Compressible Carbon Sponges from Delignified Wood for Fast Cleanup and Enhanced Recovery of Crude Oil Spills by Joule Heat and Photothermal Effect

Advanced Functional Materials, 2020
Fast and efficient cleanup of crude oil spills is still a global challenge because most of the crude oils are highly viscous and lowly fluid. Herein, a kind of polydimethylsiloxane‐decorated wood carbon sponges (PDMS@WCS) with desirable compressibility ...

Oxygenic Enrichment in Hybrid Ruthenium Sulfide Nanoclusters for an Optimized Photothermal Effect.

ACS Applied Materials and Interfaces, 2021
Transition-metal dichalcogenide (TMD)-based nanomaterials have been extensively explored for the photonic therapy. To the best of our knowledge, near-infrared (NIR) light is a requirement for the photothermal therapy (PTT) to achieve the feature of deep ...

Photothermal effect of Au nanoparticles and photothermal inactivation to saccharomycetes cell

Optik, 2020
Abstract Au nanoparticles (Au NPs) absorb light energy and convert it to thermal energy that transfers to environment. The temperature variation of Au NP and environment as well as photothermal conversion efficiency of Au NP are problems concerned by researchers.

Pyrometry using a photothermal effect

Annual Meeting Optical Society of America, 1986
Pyrometry is a widely used nonintrusive technique to measure surface temperature. The signal received by the detector results from both intrinsic emission and ambient radiation reflected from the sample. The first problem is to measure quantitatively the emission only. This being achieved, the problem of the generally unknown emissivity remains.

Photothermal effect in Semiconductors

Physical Review, 1961
When a sample of semiconducting material is illuminated, pairs of excess carriers are generated which diffuse through the material according to the density gradients established. Each pair carries an energy approximately equal to the band gap of the material.

Photothermal Dielectric Effect with Liquid

Japanese Journal of Applied Physics, 1996
A new photothermal technique for measuring the thermal characteristics of a liquid is proposed. This is based on the temperature characteristic of the dielectric constant of light-irradiated liquid. When an alternating temperature change occurs in a liquid material due to the absorption of chopped light, an alternating variation of ...
