“…As MNP@PMelamine could have a porous micro‐structure, the Brunauer–Emmett–Teller (BET) analysis was also performed to determine the specific surface area and the pore size distribution, as shown in Figure . It can be seen that the adsorption–desorption isotherm curve (Figure a) appearances the characteristic feature of the type‐IV isotherm with an H3 hysteresis loop . This result demonstrates that MNP@PMelamine possesses mesoporous structure.…”

A new magnetic heterogeneous catalyst was synthesized by immobilization of nickel ions onto a cross‐linked polymeric nanocomposite composed of cyanuric chloride, ethylenediamine and functionalized magnetic nanoparticles. The resulting nitrogen rich support was capable of adsorbing large amounts of nickel ions (1.20 mmol g−1). The synthesized catalyst was characterized using AAS, TEM, FT‐IR, EDX, TGA, SEM, BET and XRD techniques. The performance of the prepared catalyst was investigated in the C‐N coupling of arylamines with aryl boronic acids. The reaction was carried out under a mild condition and good to moderate to good yields of products was obtained using only 5.0 mol% of the catalyst. The catalyst was easily recovered and reused for at least 7 times without any significant loss of its activity.

“…The power density of this supercapacitor can reach 26 KW per kg, i.e. 130 times that of lithium-ion batteries (51) . A capacitor required to meet a power demand of 1 MW, using conventional technology, would weigh more than 10 tons while the new supercapacitor would weigh only 40 kg.…”

Objectives: To analyze the primary strategic motives for China venturing into Disruptive Technologies and Innovations R&D at a very rapid pace. China has been galloping the Technology Highway for the past decade, with technological and innovation inroads in almost all the key sectors with the government playing a pivotal role. Method: The apparent drivers for the rapid strides in technology are economic growth, social development and the national aspirations of establishing a powerful and prosperous China. Forays in disruptive technologies has been preceded near-simultaneously by a plethora of strategic geopolitical ventures by China within its land mass, in the various seas, across the Asian, Europe and African continents and also in the space dimension. Thus, the methodology adopted is to study the various strategic initiatives China has implemented in the backdrop of global geopolitics. Thereafter, correlate the disruptive technologies to the various Chinese strategies. Findings: The initiatives to be a world leader in Disruptive Technologies correspond to China's other Strategic programs in global geopolitics and expansionist steps in the five dimensions of Land, Air, Sea, Space and Cyber Space. This cannot be dismissed as a mere coincidence. This study establishes that Technology is the common underlying driver of all the geopolitical overtures, viewed as strategic overlays, by China. Further, it is found that China is boosting R&D on dual-use technologies as compared to the single civil-end use technologies to complement its military component in implementation of its strategic manoeuvres. Application: The study will facilitate in mapping the global repercussions of these technologies, especially in the Indian sub-continent, given the stand-off relationship between the two nations.

“…The PSS, a vinyl polymer having sulfonate (−SO 3 − ) groups promotes para-directed polymerization of aniline, which resulted in the formation of PANI with lower structural defects . A water-soluble PANI:PSS was proposed as an alternative to substitute PEDOT:PSS with high cost and poor redox behaviors [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. The synthesis of PANI:PSS NPs was proposed by simple chemical oxidative polymerization of aniline in the presence of the PSS (Figure 8) [24][25][26][27][28].…”

“…Furthermore, the −SO 3 − groups of PANI:PSS enable electrostatic interactions with various materials, such as carbons, inorganics, and polymers [20][21][22][30][31][32][33][34][35][36][37]. Therefore, various PANI:PSS-based composites were designed for SCs [23,[25][26][27], ECs [28][29][30], supercapacitors [31][32][33][34], sensors [22,24,35,36], antennas [37], and so forth. It was obvious that the PANI:PSS can act as an efficient hole transport layer (HTL) material in perovskite solar cells (PSCs) and organic solar cells (OSCs) [23,25,26].…”

Solution-processable conducting polymers (CPs) are an effective means for producing thin-film electrodes with tunable thickness, and excellent electrical, electrochemical, and optical properties. Especially, solution-processable polyaniline (PANI) composites have drawn a great deal of interest due to of their ease of film-forming, high conductivity up to 103 S/cm, excellent redox behaviors, processability, and scalability. In this review, basic principles, fabrication methods, and applications of solution-processable PANI composites will be discussed. In addition, recent researches on the PANI-based electrodes for solar cells (SCs), electrochromic (EC) windows, thermoelectric (TE) materials, supercapacitors, sensors, antennas, electromagnetic interference (EMI) shielding, organic field-effect transistors (OFETs), and anti-corrosion coatings will be discussed. The presented examples in this review will offer new insights in the design and fabrication of high-performance electrodes from the PANI composite solutions for the development of thin-film electrodes for state-of-art applications.
