Abstract A thermoplastic polymer solution was inkjet printed in a pre‐defined hexagonal pattern onto carbon fibre reinforced epoxy resin (CFRP), leading to a significant increase in strength, stiffness and toughness of the final aerospace grade compo‐site system. The approach consisted of depositing low‐viscosity poly…
In this paper, a dynamic light scattering (DLS)-based approach was developed for the real-time detection of melamine. Due to the strong interaction between melamine and AuNPs, the hydrodynamic diameter of AuNPs changed with increasing amounts of added melamine in the detection system, which can be directly observed by…
Embedded actuator and sensor technology provides accurate structural health monitoring and proper structural response of a structure in any harsh servicing situation. This paper describes the fabrication of a smart composite by embedding shape memory alloy (SMA) wires and fibre Bragg grating (FBG) sensors into a glass…
Using a simple synthetic protocol, heterohexacene analogues with a quadrupolar distribution of partial charges are readily available. In contrast to most other acenes, these compounds crystallize with a slipped-stack, brickwork-like packing which is mainly controlled by electrostatic interactions. This type of packing…
OBJECTIVE: To determine and analyse the characteristics of contrast media adverse reactions (CM-ARs) reported in a hospital. METHODS: A retrospective review of CM-ARs from the electronic spontaneous adverse drug reaction (ADR) report system between January 2011 and August 2012 was conducted. CM-ARs were evaluated in t…
The reactions among Eu2O3, AlN, and Al2O3 with the ratios Eu:Al = 2:1 and 1:2 at 1200 °C for 10 h yielded Eu2AlO(3.75)N(0.1) and EuAl2O4, respectively. The powder X-ray diffraction pattern of the new oxynitride could be indexed as a monoclinic structure with the space group I2 (No. 5) (a = 3.7113(2) Å, b = 3.6894(2) Å…
The spatial distribution of reactants and products of infiltrationdriven decarbonation reactions can be a record of the geometry and amount of reactive fluid flow during regional metamorphism. In the past, these distributions have been interpreted assuming (1) minerals are fixed in composition and (2) single layers ar…
NiFe2O4 nanoparticles with an average grain size of 31 nm were synthesised by a polyacrylamide gel route. Their bandgap energy obtained by ultraviolet–visible diffuse reflectance spectroscopy is 1·85 eV. NiFe2O4–graphene nanocomposites were fabricated by mixing NiFe2O4 nanoparticles and graphene into absolute ethanol…
Fullerenols C60(OH) have therapeutic potential, but there is debate regarding their toxicity. Here, we tested the hypothesis that C60(OH)n possesses a pro-inflammatory effect in vivo. Kinetic and dose-dependent experiments performed with the murine air pouch model of acute inflammation revealed that, unlike TiO2 used…
We present a simple yet effective theory that predicts the existence of resonant radiation bands in the deep normal group-velocity dispersion region of a medium, even in the absence of a zero-group-velocity dispersion point. This radiation is evident when the medium is pumped with high-energy ultrashort pulses, and it…
Al/MoOx nanoenergetic multilayer films (nEMFs) were deposited by magnetron deposition method. The samples with bilayer thicknesses of 75 nm and 225 nm were prepared, respectively, and the total thickness is 3 μm. The as-deposited Al/MoOx nEMFs were characterized with varied analytical techniques, including SEM, XRD, X…
Effective treatment of diseases at the molecular level is possible by directing the drug substance (micromolecular, protein or peptide drugs, DNA, oligonucleotides, siRNA) with the aid of a specialized nanoparticulate carrier, for safe and effective transport to the specific site of action in the cytosol and its organ…
Solidification of lamellar cast iron is a complex mechanism due to the contracting austenite phase and the expanding graphite phase precipitation. The combined effect of contraction–expansion has an influence on the volume change related defects (shrinkage porosity and penetration). Critical moments in measuring volum…
We report on a simple strategy for the direct synthesis of a thin film comprising interconnected NiO nanoparticles deposited on both sides of a graphene sheet via cathodic deposition. For the co-electrodeposition, graphene oxide (GO) is treated with water-soluble cationic poly(ethyleneimine) (PEI) which acts as a stab…
The Danish sculptor Anne Marie Carl-Nielsen (1863–1945) often prepared three-dimensional models in wax before producing her works of art. The Carl Nielsen Museum in Odense keeps a unique collection of around 200 of the artist's fragile wax models. In 2008 the entire collection was examined, documented, X-ray radiograp…
Redox behavior of endohedral metallofullerenes, in particular their oxidation process, can be classified as a fullerene-based or endohedral species-based process according to the mechanism of the electron transfer. Here we report on the phenomenon of the strain-driven electrochemical behavior achieved by encapsulating…
Surface modification of beech wood layers was first carried out by rinsing them in distilled water, followed by surface activation with nickel metallic as a catalyst that is prepared on beech wood surface by reduction of Ni+2 ions using as a reduction agent at pH 11. Finally, the nickel was deposited by electroless ni…
Highly transparent Cr, Tm, Ho triple-doped Y3Al5O12 (YAG) ceramics were prepared using advanced ceramic technology and their spectroscopic properties were studied for infrared laser applications. 2.09 μm emission was observed by exciting at 430 nm, which indicated the realization of energy transition from Cr3+ to Ho3+…
The UV photolysis of dimethylcarbamoyl azide has been investigated in an argon matrix at cryogenic temperatures. The products of the photolysis were identified by infrared spectroscopy supported by quantum-chemical calculations. Sequential formation of dimethylamino isocyanate (Me2N-NCO), 1,1-dimethyldiazene (Me2N═N),…
Brushite forming calcium phosphate cements receive growing interest in hard tissue scaffold applications due to their high surface area and high bioresorbability. The finer microstructure of monetite, the dehydrated form of brushite, has attracted attention for bone tissue engineering applications. The reduction in br…
