Hydrophobic pattern of alkylated ureas markedly affects water rotation and hydrogen bond dynamics in aqueous solution

Femtosecond infrared spectroscopies reveal the substitution pattern of alkylated ureas to be decisive for hydrogen-bond strengths, water rotation, and hydrogen bond fluctuation in the hydration shell

Thermodynamics of Mixing Water with Dimethyl Sulfoxide, as Seen from Computer Simulations

The Helmholtz free energy, energy, and entropy of mixing of eight different models of dimethyl sulfoxide (DMSO) with four widely used water models are calculated at 298 K over the entire composition range by means of thermodynamic integration along a suitably chosen thermodynamic path, and compared with experimental data. All 32 model combinations considered are able to reproduce the experimental values rather well, within RT (free energy and energy) and R (entropy) at any composition, and quite often the deviation from the experimental data is even smaller, being in the order of the uncertainty of the calculated free energy or energy, and entropy values of 0.1 kJ/mol and 0.1 J/(mol K), respectively. On the other hand, none of the model combinations considered can accurately reproduce all three experimental functions simultaneously. Furthermore, the fact that the entropy of mixing changes sign with increasing DMSO mole fraction is only reproduced by a handful of model pairs. Model combinations that (i) give the best reproduction of the experimental free energy, while still reasonably well reproducing the experimental energy and entropy of mixing, and (ii) that give the best reproduction of the experimental energy and entropy, while still reasonably well reproducing the experimental free energy of mixing, are identified

The economic approach to valuation consumer value of environmental quality

These methods form a battery of useful economic approaches for estimation consumer values of environmental quality. All of the methods deserve continuing scientific scrutiny, have room for improvement, and should be employed cautiously and with a critical eye.

Природоінвестування як фактор відтворення регіональних еколого-економічних систем

Залучення інвестицій належної якості у сферу раціонального природогосподарювання є невід’ємним елементом реалізації принципів сталого регіонального розвитку еколого-економічних систем. Під природогосподарюванням зазвичай розуміється матеріально- духовна система, що саморозвивається, яка утворена соціумом і функціонує шляхом включення в неї речовини, енергії, інформації про природне середовище, а також інтелекту і духовності соціуму з метою створення життєпридатних умов для його існування і розвитку, а також для задоволення його інтересів і потреб, співвідносних із законами природних екосистем
