Therefore, to avoid the generation of dusts, we propose the tightening tube mechanism.
Paramagnetic property of dusts, leads to modification of frequencies of dust lattice waves.
Indeed, the accumulation of dusts on PV panels influences the conversion efficiency of PV modules.
The authors summarized all the dust removal methods such as natural removal of dusts, mechanical removal dusts, self-cleaning nano-film and electrostatic removal of dusts (He et al. 2011).
Multiple concentrations of dusts and a stoichiometric methane mixture were tested.
Three different testing methodologies for studying the self-ignition of dusts have been undertaken.
The test methods for dust explosions have to consider a variety of kinds and forms of dusts to be tested.
