The paper deals with the cholesterol–cyclosporine A (Chol–CsA) monolayers at the air/water interface investigated using the Langmuir trough coupled with the Brewster’s angle microscopy. The compressed films were transferred onto the PEEK polymer support by means of the Langmuir–Blodgett technique. To improve molecules adhesion and organization the ...

A commercially available screen-printed carbon electrode coated with carbon nanofibers (SPCE/CNFs) and differential-pulse adsorptive stripping voltammetry (DPAdSV) were used to determination of caffeine. The process of electrochemical oxidation of caffeine in 0.1 mol L−1 sulfuric acid at the SPCE/CNFs surface was investigated by cyclic voltammetry ...

Accumulation of polyphenolic antioxidants at the oil–water interfaces of lipid-based emulsions is crucial to improve their oxidative stability. Polyphenolic antioxidants are added to lipid-based emulsions to minimize the lipid peroxidation reaction, a radical reaction that produces harmful products and undesirable off-flavors, and because of their ...

The exploration and evaluation of new composites possessing both processability and enhanced hydrogen storage capacity are of significant interest for onboard hydrogen storage systems and fuel cell based electric vehicle development. Here we demonstrate the fabrication of composite membranes with sufficient mechanical properties for enhanced hydrog...

The sorption of n-heptane in the SBA-3 silica was investigated using positron annihilation lifetime spectroscopy (PALS). The PALS technique allows to study in situ evolution of pore filling by the n-alkane. In the dry SBA-3, the free volumes attributed to the silica skeleton, micropores, mesopores as well as intergranular spaces can be distinguishe...

Silica monoliths loaded with hexacyanoferrate (HCF) nanoparticles were designed and synthesized to selectively remove Cs+ ions from an aqueous saline solution within a continuous flow set-up. The decontamination and hydrodynamic efficiency of this smart material was compared to other granularly supported HCF. Finally, a thermal treatment was applie...

For many years, there has been debate, both in the scientific and user communities, on the influence of the flow pattern on the adsorption behaviour of a filter filled with activated carbon. Some authors reported significant differences in the breakthrough times of gases and vapours, whereas others did not. Some laboratories are switching to testin...

The aim of presented research concerned synthesis of a novel lignosulfonate-based sorbent and its application in batch adsorption tests related to removal of an active pharmaceutical ingredient (ibuprofen). Obtained hybrid material was thoroughly characterized with respect to morphology, porosity (BET method and BJH algorithm), electrokinetic stabi...

Here we present an analysis of the force-transmission error for a commercial gravimetric sorption analyzer that applies equally to single-sinker densimeters. Gravimetric sorption analyzers are commonly used for the investigation of gas adsorption on porous materials (e.g., zeolites) with a simultaneous density measurement of the sample gas. The key...

An amino acid ionic liquid (AAIL) was immobilized into a few kinds of mesoporous silica supports, namely MCM-41 and SBA-15, calcined or not calcined by an impregnation method. 1-Ethyl-3-methylimidazolium lysine ([EMIM][Lys]) was synthesized and employed as an AAIL. CO2 adsorption experiments were then carried out using the [EMIM][Lys]-loaded mesopo...
