Influence of Surface Treatment of Thin-Film Composite Membrane on Separation of Carbon Dioxide from Biogas.
Morávková, Lenka; Kárászová, Magda; Petrusová, Zuzana; Izák, Pavel
2019 - English
The effect of the various wetting procedure on the membrane performance was studied [1]. Spraying is clearly more efficient than spreading water on the top of the membrane with a brush and results in higher methane purity. Spraying ensures a more uniform distribution of the water on the skin layer of the membrane, leading to much higher CO2 permeation through the membrane and higher CH4 content in the retentate stream. Keywords: biogas; separation; carbon dioxide Available in a digital repository NRGL

NMR Metabolomics Study of the Association between Pancreatic Cancer and Diabetes Mellrtus.
Michálková, Lenka; Horník, Štěpán; Sýkora, Jan; Habartová, L.; Setnička, V.
2019 - English
In our study, 1H NMR metabolomics was employed to plasma samples of pancreatic cancer patients, individuals with long-term diabetes mellitus type 2 (lasting more than 5 years) and healthy controls. The NMR analyses were followed by establishing a statistical model based on principal component analysis and discriminant analysis. The aim was to discover differences between these groups and to define a potential biomarker panel. The statistical evaluation of metabolomics-based profiles provided high values of sensitivity and specificity. Subsequently, plasma samples of the risk group, specifically patients with recently diagnosed diabetes mellitus with a duration of <3 years (possible T3cDM), were analysed and the possibility of PC development was predicted. The achieved results showed strong potential of 1H NMR metabolomics to establish a biomarker panel that would facilitate the early diagnosis of PC and the possibility identify diabetic individuals, who are at risk of developing PC.

Dialytic Separation of Anions from DMSO Solution Facilitated by dendritic Receptors.
Cuřínová, Petra; Winkler, Maximilian; Krupková, Alena; Budka, J.; Wun, Ch.N.; Blechta, Vratislav; Červenková Šťastná, Lucie; Sýkora, Jan; Strašák, Tomáš
2019 - English
As the dialytic tubing is impermeable for big molecules of receptor, the anions crossing the barrier of dialytic tubing to form complex with the receptor stay entrapped inside and can be removed from the solution. NMR methods were used to study the complexation properties of given receptors as well as to determine the concentration changes during dialytic experiments. Keywords: anions; receptor; dialytic experiments Available in a digital repository NRGL

Charge Transport in Single Oligophenylene Molecular Wires with Different Anchoring Groups
Hromadová, Magdaléna; Kolivoška, Viliam; Šebera, Jakub; Sebechlebská, Táňa; Gasior, Jindřich; Nováková Lachmanová, Štěpánka; Mészáros, G.; Lindner, M.; Mayor, M.; Valášek, M.
2019 - English
This work compares single molecule conductance measurements of selected organic systems containing identical oligophenylene molecular wires and different tripodal anchoring groups. Single molecule conductance G was obtained by a scanning tunneling microscopy break junction technique complemented by theoretical calculations based on the density functional theory and non-equilibrium Green’s function formalism. Two molecules were compared where the same oligophenylene wire is connected to one of the electrodes via a tripod substituted on each leg by a thiol group either in the meta or para position. By combined experimental and theoretical analysis it was possible to confirm that single molecule conductance in the metal-molecule-metal junction of both molecules corresponds to a fully extended molecular wire, which is attached to one of the electrodes by all three thiolate bonds of the tripod. Experimental results confirmed that G value of meta-connected molecules is lower than that of para, whereas junction formation probability was higher for meta functionalization.
