Microfluidic Paper-Based Analytical Device for Aerosol Oxidative Activity [PDF]

open access: yesEnvironmental Science & Technology, 2012
Human exposure to particulate matter (PM) air pollution has been linked with respiratory, cardiovascular, and neurodegenerative diseases, in addition to various cancers. Consistent among all of these associations is the hypothesis that PM induces inflammation and oxidative stress in the affected tissue.

Gate control of a quantum dot single-electron spin in realistic confining potentials: anisotropy effects

open access: yes, 2008
Among recent proposals for next-generation, non-charge-based logic is the notion that a single electron can be trapped and its spin can be manipulated through the application of gate potentials.
