Hydroxylated metal–organic-layer nanocages anchoring single atomic cobalt sites for robust photocatalytic CO2 reduction
Assembly of two-dimensional (2D) metal–organic layers (MOLs) based on the hard and soft acid–base theorem represents an exquisite strategy for the construction of photocatalytic platforms in virtue of the high...

Energy-dispersive X-ray Spectroscopy for the Quantitative Analysis of Pyrite Thin Specimens
To explore ways to improve the accuracy of quantitative analysis of samples in the micrometer to nanometer range of magnitudes, we adopted analytical transmission electron microscopy (AEM/EDS) for qualitative ...

The Correlation Between Molecular Structure and Tribological Properties of Graphene Oxide with Different Oxidation Degree
Eight kinds of GOs with different oxidation degree were synthesized. Molecular structure characterization indicated that with more usage of H2SO4, less usage of KMnO4, and more reaction time at high temperatures ...

Open AccessTuning the Optical Properties of CsPbBr3 Nanocrystals by Anion Exchange Reactions with CsX Aqueous Solution
Topotactic anion exchange has been developed to tune the composition and band gap energies of cesium lead halide (CsPbX3) perovskite nanocrystals (NCs). However, current anion exchange methods either require hars...

Adhesion-dependent negative friction coefficient on chemically modified graphite at the nanoscale
Classically, friction is known to increase with increasing normal load. Scanning probe experiments now show that reversible local delamination of chemically modified graphite can lead to an enhancement in fric...

Open AccessSynthesis and Characterization of Bowl-Like Single-Crystalline BaTiO3 Nanoparticles
Novel bowl-like single-crystalline BaTiO3 nanoparticles were synthesized by a simple hydrothermal method using Ba(OH)2·8H2O and TiO2 as precursors. The as-prepared products were characterized by XRD, Raman spectr...
