Impact of nano sized SiC and Gr on mechanical properties of aerospace grade Al7075 composites by M. Ravikumar, Rudra Nail

“…The mechanical properties such as ultimate tensile and compressive strength of the developed MMCs could be improved by addition of SiC particulates compared to base material. Further, the strength of developed hybrid composites was found to be decreased by adding of solid lubricant such as graphite (Gr) particulates along with hard ceramic particulates. …”

Global Warming, Air Pollution and Health by Robin Attfield

“…Other impacts are mediated through the air pollution that results from emissions from vehicles in the form of a cocktail of carbon oxides including carbon monoxide, nitrogen dioxide and particulates. Most of the world’s cities have streets with unsafe pollution levels, and one child’s death in Britain has been officially ascribed to air pollution (BBC 2020).  …”

PPARs in Alveolar Macrophage Biology by Monica R. Smith, Theodore J. Standiford, Raju C. Reddy

“…PPARs, most notably PPAR-γ, play a crucial role in regulating the activation of alveolar macrophages, which in turn occupy a pivotal place in the immune response to pathogens and particulates drawn in with inspired air. In this review, we describe the dual role of the alveolar macrophage as both a first-line defender through its phagocytotic activity and a regulator of the immune response. …”
