Article Synopsis
- - Researchers observed ferroelectric properties in a 2D phase of water ice, created by confining it between two graphene layers at room temperature, demonstrating a strong, permanent dipole influenced by external electric fields.
- - They found that for ferroelectric ordering to occur, a monolayer of 2D ice is necessary, with findings supported by both simulations and tests on water's partial pressure and temperature.
- - The unique properties of this 2D ice allow for the development of new nanoelectromechanical devices with memory capabilities, showing significant switching performance and durability without degradation over numerous cycles.
The damage index is a crucial controlling parameter for rock mass strength and deformation in civil, geological and mining engineering projects. In this study, a new method was proposed for computing the damage index of a rock mass based on the field point load strength. This method provides a strength ratio whose numerator is the point load strength (PLS) of splitting along the pre-existing joint and whose denominator is the PLS of intact rock failure.
