The MoS2 and MoS2/SnO2 nanocomposites were synthesized by the hydrothermal method. SEM analysis shows the flower-like structure of MoS2 while MoS2/SnO2 nanocomposites shows grain-like structure. The EDX analysis of the MoS2 and MoS2/SnO2 nanocomposites confirm the samples were mainly composed of Mo, S, Sn, and O atoms and the XRD patterns confirm hexagonal and rhombohedral phases, respectively. The FTIR spectra indicate the presence of both hydroxyl and carboxyl functional groups at the sample's surface. The UV–Visible spectroscopy findings witness both samples are being active in the visible range. Further, the band gap estimation through Tauc plot supports the assertion that these materials could be an efficient catalyst for photodegradation. Furthermore, the photodegradation of methylene blue (used as a dye) findings declare the maximum efficiency of 93% by using MoS2/SnO2 nanocomposite as a catalyst.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"36 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216531","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}

At a drive frequency of 120 Hz, the elastic modulus is found to be predominantly depth independent over the range of 100 nm to 1 μm and generally insensitive to the varying mol fraction of oxygen (0, 2, and 5%) as well as the imposed strain rates of 0.025, 0.05, and 0.1 1/s. All three SSEs exhibit significant room-temperature creep. Strain burst activity observed during loading (potentially representative of pore collapse or cracking) is attenuated with the addition of oxygen. The hardness is found to be insensitive to the imposed strain rates but varying with depth and oxygen content. The highest oxygen concentration yields the lowest hardness and strongest depth dependence.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>Nanoindentation of monolithic (oxy)sulfide glass solid-state electrolytes in an inert environment yields rate and depth dependent behavior.","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"14 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216659","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 composites are prepared by solvent casting followed by hot-pressing technique. The presence of good ferroelectric properties in the composites is confirmed by the electroactive β-phase which was found to be more than 80% in almost all the composites. The inorganic ceramic fillers improve the dielectric properties of the ceramics. The polarisation response in the composite film increases because of the interface effect between the polymer matrix and ceramic filler. The room-temperature ferroelectric hysteresis loops indicate an increase in remnant polarisation of the matrix with the concentration of filler. The energy storage density efficiency of the composites changes from 81 to 58% upon adding the ceramic filler. Piezoelectric properties of P(VDF–TrFE)–0.92(Bi0.5Na0.5)TiO3–0.08BaTiO3 composite were also investigated and found to be increased.

Although many studies have phenomenologically interpreted the formation of particles at the nanometric scale, the evolution of this field of study has focused on controlling the parameters enabling the attainment of desired morphologies and dimensions using ligands on nanoparticle surfaces. Molecules bound to nanostructured surfaces act in morphological control and aggregation processes as surface ligands transfer functional characteristics to nanostructures, which show core differences from that class of material. This study shows recent advances in nanoparticle surface functionalization with ligands either in their synthesis or in subsequent steps to modify nanoparticle surfaces. We also offer a discussion on ligand classification based on Lewis acid‒base properties and their impact on the colloidal stability of nanoparticles, enabling us to analyze the solvent‒ligand interactions that transfer characteristics from the ligand to the nanoparticle, generating flocculated or dispersed colloidal solutions.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"59 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216663","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}
