    Sammanfattning : As the world has woken up to the change in climate in recent years, people's environmental concerns are forcing companies to change and find ways to manufacture products without harming nature. One area of serious concern is the electronics industries where an ever-increasing number of products gets updated with sensors and microcomputers to be part of the internet of things. LÄS MER

  3. 2. Prototype manufacturing of microwave components using plastic 3D printing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Björn Malmquist; [2019]
    Nyckelord :;

    Sammanfattning : The ability to easily customize and produce specialized MW-components for research and industry is a real challenge and the need is identified, as standardized parts have limited use and can limit design freedom. This study aims at exploring if there are simple ways to manufacture rectangular X-band waveguides with operating frequency of 8-12GHz with novel polymer additive manufacturing and chemical metal deposition that can match Computer Numerical Control (CNC) manufactured rectangular metal waveguides in performance.

  4. 3. New Generation Surface treatment for tools : A preliminary study

    Uppsats för yrkesexamina på avancerad nivå, Oorganisk kemi

    Författare :George Massoud; [2013]
    Nyckelord :Kemiteknik; material; ytbehandlingar; ytbehandling; materialutveckling;

    Sammanfattning : The surface finishing technique called black oxidation is currently being used on the tool holders made of low alloyed tool steel produced by Sandvik Coromant. Black oxidation isn’t considered a sufficient technique because it doesn’t make the tool holders look like the quality products that they actually are. LÄS MER

  5. 4. Buried screen-printed contacts for silicon solar cells

    Magister-uppsats, Energi och miljöteknik

    Författare :Ebrahim Jamshidi Gohari; [2012]
    Nyckelord :Laser scribing; Buried Contacts; Screen-printing; screen-printed.;

    Sammanfattning : A Simple way to improve solar cell efficiency is to enhance the absorption of light and reduce the shading losses. One of the main objectives for the photovoltaic roadmap is the reduction of metalized area on the front side of solar cell by fin lines. LÄS MER

  7. 5. Alcoholate corrosion of aluminium in ethanol blends -the effects of water content, surface treatments, temperature, time and pressure

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Jenny Linder; [2012]
    Nyckelord :Alcoholate corrosion; aluminium; ethanol; dry corrosion; surface treatments;

    Sammanfattning : As it becomes more important to replace fossil fuels with alternative fuels, biofuels like ethanol are becoming more commercially used. The increased use of ethanol brings good influences such as lower impact on the environment. However, the use of ethanol can also bring negative effects regarding corrosion of metals. LÄS MER
