We have investigated the thermodynamics of sulfuric acid dimer hydration using ab initio quantum mechanical methods. For (H(2)SO(4))(2)(H(2)O)(n) where n = 0-6, we employed high-level ab initio calculations to locate the most stable minima for each cluster size. The results presented herein yield a detailed understanding of the first deprotonation of sulfuric acid as a function of temperature f...

We developed a TiO 2 -supported single-atom Mo catalyst (Mo 1 /TiO ) where single atoms paired with the neighboring surface Ti function as Mo–Ti acid–base dual sites, realizing decomposition of ABS at ?225 °C.

Ionic diffusion coefficients in the membrane are needed for modelling of ion transport ion-exchange membranes (IEMs) with Nernst-Planck equation. We have determined ionic Na+, OH?, H+, Cl?, SO42?, NaSO4?, and HSO4? from experiments dilute NaCl, NaOH, HCl, Na2SO4, H2SO4 solutions through IEMs conductivity measured these solutions, using electrochemical impedance spectroscopy. The order fluxes ac...

T-cadherin functions as a suppressor gene, which is frequently inactivated by aberrant promoter methylation in several human cancers, but its status oral squamous cell carcinoma (OSCC) has been scarcely studied. Thus this study aimed at exploring the clinical significance and prognostic value of sera patients with OSCC. Methylation-specific PCR (MSP) bisulfate sequencing (BSP) was performed to ...

Graphene-polypyrrole (GP) nanocomposites were synthesized by a wet-way protocol using graphite bisulfate (GBS) precursor. Consequently, GBS, type of intercalation compound, was prepared in the presence concentrated sulfuric acid potassium periodate oxidizer. Three different types precursor with particle sizes <50 μm, ≥150, ≤830 and ≤2000 μm used for this purpose. It found that Raman spectra ...

objective studies on the effect of various antiepileptic drugs on serum lipids show contradictory results. we aimed to find the effect of phenobarbital and sodium valproate monotherapy on serum lipid profile and liver function tests in epileptic children. materials & methods this cohort study was conducted in amirkola children hospital. one hundred and ten children with epilepsy were included i...

• The water molecules and the bisulfate dianions are, respectively, those which diffuse more less at all temperatures acid concentrations. hydrogen bond network partially breaks when concentration or temperature increases. bonded to anions are most labile concentrations temperatures. interrupted lifetimes increase activation energies of rises. Molecular dynamics simulations sulfuric solutions s...
