DMSO hydration redefined: Unraveling the hydrophobic hydration of solutes with a mixed hydrophilic–hydrophobic characteristic
PublikacjaHydrophobic hydration of solutes with a mixed hydrophilic--hydrophobic characteristics is still poorly understood. This is because both experimental and theoretical methods find it difficult to see the ice-like water structure around the nonpolar solute groups, unlike hydrogen bonds with the hydrophilic groups. In order to unravel this problem, we have investigated DMSO hydration by means of infrared spectroscopy and theoretical...

Weakly Hydrated Solute of Mixed Hydrophobic–Hydrophilic Nature
PublikacjaInfrared (IR) spectroscopy is a commonly used and invaluable tool in studies of solvation phenomena in aqueous solutions. Concurrently, density functional theory calculations and ab initio molecular dynamics simulations deliver the solvation shell picture at the molecular detail level. The mentioned techniques allowed us to gain insights into the structure and energy of the hydrogen bonding network of water molecules around methylsulfonylmethane...

Hydrophobic and hydrophilic properties of pollutants as a factor influencing their redistribution during snowpack melt
PublikacjaGlaciers accumulate organic pollutants delivered by snow. However, our understanding of the exact dynamics of organic pollutants in the snowpack relies primarily on laboratory experiments and mathematical models. To fill the gap related to the detailed field data, we have conducted observations of melting snow profiles in two locations and three different stages of melting on one High Arctic glacier, as well as in superimposed...

Comparative Evaluation of Selected Biological Methods for the Removal of Hydrophilic and Hydrophobic Odorous VOCs from Air
PublikacjaDue to increasingly stringent legal regulations as well as increasing social awareness, the removal of odorous volatile organic compounds (VOCs) from air is gaining importance. This paper presents the strategy to compare selected biological methods intended for the removal of different air pollutants, especially of odorous character. Biofiltration, biotrickling filtration and bioscrubbing technologies are evaluated in terms of...

The common effect of hydrophobic and electrophilic types of hydration dependent on protonation in the sec-butyloamine/HCl/H2O system studied by FTIR spectroscopy
PublikacjaZbadano hydratację sec-butyloaminy w zależności od pH roztworów wodnych przy pomocy spektoskopii FTIR, z zastosowaniem techniki rozcieńczenia izotopowego HDO w H2O. Dane widmowe poddano analizie przy pomocy ilościowej metody widm różnicowych. Stwierdzono, iż wiązania wodorowe cząsteczek wody tworzących klatratopodobną otoczkę hydratacyjną wokół aminy ulegają wzmocnieniu na skutek oddziaływania z grupą elektrofilową aminy.
