Thermochemical splitting of CO2 using solution combustion synthesized lanthanum–strontium–manganese perovskites
Takalkar, Gorakshnath; Bhosale, Rahul R.; AlMomani, Fares; Rashid, Suliman; Qiblawey, Hazim; Saleh Saad, Mohammed Ali; Khraisheh, Majeda; Kumar, Gopalakrishnan; Gupta, Ram B.; Shende, Rajesh V. (Peer reviewed; Journal article, 2021-09)Redox reactivity of La(1-x)SrxMnO3 (LSM) perovskites towards a solar thermochemical CO2 splitting (CS) cycle is investigated. The LSM perovskites are synthesized via a solution combustion synthesis (SCS) method using glycine ... -
Transitioning from mesophilic to thermophilic anaerobic digestion at VEAS and the influence of co-digesting primary sludge with potato-stillage
Haualand, Kristine (Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06)Anaerobic digestion (AD) is a microbial degradation process in the absence of oxygen by several complex biological reactions where polymeric organic carbon compounds are transformed into biogas and potential biofertilizer. ... -
Tropical fruit waste-derived mesoporous rock-like Fe2O3/Ccomposite fabricated with amphiphilic surfactant-templating approach showing massive potential for high-tech applications
