Synthesis and Screening of t-Bu-CyMe4-BTBP,and Comparison with CyMe4-BTBP

The effect of adding a t-butyl group to the core molecule of CyMe₄-BTBP, with the aim of improving solubility in organic diluents, has been studied with regard to the extraction of Am(III) and Eu(III) from HNO₃. Synthesis of t-Bu-CyMe₄-BTBP is described in detail. Metal nitrates are extracted from nitric acid in the form of 1:2 complexes, M(NO₃)₃(BTBP)₂. Whether in 1-octanol, kerosene, or cyclohexanone diluents, t-Bu-CyMe₄-BTBP extracts with larger distribution ratios but with slower kinetics than CyMe₄-BTBP. The general trends previously observed for CyMe₄-BTBP regarding the diluent and modifier influence were also found for t-Bu-CyMe₄-BTBP.     

A Comparison Between Monolithic and Wire Gauze Structured Catalytic Reactors for CH4 and CO Removal from Biogas-Fuelled Engine Exhaust

The application of the wire gauzes as the catalytic supports can provide a number of advantages in biogas exhaust abatement. In this paper, a model of wire gauze structured reactor for biogas exhaust removal is proposed and model based calculations are performed to compare the wire gauze catalytic reactor with the classic monolith. The modelling bases on kinetic data experimentally obtained in a small-scale tubular reactor for cobalt and palladium (as reference) oxide catalysts doped with promoters (Ce, Pd). The heat and mass transfer characteristics of the wire gauze reactor are taken from the former studies by the authors. The simulations show that for assumed reactor parameters, a combination of the promoted cobalt oxide catalyst and the wire gauze support can give high conversion of methane and carbon monoxide.

Influence of the Doctor Blade Shape on Tape Casting—Comparison Between Analytical,Numerical, and Experimental Results

In this study, the influence of the shape of the doctor blade on the flow inside the tape casting unit and on the resulting tape properties is investigated both numerically and experimentally. Using the results from the analysis of the produced tape and from the simulations of the flow inside the tape casting unit, the relationships between blade geometry and the particle orientation in the resulting tape, as well as the resulting tape thickness, are shown. Additionally, the experimentally and numerically obtained results were compared to an analytical model for the prediction of the tape thickness. The simulations were carried out using the particle‐based smoothed particle hydrodynamics method using a non‐Newtonian fluid model to describe the ceramic slurry. Both in experiment and simulation, the influence of the blade geometry on the resulting tape shows good agreement.     

Tuning the Structural,Electronic, and Magnetic Properties of Strontium Titanate Through Atomic Design: A Comparison Between Oxygen Vacancies and Nitrogen Doping

The structural, electronic, and magnetic properties of seven sets of SrTiO_2.75 (oxygen vacancies) and SrTiO_2.75N_0.25 (nitrogen doping) models were investigated by the first principles calculations based on density functional theory. Our results indicated that oxygen vacancies tended to align in a chain sandwiched with Ti atoms, whereas doped nitrogen atoms (substituting oxygen atoms in SrTiO₃) preferred other arrangements rather than a chain. In addition, under stable arrangement, SrTiO_2.75 showed no magnetism, whereas magnetic moments appeared in other meta‐stable SrTiO_2.75 configurations as well as in SrTiO_2.75N_0.25, which is attributed to the Ti 3d orbitals and nitrogen p orbitals, respectively. Our results suggest a possible route for tuning magnetic and electronic properties of SrTiO₃ by atomic design.     

Comparison of the Elastic–Plastic Indentation Response of MgAl2O4, AlON,and AlN

Contact damage in the form of localized cracking and inelastic deformation is of concern in the utilization of ceramics and is often studied using hard indenters; an approach that has spawned the field of indentation mechanics. This approach was taken in the current work to study the penetration resistance at low strain rates of four candidate ceramic armor materials: MgAl₂O₄ with two grain sizes, AlON and AlN. Spherical indentation was chosen as this allows the elastic–plastic behavior to be studied and the indentation stress–strain curves to be determined. To further quantify these data, the elastic and plastic indentation work contributions were measured. On empirical grounds, it was postulated that the area under the indentation stress–strain curves, termed the indentation strain energy density, was related to the total indentation work could be used to quantify the penetration resistance. As a test of this hypothesis, it was shown that the total indentation work correlated with the strain energy density and acted over a volume similar to that of the stress field. A simple figure of merit, derived from the indentation strain energy density, was suggested as a means to quantify the penetration resistance of materials at low strain rates and to identify the material parameters that control this process.
