16. Manufacturing and characterization of nanomaterials for low-temperature sintering and electronics thermal management applications
Sammanfattning : Nanotechnology is expected to have a significant impact on the long-term development within and across many disciplines. While offering potential improvements in energy efficiency and reduced energy and materials consumption, nanomaterials are at the centre of the cutting-edge technologies and sustainable manufacturing processes era with near half of the products in the next period of 10 years expected to embed nanoscale solutions.

17. Estimating the Air-Water Gas Transfer Velocity during Low Wind Conditions
Sammanfattning : The abundances of atmospheric carbon dioxide, CO2, and methane, CH4, are increasing. These increases affect e.g., the global carbon cycle and the climate both regionally and globally. LÄS MER
18. State-of-the-art Integrated Refrigeration Systems in Supermarkets : An Energy Efficiency Evaluation Based on Field Measurements Analysis and Computer Simulations
Sammanfattning : Supermarkets have become a vital feature of modern society. However, they have significant impact on the environment due to the large amount of refrigerants needed in the refrigeration system, and due to the large energy use in the supermarket, they are the commercial buildings with highest energy intensity.

19. The role of biogeophysical feedbacks and their impacts in the arctic and boreal climate system
Sammanfattning : The physical environment in the northern high latitudes including the Arctic cryosphere has undergone dramatic changes due to anthropogenic greenhouse gas warming, which since pre-industrial times has been twice or more the rate of global mean warming. Global climate models predict that this accelerated warming will continue for at least the next few decades. LÄS MER
20. Reduction of prime energy consumption by ground source heat pumps in a warmer world
Sammanfattning : Much of the energy used worldwide is supplied by fossil fuels (~85 %) while renewable energy sources supply approximately 6 %. A sustainable future urgently requires worldwide efforts to reduce primary energy consumption and increase use of renewable energy sources. LÄS MER
