21. Adsorption of dissolved organic matter in aquatic ecosystems : Effects on composition and reactivity
Abstract : Inland waters receive organic matter from terrestrial ecosystems and in situ production. In transit from land to the ocean, dissolved organic carbon (DOC) may be mineralised to inorganic forms (CO2 and CH4) by microbial degradation and photodegradation. READ MORE

22. Molecular-level dissolved organic matter dynamics in lakes : Constraints on reactivity and persistence
Abstract : Dissolved organic matter (DOM) is a central component of the global carbon cycle. Thus, small changes to the amount of DOM imported, processed and produced within lakes can have a large effect on regional carbon budgets. In addition to being a vital energy source at the base of the aquatic food web, DOM is physico-chemically reactive. READ MORE

24. Iron in the Lena River basin, NE Russia : Insights from microscopy, spectroscopy and isotope analysis
Abstract : Iron is an important mediator of biotic and abiotic processes on the Earth’s surface, being an electron acceptor in organic matter degradation, a surface for organic matter and trace element adsorption, and a required element for enzymatic processes during primary production. Yet, the role of iron as a mediator of carbon and trace element cycling in high latitude, permafrost-dominated regions remains poorly investigated. READ MORE

25. Biocarbon for fossil coal replacement
Abstract : This research aims to provide a full view of knowledge in charcoal production for fossil coal replacement. Charcoal from biomass is a promising material to replace fossil coal, which is using as heating source or reactant in the industrial sector. READ MORE
