Abstract:

There is considerable disagreement in the literature on available oxygen storage capacity, and on the reaction rates associated with the storage process, for three-way automotive catalysts. This paper seeks to address the issue of oxygen storage capacity in a clear and precise manner. The work described involved a detailed investigation of oxygen storage capacity in typical samples of automotive catalysts. The capacity has also been precisely defined and estimates have been made of the specific capacity based on catalyst dimensions. A purpose-built miniature catalyst test rig has been assembled to allow measurement of the capacity and the experimental procedure has been developed to ensure accurate measurement. The measurements from the first series of experiments have been compared with the theoretical calculations and good agreement is seen. A second series of experiments allowed the e ect of temperature on oxygen storage capacity to be investigated. This work shows very clearly the large variation of the capacity with temperature.

Abstract:

Stable oxygen concentration in exhausts is a decisive factor in catalytic purification of the vehicle exhausts. Nanostructured CeO2 is generally added into catalytic coating on a ceramic support to adjust the oxygen concentration because it possesses a unique oxygen storage capacity (OSC). However, a small amount of CeO2 gets insufficient when the oxygen concentration fluctuates in a large range. In the present work, the cordierite-CeO2 composite ceramic with oxygen storage capacity was prepared for a support material of catalytic converters. The oxygen storage-release performance of the ceramics, including temperature of releasing oxygen, adsorption process of oxygen and the oxygen storage, was examined by a temperature-programmed gas chromatography. The composition of the ceramics was analyzed by an X-ray powder diffraction (XRD) and a scanning electron microscope (SEM) to validate the reliability of the ceramic as the support material with OSC. Results show that the ceramics consist of α-cordierite and CeO2 phases, the latter of which is uniformly dispersed throughout the cordierite matrix. The ceramic powder with 10-20wt% of CeO2 possesses the expected oxygen storage capacity. It is suggested that this novel cordierite-CeO2 composite ceramic is helpful of improving the purification effect of vehicle exhausts.

Abstract:

Every day, thousands of patients receive erythrocyte concentrates (ECs). They are indispensable for modern medicine, despite their limited resource. Artificial oxygen carriers (AOCs) represent a promising approach to reduce the need for ECs. One form of AOCs is perfluorodecalin-filled albumin-based nanocapsules. However, these AOCs are not storable and need to be applied directly after production. In this condition, they are not suitable as a medicinal product for practical use yet. Lyophilization (freeze drying) could provide the possibility of durable and applicable nanocapsules. In the present study, a suitable lyophilization process for perfluorodecalin-filled nanocapsules was developed. The nanocapsules were physicochemically characterized regarding capsule size, polydispersity, and oxygen capacity. Even though the perfluorodecalin-filled albumin-based nanocapsules showed a loss in oxygen capacity directly after lyophilization, they still provided a remarkable residual capacity. This capacity did not decline further for over two months of storage. Furthermore, the nanocapsule size remained unaltered for over one year. Therefore, the AOCs were still applicable and functional after long-term storage due to the successful lyophilization.

Abstract:

Abstract Introduction: The goal of a red blood cell (RBC) transfusion is to treat anemia and improve oxygen delivery to tissues (Sharma 2011). RBC metabolic changes during liquid storage increases the affinity of hemoglobin for oxygen by depletion of 2,3-diphosphoglycerate (2,3-DPG). This change reduces the partial pressure of O2 where the oxygen tension of hemoglobin is 50% saturated (p50). Transfusion of stored RBCs manifests immediate deficits in patient 2,3-DPG concentration after surgery with incomplete in vivo restoration 72 hours post-surgery (Scott 2016). This change may bring into question the efficiency of peripheral oxygen unloading of liquid stored RBCs following transfusion. Ex-vivo rejuvenation of allogeneic RBCs increases the levels of ATP and 2,3-DPG and increases the p50 of stored RBCs by right-shifting the Oxyhemoglobin Dissociation Curve (ODC) (Dennis 1979). RBC Oxygen Release Capacity (ORC) is determined by the percent of oxygen removed from hemoglobin across the arterial (100 mmHg O2) - venous (40 mmHg O2) pressure gradient (Li 2016). The objective was to evaluate the changes in 2,3-DPG and p50 during routine blood bank storage for 35 days and the impact on ORC after RBC rejuvenation. Methods: Five (5) units of human whole blood were collected in CPD, processed into leukocyte reduced RBC units and stored in an additive solution (AS-1). Nearly fresh RBC were obtained from a local blood center after days 3 - 6 of storage at 1-6 °C and then stored up to 35 days at 1-6 °C. A ten (10) mL aliquot was withdrawn from each unit on the day of receipt, then on Days 7, 14, 21, 28, and 35. Each aliquot was split equally by volume into Control (untreated) and Rejuvenated Groups (n=5 per group). The Rejuvenated samples (5 mL) were incubated with 0.8 mL rejuvesol™ Solution (Zimmer Biomet) in a dry air blood warmer (Sarstedt SAHARA-III) for one hour at 37 °C. Complete blood counts (CELL-DYN 3700), ODC (TCS Scientific Corp Hemox-Analyzer), and 2,3-DPG (Roche) on perchloric acid extracts were collected. The ORC was calculated from the ODC as previously described (Li 2016). Results: Five (5) units of CPD/AS-1 RBC units were received less than one week post-donation (5.0 ± 1.2 Days). As expected in the Control Group aliquots (n = 5), 2,3-DPG concentration and the p50 value declined significantly (p < 0.001, ANOVA) from Day 7 through Day 35 (Figure 1). Rejuvenated Group aliquots exhibited a significant increase in 2,3-DPG concentration and improved p50 (p < 0.001, t-test) at each storage interval after incubation with rejuvesol Solution compared to untreated Control aliquots (Figure 1). RBC rejuvenation shifted the ODC to the right (Figure 2) and significantly increased the ORC compared to Control aliquots (Figure 3). The ORC of Rejuvenated aliquots did not decline significantly with storage duration (p = 0.11, ANOVA) while Control aliquots were significantly impacted with storage duration (p < 0.001, ANOVA). Conclusion: Reduction in ORC with storage duration of unrejuvenated RBCs suggests impaired oxygen tissue delivery occurs with stored RBCs to the tissue microenvironment. Transfusion practices designed to increase hemoglobin concentration may be less effective with increased RBC age because of reduced oxygen release capacity. These in vitro results confirm previous reports regarding 2,3-DPG changes during storage and treatment with rejuvenation (Valeri 2000). Additional research is proposed to confirm these observations on full RBC units, the clinical impact of reduced oxygen release capacity, and what impact RBCs with a superphysiological ORC have on the tissue microenvironment.

Abstract:

Abstract Hexagonal Y1−xRxMnO3+δ (R: other than Y rare earth elements) oxides have been recently introduced as promising oxygen storage materials that can be utilized in the temperature swing processes for the oxygen separation and air enrichment. In the present work, the average and local structures of Tb- and Ce-substituted Y0.7Tb0.15Ce0.15MnO3+δ and Y0.6Tb0.2Ce0.2MnO3+δ materials were studied, and their oxygen storage-related properties have been evaluated. The fully oxidized samples show the presence of a significant amount of the highly oxygen-loaded the so-called Hex3 phase, attaining an average oxygen content of δ ≈ 0.41 for both compositions. Extensive studies of the temperature swing process conducted in air and N2 over the temperature range of 180–360 °C revealed large and reversible oxygen content changes taking place with only a small temperature differences and the high dependence on the oxygen partial pressure. Significant for practical performance, the highest reported for this class of compounds, oxygen storage capacity of 1900 μmol O g−1 in air was obtained for the optimized materials and swing process. In the combined temperature–oxygen partial pressure swing process, the oxygen storage capacity of 1200 μmol O g−1 was achieved.

Abstract:

We investigated the gas storage capacity of thermally carbonized and chemically activated Phyllostachys bambusoides (PB), which is a nature-derived green carbon with an organic porous structure. Samples were thermally treated at 900 °C for 24 h, and then were chemically activated with different amounts of KOH. The pore distribution, surface area, and H2 storage capacity were measured by N2 and H2 gas sorption, up to 847 mmHg (1.13 bar) at 77 K. The CO2 storage capacity was measured up to 847 mmHg (1.13 bar) at 298 K. The maximum gas storage was shown in the sample activated with 6 times gravimetric ratio of chemical agent. It reached 1.86 wt% for H2 and 3.44 mmol/g for CO2. We used multilateral analysis methods (XRD, XPS, Raman spectroscopy, and scanning electron microscope) to identify the factors influencing gas sorption. We found that the amount of oxygen groups influence the enhancement of gas storage capacity. Moreover, the results showed that PB-based porous activated carbon has the potential to be used as a multirole gas storage material.

Abstract:

One of the methods for the reduction of harmful emissions from diesel engines such as hydrocarbon, soot and NOx is the use of fuel born catalyst Cerium oxide. The oxygen storage capacity of Cerium oxide can be improved by coating it with metal such as Zirconium. Zr – Ce-O nanoparticles were synthesized by Co-precipitation method in the present work. Dynamic Light scattering, XRD pattern and UV-Visible spectroscopy were used for characterization of the prepared samples. Thermo gravimetric studies were conducted to investigate the thermal decomposition of Zr-Ce-O nanoparticles. The oxygen storage capacity of Zr-Ce-O nanoparticles was analyzed using TPR analysis.

Abstract:

CeO2 is an important rare earth (RE) oxide and has served as a typical oxygen storage material in practical applications. In the present study, the oxygen storage capacity (OSC) of CeO2 was enhanced by doping with other rare earth ions (RE, RE = Yb, Y, Sm and La). A series of Undoped and RE–doped CeO2 with different doping levels were synthesized using a solvothermal method following a subsequent calcination process, in which just Ce(NO3)3∙6H2O, RE(NO3)3∙nH2O, ethylene glycol and water were used as raw materials. Surprisingly, the Undoped CeO2 was proved to be a porous material with a multilayered special morphology without any additional templates in this work. The lattice parameters of CeO2 were refined by the least–squares method with highly pure NaCl as the internal standard for peak position calibrations, and the solubility limits of RE ions into CeO2 were determined; the amounts of reducible–reoxidizable Cen+ ions were estimated by fitting the Ce 3d core–levels XPS spectra; the non–stoichiometric oxygen vacancy (VO) defects of CeO2 were analyzed qualitatively and quantitatively by O 1s XPS fitting and Raman scattering; and the OSC was quantified by the amount of H2 consumption per gram of CeO2 based on hydrogen temperature programmed reduction (H2–TPR) measurements. The maximum [OSC] of CeO2 appeared at 5 mol.% Yb–, 4 mol.% Y–, 4 mol.% Sm– and 7 mol.% La–doping with the values of 0.444, 0.387, 0.352 and 0.380 mmol H2/g by an increase of 93.04, 68.26, 53.04 and 65.22%. Moreover, the dominant factor for promoting the OSC of RE–doped CeO2 was analyzed.

Abstract:

In this work, we present results showing modification of the oxygen storage-related properties of perovskite-type oxides based on BaYMn 2 O 5+δ, having A-site layer-type cation order. Y 3+ is the lightest among suitable cations, which allows to obtain such the structural order, and at the same time, it provides the highest theoretical oxygen storage capacity. However, substitution of Y 3+ by Sm 3+ cations may be beneficial, and BaY 0.5 Sm 0.5 Mn 2 O 5+δ material shows enhanced reduction kinetics. Furthermore, partial substitution of Ba 2+ by Sr 2+ increases reversible oxygen storage capacity, but at the same time slows down the reduction speed. In addition, for higher concentration of strontium, it is not possible to obtain single phase materials.
