Interseries dipole transitions from yellow to green excitons in cuprous oxide

Trichothecenes: from Yellow Rain to Green Wheat

M ore than 20 years ago, trichothecene mycotoxins made their controversial debut on the world stage. Alexander Haig, who was U.S. Secretary of State and visiting the western sector of then-divided Berlin, alleged in 1981 that trichothecenes had been used as biological warfare agents in Southeast Asia. He cited statements from villagers in the region, who claimed that they became ill after “yell...

Theory of enhanced second-harmonic generation by the quadrupole-dipole hybrid exciton.

We report calculated substantial enhancement of the second-harmonic generation (SHG) in cuprous oxide crystals, resonantly hybridized with an appropriate organic material (DCM2:CA:PS 'solid state solvent'). The quadrupole origin of the inorganic part of the quadrupole-dipole hybrid provides inversion symmetry breaking and the organic part contributes to the oscillator strength of the hybrid. We...

Synthesis of Cuprous Oxide by Thermal Treatment in Liquid Paraffin

Cu2O nanoparticles were synthesized by thermal treatment in liquid paraffin without any inert gas protection using nano structures of Schiff base copper (II) complex (1) as precursor. Liquid paraffin was used as solvent and reductant. Span 80 was applied to control the morphology of cuprous oxide nanoparticles. The nano structure of the complex was characterized by X-ray diffraction measurement...

Consider two adolescents: Person One and Person Two. Person One has never used substances and exhibits relatively few behavioral (conduct) problems. On the other hand, Person Two uses substances frequently and more commonly exhibits poor conduct. If you were to guess, which of the individuals would you expect to have lower overall judgment and self-regulation? If you answered Person Two, your i...
