The effective nonsinusoidal expression for the current-phase relation with an additional half harmonic term is used for the double-barrier junction. Devices with inhomogeneous double-barrier junctions show a characteristic feature: for fixed and not too high superconducting loop inductance values, transition from irreversible to reversible magnetic behavior can be induced by increasing the difference in the Josephson coupling of the two junctions.

“The use of polymeric materials as the carrier in the controlled release of guest molecules has become an important research area in the polymeric materials science, because of their advantages of the safety, efficacy and patient convenience. One of them, star amphiphilic polymer can self-assemble into supermolecular structure (polymer micelles) by the balance of hydrophilic and hydrophobic interaction. In this study, star amphiphilic copolymer consisting of hydrophobic and biodegradable poly(E-caprolactone)

(PCL) and hydrophilic poly(ethylene oxide) (PEO) blocks were synthesized by two-step ring-opening polymerization. 3-Methyladenine datasheet The resultant polymer was characterizated by FTIR, H-1-NMR, and DSC to determine its chemical structure. The morpholoy of the polymer micelles was analyzed by TEM. Using star-PCL-b-PEO as carriers and congo red as model guest molecules, the encapsulation and release properties were investigated by UV-visable

“Extraction of catalytically active biomolecules using ionic liquid-based aqueous two-phase systems (IL-based ATPS) composed Napabucasin purchase of the IL Ammoeng(TM) 110 and K(2) HPO(4)/KH(2)PO(4) represents a powerful tool for the integration of several process steps into one unit operation within downstream processing. The technique can be used in order to combine the purification of active enzymes with the performance of enzyme-catalysed reactions. However, a fundamental understanding of the driving forces which are involved in the partitioning of proteins between the two phases is still lacking. By investigating the distribution of four model proteins at varying system characteristics of the IL-based ATPS, we found a combination of different interactions between the proteins and the ionic liquid to be responsible for the enrichment within the IL-containing upper phase. Among these, the proteins’ charge as well as the molecular weight is of major importance. Therefore, we propose the electrostatic interaction between the charged amino acid residues at a protein’s surface and the positively charged IL-cation to be the main driving force of the extraction process.
