Using alcohol as a carrier producing polyanionic cellulose (PAC) polymer from solid textile waste

Karakuş, Hüseyin

Cellulose is the most abundant organic polymer on earth. It is naturally regenerated by forests and cotton plantations with a speed of 10 billion metric tons per year regularly. Not only its natural reproduction makes it ecologically beneficial but also its biological degradability makes cellulose an ‘eco-friendly material’. Applications of cellulose is limited due to its insolubility in water. Contrarily, its water-soluble derivatives, especially cellulose ethers, are found in nearly all the products we are using in our daily life. Although cellulose is the main raw material for producing ce ...Daha fazlası

Synthesis, characterizatıon and application of new organic electroactive molecules for photovoltiıc devices

PEDOT:PSS is with its acidic property solves the indium atoms from ITO and indium atoms diffuses in active layer in an organic solar cell. This event causes an decreasing in solar cell efficiency. In the same strategy, SAM molecules can be used as hole injection layer. On the other hand MoO3 can be used as anode buffer layer. In this thesis it is wanted to make SAM molecules have to not absorb visible range of solar spectrum for the efficient harvesting of solar energy by donor molecule. Otherwise the HOMO level of SAM molecule have to be between work function of ITO and HOMO level of donor mo ...Daha fazlası

Synthesis of imidazole derivatives and their binderless immobilization to fabric to load antibacterial properties

Mutlu, Nurgül

The compounds bonded with functional groups in textile materials carry the economical support material property. The complex and/or organic compounds with the desired properties can be immobilized into the textile materials by using the reactivity of hydroxyl groups of cellulose and the NH2 groups in wool. Most of commercially purchased silver salts show a rapid release of silver in water because of their ionic structure. For this reason, they exhibit high antibacterial activity but the short-term. N-heterocyclic carbene (NHC) complexes have the long-term antibacterial effects by releasing the ...Daha fazlası

Synthesis and application of the iridium semiconductor complexes for organic light emitting diodes

Organic light emitting diodes (OLEDs) is a multi-disciplinary research area. Due to the possibility of being produced in different designs and low costs, studies on the research and development of energy efficient structures have increased. These expectations have increased so much that research on new types of molecules and device designs is increasing with the expectation that OLEDs will be more efficient than all available light sources and that almost 100% of the energy used can be converted to light. Transition metal complexes, especially Iridium(III) complexes, which make them phosphores ...Daha fazlası
