Determination of bud fertility as a simple method for the determination of harvesting volume in Vitis vinifera L. cv Tannat, using two pruning systems

open access: yesOENO One, 2004
Bud fertility was estimated in two commercial vineyards of Vitis vinifera cv. Tannat in the southern region of Uruguay; it was carried out in two periods: 1983-1986 (essay A) and 2001,2002,2003 (essay B).

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Labeling Stem Cells with a Near-Infrared Fluorescent Heptamethine Dye for Noninvasive Optical Tracking

open access: yesCell Transplantation, 2011
Near-infrared (NIR) fluorescent agents hold great promise for noninvasive in vivo imaging. We have recently reported that a NIR fluorescent heptamethine dye, IR-780 iodide, exhibits unique optical properties for biomedical imaging.

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

open access: yesAdvanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.
