Journal ArticleDOI
Effects of Composition of Oligo(ethylene glycol)-Based Mixed Monolayers on Peptide Grafting and Human Immunoglobulin Detection
TL;DR: The specificity toward IgG was optimal for peptides grafted on SAMs prepared from 10% EG6NH2 precursor solution, even though this surface did not have the highest number of peptides per unit area.
Journal ArticleDOI
Changes in milk fat globules and membrane lipids under the shear fields of microfiltration and centrifugation
Annamari Jukkola,Sanna Hokkanen,Tero Kämäräinen,Riitta Partanen,Antti Heino,Orlando J. Rojas +5 more
TL;DR: In this article, the authors compared the efficiency of centrifugal and microfiltration separation of milk fat globules (MFG) from bovine cream and the changes that take place in the corresponding lipid membranes (MFGM).
Journal ArticleDOI
Effects of Chloride Concentration on the Water Disinfection Performance of Silver Containing Nanocellulose-based Composites.
Janika Lehtonen,Jukka Hassinen,Riina Honkanen,Avula Anil Kumar,Heli Viskari,Anu Kettunen,Nikolaos Pahimanolis,Thalappil Pradeep,Orlando J. Rojas,Olli Ikkala +9 more
TL;DR: Low-cost nanocellulose-aluminium oxyhydroxide nanocomposites functionalized with silver nanoparticles provide insights for designing freshwater purification systems that utilize silver-releasing materials and indicate that an increase of chloride concentration leads to a substantial reduction of antibacterial efficiency, even within chloride concentrations found in freshwaters.
Journal ArticleDOI
Regioselective and water-assisted surface esterification of never-dried cellulose: nanofibers with adjustable surface energy
Marco Beaumont,Marco Beaumont,Caio G. Otoni,Bruno D. Mattos,Tetyana V. Koso,Roozbeh Abidnejad,Bin Zhao,Anett Kondor,Alistair W. T. King,Orlando J. Rojas,Orlando J. Rojas +10 more
TL;DR: The proposed acylation is introduced as a sustainable approach that benefits from the presence of water and affords a high chemical substitution selectivity and is well suited for application at high-solid content.
Journal ArticleDOI
Plasticized Cellulosic Films by Partial Esterification and Welding in Low-Concentration Ionic Liquid Electrolyte
TL;DR: Inspired by the composition and structure of wood’s cell walls, phenolic acids are used to endow cellulosic fibers with new properties that contribute to the development of the next-generation green, renewable, and biodegradable films for packaging applications.
