In this review, we address the materials design parameters that control the processes of charge separation, and thereby device efficiency, in dye-sensitized photoelectrochemical solar cells. The review starts with an ove...
We investigated the one- and two-photon excitation properties of a new hybrid anthracene thioxanthone (ANTX) system, which was assembled into a chevron-shaped molecular architecture. Such a geometrical association first ...
Non-noble-metal catalysts based on Fe-N-C moieties have shown promising oxygen reduction reaction (ORR) activity in proton exchange membrane fuel cells (PEMFCs). In this study, we report a facile method to prepare a Fe-N...
Different modifications of Li(x)MoO(2) (1) without metallic Mo-Mo bonds (R-3m, a = 2.858(2) angstrom, c = 15.701(13) angstrom), (2) with endless Mo chains with metallic bonds (C2/m, a = 10.614(3) angstrom, b = 2.878(1) a...
Site-selective spectroscopy in hexagonal beta-NaYF(4):Er(3+),Yb(3+) has revealed different environments for Er(3+) ions (multisite formation). The low-temperature (4)S(3/2) -> (4)I(15/2)Er(3+) green emission depends on t...
Metallic substrates are modified by a polymeric layer obtained under photochemical irradiation of acetonitrile. The reaction involves a photogenerated radical and leads to the covalent bonding of the organic layer to the...
Amorphous thin films of high-refractive index metal oxides such as Ta(2)O(5) are critical in multilayer optical components such as the main mirrors of the Laser Interferometer Gravitational-Wave Observatory (LIGO), but t...
Despite the many processes developed for carbon nanotube synthesis, few if any of these control the carbon nanotube diameter and length simultaneously. Here, we report a process whereby we synthesize vertically aligned c...
The preparation of microporous and mesoporous metal oxide materials continues to attract considerable attention, because of their possible use in chemical separations, catalyst support, chemical sensors, optical and elec...
Due to its great importance in fundamental research and practical applications, tailored synthesis of anatase TiO(2) dominated with highly energetic {001} facets has been extensively studied during the past few years. Ho...
Phosphate materials are being extensively studied as lithium-ion battery electrodes. In this work, we present a high-throughput ab initio analysis of phosphates as cathode materials. Capacity, voltage, specific energy, e...
A hybrid chemically converted graphene nanosheet/Ni(2+)/Al(3+) layered double-hydroxide (GNS/LDH) composite for supercapacitor material has been fabricated by a hydrothermal method. Scanning electron microscopy and trans...
We present a new concept of functionalizing solid surfaces using polymeric self-assembled monolayers (PSAM) that are obtained by grafting onto solid surfaces an asymmetric block copolymer composed of a long rodlike block...
