Front Chem. 2016 Mar 31;4:13. doi: 10.3389/fchem.2016.00013. eCollection 2016.

The present study aimed to investigate the influence of albumin structure and gold speciation on the synthesis of gold nanoparticles (GNPs). The strategy of synthesis was the addition of HAuCl4 solutions at different pH values (3-12) to solutions of...

Opt Lett. 2017 Sep 01;42(17):3419-3422. doi: 10.1364/OL.42.003419.

We report on the experimental observation of an intermodal noise-seeded modulational instability process (MI) taking place in the normal dispersion regime of a few-mode graded-index optical fiber. Strong power dependence of the MI spectra is observed, with a peak...

Spatial structures and dynamics of kinetically constrained models of glasses.

Physical review letters

Phys Rev Lett. 2004 May 07;92(18):185504. doi: 10.1103/PhysRevLett.92.185504. Epub 2004 May 04.

Kob and Andersen's simple lattice models for the dynamics of structural glasses are analyzed. Although the particles have only hard core interactions, the imposed constraint that they cannot move if surrounded by too many others causes slow dynamics. On...

Jet-cooled diode laser spectra of CF3Br in the 9.2 microm region and rovibrational analysis of symmetric CF3 stretching mode.

Pulsed slit-jet high resolution (up to 0.0009 cm(-1) FWHM) infrared diode laser spectra of CF(3)Br, with natural isotopic abundance, were obtained in the region around 9.2 microm at the rotational temperature of about 50 K. In addition, diode laser...

Jamming percolation and glass transitions in lattice models.

Phys Rev Lett. 2006 Jan 27;96(3):035702. doi: 10.1103/PhysRevLett.96.035702. Epub 2006 Jan 27.

A new class of lattice gas models with trivial interactions but constrained dynamics is introduced. These models are proven to exhibit a dynamical glass transition: above a critical density rhoc ergodicity is broken due to the appearance of an...

Opt Express. 2007 Sep 03;15(18):11142-53. doi: 10.1364/oe.15.011142.

In this work we present extensive comparisons between numerical modelling and experimental measurements of the transmission performance of either CSRZ-ASK or CSRZ-DPSK modulation formats for 40-Gb/s WDM ULH systems on UltraWave(TM) fiber spans with all-Raman amplification. We numerically optimised...

Opt Express. 2006 Jan 09;14(1):397-404. doi: 10.1364/opex.14.000397.

We present an experimental analysis of polarization and intermodal noise-seeded parametric amplification, in which dispersion is phase matched by group velocity mismatch between either polarization or spatial modes in birefringent holey fiber with elliptical core composed of a triple...

Neuroradiological and neuropsychological study of a callosal infarct. A case report.

Corpus callosum infarcts are rare, constituing 0.6% of cerebral infarcts, most likely due to a rich blood supply from three main arterial systems. These infarcts may present with slowly evolving and non-localizing neurologic signs and symptoms that suggest the...

Second harmonic generation in multimode graded-index fibers: spatial beam cleaning and multiple harmonic sideband generation.

Opt Express. 2018 Mar 19;26(6):7528-7536. doi: 10.1364/OE.26.007528.

Quantum ghost imaging uses photon pairs produced from parametric downconversion to enable an alternative method of image acquisition. Information from either one of the photons does not yield an image, but an image can be obtained by harnessing the...
