Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effe ...

DESCRIPTION provided by applicant This proposal will assess the quantitative capabilities of surface enhanced Raman scattering SERS detection of cocaine and marijuana metabolites in urine samples Combining low cost instrumentation and novel chemical sensing provides an innovative new approach for diagnosing illicit drug use Current methods use a colorimetric indicator to screen specimens fo ...

DESCRIPTION provided by applicant The increasing output of new integral membrane protein IMP structures is partially due to the availability of an increasing number of chemical variables such as detergents detergent like molecules lipids and solubilizing stabilizing additives It is clear that specific combinations and concentrations of these different variables are often necessary to impr ...

DESCRIPTION provided by applicant Crystallization followed by subsequent structure determination is a major step in understanding the structure function relationship of macromolecules Understanding macromolecule structure has become a key part in the development of new pharmaceuticals and is a major area of NIH research Crystallization however is also the rate limiting step despite techno ...
