Megan‘s most recent paper exploring the phase evolution in sputter deposited Hanyes 242 through in situ TEM observations is now available online! https://doi.org/10.1016/j.scriptamat.2019.07.028 Her work clarifies our hypothesis in her first paper, clearly demonstrating that the equilibrium phase with the HCP-like DOa structure precipitates via continuous ordering much like the metastable phases (e.g. Ni2(Mo,Cr) with […]
Four years of research and interdisciplinary team facilitated through the BP-ICAM has lead to our most recent publication in ACS Energy & Fuels (DOI: 10.1021/acs.energyfuels.9b00386). This paper summarizes the impact of surface passivation on mitigating the deposition of S-containing asphaltenes. The lead author, Pralav Shetty, recently graduated, but he spent several years working with students in […]
Eric Lang, a graduate student in Jean Paul Allain’s research group in NPRE, is the lead author on a new publication entitled “Deciphering the role of second phase precipitates on early-stage surface morphology development of dispersion-strengthened W alloys under low energy He irradiation.” This effort was facilitated through collaboration with our group to process the […]

Megan’s first paper on phase transformations in nanotwinned Ni-Mo-Cr alloys is now available online: https://doi.org/10.1016/j.actamat.2018.07.007. Congratulations, Megan!
Our most recent paper was recently published in Chemistry of Materials. Students Pralav Shetty and Runyu Zhang (Braun group) collaborated to develop scalable, economic and thermally stable inverse opal structures through aluminization of electrodeposited Ni. This work is closely related to our efforts to modify the surface chemistry of structural alloys in the oil and […]

A new paper from Prof. Krogstad and co-authors at Johns Hopkins University was published today in Acta Materialia: https://doi.org/10.1016/j.actamat.2017.10.065. This work complements another recent paper in Science Advances.
In a recent publication, authors Gidong Sim (JHU) and Prof. Jessica Krogstad reported a novel metallic alloy that could be a game changer for next generation microelectromechanical systems (MEMS) based on its exceptional strength and thermal stability. The high density of nanotwins lead to unique interactions between dislocations and other strengthening mechanisms (grain boundary strengthening, solution […]
