To understand market opportunities as they are evolving, the technology status of major components within current and future IGCC systems must be understood. 

The AER was developed by J.M. Huber Corporation. The process is patented and all patents are owned by the vendor. In 1984, the process was fully permitted under the Toxic Substance Control Act in Environmental Protection Agency Region VI for the destruction of PCBs (D13468I, p. 46). RIMS was unable to contact the vendor, thus the technology s current commercial status is unknown. 

The current technological status of small (0.5-5 kWe) PEM, SOFC, AFC and PAFC fuel cell stationary units, was recently reviewed by Staffed et al. (2007) (Table 3.12). The system efficiency refers to electrical losses of the fuel-cell system (fans, pumps, control) and the current conditioning unit (transformer, inverter), while total efficiency refers to both electrical power and heat cogeneration. Cost estimations refer to mass-produced fuel-cell systems according to today s state-of-the-art manufacture technologies and materials, while current retail prices of demonstration fuel-cell systems are in the range of 10,000-100,000 / kWe (Staffed et al., 2007).

It is the purpose of this paper to summarize in a necessarily brief and incomplete manner, the technological status of electric propulsion systems, and to discuss their current and future space-mission possibilities. 

Even for the intermediate-temperature SOFCs, Ni is the best anode as far as the current technological status is concerned. Although a number of investigations have been made on oxide anodes, nickel cermet (ceramic-metal) anodes exhibit... 

Status of Indirect Liquefaction Technology The only commercial indirect coal liquefaction plants for the production of transportation fuels are operated by SASOL in South Africa. Construction of the original plant was begun in 1950, and operations began in 1955. This plant employs both fixed-bed (Arge) and entrained-bed (Synthol) reactors. Two additional plants were later constructed with start-ups in 1980 and 1983. These latter plants employ dry-ash Lurgi Mark IV coal gasifiers and entrained-bed (Synthol) reactors for synthesis gas conversion. These plants currently produce 45 percent of South Africa s transportation fuel requirements, and, in addition, they produce more than 120 other products from coal.

The overproduction of a wide variety of proteins has now been achieved in . coli and other cloning hosts. Many of these proteins are in chnical trials and, as indicated earlier, over a dozen are already on the market. The current status of many of these proteins is summarized in Table 24.2. The efficacy of mai r of the proteins listed remains to be determined because until the advent of recombinant DNA technology sufficient quantities were not available to enable clinical trials to be undertaken. It should be noted that clinical efficacy alone is not sufficient. Maiket size isjust as important since it can cost up to 50 million to bring a new dmg to the market place and company shareholders expect a good return on their investment. 

Although poly(vinyl chloride) (PVC) is one of the most important commercial polymers, its outdoor use has been restricted by its photochemical instability. The reasons for this instability are incompletely understood, but some progress has been made recently on this problem, and the present paper attempts to summarize the current status of fundamental knowledge in this field. This survey is not intended to be comprehensive it is concerned primarily with work published since the early 1970 s and with basic chemical principles rather than technological developments. The photodegradation of PVC has been discussed in other recent reviews (1,2, 3 4) ...

When new technologies are not available to all members of a society, they can exacerbate existing inequalities in the system of medical care. Currently the structure of the U.S. health care system is fundamentally flawed. Racial and ethnic disparities in health status and health care, more than 40 million uninsured, spiraling health care costs, and inadequate levels of culturally competent medical care are all evidence of this problem.
