Transparent Wood (TW) is a promising composite characterized by lightweight and transparency to visible light, along with its sustainability (see references in [1]). By using successive treatments (i.e., delignification, infiltration with suitable resins and, eventually, functionalization) TW…

Transparent wood (TW) is a sustainable composite material with high optical transmittance and excellent mechanical properties. Nanoparticles, dyes and quantum dots can be added in a controlled manner for new functionalities relying on the light scattering properties of the composite. The scattering…

Electrospinning is a technology largely employed to obtain polymer fibers with different functionalities. The electrospinning of polyvinylpyrrolidone (PVP) in the presence of silica nanoparticles, and the subsequent thermal treatment of these electrospun PVP-silica fibers, allows for the…

Finite element model updating (FEMU) is an advanced inverse parameter identification method capable of identifying multiple parameters in a material model through one or a few well-designed material tests. The method has become more mature thanks to the widespread use of full-field measurement…

Efficient design, production, and optimization of new safe and sustainable by design materials for various industrial sectors is an on-going challenge for our society, poised to escalate in the future. Wood-based composite materials offer an attractive sustainable alternative to high impact…

Artificial intelligence (AI) is a broad term referring to the capability of certain computational systems to perform tasks typically associated with human intelligence, such as reasoning, learning, creativity or pattern recognition. Recent progress in development of AI systems, particularly in their subset known as machine learning (ML), has been helpful in many fields of science and technology. The idea behind ML is that the computational system instead of being explicitly told what to do at each step, is trained with the available data to perform certain tasks it has been designed to.

Transparent Wood (TW) represents a fascinating development in materials science, transforming the ancient, ubiquitous natural composite that is wood into a material possessing optical clarity while retaining many of its inherent advantageous properties. Historically utilized extensively across numerous sectors from construction to art and furniture, wood is renewable and recyclable, aligning perfectly with contemporary circular economy principles. However, its natural opacity, primarily due to the presence of lignin and light scattering within its complex cellular structure, limits its application where transparency is required. The concept of transparent wood was initially explored by Fink in 1992, but it was rediscovered and rigorously investigated by independent research groups starting about a decade ago.

This Guide aims to provide people who are not familiar with Transparent Wood (TW) with an overview on this material, which was discovered in 1992 and thoroughly investigated from 2015 onwards.
