The development of heteropoly acid (HPA)-based functional soft materials is an important topic in material science and energy devices. The noncovalent supramolecular strategy has continued to evolve in its capacity to create innovative HPA materials with increasingly complex functions that are not accessible using conventional covalent synthesis. In this study, we explored a type of HPA-containing conductive adhesive via a simple noncovalent strategy. We demonstrated that concomitant ionic bonds, hydrogen bonds, charge-transfer interactions, π-π stacking, and hydrophobic effects enable aromatic amino acids, HPAs, and carbon materials to crosslink with each other. Consequently, the formed soft materials exhibited collective advantages, such as exceptional wet adhesion to flexible substrates and electrolytes, adaptive and deformable properties, and conduction and reversible redox behavior. These features allow us to fabricate flexible two-dimensional (2D) supercapacitors (SCs) by conveniently injecting all-in-one adhesives onto flexible substrates. The capacitance retention of the fabricated flexible SC was 92% during bending and folding deformation. In particular, the adhesives can be patterned into tandem 2D SCs for high-voltage output with metal-free interconnects.

The research focuses on the applicability of silver (Ag) and molybdenum disulfide (MOS2) nanoparticle synthesized in situ in dimethylformamide solution as dielectric material for micro-electro discharge machining. Ag nanoparticles (~120 nm size) and MOS2 nanoparticles (~20 nm size) were synthesized in dimethylformamide solution using a combination of nanoparticle solution synthesis routes. A setup for micro-electro discharge machining was developed in-house with an arrangement to generate spark at varying voltages. The setup was integrated with a precise linear height gauge to measure the spark gap during the experiments where Ag and MOS2 nanoparticles in dimethylformamide solution served as dielectric. The debris was collected and was characterized for each of the experiments. The feature size of the crater generated during the micro-electro discharge machining was also studied. The experiments were repeated with silver and MOS2 nanoparticle powder mixed with dimethylformamide as dielectric. It was observed that in situ prepared nanoparticles in dimethylformamide offered much better machining performance in terms of process stability, crater size and material removal rates. On use of in situ synthesized nanoparticle dielectric, the material removal rate increased by nearly two to three times whereas the spark gap increased by about two times.

“…The results obtained revealed that exfoliated graphite electrode offers lower capacitance, high electrochemical surface area (90 mm 2 ), and better electron transfer than both electrodes (Winter and Woock, 1965). Hence, this electrode has attracted various researchers in employing exfoliated graphite electrodes for various electrochemical applications, including sensor development, water treatment, supercapacitors, and biosensors to name a few (Somashekarappa and Sampath, 2004;Ion et al, 2011;Mandal et al, 2015). The application of exfoliated graphite is discussed in the next section.…”

Exfoliated graphite is a 2D carbon material that has recently received great attention owing to its remarkable analytical merits such as fast electron migration, ease of surface regeneration, high-temperature resistance, ability to withstand high-current density, excellent conductivity, and sensitivity. Due to its excellent analytical signature, an exfoliated graphite electrode has been reportedly used in the construction of sensors and biosensors for various applications. This electrode can be used alone or blended with several nanomaterials/semiconductors for the degradation of various organic pollutants in wastewater. Despite the outstanding results reported in the use of exfoliated graphite electrodes for various analytical applications, very few reports were documented in the literature. Therefore, this review elaborated on the importance of exfoliated graphite electrodes for electrochemical analysis.
