| 2 | Ultra-sensitive Nanoprobe Modified with Tumor Cell Membrane for UCL/MRI/PET Multimodality Precise Imaging of Triple-Negative Breast Cancer显示文摘Triple-negative breast cancer(TNBC)is a subtype of breast cancer in which the estrogen receptor and progesterone receptor are not expressed,and human epidermal growth factor receptor 2 is not amplified or overexpressed either,which make the clinical diagnosis and treatment very challenging.Molecular imaging can provide an effective way to diagnose TNBC.Upconversion nanoparticles(UCNPs),are a promising new generation of molecular imaging probes.However,UCNPs still need to be improved for tumor-targeting ability and biocompatibility.This study describes a novel probe based on cancer cell membrane-coated upconversion nanoparticles(CCm-UCNPs),owing to the low immunogenicity and homologous-targeting ability of cancer cell membranes,and modified multifunctional UCNPs.This probe exhibits excellent performance in breast cancer molecular classification and TNBC diagnosis through UCL/MRI/PET tri-modality imaging in vivo.By using this probe,MDA-MB-231 was successfully differentiated between MCF-7 tumor models in vivo.Based on the tumor imaging and molecular classification results,the probe is also expected to be modified for drug delivery in the future,contributing to the treatment of TNBC.The combination of nanoparticles with biomimetic cell membranes has the potential for multiple clinical applications. | Hanyi Fang Mengting Li Qingyao Liu Yongkang Gai Lujie Yuan Sheng Wang Xiao Zhang Min Ye Yongxue Zhang Mingyuan Gao Yi Hou Xiaoli Lan | 2020 | Nano-Micro Letters2020，12，5： | 5 |
| 3 | Preparation of pitch precursor with excellent spinnability for general-purpose carbon fibre using coal tar pitch as raw material显示文摘Tetrahydrofuran(THF) extract of coal tar pitch(CTP) was used instead of blending CTP with pretreated pyrolysis fuel oil to prepare an isotropic pitch precursor with excellent spinnability for general-purpose carbon fibre through bromination-dehydrobromination. The feasibility and effectiveness of synthesising an isotropic pitch precursor derived from THF-soluble(CTP-THFs) is demonstrated in this study.The results show that CTP-THFs contains more light components than CTP;CTP-THFs and CTP monomer proportions were 62.52% and 45.32%, respectively. However, based on comparisons of CTP-THFsBr0 and CTPBr0 characterisations, CTP-THFs exhibits better polycondensation than CTP. Bromination-dehydrobro mination promotes polycondensation of pitch precursors, leading to greater carbon aromaticity in CTP-THFsBr5, CTP-THFsBr10, and CTP-THFsBr15 than that in CTP-THFsBr0 and CTPBr0. CTP-THFsBr5 and CTP-THFsBr10 have excellent spinnability even with softening points as high as 230 ℃. The pericondensed carbon and carbon aromaticity of CTP-THFsBr5 and CTP-THFsBr10 are high owing to the higher degree of polycondensation;however, they still possess a more linear molecular structure. The as-prepared carbon fibre exhibits homogeneity and uniformity, and the mechanical performance is comparable with that of commercial general-purpose carbon fibre products. | Jinchang Liu Chenyang Shen Lujie Huang Tinghao Fang Yaping Li Dingcheng Liang Qiang Xie | 2023 | Chinese Journal of Chemical Engineering2023，54，2： | 3 |

| 6 | Drying curve simulation and LF-NMR online monitor of water state in ursolic acid loaded chitosan nanoparticles during microwave freeze drying显示文摘The changes in various states of water in ursolic acid(UA)loaded chitosan nanoparticles were assessed using lowfield nuclear magnetic resonance(LF-NMR)during microwave freeze drying(MFD)process,and six thin-layer models were applied to simulate the drying kinetics.UA nanoparticles were dried at different microwave power densities(1 W/g,2 W/g and 4 W/g).The results showed that three water fractions with different transverse relaxation times(T_(2))were detected in fresh UA nanoparticles.The T_(2)relaxation time of water decreased significantly with drying time at different microwave power densities.And the mutual migration and transformation of water in different states during the drying process of chitosan nanoparticles occurred.Furthermore,mathematical model analysis showed that the Page model provided the best description during the process of UA nanoparticle dried by MFD.The Page model can better simulate the drying kinetics of chitosan nanoparticles dried by MFD,and LF-NMR technology can monitor the changes in water status of UA nanoparticles.The results revealed that LF-NMR can monitor the changes of water in UA nanoparticles during the drying process. | Xing Ren Xu Duan Weiwei Cao Lujie Zhao Guangyue Ren Panpan Liu | 2023 | International Journal of Agricultural and Biological Engineering2023，16，4： | 0 |
| 7 | Physical regulation of copper catalyst with a hydrophobic promoter for enhancing CO_(2)hydrogenation to methanol显示文摘The hydrogenation of CO_(2)to methanol,which is restricted by water products,requires a selective removal of water from the reaction system.Here,we show that physically combining hydrophobic polydivinylbenzene with a copper catalyst supported by silica can increase methanol production and CO_(2)conversion.Mechanistic investigation reveals that the hydrophobic promoter could hinder the oxidation of copper surface by water,maintaining a small fraction of metallic copper species on the copper surface with abundant Cu^(δ+),resulting in high activity for the hydrogenation.Such a physically mixed catalyst survives the continuous test for 100 h owing to the thermal stability of the polydivinylbenzene promoter. | Hangjie Li Wei Fang Ling-Xiang Wang Yifeng Liu Lujie Liu Tulai Sun Ciqi Liao Yihan Zhu Liang Wang Feng-Shou Xiao | 2023 | The Innovation2023，4，4： | 0 |
| 8 | Strategies for Improving the Training Quality of International Students in China显示文摘In recent years,the new measures for opening up have transitioned from concept to action,and from vision to reality,with good outcomes.China is becoming the target country for students from countries around the world to further their studies,and important changes have taken place in the source structure and major selection of international students.Quality is the lifeline of education in China.The key to improving international competitiveness is to improve the training quality.In order to improve the training quality of international students,the principle of teaching students in accordance with their aptitude needs to be implemented,the teaching methods that meet the characteristics of international students should be used,modern information means based on“Internet+Teaching”should be used,and joint training between schools and enterprises should be carried out,so as to promote both,classroom teaching and practical teaching. | Luji Liu | 2022 | Journal of Contemporary Educational Research2022，6，6： | 0 |
| 9 | Manufacturing N,O-carboxymethyl chitosan-reduced graphene oxide under freeze-dying for performance improvement of Li-S battery显示文摘Lithium-sulfur(Li-S) batteries can provide far higher energy density than currently commercialized lithium ion batteries, but challenges remain before it they are used in practice.One of the challenges is the shuttle effect that originates from soluble intermediates, like lithium polysulfides. To address this issue, we report a novel laminar composite, N,O-carboxymethyl chitosan-reduced graphene oxide(CC-rGO), which is manufactured via the self-assembly of CC onto GO and subsequent reduction of GO under an extreme condition of 1 Pa and-50°C. The synthesized laminar CC-rGO composite is mixed with acetylene black(AB) and coated on a commercial polypropylene(PP) membrane, resulting in a separator(CC-rGO/AB/PP) that can not only completely suppress the polysulfides penetration, but also can accelerate the lithium ion transportation, providing a Li-S battery with excellent cyclic stability and rate capability. As confirmed by theoretic simulations, this unique feature of CC-rGO is attributed to its strong repulsive interaction to polysulfide anions and its benefit for fast lithium ion transportation through the paths paved by the heteroatoms in CC. | Zhibin Jiang Lujie Jin Xiying Jian Jinxia Huang Hongshuai Wang Binhong Wu Kang Wang Ling Chen Youyong Li Xiang Liu Weishan Li | 2023 | International Journal of Extreme Manufacturing2023，5，1： | 0 |
| 10 | A Research on the Path to Strengthen Legal Education for International Students in China显示文摘With the deepening of China’s new measures for opening-up,China has emerged as the“target country”for students from many countries around the world seeking to study abroad.In China,legal education for international students is closely linked to the overall improvement of international students’training quality,which is conducive to improving the international education supply level for international students in colleges and universities,as well as maintaining the order of education for these students in China.In order to strengthen legal education for international students in China,it is necessary to set up public compulsory courses for legal education,form full-time teaching faculties,and explore the new cooperative teaching mode between the first classroom and the second classroom. | Luji Liu | 2022 | Journal of Contemporary Educational Research2022，6，7： | 0 |
| 11 | Effect of Heat Treatment on Gradient Microstructure and Tensile Property of Laser Powder Bed Fusion Fabricated 15-5 Precipitation Hardening Stainless Steel显示文摘This work investigated the gradient microstructure evolution and tensile property of LPBF fabricated 15-5 precipitation hardening stainless steel in post-process direct ageing(DA)and solution treating&ageing(STA).The varied microstructures for austenite and small-sized oxide inclusions at different sample heights in the as-built(AB)condition was generally preserved after DA treatment.However,austenite was almost disappeared,and oxide particle grew significantly after the STA treatment.As a result,the tensile property differences in sample top and bottom for AB and DA conditions did not occur in the STA samples.For the influence of post-process heat treatment,the STA condition had the highest yield strength due to the highest volume fraction of nano-sized Cu precipitates.However,the DA specimen had the highest ultimate tensile strength and elongation owing to the considerable amount of austenite phase and associated transformation induced plasticity effect. | Sheng Cao Hongyu Liu Jin Jiang Ke He Binghua Lv Hao Zhang Lujie Zhang Jingrong Meng Hao Deng Xiaodong Niu | 2024 | Acta Metallurgica Sinica(English Letters)2024，37，1： | 0 |
| 12 | Application of Big Data Technology in Evaluation of Operating Status of High-pressure Hydrogenation Heat Exchanger显示文摘The high-pressure hydrogenation heat exchanger is an important equipment of the refinery, but it is exposed to the problem of leakage caused by ammonium salt corrosion. Therefore, it is very important to evaluate the operating status of the hydrogenation heat exchanger. To improve the method for evaluating the operating status of hydrogenation heat exchangers by using the traditional method, this paper proposes a new method for evaluating the operation of hydrogenation heat exchangers based on big data. To address the noisy data common in the industry, this paper proposes an automated noisy interval detection algorithm. To deal with the problem that the sensor parameters have voluminous and unrelated dimensions, this paper proposes a key parameter detection algorithm based on the Pearson correlation coefficient. Finally, this paper presents a system-based health scoring algorithm based on PCA(Principal Component Analysis) to assist site operators in assessing the health of hydrogenation heat exchangers. The evaluation of the operating status of the hydrorefining heat exchange device based on big data technology will help the operators to more accurately grasp the status of the industrial system and have positive guiding significance for the early warning of the failure. | Li Lujie Liu Xu Du Rui Xu Peng | 2018 | China Petroleum Processing & Petrochemical Technology2018，20，3： | 0 |
