分子自组装是指无序分子自发形成有序且稳定的结构的一种行为。我们构建了一种新型的基于石墨烯的金刚石基底平台,经过特殊工艺处理,使其具有优异的光学透明性和一定的导电性。基于该基底的特性,我们在大气环境下通过扫描隧道显微镜对一组双成分的超分子进行了研究,表明其可通过每两个分子间的三重氢键的相互作用力在石墨烯-金刚石基底上形成稳定的自组装结构。同时,系统整体的驱动力是通过分子间的氢键作用和分子与基底间的范
近来,聚合物太阳能电池的光伏效率显著提高.但要想实现产业化应用,稳定性是必需考虑的因素之一.反向结构器件可避免酸性PEDOT:PSS对ITO的腐蚀作用,并且使用高功函顶电极,从而提高了器件稳定性.透明ITO玻璃电极功函比较高,不能直接用作电池负极收集电子. 周印华等[1]利用非共轭的PEI,PEIE旋涂于电极表面,使得电极的功函大大降低,器件效率相对提高.受他们工作的启发,为了进一步提高修饰层的稳
In this work we will introduce a new hybrid scheme to discretize the advection-diffusion-reaction equation.
In this paper,we will develop a fast iterative solver for the system of equations arising from the local discontinuous Galerkin(LDG)spatial discretization and implicit time marching method for high or
In-depth understanding toward the mechanism is the focus of our current research.Recently,a new series of oxidative coupling reactions have been developed.New insights into the reaction mechanism have
双环化合物是天然产物和药物分子中的优势核心骨架,合成这些分子面临的挑战是如何高效地构建目标分子中的环系骨架。考虑最终产物中要去除金属杂质的困难性,有机催化的合成双环化合物方法是一个有效的途径。有机膦催化的Domino反应是一个构筑各种环状化合物的有效平台,主要用在单环的合成,我们发现联烯可以作为新的1,2,3-C3和1,2,4-C3合成子,通过底物调控,催化剂调控,催化模式调控可以实现目标产物的调

In this talk,I will report our recent work of a class of central compact schemes with spectral-like resolution.Combining the technique of Lele s linear compact scheme and WENO interpolation,we develop
This talk focuses on discrete double/single-curl operators in Maxwells equations for 3D photonic crystals,chiral and pseudochiral complex media with face centered cubic lattices.
We consider nonstandard Petrov–Galerkin discretizations of linear problems in Banach spaces.
