Shandilya, N. (author), Le Bihan, O. (author), Bressot, C. (author), Morgeneyer, M. (author)The present article presents an experimental protocol to investigate particle aerosolization of a product under abrasion and under environmental weathering, which is a fundamental element to the approach of nanosafety-by-design of nanostructured products for their durable development. This approach is basically a preemptive one in which the...article 2016

de Cazenove, T. (author), Bouma, R.H.B. (author), Goetheer, E.L.V. (author), van Os, P.J. (author), Hamborg, E.S. (author)There are two main routes for amine emission. The first one is connected to volatile amine emission. The second route is amine emission via aerosols. Recently, it has been observed that under certain conditions and at specific test locations significant aerosol formation and emission can occur. To distinguish between the two routes for amine...conference paper 2016

Shandilya, N. (author), Morgeneyer, M. (author), Le Bihan, O. (author)In this work, the particle aerosols emissions during the abrasion of three products – brick, wood and stainless steel – are measured. Owing to different material removal mechanisms in these three products during their abrasions, different quantities and generation rates of aerosols are observed with the brick producing the highest number at a...article 2015

However, results are dependent on the specific methods used. In order to have well-characterized aerosols, we require a better understanding of how system parameters and testing conditions influence...article 2015

Donovan, D.P. (author), Klein Baltink, H. (author), Henzing, J.S. (author), de Roode, S.R. (author), Siebesma, A.P. (author)The fact that polarisation lidars measure a depolarisation signal in liquid clouds due to the occurrence of multiple scattering is well known. The degree of measured depolarisation depends on the lidar characteristics (e.g. wavelength and receiver field of view) as well as the cloud macrophysical (e.g. cloud-base altitude) and microphysical (e.g...article 2015
