“…Table 1 shows the contact angle (θ) for the hybrid's acrylic polymer on the right and left as well as the average contact angle. demonstrating that the fabric surface roughness values dropped dramatically, which agrees with [19]. We discovered a roughness of 2.73-1.22 µm in a pure sample of acrylic polymer and a 2 wt% of GR.…”

In this framework, a polymeric coating was enlarged by integrating graphene (GR) and chopped carbon fibers (CF) into the polymer mixture to be utilized for the waterproof coatings and exterior floor. The polymeric hybrid coatings were made by casting a combination of acrylic polymer, and GR, or GR-CF at room temperature. The polymer hybrids were composed of different ratios (0.25, 0.5, 1, and 2 wt%) of GR or GR-5wt% CF. The morphology, thermal stability, roughness, and the contact angle of the prepared polymer hybrids were investigated. The roughness of the fabric surface was found to be greatly reduced as the weight ratio of GR or GR-5wt% CF increased. The greatest contact angle was determined to be 83.07° for samples containing 2% GR-5wt% CF, whereas the least roughness was recorded for 2% GR and equals 1.22 µm. The addition of CF to polymers hybrid increased the roughness and contact angle. Thermal stability was improved as the weight ratio of GR, and GR-5wt% CF was increased. The maximum value of the impact strength was observed for acrylic polymer containing 1% GR-5wt% CF. The hardness of Shore A was steadily increased with increasing GR or GR-5wt% CF in the hybrid’s polymer. The presence of GR or GR-CF in the formed hybrids polymers has resulted in an improvement in the mechanical properties, wettability, thermal stability, and hydrophobicity, and hence might be employed for waterproofing coatings.

“…However, water, food and clothing waste emerged as a very important problem in all age groups in the present research. Studies on waste have also emphasized that education, social norms, and pro-environmental behaviors are important in preventing waste [74,77,[80][81][82][83][84][85][86][87].…”

While people consume natural resources by interacting with the environment, they also cause some environmental changes. Environmental pollution and construction are among the most important reasons for these changes. In addition, the rate of renewal of natural resources remains slow while consumption is increasing. Thus, biocapacity is slow to renew itself compared to consumption, leading to the emergence of an ecological deficit. The largest share in the ecological deficit belongs to personal consumption. Based on this, the attitudes and behavior of individuals in Turkey to reduce their ecological footprint were examined in the context of ecological sustainability. The survey model was adopted in the study. The data collected from 773 people via the scale and various forms were analyzed. The results of the analysis show that the ecological footprint size in Turkey is above the world average in personal consumption. It has been determined that the participants have significant behavioral deficiencies in the behaviors towards reducing the ecological footprint, such as recycling, reusing the product by repairing, composting, not wasting water, food and clothing, and they tend to use packaged products excessively.

“…The surface roughness of GR laminated systems can affect numerous functi properties [38,39]. That is why the following parameters were analyzed here: Ra-an a metic mean deviation of the C atom positions from the average height value; Rmax-a m imum relief height, e.g., the difference between the maximum and minimum heigh The calculated surface roughness parameters of GR/Ni systems for different substrate orientations and temperatures are summarized in Table 2.…”

The effect of graphene (GR) on Ni surface relaxation and reconstruction in three different substrate orientations, {111}, {001}, and {011}, at two different temperatures, 300 K and 400 K, was studied using molecular dynamics simulation. The change in the interplanar distances of the substrate and redistribution of Ni and C atoms in a direction perpendicular to the surface was compared with the equilibrium state of GR and bulk Ni, in the absence of the counterpart. The surface reconstruction for the GR/Ni system was analyzed based on the calculated radial pair distribution functions of Ni and C atoms. The surface roughness was visualized using 2D atomic distribution maps. The introduction of GR on the Ni surface in any crystallographic orientation decreases the maximum modification of interplanar spacing compared to the bulk by less than 1%. For the studied substrate orientations and temperatures, it was found that the most densely packed {111} orientation of the Ni base provides minimal changes in the structural parameters of both counterparts at 400 K. Additionally, the system formed by GR deposition on Ni {111} at 400 K is characterized by the least roughness.
