The influence of manganese-cobalt oxide/graphene on reducing fire hazards of poly(butylene terephthalate)
MnCo2O4–GNS hybrids Nanocomposites Thermal hazards Smoke hazards Poly butylene terephthalate
2015/3/24
By means of direct nucleation and growth on the surface of graphene and element doping of cobalt oxide(Co3O4) nano-particles, manganese–cobalt oxide/graphene hybrids (MnCo2O4–GNS) were synthesized tor...

2009/10/23
The kinetics of phase transformations of the austenite of 6Mn16 steel during continuous cooling are presented in a CCT diagram. Manganese partitioning between ferrite and austenite during intercritica...
Manganese oxide nanoparticle-assisted laser desorption/ionization mass spectrometry for medical applications
metal oxide transmission electron microscopy ionization
2010/1/19
We prepared and characterized manganese oxide magnetic nanoparticles (d =5.6 nm) and developed nanoparticle-assited laser desorption/ionization (nano-PALDI) mass spectrometry. The nanoparticles had Mn...
Cracks in high-manganese cast steel
Hadfield cast steel Hot cracking Solidification brittleness
2011/4/1
The reasons which account for the formation of in service cracks in castings made from Hadfield steel were discussed. To explain the source of existence of the nuclei of brittle fractures, the proper...
