“…A significant part of research in the field of organic polymers has been specifically focused on porous organic polymers, given their distinct advantages and extensive applications across various fields. [1][2][3][4] Porous organic polymers are mainly recognized as different groups such as covalent organic frameworks (COFs), [5] covalent triazine frameworks (CTFs), [6] hydrogen-bonded organic frameworks, [7] conjugated microporous polymers, [8] and also porous aromatic frameworks. [9] The International Union of Pure and Applied Chemistry categorizes porous polymers into three groups microporous, mesoporous, and macroporous which feature pore sizes of less than 2, 2-50, and >50 nm, respectively.…”

The development of efficient drug delivery systems is essential for improving the efficacy and safety of cancer drugs, particularly for aggressive and difficult‐to‐treat cancers. Covalent organic frameworks (COFs) are emerging as innovative porous nanomaterials in drug delivery systems (DDS), due to their unique properties, including the metal‐free organic skeleton, predetermined structures and pore geometries, high porosity, large surface area, facile surface modification potential, and good biocompatibility. These characteristics make COFs excellent candidates for improving drug delivery by enhancing drug loading capacity and enabling precise encapsulation. This review emphasizes the importance of donor‐acceptor‐based COFs, which provide channels for charge transportation, and we also explore how the π‐conjugated skeleton of COFs enhances its long‐acting fluorescent properties and facilitates drug uptake via cell endocytosis. While this review primarily focuses on recent advancements in COF‐based targeted DDS, it also acknowledges the challenges posed by the diverse pore geometries in porous materials and discusses potential solutions. Further, it underlines the potential of developing future drug carriers that can successfully and specifically target cancer cells, improving treatment efficiency while reducing adverse side effects.

“…The use of AOP methods for the total elimination of CV from wastewater had been widely studied: many papers communicate the use of photocatalytic active solids working in the presence of UV or visible light to degrade or even better, mineralize the dye. As in other photocatalytic reactions, titanium dioxide-based solids proved to be effective in the CV removal from diluted aqueous solutions [18][19][20][21]. Senthilkumaar and Porkodi [22] investigated the CV photodegradation using an open reactor equipped with a 125 W lamp, by using P-25 and titania prepared by the sol-gel method.…”

“…Commonly, two methods are used for nano-catalyst synthesis; the first is the chemical method and the second is through the green method. In the chemical synthesis method, different chemicals are used with strong reagents and solvents which increases eco-toxicological concerns, while the green synthesis method is safe and environmentally friendly as it involves the use of enzymes, microbes, and plant exudates [32]. Plant exudates are basic substrates, selected for nanoparticle synthesis because they contain stabilizers, natural reducing agents, surfactants, and environment-friendly properties.…”

In the current study, a novel green nano-catalyst from Tragacanth gum (TG) was synthesized and used for sustainable biodiesel production from Brassica juncea (L.) Czern. seed oil. Brassica juncea (L.) Czern contains 30% oil on dry basis and free fatty acid content of 0.43 mg KOH/g. Physiochemical characterization of a newly synthesized nano-catalyst was performed by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), Transmission Electron Microscopy (TEM), and Fourier Transform Infrared Spectroscopy (FT-IR) analysis. The XRD results showed an average crystalline size of 39.29 nm. TEM analysis showed the cluster form of NiSO4 nanoparticles with a size range from 30–50.5 nm. SEM analysis of the catalyst showed semispherical and ovoid shapes with surface agglomeration. The synthesized catalyst was recovered and re-used in four repeated transesterification cycles. Maximum biodiesel yield (93%) was accomplished at 6:1 methanol to oil molar ratio, catalyst concentration of 0.3 wt%, at 90 °C for 120 min at 600 rpm using Response Surface Methodology (RSM) coupled with central composite design (CCD). Brassica juncea (L.) Czern. biodiesel was characterized by Thin Layer Chromatography (TLC), FT-IR, Nuclear Magnetic Resonance (NMR) (1H, 13C), and Gas Chromatography-Mass Spectroscopy (GCMS) analytical techniques. The major fatty acid methyl esters were 16-Octadecenoic acid and 9-Octadecenoic acid methyl ester. The fuel properties, i.e., flash point (97 °C), density (825 kg/m3 at 40 °C), kinematic viscosity (4.66 mm2/s), pour point (–10 °C), cloud point (–14 °C), sulfur content (66 wt.%), and total acid number (182 mg KOH/g) were according to the International biodiesel standards. The reaction kinetic parameters were determined, and all the reactions followed Pseudo first-order kinetics. It was concluded that non-edible Brassica juncea (L.) Czern. seed oil is one of the sustainable candidates for the future biofuel industry using a cleaner, reusable, and highly active Ni-modified TG nano-catalyst.
