As there are some health and environmental concerns about wastewater, dewatered sludge, increase in green waste, and restricted legislation about burning them outdoors, environmental health engineers are investigating to find a simple, cost effective and efficient method. This is aimed to have healthy, safe and sustainable disposal of such materials. Co-composting of sludge and green waste is a...
Corn dried distiller’s grain with solubles (cDDGS) is a feeding ingredient for monogastric animals but limited inclusion rate due to its imbalanced amino acids, high fiber content, and anti-nutritional compounds. Moreover, production of cDDGS costly energy intensive. This study investigated fungal fermentation corn stillage mixing other dry agro-industrial residues which could by-pass the energ...
The angular and velocity distributions of desorbing product N(2) were examined over the crystal azimuth in steady-state NO+CO and N(2)O+CO reactions on Pd(110) by cross-correlation time-of-flight techniques. At surface temperatures below 600 K, N(2) desorption in both reactions splits into two directional lobes collimated along 41 degrees -45 degrees from the surface normal toward the [001] and...
We report here the direct formation of the new chemical product trans-2,5-dihydroxy-3-pentenoic acid methyl ester from pentoses using tin-containing silicates as catalysts. The product is formed under alkali-free conditions in methanol at temperatures in the range 140–180 C. The highest yields are found using Sn-Beta as the catalyst. Under optimised conditions, a yield of 33% is achieved. Purif...
The 266 nm light-induced reaction of CO2 and H2O gas mixtures (including isotopic modifications CO2, CO2, and D2O) in framework TiMCM-41 silicate sieve was monitored by in-situ FT-IR spectroscopy at room temperature. Carbon monoxide gas was observed as the sole product by infrared, and the growth was found to depend linearly on the photolysis laser power. H2O was confirmed as stoichiometric ele...
Incorporation of (18)O into the CO(2) produced in the bioluminescent oxidation of firefly luciferin was studied. In H(2) (16)O medium with (18)O(2) gas, the product CO(2) contained up to 75% C(16)O(18)O, showing that one O of the product CO(2) arose from the O(2) that oxidized luciferin. This result is consistent with a dioxetane mechanism. Analysis of the mass spectral data of the CO(2) obtain...
The oxidative carbonylation of methane to acetic acid was investigated using Pt(II) cations as the catalyst and sulfuric acid as the solvent. The eactions were carried out at 180 ◦C in a sealed batch reactor containing either fuming or concentrated (96 wt%) sulfuric acid (3 ml) and PtCl2 20 mM) in the liquid-phase, and pressurized with CH (400 psi) and CO (400 psi). In the absence of CO, the on...

[((Ar) PMI)Mo(CO)4 ] complexes (PMI=pyridine monoimine; Ar=Ph, 2,6-di-iso-propylphenyl) were synthesized and their electrochemical properties were probed with cyclic voltammetry and infrared spectroelectrochemistry (IR-SEC). The complexes undergo a reduction at more positive potentials than the related [(bipyridine)Mo(CO)4 ] complex, which is ligand based according to IR-SEC and DFT data. To pr...
Forecasting customers’ responses and market competitions is essential before launching major technological changes in product design. In this research, we present a data-driven network analysis approach to understand the interactions among technologies, products, and customers. Such an approach provides a quantitative assessment of the impact of technological changes on customers’ co-considerat...
