This paper presents an in-situ observation, using neutron imaging, of delayed crack propagation in a high-strength martensitic steel specimen. Delayed cracking is believed to be caused by hydrogen embrittlement occurring due the slow diffusion and accumulation ahead front, causing decreased ductility eventual under constant load. The experiment involved mechanical loading single-edge-notch bend specimen while submerged electrolyte solution (H2O + 3.5% NaCl) cathodic polarization facilitate...
Hyperspectral imaging technology holds great potential for various stages of the mining life cycle, both in active and abandoned mines, from exploration to reclamation. The technology, however, has yet achieve large-scale industrial implementation acceptance. While hyperspectral satellite imagery yields high spectral resolution, a signal-to-noise ratio (SNR), global availability with breakthrough systems like EnMAP, EMIT, GaoFen-5, PRISMA, Tanager-1, limited spatial temporal resolution poses...

Challenge  While recycling and alternative technologies show promise in reducing reliance on primary raw materials, the direct acquisition of essential metals minerals depends extracting new resources. The increasing demand for these resources has significant implications mining, mineral processing, environmental impact. Failing to effectively manage this materials mitigate impact mining could impede global progress towards a cleaner energy future. M4Mining project aims promote...
Hyperspectral imaging data holds great potential for the different stages of mining life cycle in active and post-mining environments. However, technology has yet to reach stage large-scale industrial implementation acceptance. While hyperspectral satellite imagery can achieve high spectral resolution, signal-to-noise ratio (SNR) global availability with break-through systems like EnMAP, EMIT PRISMA, limited spatial resolution poses chal-lenges sectors mining, which require decimetre...
