Effect of the Oxygen Concentration and Temperature on Thermal Decomposition of NO in an Inert Gas.

Nitrous oxide (NO) is one of the greenhouse gases that contribute to global warming. But, there are few methods for controlling NO directly. It is essential to reduce NO to solve environmental problems.

Characterization of calcium carbonate sorbent particle in furnace environment.

The oxy-fuel combustion system is a promising technology to control CO₂ and NO(x) emissions. Furthermore, sulfation reaction mechanism under CO₂-rich atmospheric condition in a furnace may lead to in-furnace desulfurization. In the present study, we evaluated characteristics of calcium carbonate (CaCO₃) sorbent particles under different atmospheric conditions.

Practical engineering approaches and infrastructure to address the problem of marine debris in Korea.

As a solution to the problem of persistent solid marine debris, a nationwide project began in Korea in 1999 to develop and popularize fundamental changes to the infrastructure. The ten year project, called "A Practical Integrated System for Marine Debris," consists of four linked types of technology: prevention, deep-water survey, removal and treatment (recycling). These reflect the characteristics of marine debris, which though widespread, vary by location and time of generation.
