the kinetic energy density t(r) expressed in terms of its quantal source, the single﹑article density matrix: tA(r), the integrand of the kinetic energy expectation value; tB(r), the trace of the kinetic energy
With the advent of high-temperature, high-current-density superconductors,1,2 one can store electrical energy in superconducting magnets at higher densities, in terms of required mass or volume, than is possible for currently-available electrical-energy storage systems. High densities are especially im...

Accordingly, it is highly essential for high-energy-density LMAs or Li-M alloy anodes with adjustable thickness, well-guided Li deposition behaviors, and optimized electrochemical performance. In terms of Li-M alloys, the Zn equips with unique traits, such as chemical stability in the ambient ...

Owing to their excellent discharged energy density over a broad temperature range, polymer nanocomposites offer immense potential as dielectric materials in advanced electrical and electronic systems, such as intelligent electric vehicles, smart grids an
celestial and Carrollian holography. The latter exploits the Carroll structure at null infinity while the former takes advantage of powerful toolkit of conformal field theory. The vast majority of these developments have taken place in the last ten years and gave rise to research lines currently und...
(BCO). Lindman et al. suggest, on the basis of density functional theory (DFT) calculations of undoped compositions, that this is a result of preferential segregation of protons to the grain boundaries of BZO, which is then reflected in a higher space-charge potential.71In Y-doped BZO, an...
Remarkably, the origin of the metamaterials is related to the electromagnetic field [45]. Permittivity and permeability in the electromagnetic field are similar to the bulk modulus and density in the acoustic field. This similarity and the focus on the fundamental principles of wave propagation have...
