Liu L, Schmid S, Feng Z, Li D, Droubay T, Pauzauskie P, et al.
ACS Nano . 2024 Jun; 18(26):16743-16751. PMID: 38888092
Oriented attachment (OA) occurs when nanoparticles in solution align their crystallographic axes prior to colliding and subsequently fuse into single crystals. Traditional colloidal theories such as DLVO provide a framework...

Wang L, Yang Z, Samarakoon W, Zhou Y, Bowden M, Zhou H, et al.
Nano Lett . 2022 Jun; 22(13):5530-5537. PMID: 35771509
Epitaxial growth is a powerful tool for synthesizing heterostructures and integrating multiple functionalities. However, interfacial mixing can readily occur and significantly modify the properties of layered structures, particularly for those...

Stoerzinger K, Pearce C, Droubay T, Shutthanandan V, Liu Z, Arenholz E, et al.
Langmuir . 2019 Oct; 35(43):13872-13879. PMID: 31589056
The functionality of magnetite, FeO, for catalysis and spintronics applications is dependent on the molar ratio of Fe and Fe and their distribution at the surface. In turn, this depends...

Yang Z, Ong P, He Y, Wang L, Bowden M, Xu W, et al.
Small . 2018 Nov; 14(52):e1803108. PMID: 30397995
Nonuniform and highly localized Li dendrites are known to cause deleterious and, in many cases, catastrophic effects on the performance of rechargeable Li batteries. However, the mechanisms of cathode failures...

Elsaidi S, Sinnwell M, Banerjee D, Devaraj A, Kukkadapu R, Droubay T, et al.
Nano Lett . 2017 Oct; 17(11):6968-6973. PMID: 29048916
The magnetic susceptibility of synthesized magnetite (FeO) microspheres was found to decline after the growth of a metal-organic framework (MOF) shell on the magnetite core. Detailed structural analysis of the...

Varga T, Droubay T, Kovarik L, Nandasiri M, Shutthanandan V, Hu D, et al.
ACS Appl Mater Interfaces . 2017 Jun; 9(26):21879-21890. PMID: 28597657
Polarization-induced weak ferromagnetism (WFM) was demonstrated a few years back in LiNbO-type compounds, MTiO (M = Fe, Mn, Ni). Although the coexistence of ferroelectric polarization and ferromagnetism has been demonstrated...

Droubay T, Chambers S, Joly A, Hess W, Nemeth K, Harkay K, et al.
Phys Rev Lett . 2014 Mar; 112(6):067601. PMID: 24580707
We use angle-resolved photoemission under ultraviolet laser excitation to demonstrate that the electron emission properties of Ag(001) can be markedly enhanced and redirected along the surface normal by the deposition...

Warner C, Chouyyok W, Mackie K, Neiner D, Saraf L, Droubay T, et al.
Langmuir . 2012 Feb; 28(8):3931-7. PMID: 22329500
A method for tuning the analyte affinity of magnetic, inorganic nanostructured sorbents for heavy metal contaminants is described. The manganese-doped iron oxide nanoparticle sorbents have a remarkably high affinity compared...

Warner C, Addleman R, Cinson A, Droubay T, Engelhard M, Nash M, et al.
ChemSusChem . 2010 May; 3(6):749-57. PMID: 20468024
We describe the synthesis and characterization of high-performance, superparamagnetic, iron oxide nanoparticle-based, heavy metal sorbents, which demonstrate excellent affinity for the separation of heavy metals in contaminated water systems (i.e.,...

Lower B, Yongsunthon R, Shi L, Wildling L, Gruber H, Wigginton N, et al.
Appl Environ Microbiol . 2009 Mar; 75(9):2931-5. PMID: 19286784
Antibody recognition force microscopy showed that OmcA and MtrC are expressed on the exterior surface of living Shewanella oneidensis MR-1 cells when Fe(III), including solid-phase hematite (Fe(2)O(3)), was the terminal...
