  • Nanomechanical characterization of the most challenging soft materials
    CSM Instruments is pleased to announce our webinar entitled "Nanomechanical characterization of the most challenging soft materials". This is presented in partnership with Materials Today (Elsevier) and is scheduled on September 29th. Characterization of soft materials such as polymers, elastomers gel or cell by indentation has always been a challenging task because these materials show almost always time dependent mechanical properties. Their visco-elastic properties are characterized by storage and loss moduli whereas response of the material to constant load is described by its creep properties. Since these properties are time dependent, the use of experimental techniques with perfect thermal stability is required so that the results are not discredited by the inherent error of the measurement technique. The most important source of errors in indentation is phenomenon called thermal drift, i.e. change in displacement signal while constant load is applied on a thermally stable material such as fused silica.

  • Graphene single-electron transistors Graphene single-electron transistors
    Graphene, a single layer of carbon atoms forming a perfectly stable and clean two-dimensional crystal with very few defects, has been proclaimed to be a new revolutionary material for electronics. These hopes rest mainly on the unique band structure properties of graphene.

  • Resonance properties of metallic ring systems Resonance properties of metallic ring systems
    We review our recent efforts in understanding the resonance properties of metallic ring systems using a rigorous mode-expansion theory. In the quasi-static limit, we established a matrix-form circuit equation to calculate the frequencies and current distributions for all resonance modes in a ring system. We then applied the theory to study different split ring resonators (SRR).
  • Electromagnetic wave in 2D photonic crystals Electromagnetic wave in 2D photonic crystals
    In this article, we have reviewed recent progresses on the negative refraction and the abnormal transmission of electromagnetic wave in two-dimensional photonic crystals. The physical mechanisms related to these phenomena have been analyzed, and the focusing properties of the point source through the photonic-crystal-based flat lens have been discussed.
