<i>iVirtualWorld</i>: A Domain-Oriented End-User Development Environment for Building 3D Virtual Chemistry Experiments
… Nevertheless, many virtual world users (e.g. chemistry or biology teachers) neither have nor are expected to learn programming skills. This situation has been a barrier to broader adoption of virtual worlds in education. This dissertation seeks to ease the process of building virtual …

Sulfate Dynamics and Base Cation Release in a High Elevation Appalachian Forest Soil
… a series of batch adsorption and desorption experiments. Reconstructed soil profiles were then subjected to water leaching as the preliminary step to a base release study in which each soil will be placed under simulated acid rain and evaluated for base cation release and subsequent changes …

MEASUREMENTS OF ATMOSPHERIC RADICALS IN AMBIENT AND INDOOR ENVIRONMENTS: OUTDOOR-INDOOR RELATIONSHIPS, INDOOR FORMATION MECHANISMS, AND INSTRUMENTAL ANALYSIS
… atmospheric oxidation, critically altering the chemistry of the air we breathe. Radical reactions initiate oxidation of volatile organic compounds (VOCs), which in the presence of nitrogen oxides (NOx) can form ozone and secondary organic aerosols (SOA)—air pollutants affecting human health and …

The development of integrated chemistry-based experiments implications for the teaching of environmental chemistry in the Vietnamese context
A survey of environmental chemistry laboratory experiments in the Journal of Chemical Education (ACS) and Education in Chemistry (RCS) has been carried out from 1969 to the present. The experiments have been categorized as being related to the areas of either air, water or soil. Over the same …

Insights into the radiation Chemistry of FLASH Radiation Therapy
… under FLASH conditions.</p> <p>For radiation chemistry studies, the spin trap DMPO was used to detect hydroxyl radicals (•OH) and hydrogen radicals (•H) in normoxic triple-distilled water. Irradiations were performed using a modified Varian Clinac 21X. Spin adducts (•DMPO-OH, •DMPO-H) were …

Coupling of Oxidation-Reduction Reactions of Chromium, Iron and Manganese: Implications for the Fate and Mobility of Chromium in Aquatic Environments
… to treat simulated drinking water solutions. Experiments have evaluated the effects of pH, dissolved oxygen, and common anions on Cr(VI) removal during batch EC treatment. In addition, the presence of humic acid (HA) inhibited the rate of Cr(VI) removal in electrocoagulation, with slower …
