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

    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.

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

    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.

  3. 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.

  4. Surface Patterning via Thiol-Yne Click Chemistry: An Extremely Fast and Versatile Approach to Superhydrophilic-Superhydrophobic Micropatterns

    Wenqian Feng, Linxian Li, Erica Ueda, Junsheng Li, Stefan Heißler, Alexander Welle, Oliver Trapp and Pavel A. Levkin

    Article first published online: 15 JUL 2014 | DOI: 10.1002/admi.201400269

    An extremely fast and initiator-free approach to create superhydrophilic-superhydrophobic micropatterns via UV-induced sequential thiol-yne click chemistry is described. The photo­patterning can be performed at room temperature in a variety of solvents, including water, and can be also used for making high-density peptide or cell microarrays.

  5. Metal–Organic Frameworks: Highly Adsorptive, MOF-Functionalized Nonwoven Fiber Mats for Hazardous Gas Capture Enabled by Atomic Layer Deposition (Adv. Mater. Interfaces 4/2014)

    Junjie Zhao, Mark D. Losego, Paul C. Lemaire, Philip S. Williams, Bo Gong, Sarah E. Atanasov, Trent M. Blevins, Christopher J. Oldham, Howard J. Walls, Sarah D. Shepherd, Matthew A. Browe, Gregory W. Peterson and Gregory N. Parsons

    Article first published online: 15 JUL 2014 | DOI: 10.1002/admi.201470023

    A new method for integrating metal-organic frameworks (MOFs) on polymer fibers is developed based on an oxide nucleation layer via atomic layer deposition (ALD). As G. N. Parsons and co-workers report in article 1400040, ALD coating enables uniform MOF coverage on fibers, high MOF loading, and large BET surface area. NH3 breakthrough tests demonstrate high adsorption capacity of the MOF-fiber mats for toxic gas. The synthesis approach is also generally applicable to a wide range of polymer fibers and MOFs. This work represents a breakthrough in the deployment of MOFs for technical applications.
