Electrocatalytic oxygen evolution on lithium manganese ferrites in koh medium
(SOCIEDAD CHILENA DE QUÍMICA, 1999)
Synthesis and electrochemical characterization of Si/TiO2/Au composite anode: Efficient oxygen evolution and hydroxyl radicals generation
(2021-02-20)
This paper describes the photoelectrochemical properties of a novel composite anode composed of a 200 nm Au-Sb ohmic contact/300 μm n-Si wafer/20 nm TiO2 /120 nm Au grid. By connecting the Au ohmic contact to the gold grid ...
The formation of ultra-massive carbon-oxygen core white dwarfs and their evolutionary and pulsational properties
(EDP Sciences, 2021-02)
Context. The existence of ultra-massive white dwarf stars, MWD & 1.05 M, has been reported in several studies. These white dwarfs are relevant for the role they play in type Ia supernova explosions, the occurrence of ...
New phase diagrams for dense carbon-oxygen mixtures and white dwarf evolution
(EDP Sciences, 2012-01)
Context. Cool white dwarfs are reliable and independent stellar chronometers. The most common white dwarfs have carbon-oxygen dense cores. Consequently, the cooling ages of very cool white dwarfs sensitively depend on the ...
Novel NiFe/NiFe-LDH composites as competitive catalysts for clean energy purposes
(Elsevier B.V., 2018-07-31)
The electrodeposition of metals generally employs several additives to avoid the formation of undesirable byproducts such as oxides and hydroxides. Although the deposition of metals is still the main goal in the most metals ...
Evolution of the acceptor side of photosystem I: ferredoxin, flavodoxin, and ferredoxin-NADP+ oxidoreductase
(Springer, 2017-12)
The development of oxygenic photosynthesis by primordial cyanobacteria ~2.7 billion years ago led to major changes in the components and organization of photosynthetic electron transport to cope with the challenges of an ...
Evolutionary and pulsational properties of low-mass white dwarf stars with oxygen cores resulting from close binary evolution
(Wiley Blackwell Publishing, Inc, 2004-01)
The present work is designed to explore the evolutionary and pulsational properties of low-mass white dwarfs with carbon/oxygen cores. In particular, we follow the evolution of a 0.33-M⊙ white dwarf remnant in a self-consistent ...
Erythrocytosis: The HIF pathway in control
(Elsevier, 2013)
Organisms living under aerobic conditions need oxygen for the metabolic conversion of nutrition into energy. With the appearance of increasingly complex animals, a specialized transport system (erythrocytes) arose during ...
