Size analysis of automobile soot particles using field-flow fractionation

Article Abstract:

Automobile exhaust is a combination of particulate matter and toxic gases, and releases soot particles from the engine into the air. The soot samples are analyzed by a separation technique called field-flow fractionation, which uses a three-step process, and determined that turbo-charged diesel engines and gasoline engines with a catalytic converter both emit more particles smaller that 100 nanometers.

Tempera-painted dosimeters for environmental indoor monitoring: a spectroscopic and chemometric approach

Article Abstract:

Researchers from Italy evaluated the environmental risks in the deterioration of paintings in museums and galleries by using dosimeters that reproduce the structure of painting as closely as possible and then aged in special chambers. The results of the natural and artificial aging of the paintings were compared.

Photoreductive dehalogenation of halogenated benzene derivatives using ZnS or CdS nanocrystallites as photocatalysts

Article Abstract:

Research indicates that photocatalytic reduction of halogenated benzene derivatives is possible. As a result, a decrease in toxicity is achieved. Accompanying charts and graphs provide additional statistical data.
