Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...

Thermal NDE of thick GRP panels by means of a Pulse Modulated Lock-In Thermography technique
This work describes the development and implementation of an infrared thermal NDE procedure for the evaluation of subsurface defects. The approach is called Pulse-Modulated Lock-In Thermography (PMLT) and is based on the analysis of the frequency ...

Defect Visualization and Effective Data Compression Techniques for Infrared Pulsed Thermography
In Pulsed thermography experiment depending on the camera specification one deal with a 3D data of large size, extracting the relevant information from the experimental data can be quite tedious. For doing any inferential and quantitative analysis from the thermography data in a semi-automated and automated manner it is necessary that the dimension of ...

Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Maternal status, sex, and species influence emotional responses to predator exposure. Mothers show stronger physiological responses, while males and non‐mothers show stronger behavioral responses. Long‐tailed macaques show initially stronger physiological and behavioral responses. Vocal behavior, however, did not differ across groups.

Recent advances in boosting interfacial bubble dynamics with external fields
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...
