The phase of graphene plasmon upon edge-reflection plays a crucial role on determining the spectral properties of graphene structures. In this article, by using the full-wave simulation, we demonstrate that the mid-infrared graphene plasmons are nearly totally reflected at the boundary together with a phase jump of approximately 0.27π, regardless of the environments surrounding it. Appling this...

The properties of metallic clusters of various shapes, on the nanometer length scale, can be dramatically different from the corresponding bulk material due to their very large surface-to-volume ratio. The unique optical and mechanical properties of such nanoclusters hold great promise for the development of nanotechnology. Gold nanoclusters, for example, have found application in such diverse ...

We propose a hybrid nano-structuring scheme for tailoring thermal and thermoelectric transport properties of graphene nanoribbons. Geometrical structuring and isotope cluster engineering are the elements that constitute the proposed scheme. Using first-principles based force constants and Hamiltonians, we show that the thermal conductance of graphene nanoribbons can be reduced by 98.8% at room ...

Since its first realization by Crewe et al. in the late 60s, the STEM microscope design has fully confirmed its potentiality for capturing most signals resulting from the interaction between a primary electron beam and the target. Taking benefit of recent instrumental developments, it now offers unique performance in terms of joint spatial and spectral resolution. The richness of this multi-sig...

Policy makers from around the world are trying to emulate successful innovation systems in order to support economic growth. At the same time, innovation governance systems are being put in place to ensure a better integration of stakeholder views into the research and development process. In Europe, one of the most prominent and newly emerging governance frameworks is called Responsible Resear...

While fracture is generally considered to be undesirable in various manufacturing processes, delicate control of fracture can be successfully implemented to generate structures at micro/nano length scales. Fracture-based fabrication techniques can serve as a template-free manufacturing method, and enables highly-ordered patterns or fluidic channels to be formed over large areas in a simple and ...

Superior first-cycle Coulomb efficiency (above 80%) is displayed by filter paper-derived micro-nano structure hard carbon, and it delivers a high reversible capacity of 286 mAh g-1 after 100 cycles as the anode for Na-ion battery at 20 mA g-1. These advantageous performance characteristics are attributed to the unique micro-nano structure, which reduced the first irreversible capacity loss by l...
