The purpose of this study was to select an
alloy with a low driving force for nucleation
for a more in-depth study of the nucleation
of γ’-precipitates. To do this, three Ni-Cr-Al
alloys were chosen close to the solvus line
of a Ni-Cr-Al phase diagram, ensuring low
supersaturation and therefore...
We report on a diffusive analysis of the motion of flagellate protozoa species. These parasites are the etiological agents of neglected tropical diseases: leishmaniasis caused by Leishmania amazonensis and Leishmania braziliensis, African sleeping sickness caused by Trypanosoma brucei, and Chagas disease caused by Trypanosoma cruzi. By tracking the positions of...
Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...
Assembly of the large and small subunits of the <em>E. coli</em> ribosome is a complicated process that involves transcription, processing, and modifying of the ribosomal RNA, the binding of ribosomal proteins, and the folding of the particles into complex structures. A number of ribosome assembly factors, including maturation factors, GTPases,...
Artificial spin ice lattices have emerged as model systems for studying magnetic frustration in recent years. Most work to date has looked at periodic artificial spin ice lattices. In this paper, we observe frustration effects in quasicrystal artificial spin ice lattices that lack translational symmetry and contain vertices with different...
This short talk was a part of a panel, "Digital Literacy in the Classroom," organized by Ann Hanlon and Abigail Nye (University of Wisconsin-Milwaukee), and which included Harriett Green (University of Illinois Urbana Champaign), and myself, at the 2016 DLF Forum in Milwaukee, WI, on November 8, 2016.
Nuclear magnetic resonance (NMR) measurements have been performed on the heavily Cu-doped ($x = 0.13$, 0.18, 0.24, 0.39, 0.48), and underdoped (x = 0.01 and 0.012) \NaFeCuAs~ single crystals, to reveal the nature of the magnetism, and to investigate how the electronic and magnetic properties of the system evolves with...
