The propylene production with 1-butanol co-feeding for methanol in relation to propylene process (MTP) at 440-490 ̊C temperature range and at 0.9-15 hr-1 WHSV range over H-ZSM-5 zeolite catalyst is assessed in a isothermal fixed-bed reactor. The feedings here are of: pure 1-butanol, pure methanol and a 1-butanol and methanol mixture. The effect of 1-butanol co-feeding on selectivity of propylene...

   To fabricate a defect free and high performance mixed matrix membrane (MMM), one approach is the functionalization of inorganic nanofillers (as dispersed phase) in the organic polymer matrix (as continuous phase) to modify the interactions between two phases.  For this purpose,, raw multi-walled carbon nanotubes (rMWCNTs) were purified by acid mixture (HNO3/H2SO<sub...

Co-amorphous drug amino acid mixtures were previously shown to be a promising approach to create physically stable amorphous systems with the improved dissolution properties of poorly water-soluble drugs. The aim of this work was to expand the co-amorphous drug amino acid mixture approach by combining the model drug, naproxen (NAP), with an amino acid to physically stabilize the co-amorphous sy...

Significantly increased aCtlVlfY of Cr(CO)6 was achieved for the stereoselective homogeneous hydrogenation of methyl sorbate and tmns,trans-conjugated fatty esters at ambient temperature and pressure by exposing the catalyst to UV irradiation (3500.'1.) in a solvent mixture of cyclohexane-acetonitrile (20:1). In this solvent mixture, methyl sorb ate was converted quantitatively at ambient condi...

We study a mixture of spin-1 bosonic and spin-1/2 fermionic cold atoms, e.g., ^{87}Rb and ^{6}Li, confined in a triangular optical lattice. With fermions at 3/4 filling, Fermi surface nesting leads to spontaneous formation of various spin textures of bosons in the ground state, such as collinear, coplanar, and even noncoplanar spin orders. The phase diagram is mapped out with varying boson tunn...

The measured rates for CO, dissociation on Rh(ll1) are reported for a Ha/CO, reaction mixture at a total pressure of 100 Torr and a CO, partial pressure of 1 Torr. The activation energy associated with the conversion of CO, to CO is 17 kcal/mol. The reaction probabilities for CO, dissociation range from 10-s at 750 K to 10-s at 444 K. The probability of CO, dissociation on Rh(ll1) is shown to b...

1. Investigations were made into the breast and leg muscle energy metabolism, and the quality of breast meat of turkeys after controlled atmosphere stunning or stun-killing (CAS) with various gas mixtures. In addition, the effect on meat quality of an increase in the chilling rate of turkey breast meat after hypercapnic or anoxic stun-killing was studied. 2. A total of 35 turkey toms within t...
