Concept

GelRed

GelRed is an intercalating nucleic acid stain used in molecular genetics for agarose gel DNA electrophoresis. GelRed structurally consists of two ethidium subunits that are bridged by a linear oxygenated spacer. GelRed is a fluorophore, and its optical properties are essentially identical to those of ethidium bromide. When exposed to ultraviolet light, it fluoresces with an orange color that strongly intensifies after binding to DNA. The substance is marketed as a less toxic and more sensitive alternative to ethidium bromide. GelRed is sold as a solution in anhydrous DMSO or ultrapurified water. GelRed is unable to cross cell membranes.

Synergistic Dual Engineering of NiO x via Ethylenediamine Chelation and γ‐Ray Irradiation for Enhanced Interfacial Transport in Perovskite Solar Cells

This study highlights an interface‐engineering strategy aimed at simultaneously stabilizing nickel oxide (NiO x ) sol–gel solutions and overcoming the intrinsic defects and charge transport limitations of NiO x . NiO x has been widely established as an efficient and stable hole transport layer in inverted perovskite solar cells, but sol–gel‐based NiO x is susceptible to defect formation during thermal annealing, leading to non‐uniform interfacial contact and limited charge extraction efficiency.

Use of Transmission Electron-Microscopy for the Characterization of Rapid Thermally Annealed, Solution-Gel, Lead-Zirconate-Titanate Films

Nava Setter

The microstructure and preferred orientations of rapid thermally annealed Pb(Zr0.53, Ti0.47)O3 films, deposited on Pt/Ti/SiO2/Si electrode/substrates by solution-gel spinning, have been investigated using analytical and high-resolution electron microscopy and X-ray diffraction. The temperature of pyrolysis of the PZT filMS was found to influence the preferred orientation of the film: lower temperatures (350-degrees-C) favored a (111) orientation, whereas higher temperatures (420-degrees-C) favored a (100) o

Web of Science Researcher ID F-4905-2011 Google Scholar page: https://scholar.google.ch/citations?user=O_HhJUEAAAAJ&hl=fr&oi=ao ORCID number is 0000-0001-9222-3866 Anne-Sophie Chauvin studied chemistry and biology at the university Paris V-René Descartes in France where she did a PhD in organic chemistry, working on mimetic complexes of the active site of Nitrile Hydratase, under the supervision of Prof. Jean-Claude Chottard. On 1999 she moved for 20 months to the University of Geneva, for a post-doctoral stay under the supervision of Prof. Alexandre Alexakis, where she focused on the determination of the absolute configuration of chiral alcohols using Organophosphorous Diamine Derivatizing Agents by 31P and 1H NMR Spectroscopy. On 2000 she joined the group of Prof Jean-Claude G. Bünzli and was appointed part-time lecturer in 2001, assuming teaching and research responsibilities. On 2006, she obtained the habilitation to direct research from the University René Descartes (HDR, Paris V, France) and since october 2007 she is Maître d'Enseignement et de Recherche at the EPFL. In 2010, she joigned the Laboratory for Photonics and Interfaces (LPI), headed by Pr. Michaël Graëtzel. Since the end of 2014, with the arrival of Dr Marinella Mazzanti at EPFL, she is back to lanthanide chemistry, dealing with coordination polymers. Her research interests concern supramolecular chemistry with the design of ligands which form water soluble complexes with luminescent lanthanides in view of biological applications. She is also interested in the synthesis of ligands and polymers for the extraction of lanthanide ions with high selectivity, and in the development of invisibke inks. She also developed organic dyes for dyes sensitized solar cells DSSC. She is now focusing on coordination polymers with luminescent properties and catalytic activity. Anne-Sophie Chauvin is involved in the teaching of General and Analytical Chemistry for students enrolled on first year in Pharmacy and Biology (UNIL): ex-cathedra courses (Chimie Générale et analytique I et II, approfondissement en chimie analytique pour pharmaciens) and exercices. She is in charge of practical sessions for students enroled in chemistry, forensic sciences, pharmacy and biology. She is elected at the FSB Faculty Council and was member of the EPFL Assembly (AE) for 6 years, until 2018. She was member of the Management committee of the Cost CM 1006 action entitled Eufen: European F-Element Network. She is Member of the Swiss Chemical Society (SCS) and Fellow of the Royal Society of Chemistry (FRSC).
