Regeneration of three-way automobile catalysts using biodegradable metal chelating agent-S, S-ethylenediamine disuccinic acid (S, S-EDDS)
Subramanian, B.; Christou, Stavroula Y.; Efstathiou, Angelos M.; Namboodiri, V.; Dionysiou, Dionysios Demetriou D. (2011)Regeneration of the activity of three-way catalytic converters (TWCs) was tested for the first time using a biodegradable metal chelating agent (S, S-ethylenediamine disuccinic acid (S, S-EDDS). The efficiency of this novel ...

Time-dependent compressible extrudate-swell problem with slip at the wall
Georgiou, Georgios C. (1994)We solve the time-dependent compressible Newtonian extrudate-swell problem with slip at the wall, in an attempt to simulate the stick-slip extrusion instability. An arbitrary nonlinear slip model relating the shear stress ...
