| 1 | Effect of thermomechanical treatment on microstructure and properties of Cu-Cr-Zr-Ag alloy显示文摘The effects of thermomechanical treatment on the properties and microstructure of Cu-Cr-Zr alloy and Cu-Cr-Zr-Ag alloy were investigated. Ag addition improves the mechanical properties of the alloy through solid solution strengthening and brings a little effect on the electrical conductivity of the alloy. A new Cu-Cr-Zr-Ag alloy was developed, which has an excellent combination of the tensile strength, elongation, and electrical conductivity reaching 476.09 MPa, 15.43% and 88.68% IACS respectively when subjected to the optimum thermomechanical treatment, i.e., solution-treating at 920°C for 1 h, cold drawing to 96% deformation, followed by aging at 400°C for 3 h. TEM analysis re-vealed two kinds of finely dispersed precipitates of Cr and Cu4Zr. It is very important to use the mechanisms of solid solution strengthening, work hardening effect as well as precipitate pinning effect of dislocations to improve tensile strength of the alloy without adversely affecting its electrical conductivity. | XIE Haofeng MI Xujun HUANG Guojie GAO Baodong YIN Xiangqian LI Yanfeng | 2011 | Rare Metals2011，30，6： | 17 |
| 2 | Reconfigurable directional coupler in lithium niobate crystal fabricated by three-dimensional femtosecond laser focal field engineering显示文摘For crystals, depressed cladding waveguides have advantages such as preservation of the spectroscopic as well as non-linear properties and the capability to guide both horizontal and vertical polarization modes, but fabrication is always quite time consuming. In addition, it is usually difficult to couple modes propagating in different depressed cladding waveguides through evanescent field overlap, so it is often required to dynamically reconfigure photonic waveguide devices using external fields for classical or quantum applications. Here, we experimentally demonstrate the single-scan femtosecond laser transverse writing of depressed cladding waveguides to form a 2 × 2 directional coupler inside lithium niobate crystal, which is integrated with two deeply embedded microelectrodes on both sides of the interaction region to reconfigure the coupling. By focal field engineering of the femtosecond laser, we specially generate a three-dimensional longitudinally oriented ring-shaped focal intensity profile composed of 16 discrete spots to simultaneously write the entire cladding region. The fabricated waveguides exhibit good single guided modes in two orthogonal polarizations at 1550 nm. By applying voltage to the deeply embedded microelectrodes fabricated with the femtosecond laser ablation followed by selective electroless plating, we successfully facilitate the light coupling from the input arm to the cross arm and thus actively tune the splitting ratio. These results open new important perspectives in the efficient fabrication of reconfigurable complex three-dimensional devices in crystals based on depressed cladding waveguides. | Qian Zhang Meng Li Jian Xu Zijie Lin Haofeng Yu Min Wang Zhiwei Fang Ya Cheng Qihuang Gong Yan Li | 2019 | Photonics Research2019，7，5： | 7 |
| 3 | The analysis of electrical performances of nanowires silicon solar cells显示文摘A theoretical model of silicon solar cells with ultra-small textured surface has been established based on depletion approximation and drift diffusion theory. The ultra-small textured surface achieves the low reflectance by multiple reflections among the silicon nanowires(NWs) . The electrical performances of the solar cells,including open circuit voltage(Voc),short circuit current(Isc) and conversion efficiency(η),are analyzed by the theoretical model. The results show that the low reflectance is not the only pursuit in manufacturing the Si NWs solar cells. Other factors including optimizing the surface passivation,improving the silicon wafers quality and designing the proper nanowire length should be considered together with NWs structure. | LI HaoFeng JIA Rui DING WuChang CHEN Chen MENG YanLong LIU XinYu | 2011 | Science China(Technological Sciences)2011，54，12： | 4 |
| 4 | Film Cooling Performance of a Row of Dual-fanned Holes at Various Injection Angles显示文摘Film cooling performance about a row of dual-fanned holes with injection angles of 30°, 60 ° and 90° were experimentally investigated at blowing ratios of 1.0 and 2.0. Dual-fanned hole is a novel shaped hole which has both inlet expansion and outlet expansion. A transient thermochromic liquid crystal technique was used to reveal the local values of film cooling effectiveness and heat transfer coefficient. The results show that injection angles have strong influence on the two dimensional distributions of film cooling effectiveness and heat transfer coefficient. For the small injection angle of 30 degree and small blowing ratio of 1.0, there is only a narrow spanwise region covered with film. The increase of injection angle and blowing ratio both leads to the enhanced spanwise film diffusion, but reduced local cooling ability far away from the hole. Injection angles have comprehensive influence on the averaged film cooling effectiveness for various x/d locations. As injection angles are 30 and 60 degree, two bands of high heat transfer coefficients are found in mixing region of the gas and coolant. As injection angle increases to 90 degree, the mixing leads to the enhanced heat transfer region near the film hole. The averaged heat transfer coefficient increases with the increase of injection angle. | LI Guangchao WANG Haofeng ZHANG Wei KOU Zhihai XU Rangshu | 2017 | Journal of Thermal Science2017，26，5： | 4 |
| 5 | An accurate solution of point kinetics equations of one-group delayed neutrons and an extraneous neutron source for step reactivity insertion显示文摘The continuous indication of the neutron density and its rate of change are important for the safe startup and operation of reactors. The best way to achieve this is to obtain analytical solutions of the neutron kinetics equations because none of the developed numerical methods can well satisfy the need for real-time or even super-time computation for the safe startup and operation of reactors in practice. In this paper, an accurate analytical solution of point kinetics equations with one-group delayed neutrons and an extraneous neutron source is proposed to calculate the change in neutron density, where the whole process from the subcritical stage to critical and supercritical stages is considered for step reactivity insertions. The accurate analytical solution can also be used as a benchmark of all numerical methods employed to solve stiff neutron kinetics equations. | LI HaoFeng SHANG XueLi CHEN WenZhen | 2010 | Chinese Science Bulletin2010，55，36： | 3 |
| 6 | A triple-RBD-based mucosal vaccine provides broad protectionagainst SARS-CoV-2 variants of concern显示文摘The rapid mutation and spread of SARS-CoV-2 variants urge the development of effective mucosal vaccines to provide broadspectrum protection against the initial infection and thereby curb the transmission potential.Here,we designed a chimeric tripleRBD immunogen,3Ro-NC,harboring one Delta RBD and two Omicron RBDs within a novel protein scaffold.3Ro-NC elicits potent and broad RBD-specific neutralizing immunity against SARS-CoV-2 variants of concern.Notably,intranasal immunization with 3RoNC plus the mucosal adjuvant KFD(3Ro-NC+KFDi.n)elicits coordinated mucosal IgA and higher neutralizing antibody specificity(closer antigenic distance)against the Omicron variant.In Omicron-challenged human ACE2 transgenic mice,3Ro-NC+KFDi.n immunization significantly reduces the tissue pathology in the lung and lowers the viral RNA copy numbers in both the lung(85.7-fold)and the nasal turbinate(13.6-fold).Nasal virologic control is highly correlated with RBD-specific secretory IgA antibodies.Our data show that 3Ro-NC plus KFD is a promising mucosal vaccine candidate for protection against SARS-CoV-2 Omicron infection,pathology and transmission potential. | Jingyi Yang Mei-Qin Liu Lin Liu Xian Li Mengxin Xu Haofeng Lin Shuning Liu Yunqi Hu Bei Li Bowen Liu Min Li Ying Sun Yao-Qing Chen Zheng-Li Shi Huimin Yan | 2022 | Cellular & Molecular Immunology2022，19，11： | 3 |
| 7 | Improving photosynthesis of microalgae by changing the ratio of light-harvesting pigments显示文摘Changing the ratio of light-harvesting pigments was regarded as an efficient way to improve the photosyn-thesis rate in microalgae, but the underlying mechanism is still unclear. In the present study, a mutant of Anabeana simensis (called SP) was selected from retrieved satellite cul-tures. Several parameters related with photosynthesis, such as the growth, photosynthesis rate, the content of photosyn-thetic pigment, low temperature fluorescence spectrum (77K) and electron transport rate, were compared with those of the wild type. It was found that the change in the ratio of light-harvesting pigments in the mutant led to more efficient light energy transfer and usage in mutant than in the wild type. This may be the reason why the mutant had higher photosynthesis and growth rates. | WANG Gaohong CHEN Lanzhou LI Genbao LI Dunhai HU Chunxiang CHEN Haofeng LIU Yongding SONG Lirong | 2005 | Chinese Science Bulletin2005，50，15： | 3 |

| 10 | ABNORMAL SHOOT 6 interacts with KATANIN 1 and SHADE AVOIDANCE 4 to promote cortical microtubule severing and ordering in Arabidopsis显示文摘Plant interphase cortical microtubules(cMTs)mediate anisotropic cell expansion in response to environmental and developmental cues.In Arabidopsis thaliana,KATANIN 1(KTN1),the p60 catalytic subunit of the conserved MT-severing enzyme katanin,is essential for cMT ordering and anisotropic cell expansion.However,the regulation of KTN1-mediated cMT severing and ordering remains unclear.In this work,we report that the Arabidopsis IQ67 DOMAIN(IQD)family gene ABNORMAL SHOOT 6(ABS6)encodes a MT-associated protein.Overexpression of ABS6 leads to elongated cotyledons,directional pavement cell expansion,and highly ordered transverse cMT arrays.Genetic suppressor analysis revealed that ABS6-mediated cMT ordering is dependent on KTN1 and SHADE AVOIDANCE 4(SAV4).Live imaging of cMT dynamics showed that both ABS6 and SAV4 function as positive regulators of cMT severing.Furthermore,ABS6 directly interacts with KTN1 and SAV4 and promotes their recruitment to the cMTs.Finally,analysis of loss-of-function mutant combinations showed that ABS6,SAV4,and KTN1 work together to ensure the robust ethylene response in the apical hook of dark-grown seedlings.Together,our findings establish ABS6 and SAV4 as positive regulators of cMT severing and ordering,and highlight the role of cMT dynamics in fine-tuning differential growth in plants. | Yuanfeng Li Meng Deng Haofeng Liu Yan Li Yu Chen Min Jia Hui Xue Jingxia Shao Jun Zhao Yafei Qi Lijun An Fei Yu Xiayan Liu | 2021 | Journal of Integrative Plant Biology2021，63，4： | 2 |

| 17 | Sustainable preparation of graphene-analogue boron nitride by ball-milling for adsorption of organic pollutants显示文摘The method of fabricating low-cost adsorbents with high activity and durability via a convenient and ecofriendly procedure is of great importance to wastewater treatment. Herein, a high-efficient mechanical exfoliation strategy was proposed to facilely prepare few-layered graphene-analogue boron nitride(BN) via a one-step non-organic solvent assisted wet ball mill procedure. Ball-milling treatment increased the specific surface area of BN 3.5-fold by reducing the thickness to ~3 layers with 45 min. The exfoliated BN exhibited strikingly improved sorption performance to organic contaminants with around 124% and 116% increased removal efficiency respectively for oxytetracycline(OTC) and Rhodamine B(RhB) as compared to the bulk BN. Batches sorption experiments showed that the sorption processes were thermodynamic endothermic, and well fitted to pseudo-second-order kinetic model and Freundlich isotherm equation. The π-π stacking interaction, hydrophobic effect and electrostatic interaction were proposed as the dominated sorption mechanism. In addition, no significant decline in adsorptive removal ability for the sorbent after 5 times recycling. The results indicate that the ball-milling exfoliation is a fast, green,sustainable and promising strategy for synthesis of highly potent BN based two-dimensional layered adsorbents. | Haofeng Wu Yanhong Chao Yan Jin Duanjian Tao Xiaowei Li Jing Luo Guohua Xia Linhua Zhu Wenshuai Zhu | 2022 | Chinese Journal of Chemical Engineering2022，35，2： | 1 |
