The optimization of the soot degradation during the engine combustion will be investigated. The aim is to evaluate the potential of nanomaterial to promote a more efficient elimination of particles produced by the diesel engine.
The student will then have to use the x-ray tomography at the Institute of Technology to study how the filter is covered with soot and if the nanomaterial coating is still there and help improving the decomposition of soot produced by diesel combustion.

The student should have skills in engineering, engine mechanics, gas combustion and workshop utilization. He will first propose different set-ups and discuss realistic options.
The set-up should have limited size and be adaptable to the set-up that already exists at the Institute of technology. The student will have to solve certain engineering problems: 1 Prepare a set-up that can be coated with nanomaterials with realistic options 2 Build the set-up that can be adapted to the Engine test lab at the Institute of technology.

Photovoltaic devices have been recognized as a promising renewable energy technology and the growth of photovoltaic applications has been exponential since We have developed a new nanocomposite based on HfO2-CNT-Ag that can produce a photocurrent under UV or visible light excitation with enhanced photocurrent yield.
This present topic will take the subject further and assess the impact of Ag nanoparticles on the photocurrent generation properties of HfO2-CNT.
For this, the student will have to build a sample holder with different type of electrodes that can measure the photocurrent from different amounts of powder samples of HfO2-CNT-Ag from 1mg to 1g. It should be possible to illuminate the sample with multiple light sources. At the end of this practical phase, the student will have skills needed 1 to fabricate a photovoltaic device, 2 to find methods to measure very small currents in nanoAmpere, 3 to calibrate the illumination-current device for these nanocomposites 4 to work in collaboration with other experts Keywords: photocurrent, electrodes, illumination, nanocomposites Language: The working language is English Expected time for thesis defense: June 9.
However, p-type ZnO is very difficult to obtain as the intrinsic nature of ZnO remains n-type.
In such a case, the polymer is the p-type material necessary for forming the p-n junction. Nanomaterials are very important presently as they are more efficient than then their bulk counterparts are. They are employed in many applications, for example, hybrid materials can be applied to biomedical applications, as many polymers are compatible with tissues. At the end of this practical phase, the student will have skills needed 1 to fabricate a LED using nanomaterials, 2 to find methods to measure and apply very small voltages, 3 to test the emission wavelengths of the diodes Further information about ZnO semiconductors: Keywords: LED, device, wavelength of light emitted Language: The working language is English Expected time for thesis defense: June Conception of a water set-up for testing water purification and influence of flow.
However, to extend the developed technology to industrial processes, it is necessary to build a set-up to test the developed nanomaterials at higher scale than lab-scale. The set-up should include tubes and pipes of different diameter that can contain different filtering materials like activated carbon, sand, glass… The preferred material for the pipes is Plexiglas. A pumping system to feed the pipeline circuit should be adapted to the set-up.
In addition, a set-up that enables magnetic extraction should be adapted on one water line.
The 3D printer will be used to build specific part of the set-up that should be movable and will be fixed on a wood panel. The student should have skill in engineering, mechanics and workshop utilization.
He will first draw possible blue print for the set-up and discuss realistic option. The set-up should include options and it should be possible to modify it in the future if needed.
In order to reduce the generation of waste from disposable packaging, a directive of the European Parliament and Council was also passed, according to which a large part of disposable plastic products will be banned from the market in European Union at the beginning of Consequently, the aim of the author is to find out the current practices of Wolt's partners in packaging the takeaway food and their readiness to replace disposable packaging with a more environmentally friendly alternative.
In the theoretical part of the work, the author describes the activities of the European Union to reduce waste generation and the different reasons why the use of packaging needs to be regulated at the European Union level. The author also provides an overview of various possible solutions that catering companies could use to reduce the negative effects of the amendment on the company's operations based on scientific sources.
In order to find out what are the habits of catering companies in the packaging of the food they sell and what is Centrs Pro juhendamise susteem readiness to use more sustainable alternatives in the packaging of food, the author conducted a survey among Wolt partners.
The results of the study revealed that for the vast majority of Wolt partners who participated in the study, the sustainability of disposable packaging is rather important today.

Many companies have completely or largely abandoned the use of disposable plastics, and many companies are also open to using more innovative alternatives of packaging of takeaway foods. Sustainability is an important key word in the companies surveyed, but it was expected that profitability and maintaining food quality until the end of the process would remain just as important.
Praegu on toidu kohalevedu üks kõige populaarsem vahendusplatvormide teenus ning Eestis on üheks selliseks platvormiks Wolt. Toidu kaasostu ja kulleriteenuse sektori tähtsuse suurenemisega on esile kerkinud mitmeid jätkusuutlikkusega seotud probleeme, sealhulgas ka ühekordselt kasutatavate konteinerite kasutamine, mille taaskasutamise võimalused on väga väikesed. Ühekordsetest pakenditest tuleneva jäätmetekke vähendamiseks võeti vastu ka Euroopa Parlamendi ja Nõukogu direktiiv, mille kohaselt keelustatakse suur osa ühekordsete plast toodete turule laskmine Euroopa Liidu liikmesriikides aasta alguses. Sellest tulenevalt on töö autori eesmärgiks välja selgitada Wolt koostööpartnerite tänased praktikad kaasa ostetava toidu pakendamisel ning valmisolek asendada ühekordsed pakendid keskkonnasäästlikuma alternatiivi vastu. Töö teoreetilises osa kirjeldab autor Euroopa Liidu tegevusi jäätmetekke vähendamiseks ning erinevaid põhjuseid, miks vajab pakendite kasutamine Euroopa Liidu tasandil reguleerimist.
