Surface Temperature and Surface-Layer Turbulence in a Convective Boundary Layer [PDF]

Boundary-Layer Meteorology, 2013
Previous laboratory and atmospheric experiments have shown that turbulence influences the surface temperature in a convective boundary layer. The main objective of this study is to examine land-atmosphere coupled heat transport mechanism for different stability conditions.

Surface layer of layered minerals

Вісник Київського національного університету імені Тараса Шевченка. Серія Геологія
Background. The surface layer of layered minerals such as graphite, molybdenum disulfide (MoS₂), and molybdenum diselenide (MoSe₂) can be regarded as an ultrathin film, with a thickness ranging from approximately 2 nm in the in-plane direction to about 6

Measurement report: Vertical distribution of biogenic and anthropogenic secondary organic aerosols in the urban boundary layer over Beijing during late summer [PDF]

Atmospheric Chemistry and Physics, 2021
Secondary organic aerosol (SOA) plays a significant role in atmospheric chemistry. However, little is known about the vertical profiles of SOA in the urban boundary layer (UBL).

Measurement report: Optical properties and sources of water-soluble brown carbon in Tianjin, North China – insights from organic molecular compositions [PDF]

Atmospheric Chemistry and Physics, 2022
Brown carbon (BrC) aerosols exert vital impacts on climate change and atmospheric photochemistry due to their light absorption in the wavelength range from near-ultraviolet (UV) to visible light.

Large contributions of biogenic and anthropogenic sources to fine organic aerosols in Tianjin, North China [PDF]

Atmospheric Chemistry and Physics, 2020
In order to better understand the molecular composition and sources of organic aerosols in Tianjin, a coastal megacity in North China, ambient fine aerosol (PM2.5) samples were collected on a day/night basis from November to December 2016 and from May to

Vertical distribution of particle-phase dicarboxylic acids, oxoacids and α-dicarbonyls in the urban boundary layer based on the 325 m tower in Beijing [PDF]

Atmospheric Chemistry and Physics, 2020
Vertical distributions of dicarboxylic acids, oxoacids, α-dicarbonyls and other organic tracer compounds in fine aerosols (PM2.5) were investigated at three heights (8, 120 and 260 m) based on a 325 m meteorological tower in urban Beijing ...

Surface layers of bacteria [PDF]

Microbiological Reviews, 1991
Since bacteria are so small, microscopy has traditionally been used to study them as individual cells. To this end, electron microscopy has been a most powerful tool for studying bacterial surfaces; the viewing of macromolecular arrangements of some surfaces is now possible.
