An area of recent interest for printed electronics is printed sensors. The general concept is to develop simple sensors for product quality monitoring, etc., that use small numbers of transistors with very low performance. This is a diffuse area that is still developing, and therefore will not be discussed here. However, it is important to note that many of the concerns that apply to displays and RFID apply here as well, and therefore, the main technology driver for most areas of printed electronics continues to be the printed transistor. 

Pleural plaques Localized or diffuse areas of thickening of the pleura (lining of the lungs or chest cavity. Pleural plaques are detected by chest x-ray, and appear as opaque, shiny, and rounded lesions. 

Multiply bonded phosphorus compounds are often reactive as heterodienophiles. However, diis is a diffuse area of research and little systematic study of these Diels-Alder reactions has been done. A complete listing of the various types of phosphorus dienophiles is beyond the scope of diis review. Some of this material is available in previous summaries. Selected representative examples of recent activity in this area is given in equations (109), (110), (111) and (112). ... 

The percent recovery, which is determined as (Y/X) X 100 = % recovery. It gives the mobile fraction of the probe. If the radius of the illuminated area is small compared with the diffusion area (cell, vesicle, etc.) and the molecules are free to diffuse, then the percent recovery must be 100%. On the other hand, if the fluorescence fails to recover to the same intensity observed before the bleaching pulse, then it indicates that a fraction of fluorophores exist, which are immobile on the time scale of the experiment Dj < 10 cm /s).

Calluses are more diffuse areas of thickening on the sole or the side of the foot. 

In the intermediate region a transient lineshape emerges whose position is 1-2 order larger than the mesh size. This area is sometimes called a transient anomalous diffusion area [18]. The position of the transient is shifted to smaller I (or Tots) on increase in the HA concentration, that is, decrease in mesh size. 

These values are consistent with our previous results concerning anomalous diffusion in HA solution in which the location of the transient anomalous diffusion area is 10-100 nm. The existence of HA never disturbs a reaction space smaller than the 10-100 nm scale where the observed value of D is unchanged from the value without HA (D0). If the signaling molecules are provided within this small volume, in... 

The study of macrokinetics of reaction VOCI3 with silica gel has shown also, that the process proceeds in outside diffusion area. The significant intensification of interaction is observed during the synthesis in the fluidized regime of solid phase [10,45]. 

Two problems are regularly encountered by those investigating coordination polymer structures - evaluation of diffuse areas of highly disordered guest mole-... 

LOSS of EvOH BARRIER PROPERTIES DURING RETORT Oxygen permeation measurements were made using a modified MOCON Ox-Tran 100 permeation cell which is a commercially available instrument. The experimental procedure has been described previously (24). Film samples were fixed in a machined brass block with a diffusion area of 50 cm. ... 

As was observed for the C500 silica, reanalysis of the pore structure by nitrogen sorption (Figure 8, curve c) following intrusion and removal of mercury indicates that the porosimetry experiment results in a permanent loss in pore volume and a shift to smaller pore sizes. In C200, however, this loss in pore volume no longer approximates that associated with the broad-diffuse area of the intrusion trace. Instead, the loss represents only...
