BACKGROUND: Rheological analysis can be employed as a sensitive tool in predicting the physical properties of gold nanoparticles (GNPs). Understanding the rheological properties of GNPs can help to develop a better therapeutic cancer product, since these physical properties often link material formulation and processi…
We report a simple method of covalent functionalization of graphene with an organic donor such as oligo(phenylenevinylene) (OPV). We present morphological proof for the unprecedented self-organization of these hybrids into higher order assemblies, with a periodic spacing of ∼2.3 nm, intercalated with OPV molecules. Af…
The consolidation of Sm2Fe17N3 powder was examined by pulsed current sintering below its decomposition temperature. Although decomposition of the powder was not observed, its coercivity decreased dramatically. Annealed powder was observed by transmission electron microscopy in order to clarify the mechanism for the re…
The esterification of salicylic acid with methanol was carried out over a series of Ce 4+ modified cation-exchange resins. The effect of different reaction conditions was studied on the conversion of salicylic acid, and the optimal reaction parameters were obtained. The experimental results indicated that Ce(SO 4 ) 2…
The dynamic shear deformation behaviour and fracture characteristics of 316L stainless steel are investigated using a split-Hopkinson torsional bar system at temperatures of −150, 25 and 300°C and strain rates ranging from 1000 to 3000 s−1. The results show that the flow stress, shear fracture strain, work hardening r…
The electrochemical behavior of aluminium alloy AA6063 were investigated using Schiff base compounds namely N, N'-bis (Salicylidene)-1, 2-Diaminoethane(Salen) and N, N'-bis (3-Methoxy Salicylidene)-1, 2 Diaminoethane (Msalen) as corrosion inhibitors in presence of 1M Hydrochloric Acid by Potentiodynamic polarization(P…
Introduction Cardiovascular disease (CVD) is a leading cause of mortality in most developed countries accounting for 30% of all deaths worldwide in 2008 [1]. Current trends in obesity and the lack of a healthy lifestyle will likely lead to an increase in total population suffering from heart diseases, causing associat…
We describe the phase behavior of a ternary blend of poly(ethylene-alt-propylene) (P), poly(cyclohexylethylene-b-ethylene-b-cyclohexylethylene) (CEC), and a CECEC–P amphiphilic hexablock where both CEC and CECEC–P are ordered in the bulk. In this system, designed to mimic A/B/A–B ternary polymer blends, CEC and P were…
Charge order affects most of the electronic properties but is believed not to alter the spin arrangement since the magnetic susceptibility remains unchanged. We present electron-spin-resonance experiments on quasi-one-dimensional<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:msub><mml:mrow><mml:…
By exploring the phenomenon of water diffusion induced self-assembly of silica particle in microfluidic channels, we show that both the geometric confinement experienced by the droplet and the local Peclet number are responsible for the final particle shape. This study will facilitate the understanding and ultimately…
Surface modification of low modulus implant alloys with oxide nanostructures is one of the important ways to achieve favorable biological behaviors. In the present work, amorphous Ti‐Nb‐Zr‐O nanostructures were grown on a peak‐aged Ti35Nb5Zr alloy through anodization. Biological properties of the Ti‐Nb‐Zr‐O nanostruct…
3-Methylcyclohexanone is only partially resolved by crystallisation with a chiral diol host compound (ee 40%), but when recrystallised from an equimolar mixture of the chiral diol host and a similar but achiral host we obtain complete resolution. The latter host acts as a nucleation inhibitor and the enhanced resoluti…
The shear moduli of two-component glasses in two dimensions are studied within mode coupling theory. Varying the concentration, strong mixing effects are observed along the glass transition lines for two interaction potentials. Nonoverlapping disks with size ratios between 0.3 and 0.9, and point particles interacting…
Hierarchically ordered structures are fabricated by laser irradiation on azobenzene-containing polymers through PDMS phase masks. The longer and shorter length scale structures of the hierarchical structures are interference patterns and self-organized nanostructures, respectively. The hierarchical structures are tuna…
Abstract We present a novel method for integrating single CuO nanowires as gas sensing components in a suspended configuration. In these devices, the nanowire surface area that is actually exposed to the surrounding gas atmosphere is increased, which is favourable when operating the nanowire as conductometric gas sens…
Halogen free fire-retardant silicon rubber compounds for cable covering materials were prepared, using Magnesium hydroxide (MH), microencapsulated red phosphorous (MRP) as a synergist agent. Tensile Test was used to testify the mechanical properties. Limiting oxygen index (LOI) and UL 94 test were used to characterize…
Novel analytical models for surface field distribution and saturation region length for double gate graphene nanoribbon transistors are proposed. The solutions for surface potential and electric field are derived based on Poisson equation. Using the proposed models, the effects of several parameters such as drain-sour…
We have investigated the bias electric field dependence of the photocurrent for LaMnO3/Nb-doped SrTiO3 heterostructures. The photocarriers generated in LaMnO3 are more efficiently injected into Nb-doped SrTiO3 when the reverse bias voltage is applied. Within the rigid-band scheme, this can be attributed to the bias vo…
Small aromatic dipeptides can self-assemble into supramolecular bioinspired peptide nanotubes. Nanoscale dimensions of their nanocrystalline building blocks and their space symmetry is the origin for exceptional physical properties of these nanotubular structures, such as quantum confinement and ferroelectric-related…
After in situ baking, Non-evaporable getter (NEG) alloys are able to pump most of the gases present in ultra-high vacuum systems. Titanium-Zirconium-Vanadium (TiZrV) NEG films, which exhibits the lowest activation temperature, have been deposited on the inner wall of a stainless steel pipe via DC magnetron sputtering.…
