 Air Pollution: Sources, Impacts and Controls
The problem of air pollution has become a global issue, driven by rapid economic growth, industrialization, and urbanization. Pollutants directly emitted into the atmosphere include nitrogen oxides, carbon monoxide, sulphur oxides, particulate matter (PM), volatile organic compounds, carbonaceous particles, dust, and sea-salt. Secondary ... | | Advanced Materials for Membrane Fabrication and Modification
Membranes are an energy efficient separation technology that are now the basis for many water treatment and food processing applications. However, there is the potential to improve the operating performance of these separations and to extend the application of membranes to energy production, gas separations, organic solvent-based... | | |

Indra's Net and the Midas Touch: Living Sustainably in a Connected World
We live today in a global web of interdependence, connected technologically, economically, politically, and socially. As a result of these expanding and deepening interdependencies, it has become impossible fully to control -- or foretell -- the effects of our actions. The world is rife with unintended consequences. The first law of human... | | Quantum Mechanics of Molecular Structures
The world we live in is filled with molecules. Starting with oxygen and nitrogen
in the atmosphere, water, carbon dioxide, and ammonia are all molecules. Furthermore,
plants and animals are all composed of molecules. In the field of chemistry,
which is regarded as science for molecules, it has been one of the most important
and... | | |
