In the current work, a framework is presented for amine solvent selection in gas treating process. Since the appropriate decision making in this field affects the capital and operational costs, multi attribute decision making (MADM) techniques were used to rank alternatives. The determination of criteria and alternatives is the most important aspect in the MADM. Criteria were divided into two c...

We investigated interactions of bispyridinium para-aldoximes N,N'-(propano)bis(4-hydroxyiminomethyl) pyridinium bromide (TMB-4), N,N'-(ethano)bis(4-hydroxyiminomethyl)pyridinium methanosulphonate (DMB-4), and N,N'-(methano)bis(4-hydroxyiminomethyl)pyridinium chloride (MMB-4) with human erythrocyte acetylcholinesterase phosphorylated by tabun. We analysed aldoxime conformations to determine the ...

The title complex, [Cu(C(4)H(10)N(4)O)(2)](ClO(4))(2) or [Cu(L(1e))(2)](ClO(4))(2), where L(1e) is 1-carbamimidoyl-2-ethyl-isourea, was obtained from the ethano-lysis reaction of 2-cyano-guanidine and copper(II) perchlorate hexa-hydrate in a 2:1 molar ratio. The two bidentate L(1e) ligands are coordinated to the Cu(II) center through N-donor atoms, leading to the CuN(4) chromophore. The Cu(II) ...

It is well known that small amount Piperazine (PZ) enhance the CO2 absorption properties of tertiary amine aqueous solution. Because the tert-amine has the lower heat of reaction, the blended amine solution, tert-amine with PZ, is attractive for low energy absorbent. There are some reports about the investigation of the mechanism of the blended amine solution, however, there still a difficulty ...

in this paper, we report on the synthesis of cu nanoparticles through a single-precursor route by controlling the growth temperature. selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. the understanding of this self-assembling process will help us develop reliable and reproducible methods to synthesis other three dimensional nanostruct...

Amine-modified mesoporous SBA-15 adsorbent has been prepared by impregnation method using tetraethylenepentamine. The samples of this modified SBA-15 have been characterized by small angle X-ray scattering (SAXS), Scanning electron microscopy (SEM), Nitrogen adsorption-desorption isotherm and FT-IR. The adsorption capacity of CO2 on unmodified and modified samples were measured at high pressure...

Presynaptic biogenic amine transporters mediate reuptake of released amines from the synapse, thus regulating serotonin, dopamine and norepinephrine neurotransmission. Medications utilized in the treatment of depression, attention deficit-hyperactivity disorder and other psychiatric disorders possess high affinity for amine transporters. In addition, amine transporters are targets for psychosti...
