Broadband photodetectors based on narrow bandgap 2D materials have garnered considerable interest for application in the field of optoelectronic devices. However, their large dark current hinders device performance. In this work, a PtSe2/MoS2heterojunction was fabricated for a broadband photodetector operating within the range of visible to near-infrared. The device exhibited suppressed dark currents with a high rectification ratio of 104. The built-in electric field of the heterojunction promoted carrier separation effectively, and the device achieved excellent photoelectric performance with responsivities of 1.7 × 103,27.52, and 21 mA/W at 635, 785, and 1550 nm wavelengths, respectively. Moreover, the specific detectivities(D*) were 2.2 × 1013Jones(635 nm), 3.55 × 1011Jones(785 nm), and 2.72 × 108Jones(1550 nm). The device demonstrated a rise/fall time of 131/241 μs under 1550 nm laser illumination. Visible and near-infrared imaging detection was also demonstrated based on the heterojunction device at room temperature. This work sheds light on the remarkable potential of PtSe2/MoS2heterojunctions in the domain of high-performance broadband photodetectors.

Soybean, a crucial global leguminous crop, confronts persistent threats from diverse pathogens, exerting a profound impact on global *** genetic dimensions of soybean-pathogen interactions have garnered attention, the intricate biochemical responses remain poorly elucidated. In this study, we applied targeted and untargeted liquid chromatography coupled to mass spectrometry(LC-MS) metabolite profiling to dissect the complex interplay between soybeans and five distinct pathogens. Our analysis uncovered 627 idMS/MS spectra,leading to the identification of four main modules, encompassing flavonoids, isoflavonoids, triterpenoids, and amino acids and peptides,alongside other compounds such as phenolics. Profound shifts were observed in both primary and secondary metabolism in response to pathogenic infections. Particularly notable were the bidirectional changes in total flavonoids across diverse pathogenic inoculations, while triterpenoids exhibited a general declining trend. Noteworthy among the highly inducible total flavonoids were known representative antipathogen compounds(glyceollin I), backbone forms of isoflavonoids(daidzein, genistein, glycitein, formononetin), and newly purified compounds in this study(prunin). Subsequently, we delved into the biological roles of these five compounds, validating their diverse functions against pathogens: prunin significantly inhibited the vegetative growth and virulence of Phytophthora sojae; genistein exhibited a pronounced inhibitory effect on the vegetative growth and virulence of Phomopsis longicolla; daidzein and formononetin displayed significant repressive effects on the virulence of P. longicolla. This study underscores the potent utility of metabolomic tools, providing in-depth insights into plant-pathogen interactions from a biochemical perspective. The findings not only contribute to plant pathology but also offer strategic pathways for bolstering plant resistance against diseases on a broader scale.

设计了一个三羧酸柔性配体L,其可提供捕获镧系金属的亲和力及调节配体的能级,并可用于合成同时具有高稳定性和双发射特性的柔性镧系金属有机骨架(Eu-MOF)材料。利用柔性配体到金属的不完全能量转移使得材料出现350 nm和623 nm处的强双发射,构筑了比例荧光传感平台。由于柔性配体不稳定的电子构型以及Eu^(3+)和Fe^(3+)之间的离子交换,Eu-MOF可用于对Fe^(3+)的比例荧光检测。Eu-MOF对Fe^(3+)的检出限为0.592μmol/L,并分别在1.0~60.0μmol/L和60.0~90.0μmol/L范围内呈线性关系,响应时间低至3 min。Eu-MOF对Fe^(3+)检测具有良好的选择性、抗干扰性以及可回收性,用于实际样品中Fe^(3+)检测,加标回收率为98.4%~102.6%。

贡献模态法是一种适用于既有索杆张力结构刚度监测的静力位移扩展方法。为了提高静力位移的测试精度,提出一种针对每一阶贡献模态广义位移进行专门测量的误差控制策略。采用蒙特卡洛法分析贡献模态广义位移的误差上界分布规律,发现贡献模态广义位移越大其估计误差上界越小。以最大化指定荷载某阶贡献模态的广义位移作为优化目标,采用Jaya算法寻找包含该阶贡献模态的最优测试荷载(包括作用位置和大小)。将最优测试荷载施加于实际结构进行静力测试,得到最优测试荷载作用下该阶贡献模态广义位移的估计值,再采用间接测量的方式进一步计算出指定荷载作用下该阶贡献模态的广义位移。针对指定荷载各阶贡献模态依次展开测试荷载优化以及广义位移间接测量,可实现指定荷载作用下静力位移的测试及其误差控制。某索穹顶数值分析结果表明,文中方法可以大幅降低竖向荷载作用下静力位移的测试误差上界,从而为索杆张力结构的挠度校核、模型修正、预应力识别等后续工作提供较多的高质量测试数据。
