| 1 | Switchable dual-wavelength Q-switched fiber laser using multilayer black phosphorus as a saturable absorber显示文摘Black phosphorus(BP), with thickness-dependent direct energy bandgaps(0.3–2 eV), shows an enhanced nonlinear optical response at near-and mid-infrared wavelengths. In this paper, we present experimentally multilayer BP flakes coated on microfiber(BCM) as a saturable absorber with a modulation depth of 16% and a saturable intensity of 6.8 MW∕cm^2. After inserting BCM into an Er-doped fiber ring laser, a stable dual-wavelength Q-switched state with central wavelengths of 1542.4 nm and 1543.2 nm(with wavelength spacing as small as 0.8 nm) is obtained with the aid of two cascaded fiber Bragg gratings as a coarse wavelength selector.Moreover, single-wavelength Q-switched operation at 1542.4 nm or 1543.2 nm is also realized, which can be switched between the two wavelengths flexibly just by adjusting the intracavity birefringence. These results suggest that BP combined with the cascaded fiber gratings can provide a simple and feasible candidate for a multiwavelength fiber laser. Our fiber laser may have potential applications in terahertz generation, laser radar,and so on. | JUNMIN LIU Yu CHEN YING LI HAN ZHANG SHUIQIN ZHENG SHIXIANG Xu | 2018 | Photonics Research2018，6，3： | 8 |

| 7 | Antagonistic MADS-box transcription factors SEEDSTICK and SEPALLATA3 form a transcriptional regulatory network that regulates seed oil accumulation显示文摘Transcriptional regulation is essential for balancing multiple metabolic pathways that influence oil accumulation in seeds.Thus far,the transcriptional regulatory mechanisms that govern seed oil accumulation remain largely unknown.Here,we identified the transcriptional regulatory network composed of MADS-box transcription factors SEEDSTICK(STK)and SEPALLATA3(SEP3),which bridges several key genes to regulate oil accumulation in seeds.We found that STK,highly expressed in the developing embryo,positively regulates seed oil accumulation in Arabidopsis(Arabidopsis thaliana).Furthermore,we discovered that SEP3 physically interacts with STK in vivo and in vitro.Seed oil content is increased by the SEP3 mutation,while it is decreased by SEP3 overexpression.The chromatin immunoprecipitation,electrophoretic mobility shift assay,and transient dual-luciferase reporter assays showed that STK positively regulates seed oil accumulation by directly repressing the expression of MYB5,SEP3,and SEED FATTY ACID REDUCER 4(SFAR4).Moreover,genetic and molecular analyses demonstrated that STK and SEP3 antagonistically regulate seed oil production and that SEP3 weakens the binding ability of STK to MYB5,SEP3,and SFAR4.Additionally,we demonstrated that TRANSPARENT TESTA 8(TT8)and ACYL-ACYL CARRIER PROTEIN DESATURASE 3(AAD3)are direct targets of MYB5 during seed oil accumulation in Arabidopsis.Together,our findings provide the transcriptional regulatory network antagonistically orchestrated by STK and SEP3,which fine tunes oil accumulation in seeds. | Shuangcheng He Yuanchang Min Zijin Liu Fang Zhi Rong Ma Ankang Ge Shixiang Wang Yu Zhao Danshuai Peng Da Zhang Minshan Jin Bo Song Jianjun Wang Yuan Guo Mingxun Chen | 2024 | Journal of Integrative Plant Biology2024，66，1： | 0 |
| 8 | Selective Hydrogenation of Phenylacetylene by Carbon Monoxide and Water显示文摘Catalytic selective hydrogenation of alkynes to the corresponding alkenes is an important process in industrial production.Modulating the selective hydrogenation of alkynes to the alkenes requires ingenuity since alkenes can easily be converted into the corresponding alkanes under reductive conditions.Applying different reductive reagents to prevent the direct usage of H_(2)can avoid difficulties in hydrogen storage and transportation.Herein,we demonstrate a tandem process to hydrogenate phenylacetylene by CO and H_(2)Oviathecouplingof thelow-temperaturewater-gas shift reaction and selective hydrogenation of phenylacetylene utilizing theα-MoC catalyst.The reductive reagent,CO,not only produces H_(2)from H_(2)O to drive the reaction forward,but it also regulates the selectivity of styrene by preventing further hydrogenation. | Xuetao Qin Ruiqi Zhang Ming Xu Yao Xu Lirong Zheng Chengyu Li Shixiang Yu Jie Yan Jinglin Xie Genghuang Wu Junfeng Rong Meng Wang Ding Ma | 2023 | CCS Chemistry2023，5，10： | 0 |

| 10 | Highly Efficient Aligned Ion‑Conducting Network and Interface Chemistries for Depolarized All‑Solid‑State Lithium Metal Batteries显示文摘Improving the long-term cycling stability and energy density of all-solid-state lithium(Li)-metal batteries(ASSLMBs)at room temperature is a severe challenge because of the notorious solid–solid interfacial contact loss and sluggish ion transport.Solid electrolytes are generally studied as two-dimensional(2D)structures with planar interfaces,showing limited interfacial contact and further resulting in unstable Li/electrolyte and cathode/electrolyte interfaces.Herein,three-dimensional(3D)architecturally designed composite solid electrolytes are developed with independently controlled structural factors using 3D printing processing and post-curing treatment.Multiple-type electrolyte films with vertical-aligned micro-pillar(p-3DSE)and spiral(s-3DSE)structures are rationally designed and developed,which can be employed for both Li metal anode and cathode in terms of accelerating the Li+transport within electrodes and reinforcing the interfacial adhesion.The printed p-3DSE delivers robust long-term cycle life of up to 2600 cycles and a high critical current density of 1.92 mA cm^(−2).The optimized electrolyte structure could lead to ASSLMBs with a superior full-cell areal capacity of 2.75 mAh cm^(−2)(LFP)and 3.92 mAh cm^(−2)(NCM811).This unique design provides enhancements for both anode and cathode electrodes,thereby alleviating interfacial degradation induced by dendrite growth and contact loss.The approach in this study opens a new design strategy for advanced composite solid polymer electrolytes in ASSLMBs operating under high rates/capacities and room temperature. | Yongbiao Mu Shixiang Yu Yuzhu Chen Youqi Chu Buke Wu Qing Zhang Binbin Guo Lingfeng Zou Ruijie Zhang Fenghua Yu Meisheng Han Meng Lin Jinglei Yang Jiaming Bai Lin Zeng | 2024 | Nano-Micro Letters2024，16，5： | 0 |
