In order to gain a better understanding of the chemistry of methanl-to-hydro-carbon conversion, it is necessary to determine the nature of the primary reaction products. Experiments carried out in this work on H-ZSM-11, using a continuous flow reactor linked to an on-line gas chromatograph demonstrated that ethylene and methane are the primary reaction products. The results obtained using s...

The synthesis of high performance polyimide foams by the solid-state powder foaming of poly(amic acid) powders, containing hydrogen bonded blowing agent (THF), is described. During the thermal inflation of poly(amic acid) particles into polyimide microspheres, their fusion has been shown to produce the desired cellular architecture. In the present work, the solid state powder foaming process is...

The aim of the present investigation is to study the sintering behavior of the Cu12Sn bronze system in both, a microwave furnace as well as a conventional furnace. The powders prepared by premixed and prealloyed routes were sintered in the range of solid state, transient and supersolidus liquid phase sintering conditions. The comparative analysis is based on the sintered density, densification ...

The magnetic shielding tensors of protons of water in barium chlorate monohydrate are investigated at room temperature by means of solid-state NMR spectroscopy, both for static powders and under magic-angle spinning conditions, using oneand two-dimensional techniques. First-principles DFT calculations based on a periodic planewave pseudopotential formalism for a static periodic system provide s...
