Rapid Joule‐Heating‐Induced Non‐Equilibrium Exsolution in Perovskite Oxides for Enhanced Photothermal CO2 Methanation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Rapid Joule heating induces Ni—Fe exsolution from perovskite oxides, forming Ni–Fe/oxide heterointerfaces that enhance photothermal CO2 methanation activity and selectivity. Achieving selective CO2 methanation under photothermal conditions requires catalysts capable of maintaining non‐equilibrium interfacial states that balance reduction and oxidation ...

Tuning Colloidal Stability and Photothermal Conversion Efficiency of Graphite Nanofluids via Anionic‐Nonionic Surfactant Engineering

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

Modeling the solar spectral irradiance

, 2014
Modeling the solar spectral irradiance is necessary for different fields: solar, atmospheric and climate physics. In general, the reconstructions aim to generate the solar spectral irradiance (SSI) at a time where no measurement exists. Therefore, they are based on different solar indicators (named proxies), which have the property to correlate their ...
