This manuscript describes the elaboration of temperature sensitive highly magnetic latex particles. The particle core is crosslinked polymer matrix containing iron oxide nanoparticles. The shell is a combination of highly crosslinked hydrophobic polymer and crosslinked stimuli responsive hydrophilic polymer. The polymerization was performed in two steps: the elaboration of seed magnetic latex particles for oil in water magnetic emulsion and (ii) the functionalization of the obtained magnetic latexes via seed polymerization in the presence of water soluble reactants. The obtained final core-shell latexes exhibit the following properties: The iron oxide content is above 50 wt.%. The size distribution is governed by the size distribution of the used oil in water magnetic emulsion. The thermal sensitivity of the shell is due to the presence of poly(N-isopropylacrylamide). The cationic character of the outer layer shell is due to the use of cationic initiator and amino containing monomer.

Confined explosions represent a serious safety hazard as significant damage to humans and structures is observed, unlike in free-field explosions. An experimental small-scale study investigated the blast wave in a single-story building. The blast waves were generated by the detonation of a gaseous charge. The building was divided into two rooms by a movable wall which could be positioned at three different locations. The presence of an opening in this movable wall means that two rooms were considered: a transmitter room (TR) and a receptor room (RR). The configuration without the movable wall was also studied. Pressure profiles recorded with pressure gauges at ground level and on the wall presented numerous reflections. The damage effects were severe since the maximum overpressure never fell below 0.2 bar. Although this study is limited to a small scale and gaseous detonation charge, the results can be applied to a large scale and for a TNT charge.
