Protonic conductivity and thermal properties of cross-linked PVA/TiO2 nanocomposite polymer membranes
(2019-10-15)
Nanocomposite polymer membranes based on PVA/TiO2 were prepared by a solution casting method. Glutaraldehyde solution (GA) was used as linking agent to improve the chemical, thermal and physical properties of the membranes. ...
Application of 137Cs and 210Pb radionuclides to determine sedimentation rates of recent sediments from admiraty Bay, Antarctica Peninsula
(Associação Brasileira de Energia NuclearRio de Janeiro, 2009-09-27)
Studies about natural and artificial radionuclides in areas such as the Antarctic are key to understand natural and
dynamic processes in marine environments. These studies are important to determine levels of radioactiv ...
Further investigating the determination of phosphorus in plants by INAA using bremsstrahlung measurement
(SPRINGERDORDRECHT, 2012)
Phosphorus is an essential element for plants and animals, playing a fundamental role in the production of biochemical energy. Despite its relevance, phosphorus is not commonly determined by instrumental neutron activation ...
Electron detachment cross sections of CH4 - colliding with O2 and N2 below 10 keV energies
(2014)
Negative methane is an interesting molecular anion from a fundamental point of view and also because it can be a source of thermal electrons in low temperature hydrocarbon plasma. Measurements of collisional electron ...
