  1. Preparation and characterization of NaOH treated micro-fibrous polyethylene terephthalate nonwovens for biomedical application
    Afra Hadjizadeh, Abdellah Ajji, and Martin N Bureau

    J Mech Behav Biomed Mater 3(8):10 (2010) PMID 20826363

    Recently, micro-fibrous polyethylene terephthalate nonwovens have been investigated and applied in many biotechnological and biomedical applications. NaOH treatment has been used as a simple and cost effective method to alter surface properties, in order to overcome their surface ine...
  2. Dental wax impressions of plant tissues for viewing with scanning electron microscopy (SEM).
    Anke Beermann and Martin Hülskamp

    Cold Spring Harb Protoc 2010(9):pdb.prot4935 (2010) PMID 20810626

    Scanning electron microscopy (SEM) is a valuable method for examining surface structures. Taking wax impressions of plant structures, such as leaves, is a nondestructive procedure that makes it possible to view changes in surface structures over time, such as during development. This protocol descri...
  3. Discrete Functional Gold Nanoparticles: Hydrogen Bond-Assisted Synthesis, Magnetic Purification, Supramolecular Dimer and Trimer Formation
    Chun-Pong Chak, Shouhu Xuan, ... Ken Cham-Fai Leung

    ACS Nano 3(8):2129-2138 (2009) PMID 19621879

    Amine monofunctional gold nanoparticles (1-AuNPs) were synthesized by employing a solid-supported technique and pH-switchable pseudorotaxane formation. Purification was repeatedly facilitated using crown ether peripherally coated superparamagnetic iron oxide microspheres to yield the monofunctional...
  4. Surface-modified nanotube anodes for high performance organic light-emitting diode.
    Eric C-W EC Ou, Liangbing L Hu, ... George G Gruner

    ACS Nano 3(8):2258-64 (2009) PMID 19588907

    We reported high performance OLED devices with transparent and conductive carbon nanotube anodes after modification. The modifications include IMRE proprietary PEDOT:PSS composite top coating (PS(C)), concentrated HNO(3) acid soaking, and polymer encapsulation. For PS(C)-modified nanotube thin film...
  5. Multicomponent solubility parameters for single-walled carbon nanotube-solvent mixtures.
    Shane D SD Bergin, Zhenyu Z Sun, ... Jonathan N JN Coleman

    ACS Nano 3(8):2340-50 (2009) PMID 19655724

    We have measured the dispersibility of single-walled carbon nanotubes in a range of solvents, observing values as high as 3.5 mg/mL. By plotting the nanotube dispersibility as a function of the Hansen solubility parameters of the solvents, we have confirmed that successful solvents occupy a well-def...
  6. Fair and ethical trade in health procurement.
    Mahmood F Bhutta

    Lancet 372(9654):1935-7 (2008) PMID 19059038

  7. Fair trade in health supplies: a groundbreaking NHS initiative.
    Author(s) unavailable

    Lancet 372(9654):1928 (2008) PMID 19059035

  8. Injectable hydrogels as unique biomedical materials.
    Lin L Yu and Jiandong J Ding

    Chem Soc Rev 37(8):1473-81 (2008) PMID 18648673

    A concentrated fish soup could be gelled in the winter and re-solled upon heating. In contrast, some synthetic copolymers exhibit an inverse sol-gel transition with spontaneous physical gelation upon heating instead of cooling. If the transition in water takes place below the body temperature and th...
  9. Adsorption of fibrinogen on a biomedical-grade stainless steel 316LVM surface: a PM-IRRAS study of the adsorption thermodynamics, kinetics a...
    Marie-Josee Desroches and Sasha Omanovic

    Phys Chem Chem Phys 10(18):2502-12 (2008) PMID 18446250

    I bands indicated that the adsorption of fibrinogen on 316LVM results in significant changes in the protein's secondary structure that occur predominantly within the first minute of adsorption. Among the investigated structures, the alpha-helix structure undergoes the smallest changes, while the bet...
  10. Properties of shape memory polyurethane used as a low-temperature thermoplastic biomedical orthotic material: influence of hard segment cont...
    Qinghao Q Meng, Jinlian J Hu, and Yong Y Zhu

    J Biomater Sci Polym Ed 19(11):1437-54 (2008) PMID 18973722

    A series of PCL-based shape memory polyurethanes was synthesized via bulk pre-polymerization. Their thermal, mechanical properties, shape memory properties, softening and hardening processes were investigated by the experimental approach and made comparison with a commercially available orthotic mat...
