Microwave-assisted synthesis of polyoxometalate-DyO monolayer nanosheets and nanotubes.

Two-dimensional (2D) materials have shown unique chemical and physical properties; however, their synthesis is highly dependent on the layered structure of building blocks. Herein, we developed monolayer DyO-phosphomolybdic acid (PMA) nanosheets and nanotubes based on microwave synthesis. Microwave-assisted synthesis with high-energy input gives a faster and dynamically driven growth of nanomaterials, resulting in high-purity nanostructures with a narrow size distribution.

Theoretical and Experimental Study of the Spectroscopy and Thermochemistry of UC.

A combination of high-level calculations and anion photoelectron detachment (PD) measurements is reported for the UC, UC, and UC molecules. To better compare the theoretical values with the experimental photoelectron spectrum (PES), a value of 1.493 eV for the adiabatic electron affinity (AEA) of UC was calculated at the Feller-Peterson-Dixon (FPD) level.

Electronic Properties of UN and UN from Photoelectron Spectroscopy and Correlated Molecular Orbital Theory.

The results of calculations of the properties of the anion UN including electron detachment are described, which further expand our knowledge of this diatomic molecule. High-level electronic structure calculations were conducted for the UN and UN diatomic molecules and compared to photoelectron spectroscopy measurements. The low-lying Ω states were obtained using multireference CASPT2 including spin-orbit effects up to ∼20,000 cm.

Ternary hybrid CuO-PMA-Ag sub-1 nm nanosheet heterostructures.

Multi-component two-dimensional (2D) hybrid sub-1 nm heterostructures could potentially possess many novel properties. Controlling the site-selective distribution of nanoparticles (NPs) at the edge of 2D hybrid nanomaterial substrates is desirable but it remains a great challenge. Herein, we realized for the first time the preparation of ternary hybrid CuO-phosphomolybdic acid-Ag sub-1 nm nanosheet heterostructures (CuO-PMA-Ag THSNHs), where the Ag NPs selectively distributed at the edge of 2D hybrid CuO-PMA sub-1 nm nanosheets (SNSs).
