However, the interactions such as the hydrogen bonds among the acid-modified MWNTs caused a compact stacking morphology, resulting in a worse dispersion in PA6 matrix.
Further diamine modification on the acid-modified MWNTs could graft diamine molecules onto the surface of MWNTs, which weakened the interactions among the MWNTs and thus resulted in a less compact stacking morphology compared with acid-modified MWNTs.
The stacking of nucleosomes bring into close proximity residues H2A–(A53, E56, E64), H2B–(Q44, V45, E110) of one nucleosome with H3–(E73, Q76, D77), H4–(K20, L22, R23) of the neighboring nucleosome so that specific interactions between them can occur upon nucleosome gaping [36] and potentially lock the fiber in a compact state [8], [22] (see Fig. 4).
After that, we designed a compact fuel and air manifold by adopting a simulation technique to uniformly supply fuel and air gas into the stack and a unique seal and insulation method to make a more compact stack.
For a compact triangular stack (dense globular packing) the parameter K = 0.58 and the static friction coefficient for sand was found to be about 0.7 [23].
To simplify the practical flow pattern in the micro-porous media, a specific micro-channel is assumed with a compact spherical stacking-up model.
If compact fuel cell stacks of size ranging from 200 to 300 W can be produced comfortably, the SSE's can be encouraged to set up manufacturing units and they can become original equipment manufacturer (OEM) supplier to system integrators who could develop fuel cell systems of various capacities by simply connecting these compact stacks electrically in series or parallel depending on the end use.
In HeLa cells the Golgi comprises a compact array of stacks positioned close to the MTOC on one side of the nucleus.
