Polar coordinates at the crack tip. In fracture mechanics, the stress intensity factor (K) is used to predict the stress state ("stress intensity") near the tip of a crack or notch caused by a remote load or residual stresses. [1]
SiH 3 Br + 2 Me 2 NH → SiH 3 NMe 2 + Me 2 NH 2 Br 4 SiH 3 I + 5 N 2 H 4 → (SiH 3) 2 NN(SiH 3) 2 + 4 N 2 H 5 I. Many such compounds have been prepared, the only known restriction being that the nitrogen is always tertiary, and species containing the SiH–NH group are unstable at room temperature. The stoichiometry around the nitrogen atom ...
A number of computational studies have been performed on these systems. A sample paper from 2000 employed NBO to analyze a series of related complexes. Taking [(CO) 4 Fe{BN(SiH 3) 2}] as an example, it was calculated that—as expected—the boron moiety is relatively electron-poor (+0.59 charge). The Fe-B π-bonding orbitals were found to have ...
These hydrides decompose to SiH when heated to 750 K. [2] Other ways to coat a silicon surface in hydrogen is via reaction with atomic hydrogen, or hot silane. [3] A (111) crystal face will become covered in the pure monohydride, but other faces on a silicon crystal will also have the dihydride and trihydride groups.
Silane SiH 4, the parent. Binary silicon-hydrogen compounds (which are sometimes called silanes also) includes silane itself but also compounds with Si-Si bonds including disilane and longer chains. Silanes with one, two, three, or four Si-H bonds are called hydrosilanes. Silane is again the parent member. Examples: triethylsilane (HSi(C 2 H 5)

Bis(trimethylsilyl)amine (also known as hexamethyldisilazane and HMDS) is an organosilicon compound with the molecular formula [(CH 3) 3 Si] 2 NH. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms.
