Redox stable solid oxide fuel cells are beneficial in many aspects such as tolerance against system failures e.g fuel cut off and emergency shut down, but also allow for higher fuel utilization, which increases efficiency. State-ofthe-art Ni-cermet based anodes suffer from microstructural changes upon redox cycling, w…
Perkembangan kebutuhan konsumsi baja dunia yang semakin meningkat telah memicu industri baja untuk meningkatkan kapasitas produksinya, akibatnya produksi bijih besi juga mengalami peningkatan. Pada penelitian ini teknologi yang digunakan untuk peleburan bijih besi adalah menggunakan metode reduksi langsung atau Direct…
Elm1p, a serine/threonine protein kinase, is required for coordination of cell growth and nuclear division in budding yeast. The primary sequence of Elm1p is only 30 to 40% identical to sequences of kinases with solved crystal structures. Thus, determining the crystal structure of Elm1p will expand current knowledge o…
Fine mesoporous TiO2 are usually cured at high temperatures by means of a slow convection heating procedure (up to 350 °C) in order to remove all organic components present in the used ink. However, this high sintering temperature in unusable for processing of TiO2 layers prepared on substrates with low heat resistanc…
Chemotherapeutic agents for treating various cancers show considerable side effects and toxicity. Often cancer relapses after initial response to the chemotherapy. Tumor cells are heterogeneous and have the progenitor stem cells which can renew, causing the relapse of the disease. To overcome drug resistance, metastas…
Hochwarmfeste ferritisch-martensitische Stahle mit 9-12 Gew.-% Chromgehalt werden wegen ihrer hohen Kriechfestigkeit und ihres gleichzeitig guten Oxidationswiderstands erfolgreich als Konstruktionswerkstoff fur Hochtemperaturbauteile in Kraftwerken eingesetzt. Die zunehmend zyklische Fahrweise konventioneller Kraftwer…
With the evolution of the high-trough-put screening (HTS) methods it is now possible to screen up to 100 000 pharmaceutical compounds each week and thus the amount of possible new active pharmaceutical ingredient (API) grow every week. Because of the fact that nearly half of the new API found today with the help of HT…

Silicon carbide (SiC) is an important material in industry due to its favorable mechanical, thermal, chemical, and electrical properties. While it has been mainly used as an abrasive material in the past, more modern applications like armor and other structural applications, often require densified ceramic bodies. SiC…
The Ph.D. thesis addresses the issues of elastomer seals operating in cold climate areas like Arctic. The work is devoted to a better understanding of low-temperature behaviour of elastomer seals near the glass transition Tg. The main objective of the work is to understand the causes for seal failures in cold environm…

Polymers have important and widespread applications in modern materials due to their excellent formability, chemical stability, light weight and low cost. Their production has increased exponentially over the last 60 years after their introduction to the markets from 1.5 million tons/year in 1950 to 322 million tons p…
Nowadays π-conjugated molecules are widely used as materials for devices in organic and molecular electronics. This is due to the ability of such molecules to conduct electricity. However, π-conjugation leads to molecular rigidness and associated lower solubility, which limits possible applications. Meanwhile, there a…
Solid solutions from the concentration range (0 ≤ x ≤ 1) was employed to grown (1-x)PbMg 1/3 Nb 2/3 O 3 - xPbTiO 3 single crystals using various heat treatment process under lower pressure. Transparent green and yellow colored single crystals of irrespective shapes are obtained. For the fabrication of (1-x)PMN-PT crys…
As a novel fluorescent material, carbon dots (CDs) demonstrate many excellent properties such as low toxicity, high stability and high resistance to photo bleaching. They are very likely to be applied in sensing, bio-imaging, photo catalysis and lighting devices, which require that the CDs can be tuneable in emission…
Co-crystallisation is currently a ‘hot topic’ in pharmaceutical development among other fields. Modification of the physicochemical properties of the parent material by inclusion of a second component within the crystal structure, with the potential to lead to large improvements in useful attributes, being the key rea…

The forward current-voltage (I-V) characteristics of oxidized Ni-Au and Ni-only Schottky contacts on n-type GaN were measured in the temperature range 160 K-400 K. The Schottky barrier diode whose barrier height (b) and ideality factor () are both bias dependent has been studied as a function of temperature using a te…
The solutions of the three-dimensional problem of the theory of elasticity are given, when on the boundaries of some parallel cylindrical cavities elastic stresses are given in the elastic space, but on the boundaries of other displacements. The solution of the Lame system of equations is obtained by the generalized F…
The purpose of this research is to study the mechanical and physical properties of coconut coir reinforced with polyester matrix composite by differencing their percentage of fibre loading and their coir fibre condition. The characterization of mechanical properties for the composition samples was determined by using…
