1. Thermodynamic Cycles for Low- and High-Temperature Waste Heat Recovery from Heavy-Duty Engines
Abstract : To reduce the environmental impact of heavy-duty vehicles, it is critical to reduce their CO2 emissions by improving the engine efficiency. A promising way to do this is by extracting waste heat from the engine during operation and converting it into useful work. READ MORE

2. Magnetic Refrigeration for Near Room-Temperature Applications
Abstract : Refrigeration plays a crucial role in many different sectors and consumes about 17% of the electricity produced globally. This significant energy consumption implies large share of refrigeration in primary energy consumption and other environmental impacts. READ MORE

3. SiC-FET Gas Sensors Developed for Control of the Flue Gas Desulfurization System in Power Plants Experimental and Modeling : Experimental and Modeling
Abstract : Electricity and power generation is an essential part of our life. However, powergeneration activities also create by-products (such as sulphur oxides, nitrogen oxides,carbon monoxide, etc), which can be dangerous when released to the atmosphere. READ MORE

4. Glaciers and climate in northern Sweden during the 19th and 20th century
Abstract : Our understanding of the climate of northern Sweden during the late Holocene is largely dependent on proxy-data series. These datasets remain spatially and temporally sparse and instrumental series are rare prior to the mid 19th century. READ MORE

5. SBR-technology - use and potential applications for treatment of cold wastewater
Abstract : Biological nutrient removal is used as an indicator of SBR performance at nine different SBRplants operated for a long period at low water temperatures (5 – 10oC). Typically needed aeratedSRT (Solids Residence Time) for complete nitrification is found to be in the range of 6 – 10 days. READ MORE
