| 1 | Shoshonitic intrusive suite in SE Guangxi: Petrology and geochemistry显示文摘A NE-direction Mesozoic shoshonitic intrusive s黫te in SE Guangxi has been identified in terms of geological, petrological and geochemical investigations. The shoshonitic intrusives are characterized by enrichment of LILE, HFSE and LREE and no obvious Nb-Ta depletion, similar to those potassic rocks formed in within-plate and rifting environments. Unlike most shoshonitic rocks forming in arc settings, the SE Guangxi shoshonitic intrusives were likely generated during regional lithosphere extension induced by upwelling of asthenosphere mantle. | LI Xianhua ZHOU Hanwen LIU Ying LEE Chi-yu SUN Min CHEN Chenhong | 2000 | Chinese Science Bulletin2000，45，7： | 32 |
| 2 | Room temperature ferromagnetism in ultra-thin van der Waals crystals of 1T-CrTe2显示文摘Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications. | Xingdan Sun Wanying Li Xiao Wang Qi Sui Tongyao Zhang Zhi Wang Long Liu Da Li Shun Feng Siyu Zhong Hanwen Wang Vincent Bouchiat Manuel Nunez Regueiro Nicolas Rougemaille Johann Coraux Anike Purbawati Abdellali Hadj-Azzem Zhenhua Wang Baojuan Dong Xing Wu Teng Yang Guoqiang Yu Bingwu Wang Zheng Han Xiufeng Han Zhidong Zhang | 2020 | Nano Research2020，13，12： | 6 |
| 3 | In-situ synthesis of PHEMA magnetic nanogels via photochemical method显示文摘One-pot synthesis of magnetic nanogels via photochemical method is reported in this paper. Poly(2-hydroxyethyl methacrylate)(PHEMA) magnetic nanogels are synthesized by in-situ polymeriza-tion of 2-hydroxyethyl methacrylate(HEMA) and N,N'-methylene-bis-(acrylamide)(MBA) in Fe3O4 aqueous suspension under UV irradiation. The structure and compositions of magnetic nanogels are characterized by FTIR,TGA,SEM,TEM and PCS. TGA measurement indicates that magnetic nanogels contain 90% magnetite. Both naked Fe3O4 and magnetic nanogels are superparamagnatic at room temperature according to magnetization curves. The swollen capability of the hydrogel shell is proved by contrasting the particles sizes obtained by SEM,TEM and PCS. Particle diameters can be manipu-lated by changing monomer concentration and irradiation time. A mechanism of the coating process is proposed. | GONG PeiJun SUN HanWen HONG Jun XU DongMei YAO SiDe | 2007 | Science China Chemistry2007，50，2： | 4 |
| 4 | Poly(PEGMA) magnetic nanogels:Preparation via photochemical method,characterization and application as drug carrier显示文摘One-pot synthesis of magnetic nanogels with excellent biocompatibility via the photochemical method is reported in this paper.Poly(PEGMA) modified superparamagnetic nanogels(poly(PEGMA) magnetic nanogels) were synthesized by in-situ polymerization using poly(ethylene glycol) methacrylate(PEGMA) as the monomer and N,N'-methylene-bis-(acrylamide)(MBA) as the cross-linking agent in magnetite aqueous suspension under UV irradiation.The surface functional groups and components of magnetic nanogels were analyzed by Fourier transform infrared spectroscopy(FTIR) and a thermogra-vimetric analyzer(TGA).The results indicated that the poly(PEGMA) magnetic nanogels were synthe-sized successfully by coating poly(PEGMA) on the Fe3O4 nanoparticles under UV irradiation,and the Fe3O4 nanoparticles content in this nanogels was above 50 wt%.The morphology,size,zeta-potential and magnetic property were also characterized.The magnetic nanogels had a nearly spherical shape and core-shell structure,the average size in aqueous system measured by photon correlation spec-troscopy(PCS) was 68.4 nm,which was much bigger than that in the dry state,the nanogels behaved superparamagnetically with saturated magnetization of 58.6 emu/g,and the zeta-potential was-16.3-_17.3 mV at physiological pH(6.8-7.4) which could help to maintain stability in blood.The preliminary application as drug carrier was made and the doxorubicin-loaded magnetic nanogels had an excellent property in slow-release.The experiment indicated that the magnetic nanogel was an ideal candidate carrier in target drug delivery systems and other biomedical application. | SUN HanWen ZHANG LianYing ZHU XinJun KONG ChunYan ZHANG CunLan YAO SiDe | 2009 | Science China Chemistry2009，52，1： | 2 |

| 7 | Dimensional Gradient Structure of CoSe2@CNTs-MXene Anode Assisted by Ether for High-Capacity,Stable Sodium Storage显示文摘Recently,abundant resources,low-cost sodium-ion batteries are deemed to the new-generation battery in the field of largescale energy storage.Nevertheless,poor active reaction dynamics,dissolution of intermediates and electrolyte matching problems are significant challenges that need to be solved.Herein,dimensional gradient structure of sheet-tube-dots is constructed with CoSe2@CNTs-MXene.Gradient structure is conducive to fast migration of electrons and ions with the association of ether electrolyte.For half-cell,CoSe2@CNTs-MXene exhibits high initial coulomb efficiency(81.7%)and excellent cycling performance(400 mAh g^-1 cycling for 200 times in 2 Ag^−1).Phase transformation pathway from crystalline CoSe2-Na2Se with Co and then amorphous CoSe2 in the discharge/charge process is also explored by in situ X-ray diffraction.Density functional theory study discloses the CoSe2@CNTs-MXene in ether electrolyte system which contributes to stable sodium storage performance owing to the strong adsorption force from hierarchical structure and weak interaction between electrolyte and electrode interface.For full cell,CoSe2@CNTs-MXene//Na3V2(PO4)3/C full battery can also afford a competitively reversible capacity of 280 mAh g^−1 over 50 cycles.Concisely,profiting from dimensional gradient structure and matched electrolyte of CoSe2@CNTs-MXene hold great application potential for stable sodium storage. | Enze Xu Pengcheng Li Junjie Quan Hanwen Zhu Li Wang Yajing Chang Zhenjie Sun Lei Chen Dabin Yu Yang Jiang | 2021 | Nano-Micro Letters2021，13，2： | 1 |

| 15 | A monolithically sculpted van der Waals nano-opto-electro-mechanical coupler显示文摘The nano-opto-electro-mechanical systems(NOEMS)are a class of hybrid solid devices that hold promises in both classical and quantum manipulations of the interplay between one or more degrees of freedom in optical,electrical and mechanical modes.To date,studies of NOEMS using van der Waals(vdW)heterostructures are very limited,although vdW materials are known for emerging phenomena such as spin,valley,and topological physics.Here,we devise a universal method to easily and robustly fabricate vdW heterostructures into an architecture that hosts opto-electro-mechanical couplings in one single device.We demonstrated several functionalities,including nano-mechanical resonator,vacuum channel diodes,and ultrafast thermo-radiator,using monolithically sculpted graphene NOEMS as a platform.Optical readout of electric and magnetic field tuning of mechanical resonance in a CrOCl/graphene vdW NOEMS is further demonstrated.Our results suggest that the introduction of the vdW heterostructure into the NOEMS family will be of particular potential for the development of novel lab-on-a-chip systems. | Tongyao Zhang Hanwen Wang Xiuxin Xia Ning Yan Xuanzhe Sha Jinqiang Huang Kenji Watanabe Takashi Taniguchi Mengjian Zhu Lei Wang Jiantou Gao Xilong Liang Chengbing Qin Liantuan Xiao Dongming Sun Jing Zhang Zheng Han Xiaoxi Li | 2022 | Light(Science & Applications)2022，11，3： | 1 |
