Half-Bridge Silicon Strain Gauges with Arc-Shaped Piezoresistors

open access: yesSensors, 2023
Half-bridge silicon strain gauges are widely used in the fabrication of diaphragm-type high-pressure sensors, but in some applications, they suffer from low output sensitivity because of mounting position constraints.

Hydrogen Clathrates: Next Generation Hydrogen Storage Materials

open access: yesEnergy Storage Materials, 2021
Abstract Extensive research has been carried on the molecular adsorption in high surface area materials such as carbonaceous materials and MOFs as well as atomic bonded hydrogen in metals and alloys. Clathrates stand among the ones to be recently suggested for hydrogen storage. Although, the simulations predict lower capacity than the expected by the
