Nanostructured and nanoporous metal oxide thin films are rarely accessible by standard synthetic approaches but highly desired for many applications, e.g. as electrodes, transparent conducting coatings, sensors or surface catalysts. Template based sol–gel chemistry combined with post-synthetic hydrothermal treatment allows now the synthesis of nanocrystalline mesostructured porous thin films of...

Room-temperature phosphorescence has been observed and studied on metal-activator-free mesoporous silica. The mesoporous silica was prepared using a nonionic triblock copolymer as the mesostructure-directing agent. The as-calcined products have a well-ordered porous structure and exhibit strong phosphorescence under ultraviolet light excitation. The luminescence spectra are featured with severa...

A discrete-continuous coupling analysis method based on FLAC2D/PFC2D is established with the help of program’s own FISH language and Socket O/I data transfer interface. According to statistical characteristics mesostructure slope site, computer stochastic simulation used construct model soil–rock mixture in discrete domain. The deformation failure mechanism SRM studied by using coupled method. ...

Electrolyte infiltration is one of the critical steps manufacturing process lithium ion batteries (LIB). We present here an innovative machine learning (ML) model, based on multi-layers perceptron (MLP) approach, to fast and accurately predict electrolyte flow in three dimensions, as well wetting degree time for LIB electrodes. The ML model trained a database generated using 3D-resolved physica...

Advancements in nanotechnology and materials science have led to an increased demand for specific material functions, preparation, design of polymer particles with ordered internal surface mesostructures. In this work, well-shaped spheres poly(2,2,2-trifluoroethyl methacrylate)-b-poly(2-vinylpyridine) four different molecular weights are prepared by 3D confined self-assembly. After thermal anne...

This study investigated the influence of water injection timing on compression deformation loose rock blocks in goaf. The used a confined gradient loading test to examine under initial saturation and later immersion conditions. results showed that saturation, each whole stage was greater than stage. Additionally, different stages saturated state relatively regular, while state, changed abruptly...

Traditional approaches to the formation of mesostructured inorganic films from block-copolymer and surfactant templates rely on simultaneous assembly of amphiphilic structure-directing agents and inorganic sol–gel precursor species into ordered hybrid structures. Variations in sample composition and processing conditions have afforded considerable control over the local (nanometer-scale) morpho...

A versatile photocatalyst has been prepared by grafting palladium phthalocyaninesulfonate (PdPcS) onto the FDU-14 mesopolymer with 3-D cubic mesostructure (FDU-14-PdPcS) via multi-step chemical modification processes. The FDU-14-PdPcS was characterized by the X-ray diffraction (XRD), diffuse reflectance UV-vis spectroscopy and inductively coupled plasma (ICP) techniques. In the photodegradation...
