Photocatalytic degradation of bisphenol A induced by dense nanocavities inside aligned 2D-TiO2 nanostructures

Bakardjieva, Snejana; Fajgar, Radek; Jakubec, Ivo; Koci, Eva; Zhigunov, Alexander; Chatzisymeon, Efthalia; Davididou, Konstantina

The preparation of materials with aligned porosity in the nanometer range is of technological importance for a wide range of applications in molecular filtration, biomaterials and catalysis. Herein we present the advantages offered by cryo – lyophilisation technique as a smart and green non-standard concept to produce dense regular polyhedral…

Tuning the interphase adhesion in high-density polyethylene–silica nanocomposites with ionic liquids

Donato, Katarzyna Z.; Donato, Ricardo K.; Zhigunov, Alexander; Mauler, Raquel S.; Schrekker, Henri S.

This work addresses the use of ionic liquids (ILs) as multifunctional additives in the formation of high-density polyethylene (HDPE)/sol–gel silica nanocomposites via the melt-mixing process. Different approaches for nanocomposite formation were studied and compared, including (1) silica modification with ILs during the sol–gel process and further addition into the polymer…

Strong synergistic improvement of mechanical properties in HDPE/COC blends with fibrillar morphology

Ostafinska, Aleksandra; Vackova, Tatana; Slouf, Miroslav

High-density polyethylene/cycloolefin copolymer (HDPE/COC) blends with fibrous morphology were prepared. Mechanical properties in the whole concentration range were measured in both macroscale (tensile measurements) and microscale (microindentation hardness testing). Strong improvement of mechanical performance was observed namely for the blends with soft HDPE matrix reinforced with the stiff…

How Fluorescent Tags Modify Oligomer Size Distributions of the Alzheimer Peptide

Wägele, Jana; De Sio, Silvia; Voigt, Bruno; Balbach, Jochen; Ott, Maria

Within the complex aggregation process of amyloidogenic peptides into fibrils, early stages of aggregation play a central role and reveal fundamental properties of the underlying mechanism of aggregation. In particular, low-molecular-weight aggregates of the Alzheimer amyloid-β peptide (Aβ) have attracted increasing interest because of their role in cytotoxicity and neuronal…

Structure evolution during order–disorder transitions in aliphatic polycarbonate based polyurethanes. Self-healing polymer

Matějka, Libor; Špírková, Milena; Dybal, Jiří; Kredatusová, Jana; Hodan, Jiří; Zhigunov, Alexander; Šlouf, Miroslav

The aliphatic polycarbonate based polyurethanes (PU) from poly(hexamethylene) carbonate diol (PC), hexamethylenediisocyanate and hexanediol were synthesized, characterized and designed as promising self healing polymers. The symmetrical linear PU structure containing the hexamethylene sequences results in a high degree of ordering and strong superstructures, manifested by a high crystallinity of…

Temperature-Induced Self-Assembly of the Group B Streptococcus (GBS) Fusion Antigen GBS-NN

Rose, Fabrice; Roovers, Silke; Fano, Mathias; Harloff-Helleberg, Stine; Kirkensgaard, Jacob J.K.; Hejnaes, Kim; Fischer, Per; Foged, Camilla

Group B Streptococcus (GBS) is a leading cause of serious bacterial neonatal infections worldwide, which provides an unmet medical need for a globally effective vaccine. The recombinant GBS fusion antigen GBS-NN contains the N-terminal regions of the GBS Rib and Alpha C proteins. It shows promising immunogenicity eliciting protective immunity…

Conduction mechanism in polymeric membranes based on PEO or PVdF-HFP and containing a piperidinium ionic liquid

Elamin, Khalid; Shojaatalhosseini, Mansoureh; Danyliv, Olesia; Martinelli, Anna; Swenson, Jan

Two types of polymer electrolyte membranes were prepared using poly(ethylene oxide) (PEO) and poly(vinylidene difluoride-co-hexafluoropropylene) (PVdF-HFP), with different amounts of the ionic liquid N-methyl-N-propylpiperidinium bis(trifluoromethane-sulfonyl)imide () added. The results from differential scanning calorimetry and conductivity measurements show that in the case of…
