“…[47] Microwave heating was based on volumetric heating, and the simultaneous heating of both inside and outside of materials caused more holes on the surface of gelatin obtained by MAE. Volumetric heat occurred because of the internal friction of the polarized dipole molecules, [48,49] thus making materials heated instantaneously. For these reasons, the surface morphology of gelatin extracted by short-term MAE (5-30 min) was not damaged so much.…”

In this study, we investigated the effect of microwave-assisted extraction (MAE) on the yield, structure, and properties of rabbit skin gelatin. Compared to water bath extraction gelatin, short-term (5-30 min) MAE gelatin had better gel properties, which formed gels at a slower rate due to destruction of more hydrogen bonds, but had more powerful triple helix-like structures after a sufficiently long maturity (16-18 h) since more high-molecular-weight subunits were retained. Scanning electron microscope showed that MAE could form numerous holes on the surface of gelatin. This study will be of great significance for high efficiency of gelatin extraction.

“…Recently, perovskites have been extensively studied in applications like solid oxide fuel cells, oxygen-permeable membranes, gas sensors, catalysts, and photocatalytic materials [6][7][8][9]. Perovskite-type metal oxides have the general formula ABO 3 ; if A and/or B sites are substituted with lower valent cations, some oxygen ions are removed from the lattice in order to maintain charge neutrality, thereby giving rise to oxygen non-stoichiometry [10]. Perovskite metal oxides exhibit extremely high selectivity for oxygen due to the existence of oxygen vacancy.…”

Oxy-fuel combustion is one of the proposed technologies with the potential to achieve zero CO 2 emission. La 1−x Ca x Co 1−y Fe y O 3−δ (LCCF) perovskites are promising materials with high selectively for oxygen. In this study, the oxygen non-stoichiometry of perovskites LCCF was investigated by means of iodometric titration. LCCF was prepared using the liquid citrate method, and the phase structures were identified by X-ray diffraction. Fixed-bed experiments were performed to study the oxygen desorption performance of LCCF. The oxygen deficiency of LCCF increased with increasing Ca molar content of A site, but the value of δ of LCCF with increasing Fe molar content in B site is nearly constant. Experimental observation demonstrated that the O 2 release amount of LCCF does not depend on oxygen non-stoichiometry δ generated from A-site doping. At the same time, doping Fe in B site has an obvious impact on the oxygen desorption amount.

“…The objective of this work is to study the double perovskite as an oxygen carrier for CO 2 capture in oxyfuel combustion applications. Our previous studies demonstrated that Ba‐Co‐O based perovskites oxygen carrier have relatively high oxygen desorption performance 23 . In this study, we choose Ba‐Co based double perovskite‐type oxides as the oxygen carrier and study the B′ site doping effect on the oxygen release performance.…”

Summary Novel oxygen‐deficient double‐perovskite type oxide Ba2NixCo2−xO6 was applied to produce O2/CO2 mixed stream gas for oxyfuel combustion application. A series of different Co concentration substituted Ba2NixCo2−xO6 was synthesized by an EDTA‐citrate sol‐gel combustion method. The oxygen carriers, Ba2Ni0.25Co1.75O6, Ba2Ni0.45Co1.55O6, Ba2Ni0.65Co1.35O6 and Ba2Ni0.85Co1.15O6 were c\characterized by scanning electron microscopy and cyclic oxygen adsorption/desorption experiments. The results showed that the capacity of provided O2 was improved by the partial substitution of Ni by Co. In addition, the synthesized perovskites exhibit good regeneration ability. The optimal degree of Co substitution was x = 0.25 for Ba2NixCo2−xO6 with consideration of oxygen desorption ability. Therefore, Ba2Ni0.25Co1.75O6 was selected to examine the influence of the operating parameters on the oxygen release performance. It was found that the desorption temperature and CO2 partial pressure are the two main operating parameters for the oxygen desorption performance. Further, the proposed novel double perovskite Ba2Ni0.25Co1.75O6 provided excellent performance, the O2 production of Ba2Ni0.25Co1.75O6 can still reach 120 mg/g after 10 cycles.
