In order to sustain attachment, spreading, and orientation of human CMs on a scaffold we exploited an innovative negative replica patterning based on electrophoretic deposition to realize multi-scale micro-structured chitosan-collagen (C/C) scaffolds.
Some patches of scaly skin, preserved as what Chiappe calls "a perfect replica," have patterns that resemble the adult skin of titanosaurs.
There were also near replica spatial patterns at small (<18 m) and medium (18 72 m) scales during summer and fall, possibly resulting from evapotranspiration of vegetation established in mid-summer.
To reach this end, a two-steps fabrication technique based on breath figure patterns and replica molding is here presented.
Over tea and sweets, we were regaled with snow leopard pelts, and once, the aging skin of a lion, along with pucks of hashish and firearms — often faked replicas of old British patterns offered as being torn from a dying British soldier's hands in the empire's last decades.
After a given period of time in conformal contact with the substrate, the stamp is removed leaving a replica of the stamp pattern on the substrate surface.
A short exposure to UV light caused the polymerization of the monomers in the resist, after which the mould was separated from the substrate, leaving behind an inverse replica of the mould pattern.
Since these metals can wet the native oxide on the Si, but adhere poorly, the film can be peeled off, revealing a smooth inverted replica of the original patterned template.
In addition, the model allows for the consideration of practical material handling and production features such as alternate process routings, product flow production patterns, and department replica capacities.
The results showed that most of the patterns realized by replica moulding and hot-embossing (on PDMS and polypropylene (PP), respectively) produced superhydrophobic self-cleaning surfaces.
