Die Technologie, die am Fraunhofer ISC und der Friedrich-Alexander-Universität entwickelt wurde, zeigt Wasserstoffleckagen durch einen zweistufigen Farbumschlag. Zunächst färbt sich Indikator von violett nach pink bei einer einmaligen Wasserstoffexposition. Bei kontinuierlicher Belastung entfärbt das Pulver, kehrt jedoch in Abwesenheit Wasserstoff den pinken Zustand zurück. Der besteht aus Mikropartikeln, Silica-Nanopartikel, Platin-Nanopartikel Farbstoffe kombinieren, was schnellen...
Induction heating of composite materials is great interest in fields such as controlled polymer curing or degradation, self-healing contactless joining. Ferrimagnetic iron oxide nanoparticle (IONPs) are suitable candidates for a powder additive to provide this indictive functionality, while being low-cost, abundant and well-studied material class. Varying IONP size, morphology doping facilitate fine-tune properties. However, the interactions additives composites often neglected can...
Abstract The detection of toxic gases, such as NH 3 and CO, in the environment is high interest chemical, electronic, automotive industry even small amounts can display a health risk for workers. Sensors real‐time monitoring these gases should be simple, robust, reversible, highly sensitive, inexpensive show fast response. indicator supraparticles presented herein fulfill all requirements. They consist silica nanoparticles, which are assembled to upon spray‐drying. Sensing molecules...
Manipulating ferromagnetic particles using an alternating current (AC) magnetic field is a versatile method for quick, local, and on‐demand heat generation. These can be incorporated into various matrices as heating elements. Their release controlled by adjusting process or material parameters. Herein, proof‐of‐concept flexible polymer composite with customizable magnetically triggered due to prior object identification via fluorescence readout presented. The maximum temperature resulting...
Abstract Carbon foams with and without functional particles were prepared via a simple direct foaming process. The carbon composed of pyrolytic graphite. In the additional particles, latter integrated directly in These catalytic material Saponite induction heat‐able MagSilica ® . characterized including heatability. also successfully tested an heated lab‐scale reactor for case study reaction, ethanol to 1,3‐butadiene.
Abstract Herein, a simple model setup is presented to spray fine liquid droplets containing nanoparticles in an air stream transporting this toward filter material. The are made of silica and tagged with fluorescent dye order render the trace particles easily visible. nanoparticles, first approximation, mimic virus (severe acute respiratory syndrome coronavirus 2) particles. used evaluate different tissues, nowadays, times pandemic, commonly as facemasks, regard their particle retention...
Abstract Ein Indikator auf Suprapartikel‐Basis kann die Anwesenheit von Wasserstoff schnell und kostengünstig erkennbar machen. zweistufiger Farbumschlag zeigt Wasserstoffexposition oder Leckage an. Der Farbindikator wurde in der Zusammenarbeit zwischen dem Fraunhofer‐Institut für Silicatforschung ISC Friedrich‐Alexander‐Universität entwickelt.
In dieser Arbeit konnte ein weiterer und moglicherweise entscheidender Schritt zur Aufklarung des Kriechmechanismus von Gips gemacht darauf aufbauend Kriterien, Wege Strategien aufgezeigt werden, um neue Antikriechmittelsubstanzen zu identifizieren oder vorhandene Kriechmittel gezielt verbessern. Die Gultigkeit Praxistauglichkeit der Kriterien wurde exemplarisch nachgewiesen. Die Basis Untersuchungen gelegt mit Errichtung standardisierter Messaufbauten Verfahren sowie Parameterauswahl fur...
