Critical behavior in the cubic dimer model at nonzero monomer density (2014)
Journal Article
Sreejith, G., & Powell, S. (2014). Critical behavior in the cubic dimer model at nonzero monomer density. Physical Review B, 89(1), Article 014404. https://doi.org/10.1103/PhysRevB.89.014404

We study critical behavior in the classical cubic dimer model (CDM) in the presence of a finite density of monomers. With attractive interactions between parallel dimers, the monomer-free CDM exhibits an unconventional transition from a Coulomb phase...

Fullerenes as adhesive layers for mechanical peeling of metallic, molecular and polymer thin films (2014)
Journal Article
Wieland, M. B., Slater, A. G., Mangham, B., Champness, N. R., & Beton, P. H. (2014). Fullerenes as adhesive layers for mechanical peeling of metallic, molecular and polymer thin films. Beilstein Journal of Nanotechnology, 5, https://doi.org/10.3762/bjnano.5.46

We show that thin films of C60 with a thickness ranging from 10 to 100 nm can promote adhesion between a Au thin film deposited on mica and a solution-deposited layer of the elastomer polymethyldisolaxane (PDMS). This molecular adhesion facilitates t... Read More about Fullerenes as adhesive layers for mechanical peeling of metallic, molecular and polymer thin films.

Control theory for scanning probe microscopy revisited (2014)
Journal Article
Stirling, J. (2014). Control theory for scanning probe microscopy revisited. Beilstein Journal of Nanotechnology, 5, https://doi.org/10.3762/bjnano.5.38

We derive a theoretical model for studying SPM feedback in the context of control theory. Previous models presented in the literature that apply standard models for proportional-integral-derivative controllers predict a highly unstable feedback envir...

We show that the self-assembly of a diverse collection of building blocks can be understood within a common physical framework. These building blocks, which form periodic honeycomb networks and nonperiodic variants thereof, range in size from atoms t...

PLoS ONE, 9(4), Article e93814. https://doi.org/10.1371/journal.pone.0093814

There is no well-established in vivo marker of nigral degeneration in Parkinson's disease (PD). An ideal imaging marker would directly mirror the loss of substantia nigra dopaminergic neurones, which is most prominent in sub-regions called nigrosomes...
