Actinide tetra-N-heterocyclic carbene ‘sandwiches’

Description: Article preparing highly-symmetrical, thorium and uranium octakis-carbene ‘sandwich’ complexes by ‘sandwiching’ the An(IV) cations between two anionic macrocyclic tetra-NHC ligands. The complexes are characterized by a range of experimental methods and DFT calculations.

Energy Conversion During Expansion of a Solid-Particle-Entrained Gas

Description: This article describes pneumatic energy being converted into solid particle kinetic energy as a solid-particle-entrained gas that flows downward through a vertical nozzle. For the conditions studied, the solid particles serve as a heat exchange medium to enable a gas expansion that is nearly isothermal. Also, the kinetic energy associated with the two-phase fluid is predominantly that associated with subsonic solid-particle motion. The kinetic energy of the solid particles is converted into oth… more

Generation of over 1000 Diffraction Spots from 2D Graded Photonic Super-Crystals

Description: Discusses a project in which researchers were able to generate over 1000 diffraction spots from a graded photonic super-crystal with a unit super-cell size of 12a × 12a where a is the lattice constant and hole radii are gradually changed in dual directions.
