PMID: 25987991
Food Sci Nutr. 2015 May;3(3):172-8. doi: 10.1002/fsn3.200. Epub 2015 Jan 22.

This study evaluated the presence of biogenic amines in fermented cow's and goat's milks containing probiotic bacteria, during the first 10 days of chilled storage (4 ± 2°C), when the probiotic strains are most viable. The overall acceptance of...

Three-photon absorption spectra of zinc blende semiconductors: theory and experiment.

Optics letters

Cirloganu CM, Olszak PD, Padilha LA, Webster S, Hagan DJ, Van Stryland EW.
PMID: 19015689
Opt Lett. 2008 Nov 15;33(22):2626-8. doi: 10.1364/ol.33.002626.

We calculate the spectrum of three-photon absorption (3PA) in zinc blende semiconductors using Kane's four-band model. We apply this to ZnSe and measure the 3PA spectrum using femtosecond pulses, obtaining excellent agreement. The spectrum shows the apparent onset of...

To evaluate the incidence of chromosomal aberrations (CA) in peripheral lymphocytes of workers chronically exposed to chemical hazards in a tannery in Franca, São Paulo, Brazil. The exposed group consisted of 10 male workers employed in the same tannery....

Strong two-photon absorption at telecommunications wavelengths in nickel bis(dithiolene) complexes.

Optics letters

PMID: 17308597
Opt Lett. 2007 Mar 15;32(6):671-3. doi: 10.1364/ol.32.000671.

The two-photon absorption spectrum of a nickel bis(dithiolene) complex with extended conjugation and pi-donor substitution is measured by using Z-scan and pump-probe techniques with femtosecond pulses over the spectral range from 1.20 to 1.58 microm, which includes much of...

J Phys Chem A. 2010 Jun 17;114(23):6493-501. doi: 10.1021/jp100963e.

We present an experimental and theoretical investigation of the linear and nonlinear optical properties of a series of acceptor-pi-acceptor symmetrical anionic polymethine dyes with diethylamino-coumarin-dioxaborine terminal groups and different conjugation lengths. Two-photon absorption (2PA) cross sections (delta(2PA)) are enhanced...

Effect of the core/shell interface on auger recombination evaluated by single-quantum-dot spectroscopy.

Nano letters

Park YS, Bae WK, Padilha LA, Pietryga JM, Klimov VI.
PMID: 24397307
Nano Lett. 2014 Feb 12;14(2):396-402. doi: 10.1021/nl403289w. Epub 2014 Jan 15.

Previous single-particle spectroscopic studies of colloidal quantum dots have indicated a significant spread in biexciton lifetimes across an ensemble of nominally identical nanocrystals. It has been speculated that in addition to dot-to-dot variation in physical dimensions, this spread is...

Carrier multiplication in semiconductor nanocrystals: influence of size, shape, and composition.

Accounts of chemical research

Padilha LA, Stewart JT, Sandberg RL, Bae WK, Koh WK, Pietryga JM, Klimov VI.

Acc Chem Res. 2013 Jun 18;46(6):1261-9. doi: 10.1021/ar300228x. Epub 2013 Mar 26.

During carrier multiplication (CM), also known as multiexciton generation (MEG), absorption of a single photon produces multiple electron-hole pairs, or excitons. This process can appreciably increase the efficiency of photoconversion, which is especially beneficial in photocatalysis and photovoltaics. This...
