Angewandte Chemie International Edition, EarlyView.An improved low‐temperature synthesis enables the first comprehensive structural and spectroscopic characterisation of neutral hexacyanotrimethylenecyclopropane (CN6CP). Combined IR/Raman, UV–Vis and ssNMR analyses reveal a deeper understanding of its oxidation‐state‐dependent charge redistribution, σ‐aromaticity of the cyclopropane core, and redox ...

The harmonic oscillator and nuclear physics
, 1993 The three-dimensional harmonic oscillator plays a central role in nuclear physics. It provides the underlying structure of the independent-particle shell model and gives rise to the dynamical group structures on which models of nuclear collective motion ...

Reduction of the Higher Harmonic Distortion of the RC Oscillator [PDF]
A new method to reduce the harmonic distortion of the RC oscillator is presented. The output signal of the RC oscillator is delayed by π/ω and subtracted from the original signal so that the fundamental components are summed up and the second harmonic ...

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire
Advanced Physics Research, EarlyView.According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.
