  1. 1. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reaction

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Milda Grikainyte; [2022]
    Nyckelord :Water-gas shift; catalyst; chemical engineering; Chemistry;

    Sammanfattning : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. LÄS MER

  3. 2. Vilka potentiella behandlingsalternativ finns det mot bakteriella infektionssjukdomar som ligger i fas 2-3 studier eller som man bedriver forskning på?

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Linnea Johansson; [2018]
    Nyckelord :antibiotika; nanopartiklar; nanopartikel; resistens; antibiotikaresistens; ENABLE; ENABLE-projektet;

    Sammanfattning : Resistance against antibiotics has become a global world problem. The effect of antibiotics is affected by the resistant bacteria and they cause infections that are difficult to treat. This is a major burden on the healthcare and leads to increased mortality. Globally, about 700,000 people die each year because of antibiotic resistance. LÄS MER

  4. 3. Adhesion of CVD coatings on new cemeted carbides

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Eric Bojestig; [2016]
    Nyckelord :cemented carbide; adhesion; alternative binder phase; CVD coating; hard metal;

    Sammanfattning : Steel turning inserts cemented carbides have a binder phase consisting of cobalt (Co). However, in recent years a study from the United States National Toxicity Program (NTP) found that cobalt powder is carcinogenic upon inhalation. The European Union's REACH have therefore also classified cobalt powder as carcinogenic upon inhalation. LÄS MER

  5. 4. Vattenkvaliténs påverkan på bladmögelsfungicider : bekämpningseffekt i laboratoriemiljö

    Magister-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Johannes Eriksson; [2016]
    Nyckelord :vattenkvalitet; Phytophthora infestans; Potatisbladmögel; pH; hårdhet; Fe²⁺;

    Sammanfattning : The majority of pesticides used in agriculture is mixed with water prior to application and the rate of water widely exceeds the rate of pesticides. Water from different sources has different characters such as pH, water hardness (°dH) and iron content. That these different characters affect some sensitive pesticides is well known. LÄS MER

  7. 5. Gradient formation in cemented carbides with 85Ni:15Fe-binder phase

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Niklas Larsson; [2015]
    Nyckelord :cemented carbide; alternative binderphase; sintering; gradient; hard metal;

    Sammanfattning : In today’s inserts used for metal cutting the binder phase consists of cobalt (Co).However, EU’s REACH programme and the U.S’s National Toxicity Programme(NTP) classified Co as toxic/carcinogenic. Therefore, there is a strong need toinvestigate alternative binder phases. LÄS MER
