The effect of turbulent clustering on particle reactivity

open access: yes, 2016
The effect of turbulence on the heterogeneous (solid-fluid) reactions of solid particles is studied numerically with Direct Numerical Simulations (DNS).

On the Ionisation Fraction in Protoplanetary Disks II: The Effect of Turbulent Mixing on Gas--phase Chemistry [PDF]

open access: yes, 2005
We calculate the ionisation fraction in protostellar disk models using two different gas-phase chemical networks, and examine the effect of turbulent mixing by modelling the diffusion of chemical species vertically through the disk.

Stress relaxation of narrow molar mass distribution polystyrene following uniaxial extension [PDF]

open access: yesJournal of Rheology, 2008
The stress in the startup of uniaxial elongational flow until steady state, followed by stress relaxation, has been measured for a narrow molar mass distribution polystyrene melt with a molecular weight of 145kg∕mol. The experiments are conducted on a filament stretching rheometer, where a closed loop control of the midfilament diameter ensures ...

Bayesian semiparametric inference for multivariate doubly-interval-censored data [PDF]

open access: yes, 2010
Based on a data set obtained in a dental longitudinal study, conducted in Flanders (Belgium), the joint time to caries distribution of permanent first molars was modeled as a function of covariates.

Preparation of gelatin beads treated with glucose and glycerol

open access: yesPolímeros
Gelatin is employed in pharmaceutical applications because of its biodegradability, biocompatibility and low toxicity. However, it may be necessary to promote gelatin crosslinking in order to develop drug release systems and extend release times.

Sensitivities of the absorptive partitioning model of secondary organic aerosol formation to the inclusion of water [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
The predicted distribution of semi-volatile organic components between the gaseous and condensed phase as a function of ambient relative humidity and the specific form of the partitioning model used has been investigated.

Experimental study of the effects of hypochlorite on polysulfone membrane properties [PDF]

open access: yes, 2006
Although chemical solutions are widely employed to clean membranes, they can also be responsible for changes in membrane properties. The two major drawbacks are then either the functional properties of the membrane gradually change, so the production can

Molar-mass distribution of urea–formaldehyde resins of different degrees of polymerisation by MALDI-TOF mass spectrometry [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
This paper describes some results obtained in an investigation of urea–formaldehyde (UF) resins of different degrees of polymerisation by matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF) mass spectrometry (MS).
