Several technologies such as radiography are available for monitoring inside the pipelines. The nondestructive testing (NDT) method is one of the attractive techniques for corrosion detection inside the pipelines. Sometimes, corrosion detection in the pipelines is quite difficult due to lack of access to the outer part. Therefore, backscatter radiography as an NDT inspection technique for in situ detection of corrosion inside the metallic pipelines should be conducted. The Monte Carlo calculation-based simulation was applied to propose a practical design for corrosion detection inside the pipelines without access to back of them. The results showed that the model can detect corrosion location inside a pipe with acceptable accuracy.

In our previous work, the sodiation of melittin, cytochrome c, and ubiquitin in a 1 mM NaOH water/methanol solution was studied by electrospray mass spectrometry. It was suggested that the α-helix is more resistant to sodiation than the β-sheet. In this study, sodiation of enhanced green fluorescent protein (EGFP) composed of a β-barrel was studied in 1% CHCOOH (AcOH) or 1 mM NaOH water/methanol solution by electrospray mass spectrometry.

Magnesium plays an important role in the hardening mechanism of aluminum alloys, but sensitisation-induced intergranular corrosion cracking limits the widespread use of aluminum alloy in equipment. For on-site quantitative assessment of sensitisation in 5-series aluminum alloys, a laser-induced plasma imaging technique is proposed, which evaluates the degree of aluminum alloy sensitisation by obtaining images of the plasma formed by laser ablation of aluminum alloys, and then classifying and quantifying the images using a residual network. Compared to EMAT, XRD, ECT and LIBS techniques, the sample surface only needs to be polished, does not consume chemical reagents and is not affected by the shape and thickness of the workpiece, which provides higher quantitative accuracy, stability and detection efficiency.

The thickness loss caused by corrosion is a vital factor that threatens the health of shell structures. It is significant to perform a non-destructive quantitative evaluation of corrosion-thinning defects in plate structures. Based on the laser ultrasonic guided wavefield scanning technology, this paper proposes an instantaneous wavenumber multi-shot fusion method, which improves the performance of the instantaneous wavenumber imaging method.

Gas evolution reactions in aqueous zinc metal batteries (AZMBs) cause gas accumulation and battery swelling that negatively affect their performance. However, previous work often reported hydrogen as the main, if not the only, gas species evolved in AZMBs; the complexity of gas evolution has been overlooked. For the first time, this work found the CO evolution reaction (CER) in AZMBs, pinpointed its sources, and identified electrolyte modulation strategies.
