    Strongly coupled interfaces between conductive hosts and sulfur-containing guests: a chemical gradient is built to adsorb polar polysulfides and allow facile deposition of recharged Li2S by electron-rich pyridinic nitrogen and a carbon surface around the quaternary nitrogen. Therefore, the nitrogen-doped carbon nanotubes exhibit a remarkably improved lithium storage performance in lithium-sulfur batteries.

  2. Boron Nitride Nanosheets for Metal Protection

    Boron nitride nanosheets have desirable properties of metal protection against oxidation and corrosion, without causing galvanic corrosion as in the case of graphene

  3. Highly Intensified Surface Enhanced Raman Scattering through the Formation of p,p′-Dimercaptoazobenzene on Ag Nanoparticles/Graphene Oxide Nanocomposites

    Hong-Yi Wu, Ying-Huang Lai, Meng-Shan Hsieh, Shiau-Dan Lin, Yen-Cheng Li and Tsung-Wu Lin

    Article first published online: 17 JUL 2014 | DOI: 10.1002/admi.201400119

    The reversible conversion between 4-aminothiophenol and p,p′-dimerc­aptoazobenzene is performed with a single Ag nanoparticles/graphene oxide nanocomposite (AgNPs/GO) via the assistance of local surface plasmon. The formation of p,p′-dimercaptoazobenzene on AgNPs/GO leads to the decrease in distance between adjacent AgNPs on GO surface, enhancing the local electromagnetic field near AgNPs. This effect is beneficial to enhancing surface Raman enhanced scattering signals of Rhodamine 6G molecules.

  4. Multi-Modal, Surface-Focused Anticoagulation Using Poly-2-methoxyethylacrylate Polymer Grafts and Surface Nitric Oxide Release

    Surbhi Gupta, Kagya A. Amoako, Ahmed Suhaib and Keith E. Cook

    Article first published online: 17 JUL 2014 | DOI: 10.1002/admi.201400012

    This study examines the combination of protein-adsorption-resistant coatings along with nitric oxide (NO) release to reduce biomaterial surface platelet adhesion. On polypropylene, platelet adhesion significantly decreases due to both NO release and coating with poly-2-methoxyethylacrylate. The combination of the two, further causes a significant decrease. This combined approach thus holds promise for extending the lifespan of blood-contacting devices.

  5. Enhancement of the Grain Boundary Conductivity in Ceramic Li0.34La0.55TiO3 Electrolytes in a Moisture-free Processing Environment

    Frederic Aguesse, Juan Miguel López del Amo, Vladimir Roddatis, Ainara Aguadero and John A. Kilner

    Article first published online: 17 JUL 2014 | DOI: 10.1002/admi.201300143

    The use of moisture-free environments (<2ppm) for the processing of dense Li0.34La0.55TiO3 has been demonstrated to be an effective approach to avoid the corrosion process that promotes the formation of Li2CO3 as secondary phase in the grain boundaries and surfaces. This leads to and improvement of the microstructure of dense ceramics and to an increment of 5 times in the total conductivity.
