Amorphous metals are very thin, of the order of 0.025–0.04 mm. They have the lowest coercivity of all the soft magnetic materials and a higher resistivity than electrical steels, resulting in a material with the lowest core loss (see Table 1). There are a number of issues regarding the ...
The intragap states have been observed (but not commented on) in previous works [25], and treated as VB and CB of the DNC. However, DNC presents little to no cytotoxicity [26] and has been recognized as an outstanding material in photocatalysis along with graphene-based composites [24,27...
In reality, the chemical nature of the metal elements may determine the antiviral properties rather than the morphological characteristics of the nanoparticles. To this end, this review begins with an exhaustive compilation of the antiviral performances of metal nanoparticles and other metallic materials....
(oxidation state of oxygen is -1/3). According to theacidity and alkalinity, whether salt forms with water or not, and the salt content generated can be divided into acid oxide, basic oxide, amphoteric oxide, neutral oxide, complex oxide, etc. Most of metal oxides are basic oxides, but ...
and sense. Changes in cell parameters due to the size-related structural alterations have been observed, for example, in nanoparticles of CuO, ZnO, SnO2, Al2O3, MgO, ZrO2AgO, TiO2, CeO2, etc. As the size decreases in the nanoparticles, an increasing number of surface and interface atoms...
Electrodes chemically modified with molecular active sites are potent catalysts for energy conversion reactions. Such electrodes are typically presumed to operate by the same redox mediation mechanisms as the analogous soluble molecules, with electron tr
The intentional or involuntary incorporation of ENPs into the environment is carried out through different processes. The ENPs are combined with other compounds and release into the atmosphere, settling on the ground due to the water cycle or other atmospheric phenomena. In the case of aquatic ...
Manganese oxidation as the origin of the anomalous capacity of Mn-containing Li-excess cathode materials. Nat. Energy 4, 639–646 (2019). Article CAS Google Scholar Li, B. et al. Correlating ligand-to-metal charge transfer with voltage hysteresis in a Li-rich rock-salt compound exhibiting ...
Calculations of binding energy of oxygen in 3 d transition metal oxides were carried out on the basis of an ionic model taking into account the crystal field effects. Good agreement was obtained with experimental data concerning variations of binding energy of bulk oxygen in isovalent series. The...
Properties of a metal change with an increase indeformation temperature. Therefore the metal will react differently to the same manufacturing operation if it is performed under various temperatures and the manufactured part may possess different related properties. In metal forming processes, there are ...
