The Influence of Superstrong Magnetic Fields on Thermonuclear Reaction at the Outer Crust of Magnetar [PDF]

open access: yes, 2016
核天体物理领域中超强磁场的相关研究表明:磁星外壳层热核反应都与磁场密切相关。磁星的超强磁场不仅影响热核反应率和最终元素丰度,而且还影响磁星的中微子能量损失率,最终影响其演化时标、演化进程和冷却机制。由于超强磁场的重要性,本文主要研究了磁星表面壳层超强磁场对一些典型核素的热核反应的影响。 首先,基于相对论性的超强磁场理论(Fushikietal.1989),利用Thomas-Fermi-Dirac近似方法,我们研究分析了超强磁场环境电荷屏蔽难题,讨论了电荷屏蔽对热核反应23Mg(p,gamma ...

Assembly of Oriented Cellulose Nanocrystal Thin Films and Their Applications in Controllable Fabrication of Composites [PDF]

open access: yes, 2016
纤维素纳米晶体(CNC)是一种新兴的一维纳米材料,由于具有密度低、长径比可调、高弹性模量和高强度、生物相容性好以及丰富的组装行为等优点在先进功能材料、光电子器件、医疗设备等重要领域应用前景广阔。其性能与组装行为,尤其是宏观尺度上的组装结构密切相关。CNC的单轴取向组装体可实现基于溶液法的功能化薄膜材料的低成本制备。然而,迄今为止,很少研究者能够提供可靠的方案获得宏观尺度有序的密堆积CNC组装体,从而限制了CNC基的组装体在众多功能材料和器件中的广泛应用。因此 ...
