Compressively strained epitaxial (001) EuTiO${}_{3}$ thin films of tetragonal symmetry have been deposited on (001) (LaAlO${}_{3}$)${}_{0.29}$-(SrAl${}_{1/2}$Ta${}_{1/2}$O${}_{3}$)${}_{0.71}$ (LSAT) substrates by reactive molecular-beam epitaxy. Enhancement of the N\'eel temperature by 1 K with 0.9$%$ compressive stra…
Many recent applications of time-dependent density functional theory begin in an initially excited state, and propagate it using an adiabatic approximation for the exchange-correlation potential. This however inserts the excited-state density into a ground-state approximation. By studying a series of model calculation…
The non-wetting phenomena of water on certain solid surfaces have been under intensive study for decades, but the nature of hydrophobic/water interfaces remains controversial. Here a water/graphite interface is investigated with high-sensitivity atomic force microscopy. We show evidence of nucleation and growth of an…
We present an analysis of the potential thermoelectric performance of $p$-type AgGaTe${}_{2}$, which has already shown a $ZT$ of 0.8 with partial optimization, and observe that the same band-structure features, such as a mixture of light and heavy bands and isotropic transport, that lead to this good performance are p…
The dedicated small-molecule single-crystal X-ray diffraction beamline (I19) at Diamond Light Source has been operational and supporting users for over three years. I19 is a high-flux tunable-wavelength beamline and its key details are described in this article. Much of the work performed on the beamline involves stru…
Advancement of biomedical applications of carbonaceous nanomaterials is hampered by their biopersistence and pro-inflammatory action in vivo. Here, we used myeloperoxidase knockout B6.129X1-MPO (MPO k/o) mice and showed that oxidation and clearance of single walled carbon nanotubes (SWCNT) from the lungs of these anim…
ID29 is an ESRF undulator beamline with a routinely accessible energy range of between 20.0 keV and 6.0 keV (λ = 0.62 Å to 2.07 Å) dedicated to the use of anomalous dispersion techniques in macromolecular crystallography. Since the beamline was first commissioned in 2001, ID29 has, in order to provide an improved serv…

BACKGROUND: Nickel ferrite, a kind of soft magnetic materials is one of the most attracting class of materials due to its interesting and important properties and has many technical applications, such as in catalysis, sensors and so on. In this paper the synthesis of NiFe2O4 nanoparticles by the hydrothermal method is…
Abstract A facile one‐step hydrothermal method is developed for large‐scale production of well‐designed flexible and free‐standing Co 3 O 4 /reduced graphene oxide (rGO)/carbon nanotubes (CNTs) hybrid paper as an electrode for electrochemical capacitors. Densely packed unique Co 3 O 4 monolayer microsphere arrays unif…
A novel 1D/1D nanocomposite-based photodetector is successfully fabricated from high-crystalline ZnS/ZnO biaxial nanobelts for the first time. Optimized performance of the ZnS/ZnO nanobelt photodetector is much better than that of pure ZnS or ZnO nanostructures, with a wide-range UV-A light photoresponse, high sensiti…
The first use of non-centrosymmetric Janus Au-TiO(2) photocatalysts in efficient, plasmon-enhanced visible-light hydrogen generation is demonstrated. The intense localization of plasmonic near-fields close to the Au-TiO(2) interface, coupled with optical transitions involving localized electronic states in amorphous T…
Large-area MoS(2) atomic layers are synthesized on SiO(2) substrates by chemical vapor deposition using MoO(3) and S powders as the reactants. Optical, microscopic and electrical measurements suggest that the synthetic process leads to the growth of MoS(2) monolayer. The TEM images verify that the synthesized MoS(2) s…
We report on new method to obtain micrometric electroactive polymer actuators operating in air. High speed conducting Interpenetrating Polymer Network (IPN) microactuators are synthesized and fully characterized. The IPN architecture used in this work allows solving the interface and adhesion problems, which have been…
The nanocomposites of x TiO 2 + (1 − x ) CoFe 2 O 4 (where 0 ≤ x ≥ 1) were prepared using microwave–hydrothermal method at 165 °C/45 min. The as-synthesized powders were characterized using X-ray diffraction (XRD), transmission electron microscope and Fourier transform infrared spectroscopy. The particle size was foun…
Abstract The effect of Dy doping on magnetism of La 0.7 Sr 0.3 CoO 3 system was studied through the measurements of M‐T curves and M‐H curves. The results show that with Dy content increasing, T C decreases, M weakens, the coercive force strengthens, and the samples exhibit the abnormal phenomenon that M increases con…
Abstract The In 2 O 3 : W (IWO) films with different W content were deposited on glass substrate using direct current sputtering method. The structure, surface morphology, and optical and electrical properties were investigated. Results showed that both the carrier concentration and carrier mobility were increased wit…
Abstract The polyurushiol (PUS)/multiwalled carbon nanotube (MWCNT) composite coatings were prepared by in situ composite method. The fracture morphology of the composite films showed that MWCNTs had been well dispersed in PUS matrix, which significantly decreased the electrical resistivity and the gloss of the compos…
Abstract H‐terminated DLC layers were synthesized on SiO 2 substrate by radio frequency (RF) magnetron plasma‐enhanced chemical vapor deposition (PECVD) in a conventional reactor using C 4 H 10 as carbon source. As‐deposited DLC films were characterized by Raman spectroscopy, scanning electron microscopy (SEM) as well…
This review paper provides an overview of the use of hydrogen (H2) gas towards the selective catalytic reduction of nitrogen oxides (NOx) under strongly oxidizing conditions found in many industrial flue gas streams and in the exhaust emissions of diesel-powered vehicles.
