The dynamics of carburization of Mo-oxo precursors exchanged onto H-ZSM-5 strongly influence initial induction periods and steady-state rates during catalytic pyrolysis of CH4 to alkenes and arenes at 900-1000 K. The effects of co-reactants and of activating conditions were examined by on-line time-resolved mass spectrometric analysis of effluent streams using rigorous analyses to account for e...

We report on the synthesis of multifunctional Ag-TiO2 nanocomposites and their optical, physio-chemical, surface enhanced Raman scattering (SERS) and antibacterial properties. A series of Ag-TiO2 nanocomposites were synthesized by sol-gel technique and characterized by x-ray diffraction, scanning and transmission electron microscopy, energy-dispersed x-ray analysis, photoluminescence, UV-vis, x...

Sexual reproduction and genetic variation of the scleractinian coral Mycedium elephantotus at Maoao (MO), Yenliao Bay, northern Taiwan, and at Tiaoshi (TS), Nanwan Bay, southern Taiwan, were studied from 1990 to 1996. M. elephantotus is a hermaphroditic broadcast spawner with an annual reproductive cycle. Gametogenesis of the MO population began in January, and spawning occurred in July-August....

A bout the time Fred Brooks was warning us there was not likely to be a single, “silver bullet” solution to the essential difficulties of developing software [3], Watts Humphrey and others at the Software Engineering Institute (SEI) were busy putting together the set of ideas that was to become the Capability Maturity Model (CMM) for Software. The CMM adopted the opposite of the quick-fix silve...

Passivation of the Cu(In,Ga)Se2 (CIGS)/Mo back contact using AlO x is studied to reduce recombination at this interface. Herein, RbF postdeposition treatment (RbF-PDT), a well-established method improve absorber and front interface properties used on back-passivated solar cells. It found that combination deteriorates performance due formation an injection barrier reduced acceptor concentration....

We address the problem of multi-objective constraint optimization problems (MO-COPs). Solving an MO-COP traditionally consists in computing the set of all Pareto solutions (i.e. the Pareto front). But this Pareto front is exponentially large in the general case. So this causes two main problems. First is the time complexity concerns. Second is a lack of decisiveness. In this paper, we present t...

Abstract In this work, a series of hypercrosslinked polymers intrinsic microporosity (HCP-PIMs), namely nitro-triptycene (TRIP-NO 2 ), amino-triptycene (TRIP-NH sulfonated-triptycene (TRIP-SO 3 H) and hydrocarbon-triptycene (TRIP-HC), are employed for the adsorption organic dyes from wastewater. The materials show efficient removal cationic (malachite green, MG) anionic (methyl orange, MO) dyes...
