Heritage, 2023 The removal of aged varnish on artistic paintings is a delicate intervention and the use of UV laser for this purpose is of special relevance. In particular, the use of nanosecond-pulsed lasers operating at 213 nm has been noted to produce good results ...

Practical Broad-Band Tuning of Dye Lasers by Solvent Shifting [PDF]
, 1986 We have operated a dye laser over a broad wavelength range (593.8-667.0nm) by shifting the dye emission profile with incremental changes of solvent composition. This was accomplished with the laser operating continuously, and only minor adjustment of the

Why solvent response contributions to solvation free energies are compatible with Ben-Naim's theorem [PDF]
arXiv, 2023 We resolve a seeming paradox arising from a common misinterpretation of Ben-Naim's theorem, which rests on a pairwise decomposition of the Hamiltonian of a molecular solute/solvent system into pairwise solute-solvent and solvent-solvent interactions. According to this theorem, also the solvation entropy can be decomposed into a solute-solute term and a

Compilation of Henry's law constants (version 5.0.0) for water as solvent
Atmospheric Chemistry and Physics, 2015 . Many atmospheric chemicals occur in the gas phase as well as in liquid cloud droplets and aerosol particles. Therefore, it is necessary to understand their distribution between the phases.

The green solvent: a critical perspective
Clean Technologies and Environmental Policy, 2021 Solvents are important in most industrial and domestic applications. The impact of solvent losses and emissions drives efforts to minimise them or to avoid them completely. Since the 1990s, this has become a major focus of green chemistry, giving rise to

Total Lagrangian Finite Element Formulation of the Flory-Rehner Free Energy Function
Revista Facultad de Ingeniería Universidad de Antioquia, 2014 The total Lagrangian finite element implementation of the Flory-Rehner free-energy function in the framework of a hyperelastic material model is addressed. It is explicitly given all the equations required to implement this material model in an implicit

Warburgia Salutaris Metabolites of Medicinal Value – A Review
Malaysian Journal of Science and Advanced Technology, 2023 Warburgia salutaris is a medicinal plant that occurs in central and southern Africa and has been investigated by many natural and social scientists in a somewhat fragmented and uncoordinated way.

Coupling nonpolar and polar solvation free energies in implicit solvent models [PDF]
, 2006 Recent studies on the solvation of atomistic and nanoscale solutes indicate that a strong coupling exists between the hydrophobic, dispersion, and electrostatic contributions to the solvation free energy, a facet not considered in current implicit ...
