The basic technologies used in preanalytic processes for chemistry tests have been mature for a long time, and improvements in preanalytic processes have lagged behind improvements in analytic and postanalytic processes. We describe our successful efforts to improve chemistry test turnaround time from a central laboratory by improving preanalytic processes, using existing resources and the prin...

Saeed Baghery was born in Amol/Mazandaran (Iran) in 1985. He completed his B.Sc. in Pure chemistry in 2009 from Islamic Azad University of Amol, Mazandaran, Iran. He was graduated from M.Sc. degree under the supervision of Dr. Seyed Mohammad Vahdat in Organic Chemistry from Islamic Azad University of Amol, Mazandaran, Iran. He is currently Organic Chemistry Ph.D student under the supervision of...

Amphiphilic reduced graphene oxide is obtained by oleo-functionalization with epoxidized methyl oleate (renewable feedstock) using a green process. The excellent diverse solvent-dispersivity of the oleo-reduced amphiphilic graphene and its reduction chemistry are confirmed in this study. Oleo-reduction of amphiphilic graphene is amenable to industrially viable processes to produce future graphe...

Redox chemistry is central to life on Earth. It is well known that life uses redox chemistry to capture energy from environmental chemical energy gradients. Here, we propose that a second use of redox chemistry, related to building biomass from environmental carbon, is equally important to life. We apply a method based on chemical structure to evaluate the redox range of different groups of ter...

Large scale combined Large-Eddy Simulation (LES)/Probability Density Function (PDF) parallel computations of reactive flows with detailed chemistry involving large numbers of species and reactions are computationally expensive. Among the various techniques used to reduce the computational cost of representing chemistry, the three approaches in widest use are: (1) mechanism reduction, (2) dimens...

Computational chemistry predicts that atomic motions on the femtosecond timescale are coupled to transition-state formation (barrier-crossing) in human purine nucleoside phosphorylase (PNP). The prediction is experimentally supported by slowed catalytic site chemistry in isotopically labeled PNP (13C, 15N, and 2H). However, other explanations are possible, including altered volume or bond polar...

Computational calculations of combustion problems involving real fuels with chemistry represented by detailed mechanisms are prohibitive, due to the large number of species and reactions involved. We present a new combined dimension reduction and tabulation algorithm for the efficient implementation of combustion chemistry. In this algorithm, the dimension reduction is performed using the rate ...

The use of large chemical mechanisms of hydrocarbon fuels in turbulent flame simulations is computationally expensive due to the large number of chemical species and the wide range of chemical time scales involved. The reduced description of reactive flows in combination with chemistry tabulation can effectively reduce the simulation time when detailed chemical kinetics is employed in multi-dim...
