Fabrication and Healing of Faceted Nanopores in Magnesium
نویسندگان
چکیده
Solid-state nanopores have been extensively investigated due to many biological engineering and scientific applications, such as for rapid electrical detection and analysis of biopolymers, powerful DNA detection and genome sequencing technology [1-2]. Herein, we demonstrate that faceted nanopores with various shapes can be successfully fabricated in magnesium via focused electron beam (e-beam) technology inside transmission electron microscope (TEM). Associated with orientation, the nanopore shapes varied when manipulating the e-beam irradiation direction (Figure 1). The characteristics of nanopore shapes can be explained by Wulff construction, and the crystallographic planes corresponding to the edges of nanopores are also discussed in detail [3].

We present a simple, efficient, and high-throughput methodology for the fabrication of ordered nanoporous polymeric surfaces with areas in the range of cm(2). The procedure is based on a two-stage replication of a master nanostructured pattern. The process starts with the preparation of an ordered array of poly(tetrafluoroethylene) (PTFE) free-standing nanopillars by wetting self-ordered porous...
متن کاملIn-situ Fabrication of Transparent Magnesium Aluminate Spinel by Spark Plasma Sintering
Transparent polycrystalline spinel ceramic was fabricated without any sintering aids by spark plasma sintering method of a mixture of Al2O3 and MgO powders for only 10min soak at 1250°C. Densification, microstructure and optical transparency of spinel were examined. The spinel exhibits an in-line transmission of 55% for a visible-wavelength of 470nm and high hardness value of 2040 HV.
