Transparent wood (TW)‐based materials have increasingly become the focus of researchers worldwide owing to their superior physico‐chemical‐optical properties, sustainable nature, as well as the fact that they are highly accommodating frameworks that can act as building blocks to readily explore a vast range of potential functionalities, holding great potential to displace glass and plastics in their various respective applications. The integration of multiple functionalities into TW has been undertaken to fulfill the demands of prospective sophisticated applications through the utilization of functional fillers or coatings. Herein, the up‐to‐date foundational developments and reports concerning emergent TW composites and coatings from a perspective of fabrication‐functionality‐application are comprehensively summarized, with a particular focus on seven specific functionalities; i) solar control; ii) chromically‐responsive, iii) electrically‐conductive, iv) shape‐memory active; v) flame‐retardant; vi) electromagnetic interference shielding; and vii) aesthetics. The potential applications of TW with these functionalities are also discussed. Finally, the current challenge with TW is addressed, as well as the future developments required for eventual real‐world application.

“…A schematic representation of the fabrication of functionalized transparent wood is depicted in Figure 19. Muhammad and co-workers demonstrated that functionalized transparent wood is able to act as an efficient X-ray shielding material [40]. For this purpose, sonokeling wood was first delignified (by means of H2O2 treatment carried out at 60 °C for 3, 6, or 9 h) and then treated with a poly(vinyl alcohol)/gelatin solution, containing 0.1, 0.3, or 0.5 g of BaCO3 as an X-ray shielding product.…”

Human history is largely characterized by the massive use of wood, the most well-known natural composite material, possessing unique thermal, mechanical, and environmental features that make it suitable for several applications, ranging from civil engineering, art, and household uses, to business uses (including furniture, stationery, shipbuilding, and fuel). Further, as a renewable and recyclable biomass, wood perfectly matches the current circular economy concept. However, because of its structure and composition, wood is not transparent: therefore, the possibility of removing the embedded lignin, hence limiting the light-scattering phenomena, has been investigated over the last ten to fifteen years, hence obtaining the so-called “transparent wood (TW)”. This latter represents an up-to-date key material, as it can be utilized as obtained or further functionalized, combining the transparency with other features (such as flame retardance, energy storage ability, and environmental protection, among others), which widen the potential (and practical) applications of wood. The present manuscript aims at summarizing first the current methods employed for obtaining transparent wood, and then the latest achievements concerning the properties of transparent wood, providing the reader with some perspectives about its novel functionalizations and applications.

“…In order to protect the health and safety of radiation workers, X-ray shielding materials are needed for the construction of diagnostic X-ray machine rooms. Radiation shielding materials have been widely reported worldwide in recent years, mainly including concrete [17], metal materials [18], heavy metals such as lead and its oxides, and polymer-based composites [19,20]. Cement and concrete, which are bulky and prone to cracking, are mainly used for fixed protection, such as in buildings [21,22], while lead shielding materials have poor mechanical strength, are toxic, scatter more low-energy X-rays, and are more costly [23,24].…”

Iron-bearing dust is one of the main solid wastes in the metallurgical industry, and currently, it is mainly disposed of according to accumulation, which brings great environmental risks. Therefore, this paper proposes a method of preparing X-ray shielding materials by hot pressing using iron-bearing dust as the filler and polyimide resin powder as the matrix. A CT imaging system was used to test the X-ray shielding performance of the materials. The results demonstrated that shielding material I-95 had a shielding percentage of more than 95% at a tube voltage of 55 kVp and a tube current of 2 mA, and the thickness of the half-value layer was less than 0.68 mm. The shielding percentage and mass attenuation coefficient of the composites showed an increasing trend with increased filler addition, tube voltage, and tube current intensity, while the half-value layer thickness showed the opposite trend. Furthermore, the shielding percentage of composites with different fillers was affected by the voltage and hardly affected by the current variation. The dominant part of the shielding material interaction across the tested tube voltage range was photoelectric absorption. The prepared composite is a low-cost material and has high efficiency and is an ideal medical X-ray shielding material.
