The behaviour of free-flowing granular intruders
EPJ Web of Conferences, 2017 Particle shape affects both the quasi-static and dynamic behaviour of granular media. There has been significant research devoted to the flowability of systems of irregularly shaped particles, as well as the flow of grains around fixed intruders, however

Heterogeneous condensation for submicronic particles abatement [PDF]
, 2010 It is now well established that the emission of sub-micrometric particulate matter entrained in flue gases of industry and vehicles exhausts, is one of the most critical treats for human health because of the toxicological effects of ultrafine particles ...

How Is Indoor Air Quality during Sleep? A Review of Field Studies
Atmosphere, 2021 This review aimed to provide an overview of the characterisation of indoor air quality (IAQ) during the sleeping period, based only on real life conditions’ studies where, at least, one air pollutant was considered.

Off-axis transmission holographic system for recording aquatic particles [PDF]
, 1996 We describe a holographic system for recording particles suspended in water. The hologram plate is located in air, separated from the test tank by an air/glass/water boundary. The holographic emulsion is therefore unaffected by adverse aquatic conditions

Sublimation of ice particles from rocket exhausts in the upper atmosphere [PDF]
, 2003 The process of sublimation of ice particles from a rocket exhaust in the upper atmosphere is examined. Heating by solar radiation and losses of energy by means thermal radiation and sublimation are taken into account in the thermal balance of the ice ...
