A combinatorial characterization scheme for high-throughput investigations of hydrogen storage materials

Abstract

In order to increase measurement throughput, a characterization scheme has been developed that accurately measures the hydrogen storage properties of materials in quantities ranging from 10 ng to 1 g. Initial identification of promising materials is realized by rapidly screening thin-film composition spread and thickness wedge samples using normalized IR emissivity imaging. The hydrogen storage properties of promising samples are confirmed through measurements on single-composition films with high-sensitivity (resolution <0.3 µg) Sievert's-type apparatus. For selected samples, larger quantities of up to ∼100 mg may be prepared and their (de)hydrogenation and micro-structural properties probed via parallel in situ Raman spectroscopy. Final confirmation of the hydrogen storage properties is obtained on ∼1 g powder samples using a combined Raman spectroscopy/Sievert's apparatus.

Mixed oxide growth on combinatorial aluminium–gadolinium alloys — a thermodynamic and first-principles approach

“…The intelligent strategies play a crucial role in technologies ranging from electronics, energy generation and storage, aerospace, medicine, and defence industry [3][4][5]. To achieve these technologies, attention has been given recently to integrate high-throughput first-principles calculations and combinatorial methods to obtain robust, extrapolative tools for gaining insights into structure-property-composition relationships in order to reduce the experimental efforts, time, and cost in the materials discovery process [6][7][8][9][10][11][12][13].…”
