Summary: Joule heating in micromechanical resonators has potential for various applications, but its effects on resonator performance are not fully understood. We established a theoretical model and conducted experiments to study this effect. The results showed that Joule heating can enhance the dynamic range and signal-to-noise ratio of the resonator. Furthermore, the frequency stability of piezoresistive oscillators improved with increasing drain current.

Summary: The effect of Joule heating generated by pulsed electric fields on cell electroporation was investigated. It was found that considering Joule heating lowered the electroporation threshold, increased plasma membrane conductivity and pore number. Furthermore, the effect of pulse burst repetition frequency on cell electroporation was found to be non-monotonic.

Summary: This paper investigates the influence of Joule heat induced by electric current on thermal stress and structural failure by using complex variable methods to obtain the thermoelastic fields around an elliptic cavity. The temperature dependency of thermoelastic coefficients is considered, and an analytical method is introduced to verify the results. It is found that under the temperature-dependent assumption, the stress intensity factor increases to a greater extent when the elliptic cavity is reduced to a linear crack.

Summary: Microwave heating promoted by supported platinum nanoparticles on metal oxide substrates is influenced by the transparency of the substrate, with low relative permittivities and conductivities leading to considerable heating. The size and loading of the platinum nanoparticles, as well as the conductivity of the supported metal and the frequency of the microwaves, all play significant roles in the effectiveness of microwave heating. The synergy between metal nanoparticles and metal oxide support results in targeted microwave heating of the supported metal catalyst.
