Dominant stress factors (VPD: atmospheric drought; SM: Soil moisture; T: canopy temperature) for July and August 2018 (a) and 2022 (b) in the SiB4 model. Note that the T stress is only the thermal stress at leaf-level, and VPD stress is only the atmospheric humidity component, without...
the same ∆T, the output of TDNG is related to the thermal conductivity of the materials, the larger thermal conductivity is, the higher the optimal temperature difference is, and the larger the surface charge density is. Through the classical electrodynamics derivation and by ignoring the ...

energy conversion. The photothermoelectric effect refers to the temperature difference (ΔT) formed at different locations of the device after absorption of photon energy, which is then converted into an output voltage through the Seebeck effect3. In the photothermoelectric effect, the output voltage...
The temperature thrust is defined as the difference between the intermediate temperature level T1 and the low temperature level T0, whereas the temperature lift is defined as the difference between the high temperature level T2 and intermediate temperature level T1. ...
