Abstract:
... We developed a novel process for fabricating oxygen-rich Zn(O,S) buffer layers by magnetron reactive sputtering with a single oxygen-rich Zn(O,S) target, suitable for industrial all-dry production. Then, we successfully fabricated Cd-free Cu(In,Ga)(S,Se)₂ (CIGSSe) solar cells. By varying the oxygen partial pressure during sputtering from 0 to 20%, we precisely controlled the Zn(O,S) composition, t ...
oxygenpartialpressure, etc ; carbon; iron oxides; oxygen; temperature; thermodynamics; Show all 6 Subjects
Abstract:
... Iron(II) oxide, wüstite, is the iron oxide with the lowest oxygen content. Under ambient conditions it is metastable for two reasons: (1) it undergoes eutectoid decomposition to Fe and Fe₃O₄ below ≈570° C, and (2) depending on temperature, it is thermodynamically stable only for very low oxygen partial pressures, down to below 10⁻²⁰ bar. Hence, for the growth of single crystals from the melt, the ...

Abstract:
... Lungs are the primary interface between the atmosphere and working tissues and act as the primary metabolic machinery of the body. The gas exchange that occurs inside the lungs through alveoli ensures adequate supply of oxygen to the tissues and determines the physical and physiological well beingness of the individuals. Barometric pressure decreases as altitude increases and individuals performin ...

Abstract:
... Protonic solid oxide electrolysis cells (P-SOECs) are one of the most efficient devices for hydrogen production from renewable electricity, but the lack of suitable anodes has led to serious concerns in terms of high anodic overpotentials and low conversion efficiencies. Herein, we demonstrated that both the steam electrolysis performances and efficiency of P-SOECs based on a BaZr₀.₆Ce₀.₂Y₀.₁Yb₀.₁ ...

Abstract:
... Phosphorescence lifetime imaging microscopy (PLIM) using a phosphorescent oxygen probe is an innovative technique for elucidating the behavior of oxygen in living tissues. In this study, we designed and synthesized an Ir(III) complex, PPYDM-BBMD, that exhibits long-lived phosphorescence in the near-infrared region and enables in vivo oxygen imaging in deeper tissues. PPYDM-BBMD has a π-extended li ...

Abstract:
... Oxygen permeable membrane, which has the advantages of high separation selectivity, low energy consumption and simple process in oxygen separation, can be used in the fields of environment and energy, such as pure oxygen preparation, fuel cell, oxygen-enriched combustion and chemical reactor for methane catalytic conversion (e.g. partial oxidation of methane, carbon dioxide reforming with methane) ...
... Hypoxia is a growing concern in aquatic ecosystems. Historically, scientists have used the Pcᵣᵢₜ (the dissolved oxygen level below which an animal can no longer oxyregulate) to infer hypoxia tolerance across species. Here, we tested the hypothesis that the Pcᵣᵢₜ is positively correlated with temperature in the mayfly, Neocloeon triangulifer. Cross-temperature comparisons showed a modest (r = 0.47) ...
... Protoporphyrin IX (PpIX) is a molecule produced in the mitochondria following the administration of its approved precursor, aminolevulinic acid (ALA). Strong light absorber at different wavelengths in the visible range, PpIX is extensively used as a photosensitizer (PS) for Photodynamic Therapy (PDT). PpIX is also an ideal molecular probe for the quantification of the tissue oxygen partial pressur ...

Abstract:
... The room temperature aerosol deposition method is especially promising for the rapid deposition of ceramic thick films, making it interesting for functional components in energy, mobility, and telecommunications applications. Despite this, a number of challenges remain, such as an enhanced electrical conductivity and internal residual stresses in as-deposited films. In this work, a novel technique ...
... Early detection of fetal distress at lambing is essential to reduce mortality. Practicality and accuracy of pulse oximetry to assess oxygenation status in newborn lambs under field conditions was evaluated. Oximetry was compared with blood gas analyses and included assessment of vitality (Apgar test) and vigour (attempt to and successful standing and suckling) of 135 Finnish by Polwarth lambs. Sam ...

Abstract:
... Habitat characteristics determine the presence and distribution of trophic resources shaping seabirds' behavioural responses which may result in physiological consequences. Such physiological consequences in relation to foraging strategies of different life-history stages have been little studied in the wild. Thus, we aim to assess differences in oxidative status, condition (fat stores, i.e. trigl ...

... The objective of this work was to evaluate the physiological responses of juvenile Colossoma macropomum exposed to air for different periods of time. Juveniles weighing 74.78 ± 17.39 g were acclimated for 15 days in 30-L tanks in a recirculating aquaculture system (RAS) at a density of 6 animals/tank. The animals were then fasted for 24 h prior to the air exposure test and six juveniles were captu ...

Abstract:
... We study oxygen vacancies in the tetragonal scheelite phase of bismuth vanadate and identify stable oxygen-deficient structures. Upon subjecting these to variable-cell optimization, we find that oxygen vacancies give rise to significant structural distortions, the degree of which exhibits a vacancy concentration dependence. Furthermore, we show that these distortions give rise to splitting of powd ...
