“…The latter effect also occurs due to the increase in activation temperature, as mentioned above in the discussion of the BET and Raman analyses. The capacitance values of the ACPs obtained from cellulose fibers from which lignin, hemicellulose, ash, and other substances were removed to improve the electrode performance are comparable to those of the rice-husk derived activated carbon electrodes with the addition of a binder and high-conductive materials in other recent studies [ 43 , 44 , 45 , 46 , 47 ]. Thus, ACPs obtained from rice husk-extracted cellulose papers could be created as high-performance free-standing electrodes without the addition of a binder and conductive materials.…”

For the preparation of activated carbon papers (APCs) as supercapacitor electrodes, impurity substances were removed from rice husks, before carbonization and various activation temperature treatments, to optimize electro chemical efficiency. The porosities and electrochemical performances of the ACPs depended strongly on activation temperature: The specific surface area increased from 202.92 (500 °C) to 2158.48 m2 g−1 (1100 °C). XRD and Raman analyses revealed that ACP graphitization also increased with the activation temperature. For activation at 1100 °C, the maximum specific capacitance was 255 F g−1, and over 92% of its capacitance was retained after 2000 cycles.

“…Etching [71,72] (i.e. material sputtering in the presence of a chemically active reagent to weaken the atomic bonds on the surface of the material) and deposition [73,74] are the most applied technological operations where plasmas are used [75]. The etching is usually employed for the selective removal of material components to reveal a matrix which can be subsequently filled with another material component to create a complex multimaterial system with the necessary physical and chemical characteristics.…”

Plasma and metamaterials: what new advances in space micro-propulsion systems can they bring when used together? The aim of this concise review article is to attract attention of the space propulsion scientists and engineers, along with experts working in the fields of micromachines, optics, communication, and other hi-tech devices, to the opportunities that arise from different possible combinations of plasma and metamaterials. Along with plasma-based techniques used for the fabrication of complex metamaterials, we examine two unusual plasma/ metamaterial systems, namely when plasma interacts with a metamaterial, and when plasma itself features some properties of a metamaterial. The fundamental physics behind the principal processes that define the behavior of these systems is briefly outlined. Possible applications in space technology, mainly for micro-propulsion systems for Cubesats and small satellites are also sketched.

“…The charged nature of species in plasmas enables one to control their movement in space, allowing for the directional and selective generation of intense fluxes of energy and matter across space. This combination of reactivity and selectivity has made plasmas a useful tool in a variety of systems, from medicine where it can be used to selectively induce apoptotic processes in cancer cells [ 3 , 4 , 5 ], to biology where it can be used to upregulate sugar metabolism and alcohol tolerance in industrial yeast or inhibit resistant bacterial biofilms [ 6 , 7 , 8 ], to agriculture and aquaculture where plasmas can enhance survival and productivity of commercially significant species of plants and fish [ 9 , 10 ]. In addition to changing the behavior of biological objects, plasma-enhanced technologies are used extensively in materials processing and engineering [ 11 , 12 , 13 , 14 ], where plasma-generated species can act as catalysts in material degradation, as building blocks in material assembly, and as modifiers of surface properties.…”

Plasma-enhanced synthesis and modification of polymers is a field that continues to expand and become increasingly more sophisticated. The highly reactive processing environments afforded by the inherently dynamic nature of plasma media are often superior to ambient or thermal environments, offering substantial advantages over other processing methods. The fluxes of energy and matter toward the surface enable rapid and efficient processing, whereas the charged nature of plasma-generated particles provides a means for their control. The range of materials that can be treated by plasmas is incredibly broad, spanning pure polymers, polymer-metal, polymer-wood, polymer-nanocarbon composites, and others. In this review, we briefly outline some of the recent examples of the state-of-the-art in the plasma-based polymer treatment and functionalization techniques.
