Localized surface plasmon effects on the photophysics of perovskite thin films embedding metal nanoparticles [PDF]

open access: yes, 2020
Herein we provide direct experimental evidence that proves that the photophysical properties of thin methylammonium lead iodide perovskite films are significantly enhanced by localized surface plasmon resonances (SPRs). Observations are well supported by

Self-propelled rods exhibit a novel phase-separated state characterized by the presence of active stresses and the ejection of polar clusters [PDF]

open access: yes, 2015
We study collections of self-propelled rods (SPR) moving in two dimensions for packing fractions less than or equal to 0.3. We find that in the thermodynamical limit the SPR undergo a phase transition between a disordered gas and a novel phase-separated ...
