  1. 1. Computational study of the photophysical properties of two related photosensitizer proteins

    University essay from KTH/Kemi

    Author : Benjamin Fégeant; [2023]
    Keywords : Photosensitizer proteins; QM MM; photophysics; molecular dynamics; computational protocol for protein preparation; Fotosensibiliserande proteiner; QM MM; fotofysik; molekylär dynamik; beräkningsprotokoll för förberedelser av proteiner;

    Abstract : Den ökande koldioxidhalten i atmosfären har lett till ett ökat intresse för användning av solljus, ett exempel är inom kemi. Att använda ljus i kemi kan leda till nya och intressanta kemiska reaktioner och kan tillämpas i användningsområden som exempelvis fotokatalys och fotovoltaik. READ MORE

  3. 2. Enhancing the degradation rate of microplastics and organizing a study visit about sustainability

    University essay from KTH/Lärande

    Author : Marianne Al-Ghorabi; [2020]
    Keywords : Accommodation; assimilation; Fenton reaction; microplastics; polypropylene; polystyrene; proximal development zone; study visit; visible light photocatalysis; zinc oxide nanorods; Ackommodation; assimilation; den proximala utvecklingszonen; Fenton reaktion; fotokatalys med synligt ljus; mikroplast; polypropalen; polystyren; studiebesök; zinkoxid nanorör.;

    Abstract : Microplastics take hundreds to thousands of years to degrade in nature, and pose a threat to the environment. A photocatalytical degradation method have been developed to take advantage of solar light to degrade microplastics, however it takes several months to degrade microplastics with the process.

  4. 3. Carbon dioxide utilization in the food industry. Synthesis of carbohydrates and their precursors via photocatalytic reduction of carbon dioxide

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Alex Mosquera Canchingre; [2020]
    Keywords : CO2 utilization; photocatalysis; carbohydrates; artificial photosynthesis; sustainable food industry; CO2-användning; fotokatalys; kolhydrater; artificiell fotosyntes; hållbar livsmedelsindustri;

    Abstract : Today’s society strives to eliminate the carbon dioxide (CO2) emissions, which is the main greenhouse gas emitted through anthropogenic activities and contributes to climate change. In this project utilization of CO2 emissions from waste to energy plants to carbohydrates via photocatalytic reduction with water and further carbon coupling reactions is investigated. READ MORE

  5. 4. Photoredox catalysis with 10-phenyl-10H- phenothiazine and synthesis of a photocatalytic chiral proline-based organocatalyst

    University essay from KTH/Organisk kemi

    Author : Panagiotis Lamprianidis; [2020]
    Keywords : organic chemistry; photocatalysis; organocatalysis; organocatalyst; organic synthesis; organisk kemi; fotokatalys; organokatalys; organokatalysator; organisk syntes;

    Abstract : Photoredox catalysis applications for the purpose of new synthetic routes in organic and sustainable chemistry are hot topics in organic synthesis today. In the present study, the synthesis of a chiral proline-based organocatalyst functionalized with 10-phenyl-10H phenothiazine (PTH) photocatalytic moietiesis investigated and attempted for the first time.

  6. 5. Photocatalytic concrete/cement - how does it function and possible product areas

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Ozan Altan; [2010]
    Keywords : ;

    Abstract : Concrete is one of our most important and most widely used building material but the process of making concrete causes major environmental pressures. Concrete can also look dirty and boring with age, but some regard that the aging effects caused by algae and mosses provide a beautiful patina. READ MORE
