Synthesis, characteristics, and antibacterial effects of biomaterials in nanoscale
(2022)In this thesis, lignin/tannin nanoparticles (LNP/TNP) from different sources and processes were synthesized by nanoprecipitation method using lignin/acetone (and tannin/acetone) as solvents, and distilled water was used ...Embargo until/t.o.m. 21.1.2023 /asti. -
Proposal of a long-term water supply network to Honde Valley Ward 10
(2022)The thesis provides a technical framework of gravitationally fed water distribution systems in rural developing regions. The functionality of gravity-fed networks’ theory includes energy profiles in the network, pressures ... -
Fractionation and Characterisation of Enzymatic Hydrolysis Lignin
(2022)Lignin is one of the major components in lignocellulosic biomass and the most abundant aromatic building block in nature. Technical lignins extracted from either pulping or biorefining processes provide a variety of complex ... -
The effect of black liquor droplet in-flight time on kraft recovery boiler dust formation
(2021)Dust in kraft recovery boilers is primarily formed when compounds originating from sulphur and sodium released during black liquor combustion react with each other and the surrounding gases. Sulphur is released through ... -
Performance modeling of single-phase brazed plate heat exchangers
(2021)The design of heat exchangers for specific applications entails a number of different calculations in order to determine the appropriate dimensions and characteristics for the heat exchanger unit. The relevant equations ... -
A balance-based study of the combustion in blast furnace cowpers
(2021)This thesis focuses on modelling and simulation of different firing conditions in cowpers that are a part of a steelmaking process. The cowpers are regenerative heat exchangers that preheat the blast air into the blast ... -
Catalysts for slurry-phase hydrotreating of bio-oil
(2021)The European Green Deal, a policy initiative set by the European Commission, aims to reduce greenhouse gas (GhG) emissions, and ultimately achieve an economy with net-zero GhG emissions by 2050. Achieving these targets ... -
Compounding Toolbox for Polypropylene Film Recycling
(2021)The recyclability of materials and plastics in general has been discussed a lot in recent years. The majority of the plastic waste ends up in landfills and is being incinerated for energy. On the other hand, the recycling ... -
Hydrodeoxygenation of lignin-derived model compound isoeugenol over Fe-, Ni-, and Fe-Ni-supported on zeolites
(2021)As the world is transitioning away from fossil fuels, lignocellulosic biomass is scrutinized as a source of renewable fuels and chemicals. Political motivations and environmental concerns have increased the research in ... -
Control of the particle size distribution of a cement grinding circuit
(2021)For the past decades, the Blaine value has been the predominant characteristic when controlling the process parameters of a cement grinding circuit. The Blaine method measures the permeability of the cement, and therefore, ... -
Integration of machine learning models in a 3D simulated environment for surface ship navigation
(2021)This master’s thesis describes the process of integrating data generated by machine learning models into a simulation developed using AILiveSim, a tool running on Unreal Engine. The goal is to use this data to improve the ... -
Modular calculation and optimization toolkit for power plant applications
(2021)Automation is an ever-increasing phenomenon in today’s world, almost exponentially so. If a task is expected to be repeated in a predictable and quantifiable way, it will at some point be subject to automation. Naturally, ... -
Development of autonomous navigation systems for maritime applications
(2021)The interest in autonomous technology for transportation has grown significantly in the last decade and is slowly reaching the maritime industry as well. There are numerous potential benefits in using self-driving vehicles ... -
Estimation of Urea Dosage in an SCR Unit
(2021)Impositions of increasingly stringent restrictions on the harmful emissions of nitrogen oxides (NOx) from combustion engines have popularized the use of chemical exhaust gas treatment in the form of selective catalytic ...Kokoteksti on luettavissa vain Kirjatornissa ja Academill-kirjastossa. -
Non-halogenated fire retardant additives for an opaque exterior wood paint
(2021)This thesis focuses on finding effective and environmentally friendly fire retardant (FR) formulations for opaque exterior wood paints. The utilisation of green chemistry and incorporation of mineral-based FRs were deemed ... -
Inventory and management of process wastewater streams in a pharmaceutical production plant in Finland
(2021)Pharmaceuticals and their effects on the environment have become continually a more and more interesting topic. Even though only 2% of all European API (Active Pharmaceutical Ingredient) discharges are from the pharmaceutical ... -
Development of a novel artificial nose with conductive polymers of 3,4-ethylenedioxythiophene and its functionalised derivatives
(2021)Artificial noses are analytical instruments inspired by the human olfactory system and have been applied for qualitative analysis in many industrial fields, agriculture, forestry, environmental monitoring as well as medical ... -
Framställning av högbarriärpapper med reversgravyr
(2021)Målet med arbetet var att tillverka ett pappersbaserat barriärmaterial genom dispersionsbestrykning. Som substrat användes två papperssorter och bestrykningen bestod av barriärdispersioner med olika funktioner. Dispersionerna ... -
Data Pipelines and Edge Analysis in Engine Installations
(2021)In recent times, increasing processor power as well as more and new machine learning technology has led to increased interest in collecting and analyzing data, a trend which has come to be known as the internet of things ... -
