Size Distribution of HULIS in Ambient Aerosols at a Rural Site in South China
TL;DR: In this paper, the abundance and size distributions of HULIS in ambient aerosols were measured in a rural location in South China at a time with a visible presence of crop residue burning.

Heterogeneous nucleation of ice on anthropogenic organic particles collected in Mexico City
TL;DR: In this article, the onset of heterogeneous ice nucleation was observed as a function of particle temperature (Tp), relative humidity (RH), nucleation mode, and particle chemical composition which is influenced by photochemical atmospheric aging.

TL;DR: In this paper, the composition of the residual particles within cirrus crystals after the ice was sublimated was determined in situ, showing that mineral dust and metallic particles are the dominant sources of residual particles, whereas sulfate and organic particles are underrepresented, and elemental carbon and biological materials are essentially absent.
Formation of light absorbing organo-nitrogen species from evaporation of droplets containing glyoxal and ammonium sulfate
TL;DR: Using aerosol mass spectrometry, it is shown that particle-phase organics with high N:C ratios were formed when ammonium salts were used, and that the presence of sulfate ions promoted this chemistry.

Humic-like substances (HULIS) in springtime aerosols at a high-altitude background station in the western North Pacific: Source attribution, abundance, and light-absorption
TL;DR: In this article , the authors determined various key light-absorbing characteristics of HULIS including mass absorption cross-section, absorbing component of the refractive index (kHULIS), and absorption Ångström exponent (AAEHULIS) based on ground-based aerosol light absorption measurements.

TL;DR: A unifying model framework describing the atmospheric evolution of OA that is constrained by high–time-resolution measurements of its composition, volatility, and oxidation state is presented, which can serve as a basis for improving parameterizations in regional and global models.

TL;DR: In this article, the authors reviewed existing knowledge with regard to organic aerosol (OA) of importance for global climate modelling and defined critical gaps needed to reduce the involved uncertainties, and synthesized the information to provide a continuous analysis of the flow from the emitted material to the atmosphere up to the point of the climate impact of the produced organic aerosols.

Determination of bacterial load by real-time PCR using a broad-range (universal) probe and primers set.
TL;DR: The design and evaluation of a set of universal primers and probe for the amplification of 16S rDNA from the Domain Bacteria to estimate total bacterial load by real-time PCR is reported, and the number of anaerobic bacteria estimated by the universal probe and primers set in carious dentine was 40-fold greater than the totalacterial load detected by culture methods, demonstrating the utility of real- time PCR in the analysis of this environment.
