“…Surfactants of a natural origin offer the unique features of biocompatibility, biodegradability, low toxicity, and high abundance, with relatively low cost materials. [ 12 ] As reported by several studies (Table 1), MWCNTs dispersion in deionized water can be successfully achieved by using gum Arabic (GA), [ 13 ] nanofibrillated cellulose, [ 14 ] and lignin. [ 15 ] Although these contributions are interesting, none of them is thoroughly investigated by previous researchers in terms of comparative analysis on both chemistry and printing quality of MWCNTs ink developed by green and synthetic surfactants.…”

While the efficiency of synthetic surfactants in controlling the dispersion behaviour of nanomaterials in aqueous solution has been well documented, issues on environmental impact remain unsolved. The aim of this study is to synthesize multi‐walled carbon nanotubes (MWCNTs) inks using green surfactants and their chemical, physical, and electrical performances are compared to those of synthetic surfactant inks. The conductive ink is synthesized by dispersing MWCNTs in surfactant solution (gum Arabic [GA], alkali lignin [AL], polyvinylpyrrolidone [PVP] or pluronic F‐127 [PL]) with various concentrations. Among four investigated surfactants, GA/MWCNTs and PVP/MWCNTs inks are selected for further investigation due to their excellent dispersion stability. The printability of both inks is assessed by analyzing the quality of the conductive patterns printed with different inkjet printers theoretically and experimentally. It is found that multi‐nozzle printer is capable of developing printed patterns with lower sheet resistance compared to single‐nozzle printer. Overall, 5 GA/MWCNTs ink recorded as the most stable ink with only 14.4% reduction of absorbance after 30 days and with zeta potential value of −40.3 ± 5.36 mV. Ten layers of 5 GA/MWCNTs ink printed on PVA demonstrate a dense MWCNTs networks, which contribute to the lowest surface resistance of 3.0 kΩ sq−1.

“…The cellulose nanocrystals [159] (Fig. 10d), multi-walled CNT-coated cellulose [160] are commonly used substrates whereas cellulose acetate [161] is reported as encapsulating material for OLEDs. For the electrode in OLEDs, biodegradable silk fibroin (SF) [162] and photopolymer based SF [163], PEDOT:PSS/single-walled CNTs based compound film [164] give satisfactory performance in terms of conductivity, and transmittance.…”

The development of Printed Circuit boards (PCBs) has so far followed a traditional linear economy value chain, leading to high volumes of waste production and loss of value at the end-of-life. Consequentially, the electronics industry requires a transition to more sustainable practices. This review article presents an overview of the potential solutions and new opportunities that may arise from the greater use of emerging sustainable materials and resource-efficient manufacturing. A brief contextual summary about how the international management of Waste PCBs (WPCBs) and legalization have evolved over the past 20 years is presented along with a review of the existing materials used in PCBs. The environmental and human health assessment of these materials relative to their usage with PCBs is also explained. This enables the identification of which eco-friendly materials and new technologies will be needed to improve the sustainability of the industry. Following this, a comprehensive analysis of existing WPCB processing is presented. Finally, a detailed review of potential solutions is provided, which has been partitioned by the use of emerging sustainable materials and resource-efficient manufacturing. It is hoped that this discussion will transform existing manufacturing facilities and inform policies, which currently focus on waste management towards waste reduction and zero waste.

“…Compared with SWCNTs, MWCNTs are easier to manufacture and commercialize. MWCNTs have unique electronic and structural characteristics, such as large size, large specific surface area, high conductivity, and good biocompatibility (Mashkour et al., 2018). Therefore, MWCNTs have been widely used in the electrochemical assessment of fish freshness.…”

Meat and aquatic products are susceptible to spoilage during distribution, transportation, and storage, increasing the urgency of freshness evaluation. Engineered nanomaterials (ENMs) typically with the diameter in the range of 1–100 nm exhibit fascinating physicochemical properties. ENMs‐based sensing systems have received extensive attention for food freshness assessment due to the advantages of being fast, simple, and sensitive. This review focuses on summarizing the recent application of ENMs‐based sensing systems for food freshness detection. First, chemical indicators related to the freshness of meat and aquatic products are described. Then, how to apply the ENMs including noble metal nanomaterials, metal oxide nanomaterials, carbon nanomaterials, and metal–organic frameworks for the construction of different sensing systems were described. Besides, the recent advance in ENMs‐based colorimetric, fluorescent, electrochemical, and surface‐enhanced Raman spectroscopy sensing systems for assessing the freshness of meat and aquatic products were outlined. Finally, the challenges and future research perspectives for the application of ENMs‐based sensing systems were discussed. The ENMs‐based sensing systems have been demonstrated as effective tools for freshness evaluation. The sensing performance of ENMs employed in different sensing systems depends on their composition, size, shape, and stability of nanoparticles. For the real application of ENMs in food industries, the risks and regulatory issues associated with nanomaterials need to be further considered. With the continuous development of nanomaterials and sensing devices, the ENMs‐based sensors are expected to be applied in‐field for rapid detection of the freshness of meat and aquatic products in the future.
