چکیده
absorbing inner core surrounded by a non-absorbing shell—revealed that many particles are actually shaped differently. • Measurements of black carbon in the atmosphere around urban centers in California indicate that when black carbon mixes with other atmospheric components, the particle’s ability to absorb light and generate heat is significantly less pronounced than often simulated in global climate models. Impact. Various ASR research efforts coupled laboratory and field measurements to yield a better understanding of the concentrations and physical characteristics of aerosols containing black carbon. The research confirmed that black carbon contamination More Like Shades of Gray: The Effects of Black Carbon in Aerosols

Using MODIS data for nonlinear hazard analysis of the Middle East aerosols
Aerosols are among the most important of atmospheric pollutants observed like the microscopic particulate matter in the lower parts of the troposphere. The main purpose of this study is introducing a new method based on satellite images processing results and nonlinear analysis (fractal based) to investigate the origin and dynamical mechanism of aerosols distribution in North Africa and the Mid...
متن کاملEffect of carbon black content on the microwave absorbing properties of CB/epoxy composites
To prevent serious electromagnetic interference, a single-layer and double layer wave-absorbing coating employing complex absorbents composed of carbon black with epoxy resin as matrix was prepared. The morphologies of carbon black /epoxy composites were characterized by scanning electron microscope and atomic force microscope, respectively. The carbon black particles exhibit obvious polyarom...
متن کاملRefractive Index and Absorption Attribution of Highly Absorbing Brown Carbon Aerosols from an Urban Indian City-Kanpur
Atmospheric aerosols influence Earth's radiative balance, having both warming and cooling effects. Though many aerosols reflect radiation, carbonaceous aerosols such as black carbon and certain organic carbon species known as brown carbon have the potential to warm the atmosphere by absorbing light. Black carbon absorbs light over the entire solar spectrum whereas brown carbon absorbs near-UV w...
متن کاملCarbon black-intercalated reduced graphene oxide electrode with graphene oxide separator for high-performance supercapacitor
We present a general study on a high performance supercapacitor based on intercalated reduced graphene oxide with carbon black nanoparticles. Graphene oxide sheets were synthesized by oxidation and exfoliation of natural graphite and were reduced using hydroiodic acid in the presence of carbon black nanoparticles. Graphene paper was fabricated by one-step procedure via simultaneous reducing and...
متن کاملEffect of Carbon Black Content on Curing Behavior of Polysulfide Coatings
Polysulfide is well known elastomer for use in aerospace applications due to providing flexible coating and chemically resistant sealants. In this work, the effects of carbon black content on curing behavior of polysulfide elastomer were investigated and Rheological properties for samples with different filler content 15, 20 and 25 phr were evaluated by rheometric mechanical spectrometer RMS. A...
