Temperature-Dependent Dual Fluorescence from Small Organic Molecules
The temperature-dependent dual fluorescence from a single component of small organic molecules (SOMs) is very promising for the ratiometric fluorescence sensing of temperature. However, the SOM-based fluorophores typically only show one fluorescence band.

Ground states of the XY-model on infinite one-dimensional lattice, specified by the Hamiltonian \[ -J[\sum \{(1+\gamma)\sigma_ x^{(j)}\sigma_ x^{(j)}+(1-\gamma)\sigma_ y^{(j)}\sigma_ y^{(j+1)}\}+2\lambda \sum \sigma_ z^{(j)}] \] with real parameters \(J\neq 0\), \(\gamma\) and \(\lambda\), are all determined. The model has a unique ground state for \(|

Electronic ground state of Ni2+ [PDF]
The Φ9/24 ground state of the Ni2+ diatomic molecular cation is determined experimentally from temperature and magnetic-field-dependent x-ray magnetic circular dichroism spectroscopy in a cryogenic ion trap, where an electronic and rotational temperature of 7.4±0.2 K was reached by buffer gas cooling of the molecular ion.

The role of Ta on twinnability in nanocrystalline Cu–Ta alloys
Nanostructured Cu–Ta alloys show promise as high-strength materials in part due to their limited grain growth. In the present study, we elucidate the role of Ta on the transition from deformation twinning to dislocation-mediated slip mechanisms in ...
