Pulse generation of erbium-doped fiber laser based on liquid-exfoliated FePS₃*

Chinese Physics B (2019)

Qing Rui Yin Jin Wang Xinyao Shi Tao Wang Jie Yang

As a preferable material in the field of photo-detection and catalysis, the characteristics of FePS 3 in broad wavelength range have been proven by many experimental studies. However, FePS 3 has not been used as a saturable absorber (SA) in fiber lasers yet. We propose and demonstrate the generation of a single wavelength and dual-wavelength based on an Er-doped fiber laser (EDFL) at 1.5 μ m by using an innovative FePS 3 saturable absorber for the first time. The result shows that a stable passively Q-switched pulse can be generated, which demonstrates that the new two-dimensional (2D) material FePS 3 served as SA provides a valid method to realize passively Q-switched laser. In addition, we achieve the output of the dual-wavelength pulse by properly rotating the polarization controller. To the best of our knowledge, the dual-wavelength pulse EDFL could be applied in biomedicine, spectroscopy, and sensing research.

CANTAC-seq analysis reveals E2f1 and Otx1 as a coupled repressor-activator pair co-modulating zygotic genome activation in Xenopus tropicalis

Research Square (Research Square) (2024)

Wei Chen Huanhuan Cui Weizheng Liang Zhaoying Shi Luming Zhang

Abstract Zygotic genome activation (ZGA) is tightly associated with the modulation of chromatin accessibility via maternal transcription factors. However, due to technical limitations, it remains elusive how the chromatin regulatory landscape is established during Xenopus tropicalis (X. tropicalis) ZGA and DNA binding transcription regulators involved in this process have therefore been underexplored. Here, by developing CANTAC-seq, we generated a first genome-wide map of accessible chromatin of early X. tropicalis embryos and found that the open chromatin landscape is progressively established at cis-regulatory elements during ZGA. Based on the motif analysis and perturbation experiments, we demonstrated E2f1, a well-known transcriptional activator, maintains a repressive chromatin environment independent of its negative effect on cell cycle progression before the MBT. Moreover, we identified another maternal factor Otx1 counteracts the inhibitory function of E2f1. The dynamic balance between the two factors determines the temporal regulation of a set of genes required for zygotic gene transcription and germ layer differentiation.

QTL detection for three tiller-related traits and their effects on yield in wheat (Triticum aestivum L.)

Research Square (Research Square) (2023)

Yibiao Cai Xiaohan Zhou Chenyang Wang Aifeng Liu Zhengcang Sun

Abstract Tiller related traits play important roles in determining yielding potential in wheat. It is of great value to elucidate the genetic basis of tiller number for the genetic improvement of wheat yield. In the present study, a recombinant inbred lines (RILs) mapping population derived from the cross between Kenong 9204 (KN9204) × Jing 411 (J411) (denoted by KJ-RILs) was used for quantitative trait locus (QTL) analysis of three tiller related traits. A total of 78 putative additive QTLs for spike number per plant (SNPP), the maximum tiller number (MTN) and ear-bearing tiller rate (EBTR) were detected in eight different environments. Among them, 12 repeatable QTL might be novel QTL that were firstly documented in the present study. The genetic effect analysis of two co-located major stable QTL, i.e., qSnpp-KJ-5D.1 and qMtn-KJ-5D.1 , on yield-related traits were characterized. Moreover, the favored alleles of qSnpp-KJ-5D.1 and qMtn-KJ-5D.1 have been undergone selection in wheat breeding programs; its future application potential in the genetic improvement of yield based on molecular breeding technology was evaluated. The candidate genes underlying qMtn-KJ-5D.1 were predicated based on multi-omics data information, and TraesKN5D01HG00080 is likely to be its candidate gene. Overall, our findings will be useful for elucidating the genetic architecture of tiller-related traits and developing novel wheat varieties with high yield.

Multifunctional black phosphorus/MoS₂ van der Waals heterojunction

Nanophotonics (2020)

Xixi Jiang Min Zhang Liwei Liu Xinyao Shi Yafen Yang

Abstract The fast-developing information technology has imposed an urgent need for effective solutions to overcome the limitations of integration density in chips with smaller size but higher performance. van der Waals heterojunctions built with two-dimensional (2D) semiconductors have been widely studied due to their 2D nature, and their unique electrical and photoelectronic properties are quite attractive in realizing multifunctional devices toward multitask applications. In this work, black phosphorus (BP)/MoS 2 heterojunctions have been used to build electronic devices with various functionalities. A p-n diode is achieved based on the vertically stacked BP/MoS 2 heterojunction exhibiting an ideal factor of 1.59, whereas a laterally stacked BP/MoS 2 heterojunction is implemented to fabricate a photodetector that shows a photodetection responsivity of 2000 mA/W at a wavelength of 1300 nm. Furthermore, a ternary inverter has been realized using a BP field-effect transistor in-series with a lateral BP/MoS 2 heterojunction. Such results have unambiguously demonstrated the superiority of BP/MoS 2 heterojunction in realizing multiple functionalities and have offered a new pathway for the design and engineering of future circuitry and device integration based on novel 2D semiconductors.

Metalorganic Chemical Vapor Deposition Heteroepitaxial β‐Ga₂O₃ and Black Phosphorus Pn Heterojunction for Solar‐Blind Ultraviolet and Infrared Dual‐Band Photodetector

physica status solidi (a) (2019)

Tao He Chang Li Xiaodong Zhang Yongjian Ma Xu Cao

Recently, β‐Ga 2 O 3 and black phosphorus (BP) have attracted enormous attention as the solar‐blind ultraviolet (UV) and infrared (IR) photosensitive materials for next‐generation optoelectronic devices, respectively, due to their special bandgap and electrical characteristics. Many β‐Ga 2 O 3 ‐based UV photodetectors and BP‐based IR photodetectors have been investigated separately, but there is no report on the heterojunction and photoelectric devices formed by these two excellent materials. Herein, metalorganic chemical vapor deposition (MOCVD) heteroepitaxial β‐Ga 2 O 3 and BP pn heterojunction for solar‐blind UV and IR dual‐band photodetector is proposed and demonstrated for the first time. The device demonstrates a remarkable photoresponse under UV and IR irradiations with a responsivity of 88.5 and 1.24 mA W −1 , respectively, clear pn heterojunction characteristics, as well as an excellent photoswitch periodicity. Moreover, under different irradiation conditions, the photoelectric properties of β‐Ga 2 O 3 /BP pn heterojunction, including their photogeneration and photoresponse, are investigated in detail. These results signify that β‐Ga 2 O 3 /BP pn heterojunction may find potential applications in future UV/IR dual‐band detection systems.

Characterization of a wheat stable QTL for spike length and its genetic effects on yield-related traits

BMC Plant Biology (2024)

Hongke Ding Chenyang Wang Yibiao Cai Kai Yu Haibo Zhao

Abstract Spike length (SL) is one of the most important agronomic traits affecting yield potential and stability in wheat. In this study, a major stable quantitative trait locus (QTL) for SL, i.e., qSl-2B , was detected in multiple environments in a recombinant inbred line (RIL) mapping population, KJ-RILs, derived from a cross between Kenong 9204 (KN9204) and Jing 411 (J411). The qSl-2B QTL was mapped to the 60.06–73.06 Mb region on chromosome 2B and could be identified in multiple mapping populations. An InDel molecular marker in the target region was developed based on a sequence analysis of the two parents. To further clarify the breeding use potential of qSl-2B , we analyzed its genetic effects and breeding selection effect using both the KJ-RIL population and a natural mapping population, which consisted of 316 breeding varieties/advanced lines. The results showed that the qSl-2B alleles from KN9204 showed inconsistent genetic effects on SL in the two mapping populations. Moreover, in the KJ-RILs population, the additive effects analysis of qSl-2B showed that additive effect was higher when both qSl-2D and qSl-5A harbor negative alleles under LN and HN. In China, a moderate selection utilization rate for qSl-2B was found in the Huanghuai winter wheat area and the selective utilization rate for qSl-2B continues to increase. The above findings provided a foundation for the genetic improvement of wheat SL in the future via molecular breeding strategies.

Acta Physica Sinica (2020)

Qiang Yu Kun Guo Jie Chen Tao Wang Jin Wang

As a member of the metal phosphorus trichalcogenide family, MPS3 is widely used in nonlinear optics and devices, which can be regarded as a significant benefit for the excellent photonic and optoelectronic properties. In this work, the MnPS3 nanosheet is prepared by the chemical vapor transport method and the MnPS3 saturable absorber is demonstrated by modifying mechanical exfoliation. To the best of our knowledge, the dual-wavelength self-starting mode-locking erbium-doped fiber laser with MnPS3 saturable absorber is demonstrated for the first time. The dual wavelength mode-locked laser with a pulse repetition rate of 5.102 MHz at 1565.19 nm and 1565.63 nm is proposed. Its maximum output power at the dual-wavelength is 27.2 MW. The mode-locked laser can self-start and stably run for more than 280 h.
