Journal ArticleDOI
Nanometer Resolution Elemental Mapping in Graphene-Based TEM Liquid Cells.
Daniel J. Kelly,Mingwei Zhou,Nick Clark,Matthew J. Hamer,Edward A. Lewis,Alexander M. Rakowski,Sarah J. Haigh,Roman V. Gorbachev +7 more
TL;DR: An order of magnitude improvement in the analytical capabilities compared to previous liquid cell data with 1 nm spatial resolution elemental mapping achievable for liquid encapsulated bimetallic nanoparticles using energy dispersive X-ray spectroscopy (EDXS).
Journal ArticleDOI
Exfoliation of natural van der Waals heterostructures to a single unit cell thickness
Matěj Velický,Peter S. Toth,Alexander M. Rakowski,A. P. Rooney,Aleksey Kozikov,Colin R. Woods,Artem Mishchenko,Laura Fumagalli,Jun Yin,Viktor Zólyomi,Thanasis Georgiou,Sarah J. Haigh,Kostya S. Novoselov,Robert A. W. Dryfe +13 more
TL;DR: Mechanical exfoliation is utilized to produce a two-dimensional form of a mineral franckeite and it is shown that the phase segregation of chemical species into discrete layers at the sub-nanometre scale facilitates franckeites' layered structure and basal cleavage down to a single unit cell thickness.
Journal ArticleDOI
Magnetoresistance of vertical Co-graphene-NiFe junctions controlled by charge transfer and proximity-induced spin splitting in graphene
Pablo Asshoff,J. L. Sambricio,A. P. Rooney,Sergey Slizovskiy,Artem Mishchenko,Alexander M. Rakowski,Ernie W. Hill,Andre K. Geim,Sarah J. Haigh,Vladimir I. Fal'ko,Ivan J. Vera-Marun,Irina V. Grigorieva +11 more
TL;DR: In this paper, the role of few-layer graphene in vertical magnetoresistive devices was investigated and it was shown that it is not a perfect spin filter, but rather a weak spin filter.
Journal ArticleDOI
Direct Observation of Amorphous Precursor Phases in the Nucleation of Protein–Metal–Organic Frameworks
Alana F. Ogata,Alexander M. Rakowski,Brooke P Carpenter,Dmitry A. Fishman,Jovany G. Merham,Paul J. Hurst,Joseph P. Patterson +6 more
TL;DR: The structural evolution of p-MOFs was probed by cryo-transmission electron microscopy, revealing nonclassical pathways via dissolution-recrystallization of highly hydrated amorphous particles and solid-state transformation of a protein-rich amorphus phase.
Journal ArticleDOI
Asymmetric MoS2/Graphene/Metal Sandwiches: Preparation, Characterization, and Application
Peter S. Toth,Matĕj Velický,Mark A. Bissett,Thomas J. A. Slater,Nicky Savjani,Aminu K. Rabiu,Alexander M. Rakowski,Jack R. Brent,Sarah J. Haigh,Paul O'Brien,Robert A. W. Dryfe +10 more
TL;DR: The polarizable organic/water interface is used to construct MoS2 /graphene nanocomposites, and various asymmetrically dual-decorated graphene sandwiches are synthesized, showing excellent hydrogen evolution activity and promising capacitor performance.
