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...

Anti-plane shear waves in an elastic strip rigidly attached to an elastic half-space
PublicationWe consider the anti-plane shear waves in a domain consisting of an infinite layer with a thin coating lying on an elastic half-space. The elastic properties of the coating, layer, and half-space are assumed to be different. On the free upper surface we assume the compatibility condition within the Gurtin–Murdoch surface elasticity, whereas at the plane interface we consider perfect contact. For this problem there exist two possible...

Termodynamika oddziaływań substancji tetrafenylowych z wodą w świetle teorii funkcjonału gęstości
PublicationW termodynamice roztworów elektrolitów istotne jest zagadnienie podziału eksperymentalnie wyznaczanych wielkości termodynamicznych na udziały jonowe. Z uwagi na niemożność niezależnego wyznaczenia jonowych wielkości cząstkowych, podział wielkości charakteryzujących elektrolit musi być z konieczności dokonany w oparciu o założenie pozatermodynamiczne. Obecnie przyjmuje się, że najbardziej uzasadnionym teoretycznie i eksperymentalnie...

Mono- and bimetallic (Pt/Cu) titanium(IV) oxide core–shell photocatalysts with UV/Vis light activity and magnetic separability
PublicationTitanium(IV) oxide is one of the most widely investigated photocatalysts. However, separation of nano-sized particulate titania might result in profitless technologies for commercial applications. Additionally, bare titania is almost inactive under the Vis range of solar spectrum due to its wide bandgap. Therefore, the present study aims to prepare novel coreinterlayer- shell TiO2 magnetic photocatalysts modified with metal nanoparticles...
