The cathode performance of solid oxide fuel cell (SOFC) depends substantially on its surface area, porosity and microstructure, and therefore the processing method is very important in determining cathode performance. By improving the structural characteristics of the layer, the cathode performance during fuel cell op…
In this study, the pattern of carbon dioxide generation from calcination of calcium carbonate are studied at different temperatures 600, 700 and 800oC. Besides, the morphology of activated char from the combination process of pyrolysis and calcination of calcium carbonate are investigated as the part of the objectives…
The project entitled surface effect of Magnesium-Aluminium and Lithium-Aluminium hydrotalcite based adsorbent in hydrogen adsorption which aims to determine the surface effect of modified adsorbent. The adsorbent were synthesized using coprecipitation method while surface modification performed by impregnation method.…
fick de svenska lagen en brons-och en silvermedalj när EUSO arrangerades i Klagenfurt, Österrike: Miranda Carlsson (lag A), Alicia van Hees (lag B), Tobias Wallström (lag B) Nedre: Ludvig Forslund (lag A),
Since decades, thermoelectricity is deeply studied as no-waste energy source. Thermoelectric (TE) materials allow the direct transformation of a heat source into an electrical current (Seebeck effect). TE conversion is very attractive as it is the strongest candidate for producing electricity from waste heat energy so…
Nowadays, natural gas is considered as one of the cleanest, safest gas and the most useful form of energy in our daily lives, its demand is increasing worldwide. One of the reasons the demand is still increasing is the presence of high amount of CO2 in natural gas. Removing bulk amount of CO2 from natural gas at high…
Formation of gas hydrate in oil and gas pipelines has resulted in flow assurance problem. Ionic liquid (IL), due to its dual functionality has been considered as a very promising hydrate inhibitors. However, experimental testing of IL alone is insufficient to examine all potential ILs combinations due to high number o…
In this study an attempt is made to create molecular dynamics (MD) models of borate glass, alkali borosilicate glasses, and UK vitreous High Level Radioactive Wasteforms. The study also includes experimental studies of vitrified wasteforms by helium pycnometry, scanning electron microscopy (SEM), energy dispersive X-r…
The objective of the NEAMS ToolKit is to develop a “pellet-to-plant” simulation capability useful for predicting performance and safety for a broad range of nuclear reactor power systems. The NEAMS ToolKit has been organized into a Fuels Product Line (FPL) and a Reactor Product Line (RPL) and is modular in design. Wit…
A detailed powder neutron diffraction study coupled with a complementary characterisation of the ferroelectricity and ferromagnetism, concerning two different compositions based on a parent BiFeO3 crystal lattice. The addition of Dy3+ into BiFeO3 ceramics shows how the parent polar R3c symmetry destabilises due to str…
Front Cover: Polymer carbon nanotube nanocomposites are prepared by melt-mixing a poly(oxymethylene)/poly(l-lactic acid) (POM/PLLA) blend and multiwalled carbon nanotubes (MWCNTs). Investigation of the crystallization behaviour shows that the MWCNTs first selectively nucleate POM to yield novel “mace-like” hybrid stru…
Congratulations to the winners of the sixth annual Microscopy Today Innovation Awards competition. These awards honor innovative microscopy-related products and methods that appeared in the previous year. Our team of judges, led by Tom Kelly, looked for innovations that will make new scientific investigations possible…
Back Cover: Top-down multidimensional mass spectrometry, interfacing electrospray ionization (ESI) with ion mobility mass spectrometry (IM-MS) and energy resolved (gradient) tandem mass spectrometry (gMS2), reveals the stoichiometries, architectures, and intrinsic stabilities of coordinatively bound supramolecular pol…

Abstract Compounds (IV) and (V) are characterized by single crystal XRD, solid state NMR spectroscopy, Raman spectroscopy, and quantum chemical DFT calculations.
The paper presents a testing technique for structures of layered reinforced concrete with corrosion damage and shear cracks for strength and crack resistance study, which is aimed at determination of experimental parameters of shear between concrete layers, unequal deforma- tion of concrete and reinforcement and effec…
Abstract γ‐CoOOH nanosheets are prepared by oxidation of a hydrothermally prepared α‐Co(OH)2 alkaline aqueous suspension using NaClO (5.2 wt.%) under vigorous stirring followed by exfoliation through ultrasonication (12 h).
A method of accelerated evaluation of the impact strength KCV in the brittle-ductile transition range is developed. The unified impact strength diagram for steels is ob- KCV T HBp tained. A unified linear relationship KCV t over KCV p = f KCV p HB T ( is derived within a temperature range of 77 - 473 K where the subsc…
Polymer-inorganic nanocomposite membrane was successfully prepared via incorporation of nitrogen doped (N-doped) titanium dixide (TiO2) anatase/rutile mixed phase nanorods in the cellulose microfiber by using phase inversion technique. The use of the non-toxic solvent-based system and recycled newspapers as the cellul…
