Multiscale Modeling and Simulation of Organic Solar Cells [PDF]

open access: yes, 2012
In this article, we continue our mathematical study of organic solar cells (OSCs) and propose a two-scale (micro- and macro-scale) model of heterojunction OSCs with interface geometries characterized by an arbitrarily complex morphology.

Differential interaction of glimepiride and glibenclamide with the β-cell sulfonylurea receptor I. Binding characteristics [PDF]

open access: yes, 1994
Glimepiride is a novel sulfonylurea drug for treatment of non-insulin-dependent diabetes mellitus with higher blood sugar lowering efficacy in diabetic patients than glibenclamide raising the question whether this characteristics is in line with ...

NMR Line Shape Analysis of a Multi-state Ligand Binding Mechanism in Chitosanase [PDF]

open access: yes, 2017
Chitosan interaction with chitosanase was examined through analysis of spectral line shapes in the NMR HSQC titration experiments. We established that the substrate, chitosan hexamer, binds to the enzyme through the three-state induced-fit mechanism with

Shock wave study and theoretical modeling of the thermal decomposition of c-C4F8 [PDF]

open access: yes, 2015
The thermal dissociation of octafluorocyclobutane, c-C4F8, was studied in shock waves over the range 1150-2300 K by recording UV absorption signals of CF2.

The Dissociation Constants of Tetrahydrofolic Acid

open access: yesJournal of Biological Chemistry, 1966
Six dissociable groups exist in tetrahydrofolic acid in the range H0 -3.0 to pH 14. The assignments in tetrahydrofolic acid by titrimetric and spectrophotometric comparisons with model compounds, p-aminobenzoylglutamic acid and 2-amino-6,7-dimethyl-5,6,7,8-tetrahydro-4-pteridinone, are as follows: acidic ionization of amide, pK' 10.5; N5, pK' 4.82; γ ...

Strength of hydrogen bond network takes crucial roles in the dissociation process of inhibitors from the HIV-1 protease binding pocket.

open access: yesPLoS ONE, 2011
To understand the underlying mechanisms of significant differences in dissociation rate constant among different inhibitors for HIV-1 protease, we performed steered molecular dynamics (SMD) simulations to analyze the entire dissociation processes of ...

Determination of the dissociation constants of some newly synthesized derivatives of 1,2,4-triazoline-3-thione in sodium hydroxide media

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2006
The behaviour of some newly synthesized derivatives of 1,2,4-triazoline-3-thione (4-butyl-5-octyl-2,4-dihydro-3H-1,2,4-triazoline-3-thione, 4-allyl-5-octyl-2,4-dihydro-3H-1,2,4-triazoline-3-thione, 4-phenyl-5-octyl-2,4- dihydro-3H-1,2,4-triazoline-3 ...

Secondary aerosol formation from atmospheric reactions of aliphatic amines [PDF]

open access: yes, 2007
Although aliphatic amines have been detected in both urban and rural atmospheric aerosols, little is known about the chemistry leading to particle formation or the potential aerosol yields from reactions of gas-phase amines.
