High quality, highly efficient finishing processes are required for difficult-to-machine materials. Magnetic abrasive (MAF) process is a method that can obtain high accuracy surface using fine magnetic particles and particles, but has poor efficiency. On the contrary, fixed polishing (FAP) material removal efficiency often cannot provide high-quality at nano-scale. Therefore, this work proposes...

In this study, the vibration behavior of functional graded (FG) circular and annular nanoplate embedded in Visco-Pasternak foundation and coupled with temperature change is studied. It is assumed that a uniform radial magnetic field acts on the top surface of the plate and the magnetic permeability coefficient of the plate along its thickness are assumed to vary according to the volume distribu...

Government regulations to address technological risks are important for the successful development and application of nanotechnology, but there is an ongoing debate in the USA about who is responsible for the regulation of nanotechnology. In a mail survey of leading US nano-scientists, we examine scientists’ perceptions about nano-regulation, including the government level (local, national, or ...

Zone plates are circular diffraction gratings that can provide diffraction-limited nano-focusing of x-ray radiation. When designing zone plates for X-ray Free Electron Laser (XFEL) sources special attention has to be made concerning the high intensity of the sources. Absorption of x-rays in the zone material can lead to significant temperature increases in a single pulse and potentially destroy...

In this study, high-energy x-ray nanotomography (nano-computed tomography, nano-CT) based on full-field microscopy was developed. Fine two-dimensional and three-dimensional (3D) structures with linewidths of 75 nm–100 nm were successfully resolved in the energy range 15 keV–37.7 keV. The effective field view ∼60 µm, typical measurement time for one tomographic scan 30 min–60 min. optical system...
