Ultrahigh molecular weight polyethylene (UHMWPE) materials have been prevalent joint replacement materials for more than 45 years because of their excellent biocompatibility and wear resistance. In this study, functionalized activated nanocarbon (FANC) was prepared by grafting maleic anhydride polyethylene onto acid-treated activated nanocarbon. A novel porous UHMWPE composite was prepared by incorporating the appropriate amount of FANC and pore-forming agents during the hot-pressing process for medical UHMWPE powder. The experimental results showed that the best prepared porous UHMWPE/FANC exhibited appropriate tensile strength, porosity, and excellent hydrophilicity, with a contact angle of 65.9°. In vitro experiments showed that the porous UHMWPE/FANC had excellent biocompatibility, which is due to its porous structure and hydrophilicity caused by FANC. This study demonstrates the potential viability for our porous UHMWPE/FANC to be used as cartilage replacement material for biomedical applications.

“…This measure allows several times to reduce the volume of dust emissions into the atmosphere, which significantly reduces environmental risks for residents of the adjacent territories. Due to the rotational movement of the irrigation system plates, dust particles coagulate both on the surface of these plates, as well as when gas passes through the holes [17]. Rotary movements of the coagulation plates completely exclude the possibility of dry non-irrigated areas, preventing the adhesion and accumulation of dust particles on the plates, and also contribute to the dispersion of the liquid into more fractional drops, eliminating the possibility of subsequent occurrence of direct-flow jet streams.…”

The purpose of research work should be considered the practical aspects study of environmental pollution near highways with dust particles generated during repair work. The results of the study reflect the entire scope of research work carried out in order to determine the optimal composition of the concrete mixture for road repair work, which makes it possible to achieve a reduction in the emission of dust particles into the roadside environment and improve the environmental situation in the roadside. Also in this study, recommendations were proposed for the elimination of polluting factors and the elimination of negative consequences for the environment. The results and conclusions of this scientific study are of significant practical importance for road maintenance workers who professionally solve the issues of pavement repair, as well as for researchers conducting scientific research in the direction of studying environmental safety problems during road repair work.

Superhydrophobic surfaces applying on concrete can greatly improve the durability of concrete by preventing the damage from water. However, traditional design of superhydrophobic concrete surfaces by external coating encounters to problems of flaking and poor surface robustness, while that by adding hydrophobic agents or particles faces the challenges of strength damage of concrete. Drawing inspiration from the carbonation phenomenon of concrete, here a new design of in situ growing superhydrophobic structures on concrete is proposed: The concrete sample is impregnated into Mg2+‐containing silane–water system with continuous CO2 injection. The contact angle of the concrete surface achieves 171.9° without obvious strength decrease after 120 min, which are mainly attributed to the formation of CaxMg1−xCO3 crystals with micro‐nano‐structures and the reduction of carbonates surface energy by silane. This superhydrophobic concrete structure can be divided into a superhydrophobic–hydrophobic–hydrophilic three layers structure, providing the stable water‐proof protection under mechanical fatigue, capillary water absorption, UV aging, sulfate attack, and impurity water impact tests due to the in situ growing robust superhydrophobic structures. Furthermore, it captures 29.80 g m−2 CO2 during the reaction process, providing new insights for the design and preparation of eco‐friendly superhydrophobic concrete.
