1. Spray-Dried Powders for Inhalation : Particle Formation and Formulation Concepts
Abstract : Spray drying is a method with a high potential in the preparation of protein particles suitable for pulmonary delivery. However, surface induced denaturation of bio-molecules during atomization and subsequent drying can be substantial and it is therefore important to develop new formulation concept for concurrent encapsulation and stabilization of proteins during spray drying.

2. Modeling of new particle formation and growth in the atmospheric boundary layer
Abstract : Atmospheric aerosols affect climate, but to what degree still remains one of the largest uncertainties in global climate models. To improve the representation of aerosols in future climate models we need a greater understanding of aerosol processes. READ MORE

3. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass
Abstract : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. READ MORE

4. The relationship between fly ash chemistry and the thermal formation of polychlorinated pollutants during waste incineration
Abstract : The thermal formation of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), and naphthalenes (PCNs) is a major problem in waste incineration. Ideally, rather than relying on air cleaning systems and treatment techniques, their formation should be minimized or, if possible eliminated. READ MORE

5. Fine particle emissions and slag formation in fixed-bed biomass combustion : aspects of fuel engineering
Abstract : There is a consensus worldwide that the share of renewable energy sources should be increased to mitigate climate change. The strive to increase the renewable energy fraction can partly be met by an increased utilization of different biomass feedstocks. READ MORE
