Constraining the parameter space of comet simulation experiments [PDF]
, 2018 Our interpretation of the data returned by Rosetta and other cometary missions is based on the predictions of theoretical models and the results of laboratory experiments. For example, Kossacki et al. (2015) showed that 67P's surface hardness reported by

Source-sink processes of marine black carbon in the context of "carbon neutrality"
地质科技通报Objective Black carbon is a carbonaceous mixture formed by the incomplete combustion of biomass and fossil fuels. Since black carbon has a high carbon content and an aromatized molecular structure, it can persist in the natural environment, suggesting ...

Dissolved black carbon in Antarctic lakes: Chemical signatures of past and present sources
Geophysical Research Letters, 2016 The perennially ice‐covered, closed‐basin lakes in the McMurdo Dry Valleys, Antarctica, serve as sentinels for understanding the fate of dissolved black carbon from glacial sources in aquatic ecosystems.

Global anthropogenic emissions of particulate matter including black carbon
, 2016 . This paper presents a comprehensive assessment of historical (1990–2010) global anthropogenic particulate matter (PM) emissions including the consistent and harmonized calculation of mass-based size distribution (PM1, PM2.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Production of Carbon Black in Turbulent Spray Flames of Coal Tar Distillates
Applied Sciences, 2021 Conventional carbon black production occurs by pyrolysis after heavy aromatic feedstock is injected into the post-combustor region of furnace black reactors. The current work examines the conversion of the coal tar distillate in turbulent spray flames to

Reducing Black Carbon from Wood Burning in Fairbanks, Alaska [PDF]
, 2014 Fairbanks, Alaska has been home to air quality concerns for years. Heat sources like wood boilers emit black carbon, a pollutant akin to soot. In Fairbanks\u27s harsh winters, black carbon is trapped close to the earth and creates health problems for ...
