Two-dimensional (2D) nanomaterials have been the focus of substantial research interest recently owing to their fascinating and excellent properties. However, 2D porous materials remained quite rare due difficulty creating pores in nanostructures. Here, we synthesized a novel type single-layered mesoporous TiO2 nanosheets with very uniform size thickness as well ordered mesostructure from an unprecedented hydrothermal-induced solvent-confined assembly approach. The F127/TiO2 spherical...
Nowadays, energy storage system is utilized in many countries for planning the future. The changes solar radiation lead to overproduction of electricity a photovoltaic generator. A hybrid would play an important role enhancing reliability power generation using system. microgrid indispensable infrastructure smart grid systems. In this paper, within PV analysed. configuration and topologies are analysed with electronic interference, control scheme, optimization renewable source general sizing...
Abstract Liquid‐phase exfoliation, a technique for enhancing the properties of biochar, has been recognized as effective, circumventing limitations other methods such high expenses, scalability, and complexity. This study explored synergistic effect achieved by combining chicken feathers with elephant grass to create composite feedstock biochar production. The was subjected liquid‐phase exfoliation using acid acetone. Elemental analysis indicated that co‐carbonization combined biomass...
Porous-activated carbon (PAC) materials have been playing a vital role in meeting the challenges of ever-increasing demand for alternative clean and sustainable energy technologies. In present scenario, facile approach is suggested to produce hierarchical PAC at different activation temperatures range 600 900 °C by using cow dung (CD) waste as precursor, H3PO4 adopted nonconventional activating agent obtain large surface area values. The as-prepared dung-based (CDPAC) graphitic nature with...
Early and automatic detection of colorectal tumors is essential for cancer analysis, the same implemented using computer-aided diagnosis (CAD). A computerized tomography (CT) image colon being used to identify carcinoma. Digital imaging communication in medicine (DICOM) a standard medical format process analyze images digitally. Accurate tumor cells complex digestive tract necessary optimal treatment. The proposed work divided into two phases. first phase involves segmentation, second...
This work presents the loading of zeolite with nano iron oxide, samples has been prepared by a simple chemical route. The structural, morphological and magnetic properties products were determined X-ray diffractometer (XRD),Transmission electron microscope (TEM) vibrating sample magnetometer (VSM). average crystallite sizes obtained from doped nanomaterials 4-6 nm. VSM results showed that, acquire after doping Nano oxide.
The encapsulation of functional colloidal nanoparticles (100 nm) into single-crystalline ZSM-5 zeolites, aiming to create uniform core-shell structures, is a highly sought-after yet formidable objective due significant lattice mismatch and distinct crystallization properties. In this study, we demonstrate the fabrication structured single-crystal zeolite encompassing an Fe
A series of non-symmetrical Schiff base liquid crystals were prepared and investigated. bases p-alkyloxy aniline derivatives 4-phenyl pyridine-4′-carbaldehyde synthesized. The terminal alkoxy groups substituting are varied chain length, namely C6, C8, C16. structures the compounds confirmed via 1H NMR 13C spectroscopy. Different mesophases samples thermally optically characterized by differential thermal analysis (DSC) polarized optical microscopy (POM). All revealed enantiotropic smectic B...
A series of new supramolecular three-ring bent-shape Schiff base liquid crystal (LC) complexes were prepared and studied. On one side, two alkoxy chain lengths the carboxylic acids used, namely eight sixteen carbons. Moreover, on other terminal small compact groups, which substituted aniline, with different polarities utilized. Furthermore, hydrogen-bonding interactions in formed elucidated by Fourier-transform infrared (FT–IR) spectroscopy. The mesomorphic thermal optical characteristics...
Tremendous efforts have been made in recent years to synthesize ordered mesoporous zeolite materials, because of the accelerating demands industrial bulky molecule conversion. Here, we develop a novel gradient acidic assembly growth strategy prepare highly zeolitized aluminosilicate (SBA-16) materials mixed template system. This can achieve high zeolitization walls without any ordering loss mesostructure. The resultant composed intergrown subcrystal particles (2–3 nm), exhibit surface area...
Supramolecular three-ring Schiff base novel liquid crystal complexes have been prepared and investigated. bases of para-substituted aniline derivatives para-pyridine carbaldehyde then mixed in equimolar quantities with para-alkoxy benzoic acids. On one side, the alkoxy chain length varies from 8 to 16 carbon atoms. other terminal small compact groups substituting various polarities are used. Hydrogen-bonding interaction was elucidated by FTIR spectroscopy. The mesomorphic thermal optical...
