Solvent effect on electronic absorption spectra of cyclohex-1-enylcarboxylic and 2-methylcyclohex-1-enylcarboxylic acids [PDF]
The ultraviolet absorption spectra of cyclohex-1-enylcarboxylic acid and 2-methylcyclohex-1-enylcarboxylic acid were determined in six protic and nine aprotic solvents in the wavelength range from 200 to 400 nm.

Theoretical Investigation of Solvation Effects on the Tautomerism of Maleic Hydrazide
A DFT study is used to calculate structural data of tautomers of maleic hydrazide (MH) in the gas phase and selected solvents such as benzene (non-polar solvent), tetrahydrofuran (polar aprotic solvent) and methanol (protic solvent), dimethyl sulfoxide ...

Dispersions of Goethite Nanorods in Aprotic Polar Solvents [PDF]
Colloidal suspensions of anisotropic nanoparticles can spontaneously self-organize in liquid-crystalline phases beyond some concentration threshold. These phases often respond to electric and magnetic fields. At lower concentrations, usual isotropic liquids are observed but they can display very strong Kerr and Cotton-Mouton effects (i.e., field ...

The Role of Solvent on the Kinetics and Mechanism of the Hydrolysis of Salicylidene Benzoyl Hydrazone [PDF]
The effect of various solvents on the kinetics and mechanism of the hydrolysis of Salicylidene Benzoyl hydrazone (SBH) has been studied at five different temperatures (17-45 C) using U.V. and visible spectrophotometry. In both protic and aprotic solvents,

Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.
