    The edge segmentation of grains in thin-section petrographic images utilising extinction consistency perception network

    The first step in petrographic image analysis is to segment the mineral grains in the thin section petrographic image, allowing the petrographer to identify the rock based on the grain size and composition. Th...

    Investigation on the thermal expansion of α-CL-20 with different water contents

    The thermal expansions of three kinds of α-CL-20 crystals have been investigated in the temperature range from 30 to 130 °C by means of various-temperature X-ray powder diffraction (XRD) together with Rietveld...

    Polyion micelles with diphase-segregated core: electrostatic self-assembly of poly(ethylene glycol)-block-poly(4-vinylpyridium) and tetrakis (4-sulfonatophenyl) porphyrin in solution

    The polyion micelles were prepared with poly(ethylene glycol)-block-poly(4-vinylpyridium) (PEG114-b-P(4-VPH+)35) and tetrakis (4-sulfonatophenyl) porphyrin (TPPS) in acid aqueous solution. Micellization was inves...
