1. 1. Innovative treatment technologies for PFAS-contaminated water - Utilizing foam partitioning and exploring electrochemical oxidation

   Författare :Sanne Smith; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The presence of per- and polyfluoroalkyl substances (PFAS) in the aquatic environment has become a global cause for concern. PFAS are persistent anthropogenic chemicals, and certain PFAS are known to be mobile, bioaccumulative and toxic. LÄS MER

3. 2. Modelling of the electrochemial treatment of tumours

   Författare :Eva Nilsson; KTH; []
   Nyckelord :cancer; direct current; dose planning; electrochemical treatment; electrotherapy; mathermatical modelling; tumour;

   Sammanfattning : The electrochemical treatment (EChT) of tumours entails thattumour tissue is treated with a continuous direct currentthrough two or more electrodes placed in or near the tumour.Promising results have been reported from clinical trials inChina, where more than ten thousand patients have been treatedwith EChT during the past ten years.

4. 3. Influence of electrode material and stochastic factors on the performance and microbial community assembly in microbial electrochemical systems

   Författare :Marie Abadikhah; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microbial community assembly; bioanode; biocathode; biochemical system;

   Sammanfattning : Microbial electrolysis cells (MECs) are systems with microbial communities in the form of biofilms on electrode surfaces. The electrogenic bacteria in the anode biofilm act as catalysts for the oxidization of organic compounds, leading to release of electrons, generation of electrical current, and production of hydrogen and methane at the cathode.

5. 4. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications

   Författare :Francesco Montecchio; Klas Engvall; Roberto Lanza; Ernest Blatchley III; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOP; UV; photocatalysis; ozone; air pollution; VOC abatement; reactor design; reactor modelling; photocatalyst support; electrochemical treatment; electrochemical etching; irradiation modelling; kinetics modelling; fluid dynamics simulation; prototype; full-scale; CFD simulation; Chemical Engineering; Kemiteknik;

   Sammanfattning : Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. LÄS MER

7. 5. Development of electrochemical sensor and biosensor platforms : detection of therapeutic drugs and heavy metal ions

   Författare :Sereilakhena Phal; Solomon Tesfalidet; Britta Lindholm-Sethson; William Siljebo; Pankaj Vadgama; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sensors; electrode surface modification; electrochemical immitance spectroscopy; square wave anodic stripping voltammetry; singular value decomposition; therapeutic drugs; heavy metals;

   Sammanfattning : Electrochemical sensors and biosensors combine the sensitivity of electroanalytical methods with the selectivity of a sensor or biosensor surface. The chemical or biochemical component (receptor) in the sensor recognizes an analyte and produces an electrical signal which is proportional to the analyte concentration. LÄS MER
