Unburned Carbon in Coal Fly Ash: Exploring Its Potential for Electrochemical Energy Storage in Supercapacitors

Advanced Energy and Sustainability Research, Volume 7, Issue 4, April 2026.
The graphical abstract illustrates a circular waste to value pathway in which coal fly ash is upgraded by isolating unburned carbon and converting it into functional carbon materials. Through carbonization and activation, UC‐derived carbon is transformed into high surface area electrodes for supercapacitors, supporting sustainable energy storage and ...

All optical quartz-enhanced photoacoustic spectroscopy

Acta Physica Sinica, 2013
A trace gas sensor based on all optical quartz-enhanced photoacoustic spectroscopy (QEPAS) is designed and demonstrated. An extra detection light beam is added to the traditional QEPAS setup to convert the amplitude of vibration of the quartz tuning fork, which is proportional to the concentration of the target gas, into the variation of the detection ...

Thermally Gated Dual‐Cascade Nanozyme for Enhanced Mild‐Temperature Photothermal Therapy

Advanced Science, Volume 13, Issue 18, 27 March 2026.
A thermo‐responsive cascade nanozyme (Ru‐GOx‐PNN) synergistically enhances mild photothermal therapy by dual suppression of HSP70 through ROS‐induced lipid peroxidation and ATP depletion. This intelligent system effectively overcomes thermotolerance and amplifies apoptosis, offering a safe and precise strategy for tumor treatment.
