Application of the SBAS-DInSAR technique for deformation monitoring in Tunis City and Mornag plain
Geomatics, Natural Hazards & Risk, 2020 The ground deformation phenomena are the result of the application of natural stress (tectonic) or anthropogenic stress (overexploitation of groundwater, embankment) on the soil. The land deformation may cause several impacts on the environment and human

Investigation of gold nanorods as a sensing material in plasmonic sensor for triclopyr butotyl detection [PDF]
, 2020 Gold nanorods (GNRs) have a unique optical property of metal nanoparticles (MNPs) due to the localised surface plasmon resonance (LSPR) effect, which depends on the size, shape and dielectric property of the surrounding medium.
