Lighting future trends

Light olefins, particularly tertiary olefins, are very reactive in forming ozone and also increase gasoline pool RVP. However, the future trend of most FCC operations is projected to produce more olefin feed, but little will reach the gasoline pool. This is because olefins, particularly the C4 and Cg olefins, can either be alkylated and/or etherified, or used for petrochemical feedstock. 

In Section 2.2.5 the general trends in plastic pipe supply over a long period of growth from the late 1960s, were discussed. No attempt was made to analyse the nature of demand that was generating the market. In the light of the discussion of market sectors, how the applications sectors have determined the materials and products that were successful will now be considered with the intention of perceiving the future trends.

The relevance of photonics technology is best measured by its omnipresence. Semiconductor lasers, for example, are found in compact disk players, CD-ROM drives, and bar code scaimers, as well as in data communication systems such as telephone systems. Compound semiconductor-based LEDs utilized in multicolor displays, automobile indicators, and most recendy in traffic lights represent an even bigger market, with approximately 1 biUion in aimual sales. The trend to faster and smaller systems with lower power requirements and lower loss has led toward the development of optical communication and computing systems and thus rapid technological advancement in photonics systems is expected for the future. In this section, compound semiconductor photonics technology is reviewed with a focus on three primary photonic devices LEDs, laser diodes, and detectors. Overviews of other important compound semiconductor-based photonic devices can be found in References 75—78. 

The disadvantage of this procedure is that it doubles the amount of time required to acquire a data set, doubles the size of the data set, and exposes the sample to twice as much excitation light. More recently, an approach has been described in which phase step acquisition is randomized so that there is no trend in photobleach-ing or related elfects in the analysis [29], This approach is relatively new, is reported to work very well, and should see more widespread use in the future. 

In light of the current developments in the field of phosphaalkyne chemistry, the authors of the present chapter are hopeful and optimistic that this trend will continue in the future.
