If a double-layer hollow area of the fabric is surrounded by a joint weave, the borderline between the two could be regarded as a woven seam. Unfolding of this hollow area can be done, for example, by inflating, and this may require a certain level of seam strength. The details of weave design have a significant influence on the strength of woven seams. 

Preparing polymer nanocomposite OLED devices containing semiconductor NCs still remains a challenge. However, a few EL devices have been fabricated successfully [30-38]. For instance, Liu et al. investigated the properties of diode structures fabricated from PVK conducting polymer and luminescent Au-CdSe/ZnS core-shell nanocrystals. A series of double-layered EL devices with structures as represented in Fig. 3 were designed and fabricated [30]. 

Quadraxially oriented (four directional layer) glass fabric-TS vinyl ester polyester RP sheet panels with a foam core and gel coating are used. Most of the panels are 3 mm thick with molded-in rib structure supports. Body skins are bonded to the chassis with a double-stick acrylic tape developed by 3M Co. as well as mechanical fasteners. Unlike most steel designs, no B-pillar structural component between the front and rear doors is required thus providing more interior space and easy entry since doors open in opposite directions. 

The Premere PFO occluder (Fig. 7) is another selfexpanding double disc device specifically designed for PFO closure. The right-sided anchor is constructed of nitinol between two layers of knitted polyester fabric connected by a flexible polyester braided tether to the left atrial anchor. The left atrial anchor consists of four radiating arms without polyester layers to improve tissue absorption and to minimize thrombus formation. Since the distance between the anchors...
