    "abstract": "We present a simulation study of the charging of a dust grain immersed in a\nplasma, considering the effect of electron emission from the grain (thermionic\neffect). It is shown that the OML theory is no longer reliable when electron\nemission becomes large: screening can no longer be treated within the\nDebye-Huckel approach and an attractive potential well forms, leading to the\npossibility of attractive forces on other grains with the same polarity. We\nsuggest to perform laboratory experiments where emitting dust grains could be\nused to create non-conventional dust crystals or macro-molecules.",
