南黄海盆地位于下扬子地区的海域部分,其宏观地质背景与扬子陆域具有相似性。通过分析扬子陆域古生界烃源岩发育的沉积相带、岩性特征、地球化学指标等,结合南黄海盆地构造、沉积演化特征和已钻井揭示情况,指出南黄海盆地古生界发育下寒武统(幕府山组)、上奥陶统—下志留统(五峰组—高家边组)和二叠系(包括栖霞组、孤峰组、龙潭组及大隆组)三套主力烃源岩,并推测下寒武统和上二叠统烃源岩品质优于中、上扬子地区,总体上三套主要烃源岩均具有较好的生烃潜力。对扬子陆域已发现的大型油气田进行分析总结,提出“烃源充足-持续汇聚-构造稳定”是扬子地区形成大型油气田的关键成藏条件。南黄海盆地中部隆起古生界厚度大且分布稳定,沉积相分析表明其烃源条件好;印支期以来被南部和北部的新生代坳陷所夹持,且长期处于隆升状态,具有持续汇聚油气的古隆起背景;隆起区弱变形构造带和平缓构造带印支期以来构造稳定、断裂数量少,有利于油气保存,是探索中—古生界油气藏的有利地区。勿南沙隆起古生界厚度大,后期新生代断陷叠加范围小、断陷幅度小,有利于海相原生油气藏的发育和保存,也是中—古生界勘探潜力区。

Laminectomy is one of the most common posterior spinal operations. Since the lamina is adjacent to important tissues such as nerves, once damaged, it can cause serious com-plications and even lead to paralysis. In order to prevent the above injuries and com-plications, ultrasonic bone scalpel and surgical robots have been introduced into spinal laminectomy, and many scholars have studied the recognition method of the bone tissue status. Currently, almost all methods to achieve recognition of bone tissue are based on sensor signals collected by high‐precision sensors installed at the end of surgical robots. However, the previous methods could not accurately identify the state of spinal bone tissue. Innovatively, the identification of bone tissue status was regarded as a time series classification task, and the classification algorithm LSTM‐FCN was used to process fusion signals composed of force and cutting depth signals, thus achieving an accurate classi-fication of the lamina bone tissue status. In addition, it was verified that the accuracy of the proposed method could reach 98.85% in identifying the state of porcine spinal laminectomy. And the maximum penetration distance can be controlled within 0.6 mm, which is safe and can be used in practice.

One-pot and One-step Cu(0)-mediated Reversible-Deactivation Radical Polymerization of N-Isopropylacrylamide(NIPAM) in Water

引用

Chinese Journal of Polymer Science 2024年第1期42卷 1-6,I0004页

作者： Zi-Shan Li Jing Lyu Bei Qiu Ying-Hao Li Ruth Foley Ri-Jian Song Melissa Johnson Qiang geng Wen-Xin Wang Institute of Precision Medicine(AUST-IPM) Anhui University of Science and TechnologyHuainan 232001China Charles Institute of Dermatology School of MedicineUniversity College DublinDublin D04 V1W8Ireland

Copper(0)-mediated reversible-deactivation radical polymerization(Cu(0)-mediated RDRP) of the water-soluble monomer Nisopropylacrylamide(NIPAM) has been challenging with the problems of high dispersity, poor control over the molecular weights(MWs) or complex or multi reaction steps, etc. In this work, we report the well-controlled polymerization of NIPAM in water via a facile one-pot and one-step Cu(0)-mediated RDRP. The results of this approach show that the key for kicking off the Cu(0)-mediated NIPAM RDRPs is to ensure sufficient Cu~I at the very beginning, and the key to achieve a well-controlled chain growth is to provide adequate deactivation strength during the polymerization process. For NIPAM, which has a high propagation rate constant, the deactivation control can be effectively enhanced by extra adding deactivator(i.e., Cu~II) to the system. Moreover, a low reaction temperature(4 ℃) is necessary in the controlled synthesis of higher MW poly(Nisopropylacrylamide)(PNIPAM) to avoid the compromise in control caused by the phase transition from its lower critical solution temperature(LCST). Through this new kinetically controlled strategy, PNIPAMs with well-defined structure, narrow molecular weight distributions(MWDs) and varied MWs were successfully achieved.
