission accumulative energy and quantity,the authors make a conclusion that the optimum spacing is 30 mm. | Zhao Fujun Wang Hongyu Shen Peiwen Chen Caixian Xu Yanfei | 2012 | Engineering Sciences2012，10，2： | 3 |
| 3 | Tunable Dynamic Black Phosphorus/Insulator/Si Heterojunction Direct-Current Generator Based on the Hot Electron Transport显示文摘Static heterojunction-based electronic devices have been widely applied because carrier dynamic processes between semiconductors can be designed through band gap engineering.Herein,we demonstrate a tunable direct-current generator based on the dynamic heterojunction,whose mechanism is based on breaking the symmetry of drift and diffusion currents and rebounding hot carrier transport in dynamic heterojunctions.Furthermore,the output voltage can be delicately adjusted and enhanced with the interface energy level engineering of inserting dielectric layers.Under the ultrahigh interface electric field,hot electrons will still transfer across the interface through the tunneling and hopping effect.In particular,the intrinsic anisotropy of black phosphorus arising from the lattice structure produces extraordinary electronic,transport,and mechanical properties exploited in our dynamic heterojunction generator.Herein,the voltage of 6.1 V,current density of 124.0 A/m^(2),power density of 201.0 W/m^(2),and energy-conversion efficiency of 31.4%have been achieved based on the dynamic black phosphorus/AlN/Si heterojunction,which can be used to directly and synchronously light up light-emitting diodes.This direct-current generator has the potential to convert ubiquitous mechanical energy into electric energy and is a promising candidate for novel portable and miniaturized power sources in the in situ energy acquisition field. | Yanghua Lu Sirui Feng Runjiang Shen Yujun Xu Zhenzhen Hao Yanfei Yan Haonan Zheng Xutao Yu Qiuyue Gao Panpan Zhang Shisheng Lin | 2019 | Research2019，，1： | 2 |
| 4 | Abemaciclib induces apoptosis in cardiomyocytes by activating the Hippo signaling pathway显示文摘Abemaciclib is the newest cyclin-dependent kinase 4/6 inhibitor that has received approval from the US Food and Drug Administration for using in patients with advanced breast cancer. However, its potential adverse effects on cardiomyocytes remain unknown. In this study, we used the cell counting kit-8 assay, western blot analysis, flow cytometry, immunostaining, and quantitative polymerase chain reaction to investigate the role of abemaciclib in inducing apoptosis and in inhibiting the viability and proliferation of AC16 human cardiomyocyte cells. The results revealed that abemaciclib induced apoptosis and inhibited cell proliferation by activating the Hippo signaling pathway. This work demonstrates the molecular basis by which abemaciclib induces cardiac side effects, providing a theoretical basis and effective targets for the treatment of cardiac diseases. | Yajie Zhou Yanfei Li Junwei Shen Jue Li Xinming Li | 2020 | Acta Biochimica et Biophysica Sinica2020，52，8： | 2 |
| 5 | Recent progress in small molecule fluorescent probes for nitroreductase显示文摘Nitroreductase(NTR) is a member of flavin-containing enzymes that exists widely in bacteria. Hypoxia,which is a characteristic of locally advanced solid tumors, resulting from an imbalance between oxygen consumption and supply, can result in NTR overexpression. Using either nicotinamide adenine dinucleotide(NADH) or nicotinamide adenine dinucleotide phosphate(NADPH) as a source of reducing equivalents, NTR can catalyze the reduction of nitroaromatic compounds to the corresponding amines.Based on this reduction mechanism, NTR can be applied not only in the bioremediation and degradation of organic nitrogen compounds, but also in the development of NTR-targeted fluorescent probes to detect the hypoxic status of cancer cells. This review aims to provide a summary of the progress in fluorescent probes for NTR in recent years and elucidate the main fluorescent mechanisms that have been applied to design probes. | Wenjing Qin Chenchen Xu Yanfei Zhao Changmin Yu Sheng Shen Lin Li Wei Huang | 2018 | Chinese Chemical Letters2018，29，10： | 2 |
| 6 | Interfacial Built-In Electric Field-Driven Direct Current Generator Based on Dynamic Silicon Homojunction显示文摘Searching for light and miniaturized functional device structures for sustainable energy gathering from the environment is the focus of energy society with the development of the internet of things.The proposal of a dynamic heterojunction-based direct current generator builds up new platforms for developing in situ energy.However,the requirement of different semiconductors in dynamic heterojunction is too complex to wide applications,generating energy loss for crystal structure mismatch.Herein,dynamic homojunction generators are explored,with the same semiconductor and majority carrier type.Systematic experiments reveal that the majority of carrier directional separation originates from the breaking symmetry between carrier distribution,leading to the rebounding effect of carriers by the interfacial electric field.Strikingly,NN Si homojunction with different Fermi levels can also output the electricity with higher current density than PP/PN homojunction,attributing to higher carrier mobility.The current density is as high as 214.0 A/m^(2),and internal impedance is as low as 3.6 kΩ,matching well with the impedance of electron components.Furthermore,the N-i-N structure is explored,whose output voltage can be further improved to 1.3V in the case of the N-Si/Al2O3/N-Si structure,attributing to the enhanced interfacial barrier.This approach provides a simple and feasible way of converting low-frequency disordered mechanical motion into electricity. | Yanghua Lu Qiuyue Gao Xutao Yu Haonan Zheng Runjiang Shen Zhenzhen Hao Yanfei Yan Panpan Zhang Yu Wen Guiting Yang Shisheng Lin | 2020 | Research2020，，1： | 2 |
| 7 | Optimal power allocation for downlink two-user non-orthogonal multiple access in visible light communication显示文摘In this work,we consider employing the NOMA(Non-Orthogonal Multiple Access)technique in downlink VLC(Visible Light Communication)for performance enhancement.In particular,focusing on a typical NOMA scenario with two users,we optimize the power allocation strategies under both sum-rate maximization and max-min fairness criteria,where practical optical power and QoS(Quality of Service)constraints are included.As our main contribution,we achieve optimal power allocation solutions in semi-closed forms via mathematical analysis,which,to the best of our knowledge,have not been reported in literature.Simulation results demonstrate that NOMA can provide remarkable performance gains over OMA(Orthogonal Multiple Access)in the context of VLC downlinks. | Hong Shen Yanfei Wu Wei Xu Chunming Zhao | 2017 | Journal of Communications and Information Networks2017，2，4： | 2 |
| 8 | Experimental Investigation for Co-Combustion Characteristics of Semi-Coke and Bituminous Coal in a 3 MWth Tangential Combustion Facility显示文摘An experimental investigation was conducted in a 3 MW pilot-scale tangential combustion facility to explore the co-combustion characteristics of bituminous coal mixed with semi-coke.The thermal gravimetric analyzer(TGA)was used to obtained fuel thermal analysis.The results presented effects of semi-coke blending ratio(BR)on average furnace temperature,ignition temperature,NO emission and combustion efficiency.The excess air coefficient in main combustion sections and outlet were fixed at 0.85 and 1.2 while BR increased from 0%to 50 wt.%.The temperature profiles of combustion decreases along the height of furnace while average furnace temperature fluctuates slightly with an increasing BR.The concentration of NO has an increasing tendency with the increasing of BR.The ignition temperature obtained from TGA measurement agreed well with experiment result.In addition,combustion efficiency was not sensitive to BR and decreased slightly with the increasing BR. | GUAN Jingyu YU Qiang SUN Rui SHEN Tao WANG Minghao YAN Yanfei SONG Xin | 2020 | Journal of Thermal Science2020，29，6： | 2 |
| 9 | Highly stable lithium anode enabled by self-assembled monolayer of dihexadecanoalkyl phosphate显示文摘Li has been considered as the ultimate anode material for high energy density secondary Li batteries.However,its practical application has been limited due to its low Coulombic efficiency(CE)and the formation of lithium dendrites.Recently,we have developed a microspherical Li-carbon nanotube(Li-CNT)composite material passivated with octadecylphosphonic acid(OPA)self-assembled monolayer(SAM)exhibiting suppressed lithium dendrite formation and improved environmental/electrochemical stability.In this work,we demonstrated the significantly enhanced passivation effects of a SAM using dihexadecanoalkyl phosphate(DHP),a molecule that is comprised of double hydrophobic alkyl chains and forms a denser SAM on surfaces with large curvature.As a result,the DHP SAM delivers superior environmental and electrochemical stability to the OPA passivated Li-CNT material.In specific,the DHP passivated Li-CNT composite(DHP-Li-CNT)delivers a high CE of 99.25%under a 33.3%depth of discharge(DOD)at 1 C,when it is paired with a LiFePO4 cathode.The evolution of the SAM during cycling and the effects of DOD and current density on the CE of the DHP-Li-CNT anode have also been investigated.The improved SAM passivation constitutes an important step in achieving the goal of practically applicable Li anodes. | Lei Zheng Feng Guo Tuo Kang Jin Yang Ya Liu Wei Gu Yanfei Zhao Hongzhen Lin Yanbin Shen Wei Lu Liwei Chen | 2020 | Nano Research2020，13，5： | 1 |

| 11 | Remote plasma-enhanced atomic layer deposition of gallium oxide thin films with NH_3 plasma pretreatment显示文摘High quality gallium oxide(Ga_2O_3) thin films are deposited by remote plasma-enhanced atomic layer deposition(RPEALD) with trimethylgallium(TMG) and oxygen plasma as precursors. By introducing in-situ NH3 plasma pretreatment on the substrates, the deposition rate of Ga_2O_3 films on Si and GaN are remarkably enhanced, reached to 0.53 and 0.46 ?/cycle at 250 °C,respectively. The increasing of deposition rate is attributed to more hydroxyls(–OH) generated on the substrate surfaces after NH3 pretreatment, which has no effect on the stoichiometry and surface morphology of the oxide films, but only modifies the surface states of substrates by enhancing reactive site density. Ga_2O_3 film deposited on GaN wafer is crystallized at 250 °C, with an epitaxial interface between Ga_2O_3 and GaN clearly observed. This is potentially very important for reducing the interface state density through high quality passivation. | Hui Hao Xiao Chen Zhengcheng Li Yang Shen Hu Wang Yanfei Zhao Rong Huang Tong Liu Jian Liang Yuxin An Qing Peng Sunan Ding | 2019 | Journal of Semiconductors2019，40，1： | 1 |

| 14 | miR-3677-3p promotes hepatocellular carcinoma progression via inhibiting GSK3β显示文摘MicroRNAs play im portant roles in regulating hepatocellular carcinoma(HCC)form ation,progression and metastasis.However,their functions and the underlying m olecular mechanisms are still unclear.Here,we found that miR-3677-3p was highly expressed in prim ary tumor tissues of HCC patients.And its inhibition by using sponge in HCC cells could suppress cell proliferation sig nificantly,but it has no effect on cell apoptosis.Through directly targeting to the 37 untranslated region of glycogen synthase kinase 3-β(GSK3β),miR-3677-3p could inhibit GSK3β expression.Our study revealed that the miR-3677-3p/GSK3β axis may play a crucial role in HCC and miR-3677-3p may serve as a potential diagnostic biom arker or a therapeutic target for HCC. | Yanfei Li Yajie Zhou Linlin Ma Dingsheng Liu Zhensheng Dai Junwei Shen | 2020 | Acta Biochimica et Biophysica Sinica2020，52，12： | 1 |
