During the interval from 0615-0730UT on 24 August 2005, the near-Earth magnetotail displayed multiple responses to the combined changes in solar wind dynamic pressure and interplanetary magnetic field (ImF). The magnetotail was highly compressed by a strong interplanetary shock due to the dynamic pressure enhancement (5nPa), and the large shrinkage of magnetotail made a northern lobe/mantle move inward to the position of inbound TC1 satellite that was initially in the plasma sheet. meanwhile, the dynamic pressure fluctuation behind the shock drove the quasi-periodic oscillations of the magnetopause, lobe-mantle boundary and geomagnetic field at the same frequencies, one dominant frequency is around 3mhz and the other is around 5mhz. The oscillation of the lobe-mantle boundary caused the alternate entries of TC1 into the northern lobe and the plasma mantle. In contrast to a single squeezed/deformed magnetotail by a solar wind discontinuity moving tailward, the compressed and oscillating magnetotail can better indicate the dynamic evolution of magnetotail when solar wind dynamic pressure increases and fluctuates remarkably. Furthermore, it is found that the considerable oxygen ions (O+) appeared in the lobe after the southward turning of ImF.

This paper addresses the deveolopment of a magneto-elastic coupling dynamic hysteresis model for giant magnetostrictive materials(Gmms).Firstly,a three-dimensional domain rotation mechanism is introduced to investigate how the magnetization and magnetostriction of Gmms change with stresses and applied magnetic *** eddy current effects are incorporated to predict the dynamic hystersis behaviour of *** study reveals that eddy current losses lead to increaseing magnetic hysteresis as the frequency *** model is validated by comparing the predicted results with experiment ***,the model is convenient to be used in engineering applications since the parameters referred to the model have definite physical meaning and can be easily determined by experiments.

Carbon for Reliable Lithium-Sulfur Batteries

中国化学会2019能源材料和缺陷化学研讨会

作者： RP Fang GJ hu Zh Sun h-m Cheng F Li Institute of metal Research Chinese Academy of Sciences

Lithium-sulfur（Li-S） batteries have attracted tremendous interest because of their high theoretical energy density and cost effectiveness.1, 2 The object of Li-S battery research is to produce batteries with more high energy density that at least outperforms state-of-the-art lithium-ion batteries. however, due to an intrinsic gap between fundamental research and practical applications, the outstanding electrochemical results obtained in most Li-S battery studies indeed correspond to low useful energy densities and are not really suitable for practical requirements.3 The Li-S battery is a complex device and its useful energy density is determined by several key parameters, most of which are often ignored, leading to the failure to meet commercial requirements.4 The purpose of this talk is to discuss how to pave the way for a reliable Li-S battery. From the perspective of fundamental research, high sulfur contents, high areal sulfur loadings and low electrolyte-to-sulfur ratios are essential requirements for achieving high practical energy density of a Li-S device. Possible solutions and some concerns regarding the optimization of these parameters are comprehensively discussed. Besides, problems related to a lithium metal anode in the Li-S system remain a great challenge and further developments are needed for the stabilization and protection of the anode. Finally, the future directions and prospects in Li-S battery field are considered.

过去25年来,大量研究报道了外源酶在单胃动物饲料中的应用。人们发现商品化植酸酶的使用效果与实验室结果并非完全一致。其中,很多研究认为植酸酶的应用与肉鸡垫料潮湿有关。解决的重点是通过改变日粮的成分,添加植酸酶来减少肉鸡垫料潮湿的发生。早期文献中提及的非淀粉多糖酶在体内的作用机制随着实践的检验，很多内容逐渐被证明不正确。尽管这些新的认识在商业化应用中取得的效果并非很明显，但随着新的产品的开发和应用，人们会慢慢接受。本文主要针对植酸酶和非淀粉多糖酶的应用进行阐述。
