Aerosols in Astrophysics

Solid phase material exists in low density astrophysical environments, from stellar atmospheres to interstellar clouds, from current times to early phases of the universe. We consider the origin, composition and evolution of solid phase materials in the particular case of stellar outer atmospheres, as representative of many conditions. Also considered are the dynamics and interactions in circum...

Exposures to acidic aerosols.

Ambient monitoring of acid aerosols in four U.S. cities and in a rural region of southern Ontario clearly show distinct periods of strong acidity. Measurements made in Kingston, TN, and Steubenville, OH, resulted in 24-hr H+ ion concentrations exceeding 100 nmole/m3 more than 10 times during summer months. Periods of elevated acidic aerosols occur less frequently in winter months. The H+ determ...

Administration of Therapeutic Aerosols

ventilation, and airway geometry, will deposit to varying degrees throughout the respiratory tract.1 Aerosols account for the spread of certain infectious lung diseases, as well as exposure to noxious agents resulting in interstitial lung disease and even malignancy. Aerosols have been employed as a means of drug delivery in the treatment of respiratory disorders. The theoretical advantages of ...
