Non-Destructive Metallic Materials Testing—Recent Research and Future Perspectives

Review of Electromagnetic-Based Crack Sensors for Metallic Materials (Recent Research and Future Perspectives)

Evaluation and non-destructive identification of stress-induced cracks or failures in metals is a vital problem in many sensitive environments, including transportation (steel railway tracks, bridges, car wheels, etc.), power plants (steam generator tubing, etc.) and aerospace transportation (landing gear, aircraft fuselages, etc.). There are many traditional non-destructive detection and evalu...

Higher order based image deconvolution in electromagnetic non destructive evaluation of metallic materials

We present a non-destructive magnetic imaging technique developed for the evaluation of hot-rolled stainless steel. Starting from measurements of magnetic field carried out by means of a Hall probe array, magnetic images of sample surfaces are attained. In order to enhance the signal to noise ratio and to detect defects, we have implemented some image processing protocols. In particular we repo...

Sustainable Non-Metallic Building Materials

Buildings are the largest energy consumers and greenhouse gases emitters, both in the developed and developing countries. In continental Europe, the energy use in buildings alone is responsible for up to 50% of carbon dioxide emission. Urgent changes are, therefore, required relating to energy saving, emissions control, production and application of materials, use of renewable resources, and to...

Acetylcholine: future research and perspectives.

Ever since the initial description of chemical transmission in the early part of the 20th century and the identification of acetylcholine (ACh) as the first such transmitter, interests grew to define the multiple facets of its functions. This multitude is only partially covered here, but even in the areas preselected for this special issue, research on the cholinergic system is still thriving. ...
