Effect of choline chloride based natural deep eutectic solvents on aqueous solubility and thermodynamic properties of acetaminophen
PublicationIn this work, natural deep eutectic solvents (NADESs) containing choline chloride as hydrogen bond acceptor and 1,2-propanediol, malic acid and tartaric acid as hydrogen bond donors have been synthesized and applied to enhance the aqueous solubility of model sparingly water-soluble drug – acetaminophen. The results indicate that the greatest impact on the solubility of acetaminophen have deep eutectic solvents based on 1,2-propanediol...

New Simple and Robust Method for Determination of Polarity of Deep Eutectic Solvents (DESs) by Means of Contact Angle Measurement
PublicationThe paper presents a new method for evaluating the polarity and hydrophobicity of deep eutectic solvents (DESs) based on the measurement of the DES contact angle on glass. DESs consisting of benzoic acid derivatives and quaternary ammonium chlorides–tetrabutylammonium chloride (TBAC) and benzyldimethylhexadecylammonium chloride (16-BAC)—in selected molar ratios were chosen for the study. To investigate the DESs polarity, an optical...

Solubility enhancement of metronidazole using natural deep eutectic solvents: Physicochemical and thermodynamic studies
PublicationThis research aimed to explore the utility of natural deep eutectic solvents (NADES) as the co-solvents for slightly water-soluble metronidazole (MNZ). After testing 70 wt% (percentage by weight) aqueous mixtures of seven NADESs, it was found that MNZ had the highest solubility in water solutions of NADES composed of choline chloride (ChCl) and citric acid (CA). The solubility of MNZ (expressed as 103 mol fraction) increased with...

Skutki zanieczyszczenia środowiska związane z generowaniem energii
PublicationNa całym świecie (dane z 2020 roku) spalanie paliw kopalnych takich jak węgiel, ropa naftowa i gaz ziemny dostarczyło ok. 84% całej zużywanej energii pierwotnej. W przypadku Polski konwencjonalne źródła energii stanowiły ponad 93%. Gigantyczne zużycie konwencjonalnych paliw powoduje wielkie straty w środowisku, objawiające się m.in. skażeniem powietrza, które stanowi największe środowiskowe zagrożenie dla zdrowia ludzi na świecie...
