Supercritical fluid extraction and temperature-programmed desorption of phenol and its oxidative coupling products from activated carbon
HUMAYUN, RASHINA; Karakaş, Gürkan; Dahlstrom, PR; OZKAN, UMIT S; TOMASKO, DAVID L (1998-08-01)
Activated carbon remains one of the most economical adsorbents for the removal of contaminants from water. In particular, activated carbon is known to have an extremely high affinity for phenol and its derivatives. This has been shown to be the result of a catalytic process wherein activated carbon catalyzes the oxidative coupling reactions of phenol in aqueous solution when molecular oxygen is present. These reactions are believed to be the source, of the difficulty of regenerating activated carbon loaded ...
Superelasticity and compression behavior of porous TiNi alloys produced using Mg spacers
Aydoğmuş, Tarık; Bor, Sakir (2012-11-01)
In the scope of the present study, Ni-rich TiNi (Ti-50.6 at %Ni) foams with porosities in the range 38-59% were produced by space holder technique using spherical magnesium powders as space formers. Single phase porous TiNi alloys produced with spherical pores were subjected to loading-unloading cycles in compression up to 250 MPa stress levels at different temperatures in as-processed and aged conditions. It has been observed that strength, elastic modulus and critical stress for inducing martensite decrea...
Free surface flow past a circular cylinder under forced rotary oscillations
Kocabıyık, Serpıl; Bozkaya, Canan; Liverman, E. (null; 2014-07-25)
Numerical results of a viscous incompressible two-fluid model with an oscillating cylinder are analyzed. Specifically, two-dimensional flow past a circular cylinder subject to forced rotational oscillations beneath a free surface is considered. Numerical method is based on the finite volume method for solving the two-dimensional continuity and unsteady NavierStokes equations. The numerical simulations are carried out at a Reynolds number of R = 200 and a Froude number F r = 0.2, and the cylinder submergence...
