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.

Intrinsic Negative Chargeability of Soft Clays [PDF]
ASEG Extended Abstracts, 2003 Lithologies with high clay contents can have negative chargeability. This response is usually attributed to geometric effects in induced polarization and electromagnetic surveys. Negative chargeability has also been noted in laboratory studies, but has remained unexplained.

Instability Characteristics of and Control Techniques for Mudstone–Clay Composite Roof Roadways
Applied SciencesIn China’s northwest mining areas, shallow buried coal seams commonly feature double soft composite roof structures of mudstone and clay, resulting in poor roadway stabilization and proving challenging for effective roadway-surrounding rock (RSR) control.

Effect of electrolyte on the microstructure and yielding of aqueous dispersions of colloidal clay
, 2015 Na-montmorillonite is a natural clay mineral and is available in abundance in nature. The aqueous dispersions of charged and anisotropic platelets of this mineral exhibit non-ergodic kinetically arrested states ranging from soft glassy phases dominated ...

Reducing settlement of soft clay using different grouting materials
Journal of the Mechanical Behavior of Materials, 2022 Different injection material types were tried in the injection of soft clay, such as lime (L), silica fume (SF), and leycobond-h (LH). In this study, experiments were made to study the effect of injection on soft clay consolidation settlement.

ESTIMATING LOAD-DISPLACEMENT BEHAVIOR OF SOFT CLAYS
Proceedings of International Structural Engineering and Construction, 2016 Prediction of long term settlement of soft soils below civil engineering structures is an important issue in geotechnical engineering. The data from laboratory consolidation tests are used to estimate the ultimate settlement and problems arise in predicting settlement-time behavior in the field.

Characterization and engineering properties of the NGTS Onsøy soft clay site
AIMS Geosciences, 2019 In the 1960s, NGI investigated numerous potential research sites and established the first Onsoy soft clay site in 1968. In 2016, the NGTS project established five research sites, one of which is the NGTS Onsoy soft clay site.
