Micro-combined heat and power (CHP) holds great potential for lowering energy cost and CO2 emissions in the residential housing sector. Of the various micro-CHP technologies, fuel cells, and in particular solid oxide fuel cells, show great promise due to their high electrical efficiency and resulting low heat-to-power…
The discovery of a new family of high-T(C) materials, the iron arsenides (FeAs), has led to a resurgence of interest in superconductivity. Several important traits of these materials are now apparent: for example, layers of iron tetrahedrally coordinated by arsenic are crucial structural ingredients. It is also now we…
Excellent area-specific-resistance (ASR) values have been exhibited by cathode materials with a Sr-doped layer perovskite type structure and therefore show themselves to be possible candidates for intermediate-temperature-operating solid oxide fuel cell (IT-SOFC, 600–800°C) applications. (SBSCO) electrode was sintered…
A facile one-pot microwave irradiation reduction route has been developed for the synthesis of highly luminescent CdTe quantum dots using Na 2 TeO 3 as the Te source in an aqueous environment. The synthesis parameters of this simple and rapid approach, including the reaction temperature and time, the pH of the reactio…
Supercapacitors have emerged as attractive energy storage devices for systems requiring rapid charge-discharge cycles and high power densities. Progress in conducting polymer research for this application has shown tremendous promise due to the polymers' tendency to form highly porous films and exhibit reversible redo…
A simple trinuclear dysprosium complex shows complex slow relaxation of the magnetisation.
This tutorial review gives a brief introduction to impedance spectroscopy and discusses how it has been used to provide insight into charge transport through conducting polymers, particularly when the polymers are used as electrodes for solution studies or the design of electrodes for biomedical applications. As such…
A simple but elegant way to obtain linked donor-acceptor entities involving metallomacrocycle complexes with fixed distance and orientation is the use of coordination of axial ligands to metallomacrocycle complexes. A series of electron acceptor-bearing silicon phthalocyanine (SiPc) triads have been readily synthesize…
The development and use of functional tissue-engineered products is currently limited by the challenge of incorporating microvasculature. To this end, we have investigated strategies to facilitate vascularization in scaffold materials, in this case poly(ethylene glycol) (PEG) hydrogels. These hydrogels are hydrophilic…
Super-hydrophilicity and super-hydrophobicity are fundamentally opposite properties of special wettability, which are governed by surface chemical composition and surface roughness. Smart responsive surfaces switching reversibly between super-hydrophobicity and super-hydrophilicity can be effectively fabricated by mod…
Experimental studies of thin-film Nb- and Ta-doped TiO2 have reported that doped anatase is highly conductive, yet doped rutile is semiconducting. Standard DFT functionals (LDA, GGA) predict that for doped anatase TiO2 the excess charge occupies the bottom of the conduction band, and is delocalised over all the Ti ato…
Pulsed spray evaporation chemical vapor deposition (PSE-CVD) was employed for the synthesis of cobalt-based spinel oxide thin films, Co(3-x)Fe(x)O4 with x = 0-1.56. XRD, Raman scattering and FTIR emission spectroscopy show that the normal spinel structure was retained for 0 < or = x < or = 0.65 by the selective insert…
We consider the equilibrium behaviour and dynamics of liquid drops on a superhydrophobic surface patterned with sawtooth ridges or posts. Due to the anisotropic geometry of the surface patterning, the contact line can preferentially depin from one side of the ratchets, leading to a novel, partially suspended, superhyd…
A series of amphiphilic LC block copolymers, in which the hydrophobic block is a smectic polymer poly(4-methoxyphenyl 4-(6-acryloyloxy-hexyloxy)-benzoate) (PA6esterl) and the hydrophilic block is polyethyleneglycol (PEG), were synthesized and characterized. The self-assembly of one of them in both the pure state and t…
Polymer vesicles are stable robust vesicles made from block copolymer amphiphiles. Recent progress in the chemical design of block copolymers opens up the exciting possibility of creating a wide variety of polymer vesicles with varying fine structure, functionality and geometry. Polymer vesicles not only constitute us…
The electric-field dependence of the magnetic structure of multiferroic MnWO4 has been directly investigated using spherical neutron polarimetry as a function of temperature. The application of an electric field is shown to drive the magnetic structure to a single `chiral' domain. The magnitude of the electric field r…
Ternary Ba–Fe–As system has been studied to determine a primary solidification field of the BaFe 2 As 2 phase. We found that the BaFe 2 As 2 phase most likely melts congruently and primarily solidifies either in the FeAs excess or Ba x As 100- x excess liquid. Knowing the primary solidification field, we have performe…
Abstract First-principle electronic structure calculations have been performed in crystalline complex phases μ -Al 4.12 Mn and λ -Al 4.6 Mn using the TB-LMTO method. The atomic structures contain about 560 atoms in a large hexagonal unit cell. One of the main characteristic of their density of states is the presence o…
Ice accretion on aircraft leads to difficulties in aircraft flight control due to weight increase and change in weight distribution. Conventionally these difficulties are overcome using anti-icing or de-icing products, such as freezing depressants and heating devices. A more cost effective way to solve these problems…
This review focuses on the current trend in the commercial scale production methods of inorganic nanoparticles. The limiting factors for the scalability of synthesis methods are explained and the relationship between commercial nanoparticle materials and production methods is discussed. Particular emphasis is placed o…
