1. 1. Hybrid Mismatches in International Transactions : A Study of Linking Rules in EU and Tax Treaty Law

   Författare :Autilia Arfwidsson; Martin Berglund; Claes Norberg; Jesper Johansson; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; hybrid mismatch; linking rules; hybrid mismatches; hybrid mismatch rules; taxation; international taxation; tax treaty; OECD MTC; BEPS; EU law; ATAD; Finansrätt; Fiscal Law;

   Sammanfattning : Hybrid mismatches, where differences in income characterisation across jurisdictions lead to double non-taxation, can be exploited by multinational enterprises to reduce their overall tax burden. Common hybrid mismatch rules addressing this issue have recently been introduced within the EU and the OECD. LÄS MER

3. 2. Using Low Energy Light to Enable High Energy Photochemistry

   Författare :Wera Larsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triplet-triplet annihilation; solar energy conversion; photochemistry; molecular photoswitches; photochemical upconversion; triplet sensitization; fluorescence modulation;

   Sammanfattning : Manipulating light to meet human needs is pivotal in various research fields and technological applications, ranging from solar energy conversion to photodynamic therapy and fluorescence imaging of cells and tissues. This thesis addresses the spectral mismatches between available light and the specific energy requirements of target photochemical reactions by employing low-energy light to control high-energy photochemistry.
