Free-standing films based on a plasma-exfoliated multi-layer graphitic material composite comprising polyelectrolyte and fluorosurfactant. Such materials show oleophobic/hydrophilic properties application within oil–water separations.
We have developed a solvothermal reduction method that affords more effective reduction of chemically derived graphene sheets and graphite oxide than low-temperature reduction methods. Solvothermal reduction removed oxygen and defects from graphene sheets, increased the size of sp(2) domains, and produced materials that were as conducting as pristine graphene and exhibited clear intrinsic Dirac...
The anisotropic thermal conductivity of passivated black phosphorus (BP), a reactive two-dimensional material with strong in-plane anisotropy, is ascertained. The room-temperature thermal conductivity for three crystalline axes of exfoliated BP is measured by time-domain thermo-reflectance. The thermal conductivity along the zigzag direction is ≈2.5 times higher than that of the armchair direct...
• Exfoliation of layered stannosilicate greatly increases its catalytic performance. In sucrose conversion, the exfoliated catalyst shows a methyl lactate yield approximately 50 %. Exfoliated is active after several reaction cycles. Biomass has been shown as an alternative to fossil fuels for obtaining chemicals. this work, transformation sugars into (ML) at 160 °C was carried out using UZAR-S3...
We have developed methods to exfoliate MoS 2 in large quantities in surfactant-water solutions. This method can be extended to a range of other layered compounds. The layered material tends to be exfoliated as relatively defect free flakes with lateral sizes of 100s of nm. in layered crystals and can be metals, semiconductors or insulators. [1] In addition, some are thermoelectric materials, [2...
Cost-effective storage remains one of the greatest challenges facing adoption renewable energy generation. Herein we present a cost-effective aqueous rechargeable battery based on MoS2. Increased discharge capacities are achieved by liquid-phase exfoliation, resulting in 105% increase capacity and prolonged lithiation plateau. Contributing evidence is provided High Resolution TEM investigation ...
Background: This study aimed to evaluate the diagnostic value of outer dense fiber 4 (ODF4), melanoma-associated antigen A3 (MAGEA3), and MAGEAB4 mRNAs in transitional cell carcinoma (TCC), using a small amount of cell reverse transcriptase-polymerase chain reaction (RT-PCR) on urinary exfoliated cells. Methods: We recruited a total of 105 suspected TCC patients and 54 sex- and age-matched non-...
Oil spills are the most important environmental impact in oceans and seas. In this article, Oil absorption, which was explored from Sardar-e-Jangal oilfield in Caspian Sea, by exfoliated graphite (EG), was investigated. Graphite was exfoliated through the reaction of graphite-CrO3 intercalation compounds with hydrogen peroxide. The obtained absorbent was characterized by Brunauer-Emmett-Teller ...
