Terahertz‐Driven Ultrafast Dynamics of Rare‐Earth Nickelates by Controlling Only the Charge Degree of Freedom

open access: yesAdvanced Functional Materials, EarlyView.
The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...

Multiple Heat Exchangers Simulation Within the Newton-Raphson Framework [PDF]

open access: yes, 2002
A general framework is proposed for simulating complex heat exchanger geometries in a manner suitable for sequential solution of the refrigerant- and air-side equations for mass, momentum and energy.

High‐Entropy Magnetism of Murunskite

open access: yesAdvanced Functional Materials, EarlyView.
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.
