As the population increases and manufacturing grows, greenhouse gas other harmful emissions increase. Contaminated with chemicals such as dyes, pesticides, pharmaceuticals, oil, heavy metals or radionuclides, wastewater purification has become an urgent issue. Various technologies exist that can remove these contaminants from sources, but they often demand high energy and/or cost, in some cases produce contaminant laden sludge requires safe disposal. The need for methods which are less capital intensive, operationally costly more environmentally friendly is suggested. Cellulose-based materials have emerged promising candidates treatment due to their renewability, low biodegradability, hydrophilicity, antimicrobial property. In this review article, we focussed on developing sustainable biodegradable cellulose-based treatment. This article deals materials' scope conversion into valuable products like hydrogel, aerogel, cellulose composites, nanocellulose. no environmental impact plentiful. modified applying membrane, adsorbent, sorbent, beads purify were discussed. Finally, challenges future prospects of considered, emphasizing potential be eco-friendly alternatives traditional used

This review concerns deep eutectic solvents (DES) and how they can be exploited in the preparation of new improved electrochemical sensing platforms. Some relevant properties DES are described, with a brief description range applications recent advances concerning coatings materials prepared DES. Their use modified-electrode sensors biosensors publications is then addressed, particularly regarding electroactive redox polymer-modified electrodes, together nanomaterials, including employing ternary to increase sensitivity. Future perspectives indicated.

Abstract There has been a significant scope toward the cutting‐edge investigations in hierarchical carbon nanostructured electrodes originating from cellulosic materials, such as cellulose nanofibers, available natural and bacterial cellulose. Elements of energy storage systems (ESSs) are typically established upon inorganic/metal mixtures, carbonaceous implications, petroleum‐derived hydrocarbon chemicals. However, these conventional substances may need help fulfilling ever‐increasing needs ESSs. Nanocellulose grown significantly an impressive 1D element due to its availability, eco‐friendliness, recyclability, structural identity, simple transformation, dimensional durability. Here, this review article, we have discussed role overview cellulose‐based hydrogels Additionally, extraction sources solvents used for dissolution detail. Finally, properties (such self‐healing, transparency, strength swelling behavior), applications flexible batteries, fuel cells, solar supercapacitors carbon‐based derived cellulose) devices conclusion with existing challenges updated recent findings.

Nanomedicine has been essential in bioimaging and cancer therapy recent years. Nanoscale covalent–organic frameworks (COFs) have growing as an adequate classification of biomedical nanomaterials with practical application prospects because their increased porosity, functionality, biocompatibility. The high sponginess COFs enables the incorporation distinct imaging therapeutic mechanisms a better loading efficiency. Nevertheless, preliminary biocompatibility limits possibility for clinical translation. Thus, cutting-edge improved efficiency are highly expected to fast-track translation nanomedicines. inherent effects nanoscale COFs, such proper size, modular pore geometry specific postsynthetic transformation through simple organic changes, make them particularly appealing prospective building blocks may also be postmodified particular binding biomarkers. exceptional features cause encouraging nanocarrier applications. In this review, we systematically discussed advances field theranostics by providing along synthetic methods. Further, applications (such drug delivery systems, photothermal, photodynamic therapy) detail help available literature date. Furthermore, advantages over other materials therapeutics discussed. Finally, review concludes potential future COF theranostic field.

Neurotransmitters are essential chemical messengers required for proper brain function, and any changes in their concentrations can lead to neuronal diseases. Therefore, sensitive selective detection is crucial. This study presents a fast simple colorimetric method dopamine using three reagent solutions: AgNP MPA, Ag/Au nanocomposite, mercaptophenylacetic acid. TEM images showed narrow distribution of Ag Au nanoparticles with average sizes 20 nm 13 nm, respectively, gold bound the edges silver nanoparticles. A paper-based biosensor was created manual wax printing dopamine. Visual onsite color both acid mixture silver–gold nanoparticle composite. Electrochemical glassy carbon electrode modified 8 mM demonstrated high selectivity sensitivity towards dopamine, peak range 0.7–0.9 V. Interferences were minimized, ensuring

Bisphenol compounds play a pivotal role as essential diol monomers in the synthesis of numerous engineering plastics. However, conventional methods for their preparation often involve use concentrated inorganic acids, leading to significant environmental pollution and equipment corrosion. Herein, we developed strong acid-free synergistic catalytic system consisting Lewis–Brønsted acid catalyst composed ZnCl2 3-mercaptopropionic acid. This enabled highly efficient bisphenol through Friedel–Crafts alkylation reaction ketones with phenols or phenoxyethanol. The highest selectivity 9,9-bis[4-(2-hydroxyethoxy)phenyl]fluorene can reach 96.4% at 110 °C 2 h, which was higher than that traditional sulfuric method 85.0%. A mechanistic study revealed carbonyl group ketone first activated by coordination ability Zn2+ from Lewis acid, facilitated subsequent protonation process initiated acidic site Brønsted
