Rotational energy has been a key element in many domestic and industrial areas from wristwatches to offshore wind turbines. It utilized on large scale megawatt-scale hydraulic power generators kilowatt-scale vehicles rotating machines, watt-scale hand-held tools, milliwatt (microwatt) rotational harvesters. The scope of this review is microwatt-level harvesters (millimeter centimeter size) that...

Full-spectrum ranging from sub-6 GHz to THz and visible light will be exploited in 6G order reach unprecedented key-performance-indicators. However, an extraordinary amount of energy consumed by network infrastructure, while functions massively deployed Internet Everything (IoE) devices are limited embedded batteries. Therefore, self-sustainable (ESS) is proposed this article. First all, it may...

We propose a hybrid approach which employs the dynamical mean field theory (DMFT) self-energy for correlated, typically rather localized orbitals and conventional density functional (DFT) exchange-correlation potential less orbitals. implement this (plus charge density) self-consistent $\mathrm{DFT}+\mathrm{DMFT}$ scheme in basis of maximally Wannier using wien2k, wien2wannier, DMFT impurity so...
