Journal ArticleDOI
Nanoceria exhibit redox state-dependent catalase mimetic activity
Talib Pirmohamed,Janet M. Dowding,Sanjay Singh,Brian Wasserman,Eric Heckert,Ajay S. Karakoti,Jessica E. S. King,Sudipta Seal,William T. Self +8 more
TL;DR: It is found that cerium oxide nanoparticles exhibit catalase mimetic activity, which correlates with a reduced level of cerium in the +3 state, in contrast to the relationship between surface charge and superoxide scavenging properties.
Journal ArticleDOI
The role of cerium redox state in the SOD mimetic activity of nanoceria
TL;DR: X-ray photoelectron spectroscopy and UV-visible analyses of nanoceria treated with hydrogen peroxide demonstrate that a decrease in the Ce 3(+)/4(+) ratio correlates directly with a loss of SOD mimetic activity.
Journal ArticleDOI
Anti‐inflammatory Properties of Cerium Oxide Nanoparticles
Suzanne M. Hirst,Ajay S. Karakoti,Ron Tyler,Nammalwar Sriranganathan,Sudipta Seal,Christopher M. Reilly +5 more
TL;DR: It is suggested that cerium oxide nanoparticles are well tolerated in mice and are incorporated into cellular tissues and therefore serve as a novel therapy for chronic inflammation.
Journal ArticleDOI
One dimensional nanostructured materials
TL;DR: In this paper, the authors focus on the science behind the synthesis and properties of the ODNS rather than the device fabrication, and discuss current research related to environment and toxicology effects and current challenges in this rapidly evolving field.
Journal ArticleDOI
Ultralight multiwalled carbon nanotube aerogel.
Jianhua Zou,Jianhua Liu,Ajay S. Karakoti,Amit Kumar,Daeha Joung,Qiang Li,Saiful I. Khondaker,Sudipta Seal,Lei Zhai +8 more
TL;DR: The excellent compression recoverable property, hierarchically porous structure with large surface area, and high conductivity grant the MWCNT aerogels exceptional pressure and chemical vapor sensing capabilities.
