Reichardt’s Dye-Based Solvent Polarity and Abraham Solvent Parameters: Examining Correlations and Predictive Modeling

open access: yesLiquids, 2023
The concept of “solvent polarity” is widely used to explain the effects of using different solvents in various scientific applications. However, a consensus regarding its definition and quantitative measure is still lacking, hindering progress in solvent-

Improved Generalized Born Solvent Model Parameters for Protein Simulations [PDF]

open access: greenJournal of Chemical Theory and Computation, 2013
The generalized Born (GB) model is one of the fastest implicit solvent models and it has become widely adopted for Molecular Dynamics (MD) simulations. This speed comes with tradeoffs, and many reports in the literature have pointed out weaknesses with GB models.

AbraLlama: Predicting Abraham Model Solute Descriptors and Modified Solvent Parameters Using Llama [PDF]

open access: diamondLiquids
This study explores the application of fine-tuned large language models for predicting physicochemical properties, specifically focusing on Abraham model solute descriptors (E, S, A, B, V) and modified solvent parameters (e0, s0, a0, b0, v0).

The kinetics of the reactions of 2-substituted nicotinic acids with diazodiphenylmethane in various alcohols [PDF]

open access: yesJournal of the Serbian Chemical Society, 2003
The rate constants of 2-substituted nicotinic acids in reaction with diazodiphenylmethane (DDM) in eight alcohols at 30ºC have been determined. In order to explain the obtained results through solvent effects, the second order reaction rate constants (k)

SOLVATOCROMISMO E AS ESCALAS EMPÍRICAS DE POLARIDADE DO SOLVENTE: UMA REVISÃO [PDF]

open access: yesQuímica Nova, 2023
The term solvatochromism is used to describe the changes in the optical properties of a dye molecule by influence of the solvent characteristics. Solvatochromic shifts are governed by intermolecular interactions between solute-solvent that can be either ...
