Metal–Metal Bonding

open access: yes, 2013
This chapter deals with the electronic structure of metal-metal bonds in molecular systems, a diverse topic that now spans almost the entire periodic table. The field is most often associated with strong multiple bonds such as the iconic quadruple bond in [Re2Cl8]2-, and the recently discovered ultra-short Cr-Cr quintuple bonds provide a remarkable ...

Surface metallization and application of ultra-high molecular weight polyethylene fiber

open access: yesShenzhen Daxue xuebao. Ligong ban
Ultra-high molecular weight polyethylene (UHMWPE) fibers and fabrics suffer from weak interfacial bonding with composite matrix due to their chemically inert surface and high crystallinity, thereby affecting the performance of composite materials.

Amorphous-like TiN Films as Barrier Layers for Copper

open access: yesCrystals
The titanium nitride (TiN) columnar structure results in a rapid diffusion of copper atoms into the substrate along a vertical path. In this paper, the TiN columnar growth process was modified, which resulted in the deposition of amorphous-like films ...

Metal-metal bond lengths in complexes of transition metals [PDF]

open access: yesProceedings of the National Academy of Sciences, 1976
In complexes of the transition metals containing clusters of metal atoms the cobalt-cobalt bond lengths are almost always within 1 pm of the single-bond value 246 pm given by the enneacovalent radius of cobalt, whereas most of the observed iron-iron bond lengths are significantly larger than the single-bond value 248 pm, the mean ...
