The effect of Mo and Ge reactive elements on high-temperature oxidation of higher manganese silicide
Shyikira, Antoine de Padoue; Akhtar, Naureen; Skomedal, Gunstein; Middleton, Peter Hugh (Peer reviewed; Journal article, 2021)Higher manganese silicide (HMS) alloys (Mnx-αMoαSiy-βGeβ (x = 0.99–1.011, α = 0.005–0.02, y = 1.75, β = 0.005–0.01)) were studied to elucidate the effect of Mo and Ge pertaining to oxidation. Oxidation experiments were ... -

Methods for enhancing the thermal durability of high-temperature thermoelectric materials
Skomedal, Gunstein; Kristiansen, Nils R.; Engvoll, Marianne; Middleton, Hugh (Journal article; Peer reviewed, 2013)Thermoelectric materials, for example skutterudites and magnesium silicides, are being investigated as promising materials for medium-to-high-temperature waste heat recovery in transport and in industry. A crucial aspect ... -
Performance of a thermoelectric module based on n-type (La0.12Sr0.88)0.95TiO3-δ and p-type Ca3Co4-xO9+δ
Kanas, Nikola; Skomedal, Gunstein; Desissa, Temesgen D.; Feldhoff, Armin; Grande, Tor; Wiik, Kjell; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2020)Here, we present the performance of a thermoelectric (TE) module consisting of n-type (La0.12Sr0.88)0.95TiO3 and p-type Ca3Co4-xO9+δ materials. The main challenge in this investigation was operation of TE module in different ... -
Thermal durability of novel thermoelectric materials for waste heat recovery
Skomedal, Gunstein (Doctoral dissertations at University of Agder;, Doctoral thesis, 2016)Thermoelectric Generators (TEG) are a potential technology for waste heat recovery. At their hearts, thermoelectric materials convert a heat flux into electric current. By placing TEGs on the surface of a waste heat source, ...
