Towards In-Situ Reservoir Nano-Agents
The advent of atomically accurate sensing and manipulation tools has spurred a widespread interest in nanotechnology with the prospect of re-engineering matter and synthesizing functional systems at the nanoscale. This enabled thinking “outside-the-box” in valuable [...]
Electrospun Nanofiber Layers for Applications in Electrochemical Devices
Low power and/or low energy density belong to main limiting parameters of electrochemical energy storage devices. Increasing of the surface area between an electrolyte and an active electrode material is the way how to improve [...]
Improvement of electric energy density in PVDF terpolymer nanocomposites and blends
Large enhancement in the electric energy density and electric displacement level were found in nanocomposites of poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) (PVDF-TrFE-CFE) relaxor ferroelectric polymer/ZrO2 nanoparticles. Through the interface effect the presence of the nanoparticles (with only 1.6 [...]
Supercapacitor like structure for micro-battery and radiation energy harvesting tile
The usage of hetero-nano-layers to harvest the energy deposited in ionization by the stopping particles and radiation passing through the layers produces very efficient and compact solid-state battery devices. The structure in its simplest forms [...]
