TLDR
In this paper, a new parametric quantum mechanical molecular model, AM1 (Austin Model l), based on the NDDO approximation, is described, in which the major weaknesses of MNDO, in particular failure to reproduce hydrogen bonds, have been overcome without any increase in computing time.
Abstract
A new parametric quantum mechanical molecular model, AM1 (Austin Model l), based on the NDDO approximation, is described. In it the major weaknesses of MNDO, in particular failure to reproduce hydrogen bonds, have been overcome without any increase in computing time. Results for 167 molecules are reported. Parameters are currently available for C, H, 0, and N.

Variational transition-state theory and semiclassical tunnelling calculations with interpolated corrections: a new approach to interfacing electronic structure theory and dynamics for organic reactions

TL;DR: In this article, a three-point or zero-order interpolated correction method is proposed to match the classical energies and vibration frequencies of some points (e.g. the reactant, saddle point, product, van der Waals complex, ion-molecule complex) along the minimum energy path (MEP) and in the reaction swath with high-level results.

Effect of structural properties of acid dyes on their adsorption behaviour from aqueous solutions by amine modified silica.

TL;DR: The adsorption behaviour of the two dyes was studied at different experimental conditions of pH, contact time, concentration of dye, temperature and salt solution and showed different modes of interaction with silica surface.

Pyrano[3,2-c]quinoline−6-Chlorotacrine Hybrids as a Novel Family of Acetylcholinesterase- and β-Amyloid-Directed Anti-Alzheimer Compounds

TL;DR: Two isomeric series of dual binding site acetylcholinesterase (AChE) inhibitors that retain the potent and selective human AChE inhibitory activity of the parent 6-chlorotacrine while exhibiting a significant in vitro inhibitoryActivity toward the AChe-induced and self-induced Abeta aggregation and toward BACE-1, as well as ability to enter the central nervous system, which makes them promising anti-Alzheimer lead compounds.

Inhibitive properties, adsorption and a theoretical study of 3,5-bis(n-pyridyl)-4-amino-1,2,4-triazoles as corrosion inhibitors for mild steel in perchloric acid

TL;DR: In this article, mild steel in molar perchloric acid by 3,5-bis(n-pyridyl)-4-amino-1,2,4-triazoles (n-PAT, n = 2, 4, 3 and 4) was studied at 30°C using gravimetric and electrochemical impedance spectroscopy techniques.
