“…Efforts are underway to create commercially feasible new or alternative methods with minimal toxicity due to the harmful effects of traditional wood preservatives. Nanotechnology is being presented as a complementary option to traditional wood preservatives for several reasons [18]. Wood is composed of nanotubes known as "nanofibrils."…”

Technology is advancing rapidly, especially nanotechnology research, which maximizes material value by processing matter on extremely small scales. After nanotechnology emerged, architects worldwide tried to comprehend, invest in, and use it to improve products. Research began to improve materials' efficiency by regulating their molecules to improve or add features. Preventing color change by painting buildings with self-cleaning, anti-scratch, and anti-bacterial paint. Nanomaterials are more efficient for building exteriors. They also reduce maintenance costs, rationalize energy use, and improve user comfort. Spreading awareness of Nano-treated materials, which are the cheapest in actual costs throughout operation and maintenance, even if their initial cost is higher, is crucial. The research aimed to determine the design principles and standards that must be followed when using nanotechnology in finishing the facades of administrative buildings to achieve the lowest cost, the shortest period for implementation, and the highest performance efficiency of the building. The study relied on an inductive approach based on theoretical studies, as it dealt with the study of the concept of nanotechnology within finishing materials, its principles and features, and the most important applications of nanotechnology that affect the finishes of building facades. The research study dealt with Nano applications in the field of architecture, so that they achieve the goals and standards of building sustainability, and are used in the finishes of the external facades of buildings to reduce the cost, rationalize energy consumption, and extend the life span of the building, and have an advantage in terms of function and economic return in the long term.

“…Graphene oxide (GO) is a two-dimensional material with single-layer carbon atoms and numerous functional groups providing it with high reactivity. Numerous scientific projects have proven that this nanomaterial increases mechanical strength and contributes to an increase in the hydrophobicity of materials [6,9,10]. From the practical point of view of maintaining the durability of wood, increasing its strength and resistance to moisture are key elements in maintaining its durability.…”

This work carried out research to determine the possibilities of using graphene oxide to provide wood with new functional features. With the saturation parameters used and working liquid with a concentration of 0.004% graphene oxide, the retention of the nanomaterial in wood was 0.25 kg/m3. The presence of graphene oxide increased the crystallinity of the wood to 64% (compared with 57% for unmodified wood). The TG/DTG spectra of wood impregnated with graphene oxide and the control wood indicated that the initial weight loss of the samples observed at a temperature of 100 °C was similar and amounted to less than 4%. A second mass loss was observed in a temperature range of 270 to 380 °C. The mass loss in this temperature range reached 70% and was similar in the test and control samples. Wood modified with graphene oxide showed increased thermal stability in a temperature range of 360 to 660 °C compared with native wood. Given the results obtained, there were no statistically significant differences in the water absorption of modified or control wood. The presence of low concentrations of graphene oxide in the culture medium did not inhibit the growth of the fungus Trichoderma viride; however, a decrease in the growth activity of mycelial hyphae was observed with an increasing concentration of nanomaterial in the medium. It has been reported that graphene oxide, as a stress factor, initiates changes at the cellular level, characterized by the formation of structures called chlamydospores by the body.
