Modulating the Optoelectronic Properties of Tripodal Fluorophores Through Fluorine‐Substituted Peripheral Phenyls

open access: yesChemistry – A European Journal, EarlyView.
C3‐symmetric D‐(π‐D‐π‐A)3 fluorophores featuring central triphenylamine donor, polarizable 2,5‐divinylthiophene linker, and a broad portfolio of fluorine‐based substituents show tunable (non)linear optical properties. ABSTRACT Fourteen novel tripodal fluorophores based on a central triphenylamine donor, electron‐rich, and polarizable divinylthiophene ...

A Versatile Setup for Determining Hydrogen and Oxygen Crossover of Electrolyzer Membranes and MEAs

open access: yesChemie Ingenieur Technik, EarlyView.
Hydrogen and oxygen crossover in PEM electrolyzers affects safety, efficiency and gas purity. We present an experimental setup to quantify crossover through membranes and polymers. It allows in‐situ tests on full cells with MEAs and measures gas permeation in wet or dry ionomers and other polymers.

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Cystatin C‐based eGFR better predicts renal vancomycin clearance than creatinine‐based eGFR in patients with allogeneic stem cell transplantation

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Knowledge of the glomerular filtration rate (GFR) is mandatory when dosing renally eliminated drugs such as vancomycin. In clinical practice, different biomarkers and various equations are used to estimate GFR (eGFR), resulting in varying estimates.
