Journal article (peer-reviewed)abstract
- This paper describes the scientific aims and potentials as well as the preliminary technical design of RUDE, an innovative tool for multi-disciplinary investigations in a wide field of scientific, technological and industrial applications. IRIDE will be a high intensity "particles factory", based on a combination of high duty cycle radio-frequency superconducting electron linacs and of high energy lasers. Conceived to provide unique research possibilities for particle physics, for condensed matter physics, chemistry and material science, for structural biology and industrial applications, IRIDE will open completely new research possibilities and advance our knowledge in many branches of science and technology. [RIDE is also supposed to be realized in subsequent stages of development depending on the assigned priorities.

Conference paper (peer-reviewed)abstract
- Concerns over energy resource availability, climate change, air quality, and energy security suggest an important role for nuclear power in future energy supplies. While the current Generation II and III nuclear power plant designs provide an economically and publicly acceptable electricity supply in many markets, further advances in nuclear energy system design can broaden the opportunities for the use of nuclear energy. To explore these opportunities, worldwide governments, industries, and research centres started a wide-ranging discussion on the development of new systems known as "Generation IV." The European Commission has organized the Sustainable Nuclear Energy Technology Platform that through its Strategic Research Agenda promoted the development of fast reactors with closed fuel cycle. Among the promising reactor technologies, the Lead Fast Reactor (LFR) has been identified as a technology with great potential to meet needs for both remote sites and central power stations. The LFR system features a fast-neutron spectrum allowing the possibility for a closed fuel cycle for efficient conversion of fertile uranium and management of actinides. A full actinide recycle fuel cycle is therefore envisioned for the design of the reference LFR meant for deployment, while the capabilities of the system to act as a net-burner of actinides from spent fuel are object of further investigation The LEADER project deals with the development of such a technology through two main goals: the conceptual design of an industrial-size LFR (the so-called European LFRor ELFR) and the conceptual design of a scaled down facility, the demonstration reactor called ALFRED (Advanced Lead Fast Reactor European Demonstrator). The European Commission, withinits seventh framework programme, has approved the proposal submitted by 16 partners comprising research centres, industrial partners and universities. The project has started in April 2010 for a duration of three years.The focus of the first part of the LEADER project was the resolution of the key issues of the previous sixth framework programme ELSY project in order to reach a new consistent industrial-size reactor ELFR configuration.With reference to this reactor configuration the design of the ALFRED demonstrator (sized at 300 MWth, about 120 MWe) has been performed. The development of such demonstrator reactor presents obviously strong and interesting synergies with the development of MYRRHA, a material and fuel testing facility proposed by the SCK·CEN research centre in Belgium. In this paper we present a synthesis of the main results of the LEADER project.

Zeolite synthesis in microgravity
- 2005
-
In: Topical teams in life & physical sciences. - Noordwijk, Netherlands : ESTEC. - 929092974X ; , s. 78-85
-
Book chapter (other academic/artistic)abstract
- The results of activities performed by the members of the Topical Team on 'Zeolites synthesis in microgravity' are discussed. A method was developed using a two-temperature synthesis procedure to distinguish between the nucleation and growth phase of the crystallization. The experiments have investigated the possibility of suppressing secondary nucleation by imposing a temperature gradient. Optical thickness of the solution has been monitored by interferometry. The Team, on the basis of findings, has elaborated a research program on zeolite film deposition that includes microgravity experimentation.

Archaeological assessment reveals Earth’s early transformation through land use

Journal article (peer-reviewed)abstract
- Humans began to leave lasting impacts on Earth’s surface starting 10,000 to 8000 years ago. Through a synthetic collaboration with archaeologists around the globe, Stephens et al. compiled a comprehensive picture of the trajectory of human land use worldwide during the Holocene (see the Perspective by Roberts). Hunter-gatherers, farmers, and pastoralists transformed the face of Earth earlier and to a greater extent than has been widely appreciated, a transformation that was essentially global by 3000 years before the present.Science, this issue p. 897; see also p. 865Environmentally transformative human use of land accelerated with the emergence of agriculture, but the extent, trajectory, and implications of these early changes are not well understood. An empirical global assessment of land use from 10,000 years before the present (yr B.P.) to 1850 CE reveals a planet largely transformed by hunter-gatherers, farmers, and pastoralists by 3000 years ago, considerably earlier than the dates in the land-use reconstructions commonly used by Earth scientists. Synthesis of knowledge contributed by more than 250 archaeologists highlighted gaps in archaeological expertise and data quality, which peaked for 2000 yr B.P. and in traditionally studied and wealthier regions. Archaeological reconstruction of global land-use history illuminates the deep roots of Earth’s transformation and challenges the emerging Anthropocene paradigm that large-scale anthropogenic global environmental change is mostly a recent phenomenon.
