A new class of alkyland perfluoroalkyl-containing urea and amide derivatives was synthesized from amino acid derivatives. Most of these compounds showed excellent gelation behavior in organic solvents at low concentrations. A few organogelators selected from the initial screening were used for surface modification of fibrous substrates to create hydrophobic and oleophobic composites. The hydrop...
Nitros(yl)ation is a widespread protein modification that occurs during many physiological and pathological processes. It can alter both the activity and function of a protein. Nitric oxide (( small middle dot)NO) has been implicated in this process, but its mechanism remained uncertain. ( small middle dot)NO is unable to react with nucleophiles under oxygen-free conditions, suggesting that its...
background and aims. adhesive permeability is hindered by application of an additional layer of hydrophobic resin, which increases its concentration within the hydrophilic layer, reduces its affinity to water, and enhances its physical properties. the aim of the present study was to evaluate the effect of a hydrophobic layer on the microleakage of class v composite restorations using different ...
Entrapment within surface-crosslinked micelles (SCMs) enhanced the emission of conventional hydrophobic fluorescent dyes, endowed them with excellent water solubility and membrane permeability, and greatly expanded the Stokes shifts without any covalent structural modification of the dyes.
