Natural dyes serve as a benign alternative to their synthetic counterparts, offering a sustainable option that directly mitigates the release of toxic chemicals. In this study, cotton fabrics were dyed with neem leaf extract in acidic, neutral and alkaline condition where samples were mordanted with lemon juice. The findings revealed a direct correlation between colour strength (K/S) and pH levels, and optimal fastness properties were achieved under alkaline pH conditions when a mordant was employed. The Energy Dispersive X-ray (EDX) ensured the elemental composition of lemon juice assisted dyed fabric which indicates the effective binding of cotton fabric with neem leaves extracted dye. The Fourier Transform Infrared (FTIR) Spectroscopy analysis also confirmed the interaction of cotton fabric with dye particles. The results indicate that cotton fabric can be successfully dyed with neem leaf extract and lemon juice as the biomordant, presenting an eco-friendly and sustainable approach to dyeing practices. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

The performance of wet and advanced oxidation processes is considered to have many weaknesses concerning ozone and peroxone, specifically their characteristics against persistent organic compounds, as well as nitrogen-ammonia and amine-phenolic-based compounds. This is necessary to increase and improve the performance of the utilized plasma reactor, specifically the finer bubble size, as well as the intensity and reactivity (chemical reaction barriers) of the reacting species, to have a smaller impact on mass transfer or diffusivity in polar solvents. Therefore, this study aims to analyze the hydrodynamic characterization and several tests of the most important physicochemical parameters of a prototype nanobubble plasma ozone reactor, which is a reaction vehicle integrating the synergistic effect of a cold field. This reactor was used with a nanobubble-producing nozzle in a PFR (plug flow reactor), to increase the absorption ability of the plasma by water. The results showed that the oxygen and ozone solubilities, H₂O₂ production, and the synergy of these species were strongly influenced by the electric voltage, feed gas flow rate, and the O₂ purity used in the injection system. © 2022

As the chemical industry shifts toward sustainable practices, there is a growing initiative to replace conventional fossil-derived solvents with environmentally friendly alternatives such as ionic liquids (ILs) and deep eutectic solvents (DESs). Artificial intelligence (AI) plays a key role in the discovery and design of novel solvents and the development of green processes. This review explores the latest advancements in AI-assisted solvent screening with a specific focus on machine learning (ML) models for physicochemical property prediction and separation process design. Additionally, this paper highlights recent progress in the development of automated high-throughput (HT) platforms for solvent screening. Finally, this paper discusses the challenges and prospects of ML-driven HT strategies for green solvent design and optimization. To this end, this review provides key insights to advance solvent screening strategies for future chemical and separation processes. © 2025 The Authors.

We developed a method to form a copper seed layer directly on resins with excellent dielectric properties using sputtering (referred to as the direct sputtering method). One of the key challenges to implementing 6G wireless communication systems that use millimeter waves is minimizing high-frequency transmission losses, as the transmission loss is affected by the dielectric (resin substrate) and the conductor (copper wiring) used to fabricate the transmission line. We compared our direct sputtering method for fabricating transmission circuits with the electroless copper plating method by evaluating the characteristics of their high-frequency transmission up to 100 GHz. Our direct sputtering method has several advantages over the electroless copper plating method, including a streamlined fabrication process for the transmission circuit. The direct sputtering method reduces the usage of chemicals and the high-frequency transmission loss in the transmission circuit. Thus, our direct sputtering method is beneficial to the fabrication of transmission circuits for 6G wireless communications. © 2024 IEEE.
