“…[1,2] In particular, highfrequency alternate current (AC) filtering and high power pulses are considered as promising applications. [3,4] Such SCs need to exhibit low resistance to enable high current densities, efficient ion diffusion for utilization of the active materials at high charge/discharge rates, and low dimensions suitable for integration in microelectronic devices. [5][6][7] These challenges have been tackled by different strategies.…”

Supercapacitors operating at high frequencies while exhibiting high capacitance have been challenging to fabricate due to high resistance and constrained ion diffusion in the active layers. To overcome these limitations, thin layers of pseudocapacitive materials with high theoretical capacitance can be used. Still, construction of such electrodes exhibiting effective ion diffusion, sufficient electrochemically‐active surface area, and high conductivity has encountered significant difficulties. Here, we integrated nickel atoms into a ruthenium layer through a simple electrochemical deposition method, producing a thin electrode comprising hexagonal nickel ruthenium (NiRu) nanodendrites. Further oxidation of the NiRu alloy generated a thin surface layer of pseudocapacitive RuO2 exhibiting significant areal capacitance. A symmetric device from two NiRu/RuO2 electrodes displayed an energy density of 0.714 μWh cm−2 with a remarkable power density of 1500 mW cm−2, ∼250 W cm−3 for a full device. The NiRu/RuO2 supercapacitor outperforms commercial capacitors in both energy and power densities and may replace bulky capacitors in microelectronic devices.

“…When metallic or carbon arcs are produced, a triggering method for generation, such as a trigger pin, evaporation of metals is always needed [4]. No triggering system is desirable for the plasma production for the simple construction of the plasma sources.…”

The recent trend of the thin film deposition is to prepare ceramics films capable to endure the violent environments such as a corrosive pollutant gases of high temperature. Different kinds of plasma species existing in the same space are advantageous to facilitate a reactive deposition between the gaseous and metallic species. In this work, we study a carbon shunting arc that triggers a gas discharge using a positively-biased electrode. An electrode with a positive voltage of up to 500 V was set nearby the carbon shunting arc source. Nitrogen, methane, or argon was used as an ambient gas. The induced plasma was generated with a time delay from the shunting arc generation moment. The electrical and optical characteristics of the discharge were studied. The onset time of the induced plasma as a function of the ambient gas pressure has a Paschen-like V-shaped characteristic. The generated plasma includes both carbon and gaseous species. At the surface of the positively-biased electrode, both spectrum emissions of carbon and gaseous species are observed, by which the plasma is confirmed to be mixed. This is based on the spectrum observation in addition to the change of the color of the plasma. Shunting arc is an easy production method for generation of a hybrid plasma consisting of metallic (including carbon) and gaseous species. This method is promising to efficiently prepare ceramic films by reactive deposition. This method is simple and both plasma species of metal and gas particles are easily mixed. The carbon shunting arc plasma plays both roles of supplying the carbon species and triggering a gaseous plasma as an induced plasma.

A number of documents have been launched by the European Commission in recent years to increase the amount of renewable energy and reduce the dependence on energy sources (and CRMs) outside of European Union. Solar panels are a great source of renewable energy, and their installed capacity in EU increases each year. The lifetime of a solar panel is approximated to be 20 years, and they are starting to represent a significant group of multimaterial waste to be disposed of in the near future, therefore their recycling aimed at the recovery of valuable and critical materials becomes a crucial part of EU energy transformation. The paper presents the overview on the existing technologies used to recycle end-of-life photovoltaic panels.
