Insights into the CO2 Stability-Performance Trade-Off of Antimony-Doped SrFeO3-δ Perovskite Cathode for Solid Oxide Fuel Cells.

Numai utilizatorii înregistrați pot traduce articole

One major challenge for the further development of solid oxide fuel cells is obtaining high-performance cathode materials with sufficient stability against reactions with CO₂ present in the ambient atmosphere. However, the enhanced stability is often achieved by using material systems

Comparative toxicity and tissue distribution of antimony potassium tartrate in rats and mice dosed by drinking water or intraperitoneal injection.

Numai utilizatorii înregistrați pot traduce articole

Antimony potassium tartrate (APT) is a complex salt that until recently was used worldwide as an antischistosomal drug. Treatment was efficacious only if APT was administered intravenously to humans at a near lethal total dose of 36 mg/kg. Because unconfirmed epidemiologic studies suggested there

NTP technical report on the toxicity studies of Toxicity Studies of Antimony Potassium Tartrate (CAS No. 28300-74-5) in F344/N Rats And B6C3F1 Mice (Drinking Water and Intraperitoneal Injection Studies).

Antimony potassium tartrate (APT) is a complex salt that until recently was used worldwide as an anti-schistosomal drug. APT was efficacious in humans only if administered intravenously at a near-lethal total dose of 36 mg/kg. Because unconfirmed epidemiologic studies suggested a possible

Evolution of topological surface states in antimony ultra-thin films.

Numai utilizatorii înregistrați pot traduce articole

Based on an inverted bulk band order, antimony thin films presumably could become topological insulators if quantum confinement effect opens up a gap in the bulk bands. Coupling between topological surface states (TSS) from opposite surfaces, however, tends to degrade or even destroy their novel

Comparative Study of Antimony Doping Effects on the Performance of Solution-Processed ZIO and ZTO Field-Effect Transistors.

Numai utilizatorii înregistrați pot traduce articole

ZnO-based oxide films are emerging as high-performance semiconductors for field-effect transistors (FETs) in optoelectronics. Carrier mobility and stability in these FETs are improved by introducing indium (In) and gallium (Ga) cations, respectively. However, the strong trade-off between the

Seebeck and figure of merit enhancement in nanostructured antimony telluride by antisite defect suppression through sulfur doping.

Numai utilizatorii înregistrați pot traduce articole

Antimony telluride has a low thermoelectric figure of merit (ZT < ∼0.3) because of a low Seebeck coefficient α arising from high degenerate hole concentrations generated by antimony antisite defects. Here, we mitigate this key problem by suppressing antisite defect formation using subatomic percent

CE-ESI-MS metabolic fingerprinting of Leishmania resistance to antimony treatment.

Numai utilizatorii înregistrați pot traduce articole

Metabolomics has become an invaluable tool to unveil biology of pathogens, with immediate application to chemotherapy. It is currently accepted that there is not one single technique capable of obtaining the whole metabolic fingerprint of a biological system either due to their different

Uncovering the Thermo-Kinetic Origins of Phase Ordering in Mixed-Valence Antimony Tetroxide by First-Principles Modeling.

Numai utilizatorii înregistrați pot traduce articole

Phase ordering in the mixed-valence oxide Sb2O4 has been examined by density functional theory (DFT) calculations. We find that the ground-state total energies of the two phases (α and β) are almost degenerate and are highly sensitive to the choice of the approximation to the exchange correlation

Performance characteristics of diffusive gradients in thin films equipped with a binding gel layer containing precipitated ferrihydrite for measuring arsenic(V), selenium(VI), vanadium(V), and antimony(V).

Numai utilizatorii înregistrați pot traduce articole

Measurements at high spatial resolution by DGT (diffusive gradients in thin films) require a binding agent that is homogeneously distributed in the binding layer. Formation of ferrihydrite by in situ precipitation within a hydrogel has been previously shown to meet these requirements for the

Intralesional treatment of cutaneous leishmaniasis with sodium stibogluconate antimony.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Cutaneous leishmaniasis represents a difficult disease to manage in endemic areas. Systemic treatment is hampered by both expense and compliance. Side effects may play a major role in this aspect as well. METHODS The effectiveness of intralesional treatment of leishmaniasis was

Unilateral optic atrophy presumed secondary to schistosomiasis of the optic nerve.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Schistosomiasis, a parasitic disease, is endemic in many parts of the world. Schistosomal eggs may be found in almost any organ or tissue in the body, including the eye. The presence of schistosomal eggs in the eye can produce granuloma formation and inflammatory sequelae. METHODS A

New Sb2Te[object Object],[object Object]Sex Monolayers with High Electron Mobilities and Wide Absorption Range.

Numai utilizatorii înregistrați pot traduce articole

As a traditional thermoelectric material with high thermoelectric performance at room temperature, antimony telluride (Sb₂Te₃) has been widely used in energy applications like power generation and refrigeration. By employing the "atomic transmutation" method, three

Persistent reaction in paucibacillary leprosy: case reports.

Numai utilizatorii înregistrați pot traduce articole

Three patients of histopathologically confirmed borderline-tuberculoid leprosy showing no acid-fast bacilli and with lesions confined to the face, 2 on the cheek and 1 on the forehead, were given multidrug therapy as recommended by the WHO for paucibacillary cases. Within 3 months the lesions showed

A new series of long-range ordered metastable phases in the system M-Sb-Te (M = Ge, Ag).

Numai utilizatorii înregistrați pot traduce articole

New phases with the general formula (MTe)(n)(Sb(2)Te(3))(Sb(2))(4) (n = 0, 1, 2, ; M = Ge, Ag) have been synthesized by quenching stoichiometric melts of the pure elements and subsequent annealing. These phases represent a combination of the well-known homologous series (Sb(2)Te(3))(m)(Sb(2))(k) and

Programmed cell death: cytochemical and X-ray microanalytical characterization of calcium compartments in neuromuscular junctions during the normal breakdown of the intersegmental muscles in the giant silkmoth Antheraea polyphemus.

Calcium stores were cytochemically demonstrated using a combined oxalate-pyroantimonate method in the neuromuscular junctions of the degenerating intersegmental muscles in the giant silkmoth Antheraea polyphemus. The elemental composition of punctate precipitates of the reaction product was
