Also, cross bonding between two carbon chains, 5 nm long, is observed experimentally and confirmed by DFT calculations.
Double bond explicitly marked by user as unknown (cross bonds).
It was provided with a 50 m × 0.32 mm Rtx®−1 (Cross bond 100 % Dimethyl-polysiloxane) column.
The volumetric reduction that occurs because of cross bonding between the molecules in the CR organic matrix would be reduced in silorane-based CR due to the opening of a cationic ring previously to the formations of such chemical bonds, during the material polymerization [18, 19, 49, 50].
Ethanol was estimated by gas chromatography (GC) (Perkin Elmer, Clarus 500) with an elite-wax (cross bond-polyethylene glycol) column (30.0 m × 0.25 mm), at oven temperature 90°C and flame ionization detector (FID) at 200°C.
In particular, inter-core mode propagation is substantially affected by the cross-bonding of sheaths.
In the exocuticle there is cross-bonding of the chitin protein chains (tanning), which provides additional strength to the skeletal material.
Some chemical structure drawing programs allow users to specify double bond stereochemistry in an "either" form (commonly represented as a crossed bond) or as specifically defined E/Z stereo.
Therefore, we only consider those secondary structures that do not contain pseudoknots, crossing bonds and zigzags.
A Restek Stabilwax-DA (cross-bond PEG treated with nitroterephthalic acid) open tubular capillary column (30 m × 0.32 mm × 0.50 μm) was used for separation.
The notion k-noncrossing stipulates that the complexity of a pseudoknot is related to the maximal number of mutually crossing bonds.
