Natural occurring iron oxides, such as Fe2O3, Fe3O4, and FeO, are abundant on Earth's surface feature many implications in our daily life since the Iron Age, final epoch of prehistory humanity. The physics oxides is at frontier physical research due to their complicated magnetic electronic properties. What makes it even more intriguing introduction pressure, which not only regulates crystal str...

A new model of the medium-range ordered structure in metallic glasses is proposed. The molecular dynamics simulations revealed that there are two different types basic clusters formed glasses. One icosahedral cluster (I-cluster) around smaller-sized elements, and other Z14, Z15, Z16 Frank-Kasper (Z-clusters) bigger-sized elements. I- Z-clusters mainly connected by volume-sharing type connection...

Medium-entropy alloys (MEAs) and high-entropy (HEAs) are composed of mixtures equal or relatively large proportions three more elements, distinctly different from traditional metallic which contain one two major components with smaller amounts other elements. Recently MEAs HEAs have received extensive research attention because they found to possess superior mechanical performance, unusual ther...

production of extracellular amylase was demonstrated under conditions of high salinity in aerobically cultivated culture of a newly isolated moderately halophilic gram-positive coccus, designated strain f in basal medium containing peptone from meat, yeast extract, nacl (7% w/v) and starch. biochemical and physiological characterization along with 16s rrna sequence analysis placed f in the genu...

the radars that use medium prf, have either range ambiguity or doppler ambiguity, but these ambiguities can be resolved with selecting a prf set. avoiding ghost targets detection and minimizing blind zones are two important points that we should consider in targets detection. then, using this set, coincident algorithm and clustering the closely detected points, we resolve ambiguity and detect t...
