Chapter Six - Thermochemical heat storage at high temperature
, 2021 Implementation of cost-effective thermal energy storage systems is one of the signature advantages of concentrating solar power (CSP) plants. Currently these components are based on sensible heat storage in molten salts, but those compounds start to decompose below 600 °C.

Thermochemical generation of hydrogen [PDF]
, 1982 The direct fluid contact heat exchange with H2SO4 at about 330 C prior to high temperature decomposition at about 830 C in the oxygen release step of several thermochemical cycles for splitting water into hydrogen and oxygen provides higher heat transfer

steel research international, EarlyView.This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

The Chemical Record, EarlyView.Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Jasmonates enhance plants tolerance grown in Cd‐contaminated environments: A comprehensive overview
Annals of Applied Biology, EarlyView.Jasmonates (JAs) enhance plant tolerance to cadmium (Cd) stress by activating antioxidant defences but may reduce Cd uptake, limiting their effectiveness for phytoremediation. This review compiles studies that evaluated the effects of JA application on plants grown in Cd‐contaminated environments. Abstract Cadmium (Cd) is a toxic heavy metal and one of
