Fine dispersion of the two materials may lead to poor charge transfer through the layers with imbalanced charge–carrier mobility (order of magnitude of hole mobility < electron mobility), thereby lowering the FF. The essential requirements of these devices are (1) sensitive control over the ...

A specific type of organism can establish one of three possible patterns of dispersion in a given area: arandom pattern; anaggregatedpattern, in which organisms gather inclumps;or auniform pattern, with a roughly equal spacing of individuals. The type of pattern often results from the nature of...
The air pollution removal capacities of urban green spaces were limited and could remove less than 10% of PM10 emissions in the city [3]. Trees in urban green spaces help to remove air pollution, while trees can also produce negative effects like pollen pollution, limiting pollution dispersion ...
As public awareness of ecological preservation grows and the connection between economic development and ecological protection strengthens, research on the pattern of ecological security is gradually transitioning into a systematic coupled analysis of natural ecology and economic and social development [21]....

affected the strength of trait dispersions for all the five traits, but ontogenetic stages influenced both the strength and direction of trait dispersions, which depended on the traits selected; (3) the relative importance of soil, topography and space to trait dispersion varied with ontoge...
(Fig.1A), the pair-wise comparison tests were significant for all pairs of agricultural land-use types (Supplementary TableS1). The dispersion of soil bacterial communities within each type of agricultural land use was examined by measuring the distance between the centroid. Bacterial community ...
Used to study lithographic pattern and latex dispersion, glass fragments and crystals. Limitations of Phase Contrast Microscope Not ideal for thick specimen Halo effect and shade-off are common Condenser annulus limit the aperture, hence decrease resolution ...
Dispersion of the seed is defined as the dissemination and transport of seed from one place to another away from their parent plant by many external agents or on their own. There are mainly six modes of dispersion. Barochory:It is the dispersion of seed by gravity. The heavier seed detached...
