Nonthermal Plasma Regeneration of Coke‐Deactivated Catalysts Used for Plasma‐Catalytic VOC Removal
Plasma Processes and Polymers, Volume 23, Issue 4, April 2026.The research focused on the regeneration of coke‐deactivated catalysts previously used for plasma‐catalytic toluene removal from the air. Three regeneration techniques (plasma, ozone and thermal) were compared. The plasma regeneration showed the highest efficiency in removing the coke deposits, whereas the effect of ozone and heat was negligible ...

Transonic flutter study of a wind-tunnel model of a supercritical wing with/without winglet [PDF]
The model was a 1/6.5-size, semipan version of a wing proposed for an executive-jet-transport airplane. The model was tested with a normal wingtip, a wingtip with winglet, and a normal wingtip ballasted to simulate the winglet mass properties.
