Their influence depends on the grain composition, size, and geometrical structure which vary throughout the dust lifecycle. Grain growth arises in dense media as traced by an enhancement of the FIR emissivity and by cloudshine and coreshine. We investigate the imprint of the grain characteristics on the dust unpolarised optical properties from the visible to the FIR for isolated grains and aggregates.
