Mahmoud Zarei was born in Hamedan, Iran in 1986. He received his B.Sc. in pure chemistry (2010) from Islamic Azad University Arak and M.Sc. in organic chemistry (2013) at Bu-Ali Sina University, Iran. Also, he received his Ph.D. in organic chemistry (2017) under the supervision of Prof. Mohammad Ali Zolfigol. He is currently working towards his postdoctoral under the supervision of Prof. Mohamm...

Nitro catechols via 2 hydroxyl group and a nitro group have a wide range of functions including reagents form stable complexes with more than 40 elements in the fields of analytical chemistry, biochemistry, coordination chemistry, environmental chemistry, atrium exploration, organic chemistry, pharmacy, etc. Moreover, the nitro to amine recovery has a potential function in different fields. In ...

the main aim of this research is to determine optimal leaching conditions; eh, ph and complexing agent concentrations, for recovery of copper from hydroxide sludges such as those produced by electroplating shops, metal finishers, treatment of acid mine drainage, and industrial wastewater in general. this has been preceded by a theoretical approach and numerical and computer calculation. potenti...

The objective of this work was to develop and assess an automatic procedure to generate reduced chemical schemes for the atmospheric photooxidation of volatile organic carbon (VOC) compounds. The procedure is based on (i) the development of a tool for writing the fully explicit schemes for VOC oxidation (see companion paper Aumont et al., 2005), (ii) the application of several commonly used red...

High-resolution FT-IR spectroscopy combined with quantum chemical calculations was used to study the chemistry of OCS-disproportionation over the reduced surface of isotopically labelled, nanocrystalline TiO2. Analysis of the isotopic composition of the product gases has revealed that the reaction involves solely OCS molecules from the gas-phase. Using quantum chemical calculations we propose a...

An adaptive approach for coupling detailed kinetics with computational fluid dynamics (CFD) has been formulated to permit reactive flow simulations with improved computational efficiency. The approach makes use of a set of reduced mechanisms, each of which has been developed to reproduce the mixture kinetics under well-characterized thermo-chemical conditions. In the present implementation, the...

We investigate utilizing the integer programming (IP) technique of reduced cost fixing to improve maximum satisfiability (MaxSAT) solving. In particular, we show how reduced cost fixing can be used within the implicit hitting set approach (IHS) for solving MaxSAT. Solvers based on IHS have proved to be quite effective for MaxSAT, especially on problems with a variety of clause weights. The uniq...

A case-based reasoning system was created to support customers who purchased appliances from General Electric. When a customer calls General Electric for help, a call-taker uses the system to diagnose the problem and step the customer through its solution. The system has been in use by 300 call-takers since 1999. It has resulted in a 20 percent increase in the probability the customer’s problem...

The effect of a salient visual feature in orienting spatial attention was examined as a function of the learned association between the visual feature and the observer’s action. During an initial acquisition phase, participants learned that two keypress actions consistently produced red and green visual cues. Next, in a test phase, participants’ actions continued to result in singletons, but th...
