Study of an ADS Loaded with Thorium and Reprocessed Fuel
Science and Technology of Nuclear Installations, Volume 2012, Issue 1, 2012., 2012 Accelerator‐driven systems (ADSs) are investigated for long‐lived fission product transmutation and fuel regeneration. The aim of this paper is to investigate the nuclear fuel evolution and the neutronic parameters of a lead‐cooled accelerator‐driven system used for fuel breeding. The fuel used in some fuel rods was 232ThO2 for 233U production.

Deuterium retention in tin (Sn) and lithium–tin (Li–Sn) samples exposed to ISTTOK plasmas
Nuclear Materials and Energy, 2017 The use of lithium (Li) or tin (Sn) as a liquid metal plasma facing component is proposed as a solution to the high power load issue on the divertor region of nuclear fusion reactors.

Amplification and generation of ultra-intense twisted laser pulses via stimulated Raman scattering
Nature Communications, 2016 High intensity light with a non-zero orbital angular momentum could aid the development of laser-wakefield particle accelerators. Here, the authors theoretically show that stimulated Raman backscattering in plasmas can generate and amplify orbital ...

Cinema e televisão: uma fusão desigual [PDF]
, 2016 Entre a Televisão e o Cinema… as relações são complexas e desiguais. A TV tem sido sempre considerada o «parente pobre». Porque é um media de massas dirigido a audiências muito vastas e indiferenciadas; porque parece gratuita… é da ordem da Aparição ...

Laser-wakefield accelerators as hard x-ray sources for 3D medical imaging of human bone [PDF]
, 2015 A bright μm-sized source of hard synchrotron x-rays (critical energy Ecrit > 30 keV) based on the betatron oscillations of laser wakefield accelerated electrons has been developed.

Plasma Processes and Polymers, Volume 22, Issue 7, July 2025.Energy cascades through the degrees of freedom of CO 2 like through a set of funnels. The funnel of symmetric stretching and bending is so wide that it is no obstacle to the energy. Exciting the system with single pulses prevents most energy from being deployed in chemical reactions.
