Superhydrophobic sponges based on green deep eutectic solvents for spill oil removal from water
PublicationThe paper described a new method for crude oil-water separation by means of superhydrophobic melamine sponges impregnated by deep eutectic solvents (MS-DES). Due to the numerous potential of two-component DES formation, simple and quick screening of 156 non-ionic deep eutectic solvents using COSMO-RS (Conductor-like Screening Model for Real Solvents) computational model was used. DES which were characterized by high solubility...

Estimating the Impact of Inflow on the Chemistry of Two Different Caldera Type Lakes Located on the Bali Island (Indonesia)
PublicationThis paper is a preliminary attempt to assess the composition of pollutants in two different caldera lakes situated in the Indonesian Archipelago: Batur and Bratan. Both lakes are characterized by largely different physico-chemical regimes; Batur Lake is located in an area that is currently volcanically active, unlike Bratan Lake. The latter is much smaller and shallower than Batur Lake. The concentration of pollutants in the Indonesian...

Towards application of uncertainty quantification procedure combined with experimental procedure for assessment of the accuracy of the DEM approach dedicated for granular flow modeling
PublicationThere is a high demand for accurate and fast numerical models for dense granular flows found in many industrial applications. Nevertheless, before numerical model can be used its need to be always validated against experimental data. During the validation, it is important to consider how the measurement data sets, as well as the numerical models, are affected by errors and uncertainties. In this study, the uncertainty quantification...

Przewodnik Architektoniczny=Architectural Guide=Architekturführer. Gdynia
PublicationGdynia is a unique city that is particularly interesting for architects due to its homogeneous architecture. The city, based on the structure of an earlier fishing village, was entirely designed and built from scratch in the interwar period, as was the case later for cities such as Brasilia and Chandigarh. Today, Gdynia is a modern port town that forms the Tri-City metropolitan area together with Gdańsk, the city of amber, and...

Profilaktyka przeciwpowodziowa w okresie zimowym na zbiorniku Włocławek
PublicationWisła należy do rzek o podwyższonym ryzyku wystąpienia powodzi zatorowych, a problem zlodzenia na rzece Wiśle jest zjawiskiem dobrze udokumentowanym. Przyczyną powstawania zatorów na granicy rzeki i cofki zbiornika jest zmiana warunków przepływu wód, powodująca wcześniejsze zamarzanie zbiornika wraz z późniejszym rozpadem pokrywy lodowej. Najskuteczniejszą metodą kontrolowanej ingerencji w fazę rozpadu pokrywy lodowej jest lodołamanie....

The compositional space of exhaled breath condensate and its link to the human breath volatilome
PublicationBreath analysis is commonly understood to target gaseous or volatile organic compounds (VOCs) for the characterization of different pathologies. Targeted analysis is most effective if a working hypothesis can be based on a plethora of data. The recently published volatilome builds an optimal basis for organizing powerful target sets. However, the origin and pathways of biosynthesis of many VOCs are not known, which complicates...
