Over the past 70 years, the semiconductor industry has undergone transformative changes,largely driven by the miniaturization of devices and the integration of innovative structures and materials. Two-dimensional(2D) materials like transition metal dichalcogenides(TMDs) and graphene are pivotal in overcoming the limitations of silicon-based technologies, offering innovative approaches in transistor design and functionality, enabling atomic-thin channel transistors and monolithic 3D integration. We review the important progress in the application of 2D materials in future information technology, focusing in particular on microelectronics and optoelectronics. We comprehensively summarize the key advancements across material production, characterization metrology, electronic devices, optoelectronic devices, and heterogeneous integration on silicon. A strategic roadmap and key challenges for the transition of 2D materials from basic research to industrial development are outlined. To facilitate such a transition, key technologies and tools dedicated to 2D materials must be developed to meet industrial standards, and the employment of AI in material growth, characterizations, and circuit design will be essential. It is time for academia to actively engage with industry to drive the next 10 years of 2D material research.

中山杉(Taxodium hybrid'zhongshanshan')是落羽杉属种间杂交良种,有突出的经济价值、生态价值和美学价值。通过引进邻近地区江苏等地中山杉良株在鲁南地区连续多年观察物候期,开展异地栽植试验研究的结果表明:春季解冻后,移栽时间越早成活率越高,2月20日前后是鲁南地区最适宜时间。在生根粉浓度相同的条件下,沙壤地成活率(95.67%)高于粘壤地和棕壤地成活率(92.67%和87.00%);沙壤地最佳生根粉浓度为45μg/kg,粘壤地最佳生根粉浓度为75μg/kg。

目前,临床医学应用与基础医学研究之间缺乏衔接,在强烈的需求下一种新的医学发展模式一一转化医学应运而生,致力于填补基础与临床之间的鸿沟,最终目的是满足患者的健康需要、保障人类健康。传统的中医药学具有从临床到理论再到临床循环式的研究路径,与转化医学存在相同的理念和治疗方法。因此,需要通过建立中医学转化研究中心,加强转化医学推广教育和转化型人才培养,加大扶持力度与政策引导两者结合,这将会对中医药的创新发展有着重大意义。
