Modification of edge mode dynamics of oxidized Ni 80 Fe 20 thin film edges

May 20, 2010
Author(s)
Meng Zhu, Robert D. McMichael
We use ''edge mode'' ferromagnetic resonance (FMR) to probe the magentic properties of oxidized Ni 80Fe 20 (Py) nanostripe edges. The oxidation is carried out using either oxygen plasma or thermal annealing in an oxygen ambient. We find that for both

Challenges in Sustainable Polymeric Materials

Author(s)
Kathryn L. Beers, Christopher M. Stafford
While there are many societal and economic factors that contribute to a sustainable civilization, there are also real technical and scientific problems that must be solved to provide the materials necessary to make progress towards the goal of

Molecular Mass Distribution Measurement by Mass Spectrometry

May 19, 2010
Author(s)
William E. Wallace, Charles M. Guttman
This NIST Recommended Practice Guide presents a method using mass spectrometry to make a quantitative determination of the molecular mass distribution of narrow polydispersity synthetic molecular materials. The main obstacle for converting an oligomer

Monitoring Photothermally Excited Nanoparticles via Multimodal Microscopy

May 19, 2010
Author(s)
Matthew L. Clarke, Shin G. Chou, Jeeseong Hwang
Generation of heat using optically excited nanoparticles can be beneficial or detrimental depending on the application. Therefore, clinically applicable studies are being pursued in an effort to achieve safe practices of nanoparticle-induced hyperthermia
