Tämän kandidaatintyön tavoitteena on tutkia biomassan kuivausta. Työssä tutkitaan myös kuivauksen energiankulutusta ja ilmantarvetta teoreettisessa kuivausprosessissa sekä tutustutaan itse biomassan kuivumiseen käymällä läpi aiheeseen liittyvää kirjallisuutta ja tutkimuksia. Pääpaino työssä on kuitenkin tutkia biomass…
Geopolymer has gained its focus recently and are generally believed to have good fire resistance due to their ceramic-like properties. As timber structures are very much popular around the globe and this structure is also very vulnerable to fire so this geopolymer coating can be used to protect the timber from fire to…
In the course of miniaturizing modern technology down to the molecular scale, understanding the materials behavior has to be investigated and deviations from the bulk have to be understood. A combination of nano-sized relaxation spectroscopies (Broadband Dielectric Spectroscopy (BDS) and Specific Heat Spectroscopy (SH…
Huge development in the synthesis and processing of materials with nanostructures on nanometer length scales has created a demand for a deeper understanding of thermal and electro-thermal transport in nanoscale devices and nanostructured materials. Besides, heterogeneity of nanocomposite materials and devices has brou…
A finite element tool was used to simulate the structural and damage response of honeycomb sandwich composites subjected to low-velocity impact, under different energy. Damage evolution such as composite skins failure, and collapse of honeycomb core was assessment by different damage models. And interlaminar damage wa…
Nanophotonic devices hold promise to revolutionize the fields of optical communications, quantum computing and bioimaging. Designing viable solutions to these pressing problems require developing accurate models of the relevant systems. While a great deal of work has been performed in terms of developing individual mo…
Diese neue Ausgabe erfullt ihren Zweck, Stahlverbrauchern und Konstrukteuren einen kompakten Uberblick vergleichbarere russischer und europaischer Stahlsorten zu liefern.
The article deals with the safe design of the hydrogen storage tank, which includes a set of cylindrical metal containers made of stainless steel 12Х18Н10Т filled with carbon nanotubes; a cooling jacket made of liquid nitrogen in the likeness of a Dewar vessel into which metal containers with carbon nanotubes (SWNT) a…
Kontinuirno litje je pogosto uporabljen in privlacen tehnoloski proces v sodobni metalurski industriji. Kljub razsirjeni uporabi zaradi zapletenosti fizikalnih procesov v ozadju se vedno ni dobro opisano. Cilj tega prispevka je osnovati model termomehanskega vedenja pri kontinuirnem litju bakrenih zlitin z oblikovnim…
In spite of the reputation of homogenous transition metal catalyzed olefin polymerization to be a mature area of research and a massive industrial success, there still exist knowledge gaps concerning the control of, for example, the polymer molecular weight. This is primarily due to lack of understanding of the cataly…
Carbon nanocomposites have been successfully developed and applied in the field of energy storage and conversion such as supercapacitors and lithium ion batteries. The effects of controlled morphologies and structures have been fundamentally studied to enhance the electrochemical performance. The aim of this thesis is…
Starch pasting behavior greatly influences the texture of a variety of food products such as canned soup, sauces, baby foods, batter mixes etc. The annual consumption of starch in the U.S. is 3 million metric tons. It is important to characterize the relationship between the structure, composition and architecture of…
Reversible Fluorination of Graphene Induced by Electron Beam Irradiation: Towards the Band Gap Manipulation
An efficient energy provision using fuel cells is linked to effecitve hydrogen storage capabilities. Because of its low intrinsic hydrogen permeability, glass has a huge potential in modern concepts of hydrogen storage. Previous studies on oxidic glasses showed an empirical connection between glass composition and gas…
Detta examensarbete handlar om att undersoka stabiliteten hos Pickering emulsioner som bestar av myglyol olja, vatten, etanol och starkelse. Emulsioner med olje- och etanol i vattenhalt upp till 60 % samt 70 % visade sig vara stabila upp till fyra manader vid rumstemperatur. Detta tyder pa att Pickering emulsion ar st…
Il chitosano è un biopolimero di origine naturale, non tossico, con spiccata attività antibatterica e fotoreticolabile. Il processo di UV-grafting prevede l'aggraffaggio delle macromolecole di chitosano al tessuto tramite radiazione ultravioletta, in presenza di fotoiniziatore radicalico. Nella parte II è stato studia…

This thesis presents first-principles studies of electrochemical reactions at solid-liquid interfaces using transition metal electrodes within the framework of density functional theory (DFT). The thesis contains an extended introduction and three main sections of scientific results relating to nitric oxide (NO) elect…
The present thesis addresses several critical issues, associated with the development and design of CdTe-based solar cells. It aims at giving more insights into the interplay existing between the microstructure of CdTe absorber layers, and their electronic properties. To this end, a correlative study of CdTe absorber…
The TG-DSC investigation of the mixture energetic polymer MPVT and metal nanopowders has been conducted. The investigation conducted have established a dependency of the metal oxidation rate in MPVT polymer matrix on its chemical nature. Aluminum oxidation was established to be promoted by addition transition metals,…
