Stacked layered approach

In order to compete with the high efficiencies of cells fabricated using physical vapor deposition [7], it is necessary to optimize the bandgap of the materials by incorporating Ga with a controlled concentration profile. Ga incorporation in ED films was first achieved by Calixto el al. in a co-deposition of aU elements [79], The best electrochemically incorporated Gadevice efficiency of over 10% by using a stacked layered approach. [Pg.19]

In contrast to the flow-directed and Langmuir-Blodgett approaches described above, the printing approach used to deposit the NWs is a dry stamping approach analogous to that described in Chapter 13. Up to 10 addressable vertically stacked layers have been demonstrated. Each layer... [Pg.370]

A further example of a bionanotechno-logical approach in tissue design is the development of sheets of myocardial cells without a scaffold [55]. Electrical communication as an essential parameter of myocardial cells was established between different layers and proved by autonomously contractions of the stacked layers (see also... [Pg.1547]

Several IC chips are assembled using MCM techniques and the layers are stacked similarly to package stacking. Layer-to-layer interconnects are produced using an interposer such as fuzz button layers that differentiate this approach from the... [Pg.254]

These fabrics are well suited for use in closed molding applications. They allow reduction in both the kit cutting time and the part loading time, by combining all layers of a laminate into one stack. As the marine industry is moving into closed molding, it needs to rethink the laminate composition and move away from a layer-by-layer approach. [Pg.101]

As already mentioned, the fiber system of GDLs is modeled by a multi-layer approach, that is, a stack of thin sections, where the fibers are modeled by planar Poisson line systems within each section. [Pg.671]

In this work, a trust-based approach was proposed to ensure intrusion tolerant routing in WSNs. For this purpose, an additional layer was introduced in the WSN protocol stack such layer performs intrusion tolerance activities and masks information to routing layer when more dependable information are estimated to be already available. The layered approach proposed allows us to provide tolerance capabilities to existing protocols. This cannot be ensured when instead... [Pg.227]

There are many more subtle intermediate features that have also been observed. In addition to the endothermic behavior of the isotropic melt, calorimetric measurements [110] detect a second endothermic peak at somewhat lower temperatures. This new feature corresponds to (on heating) a transition to a liquid crystalline (LC) phase wherein the individual stacked layers become decoupled from one another and are essentially free-floating. The main-chain planarity is only somewhat affected by this transition, while the alkyl-containing side groups show a significant increase in the relative proportion gauche conformers as the transition is approached from a lower temperature. [Pg.720]

Consequently, Bakker (1996) described the concentration evolution of a single layer subjected to the vorticity field of a single CSV by means of a onedimensional differential equation where both the nondimensional time and the nondimensional spatial coordinate contain the exponential shrinking rate. In this respect, the CSV approach differs from the various Bourne models in which the successive generation of several multiple-layer stacks is required and vortex age is a crucial element. [Pg.211]

In the vapor-deposited OLED community, a number of approaches have been employed to produce white light emission. White OLEDs have been demonstrated based on multilayer structures, e.g., stacked backlights [153,168], multidoping of single-layer structures [145], phosphorescent monomer-excimer emission layers [169] and on doping of phosphorescent materials into separate bands within the emission zone, called a tri-junction [170]. The trijunction device has produced the highest white OLED efficiency of 16% external quantum efficiency demonstrated thus far [171]. [Pg.556]

Mitsubishi Electric Corporation investigated alloyed catalysts, processes to produce thinner electrolytes, and increases in utilization of the catalyst layer (20). These improvements resulted in an initial atmospheric performance of 0.65 mV at 300 mA/cm or 0.195 W/cm, which is higher than the IFC performance mentioned above (presented in Table 5-2 for comparison). Note that this performance was obtained on small 100 cm cells and may not yet have been demonstrated with full-scale cells in stacks. Approaches to increase life are to use series fuel gas flow in the stack to alleviate corrosion, provide well-balanced micro-pore size reservoirs to avoid electrolyte flooding, and use a high corrosion resistant carbon support for the cathode catalyst. These improvements have resulted in the lowest PAFC degradation rate publicly acknowledged, 2 mV/1000 hours for 10,000 hours at 200 to 250 mA/cm in a short stack with 3600 cm area cells. [Pg.114]
