“…Specifically, the E’ of TPU‐GO‐2 wt % is 3731 MPa that is considerably higher than 3495 MPa of TPU‐TGO‐2 wt %—both of them are significantly higher than 3142 MPa of pure TPU. Compared with TGO, GO with more organic functional groups would provide additional interface bondings via the formation of hydrogen bonds and improved dispersion . Therefore, an improved mechanical performance is achieved in GO‐reinforced composite.…”

Despite wide applications of reduced graphene-oxide (GO)-reinforced polymer-based composites, the necessity of the reduction procedure toward GO is still controversial. In this article, thermoplastic polyurethane (TPU) composites incorporated with GO and thermally reduced graphene oxide (TGO) were fabricated. GO and TGO exhibited different effects on crystallization behaviors, and mechanical and thermal properties of the TPU matrix. With 2.0 wt % filler loading, TPU composite reinforced by GO (TPU-GO-2 wt %) exhibited better thermal stability than that reinforced by TGO (TPU-TGO-2 wt %). The interfacial interaction between the nanofillers and the TPU matrix as well as their influence on the mobility of TPU chains were investigated, which proved that GO is superior to TGO in improving interface adhesion and maintaining crystallization of the TPU matrix. Compared with TPU-TGO-2 wt %, improved mechanical properties of TPU-GO-2 wt % were also evidenced owing to more oxygen-containing groups. This work demonstrates that the reduction of GO is not always necessary in fabricating polymer composites.

“…As a result of these characteristics, SiC has become, since the 2010s, a material of choice for the manufacture of mineral membranes used in the filtration of loaded liquids (Zoubeik and Henni, 2016;Fraga et al, 2017;Sui et al, 2017;Luo et al, 2018). Indeed, these membranes are already commonly used in water purification (Zsirai et al, 2016) and wastewater treatment (Bakshi et al, 2015;He and Vidic, 2016;Kuhn et al, 2016).…”

Unfiltered wine is a turbid medium that is not generally accepted by the consumer. Therefore, one or several filtration steps are required before bottling. Silicon carbide (SiC) membranes desirable parameters (porosity, tortuosity fluxes) allow filtering several different types of loaded matrices like wine or residue sediment. An in-depth filtration study was carried out on white and red wines to evaluate membrane efficiency and to optimise their cleaning procedure. Retention rates were studied as a function of wine type, filtration mode, and volumetric concentration factor. Compared to ceramic membranes, SiC membrane permeate fluxes are higher, up to a factor of 10 for red wine. For white wines, equivalent permeate fluxes could be obtained with dead-end filtration. Moreover, SiC membranes appear to be effective in obtaining a clear and brilliant wine and do not modify the concentration of the compounds of interest in wine. Finally, an optimised cleaning protocol has been identified and shown to restore a sufficient permeability to the SiC membranes.

“…Among the porous ceramic components, beads and microspheres have been attracting great attention for the potential applications of drug carriers, adsorbents, and microreactors due to their good flowability, high packing density, and ease of separation and reuse 1–4 . Recently, porous ceramics exhibited potential in oil absorption because their relatively large specific surface area and macro‐porous structure make them have good absorption kinetics in the absorption process and plenty of oil storage space 5–9 . The characteristics of the pores in terms of porosity, pore morphology, and pore size distribution are critical factors that influence the properties of porous ceramics.…”

“…The characteristics of the pores in terms of porosity, pore morphology, and pore size distribution are critical factors that influence the properties of porous ceramics. Higher open porosity could provide more oil storage space 9 . And the decreased channel radius can enhance the absorption rate according to Laplace's law 10 .…”

Porous mullite beads with a good spherical shape and a uniform size distribution of about 1.2 mm were fabricated by ice‐templating in combination with dripping methods. These internal pore structures exhibited a radially oriented laminar channel from the center of the sphere to the surface. With the decreasing of freeze temperature to −196°C, the thickness of pore walls and the width of pore decreased. The mullite grain morphology in the pore wall was also influenced by the frozen temperature. High aspect ratio mullite grain was formed in the pore wall of beads frozen at −25°C, while low aspect ratio mullite whiskers constituted the pore wall of beads frozen at −196°C. In addition, the obtained porous mullite beads exhibited a good oil adsorption performance under capillary force for kerosene, edible oil, and motor oil with adsorption values of 3.37, 4.07, and 4.04 g/g, respectively.
