Graphene materials considered to be promising candidates for next-generation lubricants has been explored and summarized extensively, owing their atomic-level lamellar structure extremely low interlayer shear van der Waals barrier. However, the lubrication properties of graphene under harsh working conditions, including elevated temperature, heavy load, high vacuum, special atmosphere environment electric or magnetic field environment, have not systematically thoroughly analyzed. Meanwhile,...
Engineering nanocontainers with encapsulated inhibitors onto graphene has been an emerging technology for developing self-healing anticorrosion coatings. However, the loading contents of are commonly limited by inhomogeneous nanostructures platforms. Here, we propose activation-induced ultrathin platform (UG-BP) homogeneous growth polydopamine (PDA) benzotriazole (BTA). Ultrathin prepared catalytic exfoliation and etching activation provides ideal ultrahigh specific surface area (1646.8...
Abstract In this study, the tribological behaviors of graphene as a lubricant additive for steel/copper and steel/steel friction pairs were compared. For pair, sheets remarkably decreased coefficient wear scar depth under low loads, but these slightly increased high loads. The pair showed excellent properties even Severe plastic deformation on copper surface reduced stability tribofilm because rough transfer film steel during running-in period. results provide better understanding mechanism additive.
Abstract Impregnated graphite has attracted considerable attention and been widely used as an ideal friction material in many fields. However, the influence of temperature on its tribological properties not clearly studied; furthermore, evolution mechanism transferred tribofilm is unknown. In this study, impregnated were investigated at different temperatures, carbon-based was also determined. The results revealed that significantly improved with increase temperature. coefficient wear depth...
Abstract Although grease can effectively lubricate machines, lubrication failure may occur under high speed and heavy load conditions. In this study, Mn 3 O 4 /graphene nanocomposites (Mn #G) were synthetized using a hydrothermal method as lubricant additives. The properties of compound with #G nanocomposite additive contact loads 600–900 N (3.95–4.59 GPa) investigated. First, the dispersed into L-XBCEA 0 lithium via successive electromagnetic stirring, ultrasound vibration, three-roll...
Aqueous lubrication in nature is attracting increasing attention the tribological fields for reducing friction energy consumption and improving anti-wear durability. Generally, adding nanolubricant additives one of most important strategies to effectively enhance interface performance under boundary via formation a protective tribofilm on rubbing surfaces. However, adsorbed tribofilms are unstable prone failure during friction, interaction mechanism between frictional interfaces partly...
Reducing the friction and wear of dynamic interfaces has been a constant endeavor in field sustainability. Lubricants with two-dimensional atomic materials are operative frameworks proposed as promising candidates: they can together generate both boundary tribofilm liquid hydrodynamic film interfacial domain. However, quantitative characterization formation their coupling behaviors finite domain is lacking. Here, we report effect tribofilms films regulated by typical representatives material...
Two-dimensional (2D) nanocomposites as lubricant additives have been widely studied, but the synthetic process of is not always environmentally friendly or economical. In this study, a new 2D nanocomposite, Fe3O4/h-BN, has prepared by physical mixing exfoliated h-BN nanosheets and organically modified Fe3O4 nanoparticles. The nanocomposite displays unique 2D-layered structure without folds wrinkles. nanoparticles are uniformly dispersed on nanosheet surfaces with help an elegant...
Tuning the wettability of materials is significance in developing efficient separation materials.
Taking plant polyphenols as multifunctional platforms, we developed an environmentally friendly surface decoration strategy for preparing new types of three-dimensional (3D) superhydrophobic foams. The foams were fabricated by in situ growth β-FeOOH nanoparticles on melamine that pretreated noncovalent polyphenol–glutaraldehyde cross-linkage, followed the Michael addition 1-dodecanethiol to polyphenols. as-prepared had water contact angles 154.93° and 153.12° exterior interior surfaces,...
Size-sieving is an effective strategy for emulsion separation. However, the poly-dispersed porous nature of conventional size-sieving materials compromises their separation performances. Distinctive from materials, microporous metal–organic frameworks (MOFs) have homogeneous and uniform channels that are promising to present high porosity utilization with exceptional demulsifying capability both microemulsion nanoemulsion. internal diffusion kinetics MOFs dominate transport behaviors liquid...
Industrial manufacture generates a huge quantity of emulsion wastewater, which causes serious threats to the aquatic ecosystems. Water-in-oil (W/O) and oil-in-water (O/W) emulsions are two major types discharged by industries. However, dual separation W/O O/W remains challenging issue due contradictory permselectivity for separating emulsions. In present investigation, amphiphilicity-derived regional wetting mechanism water oil on amphiphilic collagen fibers was revealed based combination...
Kambara reactor desulfurization slag (KR slag) is a solid waste generated from the process of molten iron by KR mechanical stirring in steel factory. Most sent to landfills or stored on-site. The may be potentially used an acidic mine drainage (AMD) treatment as replacement lime due its high CaO content. This research focused on physicochemical properties samples collected corporation China and potential AMD. Two were analyzed for major minerals X-ray diffraction (XRD), particle size...
Point cloud registration is a crucial technology in the fields of robotics and computer vision. Despite significant advances point enabled by Transformer-based methods, limitations persist due to indistinct feature extraction, noise sensitivity, outlier handling. These stem from three factors: (1) inefficiency convolutional neural networks (CNNs) capture global relationships their local receptive fields, resulting extracted features susceptible noise; (2) shallow-wide architecture...
