Role of Binders on the Performance of SnO2‐Based Gas Diffusion Electrodes for Electrochemical CO2 Reduction to Formic Acid

ChemElectroChem, Volume 13, Issue 18, 19 September 2026.
Highlights Ionomers (PIL1‐d, Nafion, Sustainion XA9 & PTFE) have a significant effect on the performance of SnO2‐based gas diffusion electrodes (GDE) for eCO2RR. PIL1‐d effectively stabilizes SnO2 catalyst nanoparticles in spray‐coating inks and enhances eCO2RR towards formic acid.

Toward 100‐Watt‐Level Mid‐Infrared Supercontinuum Light Generation

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
Output power of mid‐infrared supercontinuum (SC) light sources severely prevents their application in long‐distance remote sensing, hyperspectral imaging, directional infrared countermeasures, and so forth. This work demonstrates a 100‐watt‐level all‐fiber mid‐infrared SC light source based on homemade low‐loss (~0.022 dB/m) fluorotellurite glass ...

Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 5, September/October 2026.
ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

Deep Underground Science and Engineering, Volume 5, Issue 3, Page 712-727, September 2026.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an
