Room-temperature plasticity in metallic glasses (MGs) is commonly associated with local structural heterogeneity; however, direct observation of the subtle structural change caused by plasticity is vitally important but the data are extremely scarce. Based on dynamic atomic force microscopy (DAFM), here we show that plasticity-induced structural evolution in a Zr-Ni MG can be revealed via nano-...
Despite SiGe being one of the most widely studied thermoelectric materials owing to its application in radioisotope thermoelectric generators (RTG), the thermoelectric figure-of merit (ZT) of p-type SiGe is still quite low, resulting in poor device efficiencies. In the present study, we report a substantial enhancement in ZT∼ 1.2 at 900 °C for p-type nanostructured Si80Ge20 alloys by creating s...
This paper presents a high linearity MOSFETonly transconductor based on differential structures. While a precise BSIM4 transistor model is introduced through analysis, the linearity can be improved by mobility compensation techniques as the device size is scaled down in the nano-scale CMOS technology. When the compensation utilizes transistors in subthreshold region, rather than the transistors...
Development of nano and biotechnologies encouraged us to develop a concept of automated building, which will significantly reduce the many negative impacts of traditional construction on the environment. The paper describes the concept of Nanoto meter-scale building, a new way of building, which unfolds from the nano into the meter range. The concept is based on bionanorobots, producing buildin...
There is a limited number of methods to examine transbilayer lipid distribution in biomembranes. We employed freeze-fracture replica-labelling immunoelectron microscopy in combination with lipid-binding proteins and a peptide to examine both transbilayer distribution and lateral distribution of various phospholipids in mammalian cells. Our results indicate that phospholipids are exclusively dis...
The optical properties of various nanostructures have been widely adopted for biological detection, from DNA sequencing to nano-scale single molecule biological function measurements. In particular, by employing localized surface plasmon resonance (LSPR), we can expect distinguished sensing performance with high sensitivity and resolution. This indicates that nano-scale detections can be realiz...
In undergoing this life, many people always try to do and get the best. New knowledge, experience, lesson, and everything that can improve the life will be done. However, many people sometimes feel confused to get those things. Feeling the limited of experience and sources to be better is one of the lacks to own. However, there is a very simple thing that can be done. This is what your teacher ...
In this paper, we present superhydrophobic micro/nano dual structures (MNDS). By KOH-etching of silicon, well-designed microstructures, including inverted pyramids and V-shape grooves, are first fabricated with certain geometry sizes. Nanostructures made of high-compact high-aspect-ratio nanopillars are then formed atop microstructures by an improved controllable deep reactive ion etching (DRIE...
