Over the past 30 years, severe demands have been placed on the pipe manufacturer with respect to the development and processing of materials to pipe line. Line pipe steel is put to extremely severe conditions like deep water, cold climate, corrosive and high pressure applications etc. Their quality requirements are be…
This Thesis deals with the results of different research topics aimed at the development of innovative, catalytic liquid-phase oxidation processes. All of them are characterized by the use of C6-based substrate and by targets which may fit the aim of a more sustainable industrial chemistry. \nFirst, the oxidative clea…
Lecithins, silanes, or nano-materials have been introduced into the host nematic (N) liquid crystal (LC) media for the automatic vertical alignment (VA) of LC, but these nano-materials create several problems such as aggregation with themselves, poor compatibility and interaction with host LCs. To overcome these drawb…
Tämä kandidaatintyö on kirjallisuustyö biomassaa hyödyntävien ORC-voimaloiden potentiaalista Suomessa. Työn tavoitteena on selvittää, missä teholuokissa prosessi soveltuisi käytettäväksi Suomessa ja mitkä tekijät mahdollistaisivat niiden yleistymisen. Lisäksi pohditaan ORC-prosessin etuja ja haittoja muihin biomassaa…
Adsorption equilibrium isotherms for N2, CO2, and CH4 on zeolite 13X were investigated at three different temperatures (25.5, 50.5 and 75.5 ̊ C) and a pressure range of (0-6.89475) MPa for CH4 and N2 and in the range of (0-4.82633) MPa for CO2 using built in volumetric apparatus. The results were validated using with…
Template-Free Synthesis of Hierarchical Porous Zeolitic Imidazole Frameworks Nanoparticles and their CO2 Sorption
Toilet, towel and facial products have important properties, for example, softness, absorption, wet strength and strength. Research has been undertaken to investigate the influence of pulp and proc ...
Marine diatoms that acquired a planktonic lifestyle predominantly belong to the radial and multipolar centrics and there are only several araphid and raphid pennate genera commonly found in the pelagic environment. The common adaptation to the planktonic existence is the formation of cell colonies which is acquired by…
Humanity has become reliant on cheap, readily available energy to power our devices and maintain our modern quality of life. The current source of this energy is primarily fossil fuel, a nonrenewable energy source that will not be able to supply our growing energy demands indefinitely. A push to find new sources of en…
Multidrug resistance is one of the main causes of ineffective treatment of ovarian cancer, which is the deadliest gynecological cancer today. Almost 80% of advanced cases have recurring malignancies after treatment, even after initial responsiveness to the usual platinum-based chemotherapeutics. One mechanism for resi…
Der nichtrostende, aushartbare Stahl 1.4542 (X5CrNiCuNb16-4) wird aufgrund der guten mechanischen Eigenschaften und der hohen Korrosionsbestandigkeit in einer Vielzahl von technischen Anwendungen eingesetzt. Das Verhaltnis zwischen den mechanischen Eigenschaften und der Korrosionsbestandigkeit wird durch eine gezielte…
This thesis analyses the structure, phase behaviour and dynamics of two dimensional (2D) systems of interacting soft-core particles, focussing in particular on how these can solidify and the properties of the resulting crystalline structures. Classical density functional theory (DFT) and dynamical density functional t…
Amorphous solid dispersions (ASDs) which are primarily comprised of drug(s) dispersed within a polymeric matrix are becoming increasingly prevalent as a formulation strategy to enhance the in vivo performance of poorly soluble compounds because of their ability to generate supersaturated solutions upon dissolution. Th…
Iron-based high temperature superconductors are a large family of materials that exhibit unconventional superconductivity and arise from antiferromagnetically-ordered parent compounds. One of the grand challenges in understanding the behavior of these materials is determining the physical mechanisms responsible for th…
To study NR mesostructure (macromolecular structure + aggregates or gels) (Figure 1), the NR sample is placed in a good solvent of polyisoprene (cyclohexane, toluene or tetrahydrofuran). In addition to a soluble fraction, there is always an insoluble fraction called macrogel (Figure 1) or gel depending on the authors…
Boiler adalah suatu alat yang berfungsi mengubah air (boiler waterfeed) menjadi uap (steam) pada tekanan dan temperatur tertentu melalui mekanisme heat transfer. Uap tersebut dapat digunakan untuk menggerakkan turbin. Boiler terdiri dari beberapa komponen yang membentuk suatu sistem untuk menghasilkan tenaga (power).…
Foi realizado um experimento de solidificacao da liga Nd 15 Fe 77,5 B 7,5 em forno de inducao a vacuo, com atmosfera de argonio, vazando-se o metal sobre uma coquilha de cobre refrigerada a agua, com objetivo de avaliar o efeito da taxa de resfriamento na microestrutura de solidificacao. A medicao das temperaturas ao…
Two-dimensional materials, such as graphene, hexagonal boron nitride, and transition metal dichalcogenides (TMDs) have gained much interest for their applications in nanoscale devices, especially nanoelectronics. In this regard, TMDs are particularly interesting, as this class of materials contains several stable comp…
Nowadays noise reduction constitutes a goal for every car manufacturer and a considerable effort is being made to produce components with low noise emission levels. Interactions between mechanisms undergoing friction are often associated with noise generation. This work is aimed to study the friction properties of two…
Carbon is the most abundant material next to oxygen in terms of sustainability. The potential of carbon based materials has been recognized in recent decades by the discovery of fullerene (1996 Nobel prize in chemistry), carbon nanotubes (2008 Kavli prize in nanoscience) and graphene (2010 Nobel prize in physics). The…
