Response Mechanism of Litter to Soil Water Conservation Functions Under the Density Gradient of Robinia pseudoacacia L. Forests in the Loess Plateau of the Western Shanxi Province [PDF]

Plants
In the ecologically fragile western Shanxi Loess region, stand density regulation of artificial Robinia pseudoacacia L. forests plays a crucial role in sustaining the water regulation functions of the litter-soil system, yet multi-scale mechanistic ...

3D Correlative Imaging of Lithium Ion Concentration in a Vertically Oriented Electrode Microstructure with a Density Gradient [PDF]

Advanced Science, 2022
The performance of Li+ ion batteries (LIBs) is hindered by steep Li+ ion concentration gradients in the electrodes. Although thick electrodes (≥300 µm) have the potential for reducing the proportion of inactive components inside LIBs and increasing ...

Anomalous optical gradient force induced by polarization-tuned antisymmetry in energy density gradient [PDF]

Nanophotonics
The spatial inhomogeneity of electromagnetic energy density in an optical field typically gives rise to conservative gradient forces, which serve as the fundamental mechanism for trapping nanoparticles in optical tweezers.
