Design considerations for optimizing the sensitivity of catalytic calorimetric gas sensors: modeling and experimental results

Strategies in developing thin-film sensors for monitoring aseptic food processes: Theoretical considerations and investigations of passivation materials

“…The following theoretical considerations are based on the work of McBride et al [17]. Three different operation modes of the calorimetric H 2 O 2 gas sensors are of interest.…”

“…The calculation is based on the enthalpies of the involved reaction partners. Hereby, the upper limit of the released energy in terms of the temperature rise is derived [17,18]. Subsequently, transport mechanisms such as diffusion and convection are introduced to the calculation model.…”

Nanolink-based thermal devices : integration of ALD tin thin films

“…Van der Pauw [68] showed that, if (i) the contacts are sufficiently small (point-like), (ii) the sample material is homogeneous in thickness, (iii) the contacts are at the circumference of the sample and (iv) the surface is singly connected (does not contain isolated holes), then R 12,34 and R 41,23 are related by 12,34 41,23 exp(…”

“…where F is a function only of the ratio R r = R 12,34 /R 41,23 , satisfying the relation 4.532 ln (2) tR tR…”

“…The porous alumina layer is incorporated to increase the surface area for a higher number of reaction sites and hence more heat generation per unit volume [23]. The heat generated by the combustion process leads to a higher local temperature, which can be detected by a change in the electrical resistance of the heater.…”
