Summary of "β-Cyclodextrin based air filter for high-efficiency filtration of pollution sources."

Airborne particulate matter (PM) pollution has become a serious environmental problem. Thus, there is a need for the development of air filters with satisfactory overall performance. In this paper, we develop a kind of β-cyclodextrin (β-CD) based air filter with high strength, which has not only high filtration efficiency (about 99%) but also good air permeability (the pressure drop is only 45Pa). Especially after long-term application, the pression drop of β-cyclodextrin based was less than half of the commercial air-filter. Additionally, the material can capture the toxic gasous chemicals (e.g. formaldehyde and SO). The introduction of β-CD is supposed to be the key factor for improvement of air filter.

Medical and Biotech [MESH] Definitions

Water pollution from a variety of diffuse sources carried over or through the ground and into water sources such as LAKES; RIVERS; WETLANDS; coastal waters; and GROUNDWATER. Such diffuse sources include roadways and parking lots (GASOLINE; HEAVY METALS; and motor oil), lawns or agricultural land (excess FERTILIZERS, livestock excrement, and PESTICIDES), landfill seepage, and construction sites (chemicals and trash used in construction processes).

Information application based on a variety of coding methods to minimize the amount of data to be stored, retrieved, or transmitted. Data compression can be applied to various forms of data, such as images and signals. It is used to reduce costs and increase efficiency in the maintenance of large volumes of data.

Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks.
