MOF-derived hierarchical carbon/ZnO hybrid synergistically boosts photothermal conversion and storage capability of phase change materials

, 2022
The weak photon-capturing ability is a long-standing bottleneck for pristine metal–organic framework (MOF)-based phase change materials (PCMs) in photothermal conversion and latent heat storage applications. Herein, we designed MOF-5-derived hierarchical

Comparison of self-referencing techniques for photothermal detection of trace compounds in water [PDF]

, 2000
Self-referencing techniques are compared for a closed-cell photothermal detector that uses a water meniscus as a pressure sensor. Deflection of the meniscus was measured using an optical fibre Fabry–Perot interferometer.
