• Discovery paves the way for ultra fast high resolution imaging in real time

  Ultrafast high-resolution imaging in real time could be a reality with a new research discovery led by the University of Melbourne. In work published in Nature Communications, researchers from the University of Melbourne and the ARC Centre for Excellence in Coherent Xray Science have demonstrated th more

• Super-nanotubes: 'Remarkable' spray-on coating combines carbon nanotubes with ceramic

  Researchers from the National Institute of Standards and Technology (NIST) and Kansas State University have demonstrated a spray-on mixture of carbon nanotubes and ceramic that has unprecedented ability to resist damage while absorbing laser light. Coatings that absorb as much of the energy of high- more

• ORNL microscopy inspires flexoelectric theory behind 'material on the brink'

  Electron microscopy, conducted as part of the Shared Research Equipment (ShaRE) User Program at the Department of Energy's Oak Ridge National Laboratory, has led to a new theory to explain intriguing properties in a material with potential applications in capacitors and actuators. A research team le more

• Structural and Chemical 3D Imaging with AFM and Raman.
  

  In the Life Sciences and Bio-medical Research, the characterization of chemical compounds within cells or tissues is one of the most important and difficult tasks for researchers to perform. The development of pharmaceuticals such as drug delivery coatings or capsules also requires as much information as possible about their chemical and structural compositions. For the fields of nanotechnology and materials science, a thorough knowledge of the samples' surface morphology on a sub-micron scale is essential more

• Size and element specific determination of Ag nanoparticles in consumer spray products using asymmetric flow field flow fractionation (AF4) coupled to ICPMS
  

  The use of nanoparticles in consumer products shows a tremendous increase over the past years. A study of the Woodrow Wilson International Centre for Scholars reported that between 2005 and today the number of products based on nanoparticles increased almost twentyfold from 54 to 1015. As active compounds these products contain ZnO for surface protection, TiO2 for sun screen or Ag for anti-bacterial purposes, only to name a few applications. Furthermore, Si, C and Au are frequently used. So far, no data are available concerning the release and the behaviour of nanoparticles during the spray process. Therefore, in spite of their beneficial properties, possible risks for humans and the environment need to be thoroughly investigated. Especially the exposure pathway via the lung seems to be very critical, as could be shown in a study recently published in the Journal of Nanoparticle Research more

• IJMS, Vol. 14, Pages 10383-10396: Influence of Growth Conditions on Magnetite Nanoparticles Electro-Crystallized in the Presence of Organic Molecules

  Magnetite nanoparticles were synthesized by electrocrystallization in the presence of thiourea or sodium butanoate as an organic stabilizer. The synthesis was performed in a thermostatic electrochemical cell containing two iron electrodes with an aqueous solution of sodium sulfate as electrolyte. Th more

• Chemical Nano-Gardens: Growth of Salt Nanowires from Supramolecular Self-Assembly Gels

  In this article, we examine the phenomenon of single-crystal halide salt wire growth at the surface of porous materials. We report the use of a single-step casting technique with a supramolecular self-assembly gel matrix that upon drying leads to the growth of single-crystal halide (e.g., NaCl, KCl, more

• Linear Mesostructures in DNA–Nanorod Self-Assembly

  The assembly of molecules and nanoscale objects into one-dimensional (1D) structures, such as fibers, tubules, and ribbons, typically results from anisotropic interactions of the constituents. Conversely, we found that a 1D structure can emerge via a very different mechanism, viz, the spontaneous sy more
