• Two novel tetrabenzonaphthalene-linked conjugated microporous polymers (TBN-pH CMPs) were constructed. • These CMPs had large surface areas and outstanding thermal stability. • The TBN-TPA CMP–based electrode had high specific capacitances of 251 F g–1 at 0.5 A g–1. • TBN-TPA CMP material appears promising for charge and energy storage applications. Conjugated microporous polymers (CMPs) have been applied widely in several energy storage applications. Triphenylamine derivatives are good electrode materials that can be processed into SC devices because of their high charge mobilities, unique electronic properties, and high redox activity. We prepared two novel tetrabenzonaphthalene-linked conjugated microporous polymers (TBN-pH CMPs) through [4 + 2] and [4 + 3] Schiff-base condensations of 2,7,10,15-tetra(4-formylphenyl)tetrabenzonaphthalene (TBN-PhCHO) with tetrakis(4-aminophenyl)ethene (TPE-4NH 2) and tris(4-aminophenyl)amine (TPA-3NH 2), respectively. Fourier transform infrared, and solid-state 13C NMR spectroscopy investigated the structures of the as-prepared CMPs. These CMPs, had large surface areas and outstanding thermal stability at temperatures of up to 400 °C, making them suitable for use as electrodes in supercapacitor (SC) systems. Indeed, the TBN-TPA CMP–based electrode had high specific capacitances (251 F g − 1 measured at 0.5 A g–1) and capacity retentions (94%, measured after 5000 cycles at 10 A g–1) when tested in three-electrode systems. We attribute the remarkable electrochemical activity and conductivity of the TBN-TPA CMP electrode to its large specific surface area (230 m2 g–1) and chemical structure featuring stacking of the benzene rings of its redox-active triphenylamine moieties.

• Comparative studies on the basis of presence and absence of minerals. • Discrimination of the mineral body from the settlements. • Pyrrhotite and limonite (iron ore) minerals have been traced. • Mixture Tuned Matched Filtering algorithm produces a better mineral map. Geology majorly deals with the structures, features, minerals, rocks, etc. of the planet Earth. Geologists are using the technology of remote sensing for structural interpretation and regional mapping. Ores and minerals identification are also done with the help of remote sensing. This paper is mainly focused on the identification of minerals and mapping with the help of various algorithms such as Spectral Angle Mapper (SAM), Spectral Feature Fitting (SFF) and Mixture Tuned Matched Filtering (MTMF) using airborne hyperspectral data. Minerals are identified on the basis of the visible and near-infrared spectral reflectance. Spectral reflectance is having absorption features at different positions and absorption peaks are used for the analysis of imagery. This technique provides surface mineralogical details. SAM algorithm mainly computes the angle between the unknown pixel spectrum and unique pixel spectrum. SFF algorithm matched the continuum removed the spectrum of the imagery pixel from the continuum removed reference spectra. MTMF algorithm detects the abundance of the minerals and removes the erroneous positive. Total 13 endmembers (minerals) were identified in the study area. These minerals are grouped into clay minerals, iron minerals, carbonate minerals, and other minerals. These endmembers are used for the mineral map creation from different algorithms. Algorithms produce the diverse kind of mineral map and these are compared with each other on the basis of the mineralogy and discrimination of mineralized region from settlements. Mineral map produced by MTMF algorithm provides convenient results with better accuracy than other algorithms. [ABSTRACT FROM AUTHOR]

• Suzuki one-pot coupling and polycondensation for designing conjugated micrporous polymers. • The TPA-Bz, and TPA-Py CMPs recorded higher thermal stabilities and surface areas upto 1633 mg g −1. • The RhB adsorpativity of TPA-Py CMP reached up to 99% within 5 min and high regeneration stabilities. • Conjugation and planiarities of CMPs affect onto their performances onto various applications. Background: Conjugated microporous polymers CMPs have unique position among porous materials thus they are studied widely. Realistically, triphenylamine (TPA) derivatives generally possess high aromaticity, redox capabilities, high charge motilities, and outstanding electronic features, therefore designing CMPs based on TPA derivatives could result in fantastic properties. Methods: We performed one-pot coupling and polycondensation of a boronated triphenylamine derivative (TPA-3Bor) with bromobenzene (Bz-4Br) and bromopyrene (Py-4Br) derivatives to obtain two new TPA-based conjugated microporous polymers (TPA-Bz and TPA-Py CMPs, respectively). The successful synthesis of two TPA CMPs and their features were examined via Fourier transform infrared (FTIR) and 13C solid state NMR spectroscopies. Significant Findings: These two CMPs displayed attractive adsorptive properties toward the small dye molecule rhodamine B (RhB) from an aqueous solution. Outstanding adsorption performance, rapid kinetics, and good reusability suggest that our CMPs could function as effective adsorbents for RhB and, perhaps, other pollutants from wastewater. Moreover, our TPA-based CMPs displayed effective and stable performance when introduced as electrodes for supercapacitors, with capacitances as high as 78 F g–1 at a current density of 1 A g–1 as well as high stability. This study emphasizes the importance of conjugation and planarity in the future design of such materials. [Display omitted] [ABSTRACT FROM AUTHOR]

The consequences of swift heavy ion (SHI) irradiation (Li3 + , 50 MeV, fluence = 5 × 1013 ions/cm2) on the structural and microscopic magnetic properties of Y3 + -substituted yttrium iron garnet (Y3 + x Fe5 − x O12, x = 0.0, 0.2 and 0.4) have been studied at 300 K. It is found that an additional YFeO3-phase observed along with bcc garnet phase, is completely removed for x = 0.2 composition while its percentage formation considerably reduces for x = 0.4 composition after irradiation. Similar effect has been observed for specimens sintered at 1,500°C. The SHI-induced ion beam mixing has been revealed through X-ray diffraction and Mössbauer spectroscopy. [ABSTRACT FROM AUTHOR]
