We use comparative natural bond orbital (NBO) and quantum theory of atoms in molecules (QTAIM) methods to analyze the proximal bay-type H···H interactions in cis-2-butene and related species, which lead to controversial interpretation as attractive "HH bonding" in the QTAIM framework. We ...
We used density-functional theory to assess the electronic structure, elastic properties and planar fault energies of the B2 Ti(AlxNb1-x) (0.2 ≤ x ≤ 0.8) phase in relation to the composition and chemical ordering. We found that the covalent bonding becomes stronger for B2 Ti(AlxNb1-x) ...

The Young's modulus is in the order of HfB2ZB2NbB2TaB2YB2. As a results of these calculations, YB2 is predicted to have the best thermal shock resistance since it has the lowest Young's modulus. The brittleness, based on the calculated solidity index S=0.75G/B, is estimated in the...
The present invention is a method for bonding two surfaces without applying heat. The surfaces are prepared so that they both have an outermost layer of aluminum. One of the surfaces has metallized pa
This indicates that, in order to achieve high bonding energy, the released hydrogen must be removed from the bonding interface. Many prebonding treatments are available for low-temperature hydrophobic wafer bonding including the formation of an amorphous silicon layer byAs+implantation, byB2H6or Ar ...
There is a straight line throughout the welding interface, i.e., bonding line (BL) due to the severe pinning effect of O phase on Ti atoms. To eliminate the BL, many measures have been developed, such as increasing the bonding temperature to B2 phase field [5] or introducing the ...
The results shows that the multiple dimension grey fuzzy decision making pattern can not only be used to determine the weights of evaluating indexes, but also get the fuzzy partition and ranking order of the financial agglomeration in the central five cities. The grey prediction results can ...
1b and grips the wire lead at tip surface 16 which is generally in the order of 3 mils long on a side. Tip surface 16 grips the wire and wipes the wire against the contact to which the wire is to be bonded. If surface 16 has a relatively smooth surface having a microfinish less ...
