Electron-stimulated purification of platinum nanostructures grown via focused electron beam induced deposition.

Beilstein journal of nanotechnology

Lewis BB, Stanford MG, Fowlkes JD, Lester K, Plank H, Rack PD.
PMID: 25977862
Beilstein J Nanotechnol. 2015 Apr 08;6:907-18. doi: 10.3762/bjnano.6.94. eCollection 2015.

Platinum-carbon nanostructures deposited via electron beam induced deposition from MeCpPt(IV)Me3 are purified during a post-deposition electron exposure treatment in a localized oxygen ambient at room temperature. Time-dependent studies demonstrate that the process occurs from the top-down. Electron beam energy...

Electron nanoprobe induced oxidation: a simulation of direct-write purification.

Physical chemistry chemical physics : PCCP

Fowlkes JD, Geier B, Lewis BB, Rack PD, Stanford MG, Winkler R, Plank H.
PMID: 26058775
Phys Chem Chem Phys. 2015 Jul 28;17(28):18294-304. doi: 10.1039/c5cp01196e.

Electron beam direct-write has recently taken a large step forward with the advent of methods to purify deposits. This development has opened the door for future direct-write device prototyping and editing. In one such approach, an additional beam scanning...

Cognitive Enhancement Therapy Improves Resting-State Functional Connectivity in Early Course Schizophrenia.

Journal of the Society for Social Work and Research

Eack SM, Newhill CE, Keshavan MS.
PMID: 27713804
J Soc Social Work Res. 2016;7(2):211-230. doi: 10.1086/686538. Epub 2016 May 02.

OBJECTIVE: Cognitive remediation is emerging as an effective psychosocial intervention for addressing untreated cognitive and functional impairments in persons with schizophrenia, and might achieve its benefits through neuroplastic changes in brain connectivity. This study seeks to examine the effects...

A Monte Carlo simulation is developed to model the physical sputtering of aluminum and tungsten emulating nanoscale focused helium and neon ion beam etching from the gas field ion microscope. Neon beams with different beam energies (0.5-30 keV) and...

Simple analytical particle and kinetic energy densities for a dilute fermionic gas in a d-dimensional harmonic trap.

Physical review letters

Brack M, van Zyl BP.
PMID: 11290196
Phys Rev Lett. 2001 Feb 19;86(8):1574-7. doi: 10.1103/PhysRevLett.86.1574.

We derive simple analytical expressions for the particle density rho(r) and the kinetic energy density tau(r) for a system of noninteracting fermions in a d-dimensional isotropic harmonic oscillator potential. We test the Thomas-Fermi (TF, or local-density) approximation for the...

Ordovician and Silurian acritarch assemblages from the west Leinster and Slievenamon areas of southeast Ireland.
