fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). it is well known that the structure and prope...

Fluorous protic ionic liquids (FPILS) containing a perfluorinated anion and hydrocarbon cation have been observed to segregate into nano-scale fluorocarbon, hydrocarbon and polar domains. The solubility and interactions of ethanol and butanol in a series of FPILs has been investigated by synchrotron source small and wide angle X-ray scattering. Nano-scale objects were found to be present within...

Filamentous networks can be widely found in biomaterials at the microand nano-scales. Some conventional theories may not apply to the materials with dimension at the microor nano-scale. The effects of strain gradient at the micro-meter scale and the effects of surface elasticity and initial stresses/strains at the nano-scale are incorporated into the deformation mechanisms in the analysis of st...

As we find ourselves more than one year into the pandemic, it has become apparent that many paths must be investigated to develop methods mitigate impact of pathogenic threats. While not a solution all challenges induced by interplay between communication systems and biological ones is emerging important. We, as engineers, have role play in these novel, interdisciplinary research areas. We envi...

A discussion is given of a technique to simulate the quantum mechanical motion of electrons in nano-scale devices. The results of the simulation are used to produce digital video’s, facilitating the interpretation of the quantum mechanical phenomena. The power and flexibility of the simulation method is illustrated by some examples of electron emission from nano-meter scale sources.

A simple treatment of the nano-scale MOSFET in the spirit of the Landauer approach to transport in mesoscopic structures is described. First, the essential physics is illustrated by examining numerical simulations. Next, the analytical theory of the ballistic MOSFET is discussed, and finally, the role of scattering in nano-scale MOSFETs is discussed.

In this study, the Mo-electrode thin films were deposited by a two-stepped process, and the high-purity copper indium selenide-based powder (CuInSe2, CIS) was fabricated by hydrothermal process by Nanowin Technology Co. Ltd. From the X-ray pattern of the CIS precursor, the mainly crystalline phase was CIS, and the almost undetectable CuSe phase was observed. Because the CIS powder was aggregate...

The in-situ nano-crystal-to-crystal transformation (SCCT) synthesis provides a powerful approach for tailoring controllable feature shapes and sizes of nano crystals. In this work, three nitrogen-rich energetic nano-crystals based on 5,5'-azotetrazolate(AZT2-) Cr(III) salts were synthesized by means of SCCT methodology. SEM and TEM analyses show that the energetic nano-crystals feature a compos...
