  2. 1. Computational studies of photodynamic drugs, phototoxic reactions and drug design

    Author : Klefah Abrahem Klefah Musa; Leif Eriksson; Nino Russo; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NSAIDs; fluoroquinolone; photodegradation; phototoxicity; drug design; DFT; TD-DFT; Biophysical chemistry; Biofysikalisk kemi; Chemistry; Kemi;

    Abstract : The most important criterion when designing new drugs or improving old ones in order to prevent side effects or at least diminish them is drug safety. Treatment of all diseases generally needs use of either topical application or systemic medications (transported in the blood) during a certain period of time. READ MORE

  4. 2. Solar-based physicochemical-biological processes for the treatment of toxic and recalcitrant effluents

    Author : Tamer Essam; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; combined process; biodegradaiton; phenolics; phenol; Advanced Oxidation Processes; Photodegradation; photolysis;

    Abstract : Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater treatment.

  5. 3. Graphene-based nanocomposites for electronics and photocatalysis

    Author : Ebrahim Chalangar; Håkan Pettersson; Magnus Willander; Omer Nour; Maria Messing; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Zinc oxide; Silver iodine; Plasmonics; Nanocomposites; Conjugated electronics; Photocatalysis; Photodegradation;

    Abstract : The development of future electronics depends on the availability of suitable functional materials. Printed electronics, for example, relies on access to highly conductive, inexpensive and printable materials, while strong light absorption and low carrier recombination rates are demanded in photocatalysis industry.

  6. 4. Reactive dissolved organic carbon dynamics in a changing environment : Experimental evidence from soil and water

    Author : Balathandayuthabani Panneer Selvam; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic carbon; DOC; Photodegradation; Biodegradation; DOC reactivity;

    Abstract : Dissolved organic carbon (DOC) is the major form of organic carbon in aquatic ecosystems. Biological and photochemical degradation of DOC are major causes of greenhouse gas emissions from aquatic ecosystems. READ MORE

  7. 5. Fabrication and Characterization of Composite TiO2/Carbon Nanofilms with Enhanced Photocatalytic Activity

    Author : Raja Sellappan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TiO2; carbon; photoluminescence; photodegradation; recombination.; Photocatalysis;

    Abstract : The work presented in this thesis is dedicated to fabrication and characterization of an efficient thin film photocatalyst for environmental cleaning and solar fuel applications. Because of its simplicity and reproducible fabrication, the chosen combination of nanometer thin titania and carbon films serves also as a model system for a wider class of photoactive materials.
