Quiz Questions

1.Nanotechnology is often termed a system innovation, implying that it is expected to initiate an increasing number of innovative developments in various sectors of technology, various social areas of applications and economic sectors.
True
False
2.

The core elements of technology assessment are illustrated in __________________________.

Figure 1
Figure 2
3.The relatively big specific surface of nano-particles usually leads to an increase in their chemical reactivity and catalytic activity. The relatively small amount of atoms within nano-particles offsets the quasi-continuous solid state of the particle, leading to new, deviating, optical, electrical and magnetic features.
True
False
4.The evaluating nano technological production methods are discussed in _____________________.
Table 1
Table 2
5.The arrows (figure 2) between the individual steps highlight the interactive nature of the procedure, with the outcome of a given step always being fed back into the preceding stage and resulting, if necessary, in the repetition of the procedure.
True
False
6.

The advantages of using nano-varnishes are visible in VOC-emissions, specifically in the life-cycle stages of varnish production. The VOC-emissions of the nano-varnish are thus 65 per cent lower than the emissions of other varnishes.

True
False
7. Acidification is caused by nitrogen oxide, sulphur oxide, ammonia, hydrochloric acid and fluoro carbon emissions.
True
False
8.Technology shaping is only to a limited extent controllable through political intervention. Technology is the result of tangible cooperative action of very different actors leading to the development of a technology path which can be shaped at the same time it evolves.
True
False
9.

The window of opportunity for technology shaping throughout the life cycle is illustrated in _______.

Figure 3
Figure 4
10.A technology path is not only shaped by science but also by investment and already established knowledge. Guiding principles should shape these activities in their entity. Guiding principles can thus shape the direction of responsible technological development and con-tribute to a safe path of development.
True
False
