Hybridization, natural

The hybridic nature of the Si—H bond is utili2ed to generate C—H bonds by ionic hydrogenation according to the foUowiag general mechanism, ia which a hydride is transferred to a carbocation. 

D microfabricated reactor devices are typically made by fabrication techniques other than stemming from microelectronics, e.g. by modern precision engineering techniques, laser ablation, wet-chemical steel etching or pEDM techniques. Besides having this origin only, these devices may also be of hybrid nature, containing parts made by the above-mentioned techniques and by microelectronic methods. Typical materials are metals, stainless steel, ceramics and polymers or, in the hybrid case, combinations of these materials.

This technique is used for packaging and industrial multilayer films, often of hybrid nature associating a thermoplastic with paper, cardboard, aluminium foil... Some applications are, for example, barrier films, anti-adherent films, credit cards, wallpapers. .. 

The hybrid nature of these films leads to several main advantages ... 

The relationship between elimination half-life (h/2) body weight across species results in poor correlation, most probably because of the hybrid nature of this parameter [27]. A better approach may be to estimate volume of distribution and clearance by the most appropriate method and then estimate half-life indirectly from the relationship ...

A rearrangement of Formula 141 analogous to the rearrangement of Formula 143 to Formula 144 is not detectable because the result is an identity. The intermediate analogous to Formula 155 has a plane of symmetry because of the hybrid nature of the allyl radical.

Further uses of pseudopotentials are numerous. The most obvious (and rather widely known ones) are to continue with the PP or MP Hamiltonians for a widely understood combination of the core and valence shells and to apply standard ab initio techniques to electrons in the valence subspace only. We do no elaborate further on this as the hybrid nature of the pseudopotential methods is rather obvious from the above and its more specific applications in a narrower QM/MM hybrid context will be described later. 

In the previous section we described existing HFR-based semiempirical methods and demonstrated their hybrid nature in a wide sense. We have also shown that for certain physical situations the semiempirical methods may become invalid due to the necessity to explicitly address nontrivial electronic correlations manifesting themselves either in numerous Slater determinants to be included in the consideration or in nonvanishing matrix elements of the cumulant of two-electron density matrix whose presence must be somehow reproduced in the calculation. 

The higher C—N force constant for the former might be ascribed to the sf hybrid nature of the orbital of the ring carbon atom used for C—N bond formation as against the sp hybrid nature of the corresponding orbital in the latter case.

We are nowhere close to knowing the potential benefits that nanoscale silicone resin networks, with their special structure-effect relationship, will be able to offer irmovative technologies of the future (nanotechnology). By virtue of their organic-inorganic hybrid nature, silicones open up new paths to special functionalities and enhanced properties of materials. 

Thus the hybrid nature of the allyl cation governs both steps of electrophilic addition to conjugated dienes the hrst, through stabilization the second, by permitting attachment to either of two carbon atoms.
