Influence of the oxidation step on the behaviour and the performances of an oxygen carrier in fixed bed reactor [PDF]

open access: yesMaterials Research, 2013
Chemical Looping Combustion is a promising technology for clean power generation with integrated CO2 capture. In this process the oxygen required for combustion is provided by a metal oxide.

Effect of Natural Ilmenite on the Solid Biomass Conversion of Inhomogeneous Fuels in Small-Scale Bubbling Fluidized Beds

open access: yesEnergies, 2022
The application of oxygen carriers as alternative bed material in fluidized bed combustion originates from chemical lopping processes. They serve as oxygen transport agents undergoing consecutive redox cycles. Thereby, oxygen carriers can provide surplus

Polymerized liposomes as stable oxygen‐carriers [PDF]

open access: yesFEBS Letters, 1985
We have produced a surrogate erythrocyte (‘hemosomes’) by encapsulating human hemoglobin in polymerized vesicles composed of diacetylenic phospholipids plus or minus cholesterol. Hemoglobin (in the presence or absence of allosteric effectors) was encapsulated by a freeze‐thaw method in large, unilamellar vesicles composed of monomeric lipids ...

Inhibited grain growth to strengthen the redox performance of CuFe2O4 via SiO2 as a support for the chemical looping gasification

open access: yesJournal of Materials Research and Technology, 2022
The inert component is an important part of the oxygen carrier in the chemical looping gasification. In this study, a variety of characterization analyses were conducted to investigate a role of SiO2 in crystal structure, morphology, pore structure ...

Evaluation of CuO/MgAl2O4 in Biomass Chemical Looping Gasification with Oxygen Uncoupling

open access: yesBioResources, 2016
Chemical looping gasification (CLG) is a promising method for the utilization of biomass to produce syngas. However, its realization is largely dependent on the use of an oxygen carrier with a high and stable reactivity in cyclic reduction and oxidation.

Oxygen switches: Refueling for cancer radiotherapy

open access: yesFrontiers in Oncology, 2023
Radiotherapy remains the major therapeutic intervention for tumor patients. However, the hypoxic tumor microenvironment leads to treatment resistance. Recently, a burgeoning number of nano-radiosensitizers designed to increase the oxygen concentration in

Hemoglobin-based oxygen carriers.

open access: yesCritical care (London, England), 2004
Transfusable fluids that may be used as alternatives to red blood cell transfusion offer the promise of preserving tissue perfusion and minimizing hypoxic cellular damage, and this promise may soon be fulfilled. Clinical testing of hemoglobin-based oxygen carriers has faced and met challenges involving molecular design, safety, efficacy, and regulatory
