N-Doped meso-macroporous carbon materials were synthesized using melamine-formaldehyde resin as carbon precursor and silica spheres as a removable template. The as-synthesized carbon materials with a bimodal pores structure (about 3.9 and ∼50–200 nm) display a high surface nitrogen content of 30 wt %. The macropores o…
The half-metallicity and electronic structures for the bulk, surfaces and interfaces of zinc blende (ZB) NiO are investigated by using full potential linearized augment plane wave method with the modified Becke and Johnson potential. Obtained results reveal ZB NiO is half-metallic ferromagnet with half-metallic gap 0.…
Abstract The sulfonated bipyridine derivative disodium 6,6′‐bis(sulfonatomethyl)‐2,2′‐bipyridine [Na2(smbipy)] was synthesized, and its complexation behaviour towards divalent 3d metals in aqueous solution was explored. The complexes of late 3d metals [M(smbipy)(H2O)2]·H2O (M = Co, Ni, Zn) and [Cu(smbipy)(H2O)] are sp…
The solubilities and refractive indexes in the NH4Cl-CaCl2-H2O system were measured at 50 and 75°C and the phase diagrams were constructed on the basis of the experimental data. The mixing parameters and equilibrium constant K sp were evaluated using the Pitzer ion-interaction model representations. The results obtain…
Soft phonon modes, which are related to the normal–incommensurate phase transition at Ti = 294 K and the lowest-temperature phase transition at T3 = 66 K in Rb2CoCl4, have been measured by inelastic neutron scattering. For the normal–incommensurate phase transition, phonon dispersion curves have been determined in the…
This paper examines carbon dioxide (CO 2 ) separation from natural gas, mainly methane, through a 15 nm alumina tubular ceramic membrane before and after silica modification. A laboratory scale of tubular silica membrane with a permeable length of 348 mm, I.D and O.D of 7 and 10 mm respectively was used in this experi…
The central motto 'Radiation Protection Culture-A Global Challenge' of the fourth European IRPA Congress is discussed on the basis of the IRPA Guiding Principles Establishing a Radiation Protection Culture and the contributions presented in the plenary sessions of the conference.
Two copper(II) complexes, 1 and 2, of two ligands, L1 and L2 [L1 = 2-{[anthracen-9-ylmethyl-(2-dimethylamino-ethyl)-amino]-methyl}-4,6-di-tert-butyl-phenol; L2 = 5-dimethylamino-naphthalene-1-sulfonic acid (3,5-di-tert-butyl-2-hydroxy-benzyl)-(2-dimethylamino-ethyl)-amide, were synthesized and characterized. In methan…
We have simulated IR and pyrolysis gas chromatography mass spectrometry (Py-GCMS) spectra of six polymers (PE, PP, PS, PET, N6, PVDF) with the density-functional theory and quantum molecular dynamics calculations on model oligomers. In the former calculations, experimental harmonic frequencies of the polymers have bee…
The reliability and efficiency of power equipment is largely depend on the degree of wear in its most loaded elements, which during operation undergo the cumulative effects of various factors. The mutual manifestation of several kinds of wear leads to the intensification of the destruction processes that will reduce e…
In this work, we report on the magnetic and dielectric anomalies observed in dense Bi 1– x RE x FeO 3 ceramics ( RE = Dy , Tb ; 0 ≤ x ≤ 0.3) at cryogenic temperatures. For compositions with a high content of rare‐earth ions, thermomagnetic experiments revealed a distinct anomaly in the magnetization curves at temperat…
We study the exciton contribution to the third-order optical susceptibility of one-dimensional semiconductor quantum dots and show that the screening of the electron-hole interaction has a strong influence on the nonlinear optical properties in the weak confinement regime. Based on a density matrix formulation, we est…
We demonstrate the influence of phenyl groups in the pore structure of mesoporous organosilicas, on the quantity of absorbed enzyme and the activity of immobilized enzyme.
Based on the principle of transformation optics, we propose to control the wave propagating direction through the homogenous anisotropic medium designed by linear coordinate transformation. The material parameters of the medium are derived from the linear coordinate transformation applied. Keeping the space area uncha…
Although not being classified as the most fundamental protein structural elements like α-helices and β-strands, the loop segment may play considerable roles for protein stability, flexibility, and dynamic activity. Meanwhile, the protein loop is also quite elusive; i.e. its interactions with the other parts of protein…
We report on the energy transport between two coupled probes in contact with granular thermostats at different temperatures. In our experiment, two identical blades, which are electromechanically coupled, are immersed in two granular gases maintained in different non-equilibrium stationary states, characterized by dif…

Deformable polymer photoswitches with p-doped single layer graphene as the top window electrode exhibit an on/off ratio as high as 8.5 × 10 5 .
Synthetically-manufactured ammonia fuel is proposed for distribution throughout Australia when we need to replace future diminishing petroleum resources. In the interim this would be derived from natural gas resources using the Haber Bosch process, leading to a progressive transition to 100% energy resourcing from sus…
