In order to design a proper modified reactor by mean of an installation of such mixing structures for the pilot plant in liquid fuel production via Fischer-Tropsch Synthesis (FTS) conducted at the RCC research center, this study had to characterize the hydrodynamics and heat transfers within a packed-bed modified by KenicsTM and Mixing & Stirring type static mixers.
Fig. 3 demonstrated the flow structures within the computational domain as a result of mixed gas stream passing through the packed bed and those installed with static mixers.

Future study will reveal the relationship between specific structures and functions for molecular design of novel biomimetic underwater adhesives.
Finally, the relationship between specific structures and functions of recombinant Bacp-19k will be discussed to reveal the curing mechanisms, for molecular design novel adhesive peptides [15, 17].

Our laboratory and others have previously reported that substrate topography, independent of surface chemistry, profoundly modulates fundamental cell behaviors.
In the vertebrate body, basement membranes are specializations of the extracellular matrix that serve as the substrate upon which many overlying cellular structures grow.
Briefly a hard-poly(dimethylsiloxane) (hPDMS) stamp [22, 23] was molded from a silicon master, and then the relief structures of the hPDMS stamp were in turn molded into the surfaces of transparent thin films of an ultra violet photo-cross-linkable polyurethane (Norland Optical Adhesive 81, Summers, NJ) supported on glass cover slips or tissue culture polystyrene.
The first is topographically mediated alteration of adhesion structures which, in turn, may lead to changes in signal transduction from integrins, FAK, p130Cas, Rho, Rac, etc.

Rice husks were chosen as eco-friendly materials to replace commercial precursors because of their abundance, the same orthosilicate structure, and the high purity of silica.
With a solid structure and a diameter ranging from 2 to 50 nm, MSN possesses unique properties such as thermal stability, good biocompatibility, and ease of surface modification [1].
Rice husks are a prime example of this with their abundance, high silica purity, and shared orthosilicate structure with TEOS [14].

Transmission electron microscopy (TEM) of as quenched condition revealed fully martensite structure in the alloy.
The TEM micrographs of 150 °C for 4 h tempered sample shows and conforms the very fine carbide precipitation in the microstructure (Fig. 3a) with some amount of untempered martensite (Fig. 3c) as evidenced partly by clear martensite lath structure.

As compared with traditional are spraying technology, the high velocity arc spraying technology has such advantages as higher stability, higher processing efficiency and the coating has more compact structure.
The intelligentized self-repairing technology is a kind of technology that bases on the intelligentized biology technology and micro-nano technology, through the friction chemistry between the metal substrates and self-repairing materials, a reaction thin film with good friction reduction and self-repairing performance is formed on the worn surface, a dynamical equilibrium is achieved between wear and dynamic repair, and the self-repairing on the worn surface is realized without disassembly and shut down of the machine.
