Today's guest on Out of Material is researcher, professor and academic Alessandro Mottura. Alessandro specialises in high-temperature metallurgy, with a research focus on single crystal nickel and cobalt superalloys, with work widely published in international journals. Alessandro also leads many of the undergraduate modules in Materials Science and Engineering at the University of Birmingham, has been my personal tutor for the duration of my undergraduate degree, and is the admissions tutor for the department. 

In 1899 Charles H. Duell, then director of the US Patent Office, stated "everything that can be invented has been invented." It is often presumed that the development of metallurgy has largely been completed - Alessandro explains how much we still have to learn. Exploring topics including interplanetary materials science, the power of accident in scientific progress, and the fine balance between perfection and defect introduction in materials processing, Alessandro provides an inspiring, thought-provoking message to the materials scientists of the future. 

Are there materials in the unvierse we cannot yet comprehend or create here on Earth? How can materials analysis progress when operating beyond the scope of human senses? What does the urine of a small red-headed boy have to do with steel?
