In this article, we report the successful preparation of a Mg-based luminescent MIL-53 metal–organic framework (MOF), namely [Mg2(BDC)2(BPNO)]·2DMF (1) (BDC = 1,4-benzene dicarboxylate, BPNO = 4,4’- dipyridyl-N,N’-dioxide, DMF = N,N-dimethylformamide) in a mixed solvent containing a 2 : 3 volume ratio of DMF and ethanol (EtOH) under solvothermal conditions. Desolvated compound 1a can be used as an absorbent for selective adsorption and separation of liquid explosives, including nitroaromatic (nitrobenzene (NB)) and nitroaliphatic (nitromethane (NM) and nitroethane (NE)) compounds, through single crystal-to-single crystal (SC–SC) transformations. As one of the weakly luminescent MOFs, the luminescence of compound 1a could be quenched by …

Six chemical engineering undergraduates at the University of South Carolina formed a team to compete in the 2014 AIChE Chem-E-Car competition at the Southern Regional Student Conference in San Juan, Puerto Rico, in March. In the Chem-E-Car competition, students must design and build a vehicle powered by an unconventional form of chemical energy to carry a specified weight over a given distance (1). The group used knowledge gained through undergraduate study to construct a small-scale vehicle that is powered by a set of thermoelectric generators utilizing a heat gradient between boiling water and an ethanol-dry ice mixture (2). An iodine …
