Without directional bonding, how can you explain the property of ionic crystals that, when struck with a sharp blow, the crystal will fall apart? Logged Donaldson Tan Editor, New Asia Republic Retired Staff Sr. Member Posts: 3177 Mole Snacks: +261/-13 Gender: Re:Directional vs non-direct...
受Abell启发,Tersoff意识到Si体系势能很大程度取决于BO,而BO由原子的local environment决定,因此可以尝试把local geometry parameters写成解析形式,再包含到potential function里去,就得到有物理基础同时可以描述directional bonding的势能形式。他探索出来的一种形式如下, 其中f_c 是截断函数, f_R 和f_A 分别为排斥势和...
transition metals, dislocation core, central forces, directional bonding, asymmetry of glideIn this paper, we address the differences between Finnis–Sinclair potentials and bond-order potentials (BOPs) when studying 1/2111 screw dislocations in bcc transition metals, specifically Mo and W. These two...
aBecause cleavage is a directional characteristic of weak atom bonding, any direction in a crystal lying parallel to layers of atoms is a potential cleavage direction, although most minerals resist splitting along these various planes. 由于分裂是微弱的原子接合的一个方向特征,所有方向在水晶说谎平行与原...
Here we demonstrate how the unique directional bonding and varying basicity of the decaniobate ([Nb10]) oxoヽaps can be exploited to build 1D, 2D, and 3D inorganic frameworks. In nine structures, A+ (A=Li, Na, K, Rb and Cs), AE2+ (AE=Ca, Sr, Ba) and Mn2+ demonstrate that the...

Structure and bonding energy analysis of M-Ga bonds in dihalogallyl complexes trans-[X(PMe3)2M(GaX2)] (M = Ni, Pd, Pt; X = Cl, Br, I). Geometry, electronic structure, and bonding analysis of the terminal neutral dihalogallyl complexes of nickel, palladium, and platinum trans-[X(...
Our rational design strategy leads to systems that robustly assemble in simulations into a target IQC through directional bonding. This is illustrated for both body-centred and primitive IQCs, with the simplest systems involving just two particle types. The key design feature is the geometry of ...
the salt-bridges and non-bonded interactions collectively enhance the stability of the Vt:F-actin complex under mechanical force. Our multi-faceted approach in the current study underscores the complexity of catch bonding, emphasizing the importance of considering a range of interaction types to compre...
