A highly luminescent freestanding film composed of the quantum cluster, Au(15), was prepared. We studied the utility of the material for specific metal ion detection. The sensitivity of the red emission of the cluster in the composite to Cu(2+) has been used to make a freestanding metal ion sensor, similar to pH paper. The luminescence of the film was stable when exposed to several other metal ...

concern for the environment is a constantly growing phenomenon. awareness of most peopleand governments in the world with regard to this question has risen. sometimes, this position is inverselyproportional to economic growth, leading to a situation where a more environmental stance on the part of end users has often not been supported by more restrictive environmental protection laws. this stu...

Collaboration across cultural and national boundaries has become a means to address critical global problems. This paper presents a case study examining the dynamics and processes that participants used to support transnational collaboration in the policy areas of public health and environmental protection. The case studied is AIRNow-International Shanghai, a collaborative project between the U...

An adjoint model for the internationally used Community Multiscale Air Quality (CMAQ) modeling platform of the U.S. EPA is developed. The adjoint version for CMAQ (CMAQ-ADJ) provides the user community with forward (decoupled direct method or DDM) and backward (adjoint) sensitivity analysis capabilities. Current implementation is for gas-phase processes. Discrete adjoints are implemented for al...

One of the central tenets of a property rights approach to environmental protection holds not only that people respond to incentives, but also that the structure of entitlements conveyed by property rights affects incentives. It follows that a careful study of entitlements in various environmental contexts can provide a foundation for greater understanding about why human behavior can be so env...
