Uptake And Accumulation Of Engineered Nanomaterials By Agricultural Crops And Associated Risks In The Environment And Food Safety, Yingqing Deng
Uptake And Accumulation Of Engineered Nanomaterials By Agricultural Crops And Associated Risks In The Environment And Food Safety, Yingqing Deng
Doctoral Dissertations
Engineered nanomaterials (ENMs) are being discharged into the environment and to agricultural fields, with unknown impacts on crop species. This study focused on the bioaccumulation of engineered nanomaterials into crops and the associated impact on plant growth and plant uptake of secondary contaminant. Investigations into the interactions between nanomaterials and agricultural plants will provide a more developed understanding of nanomaterials implications in the environment; in addition, evaluations of the risks associated with plant-nanomaterials interactions will provide guidelines for safe use of nanomaterials in agriculture. In the screening study on phytotoxicity, carbon-based nanoparticles (NPs) including C60, MWCNTs, NH2 …
Kinetics And Dynamics Of Electrophoretic Translocation Of Polyelectrolytes Through Nanopores, Harshwardhan Katkar
Kinetics And Dynamics Of Electrophoretic Translocation Of Polyelectrolytes Through Nanopores, Harshwardhan Katkar
Doctoral Dissertations
The idea of sequencing a DNA based on single-file translocation of the DNA through nanopores under the action of an electric field has received much attention over the past two decades due to the societal need for low cost and high-throughput sequencing. However, due to the high speed of translocation, interrogating individual bases with an acceptable signal to noise ratio as they traverse the pore has been a major problem. Experimental facts on this phenomenon are rich and the associated phenomenology is yet to be fully understood. This thesis focuses on understanding the underlying principles of polymer translocation, with an …
