A series of molecular dynamics (MD) simulations of different pregelification mixtures representing intermediate stages of the sol-gel process were set up to gain insight into the molecular imprinting process in xerogels, namely, to assess the template-gel affinity and template self-aggregation. The physical plausibility of the parametrization was checked,(More)
Macromolecules, such as polyethylene glycol (PEG), have been frequently used in the preparation of xerogels, mainly with the purpose of tuning the meso- or macroporosity. However, PEG has never been applied in the context of the preparation of molecularly imprinted xerogels for small molecules. Thus, we decided to conduct a computational and experimental(More)
9 Active target detection systems, where the gas used as the detection medium 10 is also a target for nuclear reactions, have been used for a wide variety of 11 nuclear physics applications since the eighties. Improvements in MPGD (Mi12 cro Pattern Gaseous Detectors) and in micro-electronics achieved in the last 13 decade permit the development of a new(More)
Sol-gel molecularly imprinted materials (MIMs) are traditionally obtained by grinding and sieving of a monolith formed by bulk polymerization. However, this process has several drawbacks that can be overcome if these materials are synthesized directly in the spherical format. This work aimed at the development of two efficient methods to prepare spherical(More)
Total fission cross section induced by protons in <sup>181</sup>Ta and <sup>208</sup>Pb at energies in the range of 300 to 1000 A MeV have been measured at GSI (Germany) using the inverse kinematics technique. A dedicated setup with high efficiency made it possible to determine these cross sections with high accuracy. The new data seed light in the(More)
