Brunello GF, Epting WK, de Silva J, Salvador PA, Litster S, Finklea HO, Lee YL, Gerdes KR, Mebane DS.
PMID: 28890971
Phys Chem Chem Phys. 2017 Sep 27;19(37):25334-25345. doi: 10.1039/c7cp04533f.

It is broadly understood that strontium-doped lanthanum manganate (LSM) cathodes for solid oxide fuel cells (SOFCs) have two pathways for the reduction of oxygen: a surface-mediated pathway culminating in oxygen incorporation into the electrolyte at the triple-phase boundary (TPB),...

Tuning the thermoelectric properties of a single-molecule junction by mechanical stretching.

Physical chemistry chemical physics : PCCP

Torres A, Pontes RB, da Silva AJ, Fazzio A.
PMID: 25612893
Phys Chem Chem Phys. 2015 Feb 21;17(7):5386-92. doi: 10.1039/c4cp04635h.

We theoretically investigate, as a function of the stretching, the behaviour of the thermoelectric properties - the Seebeck coefficient (S), the electronic heat conductance (κel) and the figure of merit (ZT) - of a molecule-based junction composed of a...

Appl Radiat Isot. 2016 Mar;109:389-392. doi: 10.1016/j.apradiso.2015.12.056. Epub 2015 Dec 29.

(123)I is widely used for radiodiagnostic procedures. It is produced by reaction of (124)Xe (p,2n) (123)Cs →(123)Xe →(123)I in cyclotrons. (121)Te and (125)I appear in a photon energy spectrum as impurities. An activity of (121)Te was calibrated absolutely by...

Rev Port Pneumol. 2010 May-Jun;16(3):463-70. doi: 10.1016/S0873-2159(15)30042-8.

UNLABELLED: Asthma is a chronic illness of the airways that can reduce respiratory muscle strength due to the resulting hyperinflation or treatment with corticosteroids. One of the ways to evaluate this respiratory muscular weakness is the Maximal Inspiratory Pressure...

Kinetic roughening model with opposite Kardar-Parisi-Zhang nonlinearities.

Physical review. E, Statistical, nonlinear, and soft matter physics

da Silva TJ, Moreira JG.
PMID: 11308856
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Apr;63(4):041601. doi: 10.1103/PhysRevE.63.041601. Epub 2001 Mar 20.

We introduce a model that simulates a kinetic roughening process with two kinds of particle: one follows ballistic deposition (BD) kinetics and the other restricted solid-on-solid Kim-Kosterlitz (KK) kinetics. Both of these kinetics are in the universality class of...

Growth model with restricted surface relaxation.

Physical review. E, Statistical, nonlinear, and soft matter physics

da Silva TJ, Moreira JG.
PMID: 12513294
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Dec;66(6):061604. doi: 10.1103/PhysRevE.66.061604. Epub 2002 Dec 16.

We simulate a growth model with restricted surface relaxation process in d=1 and d=2, where d is the dimensionality of a flat substrate. In this model, each particle can relax on the surface to a local minimum, as the...

Worst case uncertainty estimates for routine instrumental analysis.

The Analyst

da Silva RJ, Santos JR, Camões MF.
PMID: 12173657
Analyst. 2002 Jul;127(7):957-63. doi: 10.1039/b201362m.

A methodology for the worst case measurement uncertainty estimation for analytical methods which include an instrumental quantification step, adequate for routine determinations, is presented. Although the methodology presented should be based on a careful evaluation of the analytical method,...

Efficiency calibration curves for germanium detectors are usually established by using a large number of standard gamma-ray sources of specific radionuclides, that decay with few gamma-rays, or radionuclides with complex decay schemes, such as 133Ba or 152Eu. But these...

Synchrotron x-ray scattering studies of water intercalation in a layered synthetic silicate.
