  1. 1. Biomass Energy Systems and Resources in Tropical Tanzania

    Författare :Lugano Wilson; Weihong Yang; Wlodzimierz Blasiak; Truls Liliedahl; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tanzania; Tropical Biomass Energy; High Temperature Gasification HTAG ; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : Tanzania has a characteristic developing economy, which is dependent on agricultural productivity.  About 90% of the total primary energy consumption of the country is from biomass.  Since the biomass is mostly consumed at the household level in form of wood fuel, it is marginally contributing to the commercial energy supply.

  2. 2. CO2 Separation with Ionic Liquids -Property, Gas solubility and Energy consumption

    Författare :Yujiao Xie; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Ionic liquids (ILs) have shown great potential to be used as liquid absorbents for CO2 capture because of its advantages, such as non-volatility, functionality, high CO2 solubility and lower energy requirements for regeneration. A significant amount of research has been carried out, but most of them are on the synthesis of novel ILs and the measurements of CO2 solubility in ILs. LÄS MER

  3. 3. Quantum Chemical Studies of Chemotherapeutic Drug Cisplatin : Activation and Binding to DNA

    Författare :Johan Raber; David van der Spoel; Paolo Carloni; Uppsala universitet; []
    Nyckelord :Quantum chemistry; cisplatin; quantum chemistry; DNA; density functional theory; activation; JM118; substitution reaction; Platinum; guanine; adenine; cytostatic drug; aquation; anation; activation; Kvantkemi;

    Sammanfattning : The serendipitous discovery of the potent cytotoxic properties of cisplatin brought about a revolution in the treatment of certain types of cancer, but almost fifty years later, there still remain unknown areas in the chemistry of cisplatin. There are questions regarding which form of the drug reaches its DNA target, or why certain DNA sequences are more preferred than others for reaction with cisplatin. LÄS MER

  4. 4. Norbornadienes for Solar Thermal Energy Storage and New Applications

    Författare :Ambra Dreos; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; molecular logic; Solar energy; molecular switch- es; energy conversion; quadricyclane; molecular keypad locks; norbornadiene;

    Sammanfattning : 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.

  5. 5. Integrating Heat Pumps into Smart Grids

    Författare :David Fischer; Björn Palm; Georges Laurent; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Sammanfattning : Transforming our energy system towards 100% renewable energy sources requires radical changes across all energy sectors. Heat pumps as efficient heat generation technology link the electricity and heat sector. From 2010 to 2015 between 750,000 and 800,000 heat pumps have been sold every year across Europe. LÄS MER
