The new instrument is a powerful tool that could be used in various applications in paleomagnetism such as ultrafine-scale magnetostratigraphy and single-crystal paleomagnetism.
In a recent work, SQUID microscope made it possible to use magnetostratigraphic dating as a way to image ultrafine-scale magnetic stripes related to geomagnetic reversals preserved in ferromanganese crust samples (Oda et al. 2011).
In order to realize extensive application of ultrafine-scale magnetostratigraphy of geological samples such as ferromanganese crusts for dating with a scanning SQUID microscope and pursue the possibility to improve for better resolution, sensitivity, convenience, and maintainability, we have decided to construct a scanning SQUID microscope with some new ideas.
In a presentation at the American Society of Human Genetics 2015 annual meeting, the team described how they combined genetic data, ancestry information, and electronic health records from more than 31,000 New Yorkers to identify ultrafine-scale patterns of genetic diversity within the city.
We also find that the diffuse void interface in phase-field simulation has to be treated on an ultrafine spatial scale to reproduce the void energetic characteristics and growth behavior derived from the sharp boundary approach.
Further detailed layer-by-layer microchemical analyses or Sr chemical mapping is needed to clarify the origin and distribution of Sr within the BFR because aphanitic BFR is composed of a micrometer-millimeter-scale ultrafine layering of granular and crystalline microlayers, which is much finer than the 1-cm3 scale of our sampling.
Some microstructures also contained a mixture of ultrafine or micron-scale and coarse initially cold-worked austenite grains.
A hydrothermal approach was used to prepare large-scale, aligned ultrafine bone-like apatite nanorod arrays on electrospun nylon 6 (nanofibersbers using simulated body fluid.
A new class of Al-base multi-phase ultrafine composites with multi-scale microstructure, which exhibits high strength and large compressive plasticity at ambient temperature, has been developed in the Al Cu Si ternary system.
