Description:Literature Seminar:\n\nPetroleum derivatives have long served i
 n the production of fuels\, materials\, and energy. As a fuel source\, the
 se derivatives have found to be resourceful in the transportation sector f
 or many decades with respect to flight and on-ground travel. However\, the
  combustion of these fuels leads to the production of gases and particulat
 e matter known to contribute to global warming and have adverse human heal
 th effects. To mitigate this\, many commercial ground vehicles come equipp
 ed with catalysts capable of oxidizing harmful gases and soot down to comp
 ounds with diminished damaging effects. Though promising as they are\, the
 se kinds of technologies are generally made up of expensive and rare noble
  metals such as platinum\, gold\, and palladium. In addition to this obser
 vation\, a major problem associated with these catalysts is their low soot
  oxidation efficiencies. Because of these reasons\, catalysts of this natu
 re have been widely criticized for their high cost yet poor efficiency. To
  overcome this barrier\, alternative catalysts and designs have been inves
 tigated to meet the demands of a cheaper and more efficient oxidizing mate
 rial. One area of that has received much attention in recent years [are] s
 ilver metal-supported catalysts. Catalysts of this nature\, which are meta
 l oxides shielded in silver nanoparticles\, have displayed both high therm
 al stability and oxidizing efficiency despite their sacrifice of cost. How
 ever\, the notable feature that highlights their attractiveness and has ar
 oused curiosity in this area is their ability to outperform their homogeno
 us counterparts. During this seminar I will highlight the unique working m
 echanism behind these materials and the influence of silver nanoparticles 
 on their catalytic activity and thermal stability. Future implications for
  this field and potential integrations for this technology will also be di
 scussed to highlight the context and importance of this study.\n\nChen\, L
