General properties of the group The most striking similarities shared by the 24 elements in question are that they are all metals and that most of them are hard, strong, and lustrous, have high melting and boiling points, and are good conductors of heat and electricity. The range in these ...

Thus, the use of transition metals as dopants, such as vanadium (V), tungsten (W), iron (Fe), niobium (Nb) and so on, appears as a promising strategy to improve the performance of photocatalysis or chemiresistive sensors [1], [2], [3], [4], [5], [6], [7], [8], [9], ...
a potent force between two electrons. In the case of copper oxide superconductors, the characteristic energy scale of antiferromagnetic interaction is approximately 130 meV[9], which is roughly an order of magnitude higher than the electron-phonon interaction observed in metals. Consequently, compared ...
Similar results were found for the SACs containing the second-row (Ru) and third-row (Pt) transition metals (Fig. 3h, i, respectively), where Ru and Pt atoms were found to be homogeneously dispersed as single atoms on the carbon support. A further advantage of the synthetic strategy ...
Use of mixtures based on Pt and on compounds based on transition metals other than Pt, for enhancing the arc-resistance properties of silicone elastomers The invention concerns the use as additive for improving properties of resistance to arc tracking and arc erosion: of a mixture A, B or C ...
Transition Metal Dichalcogenides (TMDs) refer to a class of compounds that consist of transition metals coordinated in an octahedral arrangement with chalcogen atoms. They are also known as CdI2-structure compounds due to their similarity to the crystal structure of CdI2. ...
For example, the ALD of metal oxides or metals on graphene is made difficult by the chemically inactive nature of the graphene surface25–27. As 2D TMDCs also have a chemically inactive surface, it is reasonable to expect they will exhibit a unique growth behavior during ALD when compared to...
