Pyroelectric catalysis

Nano Energy, 2020
Thermal energy derived from temperature fluctuation is one of the most clean natural energy sources in our living environment. Pyroelectric materials that feature for temperature oscillation dependent spontaneous polarization can generate usable electrical power and polarized charge carriers with a high energy conversion efficiency. Thus, pyroelectrics

Pyroelectric-Effect-Assisted Near-Infrared-Driven Photoelectrochemical Biosensor Based on Exponential DNA Amplifier for MicroRNA Detection.

Analytical Chemistry, 2023
Although near-infrared responsive photoelectrochemical (PEC) biosensors have less damage to biological components compared to UV-visible light, they still reveal an inferior response due to the rapid recombination of photogenerated electron-hole. In this

Virus‐Based Pyroelectricity

Advanced Materials, 2023
AbstractThe first observation of heat‐induced electrical potential generation on a virus and its detection through pyroelectricity are presented. Specifically, the authors investigate the pyroelectric properties of the M13 phage, which possesses inherent dipole structures derived from the noncentrosymmetric arrangement of the major coat protein (pVIII)
