21. Novel methods to synthesize aliphatic polyesters of vivid architectures
Abstract : Cross-linked films of ε-caprolactone (CL) and 1,5-dioxepan-2-one (DXO) having various mole fractions of monomers and different cross-link densities were prepared using 2,2’-bis-(-caprolactone-4-yl) propane (BCP) as cross-linking agent and Sn(Oct)2 as catalyst. Reaction parameters were examined to optimize the film-forming conditions. READ MORE

24. Tuning Properties of Surfaces and Nanoscopic Objects using Dendronization and Controlled Polymerizations
Abstract : In this study, dendronization and grafting via controlled polymerization techniques, atom transfer radical polymerization (ATRP) and ring-opening polymerization (ROP), have been explored. Modification of surfaces and cellulose using these techniques, which enable grafting of well-defined polymer architectures, has been investigated. READ MORE

25. Growth and morbidity in extreme preterm born infants
Abstract : Background: Rapid development in neonatal care during the past years has significantly improved long-term survival of extreme preterm born (EPB) infants creating a population of children with a high frequency of disabilities. Being lighter and shorter, as compared to full-term (FT) born child, predisposes the EPB infants to intensive nutritional interventions aiming for growth-promoting effect. READ MORE
