網頁For all his work, the 1905 Nobel Prize in Physics was awarded to Philipp Eduard Anton von Lenard “for his work on cathode rays”, but not for the photoelectric effect. Ironically, it was also in 1905 that Albert Einstein, building upon Planck’ theory of quanta, formulated his deceptively simple, but revolutionary disruptive theory of the photoelectric effect … tre rj pje 2 grau網頁2024年3月28日 · Herein, a new MXene and Bi (MXene/Bi) composite material is first applied as the (de)intercalation cathode of ZIB. The dispersed MXene nanosheets in the composite materials greatly improve the conductivity and hydrophilicity of the electrode, and prevent the stacking and the volume expansion in the charge/discharge process of 2D Bi fragments. tre rivali mke網頁The organic photoelectric conversion layer is configured to absorb light in at least a portion of a wavelength spectrum of incident light and to convert the absorbed light into an electrical signal. The charge auxiliary layer includes a metal and an oxide. tre rn dje網頁For the cathode, a vertical flat electrode was changed into a micro-nano surface electrode to investigate the influence of micro-nano structures on the AWE performance in this study.
