Conversion of carbon dioxide to few-layer graphene

Burning magnesium metal in dry ice forms nanosheets of graphene say US scientists. The exact mechanism for the formation of graphene is still under investigation but the team thinks that the rapid reaction kinetically favours graphene over graphite. The synthetic process is cost effective and can be used to produce few-layer graphene in large quantities.

    Read this week’s hot articles on phosphorescent OLEDs, an electrophosphorescence polymer and targeting QDs.

    Graphical abstract: Highly efficient solution-processed green and red electrophosphorescent devices enabled by small-molecule bipolar host materialHighly efficient solution-processed green and red electrophosphorescent devices enabled by small-molecule bipolar host material: A solution-processable host molecule TPO comprised of hole-transporting triphenylamine and electron-transporting oxadiazole has been synthesized by a team of Chinese scientists. The team used these materials to create a device with an efficiency of 56.8 cd A−1, which they say is among the highest ever reported for small-molecule based green phosphorescent OLED fabricated by a wet process. (J. Mater. Chem., 2011, DOI: 10.1039/C1JM10987A, Advance Article)

    Graphical abstract: An ambipolar poly(meta-phenylene) copolymer with high triplet energy to host blue and green electrophosphorescenceAn ambipolar poly(meta-phenylene) copolymer with high triplet energy to host blue and green electrophosphorescence: A conjugated polymer with a hole transporting carbazole unit and an electron transporting oxadiazole unit incorporated into a poly(meta-phenylene) backbone was prepared by scientists at the University of California, Los Angeles, USA. The carbazole unit raises the polymer’s HOMO energy level to enhance hole injection, while the oxadiazole unit lowers the LUMO energy level, to boost electron injection. The PPLED devices with PmPCz-Ox doped with green or blue phosphorescent dopants as the active layer emits exclusive phosphorescent light from the dopants. (J. Mater. Chem., 2011, DOI: 10.1039/C1JM11212K, Advance Article)

    Graphical abstract: γ-Cyclodextrin–folate complex-functionalized quantum dots for tumor-targeting and site-specific labelingγ-Cyclodextrin–folate complex-functionalized quantum dots for tumor-targeting and site-specific labeling: Chinese scientists have synthesized a series of folate-receptor targeted QDs, in which tumor-targeting folic acid was conjugated to the surface of QDs through cell-penetrated γ-cyclodextrin. The team claim that the QDs showed good optical properties and biocompatibility. (J. Mater. Chem., 2011, DOI: 10.1039/C1JM11066G, Advance Article)

    Read this week’s hot articles in Journal of Materials Chemistry

    Graphical abstract: Towards controlled synthesis and better understanding of highly luminescent PbS/CdS core/shell quantum dotsTowards controlled synthesis and better understanding of highly luminescent PbS/CdS core/shell quantum dots: A two-step cation exchange procedure for synthesizing PbS/CdS core/shell quantum dots with a much thicker shell has been developed by US and Canadian scientists. The team behind the research say this method expands the flexibility of the current cation exchange approach. These core/shell PbS/CdS QDs not only show significantly increased quantum yield of up to 67%, they are also much more photostable and thermally stable than the shell-free PbS QDs. (J. Mater. Chem., 2011, DOI:10.1039/C1JM11205H, Advance Article)

    Graphical abstract: Plasma functionalized PDMS microfluidic chips: towards point-of-care capture of circulating tumor cellsPlasma functionalized PDMS microfluidic chips: towards point-of-care capture of circulating tumor cells: An efficient and disposable microfluidic device for capturing circulating tumor cells have been created by a team of Australian scientists. The team created the device using plasma functionalization of PDMS followed by conjugation with the anti-epithelial-cell adhesion-molecule mAb. The team say that the ability to efficiently capture circulating tumor cells using a disposable, low cost PDMS device such as the one shown here should facilitate the adoption of this new technology in clinical practice. (J. Mater. Chem., 2011, DOI:10.1039/C1JM10317B, Advance Article)

    Graphical abstract: Nematic self-organization of regioselectively polyfunctionalized [60]fullereneNematic self-organization of regioselectively polyfunctionalized [60]fullerene: Fullerene hexakisadducts displaying different symmetries based on the regioselective polyfunctionalization of the fullerene sphere have been synthesised by a team at the Université de Strasbourg, France. These organic molecules could find use as organic electronic materials. (J. Mater. Chem., 2011 DOI:10.1039/C1JM10982K, Advance Article)

    The Most Read Articles in Journal of Materials Chemistry

    (In case you hadn’t already spotted this…) I thought I’d just point out that the RSC journals now have a Most Read Articles tab – it’s on the right hand side of the main journal page. The list is automatically updated everyday and shows the top 15 articles from the last 30 days.

     The most read articles page for Journal of Materials Chemistry

    At the moment the most read article is: An all-inorganic type-II heterojunction array with nearly full solar spectral response based on ZnO/ZnSe core/shell nanowires: Zhiming Wu, Yong Zhang, Jinjian Zheng, Xiangan Lin, Xiaohang Chen, Binwang Huang, Huiqiong Wang, Kai Huang, Shuping Li and Junyong Kang, J. Mater. Chem., 2011, 21, 6020-6026.
