, 2018 Coal, gas and oil have been capitalism's main fuels since the industrial revolution. And yet, of all the fossil fuels ever consumed, more than half were burned in the last 50 years. Most alarming of all, fossil fuel consumption has grown fastest in the last three decades, since scientists confirmed that it is the main cause of potentially devastating ...

Deep borehole disposal of higher burn up spent nuclear fuels
Mineralogical Magazine, 2012 AbstractThe heat outputs of higher burn up spent fuels (SF) create problems for disposal in mined repositories, including needs for reduced container loadings and extended pre-disposal cooling. An alternative that is less temperature sensitive is deep borehole disposal (DBD) which offers safety, cost, security and other potential benefits and could be ...

Tuning Pore Size in Porous Graphene Membrane for O2/N2 Separation
Advanced Materials, EarlyView.Single‐layer graphene membranes featuring N‐functionalized, 0D pores offer a promising platform for O2/N2 separation. The heterogeneity of functional groups at the pore edge is dynamically tunable, enabling precise tuning of the pore limiting diameter and gas transport.

Asymptotic Solutions of Serial Radial Fuel Shuffling
Energies, 2015 In this paper, the mechanism of traveling wave reactors (TWRs) is investigated from the mathematical physics point of view, in which a stationary fission wave is formed by radial fuel drifting. A two dimensional cylindrically symmetric core is considered

Bounce-free spherical hydrodynamic implosion
, 2011 In a bounce-free spherical hydrodynamic implosion, the post-stagnation hot core plasma does not expand against the imploding flow. Such an implosion scheme has the advantage of improving the dwell time of the burning fuel, resulting in a higher fusion ...
