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

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Milda Grikainyte; [2022]
   Keywords : Water-gas shift; catalyst; chemical engineering; Chemistry;

   Abstract : 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. READ MORE

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

   University essay from Uppsala universitet/Tillämpad materialvetenskap

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

   Abstract : 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. READ MORE

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

   University essay from SLU/Dept. of Forest Mycology and Plant Pathology

   Author : Johannes Eriksson; [2016]
   Keywords : vattenkvalitet; Phytophthora infestans; Potatisbladmögel; pH; hårdhet; Fe²⁺;

   Abstract : 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. READ MORE

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

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Niklas Larsson; [2015]
   Keywords : cemented carbide; alternative binderphase; sintering; gradient; hard metal;

   Abstract : 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. READ MORE

6. 5. Evaluation of the efficiency of treatment techniques in removing perfluoroalkyl substances from water

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Sandra Lundgren; [2014]
   Keywords : PFAS; removal efficiency; MIEX®; iron III chloride; Powdered activated carbon; nanofiltration membrane; dissolved organic carbon;

   Abstract : Perfluoroalkylated substances (PFASs) are a group of synthetic compounds that have gained growing attention due to their environmental persistence, toxicity and their potential to bioaccumulate. Even though PFASs are not occurring naturally in our environment, they are globally distributed and can be found ubiquitously in air, water, soil, wildlife as well as in humans. READ MORE
