The exploration of new alloys with desirable properties has been a long-standing challenge in materials science because of the complex relationship between composition and microstructure. In this Research Article, we demonstrate a combinatorial strategy for the exploration of composition dependence of microstructure. This strategy is comprised of alloy library synthesis followed by high-through...
the larger benthic foraminifera gyroconulina columellifera schroeder & darmoian, 1977 (type-locality: maastrichtian aqra formation of iraq) is described for the first time from two sections of the maastrichtian tarbur formation of the zagros fold-thrust-belt, sw iran. new details on its wall microstructure are provided. the microfacies is represented by bioclastic wacke-/pack-/grainstones with ...
A theoretical model is developed to describe the formation of microstructures due plasma streaming instabilities in radially convergent geometries. Microstructures form radial spokes are found experimentally laser wakefield accelerators. The eigenvalues a set coupled linear ordinary differential equations obtained and complex wavenumbers calculated give local growth rates. predictions confirmed...
The mechanical properties of the final energetic composite depend mainly on the HTPB prepolymer microstructure; thus, the prepolymer microstructure of HTPB is one of the important factors influencing the mechanical properties of high-energy composite based on HTPB resin. In this paper, the effect of microstructure parameters of HTPB on the behavior and mechanical properties of its high-energy c...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

The aim of the study was to characterize a variety of microstructure development-levels and geotechnical property sequences of the late Pleistocene-Holocene deposits in the Mekong River delta (MRD), and the paper furthermore discusses the influences of delta formation mechanisms on them. The survey associated the geotechnical engineering and the sedimentary geology of the late Pleistocene-Holoc...
Films cast from multiphase polymer particles have the potential to combine the properties of their components synergistically. The properties of the film depend on the hybrid polymer architecture and the film morphology. However, how the polymer microstructure and particle morphology are transformed during film formation to determine the film morphology is not well understood. Here, using water...
