It is desirable for textiles to prevent static charges and to repel water. This work used nano-silver antistatic finish and fluorine water-repellent finish in order to determine whether it is possible for antistatic and water-repellent properties to coexist on a single sample of polyester fabric. The antistatic and wa…
The device physics and electro-optical properties of emerging liquid crystal displays (LCDs) based on the Kerr effect are investigated. With a voltage applied, both blue phase and polymer-stabilized blue phase exhibit a fascinating isotropic-to-anisotropic transition. We have developed a numerical model to understand…
The introduction of single-site catalysts in the polyolefins industry opens new routes to design resins with improved performance through multicatalyst-multireactor processes. Physical combination of various polyolefin types in a secondary extrusion process is also a common practice to achieve new products with improv…
Textile manufacturing is one of the largest industries in the world, and synthetic fibres represent two-thirds of the global textile market. Synthetic fibres are manufactured from petroleum-based feedstocks, which are becoming increasingly expensive as demand for finite petroleum reserves continues to rise. For the la…
Abstract BACKGROUND: Magnesium hydride is considered to be a promising hydrogen storage material because of its high gravimetric and volumetric storage capacities. However, its slow kinetics and high desorption temperature of > 300 °C limit practical applications. In this work, TiC nanoparticles were selected to mo…
AIMS: Single-walled carbon nanotubes (SWNTs) are likely to become increasingly widespread and yet their environmental impact is not well understood. The purpose of the current study was to evaluate the impact of SWNTs on microbial communities in a 'sentinel' environmental system, activated sludge batch-scale reactors.…
BACKGROUND: The halophilic archaeon Haloferax mediterranei is able to accumulate large amounts of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with high molar fraction of 3-hydroxyvalerate (3HV) from unrelated carbon sources. A Polyhydroxyalkanoate (PHA) synthase composed of two subunits, PhaCHme and PhaEHme, h…
Three new compounds (enH)(6+n)Cu(40)Sn(15)S(60) (1), (enH)(3)Cu(7)Sn(4)S(12) (2), and (trenH(3))Cu(7)Sn(4)S(12) (tren = tris(2-aminoethyl)amine) (3) containing Cu(8)S(12) and Cu(7)SnS(12) clusters have been prepared from direct solvothermal reaction of the elements in amine solvents. In 1, the cubic close-packed arran…
Uniaxial magnetic anisotropy has been observed in La0.7Sr0.3MnO3 thin films grown on top of multiferroic BiFeO3 with ferroelectric stripe domains (see Figure). The magnetic easy axis of La0.7Sr0.3MnO3 correlates with the ferroelectric stripe domains. A possible spin coupling model at the La0.7Sr0.3MnO3/BiFeO3 interfac…
Abstract Cycling of deepwater silicon (Si) within the Southern Ocean, and its transport into other ocean basins, may be an important player in the uptake of atmospheric carbon, and global climate. Recent work has shown that the Si isotope (denoted by δ 29 Si or δ 30 Si) composition of deep sea sponges reflects the ava…
On the basis of static and dynamical density functional theory, a phase-field-crystal model is derived which involves both the translational density and the orientational degree of ordering as well as a local director field. The model exhibits stable isotropic, nematic, smectic A, columnar, plastic-crystalline and ori…
Here, we report a unique design strategy to trace the role of aromatic π-stacking and van der Waals interactions on the molecular self-organization of π-conjugated building blocks in a single system. A new series of bulky oligophenylenevinylenes (OPVs) bearing a tricyclodecanemethylene (TCD) unit in the aromatic π-cor…
Abstract Polyaniline (PANI) is a well‐studied material and is the pre‐eminent electrically conducting organic polymer with the potential for a variety of applications such as in batteries, microelectronics displays, antistatic coatings, electromagnetic shielding materials, sensors and actuators. Its good environmental…
The strength and distribution of Brønsted acidic protons in anhydrous phosphomolybdic acid (H 3 PMo 12 O 40, HPMo) have been studied by solid-state magic-angle-spinning (MAS) NMR, using trimethylphosphine oxide (TMPO) as the probe molecule in conjunction with density functional theory (DFT) calculations. Brønsted acid…
In a recent publication (Hansen-Goos and Mecke 2009 Phys. Rev. Lett. 102 018302) we constructed a free energy functional for the inhomogeneous hard-body fluid, which reduces to Rosenfeld's fundamental measure theory (Rosenfeld 1989 Phys. Rev. Lett. 63 980) when applied to hard spheres. The new functional is able to yi…
Meso-tetrasubstituted Mg(II) porphyrins containing six membered phenyl groups (MgTPP) and five membered thienyl (MgTThP) and furyl groups (MgTFP) were synthesized and structurally characterized, and the effects of meso-substituents on electronic properties were studied using NMR, absorption, fluorescence spectroscopy,…
Deadly cerias: The decomposition of organics in a CeO2/H2O2 system is achieved through their reaction with the interfacial peroxide species on CeO2. The reactivity however relies on a necessary level of Ce3+ for activation. The concentration of Ce3+ from the interfacial peroxide species was ensured by the reaction of…
The continuing developments of electronic structure methods may provide insight into the vibrational spectroscopy of polysaccharides, which was not accessible to older works on this subject. The present work shows for the first time how main features of cellulose infrared spectra can be predicted and assigned using si…
Abstract Negative thermal expansion (NTE) oxides are interesting materials for use in controlled thermal expansion composites. Cubic ZrW 2 O 8 is one of the most promising candidates due to its strong, isotropic NTE behaviour over a large temperature range. It is easily accessible from a hydrated precursor, ZrW 2 O 7…
Abstract Cuprous iodide (CuI) thin films were prepared by a pulsed laser deposition (PLD) technique, and the effects of the laser energy and substrate temperature on the structure and optical–electrical properties were investigated by X‐ray diffraction (XRD), scanning electronic microscopy (SEM), transmittance spectra…
