CaCO3 scale inhibition in paper making processes – evaluation of testing methods and inhibitor performance
(2011)
Diplomityö
Diplomityö
The formation of an adherent layer of inorganic deposition on the surfaces of process equipment is called scaling. Scaling is a major problem in many industries using large quantities of water. One of these industries is ...
Double Melting Behavior and Plasticization of Polylactic acid – a TOPEM and FTIR Study
(2012)
Diplomityö
Diplomityö
The multiple melting behavior is a common phenomenon observed by differential scanning calorimetry (DSC) for polymorphic polymers. In the case of poly(lactic acid) (PLA) this is detected as double melting peaks, which have ...
Curvature Effects in Lipoprotein Fusion
(2011)
Diplomityö
Diplomityö
High and low density lipoproteins (HDL and LDL, respectively) are of tantamount interest to studies on human health, as these cholesterol transporters are highly involved in cardiovascular diseases, the leading cause of ...
Computer Simulations of Scanning Tunneling Microscopy of Adsorbate Molecules on Metal Surfaces
(2012)
Diplomityö
Diplomityö
Pyyhkäisytunnelointimikroskopia (eng. Scanning tunneling microscopy, STM) on yksi modernin pintatieteen tärkeimmistä työkaluista. Se mahdollistaa atomirakenteen kuvantamisen reaaliavaruudessa ja pintojen tutkimisen ...
Excited-State Intramolecular Proton Transfer in 10-Hydroxybenzo[h]quinoline Derivatives
(2012)
Diplomityö
Diplomityö
If a molecule contains a proton donor and a proton acceptor group in close proximity, an intramolecular hydrogen bond may be formed between the groups. Upon electronic excitation, a proton transfer from the donor to the ...
Position estimation using RSS measurements with unknown measurement model parameters
(2012)
Diplomityö
Diplomityö
The availability and performance of satellite-based navigation systems are the weakest in urban areas and indoor spaces, where the user density would be high. In these environments alternative low-cost positioning techniques ...
UV-light induced degradation of polypropylene and polystyrene – a spectroscopic and DSC study
(2012)
Diplomityö
Diplomityö
Ultraviolet (UV) radiation is an important factor affecting the life-time of polymer products. When polymers are exposed to UV radiation in the presence of oxygen they degrade due to photo-oxidative reactions. The changes ...
Expression and characterization of full length Interferon gamma in mammalian cells
(2012)
Diplomityö
Diplomityö
Interferon gamma (IFNγ) is an immunomodulatory cytokine hormone, which participates in producing a host defense response to viral and bacterial infections. It has an important role in coordinating expression of immunologically ...
Coarse Particle Pre-Separator for High Temperature Sampling
(2011)
Diplomityö
Diplomityö
The combustion of challenging fuels has become more important in recent years. This development with other recent interests has increased the importance of superheater high temperature corrosion. The aim of this thesis is ...
Ion gels as dielectrics in organic thin-film transistors
(2012)
Diplomityö
Diplomityö
Ion gels composed of ionic liquids and block copolymers can be used as gate dielectrics in organic thin-film transistors. Conventional dielectrics used in OTFTs do not have capacitances large enough to enable transistor ...
