With the advent of the new media era, government social media have become an important paradigm for social governance. We perform a large-sample regression and reveal that the higher the quality of taxation bureaus' operation of government social media, the lower the degree of local enterprises'...

Single-atom catalysts (SACs) have been deemed as one of the most prospective substitutes for high-efficiency oxygen reduction reaction (ORR) catalysts due to its theoretical maximum atomic utilization. However, the convenient preparation and the further improvement in activity of SACs are...

The four well-designed porphyrin derivatives are synthesized with different electronegativity groups at the meso-substituted phenyl groups to turn the built-in electric field of the porphyrin molecules. Among them, the meso-tetrakis(meta-hydroxyphenyl) porphyrin (mTHPP) with largest diploes is...

To effectively aggrandize dielectric loss, herein, mixed-dimensional Ni foam (NF)/ZnCo2O4@NiO conductive network heterostructures consisting of three-dimensional (3D) NF, one-dimensional (1D) ZnCo2O4 nanowires and two-dimensional (2D) NiO nanosheets were designed and produced by a simple...
