Abstract: The Australian native hemi-aquatic herb C. helmsii (Crassulaceae) is a copper (Cu) accumulator, tolerant to a wide range of climatic conditions and able to concentrate >9000 μg Cu g−1 in its living tissues. These characteristics suggest practical potential for… read more here.

Abstract: We present a sweep-stick mechanism for heavy particles transported by a turbulent flow under the action of gravity. Direct numerical simulations show that these particles preferentially explore regions of the flow with close to zero… read more here.
