Morphology and Precipitation Kinetics of MnS in Low-Carbon Steel During Thin Slab Continuous Casting Process

引用

Journal of Iron and Steel Research International 2006年第5期13卷 30-36页

作者： YU hao KANG yong-lin Zhao Zheng-zhi SUN hao School of Materials Science and Engineering University of Science and Technology Beijing Beijing 100083 China Jinan Iron and Steel Technical Center Jinan Iron and Steel Group Co Jinan 250101 Shandong China

The morphology of manganese sulfide formed during thin slab continuous casting process in low-carbon steel produced by compact strip production （CSP） technique was investigated. Using transmission electron microscopy analysis, it was seen that a majority of manganese sulfides precipitated at austenite grain boundaries, the morphologies of which were spherical or close to the spherical shape and the size of MnS precipitates ranged from 30 nm to 100 nm. A mathematical model of the manganese sulfide precipitation in this process was developed based on classical nucleation theory. Under the given conditions, the starting and finishing precipitation temperatures of MnS in the continuous casting thin slab of the studied low-carbon steel are 1 189 ℃ and 1 171 ℃, respectively, and the average diameter of MnS precipitates is about 48 nm within this precipitation temperature range. The influences of chemical components and thermo-mechanical processing conditions on the precipitation behavior of MnS in the same process were also discussed.

Non-detection of pulsed radio emission from magnetar Swift J1834.9-0846: constraint on the fundamental plane of magnetar radio emission

引用

Research in Astronomy and Astrophysics 2013年第7期13卷 835-840页

作者： hao Tong Jian-Ping Yuan zhi-yong Liu Xinjiang Astronomical Observatory Chinese Academy of Sciences

The magnetar Swift J1834.9-0846 is observed using the Nanshan 25 m radio telescope. No pulsed radio emission is detected. The upper limit on the pulsed radio emission from this source is 0.5 mJy. According to the ＂fundamental plane＂ for radio magnetars, this source should have radio emission. Therefore, our results put constraints on the existence of a fundamental plane of magnetar radio emission. We argue that a magnetar＇s ability to emit radio emission may have little to do with the spin down luminosity and is related to the magnetar＇s X-ray luminosity. The only necessary condition is a relatively low X-ray luminosity.

Laser-Induced Highly Stable Conductive Hydrogels for Robust Bioelectronics

引用

NANO-MICRO LETTERS 2025年第1期17卷 1-4页

作者： Li, Yibo Zhou, hao Yang, Huayong Xu, Kaichen Zhejiang Univ Sch Mech Engn State Key Lab Fluid Power & Mechatron Syst Hangzhou 310058 Peoples R China

Despite the promising progress in conductive hydrogels made with pure conducting polymer, great challenges remain in the interface adhesion and robustness in long-term monitoring. To address these challenges, Prof. Seung Hwan Ko and Taek-Soo Kim's team introduced a laser-induced phase separation and adhesion method for fabricating conductive hydrogels consisting of pure poly(3,4-ethylenedioxythiophene):polystyrene sulfonate on polymer substrates. The laser-induced phase separation and adhesion treated conducting polymers can be selectively transformed into conductive hydrogels that exhibit wet conductivities of 101.4 S cm-1 with a spatial resolution down to 5 mu m. Moreover, they maintain impedance and charge-storage capacity even after 1 h of sonication. The micropatterned electrode arrays demonstrate their potential in long-term in vivo signal recordings, highlighting their promising role in the field of bioelectronics.
