Manufacture, characterization and proton irradiation effects of 12C and 13C thick targets
(Springer, 2021-04)
Abstract: Alternative sources of neutron production other than nuclear fission reactions are important priorities in medical and nuclear applications due to costs, safety and ease of operation. In this work, 12C and 13C ...
The lifetime of a depression in the plasma density over Jicamarca produced by space shuttle exhaust in the ionosphere
(2001)
When the Space Shuttle Orbiting Maneuver Subsystem (OMS) engines bum in the ionosphere, a plasma density depression or "hole" is produced. Charge exchange between the exhaust molecules and the ambient o+-ions yields molecular ...
Exploring the interior of cuticles and compressions of fossil plants by FIB-SEM milling and image microscopy
(Wiley Blackwell Publishing, Inc, 2017-07)
We present the first study of cuticles and compressions of fossilleaves by Focused Ion Beam Scanning Electron Microscopy(FIB-SEM). Cavities preserved inside fossil leaf compressionscorresponding to substomatal chambers ...

End-to-end range prediction for heavier ion radiation therapy based on Monte Carlo simulations
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Física MédicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2020)
The presence of range uncertainties in charged particle therapy with light ions (CPT) requires the employment of safety margins during treatment planning. These affect treatment quality, not allowing to fully exploit the ...
Corrosion protection of carbon steel by silica-based hybrid coatings containing cerium salts: effect of silica nanoparticle content
(Elsevier, 2015-01-29)
One strategy for minimizing corrosive attack on carbon steel involves the application of hybrid coatings rich in rare earths, on the basis of their low toxicity and environmental sustainability. Tetraethoxysilane (TEOS) ...
