Erratum: Casting Protocols for the Production of Open Cell Aluminum Foams by the Replication Technique and the Effect on Porosity

A journal reference was corrected in the publication of Casting Protocols for the Production of Open Cell Aluminum Foams by the Replication Technique and the Effect on Porosity. Reference 21 and 22 were originally merged together as one reference. They have been separated into references 21 and 22 in the article. The reference numbers have been updated in the article to reflect this additional reference citation. It has been updated from:

21. LeMay, J.D., Hopper, R.W., Hrubesh, L.W., & Pekala, R.W. Low-Density Microcellular Materials. Materials Research Society Bulletin. 15 (12), 19–20 (1990).Seliger, H., & Deuther U. Die Herstellung von Schaum- und Zellaluminium. Feiburger Forschungshefte. 103–129 (1965).
