The main wear mechanism in the nanocomposite was abrasion of the ceramic and carbon components which act in the interface as a sort of lubricating media. The experimental results demonstrate that the addition of CNFs to the ceramic composites significantly reduces friction coefficient and wear rate, resulting in suitable materials for unlubricated tribological applications.

Oxidative Dehydrogenation of Ethylbenzene Over Poly(furfuryl alcohol)-Derived CMK-1 Carbon Replica

“…These materials exhibit a significant contribution of well-ordered mesopores, which act as wider transport channels for reagents and reduce the diffusion limitations. The main concept of synthesis of OMCs is based on replication of structure of a soft or hard template using a carbon precursor [15]. The soft templating technique includes mixing of a carbon precursor and a pore forming agent (surfactant) to induce the self-assembly process of molecules into micelles generating 3-D structures.…”

Engineered Magnetic Carbon-Based Adsorbents for the Removal of Water Priority Pollutants: An Overview

“…XPS helps to identify the functional states of elements and their chemical bonds on the adsorbent surface [112]. N 2 adsorption/desorption isotherms give information about the adsorbent textural parameters (i.e., surface area, porosity distribution, and pore volume) [113]. Magnetometry measures the magnetic properties like magnetic moment, permeability, and saturation magnetization.…”

WPU/CB/GO nanocomposites: in situ polymerization preparation, thermal, and anticorrosion performance evaluation

“…Ideally, according to the prediction of generalized Maxwell model, adding a small amount of packing into polymer matrices can remarkably perfect the performance of the composite material . During the past few decades, carbonaceous material with multifarious physical, chemical, and structural characteristics has received increasing attention . One of them, carbon black (CB), has been widely applied to prepare composites on account of its strong reinforcement and easy dispersibility .…”

“…7 During the past few decades, carbonaceous material with multifarious physical, chemical, and structural characteristics has received increasing attention. 8 One of them, carbon black (CB), has been widely applied to prepare composites on account of its strong reinforcement and easy dispersibility. [9][10][11][12][13] Moreover, researchers have attached great importance to graphene and its family, 14 especially graphene oxide (GO).…”
