Improving indoor air quality, health and performance within environments where people live, travel, learn and work
Frank J. Kelly,Julia C. Fussell +1 more
TL;DR: The role of air purification technologies in key indoor micro-environments demonstrates that air filtration produces clear reductions in indoor pollution concentrations as discussed by the authors, however, this is not the case for all environments.

TL;DR: The study revealed that the use of air purifiers with windows kept closed (natural ventilation) can lead to a significant reduction in terms of indoor-to-outdoor concentration ratios, and for low ACH values, the reduction is quite negligible.

Graphene Oxide-Modified Polyacrylonitrile Nanofibrous Membranes for Efficient Air Filtration
TL;DR: The most common form of PM2.5, referred to as smaller than 2.5 μm, is the most common type of PM and is referred to by as mentioned in this paper.
Impact of the air pollution
TL;DR: In this article, the authors present important environment issues that can impact human health and life on Earth, and present important resources that can be used to improve human health, life, and well-being.

Chemical characterization of particulate emissions from diesel engines: A review
TL;DR: In this paper, the chemical properties of particulate matter (PM) in diesel vehicle exhaust at a time when emission regulations, diesel technology development, and particle characterization techniques are all undergoing rapid change are examined.

Physical characterization of particulate emissions from diesel engines: a review
TL;DR: In this paper, the effects of aftertreatment devices such as particle traps and catalytic converters on diesel particle properties are discussed, and a selection of systems for dilution, conditioning and measuring is shown.

Dispersal in microbes: fungi in indoor air are dominated by outdoor air and show dispersal limitation at short distances
TL;DR: Results show that at the local level, outdoor air fungi dominate the patterning of indoor air, providing additional support for the growing evidence that dispersal limitation, even on small geographic scales, is a key process in structuring the often-observed distance–decay biogeographic pattern in microbial communities.

Signature size distributions for diesel and gasoline engine exhaust particulate matter
TL;DR: In this article, the size distributions of diesel exhaust particulate matter measured from a large number of vehicles and test engines, using a variety of diesel fuels, collapse onto a single characteristic lognormal distribution, when normalized by total particle number and plotted against a scaled diameter.
