Spark spectrometry has been an established method for the chemical analysis of metallic materials for decades, but still has a critical reputation today. The reason for this is the burn mark that appears on the metal surface during analysis. In the following, we take a closer look at the burn mark and evaluate if visible traces are automatically synonymous with relevant material damage, to answer the question if spark spectrometry can be considered a destructive technique or not.

Bridges are a vital part of our infrastructure, transporting people and goods safely across rivers, valleys and other obstacles. Steel bridges in particular, known for their high load-bearing capacity and durability, play a central role in rail and road transportation. But even these robust structures are not immune to aging or wear and tear - therefore bridge monitoring and maintenance are key.

Biochar could reduce 6% of global CO₂ emissions each year and help turn agricultural waste into valuable raw materials. Professor Mauro Giorcelli of the Politecnico di Torino is exploring its enormous potential, which extends far beyond agricultural use.
