The Chemical Looping with Oxygen Uncoupling (CLOU) process is a derivative technology of the Combustion (CLC) for combustion both renewable and non-renewable solid fuels. present work studies CO2 capture efficiency burning coal or biomass using single Cu-based oxygen carrier magnetic properties as an carrier. two different coals three biomasses was performed in 1.5 kWth CLOU continuously operat...

Oxygen Transfer in Oxide Heterostructures In article number 2101867, Zachary Corey, Quanxi Jia, Aiping Chen, and co-workers demonstrate that the growth of an oxide layer a suitable condition can lead to oxygen transfer from substrate film during growth. Such forms conductive surface contributes observed high carrier mobility.

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can be used as gaseous fuels and they may contain different amounts of light hydrocarbons. This paper presents the combustion results obtained with a Cu-...

The Mn-oxide/Nb:SrTiO3 photoelectrode for oxygen evolution reaction was investigated by in situ Mn K-edge XAFS spectroscopy under UV irradiation. The oxidization of the Mn oxide was observed via photoexcited carrier transfer, which results in the positive potential shift of the Mn oxide cocatalyst toward oxygen evolution reaction.

Hemoglobin released into the circulation during hemolysis or therapy with chemically modified hemoglobins, exert oxidative and NO-scavenging toxic effects. Pyridoxalated hemoglobin polyoxyethylene conjugate (PHP) is one of the second-generation hemoglobin-based oxygen carriers (HBOCs). We wanted to investigate the metabolism of PHP with a special focus on its consequences for interpreting hemol...

To analyze the effects of nitrifying bacterial community structure on partial nitrification (PN) characteristics in a PN-immobilized carrier municipal wastewater under low-temperature shock, two carriers with different communities were investigated. The E1-immobilized contained high abundance ammonia-oxidizing bacteria (AOB; 38.59%), and E2-immobilized had low AOB 4.78%. results experiments dis...

We have studied the use of ultrapurified polymerized bovine haemoglobin (HBOC-201) in patients undergoing preoperative haemodilution before liver resection. After autologous blood donation of 1 litre, 12 patients (six males, six females, mean age 59 (35-69) yr) received Ringer's lactate solution 2 litre and, in a random design, 6% hydroxyethyl starch 70,000/0.5 (HES) 3 ml kg-1 or HBOC-201 0.4 g...

BACKGROUND To date, there is no safe and effective hemoglobin-based oxygen carrier (HBOC) to substitute for erythrocyte transfusion. It is uncertain whether a deficiency of endothelial nitric oxide bioavailability (endothelial dysfunction) prevents or augments HBOC-induced vasoconstriction. METHODS Hemodynamic effects of infusion of PolyHeme (1.08 g hemoglobin/kg; Northfield Laboratories, Eva...

Substances such as hemoglobin that interfere with analytical processes are recognized as a frequent source of error in laboratory medicine. Standard guidelines for assessment of test interferences assume that interference effects are not related to the concentration of the analyte being measured. However, previous investigations have demonstrated that interference effects can be markedly differ...

phylaxis. Conspicuous by its absence is any report of such devices precipitating an embolic event during general surgery. We cannot establish causality. It is possible that the embolism would have occurred irrespective of the placement of the sequential devices because of the presence of multiple risk factors in our patient, including age, obesity, malignancy, estrogen replacement hormones, and...
