“…The 2% hBN/CMC ink has the highest value of k = 307 ± 0.3, and the bare CMC ink has the lowest value of k = 160 ± 0.2. The higher the k value, the higher the ability of the ink to exhibit a solid-like behavior post-extrusion . This observation is further supported by the shear/apparent viscosity of the inks measured at a static shear rate of 100 s –1 (Table ).…”

As a natural polymer, cellulose is abundant, low-cost, robust, and biodegradable and can be chemically modified. This work explores the enhancement of mechanical, thermal, and flexoelectric properties of three-dimensional (3D)-printed carboxymethyl cellulose (CMC) due to the addition of mechanically exfoliated hexagonal boron nitride (hBN). hBN was observed to act as a rheology modifier, and CMC reinforced with 2% hBN exhibited the maximum apparent viscosity of 12.24 Pa•s at a shear rate of 100 s −1 . The 0.5% hBN/CMC film exhibited the highest mechanical and thermal stability. A flexoelectric energy harvester was fabricated out of 3D-printed hBN/CMC composites to test the effectiveness of strain-induced charge production. By varying the load resistance and applied pressure, we were able to measure the voltage and current flowing through the device. We found that a load resistance of 180 kΩ connected across a 2% hBN/CMC device resulted in the highest power delivery of 5.5 nW. When mechanical strain is applied, a charge state fluctuation and spontaneous polarization in the hBN/CMC matrix are seen. This phenomenon can be explained based on the flexoelectric energy-harvesting mechanism, supported by density functional theory (DFT) calculations.

“…These stages are directly connected with the rheological properties, including viscosity, yield stress and elastic modulus (G′), and viscous modulus (G″) [ 33 ]. Extrusion correlates with yield stress and it is worth noting that, although the smaller the yield stress, the easier for the material to be extruded, it also implied that the mechanical strength of the material may be unfavorable for the subsequent self-support and deformation resistance of the material extrusion [ 34 ].…”

Recently, personalized meals and customized food design by means of 3D printing technology have been considered over traditional food manufacturing methods. This study examined the effects of different proteins (soy, cricket, and egg albumin protein) in two concentrations (3% and 5%) on rheological, textural, and 3D printing characteristics. The textural and microstructural properties of different formulations were evaluated and compared. The addition of soy and cricket protein induced an increase in yield stress (τ₀), storage modulus (G′), and loss modulus (G″) while egg albumin protein decreased these parameters. The textural analysis (back extrusion and force of extrusion) demonstrated the relationship between increasing the amount of protein in the formula with an improvement in consistency and index of viscosity. These values showed a straight correlation with the printability of fortified formulas. 3D printing of the different formulas revealed that soy and cricket proteins allow the targeting of complex geometry with multilayers.

“…With oleogels’ applicability, bigels can serve as reliable vehicles for bioactive molecules regardless of their hydrophilic or hydrophobic nature. Previous work on the printability and rheological properties of bigel inks showed that the 80% oleogel fraction group was an ideal material for the 3D printing [ 93 ]. 3D food printing is an excellent tool for personalised nutrition about particular dietary necessities (e.g., obesity).…”

Nowadays, edible materials such as polysaccharides have gained attention due to their valuable attributes, especially gelling property. Polysaccharide-based edible gels (PEGs) can be classified as (i) hydrogels, (ii) oleogels and bigels, (iii) and aerogels, cryogels and xerogels, respectively. PEGs have different characteristics and benefits depending on the functional groups of polysaccharide chains (e.g., carboxylic, sulphonic, amino, methoxyl) and on the preparation method. However, PEGs are found in the incipient phase of research and most studies are related to their preparation, characterization, sustainable raw materials, and applicability. Furthermore, all these aspects are treated separately for each class of PEG, without offering an overview of those already obtained PEGs. The novelty of this manuscript is to offer an overview of the classification, definition, formulation, and characterization of PEGs. Furthermore, the applicability of PEGs in the food sector (e.g., food packaging, improving food profile agent, delivery systems) and in the medical/pharmaceutical sector is also critically discussed. Ultimately, the correlation between PEG consumption and polysaccharides properties for human health (e.g., intestinal microecology, “bridge effect” in obesity, gut microbiota) are critically discussed for the first time. Bigels may be valuable for use as ink for 3D food printing in personalized diets for human health treatment. PEGs have a significant role in developing smart materials as both ingredients and coatings and methods, and techniques for exploring PEGs are essential. PEGs as carriers of bioactive compounds have a demonstrated effect on obesity. All the physical, chemical, and biological interactions among PEGs and other organic and inorganic structures should be investigated.
