多层次自己组装(MHSA ) 是为许多复杂结构的自发的形成负责的一个关键过程。因为这个过程的复杂性，然而，内在的机制仍然保持大部分不清楚。因此， MHSA 的更深的理解被要求，特别为经由自底向上的方法论的 MHSA 系统的准备。我们这里，试验性地并且理论上出现，肽 nanotube 电影的复杂形成的 MHSA 能完全被操作湿度的试验性的参数控制。而且，我们识别生长前面成核(GFN；在周界的新谷物的形成) 词法进化作为为由有阶段地的相关试验性的观察的观察词法转变的物理背景当模特儿。我们的调查结果显示一个简单方法控制多层次的形态学，为在为实际应用程序构造复杂结构的自底向上的技术的雇用关键。
Nickel layer with different thickness is electroplated on the side surface of a Cu46Zr46Al8 bulk metallic glass. Electroplating time and current intensity has the most important influence on the coating thickness and quality. When electroplating time within 3 h and current intensity below 20 m A, the coating thickness…
Supercapacitors have high power density and long cycle life compared with battery systems, but they still suffer from low energy density at the same time. In order to increase the energy density of supercapacitors, a new type of pseudocapacitor so called colloidal ion supercapacitor has been developed. The colloidal i…
Ionic liquid( IL) 1-butyl-3-methylimidazolium chloride( [Bmim]Cl) was used to dissolve microcrystalline cellulose Avicel to make IL-regenerated cellulose membrane for papain immobilization through silane modification method. It demonstrated that the immobilized papain could be obtained at the condition of6. 5%( mass f…
Herein we demonstrate crystallization-driven self-assembly of isotactic polystyrene(i PS) with high isotacticity and narrow molecular weight distribution and crystallization-induced switching of the morphology of i PS aggregates in N, N-dimethylformamide(DMF). The formation and morphology switching of the self-assembl…
Hydrogen(H) defect interactions have been investigated by molecular statics simulations in tungsten(W),including H-H interactions and interactions between H and W selfinterstitial atoms.The interactions between H and small H-vacancy clusters are also demonstrated;the binding energies of an H,a vacancy and a self-inter…
Composition dependence of electrocaloric effect is investigated in(1- x)Pb(Mg1/3Nb2/3)O3- xP b Ti O3 single crystals by using an eighth-order Landau–Devonshire theory. The applied electric field along [001] direction reduces the ferroelectric-ferroelectric phase transition temperatures, but increases the Curie tempera…
