1. Metal-exchanged zeolites for NH3-SCR applications - Activity and Deactivation studies
Abstract : Emissions of nitrogen oxides (NOX) formed during the burning process in internal combustion engines is a major contributor to global air pollutions. One effective way to reduce NOX in lean environments, i.e. oxygen excess is selective catalytic reduction with ammonia (NH3-SCR). READ MORE

2. Multifunctional Carbon Foams by Emulsion Templating : Synthesis, Microstructure, and 3D Li-ion Microbatteries
Abstract : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. READ MORE

3. Direct conversion of methane-to-methanol: transition-metal dimer sites in small-pore zeolites: First-principles calculations and microkinetic modeling
Abstract : Direct conversion of methane to methanol is a highly desired reaction. Partially oxidizing methane into a liquid fuel at ambient temperature and pressure would enable utilization of natural gas and biogas to a much larger extent than what is possible today. READ MORE

4. Behavior of iron-based oxygen carriers at deep reduction states
Abstract : Oxygen carriers have an important role as bed materials in both common circulating fluidized bed combustion unit (also known as oxygen-carrier-aided combustion, OCAC) and in various chemical looping processes. Contrary to conventional bed materials, e.g., sand, oxygen carriers are capable of transferring both oxygen and heat. READ MORE

5. Norbornadienes for Solar Thermal Energy Storage and New Applications
Abstract : The energy demand worldwide is steadily increasing, therefore it is fundamental to efficiently utilise renewable energy resources. Energy storage technologies are partic- ularly relevant in order to be able to exploit renewable energy resources such as solar energy, since these are typically intermittent and not evenly distributed.
