Hydrocarbon and Fluorocarbon Monitoring by MIS Sensors Using an Ni Catalytic Thermodestructor

Survey of different sensors employed for the power transformer monitoring

“…Where the measured gas is combustible, catalytic sensors are operational [56]. In these sensors, the gas burns and raises the temperature of a platinum coil and, correspondingly, increases its resistance.…”

A theoretical study of cyclopentene (c-C5H8) dehydrogenation to cyclopentadienyl anion (c-C5H5−) on Ni (111)

“…This topic has special interest in heterogeneous catalysts for naphtha reforming [10]. A number of experimental and theoretical studies have been considered to elucidate the structure and chemistry of such molecules on Ni and other transition metal surfaces [11][12][13][14][15][16][17][18][19][20][21].…”

Hydrogen sensors with double dipole layers using a Pd-mixture-Pd triple-layer sensing structure

“…A number of palladium-and platinum-based hydrogen sensors have been demonstrated. Among them, metal-semiconductor (MS) Schottky diodes [7][8][9][10][11][12][13] and metal-insulator-semiconductor (MIS) [14][15][16][17][18] diodes are the promising devices for detecting hydrogen-containing moieties. Commonly accepted sensing sequences for these kinds of hydrogen sensors are as: the hydrogen molecules are adsorbed and dissociated at a Pd (or Pt) surface, followed by rapid diffusion of H atoms to the Pd-semiconductor (or Pd-insulator) interface where the dipole layer is formed to result in the lowering of Schottky barrier height and the increase of a sensing current.…”
