| 1 | Atomic-scaled surface engineering Ni-Pt nanoalloys towards enhanced catalytic efficiency for methanol oxidation reaction显示文摘Surface engineering is known as an effective strategy to enhance the catalytic properties of Pt-based nanomaterials.Herein,we report on surface engineering Ni-Pt nanoalloys with a facile method by varying the Ni doping concentration and oleylamine/oleicacid surfactant-mix.The alloy-composition,exposed facet condition,and surface lattice strain are,thereby manipulated to optimize the catalytic efficiency of such nanoalloys for methanol oxidation reaction(MOR).Exemplary nanoalloys including Ni_(0.69)Pt_(0.31)truncated octahedrons,Ni_(0.45)Pt_(0.55)nanomultipods and Ni_(0.20)Pt_(0.80)nanoflowers are thoroughly characterized,with a commercial Pt/C catalyst as a common benchmark.Their variations in MOR catalytic efficiency are significant:2.2 A/mgPt for Ni_(0.20)Pt_(0.80)nanoflowers,1.2 A/mgPt for Ni_(0.45)Pt_(0.55)nanomultipods,0.7 A/mgPt for Ni_(0.69)Pt_(0.31)truncated octahedrons,and 0.6 A/mgPt for the commercial Pt/C catalysts.Assisted by density functional theory calculations,we correlate these observed catalysis-variations particularly to the intriguing presence of surface interplanar-strains,such as{111}facets with an interplanar-tensile-strain of 2.6%and{200}facets with an interplanar-tensile-strain of 3.5%,on the Ni_(0.20)Pt_(0.80)nanoflowers. | Aixian Shan Shuoyuan Huang Haofei Zhao Wengui Jiang Xueai Teng Yingchun Huang Chinping Chen Rongming Wang Woon-Ming Lau | 2020 | Nano Research2020，13，11： | 6 |
| 2 | Direct observation of epitaxial alignment of Au on M0S2 at atomic resolution显示文摘The morphology and structural stability of metal/2D semic on ductor interfaces strongly affect the performa nee of 2D electronic devices and synergistic catalysis. However, the structural evolution at the interfaces has not been well explored particularly at atomic resolution. In this work, we study the structural evoluti on of Au nan oparticles (NPs) on few-layer MoS2 by high resol utio n transmissi on electro n microscopy (HRTEM) an d quan titative high-angle annular dark field seanning TEM. It is found that in the transition of Au from nan oparticles to den drites, a dynamically epitaxial align ment betwee n Au and MoS2 lattices is formed, and Moirc patter ns can be directly observed in HRTEM images due to the mismatch between Au and M0S2 lattices. This epitaxial alignment can occur in ambient conditions, and can also be accelerated by the irradiation of high-energy electron beam. In situ observation clearly reveals the rotation of Au NPs, the atom migration inside Au NPs, and the transfer of Au atoms between neighboring Au NPs, finally leading to the formation of epitaxially aligned Au dendrites on M0S2. The structural evoluti on of metal/2D semico nductor in terfaces at atomic scale can provide valuable information for the design and fabricatio n of the metal/2D semicon ductorn ano-devices with desired physical and chemical performa nces. | Yinghui Sun Haofei Zhao Dan Zhou Yuchen Zhu Huanyu Ye Yan Aung Moe | 2019 | Nano Research2019，12，4： | 4 |

| 4 | Non-symmetric hybrids of noble metal-semiconductor:Interplay of nanoparticles and nanostructures in formation dynamics and plasmonic applications显示文摘Noble metal-semiconductor hybrids have been employed as fundamental structures in modern technologies. In these hybrids, their cooperative multiple functions attract much attention in recent years because of the interplay of nanoparticles and nanostructures. In this review, we summarize the interplay of nanoparticles and nanostructures in specific kinds of noble metal-semiconductor hybrids, termed as non-symmetric hybrids of noble metal-semiconductor. It particularly refers to metal nanoparticles(or semiconducting quantum dots) at 1-dimensinal(1D) and 2-dimensional(2D) semiconductor(or metal) nanostructures, in contrast to the core/shell and heterodimer nanostructures. First, we discuss the formation dynamics, especially in chemical growth and assembly as well as physical coating and deposition, of non-symmetric noble metal-semiconductor hybrids with nanoparticles on nanostructures. Second, we introduce the plasmon-related applications of these hybrids in heterogeneous catalysis, optoelectronic or photovoltaic devices, all-optical devices, and surface detection or modulation. This review not only provides a comprehensive understanding of the formation mechanisms of the non-symmetric metal-semiconductor hybrid nanostructures, but also may inspire new ideas of novel functional devices and applications based on these systems. | Yinghui Sun Xianzhong Yang Haofei Zhao Rongming Wang | 2017 | Progress in Natural Science:Materials International2017，27，2： | 1 |
| 5 | Telomere-to-telomere genome of the allotetraploid legume Sesbania cannabina reveals transposon-driven subgenome divergence and mechanisms of alkaline stress tolerance显示文摘Alkaline soils pose an increasing problem for agriculture worldwide,but using stress-tolerant plants as green manure can improve marginal land.Here,we show that the legume Sesbania cannabina is very tolerant to alkaline conditions and,when used as a green manure,substantially improves alkaline soil.To understand genome evolution and the mechanisms of stress tolerance in this allotetraploid legume,we generated the first telomere-to-telomere genome assembly of S.cannabina spanning~2,087 Mb.The assembly included all centromeric regions,which contain centromeric satellite repeats,and complete chromosome ends with telomeric characteristics.Further genome analysis distinguished A and B subgenomes,which diverged approximately 7.9 million years ago.Comparative genomic analysis revealed that the chromosome homoeologs underwent large-scale inversion events(>10 Mb)and a significant,transposon-driven size expansion of the chromosome 5A homoeolog.We further identified four specific alkali-induced phosphate transporter genes in S.cannabina;these may function in alkali tolerance by relieving the deficiency in available phosphorus in alkaline soil.Our work highlights the significance of S.cannabina as a green tool to improve marginal lands and sheds light on subgenome evolution and adaptation to alkaline soils. | Haofei Luo Xiaofei Wang Changqing You Xuedan Wu Duofeng Pan Zhiyao Lv Tong Li Dongmei Zhang Zhongbao Shen Xiaodong Zhang Guodao Liu Kaixuan He Qingtong Ye Yajun Jia Qinghua Zhao Xian Deng Xiaofeng Cao Xianwei Song Gai Huang | 2024 | Science China(Life Sciences)2024，67，1： | 0 |
| 6 | Supramolecular complex glycoconjugate vaccine generates self-enhancement effects for carbohydrate antigen delivery显示文摘Targeting delivery of tumor-associated carbohydrate antigen(TACA)-based vaccine to antigen-presenting cells(APCs)mediated by endogenous antibodies can improve the immunogenicity of TACA.However,an essential requirement of this approach is to generate high titers of endogenous antibodies in vivo through pre-immunization,which complicates the immunization procedure and may cause side effects.Herein,we report a new generation of APC-targeting TACA-based supramolecular complex vaccine,assembled by sialyl Thomsen-nouveau-bovine serum albumin-adamantine(sTn-BSA-Ada)and heptavalent rhamnose(Rha)-modifiedβ-cyclodextrin(β-CD)via host-guest interaction.The complex vaccine retained anti-Rha antibodies recruiting capability and facilitated the APCs uptake of the vaccine via the interaction of the Fc-domain with the Fc receptors on APCs.We demonstrate that direct immunization of complex vaccine elicited anti-Rha and anti-sTn specific immune response synchronously,generating a novel self-enhancement effect that can improve the antigen delivery to APCs in high efficacy.The structure-activity relationship(SAR)study proved that complex vaccine 4 with polyethylene glycol 6(PEG 6)linker in host molecule provoked a robust and specific sTn immune response comparable to the pre-immunization approach.The antisera induced by complex vaccine,either through direct immunization or pre-immunization,exhibited equal potency of cytotoxicity against the sTn expression cancer cells.This study provides a general platform for TACA-based vaccines with self-enhancement effects without the need for pre-immunization. | Han Lin Yanchun Li Kun Zhou Dan Li Hangyan Yu Jie Zhao Haofei Hong Zhifang Zhou Zhimeng Wu | 2024 | Chinese Chemical Letters2024，35，2： | 0 |

| 8 | Interfacial space charge characteristic of PPLP insulation for HVDC cables显示文摘High-voltage DC(HVDC)cables show more efficiency than high-voltage AC cables over the long distance power transmission and have attracted significant attention recently due to rapid developments in off-shore wind farm.Polypropylene laminated paper(PPLP)insulation based HVDC cables have provided a reliable operation for many years and are the highest voltage level in operation at the moment.In this study,the authors intend to understand the electrical performance of PPLP insulation system by examining space charge in detail,especially at the interfaces.It has been found that the interface between polypropylene and Kraft paper acts as trap for charge carriers,resulting in an optimal electric field distribution in PPLP insulation system.The optimal electric field distribution enhances overall electrical performance of PPLP insulation,including higher dc breakdown strength and lower electrical conductivity. | Xuefeng Zhao Lu Pu Zhiqiang Xu George Chen Wei Duan Haofei Sun Zeli Ju | 2020 | High Voltage2020，5，5： | 0 |
| 9 | Carbon-Involved Near-Surface Evolution of Cobalt Nanocatalysts:An in Situ Study显示文摘When carbon-containing species are involved in reactions catalyzed by transition metals at high temperature,the diffusion of carbon on or in catalysts dramatically influences the catalytic performance.Acquiring information on the carbon-diffusioninvolved evolution of catalysts at the atomic level is crucial for understanding the reaction mechanism yet also challenging.For the chemical vapor deposition process of single-walled carbon nanotubes(SWCNTs),we recorded in situ the catalyst state(solid and molten)composition as well as near-surface structural and chemical evolution at the cobalt catalyst-tube interface with carbon permeation using aberration-corrected environmental transmission electron microscopy and synchrotron X-ray absorption spectroscopy.The nucleation of SWCNTs was linked with an alternating dissolving and precipitating cycle of carbon in catalysts close to the nucleation site.Understanding the dynamics of carbon atoms in catalysts brings deeper insight into the growth mechanism of SWCNTs and facilitates inferring mechanisms of other reactions.The methodologies developed here will find broad applications in studying catalytic and other processes. | Feng Yang Haofei Zhao Wu Wang Qidong Liu Xu Liu Yuecong Hu Xinrui Zhang Sheng Zhu Dongsheng He Yingying Xu Jiaqing He Rongming Wang Yan Li | 2021 | CCS Chemistry2021，3，11： | 0 |
| 10 | Hydrogen-bonded organic framework for red light-mediated photocatalysis显示文摘The development of heterogeneous molecule-based catalysts for red light-mediated photocatalysis is still challenging due to the improper light absorption for most materials and the photoactivity deactivation for solid assembly.Herein,red light photocatalysis with a hydrogen-bonded organic framework(HOF)is established.This HOF,named HOF-66,is formed from the self-assembly of guanine-decorated naphthalenediimide(NDI)molecule through hydrogen-bonded guanine-quadruplex nodes,showing square grid supramolecular layers confirmed by powder X-ray diffraction analysis.In contrast to unsubstituted NDI HOF,introduction of ethylamino groups to NDI core in HOF-66 tunes strong electronic maximum absorption peak to 619 nm,allowing red light photocatalysis of singlet oxygen evolution proved by 1,3-diphenylisobenzofuran degradation and electron spin resonance determination.Particularly,under the same conditions,the sulfide oxidation rate in the presence of HOF-66 was 28 times higher compared to its unsubstituted analogue.This work integrates the molecular design and aggregation effect towards the application of HOFs,opening a new gate for red light photocatalysts. | Haofei Zhao Ziwen Zhou Xuenan Feng Chao Liu Hui Wu Wei Zhou Hailong Wang | 2023 | Nano Research2023，16，7： | 0 |
