“…Fortuitously, many workers used bio-based nanomaterials to obtain similar properties with biodegradable compounds. Different cellulose nanomaterials were used as additives in coatings (film-forming or oils) to improve their mechanical properties; while nanocellulose is not completely safe either, its effect on health is far inferior, and it is readily biodegradable, unless it underwent too much modification [275][276][277]. As a result, bio-based systems with very high adhesion, hardness, tensile strength and resistance to wear were obtained [59,60,62,64,[66][67][68][69].…”

Increasing the use of wood in buildings is regarded by many as a key solution to tackle climate change. For this reason, a lot of research is carried out to develop new and innovative wood surface improvements and make wood more appealing through features such as increased durability, fire-retardancy, superhydrophobicity, and self-healing. However, in order to have a positive impact on the society, these surface improvements must be applied in real buildings. In this review, the last five years of research in the domain of wood surface improvements and modifications is first presented by sorting the latest innovations into different trends. Afterward, these trends are correlated to specifications representing different normative, ecologic and economic factors which must be considered when expecting to introduce a wood treatment to the market. With this review, the authors hope to help researchers to take into consideration the different factors influencing whether new innovations can leave the research laboratory or not, and thereby facilitate the introduction of new wood surface treatments in the society.

“…The various types of cellulose nanoparticle (also known as nanocellulose, NC) can be classified based on their shape, dimension, function, and preparation method, which in turn primarily depend on the cellulose origin, the isolation and processing conditions as well as the eventual pre-or posttreatment [94,95]. The physicochemical characteristics of cellulose at the nanoscale, such as high specific surface area and aspect ratio, high crystallinity, purity, excellent mechanical properties, and low thermal expansion and density [95][96][97][98][99][100][101], open new prospects for NC use in several fields, including biomedical, environmental, and energy applications [102]. The cellulosic materials having at least one dimension in the nanometer range, based on structure and particle diameters [103], is usually classified into cellulose nanocrystals (CNC), cellulose nanofibers (CNF) and bacterial nanocellulose (BNC).…”

“…CNF have lateral size of several tens of nanometers and length of few microns and, therefore, the aspect ratio of CNF is relatively large [7]. CNF have been isolated through different mechanical disintegration methods, such as high-pressure homogenization, ultrasonication, microfluidization, grinding, cryo-crushing, ball milling, and extrusion [101] or mechanical treatment in combination with chemical or enzymatic hydrolysis. Owing to their high aspect ratio and entanglement, cellulose nanofibers have the potential to be used in many different areas (see Table 4), particularly as strong reinforcement in development of nanocomposites [126,127].…”

The usage of edible coatings (ECs) represents an emerging approach for extending the shelf life of highly perishable foods, such as fresh and fresh-cut fruits and vegetables. This review addresses, in particular, the use of reinforcing agents in film-forming solutions to tailor the physicochemical, mechanical and antimicrobial properties of composite coatings. In this scenario, this review summarizes the available data on the various forms of nanocellulose (NC) typically used in ECs, focusing on the impact of their origin and chemical or physical treatments on their structural properties (morphology and shape, dimension and crystallinity) and their functionality. Moreover, this review also describes the deposition techniques of composite ECs, with details on the food engineering principles in the application methods and formulation optimization. The critical analysis of the recent advances in NC-based ECs contributes to a better understanding of the impact of the incorporation of complex nanoparticles in polymeric matrices on the enhancement of coating properties, as well as on the increase of shelf life and the quality of fruits and vegetables.

“…Two varieties of approaches are generally used for producing cellulose-based composites: (1) the two-stage approach, which involves cellulosic solution achieved through the full dissolution of a cellulose portion that is strengthened by substitutional cellulose, and (2) the one-stage approach through which an incomplete dissolution of cellulose generates a matrix domain sedentary nearby the residual fiber center [49,133].…”

Nanocellulose, the most promising bionanomaterial, is obtained either from the degradation of natural polymers or by the activity of bacteria and microorganisms. These biomaterials present various advantages, including full recyclability, biodegradability, and lack of harmful effects on the human body and environment. Furthermore, nanocelluloses are candidates to fabricate thin transparent layers, fibers, hydrogels, and aerogels due to their remarkable optical, thermal, and mechanical behaviors, including high crystallinity, Young's modulus, and porosity content. These exceptional properties present the superb potential of these materials for the device of environmentally engineered tenable products. This paper presents an outline of the contemporary nanocellulose research works as well as details and information on the nanocellulose materials, especially the synthesis process of composites, along with the areas in which these materials can be utilized, such as energy, flocculant, pollution sensors, and catalysts, to respond to the rising requests of these materials.
