TL;DR: The photoluminescence (PL) of silicon quantum dots present in porous silicon can be tuned from the near infrared to the ultraviolet when the surface is passivated with Si-H bonds as discussed by the authors.

TL;DR: In this paper, the exchange current density for the hydrogen oxidation/evolution reactions was determined in a proton exchange membrane fuel cell, and the transfer coefficient was found to lie within the range of 235-600 mA/cm 2 Pt and 0.5-1, respectively.

TL;DR: In this paper, the oxygen reduction reaction (ORR) kinetics of a high surface-area carbon-supported platinum catalyst (Pt/C) were measured in an operating proton exchange membrane fuel cell (PEMFC).

TL;DR: In this paper, a simplified transmission-line model with the assumption that the proton resistance and the pseudocapacitance are distributed uniformly throughout the electrode was proposed to quantify the ohmic loss in the electrode and showed that the cell voltage corrected for ohmic losses is independent of relative humidity and the electrode's I/C ratio.

TL;DR: In this paper, the maximum performance of a H 2 /oxygen proton exchange membrane fuel cell (PEMFC) for a cathode catalyst with known oxygen reduction reaction (ORR) kinetics in the absence of gas transport resistances is predicted.
