HaloTag-Based Tools for Live-Cell Imaging and Elucidation of Organellar Redox Biology

Redox homeostasis is a key factor in maintaining cellular function and health. The main determinant of the intracellular redox potential is ubiquitous glutathione (GSH) together with its oxidized dimer (GSSG). Importantly, both redox equilibrium and GSH ho ...

Radiative transfer in luminescent solar concentrators

Sophia Haussener, Sha Li

A luminescent solar concentrator (LSC) offers a viable solution to spectrally convert and concentrate both direct and diffuse sunlight without the need for tracking. Its potential for commercialization is currently limited by the optical performance. A det ...

A 512 x 512 SPAD Image Sensor With Integrated Gating for Widefield FLIM

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Arin Can Ülkü

In this paper, we report on SwissSPAD2, an image sensor with 512 x 512 photon-counting pixels, each comprising a single-photon avalanche diode (SPAD), a 1-b memory, and a gating mechanism capable of turning the SPAD ON and OFF, with a skew of 250 and 344 p ...

Experimental demonstration of the water-holding property of three-dimensional vortices

When injecting dye into a vertical vortex generated by a commercial magnetic stirrer, one finds that dye remains captured around the vortex core over minutes, while it gets mixed with the water outside this region rather rapidly. Thus, considering its hori ...

Lateral Intermolecular Electronic Interactions of Diketopyrrolopyrrole D−π–A Solar Dye Sensitizers Adsorbed on Mesoporous Alumina

Jacques-Edouard Moser, Ulf Anders Hagfeldt, Heewon Bahng

The development of push−pull organic dyes utilizing the donor−(π-conjugated bridge)−acceptor (D−π−A) motif has induced a paradigm shift in the design of efficient nanocrystalline dye-sensitized solar cells (DSSCs), offering control over the aesthetic prope ...

Photoanode/Electrolyte Interface Stability in Aqueous Dye-Sensitized Solar Cells

Michael Graetzel, Guido Viscardi

O'Regan and Gratzel conceived a dye-sensitized solar cell (DSSC), which operates as an artificial photosynthetic system converting solar light into electricity. Nevertheless, it is only recently that the scientific community is focusing on truly aqueous DS ...

Pyridyl- and Picolinic Acid Substituted Zinc(II) Phthalocyanines for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Aravind Kumar Chandiran

A series of tri-tert-butyl zinc(II) phthalocyanines (Pcs) substituted with pyridyl, carboxyl, or picolinic acid anchoring groups on the periphery were prepared. Photovoltaic (PV) studies on these dyes were carried out revealing some interesting features. I ...

Rationalizing Fluorescence Quenching in meso-BODIPY Dyes

Anne-Clémence Corminboeuf, Alberto Fabrizio, Antonio Prlj

meso-Substituted boron-dipyrromethene (BODIPY) dyes are a puzzling class of molecules, which feature contrasting emissive behaviors. The full mechanistic picture for these distinctive properties is still missing. Using static and dynamic excited state comp ...

A study of oligothiophene-acceptor dyes in p-type dye-sensitized solar cells

Ulf Anders Hagfeldt, Lei Zhang, Peng Liu

Two new dyes, E1 and E2, equipped with triphenylamine as the electron donor, oligothiophene as the linker and different electron acceptor groups, have been designed and synthesized as photosensitizers for p-type dye-sensitized solar cells (p-DSCs). A syste ...
