The Effect on Wireless Sensor Communication When Deployed in Biomass
Sensors, 2011 Wireless sensor networks (WSN) have been studied in a variety of scenarios over recent years, but work has almost exclusively been done using air as the transmission media.

Advanced Functional Materials, EarlyView.A thermodynamic model that incorporates ferroelectric, antiferroelectric, and antiferrodistortive orders of PbZrO3${\rm PbZrO}_3$ is established and parameterized based on experimental measurements and first‐principles calculations. We derive a Clapeyron‐like equation for describing the temperature‐dependence of critical electric fields for the ...

Substances with zero static permittivity
Scientific Reports, 2022 AbstractThe structure of materials with a negative electric susceptibility has been determined. Their electrical properties correspond to vanishing static dielectric permittivity. We give a theoretical explanation of anomalous polarization of powders observed in experiments and the mechanism of emergence in an aerosol cloud of an electric field, which ...

Ferroelectric Polarization Enabled Threshold Voltage Modulation in High Electron Mobility Transistor
Advanced Functional Materials, EarlyView.A comprehensive model is developed to capture the coupled electrostatics of a ferroelectric capacitor and a metal‐insulator‐semiconductor high electron mobility transistor (MISHEMT) connected in ferroelectric‐metal high electron mobility transistor (FeMHEMT) configuration.

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems
Advanced Functional Materials, EarlyView.Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...
