Transient absorption (TA) spectroscopy highlights faster electron–phonon relaxation dynamics in aggregated 40 nm nanoparticles, which is attributed to increased electron delocalization and more ...

Transition metal complexes have seen increased use in applications in the fields of photoredox catalysis, photodynamic therapy, biological sensing, and as phosphors for organic light-emitting diodes.

Abstract: To address the issue of backward wave-induced instability in traveling-wave tubes (TWTs), this letter proposes a graphene metasurface absorber (GMA) for backward wave absorption. The ...
