Influence of EDTA Coverage Density on Optical Fiber Sensor for Heavy Metal Ion Detection

Nano Select, EarlyView.
This study investigates the influence of chelating agent coverage on the performance of optical fiber sensors for heavy metal ion detection. Ethylenediaminetetraacetic acid (EDTA) was employed to functionalize single‐mode 28 optical fibers (SMF‐28), and the influence of surface coverage uniformity on zinc ion sensing performance was investigated ...

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Arbuscular mycorrhizal fungal inoculation increases the bioavailability of zinc and iron in wheat grain

PLANTS, PEOPLE, PLANET, EarlyView.
Bread wheat is an important crop that supplies calories and nutrients to the global population. Enhancing the concentrations and bioavailability of essential micronutrients in wheat is crucial for human nutrition, and we investigated whether arbuscular mycorrhizal (AM) fungi can contribute to the biofortification of wheat.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Triple-Coil Inductive Debris Sensor with Special Shielded Coils for Depressing Interference of Dielectric Components

Procedia Manufacturing, 2019
Abstract Dielectric contents, such as air bubbles and water droplets in the lubricating oil, can severely interfere with the performance of inductive debris sensor due to the effect of coil parasitic capacitance. This study proposes a special mesh screen that can effectively eliminate the interference to a triple-coil inductive sensor to avoid false ...
