  • Introduction to Raman Spectroscopy as a Characterization Tool for Graphene and Carbon Nanostructures
    Raman spectroscopy is a laser light scattering technique, if you like a form of vibrational spectroscopy that records vibrations of covalent bonds and provides detailed molecular information, ideal in the elucidation of carbon nanomaterials.
  • Nanoscale Biomaterials Deposition: Learning to speak the language of biology
    We invite you to join a web based discussion on new methods for patterning biological systems onto a variety of surfaces at nano- and micro-scale resolution. This will be of particular interest to bioscientists who use lithographic techniques to pattern materials to study their interactions and processes. The speakers will then answer your questions.
  • Novel Techniques for In-Situ Nanomechanical Testing in the Electron Microscope
    The combination of traditional nanomechanical test instruments with complementary techniques has generated innovative ways to characterize nanoscale materials. In particular, simultaneously pairing the high sensitivity of nanoindentation with the high spatial resolution of electron microscopy creates a powerful tool for studying nanoscale structures which are often difficult to test because of the inherent challenges imposed by the size of the samples involved. Recent developments in compact vacuum-compatible instruments which are capable of quantitative nanomechanical testing with synchronized SEM or TEM observation have spurred a number of in situ studies of nanoscale structures and helped to create a more complete understanding of their behavior.
  • In- Situ Nanomechanical Testing Techniques
    Next generation materials research is highly dependent on the development and application of innovative nanomechanical testing techniques. This webinar will cover the background and future of advanced in-situ nanomechanical characterization techniques that are becoming increasingly pertinent to research institutions and industries around the world.

  • Nanofabrication by self-assembly Nanofabrication by self-assembly
    The self-assembly paradigm in chemistry, physics and biology has matured scientifically over the past two-decades to a point of sophistication that one can begin to exploit its numerous attributes in nanofabrication. In what follows we will take a brief look at current thinking about self-assembly and with some recent examples taken from our own work examine how nanofabrication has benefited from self-assembly.
  • Nanofabrication by DNA self-assembly Nanofabrication by DNA self-assembly
    Molecular self-assembly strategies involve the formation of nanometer scale objects and materials in the absence of significant external control. One increasingly popular self-assembly approach makes use of the unique properties of deoxyribonucleic acid (DNA) including its diminutive size and high capacity for information storage. For many applications, DNA stands alone as the top choice for the programmable construction of supramolecular materials due to its specific and well-understood base-pairing interactions. In this review, we will discuss recent advances in the fabrication of materials via DNA based self-assembly.
  • Directed assembly of nanowires Directed assembly of nanowires
    Nanowires of a diverse range of compositions with tailored physical properties can be produced through synthetic means. These structures have been used as key components in flexible electronics, electronic logic gates, renewable energy technologies, and biological or gas sensing applications. Integrating these nanostructures into device or technology platforms will complement existing nanofabrication procedures by broadening the types of nanostructured materials that are utilized in device fabrication. This integration requires an ability to assemble these nanowires as controllable building blocks. Techniques are being developed that can quickly manipulate large quantities of nanowires through parallel processes.
  • Functional hybrid materials Functional hybrid materials
    Nanofabrication via self-assembly of hybrid materials into well-defined architectures is essential for the next generation of miniaturized devices. This paper describes our group's achievements towards the development of multifunctional nanostructures via self-assembly of hybrid systems based on the block copolymer PS-b-P4VP and inorganic nanoparticles (NPs) into 0D, 1D, 2D and complex 3D periodic nanostructures. The morphologies of these architectures are adjusted to gain functions via structural control at different dimensions.
