TL;DR: In this paper, the authors present and likely future bottlenecks analysis for a sustainable photovoltaic policy, carried out by Bayer and Life, within EPIA, sponsored by the European Commission, within the ALTENER programme, shows that the feedstock used to date, based on electronic grade silicon Scraps is already limiting the PV market expansion even if a true shortage is not expected before 2004-2005 according to a low growing PV market scenario.

TL;DR: The economic importance of nuclear energy availability of uranium and thorium nuclear reactor types nuclear fuel production disposal of waste from nuclear power stations is discussed in detail in this article, where the authors present an economic analysis of the nuclear fuel cycle.

TL;DR: The nuclear fuel cycle is the series of industrial processes which involve the production of electricity from uranium in nuclear power reactors as discussed by the authors, which is a relatively common element that is found throughout the world and must be processed before it can be used as fuel for a nuclear reactor.

TL;DR: In this article, a liquid semi-conductor is solidified on a horizontal support and a molding body is placed on the horizontal support to support the liquid semiconductor.

TL;DR: An acicular, magnetic iron oxide pigment containing about 0.1 to 2 percent by weight of zinc and phosphate ions is produced by growing seeds and subsequently reducing and optionally reoxidizing acicular FeOOH as discussed by the authors.
