According to Young’s equation, hydrophobic/oleophilic materials are theoretically simple to realise and have a wide range of applications. The hydrophobic/oleophilic membrane, however, has a poor separating effect on the mixture in which the oil has a lower density than water. Hence, to optimise the oil/water separation performance, hydrophilic modified titanium dioxide particles were introduced to a novel porous superhydrophilic/oleophobic substrate fabricated by 3D printing technology in this work. The contact angle of n-hexadecane on the membrane surface was about 130°, which was an oleophobic surface. The oil/water separation efficiency of the 0.7 mm thick oleophobic membrane was over 98% and the penetration flux was up to 11,191 L m−2 h−1, indicating that the membranes prepared in this work might be used in high-flux oil/water separation applications. This study provides an efficient, simple, and reliable method for preparing oil/water separation materials with 3D printing technology, and may have broader significance among the academic and industry communities.KEYWORDS: 3D printingsuperhydrophilic/oleophobic membraneoil/water separationhydrophilic modificationporous structure AcknowledgementsWe would like to thank the Analytical & Testing Center of Northwestern Polytechnical University for SEM and TEM.Disclosure statementNo potential conflict of interest was reported by the author(s).Declaration of competing interestThe authors declare that they have no known competing financial interests or personal relations that could have appeared to influence the work reported in this paper.Additional informationFundingThis work was financially supported by the Fundamental Research Funds for the Central Universities [grant number 3102019PJ008 and 3102018JCC002]; National Key Research and Development Program of China [grant number 2021YFB3701500]; National Natural Science Foundation of China [grant number 52072306].","PeriodicalId":7224,"journal":{"name":"Advances in Applied Ceramics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136013534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The porous ceramsite composition of 50 wt-% of municipal sludge, 10 wt-% of municipal solid waste incineration bottom ash, 45 wt-% of waste glass powders, sintering temperature of 900°C and holding duration of 30 min. The best of the ceramsite synthesised had 1-h water absorption capacity of 51.53%, apparent porosity of 64.14% and pore volume 0.671 mL g−1. During the sintering process, the waste glass powders generated a large amount of liquid phase, wrapt the gas produced by organic matter, and formed a porous structure inside the ceramic particles. At the same time, the silica and aluminium were combined to form Kyanite, which constitutes the basic skeleton of the ceramic particles showing a certain strength. Besides, silicon oxide and calcium silicate generated Wollastonite improving the corrosion resistance of ceramic particles as well. The adsorption capacity of the prepared porous ceramsite modified by acid combined with sodium citrate was 3.1 mg g−1 using the prepared porous ceramsite as substrate. The adsorption kinetics of ammonia nitrogen by porous ceramics conforms to the quasi-second-order kinetic model, and the adsorption isotherm model conforms to the Langmuir model.

In this study, the cubic garnet Li6.25Al0.25La3Zr2O12 (Al-LLZO) was successfully synthesised by the solid-state method. The powders were uniaxially pressed and were subjected to flash sintering at 850°C in a tube furnace under a DC bias using various current densities. It is evidenced that control of the flash electric current is a crucial factor for densification of Al-LLZO. The sample sintered in 50 V cm−1 and 200 mA mm−2 showed a cubic LLZO, 94 ± 0.4% relative density, 0.37 mS cm−1 total ionic conductivity and 0.32 eV activation energy. In addition, it was demonstrated that increasing the current density had a considerable impact on the relative density. This outstanding ionic conductivity might be due to the lower lithium loss and higher density as a result of flash sintering method applied.KEYWORDS: GarnetLLZOlithium lossflash sinteringsolid-state batteries Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work is based upon research funded by Iran National Science Foundation (INSF) under project No. 4000823.","PeriodicalId":7224,"journal":{"name":"Advances in Applied Ceramics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135480732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sintering schedule of undoped as well as Zr-doped Al2O3 samples was optimised following a series of precoarsening experiments. The Zr-doped Al2O3 ceramics exhibited controlled grain size and improved density. Upon increasing the Zr-dopant concentration from 830 cat. ppm to 2070 cat. ppm. Zr-doped Al2O3 ceramics having a refined microstructure with a homogeneous distribution of controllably grown ZrO2 in Al2O3 matrix was obtained. Microhardness of the Zr-doped samples showed negligible dependence with Zr-doping, whereas mechanical strength was found to improve with it. The improvement in strength was attributed to the combined effect of improved sinter density, microstructural refinement, and grain-boundary strengthening.KEYWORDS: Al2O3ZrO2sinteringmicrostructurehardnessstrength AcknowledgementThe authors gratefully acknowledge the support of Mr Sarbapi Mukherjee, Almatis India, for the supply of alumina powders for this work.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe authors declare that the data supporting the findings of this study and supporting documents will be made available on reasonable request.","PeriodicalId":7224,"journal":{"name":"Advances in Applied Ceramics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135744615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that the creep behaviour of the two LaCoO3-based compositions was determined by ferroelastic and non-ferroelastic creep strain components. Both the ferroelastic and non-ferroelastic creep strain components showed a strong dependence on bending stress. The ferroelastic creep depends on the coercive stress in LaCoO3 based perovskites, which in turn is a function of temperature. In addition, the ferroelastic creep strain has the same sign as the total strain of cobaltites upon loading, however, it has the opposite sign relative to the total strain upon unloading. Non-ferroelastic creep was negligibly small in both perovskites at low temperatures, however, its contribution toward the total creep increased significantly at elevated temperature. Non-ferroelastic creep strain has the same sign as the total strain both upon loading and upon unloading.KEYWORDS: Perovskiteferroelastic creepnon-ferroelastic creepcoercive stressbending AcknowledgementsDr. Lugovy’s work at Empa was supported by Swiss National Science Foundation via the Scientific Exchanges grants (proposal MENDEL).

Two different types of microstructure were designed, one consisting of separated alumina inclusions in a zirconia matrix and another one which was a combination of two continuous phases, penetrating the whole volume of the composite. It was detected that at elevated temperatures both materials showed a distinct decrease in the wear rate. Composite with a low alumina content showed minimal wear rate at 300°C and composite with higher amount of alumina showed it at 400°C. There are some observations that this minimal wear rate result is connected with a pseudoplastic behaviour of a layer formed between co-operating elements of tribological pair. This layer is composed of the debris of both, sample and counterpart, and its behaviour during sliding is connected with the mean grain size of this debris which is correlated with the mean grain size of sintered material.KEYWORDS: Alumina toughened zirconiaTribologySliding wearBall-on-disc test Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was supported by subvention of the Polish State Ministry of Education and Science for AGH University of Science and Technology under projects 16.16.160.557 and 16.16.130.942.

Various surface engineering techniques have been developed for steels, among which chromizing is an affordable high-throughput case-hardenig process for improved surface hardness and wear resistance while retaining the substrate ductility and toughness. In this work, tribological testing along with nano- and micro-indentation and morphological and composional characterisation were used to understand the effects of the chromizing process on the AISI 1095 carbon steel, 52100 bearing steel and A2, D2 and M2 tool steels. The results of this study demonstrate that the chromizing treatment of low-cost 1095 and 52100 steels significantly improves their wear and hardness properties to a level comparable to the more costly tool steels. While chromizing also increased the hardness of the tool steels, it had little improvement on the wear resistance for the D2 and M2 tool steels.KEYWORDS: Case chromizingsteelabrasive wearnanoindentation AcknowledgementsThe authors would like to thank Jim Keiser from Oak Ridge National Laboratory (ORNL), Oyelayo O.
