There is an overview of the probe nanotechnology research in the Center of Probe Microscopy and Nanotechnology of MET (TU). We demonstrate the results in development of quasi-one-dimensional metallic and carbon electronics, carbon nanotubes production, sensor application, and graphene based nanosystem devices. 

A very interesting task would be automatic measurement of the product and the calculation of production rates. This would allow automatic optimization of the process by a computer program that varies all relevant parameters, probably by multiparameter analysis, to find the best production conditions. As long as there are no product sensors available, the main problem may be the time necessary for the measurement of an automatically taken sample. However, the use of HPLC methods can give accurate results within 20 min, and high-performance capillary electrophoresis (HPCE), with an analysis time of 5 min, could be introduced (Beckman PIACE 2(X)0, E. Wasserbauer, personal communication and James et al, 1994). Nonetheless, further development is necessary before these methods can be used routinely for automatic fermentation analysis.

The last chapter in this text deals with sensor commercialization and markets. Chemical and biosensors are following a commercialization pathway similar to other detection and measurement devices such as analytical chemistry instrumentation in the 1950s and 1960s, and immunoassay in the 1970s and 1980s. Common to these products, sensors will achieve a critical mass which will push them into large-scale commercialization by the first part of the 21st century. 

These types of sensors are represented by semiconductor devices and devices incorporating solid electrolytes. These have certain advantages over sensors utilising liquid electrolytes. These are the inherent, robust nature of such sensors, the lack of problems due to evaporation of solvent or corrosion due to spillage, the possibilities of miniturisation and the possibility of mass production. Sensors based on solid electrolytes usually operate in the potentiometric or amperometric mode but the semiconductor devices usually operate by measuring changes in conductivity.

Sensors on the tree allow the control module to transmit data such as tubing head pressure, tubing head temperature, annulus pressure and production choke setting. Data from the downhole gauge is also received by the control module. With current subsea systems more and more data is being recorded and transmitted to the host facility. This allows operations staff to continuously monitor the performance of the subsea system. 

Safety has been greatly increased by use of the continuous nitration processes. The quantity of nitroglycerin in process at any one time is greatly reduced, and emulsification of nitroglycerin with water decreases the likelihood of detonation. Process sensors (qv) and automatic controls minimize the likelihood of mnaway reactions. Detonation traps may be used to decrease the likelihood of propagation of an accidental initiation eg, a tank of water into which the nitrated product flows and settles on the bottom. 

Throughout the history of the development of fats and oils, many wet chemical methods have been developed to assess the quaUty of the raw materials and products. As sophisticated instmmentation develops, many of the wet methods are being replaced. Particular attention is being given to methods that eliminate the use of solvents which cause an environmental disposal problem. Many in-line sensors are also being developed to allow corrections of critical parameters to be made more quickly in the process. 

The minienvironment approach to contamination control has been increasing in use. A minienvironment is a localized environment created by an enclosure that isolates the product wafer from contamination and people (48). Another approach is using integrated processing, where consecutive processes are linked in a controlled environment (32). Both requite in situ sensors (qv) to measure internal chamber temperatures, background contamination, gas flow rates, pressure changes, and particularly wafer temperature (4). 

The signal is reflected from the product surface because there is an abmpt impedance change in the sensor at the air—product interface. Because the electromagnetic field extends outside the two sensor conductors, the sensor impedance depends on the dielectric constant of the surrounding medium. In...
