| 1 | Wear behavior of Zn-38Al-3.5Cu-1.2Mg/SiC_(p) composite under different stabilization treatments显示文摘A Zn-38Al-3.5Cu-1.2Mg composite reinforced with nano-SiC_(p) was fabricated via stirring-assisted ultrasonic vibration.To improve the abrasive resistance of the Zn-38Al-3.5Cu-1.2Mg/SiC_(p) composite,several stabilization treatments with distinct solid solutions and aging temperatures were designed.The results indicated that the optimal stabilization treatment for the Zn-38Al-3.5Cu-1.2Mg/SiC_(p) composite comprised solution treatment at 380℃for 6 h and aging at 170℃for 48 h.The stabilization treatment led to the formation of dispersive and homogeneous nano-SiC_(p).During the friction wear condition,the nano-SiC_(p) limited the microstructure evolution from the hardα(Al,Zn)phase to the softβ(Al,Zn)phase.Moreover,the increased amount of nano-SiC_(p) improved the grain dimension and contributed to the composite abrasive resistance.Furthermore,the stabilization treatment suppressed the crack initiation and propagation in the friction wear process,thereby improving the abrasive resistance of the Zn-38Al-3.5Cu-1.2Mg/SiC_(p) composite. | Sheng Liu Qing Yuan Yutong Sima Chenxi Liu Fang Han Wenwei Qiao | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，6： | 0 |
| 2 | Molecular imaging:design mechanism and bioapplications显示文摘Molecular imaging is a non-invasive method to image and analyze the concentration and activity of functional biomolecules in cells or in vivo at molecular level,and plays an increasing role in deep understanding of biological processes,early and accurate diagnosis of diseases,and evaluation of treatment.Nowadays,numerous novel molecular imaging probes have been developed,involving every biomedical imaging modality,such as optical imaging,photoacoustic imaging,magnetic resonance imaging,single-photon-emission computed tomography,and positron emission tomography.In this review,we summarize the development of current state-of-the-art molecular imaging probes.We introduce the design strategies of molecular probes and detailed imaging modalities,and highlight the properties of probes and biomedical imaging applications in cells and in vivo,including disease diagnosis,drug tracking,and imaging-guided surgery.Then we discuss the perspectives and challenges in this emerging field.We expect this review could inspire more effective molecular imaging probes to be developed,achieving the goal towards clinical practices. | Lanlan Chen Yifan Lyu Xuan Zhang Liting Zheng Qingqing Li Ding Ding Fengming Chen Yihao Liu Wei Li Yutong Zhang Qiuling Huang Zhiqiang Wang Tiantian Xie Qiang Zhang Yingyu Sima Ke Li Shuai Xu Tianbing Ren Mengyi Xiong Ying Wu Jibin Song Lin Yuan Huanghao Yang Xiao-Bing Zhang Weihong Tan | 2023 | Science China Chemistry2023，66，5： | 0 |
