Spatial variation and fractionation of bed sedimentborne
An investigation was conducted to examine the spatial variation and fractionation of bed sedimentborne Cu, Zn, Pb, and Cd in a stream system affected by acid mine drainage. The pH had a major control on the spatial variation pattern of soluble, exchangeable, and carbonatebound Cu, Zn, and Cd. There was a prominent concentration peak of carbonatebound, oxidebound, and organicbound metals

Sampling was undertaken to investigate spatial variation of metal content in soil near mine tailings. Chromium and uranium were related to soil organic matter content uranium showed a spatial trend. Spatial variation was scale dependent, variation of copper was not scale‐invariant.
Resolving spatial and energetic distributions of trap
12 days ago · The high efficiency of hybrid inorganicorganic perovskite solar cells is mainly limited by defects that trap the charge carriers and lead to unproductive recombination. Ni et al. used drivelevel capacitance profiling to map the spatial and energetic distribution of trap states in both polycrystalline and singlecrystal perovskite solar cells.
Spatial Distribution and Variation of Heavy Metals and
The spatial distribution and variation of six heavy metals and metalloid in soil of Zhuji Lipu copper mining area was studied using geostatistics approaches combined with GIS. These elements included Pb, As, Cr, Cu, Zn and Ni. The statistical analyses showed that concentrations of these elements were lognormal distribution. Concentrations of Pb, As, Cu, Zn and Ni were strongly correlated with
