TL;DR: A direct comparison with a cell deposited on the random pyramidal morphology of state-of-the-art zinc oxide electrodes, replicated onto glass using nanoimprint lithography, demonstrates unambiguously that periodic structures rival random textures.
Journal ArticleDOI
Brown carbon spheres in East Asian outflow and their optical properties
TL;DR: Using the electron energy-loss spectrum in the transmission electron microscope, the optical properties of individual, submicrometer amorphous carbon spheres that are ubiquitous in East Asian–Pacific outflow are quantified and suggest that brown carbon aerosols should be explicitly included in radiative forcing models.
Journal ArticleDOI
CsPbBr3 QD/AlOx Inorganic Nanocomposites with Exceptional Stability in Water, Light, and Heat
TL;DR: The assembly of CsPbBr3 QD/AlOx inorganic nanocomposites, by using atomic layer deposition (ALD) for the growth of the amorphous alumina matrix (AlOx), is described as a novel protection scheme for such QDs.
Journal ArticleDOI
Ripples and Layers in Ultrathin MoS2 Membranes
TL;DR: Electron microscopy shows that monolayer MoS2 displays long-range crystalline order, although surface roughening has been observed with ripples which can reach 1 nm in height, just as in the case of graphene, implying that similar mechanisms are responsible for the stability of both two-dimensional materials.
Journal ArticleDOI
A Cobalt-Iron Double-Atom Catalyst for the Oxygen Evolution Reaction.
TL;DR: Electrochemical, microscopic, and spectroscopic data including those from operan-do X-ray absorption spectroscopy, reveal a dimeric Co-Fe moiety as the active site of the catalyst.
