The mutualistic symbiosis between stony corals and unicellular algae of the family Symbiodiniaceae forms the base of coral reef ecosystems. However, anthropogenic stressors, such as rising seawater temperatures, cause a breakdown of the coral-algal symbiosis, so-called coral bleaching, which leads to mass mortalities…

Industrial oxygen-delignified and fully-bleached hardwood kraft pulps were treated with chemicals to provoke carbohydrates depolymerisation: ozone, hypochlorous acid, and cellulase. The degrees of polymerisation (DP) of cellulose obtained by pulp viscosity measurement in Cuen and by size-exclusion chromatography after…

Human hair is a keratin-based fiber with mechanical properties relevant to load-bearing biomaterials; however, its smooth cuticle limits fiber-fiber cohesion during textile-style processing. This study examines how controlled chemical decuticularization influences surface morphology and tensile behavior of intact human…

Variation in fluorescence intensity from rhodamine 6G dye was investigated. A small volume of dye solution was optically excited with a 400 µW, 532nm wavelength cw-laser light. The dye was dissolved in methanol and glycerol for a concentration of 10mg/ml. With the optical excitation, initially the fluorescence…

'Paola Lanzafame'] The prospects, needs and limits in current approaches in catalysis to accelerate the transition to an e-chemistry, where this term indicates a novel fossil fuel-free chemical production, are discussed. It is suggested that an e-chemistry is a necessary element of the transformation to meet the…

When whitewater circuits in the paper industry are closed, organic compounds accumulate and cause adverse production problems, such as the formation of slime and pitch. Since wood-free whitewater is usually a mixture of additives for paper production and an efficient cost-effective purification technology for their…
