We characterized the on-board megavoltage imager (MVI) of a magnetic resonance-guided radiotherapy machine for beam output checks. Linearity and repeatability of its dose response were investigated. Alignment relative to the beam under clinical circu

Beam output checks of a commercial high-field magnetic resonance-guided radiotherapy machine can be performed with its on-board megavoltage imager (MVI). This is a fast and efficient method, but only recommended for daily checks. The aim of our study

Evidence for adsorption assisted desorption of 13NH3 in the presence of gas phase ammonia on γ-alumina is presented. Due to lateral interactions with physisorbed ammonia, the adsorption enthalpy of ammonia on γ-alumina was measured to be −11 ± 1

The influence of the loading on the self-diffusion of 3-methylpentane within silicalite-1 has been studied with Positron Emission Profiling technique. A monotonous decrease in the self-diffusivities of alkane was observed with zeolite loading, which

The hydroisomerization of hexane on platinum-loaded acidic zeolites was studied with positron emission profiling (PEP), a tracer imaging technique based on the same principle as positron emission tomography. The unique character of PEP enables the de

Molecular dynamics simulations are used to study the self- diffusion of linear and branched alkanes in the zeolites Mordenite, ZSM-5, Ferrierite, and ZSM-22. A rigid zeolite model and a united atom model for the alkanes was used in these simulations.

Using 1D- and 2D-exchange 13C NMR techniques it is shown that n-pentane translation in zeolite ZK-5 occurs by hopping between neighboring and cages. Owing to the structure of the ZK-5 pore network, these techniques give direct information about the t

The ability of positron emission profiling (PEP) to measure concentration profiles of molecules labelled with positron-emitting nuclei, such as 11C, 13N, and 15O, inside chemical reactors has been demonstrated for the system n-hexane–Pt/H-zeolites
