This communication reports the design and characterization of an air-breathing laminar flow-based microfluidic fuel cell (LFFC). The performance of previous LFFC designs was cathode-limited due to the poor solubility and slow transport of oxygen in aqueous media. Introduction of...

Theory of the incommensurate smectic-A phases in dimesogenic liquid crystals.

The European physical journal. E, Soft matter

Tolédano P, Mettout B, Primak A.
PMID: 15221590
Eur Phys J E Soft Matter. 2004 May;14(1):49-54. doi: 10.1140/epje/i2003-10090-x.

A mechanism assuming a mismatch between the basic smectic periodicity and the amplitude and phase modulations periods of the mass density wave order parameter is proposed, for describing the incommensurate smectic-A structure found in dimesogenic liquid crystals. The different...

BACKGROUND: The purpose of this study was to compare the qualitative and quantitative assessment of perfusion on dual-energy CT (DECT) and planar and single photon emission computed tomography (SPECT)-CT V/Q scanning in patients with chronic thromboembolic pulmonary hypertension (CTEPH).METHODS:...

Extending the concept of weighted CT dose index to elliptical phantoms of various aspect ratios.

Journal of medical imaging (Bellingham, Wash.)

Markovich A, Morgan AG, Dong FF, Primak AN, Li X.
PMID: 28695156
J Med Imaging (Bellingham). 2017 Jul;4(3):031205. doi: 10.1117/1.JMI.4.3.031205. Epub 2017 Jul 05.

The purpose of this study was to extend the concept of weighted CT dose index ([Formula: see text]) to the elliptical phantoms. Based on the published body dimension data, eight body aspect ratios were chosen between 1 (perfectly circular)...

Effect of mosaicity in x-ray studies of critical behavior at the nematic to smectic-A transition.

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

Primak A, Fisch M, Kumar S.
PMID: 12513503
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Nov;66(5):051707. doi: 10.1103/PhysRevE.66.051707. Epub 2002 Nov 19.

Previous studies of critical behavior at the nematic to smectic-A transition by high-resolution x-ray scattering were performed using low magnetic fields of 0.1-0.8 T. In those studies, the transverse resolution was limited by the sample mosaicity which complicated data...

A bond-fluctuation mechanism for stochastic switching in wired molecules.

Science (New York, N.Y.)

Ramachandran GK, Hopson TJ, Rawlett AM, Nagahara LA, Primak A, Lindsay SM.
PMID: 12775835
Science. 2003 May 30;300(5624):1413-6. doi: 10.1126/science.1083825.

Stochastic on-off conductivity switching observed in phenylene-ethynylene oligomers has been explained in terms of changes in ring conformations, or electron localization, or both. We report the observation of stochastic on-off switching in the simplest of wired molecules: octanedithiol, decanedithiol,...

Biaxial nematic phase in bent-core thermotropic mesogens.

Physical review letters

Acharya BR, Primak A, Kumar S.
PMID: 15089553
Phys Rev Lett. 2004 Apr 09;92(14):145506. doi: 10.1103/PhysRevLett.92.145506. Epub 2004 Apr 09.

A biaxial nematic phase had been predicted with D(2h) symmetry, wherein the mesogen's long and short transverse axes are simultaneously aligned along the two orthogonal, primary and secondary directors, n and m, respectively. The unique low-angle x-ray diffraction patterns...

Bias-induced forces in conducting atomic force microscopy and contact charging of organic monolayers.
