Nanotechnology: radical new science or plus ça change? (2005)
Journal Article
Moriarty, P. (2005). Nanotechnology: radical new science or plus ça change?. Nanotechnology Perceptions, 1,

Is a radical nanotechnology involving the construction of macroscopic products via software-directed manipulation of single molecules possible? Are we only a few decades away from a technological utopia where virtually any product may be constructed... Read More about Nanotechnology: radical new science or plus ça change?.

The Lyman-alpha forest opacity and the metagalactic hydrogen ionization rate at z~2-4 (2005)
Journal Article
S. Bolton, J., G. Haehnelt, M., Viel, M., & Springel, V. (2005). The Lyman-alpha forest opacity and the metagalactic hydrogen ionization rate at z~2-4. Monthly Notices of the Royal Astronomical Society, 357(4), 1178–1188. https://doi.org/10.1111/j.1365-2966.2005.08704.x

Estimates of the metagalactic hydrogen ionization rate from the Lyman-alpha forest opacity in QSO absorption spectra depend on the complex density distribution of neutral hydrogen along the line-of-sight. We use a large suite of high resolution hydro... Read More about The Lyman-alpha forest opacity and the metagalactic hydrogen ionization rate at z~2-4.
