ABSTRACT We developed a novel measurement method of dielectric constant of liquids in 10-10 nm space (extended-nano space). Using our streaming potential system [1], dielectric constant was measured by regarding an extended-nano channel as an electric circuit. We revealed that the dielectric constant of water in extended-nano space was dramatically decreased (approximately 1/4 in 580 nm channel...

The minimum size of a closed nano-space in which cells can survive was determined using 4-nl nanowells. One or two cells could divide in the nanowell. Our results suggest that the cell division activity in the nano-space is determined by the conflict between intercellular effects and consumption of substrates.

Generally, a fracture is considered as an uncontrollable thus useless phenomenon due to its highly random nature. The aim of this study is to investigate highly ordered cracks such as oscillatory cracks and to manipulate via elaborate control of mechanical properties of the cracking medium including thickness, geometry, and elastic mismatch. Specific thin film with micro-sized notches was fabri...

Unlike drugs and medical devices, for which long standing and continuously improving quality assurance/quality control infrastructures exist, many nano-based products lack well-defined standards that are useful to manufacturers and regulators. Inherent variabilities in nanoparticle sizes and shapes, their large surface-to-volume ratios, and their mesoscale interactions with subcellular structur...

Sensors that change color have the advantages of versatility, ease of use, high sensitivity, and low cost. The recent development of optically based chemical sensing platforms has increasingly employed substrates manufactured with advanced processing or fabrication techniques to provide precise control over shape and morphology of the sensor micro- and nano-structure. New sensors have resulted ...

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...
