Future trends continuous improvement

Diamond s properties make it the desirable material in thermal, optical, electrical, electronics, and mechanical applications. It has not been exploited to its maximum potential. Future trends are toward applications in medicine, biology, and the nuclear field. These fields already have applications that use diamond but continuous improvements are being made through research. Diamond is a strong candidate as a substitute for materials currently being used in a variety of applications. Although implementation may be deterred by cost factors or technical issues, the development of new deposition techniques may overcome this limitation. Deposition techniques and a higher control of processes surely will help to launch more sophisticated electronic applications that eventually will realize diamond s superior performance over other materials. 

Comparison of the compounds in Schedules 1 and 2 with the general structure-activity trends discussed in Section XII shows that most of the highly toxic compounds and their analogues are included. The hope is that this Convention, supported by the availability of continually improving verification and defensive measures, will in the future prevent any production or use of CW agents. 

Over the years, improvements in aromatic alkylation technology have come in the form of both improved catalysts and improved processes. This trend is expected to continue into the future. 

Continuing the current trend, there will be an even greater need to provide highly effective dispersants with minimum environmental impact. Future development efforts will focus on improved performance at low dosage to further reduce the environmental load, accountability (ability to detect... 

The synthesis of PS chiral analogues of biophosphates via P compounds required as therapeutic continues to attract attention. It is apparent that future perspectives in this fascinating area will focus on finding easy access to chiral P compounds other than the separation of diastereoisomers and improvements in the stereoselective coupling procedures. So far research efforts in synthesis of new drugs with a phosphorus backbone has paid insufficient attention to cost and difficulties of large scale production [110]. This chapter illustrated the trends with a series of selected examples. 

Over a period of about twenty years the results of surveillance for veterinary drug residues in meat and animal products in the UK have provided reassurance that residues of veterinary drugs occur at very low concentrations and generally at low frequencies. Over this period repeated surveillance and improved communication and awareness of the producer and feed industry has resulted in a downward trend in the level and incidence of residues detected. However, contamination hot spots remain (e.g. animal medicated feed) and will continue to be monitored in the future. In addition, as new products are introduced into the market they will be evaluated during the licensing process to establish any risk from their residues present in human food. The UK also imports a significant amount of animal-derived food and the presence and risk to the UK consumer of residues in these products must also be considered and appropriate measures taken to protect the UK consumer.
