TL;DR: The fundamental electromagnetic dynamics governing light matter interaction in plasmonic semiconductor NCs and the realization of various distinctive physical properties made possible by the advancement of colloidal synthesis routes to such NCs are discussed.

TL;DR: Results provide direct evidence of high-valent iron-oxo intermediates as the product of the first hole-transfer reaction on the haematite surface and represent an important step in establishing the mechanism of PEC water oxidation on semiconductor electrodes.

TL;DR: In this paper, the photoelectrochemical performances of Ti-doped and undoped hematite electrodes were examined and compared under water oxidation conditions, and the incorporation of Ti atoms into hematitic electrodes was found to dramatically enhance the water oxidation performance with much greater enhancement found for the thinnest films.

TL;DR: It was shown that annealing at 800 °C substantially improves the water oxidation efficiency of the ultrathin film hematite electrodes, and the effect of high temperature treatment is shown to remove one of two surface states identified, which reduces recombination and Fermi level pinning.

TL;DR: A room-temperature solution process to fabricate electrochromic films of niobium oxide glass and 'nanocrystal-in-glass' composites via acid-catalysed condensation of polyniobate clusters leads to a unique one-dimensional chain-like NbOx structure, which significantly enhances the electro chromic performance, compared to a typical three-dimensional Nb Ox network obtained from conventional high-tem temperature thermal processing.
