The mode of action of the endo ct-1,4 polygalactosaminidase from Pseudomonas sp. 881 on galactesaminooligosaccharides (GOSs) was studied. The enzyme could hydrolyze ct-1,4 polygalactosamine to GOSs by the endo-split manner. Tetraose and longer GOSs were hydrolyzed to galactosaminobiose and ga]actosaminotriose as the final products. Galactosaminomonomer (galactosamine) cou]d not be produced as a...

By taking the advantage of the unique amphiphilic structure of graphene oxide sheets (GOSs), we develop here a new and effective strategy for compatibilizing immiscible polymer blends. With the incorporation of only 0.5 wt % GOSs into immiscible polyamide/polyphenylene oxide (PA/PPO, 90/10) blends, the droplet diameter of the dispersed minor phase (PPO) is dramatically reduced by more than 1 or...

The correlations between process conditions, microstructure, and mechanical properties of additively manufactured components are not fully understood yet. In this contribution, three different hatch strategies used to fabricate rod‐like samples from S316L stainless steel, which further investigated using synchrotron diffraction, optical microscopy, tensile tests. results indicate the presence ⟨...

The cultural and social benefits of green open spaces (GOSs) are frequently disregarded in environmental planning policy. online PPGIS tool, mygreenplace.be, was used to map the ecosystem services (CES) GOSs along Woluwe River. This research aims clarify role CES, spatial qualities travel distance GOSs’ valuation their respective management. analysis revealed that highly valued (CES hot spots) ...
