Silver Nanoparticles in Comparison with Ionic Liquid and rGO as Gate Dopant for Paper–Pencil-Based Flexible Field-Effect Transistors

Solvent-free fabrication of a biodegradable all-carbon paper based field effect transistor for human motion detection through strain sensing

“…S1 †). The mobility values obtained in this experiment are comparable to the mobility of FET on paper in which the pencil trace serves as the channel and the ion gel as the dielectric 16,23 and are lower compared to the graphite on SiO 2 FET 19 but higher compared to organic FETs 38,39,42 and reduced graphene oxide (rgo) based FETs. 24,41 Graphite FET on a paper is exploited as a strain sensor with zero gate voltage as shown in Fig.…”

Silver and molybdenum disulfide nanoparticles synthesized in situ in dimethylformamide as dielectric for micro-electro discharge machining

“…The supernatant served as the solution containing silver NPs. 11 Synthesis of MOS 2 -NPs was conducted by mixing and ultrasonication of 20 mg MOS 2 powder with 40 mL DMF containing 10 mg PVP using a probe sonicator for 1 h followed by centrifugation of yellowish black mixture at 7000 r/min for 10 min. The supernatant hosted MOS 2 -NPs synthesized in situ in DMF solution.…”

Gold nanoparticle embedded paper with mechanically exfoliated graphite as flexible supercapacitor electrodes

“…The crystalline nature of exfoliated graphite layers from pencil lead on paper has recently been reported using TEM (transmission electron microscope) images of pencil lead manually rubbed on a solid substrate. 20,21 The separator was a paper soaked in a Ni-Cu hydroxide complex containing excess KOH. Ni-Cu complex was used as these transition metal oxides and hydroxides posses high pseudocapacitance, 22 …”
