This study demonstrates that p-type copper-doped lanthanum manganite (LaMnO3) film on aluminum plate substrate is a stable and efficient photo-absorber for hydrogen collection from water. Compared to using photocatalyst powder, thin-film reactor is a convenient method for industrial applications...

Strontium doped lanthanum vanadates, La1−xSrxVO3 (denoted LSV with x = 0, 0.3, 0.5, 0.7 and 1.0), were synthesized using a solid-state reaction method. The oxidation and reduction behaviors of LSV were studied using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Th...

The synthesis of organic–inorganic hybrid polypyrrole (PPy)–lanthanum strontium manganite oxide La0.8Sr0.2MnO3 (LSMO) nanocomposites via chemical oxidative polymerization of pyrrole in presence of LSMO nanoparticles using ferric chloride as oxidant and sodium p-toluene sulfonate as efficient d...

Different zinc (Zn) compounds have unique properties that may influence the amount of Zn absorbed particularly in the presence of phytic acid (PA), a common food component that binds Zn and decreases its bioavailability. In this study, 30-day-old male rats (n = 12/diet group) were fed diets supp...

Copper canisters are planned to be used for final disposal of spent nuclear fuel in Sweden. The canisters will be exposed to slow plastic straining over extensive periods of time. To be able to predict the mechanical properties a range of basic models have previously been developed for copper wi...

In this study, we propose a reaction mechanism for atmospherically sintered copper-phosphorus (Cu–P) alloy electrodes which are expected to replace silver (Ag) electrodes. Structural analysis using transmission electron microscopy (TEM) has revealed that not only copper phosphide (Cu3P) but als...

This work was aimed to explore the relationship between phosphorus and coloring of copper glaze under oxidizing atmosphere. The phase, microstructure and chemical state of the samples were investigated by X-ray diffraction, Scanning electron microscopy, Raman spectroscopy and X-ray photoelectron...

Copper is a common current collector at the anode side in rechargeable batteries. The reactivity of copper is often neglected in battery applications which becomes a problem if the active material is highly reactive as well. Corrosion and compound formation results. Here, we report on the influe...
